2025-04-29 14:37:29A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:
“I just feel like I’m so behind.”
Behind who? Behind what?
There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.
Where did this come from?
Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.
But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.
Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.
I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.
“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?
If you need a permission slip to stop comparing, let this be it.
You’re not late. You’re not early.
You’re right on time. -

2025-04-29 14:37:27There’s something sacred about morning air — the way it carries just enough chill to remind you you’re alive, without pushing you back inside. I’ve been starting my days on the balcony lately. Not because it’s glamorous (it isn’t), or because I have a routine (I don’t), but because it’s the only space in my apartment that feels both open and still.
This morning I made coffee with too much cinnamon and curled up with a blanket that’s seen better days. I watched the city slowly wake up — one barking dog, two joggers, and the clatter of a recycling truck below. It’s odd how these tiny patterns become a kind of comfort.
I used to think that slowing down meant falling behind. But here, perched on the third floor with my feet on cold concrete and the sky just starting to blush, I feel like I’m exactly where I’m supposed to be.
If you’re reading this, maybe you needed that reminder too.

2025-04-29 13:46:37GitHub Actions (CI/CD) over Nostr
I Spent quite a bit of time on getting Nostr-based GitHub actions working. I have a basic runner implementation now, which i've reworked quite a bit when working with @dan on getting the front-end of it into gitworkshop.dev. We found that the nature of these jobs don't really lend itself to fit within the NIP-90 DVM spec.
What we have now: - A dvm-cicd-runner that - Advertises itself using NIP-89 announcements. - Takes a DVM request with: - repository - branch/ref - path to workflow file (
.yml
) - job timeout (max duration) - 🥜 Cashu prepayment for the job timeout (to be refunded) - Pulls the repository and executes the provided workflow file - Sends logs in batches as partial job results - Publishes job results and gets displayed in gitworkshop - Gitworkshop.dev (all nostr:npub15qydau2hjma6ngxkl2cyar74wzyjshvl65za5k5rl69264ar2exs5cyejr work) UI that : - Shows available workflow runners. - Instructing + paying runner to execute workflow file - Displaying job status, live updating with the latest logs / autoscroll, all the stuff you'd expect - Neatly displaying past jobs for the current repositoryTODO'S + Ideas/vision
- TODO: refunding the unused minutes (job timeout - processing time) to the requester
- TODO: create seperate kinds/nip for worflow execution over nostr
- Create separate kinds for streaming arbitrary text data over nostr (line by line logs)
- automated git watchers for projects to kick of jobs
- Separate out workflow management stuff from gitworkshop.dev. A micro-app might serve better to manage runners for git projects etc and takes away pressure from gitworkshop.dev to do it all.
- Perhaps support just running .yaml files, without the requirement to have it in a git repo. Could just be a .yaml file on blossom.
TollGate
I spent most of my time working on TollGate. There's been a lot of back and forth to the drawing board to narrow down what the TollGate protocol looks like. I helped define some concepts on implementing a tollgate which we could use as language to discuss the different components that are part of a tollgate implementation. It helped us narrow down what was implementation and what is part of the protocol.
Current state of the project
- We have a website displaying the project: TollGate.me
- Worked on a basic android app for auto payments, validating we can auto-buy from tollgates by our phones
- Presented TollGate at @Sats 'n Facts
- There's a protocol draft, presented at SEC-04
- We've done workshops, people were able to turn an OpenWRT router into a TollGate
- Building and releasing TollGate as a singular OpenWRT package, installable on any compatible architecture
- Building and releasing TollGate OS v0.0.1 (prebuilt OpenWRT image), targeting a few specific routers
- First tollgate deployed in the wild!! (At a restaurant in Funchal, Madeira)
- Other developers started to make their own adjacent implementations, which decentralizes the protocol already
What's next:
- We're gathering useful real user feedback to be incorporated in OS v0.0.2 soon
- Refine the protocol further
- Showing TollGate at various conferences in Europe throughout the summer
- Keep building the community, it's growing fast
Epoxy (Nostr based Addressing)
Although i've pivoted towards focusing on TollGate I worked out an implementation of my NIP-(1)37 proposal. During SEC-04 I worked out this browser plugin to demonstrate one way to make websites resistant to rugpulls.
It works by looking for a
meta
tag in the page'shead
:html <meta name="nostr-pubkey" relays="relay.site.com,other.relay.com">[hexPubkey]</meta>
When we've never recorded a pubkey for this domain, we save it. This pubkey now serves as the owner of the website. It looks for a kind
11111
event of that pubkey. It should list the current domain as one of it's domains. If not, it shows a warning.The key concept is that if we visit this website again and one of these scenario's is true: - There is no longer a
meta
tag - There's another pubkey in themeta
tag - The pubkey is still on the webpage, but the11111
no longer lists this domainThen we consider this domain as RUGPULLED and the user gets an error, suggesting to navigate to other domain listed by this
pubkey
. I'd like it to perhaps auto-redirect to another domain listed by the owner, this is especially useful for frequently rugged domains.This extension does try to solve a bootstrapping problem. We need to establish the website's pubkey at some point. We have to start somewhere, which is why the first load is considered as the 'real' one, since we have no way of knowing for sure.

🥜/⚡️ Receipt.Cash - Social Receipt sharing app
During SEC I worked on scratching an itch that has been lingering in my mind since SEC-03 already. And now that vibecoding is a thing it wasn't this huge undertaking anymore to handle the front-end stuff (which i suck at).
The usage scenario is a bunch of bitcoiners that are at a restaurant, we get the bill and want to split it amongst each other. One person can pay the bill, then: - Payer photographs receipt - Payer adds Cashu Payment request - Payer sets dev split % - App turns the receipt + request into a (encrypted) nostr event - The payer shares the event with QR or Share Menu
The friend scan the QR: - Receipt is loaded and displayed - Friend selects items they ordered - Friend hits pay button (⚡️Lightning or 🥜Cashu) and pays - Payment gets sent to Payer's cashu wallet - Dev split set by Payer goes to dev address.
Some features: - Change LLM model that processes the receipt to extract data - Proofs storage + recovery (if anything fails during processing)
Todo's: - Letting payer configure LNURL for payouts - Letting payer edit Receipt before sharing - Fix: live updates on settled items
The repo: receipt-cash

2025-04-29 13:38:49The vag' sits on the edge of the highway, broken, hungry. Overhead flies a transcontinental plane filled with highly paid executives. The upper class has taken to the air, the lower class to the roads: there is no longer any bond between them, they are two nations."—The Sovereign Individual
Fire
I was talking to a friend last night. Coffee in hand. Watching flames consume branches. Spring night on his porch.
He believed in America's happy ending. Debt would vanish. Inflation would cool. Manufacturing would return. Good guys win.
I nodded. I wanted to believe.
He leaned forward, toward the flame. I sat back, watching both fire and sky.
His military photos hung inside. Service medals displayed. Patriotism bone-deep.
The pendulum clock on his porch wall swung steadily. Tick. Tock. Measuring moments. Marking epochs.
History tells another story. Not tragic. Just true.
Our time has come. America cut off couldn't compete. Factories sit empty. Supply chains span oceans. Skills lack. Children lag behind. Rebuilding takes decades.
Truth hurts. Truth frees.
Cycles
History moves in waves. Every 500 years, power shifts. Systems fall. Systems rise.
500 BC - Greek coins changed everything. Markets flourished. Athens dominated.
1 AD - Rome ruled commerce. One currency. Endless roads. Bustling ports.
500 AD - Rome faded. Not overnight. Slowly. Trade withered. Cities emptied. Money debased. Roads crumbled. Local strongmen rose. Peasants sought protection. Feudalism emerged.
People still lived. Still worked. Horizons narrowed. Knowledge concentrated. Most barely survived. Rich adapted. Poor suffered.
Self-reliance determined survival. Those growing food endured. Those making essential goods continued. Those dependent on imperial systems suffered most.
1000 AD - Medieval revival began. Venice dominated seas. China printed money. Cathedrals rose. Universities formed.
1500 AD - Europeans sailed everywhere. Spanish silver flowed. Banks financed kingdoms. Companies colonized continents. Power moved west.
The pendulum swung. East to West. West to East. Civilizations rose. Civilizations fell.
2000 AD - Pattern repeats. America strains. Digital networks expand. China rises. Debt swells. Old systems break.
We stand at the hinge.
Warnings
Signs everywhere. Dollar weakens globally. BRICS builds alternatives. Yuan buys oil. Factories rust. Debt exceeds GDP. Interest consumes budgets.
Bridges crumble. Education falters. Politicians chase votes. We consume. We borrow.
Rome fell gradually. Citizens barely noticed. Taxes increased. Currency devalued. Military weakened. Services decayed. Life hardened by degrees.
East Rome adapted. Survived centuries. West fragmented. Trade shrank. Some thrived. Others suffered. Life changed permanently.
Those who could feed themselves survived best. Those who needed the system suffered worst.
Pendulum
My friend poured another coffee. The burn pile popped loudly. Sparks flew upward like dying stars.
His face changed as facts accumulated. Military man. Trained to assess threats. Detect weaknesses.
He stared at the fire. National glory reduced to embers. Something shifted in his expression. Recognition.
His fingers tightened around his mug. Knuckles white. Eyes fixed on dying flames.
I traced the horizon instead. Observing landscape. Noting the contrast.
He touched the flag on his t-shirt. I adjusted my plain gray one.
The unpayable debt. The crumbling infrastructure. The forgotten manufacturing. The dependent supply chains. The devaluing currency.
The pendulum clock ticked. Relentless. Indifferent to empires.
His eyes said what his patriotism couldn't voice. Something fundamental breaking.
I'd seen this coming. Years traveling showed me. Different systems. Different values. American exceptionalism viewed from outside.
Pragmatism replaced my old idealism. See things as they are. Not as wished.
The logs shifted. Flames reached higher. Then lower. The cycle of fire.
Divergence
Society always splits during shifts.
Some adapt. Some don't.
Printing arrived. Scribes starved. Publishers thrived. Information accelerated. Readers multiplied. Ideas spread. Adapters prospered.
Steam engines came. Weavers died. Factory owners flourished. Villages emptied. Cities grew. Coal replaced farms. Railways replaced wagons. New skills meant survival.
Computers transformed everything. Typewriters vanished. Software boomed. Data replaced paper. Networks replaced cabinets. Programmers replaced typists. Digital skills determined success.
The self-reliant thrived in each transition. Those waiting for rescue fell behind.
Now AI reshapes creativity. Some artists resist. Some harness it. Gap widens daily.
Bitcoin offers refuge. Critics mock. Adopters build wealth. The distance grows.
Remote work redraws maps. Office-bound struggle. Location-free flourish.
The pendulum swings. Power shifts. Some rise with it. Some fall against it.
Two societies emerge. Adaptive. Resistant. Prepared. Pretending.
Advantage
Early adapters win. Not through genius. Through action.
First printers built empires. First factories created dynasties. First websites became giants.
Bitcoin followed this pattern. Laptop miners became millionaires. Early buyers became legends.
Critics repeat themselves: "Too volatile." "No value." "Government ban coming."
Doubters doubt. Builders build. Gap widens.
Self-reliance accelerates adaptation. No permission needed. No consensus required. Act. Learn. Build.
The burn pile flames like empire's glory. Bright. Consuming. Temporary.
Blindness
Our brains see tigers. Not economic shifts.
We panic at headlines. We ignore decades-long trends.
We notice market drops. We miss debt cycles.
We debate tweets. We ignore revolutions.
Not weakness. Just humanity. Foresight requires work. Study. Thought.
Self-reliant thinking means seeing clearly. No comforting lies. No pleasing narratives. Just reality.
The clock pendulum swings. Time passes regardless of observation.
Action
Empires fall. Families need security. Children need futures. Lives need meaning.
You can adapt faster than nations.
Assess honestly. What skills matter now? What preserves wealth? Who helps when needed?
Never stop learning. Factory workers learned code. Taxi drivers joined apps. Photographers went digital.
Diversify globally. No country owns tomorrow. Learn languages. Make connections. Stay mobile.
Protect your money. Dying empires debase currencies. Romans kept gold. Bitcoin offers similar shelter.
Build resilience. Grow food. Make energy. Stay strong. Keep friends. Read old books. Some things never change.
Self-reliance matters most. Can you feed yourself? Can you fix things? Can you solve problems? Can you create value without systems?
Movement
Humans were nomads first. Settlers second. Movement in our blood.
Our ancestors followed herds. Sought better lands. Survival meant mobility.
The pendulum swings here too. Nomad to farmer. City-dweller to digital nomad.
Rome fixed people to land. Feudalism bound serfs to soil. Nations created borders. Companies demanded presence.
Now technology breaks chains. Work happens anywhere. Knowledge flows everywhere.
The rebuild America seeks requires fixed positions. Factory workers. Taxpaying citizens in permanent homes.
But technology enables escape. Remote work. Digital currencies. Borderless businesses.
The self-reliant understand mobility as freedom. One location means one set of rules. One economy. One fate.
Many locations mean options. Taxes become predatory? Leave. Opportunities disappear? Find new ones.
Patriotism celebrates roots. Wisdom remembers wings.
My friend's boots dug into his soil. Planted. Territorial. Defending.
My Chucks rested lightly. Ready. Adaptable. Departing.
His toolshed held equipment to maintain boundaries. Fences. Hedges. Property lines.
My backpack contained tools for crossing them. Chargers. Adapters. Currency.
The burn pile flame flickers. Fixed in place. The spark flies free. Movement its nature.
During Rome's decline, the mobile survived best. Merchants crossing borders. Scholars seeking patrons. Those tied to crumbling systems suffered most.
Location independence means personal resilience. Economic downturns become geographic choices. Political oppression becomes optional suffering.
Technology shrinks distance. Digital work. Video relationships. Online learning.
Self-sovereignty requires mobility. The option to walk away. The freedom to arrive elsewhere.
Two more worlds diverge. The rooted. The mobile. The fixed. The fluid. The loyal. The free.
Hope
Not decline. Transition. Painful but temporary.
America may weaken. Humanity advances. Technology multiplies possibilities. Poverty falls. Knowledge grows.
Falling empires see doom. Rising ones see opportunity. Both miss half the picture.
Every shift brings destruction and creation. Rome fell. Europe struggled. Farms produced less. Cities shrank. Trade broke down.
Yet innovation continued. Water mills appeared. New plows emerged. Monks preserved books. New systems evolved.
Different doesn't mean worse for everyone.
Some industries die. Others birth. Some regions fade. Others bloom. Some skills become useless. Others become gold.
The self-reliant thrive in any world. They adapt. They build. They serve. They create.
Choose your role. Nostalgia or building.
The pendulum swings. East rises again. The cycle continues.
Fading
The burn pile dimmed. Embers fading. Night air cooling.
My friend's shoulders changed. Tension releasing. Something accepted.
His patriotism remained. His illusions departed.
The pendulum clock ticked steadily. Measuring more than minutes. Measuring eras.
Two coffee cups. His: military-themed, old and chipped but cherished. Mine: plain porcelain, new and unmarked.
His eyes remained on smoldering embers. Mine moved between him and the darkening trees.
His calendar marked local town meetings. Mine tracked travel dates.
The last flame flickered out. Spring peepers filled the silence.
In darkness, we watched smoke rise. The world changing. New choices ahead.
No empire lasts forever. No comfort in denial. Only clarity in acceptance.
Self-reliance the ancient answer. Build your skills. Secure your resources. Strengthen your body. Feed your mind. Help your neighbors.
The burn pile turned to ash. Empire's glory extinguished.
He stood facing his land. I faced the road.
A nod between us. Respect across division. Different strategies for the same storm.
He turned toward his home. I toward my vehicle.
The pendulum continued swinging. Power flowing east once more. Five centuries ending. Five centuries beginning.
"Bear in mind that everything that exists is already fraying at the edges." — Marcus Aurelius
Tomorrow depends not on nations. On us.

2025-04-29 12:23:09In a vast digital realm, two cities stood side by side: the towering, flashing metropolis of Feedia, and the decentralized, quiet city of Nostra.
Feedia was loud—blinding, buzzing, and always on. Screens plastered every wall, whispering the latest trends into citizens’ ears. But in this city, what you saw wasn’t up to you. It was determined by a towering, unseen force known as The Algorithm. It didn’t care what was true, meaningful, or helpful—only what would keep your eyes glued and your attention sold.
In Feedia, discovery wasn’t earned. It was assigned.
And worse—there was a caste system. To have a voice, you needed a Blue Check—a glowing badge that marked you as “worthy.” To get one, you had to pay or play. Pay monthly dues to the high towers or entertain The Algorithm enough to be deemed “valuable.” If you refused or couldn’t afford it, your voice was cast into the noise—buried beneath outrage bait and celebrity screams.
The unmarked were like ghosts—speaking into the void while the checked dined in Algorithm-favored towers. It was a digital monarchy dressed up as a democracy.
Then, there was Nostra.
There were no glowing checkmarks in Nostra—just signal. Every citizen had a light they carried, one that grew brighter the more they contributed: thoughtful posts, reshared ideas, built tools, or boosted others. Discovery was based not on payment or privilege, but participation and value.
In Nostra, you didn’t rise because you paid the gatekeeper—you rose because others lifted you. You weren’t spoon-fed; you sought, you found, you earned attention. It was harder, yes. But it was real.
And slowly, some in Feedia began to awaken. They grew tired of being fed fast-food content and ignored despite their voices. They looked across the river to Nostra, where minds weren’t bought—they were built.
And one by one, they began to cross.

2025-04-29 11:28:01On Black-Starting the United Kingdom
In the event of a total failure of the electric grid, the United Kingdom would face a task at once technical and Sisyphean: the so-called black start — the reawakening of the nation’s darkened arteries without any external supply of power. In idealized manuals, the task is rendered brisk and clean, requiring but a few days' labor. In the world in which we live, it would be slower, more uncertain, and at times perilously close to impossible.
Let us unfold the matter layer by layer.
I. The Nature of the Undertaking
A black start is not a mere throwing of switches, but a sequential ballet. Small generating stations — diesel engines, hydro plants, gas turbines — must first breathe life into cold transmission lines. Substations must be coaxed into readiness. Load must be picked up cautiously, lest imbalance bring the whole effort to naught. Islands of power are stitched together, synchronized with exquisite care.
Each step is fraught with fragility. An unseen misalignment, an unsignaled overload, and hours of labor are lost.
II. The Dream of the Engineers
In theory, according to the National Grid Electricity System Operator (ESO), the sequence would unfold thus: within half a day, core transmission lines humming; within a day or two, hospitals lit and water flowing; within three days, cities reawakened; within a week, the nation, broadly speaking, restored to life.
This vision presupposes a fantasy of readiness: that black-start units are operational and plentiful; that communications systems, so delicately dependent on mobile networks and the internet, endure; that personnel, trained and coordinated, are on hand in sufficient numbers; and that no sabotage, no accident, no caprice of nature interrupts the dance.
III. The Real Order of Things
Reality is more obstinate. Many black-start capable plants have been shuttered in the name of efficiency. The financial incentives once offered to private generators for black-start readiness were judged insufficient; the providers withdrew.
Grid operations now rely on a lattice of private interests, demanding slow and complicated coordination. Telecommunications are vulnerable in a deep blackout. The old hands, steeped in the tacit lore of manual restoration, have retired, their knowledge scattered to the four winds. Cyber vulnerabilities have multiplied, and the grid’s physical inertia — the very thing that grants a system grace under perturbation — has grown thin, leaving the UK exposed to sudden collapses should synchronization falter.
Under such conditions, the best of hopes might yield five to ten days of partial recovery. Weeks would be required to restore the former web of normalcy. In certain cases — in the face of physical damage to high-voltage transformers, whose replacements take months if not years — black-start might founder altogether.
IV. The Quiet Admissions of Officialdom
In its polite documents, the National Grid ESO speaks carefully: essential services might see restoration within three days, but full public service would require "up to a week or longer." If designated black-start units were to fail — a real risk, given recent audits showing many unready — the timelines would stretch indefinitely.
In plain speech: in a true national blackout, the nation’s restoration would be a gamble.
V. The Forking Paths Ahead
If all proceeds well, Britain might stumble into light within three days. If the adversities accumulate — cyberattack, internal sabotage, simple human miscalculation — the process would stretch into weeks, even months. In the gravest scenarios, the nation would reconstitute not as one great engine, but as isolated islands of power, each jury-rigged and vulnerable.
Meanwhile, the paradoxical truth is that small and simple systems — the grids of Jersey, Malta, and the like — would outpace their mightier cousins, not despite their modest scale but because of it.
VI. Conclusion
The British grid, in short, is a triumph of late modernity — and like all such triumphs, it carries within itself the seeds of its own fragility. It works magnificently until the day it does not. When that day comes, recovery will be neither swift nor sure, but a slow, halting reweaving of threads too easily frayed.

2025-04-29 09:46:02In Jericoacoara, Brazil, a beach town famed for its natural beauty and vibrant tourism, an innovative project is quietly reshaping how locals and visitors think about money. Praia Bitcoin is an ambitious initiative to build a circular economy powered entirely by Bitcoin.
Launched in 2021 by entrepreneur Fernando Motolese, Praia Bitcoin was inspired by the Bitcoin Beach project in El Zonte, El Salvador. The vision is simple: create a self-sustaining Bitcoin economy where businesses and individuals use Bitcoin everyday in place of fiat money.
This idea holds special significance in Jericoacoara, where traditional banking services are scarce. The town lacks even basic infrastructure like ATMs, making financial inclusion a pressing need. With Praia Bitcoin, Bitcoin isn’t just a store of value—it’s a tool to empower a community and connect it to the global economy.
Transforming Jericoacoara with Bitcoin
Since its inception, Praia Bitcoin has worked to foster Bitcoin adoption in the area. Starting with a modest donation of 0.02 BTC, Fernando and his team have built a thriving ecosystem:
- Over 40 businesses now accept Bitcoin, ranging from souvenir shops and tour operators to beach vendors.
- Local students have received Bitcoin-loaded tap-to-pay, Bolt Cards, to use in their daily lives.
- Creative initiatives like “Bitcoin Banana Day” or "Frutas por Sats" (fruits for sats) where children buy fruits for 10 satoshis at school, have brought global attention to the project.
Praia Bitcoin’s success isn’t just about the adoption numbers, it’s about the stories. Families use Bitcoin to shop, business owners save on transaction fees, and children are learning the value of sound money at an early age.
LNbits - The Technology Behind Praia Bitcoin
Creating an economy on Bitcoin’s Lightning Network requires more than enthusiasm, it needs robust tools that are easy to use and adaptable to local needs. That’s where LNbits comes in.
Fernando and the Praia Bitcoin team have used LNbits’ open-source software to solve practical challenges and scale the project. With its modular design, LNbits provides tools that allow Praia Bitcoin to:
- Set Up Wallets: Community members receive user-friendly wallets that connect seamlessly to the Lightning Network, enabling fast, low-cost transactions.
- Issue BoltCards: Using LNbits’ BoltCard extension, the team has distributed NFC-enabled cards, allowing tap-to-pay functionality that makes Bitcoin payments as simple as using a credit card.
- Enable Flexible Payments: The project utilizes LNbits’ Point of Sale TPoS extension that allows merchants to easily receive Lightning Network payments.
Breaking Records, Building Community
Fernando doesn’t just implement solutions, he pushes boundaries. One of his most remarkable achievements was an attempt to set a world record for the most Lightning Network payments in the shortest amount of time. Over the course of one afternoon, 100 children in Jericoacoara received payments of 21,000 satoshis each, demonstrating the scalability and speed of Lightning-powered transactions.
This wasn’t just a technical feat, it was a community moment. The event showed how Bitcoin could serve as a tool for engagement, education, and empowerment, all while highlighting the possibilities of using the Lightning Network for real-world applications.
A Collaborative Approach to Innovation
One of the unique strengths of LNbits is its ability to evolve based on community feedback. While Fernando Motolese and Praia Bitcoin operate independently, their insights have helped refine the LNbits platform.
For example, Fernando’s need for a PIN-less ATM functionality led the LNbits team to implement that feature in the TPoS extension, that had the functionality but required a security PIN. This kind of collaboration isn’t about formal partnerships. It’s about how an open-source ecosystem thrives when real-world needs drive innovation.
The feedback loop between users like Fernando and developers ensures LNbits remains practical and relevant—not just for Praia Bitcoin but for countless other projects worldwide.
The Ripple Effect of Praia Bitcoin
Praia Bitcoin is a case study in what’s possible when Bitcoin meets a strong vision. By leveraging Bitcoin, the Lightning Network and LNbits, the project has redefined financial access in Jericoacoara, proving that small communities can lead big innovations.
For LNbits, Praia Bitcoin showcases the value of adaptable, open-source solutions. Whether it’s creating wallets, enabling NFC payments, or refining tools for real-world use, LNbits provides the infrastructure that makes projects like Praia Bitcoin possible.
But beyond the technical achievements, Praia Bitcoin reminds us of the human impact of Bitcoin adoption. It’s about children buying their first bananas with satoshis, families running businesses with lower fees, and a community connecting to a global financial network for the first time.
Conclusion
Praia Bitcoin’s journey is only getting started and its success is inspiring similar initiatives worldwide. For LNbits, being part of this story, is a testament to the power of the software and of open-source collaboration.
If you’re ready to build the future of Bitcoin adoption, LNbits offers the tools to turn ideas into impact.

2025-04-29 09:19:05A professional financial advisor can guide you to achieve long-term financial stability. They can assist you to define your goals to formulate strategic planning coupled with rational decision-making. Since the options are varied and multiple, how can you go about choosing a fiduciary financial advisor whose approach matches their financial goals? This guide explains exactly how to pick a financial advisor who suits your individual financial targets.
Defining Your Financial Needs and Goals
You need to specify your financial aspirations as well as your essential requirements so an advisor can create a suitable plan for your portfolio. Starters should establish their monetary targets before initiating contact with financial consultants. Any objective requires planning such as retirement preparation and investment management and education savings along with wealth protection and growth needs to be identified. Knowing your financial goals helps you determine if an advisor’s experience matches the needs of reaching your targets. Before you conduct meetings with possible financial advisors you need to have clearly established financial goals which will make these meetings goal-focused and beneficial.
Trusted financial advisors at Passive Capital Management can help you check out financial plan tailored to your needs and goals.
Look For Professional Credentials and Qualifications
Review carefully the advisor’s qualifications after you establish your goals. The strict training and ethical assessments that CFP Certified Financial Planner and the CFA Chartered Financial Analyst professionals demonstrate their professionalism. The designations set by these organizations prove advisors maintain knowledge in planning, investments and regulatory requirements. It is essential to verify that the advisor operates under fiduciary standards since this legal requirement ensures they must always act according to your benefit. It is essential to verify if an advisor functions as a fiduciary all the time because some only act under specified circumstances. Get a direct and unambiguous statement about their status. Under fiduciary relationships your financial security stands as the main priority of your financial advisor while fiduciary arrangements reduce potential conflicts between your interests.
Understand the Advisor’s Investment Approach
While consulting an advisor, you might encounter several hidden conflicts of interest. So a robust advisor-client connection based on their mutual investment approach including strategy selection is essential. Review the risk approaches of your advisor through inquiries to learn about their portfolio design strategies and market investment strategies. Technical competence must be combined with an awareness of your risk tolerance and time preferences according to their responses. A reliable advisor will adapt their investment methods to match the risk tolerance of their client combined with their financial destination.
Review their Service Package and Communication Style
A competent financial advisor functions past standard investment management duties. Their service range needs to include full-scale financial planning in areas such as retirement income strategies along with tax and estate planning solutions and insurance assessments. Check that their service suite matches your financial development needs. The advisor needs to maintain both clear and predictable ways of communication. Reveal their review process schedule and disclosure methods for reporting metrics as well as their availability to respond to questions at any time during the year. Professional communication builds reliable relationships that involve active participant commitment in planning activities.
Clarify the Fee Structure
Knowing how your advisor gets paid gives you the essential knowledge needed for building trust between you both. Financial advisors conduct business through payment structures which include flat fees, percentage-based fees on managed assets and extra earnings from their advisory products. The different compensation models bring their own effects and outcomes to the process. The most significant aspect for you is receiving clear explanations about fees while they are in alignment with your financial planning. The first practice of transparent communication by an advisor suggests they will uphold that approach during your entire time together.
Conclusion
Alongside numerical expertise your ideal advisor should function as a trustworthy partner because they will dedicate themselves to your financial growth. Strategic decision-making depends on the establishment of clear objectives and verification of expertise as well as confirmation of fiduciary principles and comprehensive evaluation of communication methods and associated fees. Your financial destiny requires organized assessment along with expert consulting while the correct professional consultant enables you to move through every phase of your path with obvious direction and solid self-assurance.

2025-04-29 08:47:56A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:
“I just feel like I’m so behind.”
Behind who? Behind what?
There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.
Where did this come from?
Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.
But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.
Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.
I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.
“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?
If you need a permission slip to stop comparing, let this be it.
You’re not late. You’re not early.
You’re right on time. -

2025-04-29 08:26:50With the advancement of quantum computers, a new threat emerges for the security of cryptocurrencies and blockchain technologies. These powerful machines have the potential to expose vulnerabilities in traditional cryptographic systems, which could jeopardize the safety of digital wallets. But don’t worry—modern wallets are already equipped to handle this threat with innovative solutions that make your funds nearly impossible to steal, even by a quantum computer. Let’s explore how this works and why you can rest easy.
The Threat of Quantum Computers
To understand how wallets protect us, we first need to grasp what makes quantum computers so dangerous. At the core of most cryptocurrencies, like Bitcoin, lies public and private key cryptography. The public key (or address) is like your bank account number—you share it to receive funds. The private key is like your PIN—it allows you to send funds and must remain secret.
Traditional cryptography, such as the ECDSA algorithm, relies on mathematical problems that are extremely difficult to solve with conventional computers. For instance, deriving a private key from a public key is practically impossible, as it would take millions of years of computation. However, quantum computers, thanks to algorithms like Shor’s, can significantly speed up this process. Theoretically, a sufficiently powerful quantum computer could uncover a private key from a public key in minutes or even seconds.
This is a problem because if someone gains access to your private key, they can send all your funds to their own address. But here’s the good news—modern wallets use a clever solution to render this threat powerless.
How Do Wallets Protect Us?
One of the most effective defenses against quantum computers is the use of one-time addresses in wallets. This means that for every transaction—whether receiving or sending funds—the wallet automatically generates a new public address. The old address, once used, remains in the transaction history but no longer holds any funds, as they are transferred to a new address.
Why Does This Work?
Imagine you’re sending or receiving cryptocurrency. Your wallet creates a new address for that transaction. After the funds are sent or received, that address becomes “used,” and the wallet automatically generates a new one for the next transaction. If a quantum computer manages to derive the private key from the public address of the used address, it will find nothing—because that address is already empty. Your funds are safely transferred to a new address, whose public key has not yet been exposed.
This strategy is known as HD (Hierarchical Deterministic) wallets. It allows the wallet to generate an infinite number of addresses from a single master key (seed) without compromising security. Each new address is unique and cannot be linked to the previous ones, making it impossible to trace your funds, even with a quantum computer.
Automation Makes It Effortless
The best part? You don’t need to worry about this process—it’s fully automated. When you use a modern wallet like MetaMask, Ledger, Trezor, or software wallets for Bitcoin, everything happens behind the scenes. You simply click “receive” or “send,” and the wallet takes care of generating new addresses. There’s no need to understand the complex technical details or manually manage your keys.
For example:
- You want to receive 0.1 BTC. Your wallet provides a new address, which you share with the sender.
- After receiving the funds, the wallet automatically prepares a new address for the next transaction.
- If you send some of the funds, the remaining amount (known as “change”) is sent to another new address generated by the wallet.
This system ensures that public addresses exposed on the blockchain no longer hold funds, making quantum attacks pointless.
Additional Protection: Toward Post-Quantum Cryptography
Beyond one-time addresses, blockchain developers are also working on post-quantum cryptography—algorithms that are resistant to quantum computers. Some blockchain networks are already experimenting with such solutions, like algorithms based on lattices (lattice-based cryptography). These methods don’t rely on the same mathematical problems that quantum computers can solve, offering long-term protection.
In the meantime, one-time addresses combined with current cryptographic standards provide enough security to safeguard your funds until post-quantum solutions become widely adopted.
Why You Shouldn’t Worry
Modern wallets are designed with the future in mind. They not only protect against today’s threats but also anticipate future risks, such as those posed by quantum computers. One-time addresses make exposed public keys useless to hackers, and automation ensures you don’t need to deal with the technicalities. HD wallets, which automatically generate new addresses, make the process seamless and secure for users.
Public key exposure only happens when necessary, reducing the risk of attacks, even from a quantum computer. In conclusion, while quantum computers pose a potential threat, modern wallets already offer effective solutions that make your cryptocurrencies nearly impossible to steal. With one-time addresses and the upcoming adoption of post-quantum cryptography, you can be confident that your funds are safe—today and tomorrow.

2025-04-29 08:20:58Die Satire Muxmäuchenstill von 2004 erzählt die Geschichte des 30-jährigen Mux, der seine Mitbürgern zu mehr Verantwortungsbewusstsein erziehen möchte. Dazu stellt er Raser, Schwarzfahrer, Graffiti-Sprüher, Falschparker, Ladendiebe und Vergewaltiger, konfrontiert sie mit ihrem Verhalten und bestraft sie.
https://soundcloud.com/radiomuenchen/muxmauschenstill-x-interview-mit-jan-henrik-stahlberg?
Als Mitstreiter gewinnt er Arbeits- und Obdachlose. Mux’ fanatische Ein-Mann-Mission wächst zu einem kleinen Unternehmen. Auch privat kann er seinen Moralismus nicht zügeln und erschießt seine Freundin. Am Ende des Films wird er von einem Raser überfahren.
Ab 1. Mai läuft die Fortsetzung in den Kinos: Muxmäuschenstill X: muxfilm.de/. Nach zwanzig Jahre Wachkoma findet sich Mux in einer Welt wieder, die er nicht mehr versteht: dem wunderbaren Neoliberalismus. Wieder möchte Mux die Menschen erziehen. Doch diesmal kämpft er gegen ein System, das alles durchdringt, die Welt spaltet, unsere Lebensgrundlagen zerstört, die Reichen reicher macht und die Armen ärmer. Mux gründet den Muxismus und schart die Aussortierten des Systems um sich.
Drehbuchautor und Hauptdarsteller Jan Henrik Stahlberg führt diesmal auch Regie. Unser Autor Jonny Rieder hat mit Jan Henrik Stahlberg über seinen neuen Film gesprochen. Zunächst wollte er wissen, wo für ihn die Grenze verläuft zwischen Übergriffigkeit und Zivilcourage und wie er Mux hier einordnet.

"Show me the incentives, and I'll show you the outcome"[^mungerquote].
"Even bacteria respond to motivation." ~[^dufrene2020][^amoedo2024].
Introduction
In Austrian economics, time preference refers to the value individuals place on present consumption versus future consumption [^rothbard1993man]. A society with a lower time preference is more inclined to save, invest, and plan for the long term, thereby fostering progress and stability [^ammous2018]. In contrast, a society with a higher time preference tends toward immediate consumption rather than investment — or invests without a true understanding of its purpose — leading to short-term planning and a gradual drift from foundational societal values, traditions, and culture [^hoppe2001].
The definition of investment is the process of allocating resources to productive activities, prioritizing future gains over immediate consumption. It involves capital accumulation and is key to economic growth, as individuals delay gratification to increase future value. This approach underlies capital formation and enhances an economy's production capacity, aligning with lower time preference and fostering long-term prosperity [^mises1998].
With a foundational understanding of time preference and investment, we can begin to examine what motivates people today. Given the prevalence of high time preference in modern society, the government can capitalize on this tendency by offering immediate handouts and benefits, satisfying the population's desire for instant gratification, often at the expense of long-term prosperity and future gains. This tendency is also mirrored in mainstream media, where a focus on sensational, attention-grabbing stories diverts focus from deeper, structural issues. By amplifying polarizing narratives [^gentzkow2006media], often tied to social identity or lifestyle differences, the government and media create a cycle of constant engagement and distraction, steering public attention towards short-term controversies and away from underlying economic or social policy issues [^caplan2001rational].
Debt & Fractional-Reserve Banking
A common denominator that repeatedly emerges in such destructive behavior promoted by governments is the issue of money. As money drives the world, understanding and following its flow not only reveals how it operates but also uncovers those who wield control over it, and how human behavior is driven by it.
Money is a broad term encircling all assets that can be used for exchange, storage, and valuation, covering both physical and digital forms [^ammous2023]. Cash is a subset of money, referring specifically to physical currency, such as coins and notes.
The process of money creation, typically managed by governments and central banks, is the foundation of economic dependency within the financial system. In most economies, central banks control currency creation through mechanisms like open market operations and debt. For instance, when a central bank, such as the Federal Reserve, issues new currency, it does so by purchasing government securities from commercial banks, thus adding currency to the economy. However, this transaction is not debt-free; it obliges the government to repay the borrowed amount with interest.
In common words, the process of creating money is as follows: the government request to the central bank a certain amount of money to be printed in borrowing form. The central bank then creates that money, out of thin air, on the promise that the government will repay the central bank down the road. Since the government does not produce anything, in order to repay the central bank, the government then sells the debt via bonds to anyone who would like to buy the government debt. In even more simple words: the government and central bank creates money out of thin air based on debt [^ammous2021].
The issue with money creation is not only by the fact that it was created out of thin air, but because money creation has other issues tied to it: the debt, the creation of fractional-reserve monetary system, inflation, and interest.
This foundational reliance on debt, since it is present in the very beginning of money creation, renders the entire monetary system debt-dependent. Therefore, saving and investing within such a system becomes questionable, as the system's nature opposes the principles of sustainable wealth accumulation, thus leading human behavior not to save but to spend.
A fractional-reserve monetary system is a banking structure in which banks retain only a small fraction of their depositors' funds — historically around 10%, but today often as low as 1% [^bundesbank2024] — while lending out or investing the remainder. This setup allows banks to expand the money supply and stimulate economic activity through a process known as deposit expansion [^federalreserve1975modern]. Deposit expansion occurs when banks effectively treat a portion of deposited funds as new money, multiplying the original deposit base. For example, if a bank holds deposits totaling 1 million euros, it can lend out up to 1.9 million euros, as long as it maintains 10% of the initial deposit in reserve. This cycle can repeat, enabling banks to increase the total money supply to infinity, but the "Modern Money Mechanics: A Workbook on Bank Reserves and Deposit Expansion" and government applying it recommends not doing it above 9 times the original deposit value [^federalreserve1975modern].
To make matters worse, inflation and interest exacerbate the problems inherent in this monetary system. Interest is a foundational element of the system, initially intended to address the original debt incurred by the government. In economic terms, interest represents the "price" of time preference, a premium placed on present goods over future goods. To illustrate the impact of interest, consider the cost of a house in today's system: a house priced at 500,000 euros with a 4% variable interest rate ends up costing around 860,000 euros over 30 years, with 360,000 euros paid in interest alone.
Inflation, on the other hand, is the increase in the money supply — money printing — and can only be truly calculated by M2[^1] money supply metric. Inflation erodes the value of both assets and earned income, as each new unit of currency devalues existing money. This devaluation impacts not only the purchasing power of savings but also the real cost of goods and services over time, reducing the long-term value of assets people believe they own.
The government
Operating within a monetary system stretched beyond its limitations, the government faces the dual challenges of controlling inflation and satisfying its growing spending demands. To fund its expenditures, the government often provides public benefits — subsidies, "free" healthcare, public transport, security, military, and welfare in general — to justify continual spending and cultivate public support - via voting, in most democratic countries.
Welfare and most government programs redistribute wealth from producers to non-producers, fostering dependency on the state. Over time, this erodes individual sovereignty and expands government control, restricting freedom, and reducing people to slaves or cash cows.
The government justifies taxes as payment for welfare and public services, but also claims they curb inflation by reducing the need to print money. The logic is that by reclaiming taxpayer money, the money supply is controlled. However, this is misleading, especially when the government can print money at will, making taxation on such currency inherently flawed.
Taxes are extracted via coercion - violence - by the government onto the population. The government then decides where to allocate this money, based on their guess of what the population needs, excluding private preferences. Therefore, taxes are not an incentive to accumulate, not even to work more. Taxes are an incentive to do right the opposite: do not save and do not work more.
Another tactic the government employs is to create crises that it alone can "solve", thus requiring more taxes or funding. Recent examples include crises like COVID-19, the "green" agenda, and initiatives to combat climate change[^2]. In each case, the government presents itself as the sole solution, yet solving these crises inevitably demands additional resources — in the form of increased taxation.
Even minimal critical thinking would prompt one to question the true necessity of taxes in a government that owns and controls the money printer. Given what we now understand, if you were in the government's position, would you willingly relinquish control of money creation by tying it to something like gold, empowering people to become smarter, independent, and wealthy?
The government, through various channels — media, education, propaganda, welfare, and government subsidies — ensures that people remain obedient and uninformed. It keeps them financially constrained by increasing taxes and imposing extensive regulations, while fostering dependency through handouts, welfare, and other social programs. The government is the only entity that, by law, can use violence and coercion without prosecution [^rothbard2009].
"Anyone who, although human, is by nature not yours but someone else's"[^ambler1987].
It is therefore unsurprising that many live in a state akin to enslavement, reflecting a mindset shaped by constant dependency. It is no wonder that people are discouraged from having children, as they can barely support themselves. Nor is it surprising that individuals might question the need to continue their bloodline, believing in the illusory value of "fake money" [^kiyosaki2019] and trusting present "investments" and the government to provide a pension in old age. And it's certainly not surprising to see people asking the government for solutions to every problem, when the government leaves them no viable alternatives.
"Show me the incentives, and I'll show you the outcome"[^mungerquote].
That statement serves as a powerful tool for understanding and addressing complex issues. When observing behaviors that may appear unusual — such as individuals identifying as "trans-species," a phenomenon linked to mental health concerns [^pinna2022] — it's essential to consider the underlying incentives. Who benefits most from a society in which individuals remain financially constrained, dependent, and uninformed? A fiat-based monetary system functions as a modern form of economic control, keeping people poor by design. Taxes, effectively a penalty for productivity, contrast sharply with welfare programs, which often reward dependency and reinforce reliance on the government. Meanwhile, government narratives and selective information shape public beliefs, protecting institutional interests and discouraging critical inquiry[^3].
Conclusion
Like the fungus that infects in parasitic way an ant's nervous system - Ophiocordyceps Unilateralis -, rendering it a zombie [^britannica2024] controlled by an external force, similarly, modern bureaucracies exploit the mechanisms of fiat money, debt, and taxation [^rothbard2009] to maintain control over individuals, steering them away from self-reliance and critical thinking toward a state of perpetual dependence.
The parallels are striking: just as the fungus manipulates the ant's behavior to secure its reproduction, governments manipulate public perception, creating crises, shaping incentives, and fostering dependence[^rothbard2009] through welfare programs[^caplan2001rational], inflated debt[^ammous2018], and coercive taxation. These mechanisms suppress individuality, reduce productivity, and shift power further into centralized hands[^gentzkow2006media], leaving citizens "zombified", detached from purpose and independence.
"Even bacteria respond to motivation."[^dufrene2020]
If tolerated — even by you, dear reader — this parasitic cycle will continue to erode humanity's dignity and potential. The solution lies in reclaiming agency by building a society grounded in sound money, meaningful productivity, and spiritual and cultural foundations that connect us to higher purposes. As warned in Jeremiah 17:5 [^4], trusting fallible human systems leads to enslavement. True freedom comes from rejecting exploitative bureaucracies and embracing systems aligned with truth, autonomy, and resilience.
Another way is to fully understand the system and opt out. This requires mastering the rules and using them to your advantage. If legal avenues exist to avoid taxation, expropriation, eminent domain, or government coercion, then the first step is to change the game for yourself.
The monetary system and government incentives shape human behavior, influencing those who allow themselves to be controlled by them.

Footnote
[^1]: M2 refers to savings deposits + money market mutual funds + small time deposits. M2 includes all of M1 plus "near money" (M0), which consists of savings deposits, money market accounts, and small-denomination time deposits (like certificates of deposit under a certain amount). M2 is commonly tracked by central banks to gauge medium-term economic activity and savings behavior, as it includes money that people save rather than spend immediately.
[^2]: Since the 1990s, societies worldwide have been confronted by a series of global crises, often framed as urgent and overwhelming challenges. All scams. Including deforestation, ocean and air pollution, nuclear waste, oil spills, plastic and soil pollution, drought, fossil fuel consumption, rising sea levels, species extinction, extreme weather, global warming, melting glaciers, acid rain, and, recently, climate change. Each crisis has shaped public opinion and policy, and also created new laws, regulations, and taxes.

Because of a fortuitous set of circumstances, we had access to a sample of men convicted of crimes against humanity (CAH) committed during the Pinochet regime, each rated by expert clinicians on the Psychopathy Checklist-Revised (PCL-R). We also had PCL-R ratings for samples of general offenders and community participants. Methods We determined the psychometric properties of the PCL-R for these samples, performed structural equation modeling (SEM) to investigate the factor structure of the PCL-R, and conducted a latent profile analysis (LPA) of the obtained factors to identify classes or subtypes within the samples. Results The PCL-R's psychometric properties and factor structure were in accord with findings from other countries and settings. The PCL-R total scores of the CAH and general offenders were virtually the same but much higher than those of the community sample. However, the CAH group had extraordinarily high scores on the Interpersonal/Affective facets yet relatively low scores on the Lifestyle/Antisocial facets. LPA identified the expected four latent classes, with most CAH men located within the Callous-Conning class. Conclusions The results of this study provide unique information about the psychopathic propensities of a sample of state violators of human rights. Their pattern of PCL-R scores was consistent with an extreme disposition for self-serving, callous, and ruthless treatment of others, without guilt or remorse, and in the absence of a prior documented history of severe antisocial behavior.} } @misc{klaas2023, author = "{Brian Klaas}", title = "{{How many politicians are psychopaths?}}", howpublished = {\url{https://www.forkingpaths.co/p/how-many-politicians-are-psychopaths}}, note = {Online; accessed 29 January 2024}, year=2023 } @article{pinna2022, title={Mental health in transgender individuals: a systematic review}, author={Pinna, Federica and Paribello, Pasquale and Somaini, Giulia and Corona, Alice and Ventriglio, Antonio and Corrias, Carolina and Frau, Ilaria and Murgia, Roberto and El Kacemi, Sabrina and Galeazzi, Gian Maria and others}, journal={International Review of Psychiatry}, volume={34}, number={3-4}, pages={292--359}, year={2022}, publisher={Taylor \& Francis}, doi={10.1080/09540261.2022.2093629}, url={https://pubmed.ncbi.nlm.nih.gov/36151828/} } @book{rothbard2009, title={Anatomy of the State}, author={Rothbard, Murray}, year={2009}, publisher={Ludwig von Mises Institute} } @misc{britannica2024, author = {{Encyclopaedia Britannica}}, title = {Zombie-Ant Fungus}, year = {n.d.}, url = {https://www.britannica.com/science/zombie-ant-fungus}, note = {Accessed: 2024-11-07} } @misc{amoedo2024, author = {Renato Amoedo}, title = {Até as bactérias respondem a uma motivação}, year = {2024}, note = {Famosa frase mencionada em entrevistas e podcasts relacionados a comportamento e motivação}, howpublished = {Comentário público}, } @article{dufrene2020, title={Mechanomicrobiology: how bacteria sense and respond to forces}, author={Dufrêne, Yves F. and Persat, Alexandre}, journal={Nature Reviews Microbiology}, volume={18}, pages={227--240}, year={2020}, month={April}, doi={10.1038/s41579-019-0314-2}, url={https://doi.org/10.1038/s41579-019-0314-2}, publisher={Springer Nature}, note={Accepted 06 December 2019, Published 20 January 2020} } @misc{mungerquote, author = {Munger, Charlie}, title = {Show me the incentive and I will show you the outcome}, note = {Often attributed to Charlie Munger, known for his wisdom on finance and life as Warren Buffett's business partner.}, howpublished = {Quote}, year = {n.d.}, url = {https://elevatesociety.com/quotes-by-charlie-munger/} }

2025-04-29 07:59:37Solar Power Tips for a Sustainable Remote Home Office
As more professionals transition to remote work, the need for sustainable and cost-effective solutions has never been greater. One of the most effective ways to reduce your ecological impact and lower energy costs is by harnessing the sun's power—specifically, solar energy.
Solar power is becoming increasingly popular among remote workers, providing a renewable energy source for residences with a home office setup. It helps reduce reliance on fossil fuels, and offers the potential for significant long-term savings.
This blog will list the benefits of using solar power in a remote home office environment. Whether you want to reduce your carbon footprint or reduce your energy expenses, the information will guide you in creating a more sustainable design for a productive home office. Choosing the Right Solar Panels Building a solar-powered home office starts with picking the right solar panels. You can choose from traditional photovoltaic panels to sleek solar shingles that blend with your roof's design.
Recent advancements in solar technology have introduced more compact and efficient panels, making it easier than ever to generate significant power, even in smaller spaces.
When choosing solar panels, prioritize efficiency ratings and durability. High-efficiency panels, such as monocrystalline options, can produce more energy with less surface area. They are ideal if you have limited roof space.
Aesthetics can also play a role, particularly if you want your home office to maintain a modern, professional appearance. For example, solar shingles offer a subtler alternative to standard panels while providing comparable energy production. Essential solar power components Setting up a fully functional solar-powered home office requires more than just panels. Below are the essential components to consider:
Inverters
Solar panels create direct current (DC), but most home appliances run on alternating current (AC). Inverters convert DC to AC, so you can use solar power. Look for high-quality inverters, such as micro-inverters, which optimize the output of each panel individually.
Batteries
Energy storage is critical because solar power is not always available. Solar batteries let you save extra energy made during the day so you can use it at night or when it is cloudy. Consider opting for lithium-ion batteries due to their high energy density, long lifespan, and relatively small size.
Mounting hardware
Proper installation is key to getting the most energy from your solar panels and making sure they can handle tough weather. Adjustable mounts let you place your panels to get the most sunlight and ensure they last over time. Benefits of Solar Power in a Home Office You may wonder: why is solar power for a home office such a big deal? Here are the reasons why: Cost savings and environmental impact One of the biggest benefits of using solar power in your home office is the potential to save a lot of money. Making your electricity can help you reduce or even eliminate your monthly energy bills.
The average owner can save between $10,000 and $30,000 over the lifespan of a solar energy system, depending on their location and system size. Plus, federal tax credits, state incentives, and net metering programs can lower both the initial and ongoing costs of going solar. Reliability and independence Solar power also provides unmatched reliability and independence, particularly in areas prone to power outages. Coupling your solar panels with a high-capacity battery storage system allows you to maintain power for essential devices during power cuts.
It becomes a critical advantage if you need to keep your computers, internet, and other tools working to stay productive.
Solar energy also frees you from relying on the power grid, which is especially helpful if you live in rural or remote areas where power may be less reliable or more expensive. Additional Tips for a Sustainable Home Office Maximize your home office with these practical ways: Complementary green technologies Consider incorporating complementary green technologies into your home office, such as:
Smart thermostats
Devices like the Nest or Ecobee learn your habits and adjust the temperature to maximize comfort while minimizing energy usage. A smart thermostat regulates heating and cooling based on your schedule, significantly reducing your energy use and costs.
Energy monitors
Tools like the Sense Home Energy Monitor help track energy usage across your home. You can identify energy-draining devices to make better decisions about allocating and conserving power and optimizing your solar system's efficiency.
LED lighting
Transitioning to LED bulbs uses less energy and makes your lights last longer. They further lower replacement costs and waste. Outdoor solar solutions Sustainability does not have to stop at your office door. The following outdoor solar-powered devices can enhance the eco-friendliness of your entire home environment:
Solar-powered garden lights
These lights use built-in solar panels to charge during the day and illuminate your outdoor spaces at night. They are perfect for adding ambiance to your yard or improving visibility along pathways without increasing your electricity bill.
Solar security cameras
Protect your property with solar-powered security cameras. They are self-sufficient and eliminate the need for extensive wiring.
Solar water features
From fountains to birdbaths, solar-powered water features add aesthetic appeal to your garden while relying entirely on renewable energy. Shine Bright at Home Embracing solar power for your home office is a smart step toward a greener, more cost-effective future. Choosing efficient solar panels, integrating essential components like inverters and batteries, and pairing them with complementary green technologies can help you create a sustainable workspace that aligns with modern, eco-conscious values.
If you're considering finding a home in Laguna, Philippines, solar energy becomes an even more valuable investment. With Laguna’s growing residential developments, eco-friendly communities, and abundant sunlight, homeowners can take full advantage of renewable energy to lower electricity costs and reduce their carbon footprint. Many new housing projects in Laguna also emphasize sustainability, making it easier to integrate solar solutions into your home.
Investing in solar power is more than a commitment to the environment—it is a long-term strategy for saving money and boosting reliability in your day-to-day work life. With these tips, you are well on your way to creating a home office that works as hard for the planet as you do.

Russische Hobby-Flieger konnten mit ihrem Sportflugzeug namens "Andromeda" unter dem Radar bleiben und haben entlang der Hauptstromtrassen mit einem ukrainischen Zwiebelmesser die Stromleitungen gekappt. In einer scharfen Rechtskurve muss wohl eine Flugzeugtür aufgegangen sein und der Pass des Piloten fiel unbemerkt heraus. Die Identität der Täter konnte so schnell festgestellt werden.
28.04.2025, 16.43 Uhr:
Trump hat das europäische Stromnetz gekauft und die in den Umspannwerken eingebauten US-amerikanischen Chips deaktiviert. Es gibt erst wieder Strom, wenn sich die Koalition der Willigen den Friedensverhandlungen für die Ukraine anschließt. Trump hat bewusst in den sonnenreichen Ländern Spanien und Portugal begonnen, das soll als Warnung für ganz Europa gelten. Frau von der Leyen hat bereits scharfen Protest eingelegt, doch Trump hat die SMS sofort gelöscht.
28.04.2025, 17.12 Uhr:
Selensky hat einen Cyber-Angriff auf das europäische Stromnetz gestartet. Er ist wütend, weil sich Macron in dem 15-Minuten-Gespräch mit Trump am Rande der Beerdigung des Papstes in Rom hat abwimmeln lassen. Er beendet die Strom-Blockade erst, wenn Spanien, Portugal und Frankreich Deutschland dazu zwingen, endlich Taurus zu liefern. Auf die Frage, wie Selensky das angestellt hat, soll er geantwortet haben: "Sie sehen ja, wir können es."
Ist natürlich alles nur Joke! Es sollte nur einmal in Bezug auf die Sprengung der Nordstream 2 Pipelines aufgezeigt werden, wie schnell auch unsereins abstruse Erklärungen liefern kann, die vorne und hinten nicht stimmen können.

2025-04-29 07:21:54The application of chlorine in water treatment is mainly reflected in its ability to act as a disinfectant. It can effectively kill bacteria, viruses and other microorganisms in water, thereby reducing the risk of waterborne diseases. The following is a detailed description of the application of chlorine in water treatment:
Disinfection As an effective disinfectant, chlorine is usually added to water during the water treatment process in the form of chlorine gas, chlorophyll acid or chlorine. This process is called chlorination, which ensures that pathogens in the water are effectively eliminated. Chlorine's disinfection ability comes from its strong oxidizing properties, which can destroy the cell structure of microorganisms to achieve the purpose of disinfection.
Disinfection By-products Despite the obvious benefits of chlorine in disinfection, there are also some negative effects. Chlorine disinfection may lead to the formation of disinfection by-products such as chloroform and chloroform, which may pose potential health risks in high concentrations. Therefore, when using chlorine for water treatment, the chlorine content needs to be strictly controlled to ensure the safety of the water.
Chlorine Measurement and Control Monitoring and controlling the chlorine content in the water treatment process is very critical. Total chlorine is the total amount of all forms of chlorine in water, including free residual chlorine, combined residual chlorine and other forms of chlorine such as chlorinated hydrocarbons. Available chlorine refers specifically to the part of chlorine in water that has bactericidal ability, including free residual chlorine, some combined residual chlorine (such as monochromatic and diamorphine) and chlorine dioxide. The measurement of available chlorine is crucial for evaluating the disinfection effect of water.
In summary, the application of chlorine in water treatment is mainly as a disinfectant to kill pathogens in water through its strong oxidizing properties. However, the use of chlorine also needs to be cautious to avoid the generation of harmful disinfection by-products, and other safer disinfectants such as chlorine dioxide can be selected when necessary.

2025-04-29 06:23:10You don’t talk about it much — but you’re tired. Tired of pretending you're okay. Tired of giving your best and wondering if it’s even enough. Tired of being strong for everyone else while quietly falling apart.
But here's something you might not hear often: I’m proud of you.
Not because you’ve figured everything out — but because you haven’t given up. Even with the weight on your shoulders, you're still here. Still trying. Still hoping. Still holding on.
That counts. That matters. That’s strength too.
The truth is, progress doesn’t always look like big wins. Sometimes it’s just getting out of bed. Sometimes it’s choosing peace over proving a point. Sometimes it’s breathing through the pain and saying, “I’ll try again tomorrow.”
So if no one has told you lately: You’re doing better than you think. Rest if you need to. Cry if you must. But don’t stop. Because something beautiful is growing from everything you’re surviving.

Housed in a historic landmark on George Town’s atmospheric Lebuh Farquhar, just a stone’s throw from the iconic Eastern & Oriental Hotel, MOJO JOJO is a café and brunch spot by day, and a refined eatery come nightfall. With an effortlessly cool edge, the space has been designed by Empt Studio and combines contemporary charm with the energy of this Malaysian city.
Split into two sections, the venue caters to both hotel guests and passersby. One side offers an intimate, tailored dining experience for those seeking a respite from the buzz of outside, while the other spills out onto the street, embracing George Town’s lively buzz. The soaring ceilings create a sense of openness, further enhanced by the introduction of a mezzanine above the kitchen, maximising space without compromising on airiness.
Natural materials feature throughout with custom bamboo display systems and solid Nyatoh timber fixtures lending a rich, textural warmth. Deliberately crafted interlocking joints pay homage to traditional woodworking techniques, reinforcing both strength and authenticity. Every detail nods to meticulous craftsmanship, from the aged wood grains to the earthy material palette that echoes the heritage of its surroundings.
Lighting plays a supporting yet pivotal role, with carefully curated, softly diffused illumination accentuating the textures and forms within. The interplay of warm light and natural materials fosters an immersive, atmospheric retreat from the fast-paced city outside.
A refuge for slow mornings and, later on, offering a more cultured affair, MOJO JOJO is a debonair dining spot for the handsome Penang capital.

2025-04-29 05:23:45Hubless Wheels + Donut Motor brings manufacturing & performance benefits
Verge Next, a subsidiary of Estonia-based Verge Motorcycles, invented this Donut Motor. It's designed to drive a hubless wheel. Although once seen as something that simply looked cool in renderings, the company says the hubless arrangement brings performance and manufacturing benefits, "delivering unmatched torque and power density with minimal weight."
For one thing, there's no chain, belt or drivetrain required. Secondly, it frees the body of the bike from the task of holding the motor—everything is now contained within that rear wheel.
The company has not only incorporated the Donut Motor into their own bikes, but is now licensing the technology. Assuming it does what it says on the tin, our future streetscapes will be covered with hubless bikes, scooters and motorcycles.
Here's a closer look at a Verge bike and how its design is influenced by the motor:

2025-04-29 02:16:06เบื้องหลังการเปลี่ยนแปลงครั้งใหญ่ในประวัติศาสตร์ เราต้องเข้าใจปัจจัยที่เปลี่ยนแปลงตรรกะของความรุนแรง โดยเฉพาะปัจจัยเชิงมหภาค 4 ประเภทหลัก ได้แก่ ภูมิประเทศ ภูมิอากาศ จุลชีพ และเทคโนโลยี
- ภูมิประเทศ เป็นตัวกำหนดที่สำคัญมากต่อรูปแบบของรัฐและความสามารถในการควบคุมพลเมืองโดยเฉพาะเมื่อเปรียบระหว่างสภาพภูมิประเทศทางบกและทางทะเล พื้นที่ทะเลเปิดนั้นยากต่อการผูกขาดหรือควบคุม ทำให้กฎของรัฐไม่สามารถบังคับใช้ได้อย่างมีประสิทธิภาพ ต่างจากแผ่นดิน ซึ่งส่งผลต่อการจัดวางอำนาจอย่างลึกซึ้ง เมื่อเศรษฐกิจเริ่มเคลื่อนเข้าสู่โลกไซเบอร์ซึ่งมีลักษณะคล้ายทะเลเปิดมากกว่าภาคพื้นดิน รูปแบบของการปกครองและการใช้ความรุนแรงจึงมีแนวโน้มเปลี่ยนแปลงไปอย่างมีนัยสำคัญ ประวัติศาสตร์ก็สนับสนุนมุมมองนี้ รัฐยุคแรก ๆ มักเกิดขึ้นในพื้นที่ราบลุ่มชลประทานที่ล้อมรอบด้วยทะเลทราย เช่น เมโสโปเตเมียและอียิปต์ ซึ่งทำให้ประชาชนจำเป็นต้องพึ่งพารัฐที่สามารถควบคุมแหล่งน้ำเพื่อดำรงชีวิตได้ ก่อให้เกิดระบบเผด็จการที่มั่นคง ขณะที่ภูมิประเทศที่กระจายอำนาจ เช่น กรีซโบราณ กลับเอื้อต่อการเกิดประชาธิปไตย เพราะผู้คนสามารถพึ่งตนเองได้มากกว่า มีอิสระในการค้าขายทางทะเล และเข้าถึงรายได้ที่นำไปแลกกับอำนาจทางทหารและการเมืองได้
- ภูมิอากาศก็มีบทบาทไม่แพ้กันในการกำหนดกรอบของอำนาจทางการเมือง เช่น หลังสิ้นยุคน้ำแข็งราว 13,000 ปีก่อน ความเปลี่ยนแปลงของระบบนิเวศทำให้ทุ่งหญ้าเลี้ยงสัตว์ลดลง และป่าทึบเข้ามาแทนที่ ทำให้มนุษย์ต้องเปลี่ยนวิถีชีวิตจากนักล่ามาเป็นเกษตรกรอย่างหลีกเลี่ยงไม่ได้ การเปลี่ยนแปลงนี้ไม่ได้เกิดขึ้นเพราะความสมัครใจ แต่เพราะสิ่งแวดล้อมบีบบังคับ ภูมิอากาศยังมีอิทธิพลต่อเสถียรภาพทางเศรษฐกิจและการเมืองอย่างชัดเจน เช่น ศตวรรษที่ 17 ซึ่งเป็นยุคหนาวเย็นที่สุดช่วงหนึ่งในประวัติศาสตร์ ทำให้เกิดวิกฤตอาหารและความอดอยากทั่วโลก นำไปสู่การก่อกบฏและการปฏิวัติในหลายประเทศ
- จุลชีพ ก็มีบทบาทในเชิงการเมืองมหภาคอย่างลึกซึ้ง การล่มสลายของประชากรพื้นเมืองในทวีปอเมริกาจากโรคที่ชาวยุโรปนำเข้า เช่น หัด หรือไข้ทรพิษ ทำให้ยุโรปสามารถยึดครองดินแดนเหล่านั้นได้อย่างง่ายดาย แม้ในบางครั้งจะยังไม่ได้ลงจากเรือด้วยซ้ำ ในอีกด้านหนึ่ง จุลชีพก็เคยเป็นกำแพงที่ป้องกันไม่ให้จักรวรรดิยุโรปขยายอำนาจ เช่น มาลาเรียในแอฟริกาที่เคยทำให้พื้นที่เหล่านั้น “ต่อต้านอำนาจจากภายนอก” ได้อย่างนานหลายศตวรรษ
- เทคโนโลยี ซึ่งเป็นปัจจัยที่ที่ทรงอิทธิพลที่สุดต่อการเปลี่ยนแปลงของโครงสร้างอำนาจในประวัติศาสตร์มนุษย์ เพราะมันสามารถเปลี่ยน “ต้นทุน” และ “ผลตอบแทน” ของการใช้ความรุนแรงได้อย่างรวดเร็วและชัดเจน ทั้งในแง่ของอาณาเขต ขนาดของรัฐ ลักษณะของสงคราม และแม้แต่ความชอบธรรมทางการเมือง ผู้เขียนได้แยกอิทธิพลของเทคโนโลยีออกเป็น 5 มิติหลัก ซึ่งล้วนมีบทบาทอย่างสำคัญในการจัดรูปแบบของอำนาจ ได้แก่:
A. ดุลยภาพระหว่างการโจมตีและการป้องกัน เทคโนโลยีแต่ละยุคมีผลอย่างมากต่อความได้เปรียบระหว่างฝ่ายรุกกับฝ่ายรับ หากเทคโนโลยีในยุคนั้นเอื้อต่อ “การโจมตี” (เช่น เครื่องยิงหิน, รถถัง, ระเบิดทางอากาศ) ต้นทุนของการขยายอำนาจจะต่ำลง รัฐหรือจักรวรรดิจะรวมศูนย์มากขึ้นเพราะสามารถควบคุมพื้นที่กว้างได้ด้วยกำลังที่มีประสิทธิภาพ แต่หากเทคโนโลยีเอื้อให้ “การป้องกัน” มีต้นทุนต่ำและได้เปรียบ (เช่น ปราสาทยุคกลาง, อาวุธต่อต้านอากาศยาน, การเข้ารหัสข้อมูลในโลกไซเบอร์) รัฐจะมีแนวโน้มกระจายตัว และอำนาจท้องถิ่นจะแข็งแกร่งขึ้น
B. ความเท่าเทียมกันทางทหารของพลเมือง เทคโนโลยีอาวุธยังเป็นตัวแปรสำคัญในการกำหนดว่า “พลเมืองธรรมดา” มีอำนาจเพียงใดในการเผชิญหน้ากับชนชั้นปกครอง ตัวอย่างที่ชัดเจนคือในยุคก่อนปฏิวัติดินปืน ชาวนาที่ถือแค่ส้อมหรือจอบไม่อาจต้านอัศวินติดเกราะได้ แต่เมื่อการใช้ปืนแพร่หลาย เส้นแบ่งระหว่างสามัญชนกับขุนนางก็เริ่มจางลง และเกิดการปฏิวัติทางสังคมตามมาในหลายพื้นที่
C. ขนาดขององค์กรที่จำเป็นต่อการใช้ความรุนแรง บางเทคโนโลยีต้องการระบบสนับสนุนขนาดใหญ่ เช่น เสบียง การสื่อสาร การขนส่ง และระบบการฝึกฝนที่ซับซ้อน ซึ่งหมายความว่าเฉพาะองค์กรที่มีทรัพยากรขนาดใหญ่เท่านั้นจึงสามารถใช้อำนาจอย่างมีประสิทธิภาพได้ ตัวอย่างเช่น สมัยสงครามโลก รัฐที่มีอุตสาหกรรมและสายส่งที่มั่นคงเท่านั้นจึงสามารถรบได้นาน
D. ขนาดของกิจกรรมทางเศรษฐกิจในการผลิต ขนาดของหน่วยเศรษฐกิจที่ “เหมาะสมที่สุด” ในการผลิตสินค้าและบริการก็เป็นตัวแปรทางเทคโนโลยีที่ส่งผลต่อโครงสร้างของรัฐ หากเศรษฐกิจจำเป็นต้องอาศัยตลาดขนาดใหญ่ พื้นที่กว้าง หรือระบบโลจิสติกส์ที่ซับซ้อน รัฐขนาดใหญ่จะมีข้อได้เปรียบ เช่น จักรวรรดิอังกฤษที่สามารถจัดระบบเศรษฐกิจข้ามทวีปได้ในศตวรรษที่ 19 แต่หากเทคโนโลยีเอื้อให้เศรษฐกิจท้องถิ่นมีความคล่องตัว สามารถผลิตแบบกระจาย (distributed production)ได้ รัฐขนาดใหญ่ก็จะมีประสิทธิภาพน้อยลง และอำนาจจะกระจายตัว
E. การกระจายของเทคโนโลยี หากเทคโนโลยีสามารถถูก “ผูกขาด” ได้โดยกลุ่มเล็ก ๆ เช่น การควบคุมแหล่งพลังงานนิวเคลียร์ หรือการพัฒนาอาวุธล้ำสมัย อำนาจจะกระจุกอยู่กับชนชั้นนำ แต่หากเทคโนโลยีแพร่กระจายได้อย่างกว้างขวาง เช่น การใช้ดินปืน แป้นพิมพ์ อำนาจก็จะสลายตัวไปยังประชาชนทั่วไป
เมื่อพิจารณาประวัติศาสตร์ในมุมของ “สิ่งที่เกิดขึ้นจริง” ควบคู่กับ “สิ่งที่อาจเกิดขึ้นได้” เราจะเริ่มตระหนักถึงบทบาทของโอกาสและความเปราะบางที่มักถูกมองข้าม โดยเฉพาะในกรณีของจุลชีพ แม้จะเป็นตัวแปรที่ทรงพลังในอดีต แต่กลับดูเหมือนว่ามันมีผลกระทบต่อโครงสร้างอำนาจในยุคใหม่ต่ำกว่าที่ควรจะเป็น ทั้งที่ในทางทฤษฎีแล้ว มันมีศักยภาพสูงยิ่งในการเปลี่ยนแปลงประวัติศาสตร์ หากเชื้อไวรัสสายพันธุ์ใหม่ที่ร้ายแรงและแพร่กระจายได้ง่าย เทียบเท่าหรือรุนแรงกว่ามาลาเรีย แพร่ระบาดในหมู่นักสำรวจโปรตุเกสช่วงต้นของยุคการเดินเรือ อาจไม่มีการสำรวจหรือขยายอาณานิคมเกิดขึ้นเลย เช่นเดียวกับหากโคลัมบัสและผู้ย้ายถิ่นกลุ่มแรกในโลกใหม่ต้องเผชิญโรคร้ายที่มีฤทธิ์รุนแรงพอ ๆ กับหัดซึ่งคร่าชีวิตชาวพื้นเมืองไปอย่างมหาศาล พวกเขาอาจไม่สามารถตั้งรกรากได้เลยด้วยซ้ำ
แต่เมื่อมองย้อนกลับไป สิ่งเหล่านี้กลับไม่เคยเกิดขึ้น และนั่นทำให้เรายิ่งมีแนวโน้มจะเชื่อใน “ชะตากรรม” บางอย่างของประวัติศาสตร์ อย่างไรก็ตาม หากมองในแง่กลไกของพลังที่ขับเคลื่อนอำนาจ การที่จุลชีพกลับมีบทบาทสนับสนุนการรวมศูนย์ของรัฐในยุคใหม่มากกว่าการขัดขวาง ก็เป็นสิ่งที่น่าพิจารณา ทหารและผู้ตั้งถิ่นฐานจากโลกตะวันตกไม่ได้มีเพียงเทคโนโลยีเป็นแต้มต่อ แต่ยังมี “ภูมิคุ้มกันที่สั่งสมจากประสบการณ์กับโรค” อีกด้วย โรคที่มาพร้อมกับนักสำรวจจากยุโรปจึงกลายเป็น “อาวุธลับ” ที่ทำลายชาวพื้นเมืองก่อนที่ผู้รุกรานจะลงจากเรือด้วยซ้ำ
แม้ว่าจะมีข้อสันนิษฐานว่าซิฟิลิสแพร่จากโลกใหม่กลับไปยังยุโรป แต่ผลกระทบของมันก็จำกัดอยู่ในระดับวัฒนธรรม โดยเฉพาะด้านศีลธรรมทางเพศ ไม่ได้ส่งผลกระทบในระดับการเมืองมหภาคอย่างที่โรคระบาดในยุคกลางเคยทำ เช่น กาฬโรคหรือโรคไข้ทรพิษ เพราะในยุคสมัยใหม่ ระบบอุตสาหกรรมและโครงสร้างทางการแพทย์มีความสามารถในการควบคุมภัยจากจุลชีพได้มากขึ้น ไม่ว่าจะผ่านระบบสุขาภิบาล วัคซีน หรือยาปฏิชีวนะ
อย่างไรก็ดี การปรากฏตัวของโรคเอดส์ และความกังวลเกี่ยวกับไวรัสกลายพันธุ์ในช่วงปลายศตวรรษที่ 20 ได้แสดงให้เห็นว่า จุลชีพอาจไม่ได้เป็น “ปัจจัยรอง” ที่ไร้ฤทธิ์เสมอไป และอาจหวนกลับมาเป็นปัจจัยหลักที่กำหนดแนวทางของอำนาจใหม่อีกครั้งได้ในอนาคต หากมีโรคระบาดใหญ่เกิดขึ้นซึ่งรุนแรงพอที่จะทำลายความสามารถของรัฐในการควบคุมระบบเศรษฐกิจและชีวิตสาธารณะ โครงสร้างของอำนาจอาจสั่นคลอนยิ่งกว่าผลกระทบจากภูมิอากาศหรือภูมิประเทศเสียอีก
ปัญหาคือเราไม่สามารถคาดการณ์จุดเริ่มต้นของเหตุการณ์เหล่านี้ได้อย่างแม่นยำ ไม่มีแบบจำลองใดที่สามารถควบคุมหรือคาดเดาธรรมชาติได้อย่างสมบูรณ์ แม้จะมีความพยายามทางวิทยาศาสตร์และการเฝ้าระวังระดับโลก การที่เรารอดพ้นจากโรคร้ายในอดีตไม่ได้แปลว่าจะรอดได้อีกในอนาคต ความคาดหวังว่าปัจจัยมหภาคในพันปีข้างหน้าจะยังคงเป็น “เทคโนโลยี” ไม่ใช่ “จุลชีพ” จึงเป็นเพียงสมมติฐานที่ตั้งอยู่บนความหวังมากกว่าหลักประกันใด ๆ
และแม้ว่าเทคโนโลยีจะมีบทบาทอย่างล้นเหลือในช่วงห้าศตวรรษที่ผ่านมา แต่บทเรียนจากการปฏิวัติการเกษตรในยุคโบราณก็ยังคงเตือนใจว่า ปัจจัยที่เปลี่ยนแปลงวิถีของอำนาจในระดับรากฐานที่สุดอาจไม่ได้ยิ่งใหญ่หรือก้าวหน้าเสมอไป บางครั้งสิ่งที่ทำให้โลกเปลี่ยนแปลงไปอย่างถาวร ไม่ใช่จักรกลที่ซับซ้อนหรืออาวุธล้ำยุค หากแต่เป็นสิ่งมีชีวิตขนาดเล็กที่เราแทบมองไม่เห็นด้วยตาเปล่า — และมันก็อาจย้อนกลับมามีบทบาทสำคัญอีกครั้งในศตวรรษของเรา.
อย่าลืมว่าหนังสือเล่มนี้เขียนขึ้นในปี 1997 — ยุคที่โลกยังไม่เคยรู้จักกับ COVID-19
บทถัดไปจะพูดถึงเรื่องการปฏิวัติครั้งแรกของ Sapiens การปฏิวัติเกษตรกรรม

2025-04-29 01:20:04PAN... แค่แพนเค้ก หรือ แผนล้อมโลกเรื่องอาหาร เมื่อหมากตัวจริงชื่อ Sebastian Joy
เราได้รู้จักกับคุณ Sebastian Joy กันไปแล้วนะครับ วันนี้เรามาขยายผลกันอีกหน่อย
ถ้าโลกนี้เป็นเกมหมากรุก อาหารคือกระดานที่ทุกตัวหมากต้องเหยียบเดิน และใครที่วางหมากอาหารได้...ก็วางโลกได้เหมือนกัน
ปี 2018 มีโครงการหนึ่งถือกำเนิดขึ้นในเยอรมนีอย่างเงียบๆ ชื่อว่า Physicians Association for Nutrition (PAN) เบื้องหน้าเหมือนเป็นมูลนิธิการกุศล ตั้งขึ้นมาเพื่อ "ช่วยให้หมอเข้าใจเรื่องโภชนาการจากพืช" แต่ถ้าเปิดแว่นขยายส่องให้ดีๆ มันคือหนึ่งในฟันเฟืองสำคัญของแผนเปลี่ยนอนาคตอาหารโลกจาก Animal-Based ไปเป็น Plant-Based ที่เป็น lab plant based ที่ไม่ใช่อาหารธรรมชาติแบบหลักแก่นที่ Vegan สืบทอดกันมา โดยอ้างเรื่อง "สุขภาพ" และ "สิ่งแวดล้อม" เป็นฉากหน้า
PAN นั้นเสมือนเป็นลูกสมุนตัวกลั่นของคนที่ชื่อ Sebastian Joy ชายหนุ่มสายโปรโมทแนว Vegan ที่ก่อนหน้านั้นก่อตั้งองค์กร ProVeg International ซึ่งมีสายสัมพันธ์กับพวก Start-up อาหารทางเลือก (ไม่ว่าจะเป็นเนื้อปลอม เนื้อพืชดีเอนเอ นมพืชที่มาจากจุลินทรีย์ ไปจนถึงการส่งเสริมวัตถุดิบจากแบคทีเรีย โรงงาน และห้องแลบ) แล้ว ProVeg ไม่ได้ทำงานเดี่ยวๆ นะจ๊ะ... เบื้องหลังเชื่อมโยงกับเครือข่ายที่หนุน World Economic Forum (WEF) และแนวคิด Great Reset ที่อยาก "รีเซ็ต" วิธีการกินของคนทั้งโลก โดยให้อาหารเป็น Plant-Based แบบ lab created และ Meat Lab-Based เป็นหลัก
ส่วน PAN ถูกใช้เป็น "หมากที่แต่งตัวเป็นหมอ" เพื่อเดินเกมไปสู่การแทรกแซงนโยบายประเทศต่างๆ ผ่านช่องทาง "สาธารณสุข" และ "การศึกษาแพทย์" เพื่อมาเป็นกำลังหลักให้ในแผนงาน
เรามาดูตัวอย่างผลงานเด่นของ PAN กันครับ 1. ผลักดันให้รวม Plant-Based เข้าไปในหลักสูตรแพทย์และพยาบาล (โดยใช้เหตุผลว่า "หมอต้องรู้จักอาหารเพื่อสุขภาพ") 2. ช่วยรณรงค์ให้โรงพยาบาล โรงเรียน และมหาวิทยาลัย เปลี่ยนเมนูอาหารเป็น Plant-Based 3. สนับสนุนงานวิจัย และโครงการ เช่น Green Food Experience ที่กดดันให้ภาคธุรกิจและภาครัฐบาลหันมาทำตาม "แนวทางอาหารยั่งยืน" แบบที่ PAN และพรรคพวกกำหนด 4. มีสถานะ "Observer" ในองค์การสหประชาชาติ (UN) เพื่อเสนอความคิดเห็นในการกำหนดนโยบายสาธารณสุขและสิ่งแวดล้อมระดับโลก
และเบื้องหลังอีกชั้นที่น่าสนใจ... Sebastian Joy มีความสัมพันธ์ลึกซึ้งกับวงการ Start-up อาหารใหม่ๆ ที่พยายามตีตลาด Plant-Based และ Lab-Grown Food อย่างเช่น Perfect Day, Beyond Meat, Mosa Meat ฯลฯ ผ่านการโปรโมท "โภชนาการจากพืชเพื่อสุขภาพที่ดีกว่า" โดยใช้ PAN เป็นเครื่องมือให้ดู "มีอำนาจทางวิชาการ" มากขึ้น
หรือถ้าให้พูดง่ายๆ คือ สร้างสนามแข่ง แล้วจับมือกับนักแข่งที่ตัวเองลงทุนไว้ PAN ดูเหมือนเป็นองค์กรกลางๆ ใสๆ แต่มันเชื่อมโยงกับโครงข่าย NGO และบริษัทเอกชนที่มุ่งแปลงร่างอาหารโลกอยู่เบื้องหลัง การที่ PAN ผลักดันนโยบายระดับประเทศ และแทรกซึมในระบบการศึกษา หมายความว่าอนาคตคนรุ่นใหม่จะถูกปลูกฝังแนวคิด "เนื้อสัตว์ไม่ดี" โดยไม่ทันรู้ตัว
แล้วมันเกี่ยวอะไรกับเรา? จินตนาการดูครับว่า - ถ้าวันหนึ่งโรงเรียนของลูกเรามีแต่เมนูถั่วเหลือง ซีเรียล นมโอ๊ต หรือ ไอศกรีมเวย์จากจุลินทรีย์ และห้ามเสิร์ฟเนื้อสัตว์ด้วยสารพัดเหตุผล เช่น เนื้อปนเปื้อนง่าย เนื้อทำให้เป็นมะเร็ง หรือแม้แต่สอนเด็กว่า เนื้อคือตัวการทำลายสิ่งแวดล้อมด้วย มีเทน นั่นอาจเป็นผลลัพธ์จากงานเบื้องหลังของ PAN - ถ้าวันหนึ่งนโยบายอาหารของประเทศเน้นลดเนื้อสัตว์ อ้างสุขภาพ อ้างสิ่งแวดล้อม อ้างโรคระบาด อ้างกฎแห่ง DNA ที่ถูกจดสิทธิบัตร แล้วโปรโมทเนื้อปลอมแทน นั่นอาจเป็นรอยเท้าของ Sebastian Joy ที่เดินมาก่อนแล้ว - ถ้าวันหนึ่งหมอจำนวนมากเชื่อว่า “เนื้อสัตว์คือตัวร้ายที่แพร่มะเร็งหรือทำให้สุขภาพเสีย” โดยไม่มีการตั้งคำถาม นั่นคือชัยชนะของหมากตัวนี้
ในขณะที่คนส่วนใหญ่คิดว่ากำลังเลือกอาหารเอง หรือ คิดว่าฉันกิน plant base / vegan เพราะรักโลก รักสุขภาพ แต่จริงๆ แล้วมีมือที่มองไม่เห็นกำหนด "ตัวเลือก" ไว้แล้วเรียบร้อย เพราะทั้งหมดมันไม่ได้เป็นอาหารธรรมชาติ มันคืออาหาร "สร้าง" ที่ไม่มีสัตว์, มันคืออาหาร "สร้าง" ที่ต้อง "สร้าง" มาจากโรงงาน แล้วเราต้อง "ซื้อ" มากินเท่านั้น ถ้าไม่สร้าง local ให้แข็งแรง อย่าหลงไปตามความสวยงามของการรักโลกในมุมเดียว เราอาจจะไม่สามารถปลูกพืชมาเป็นอาหารเองได้ เราอาจไม่สามารถเลี้ยงสัตว์เพื่อกินเองได้
PAN ไม่ใช่แค่องค์กรให้ความรู้ด้านโภชนาการ / PAN คือเครื่องมือในกระดานหมากรุกที่กำลังจัดการ "ตั้งโปรแกรมใหม่" ให้คนทั้งโลกกินตามแบบที่นายทุนและเครือข่ายเบื้องหลังเขียนบทไว้ และชายที่ชื่อ Sebastian Joy นี่แหละ...คือหนึ่งในผู้ถือหมากที่ยิ้มอยู่หลังม่าน
อาหารแห่งอนาคต มีทางเดินเหลือไว้ให้ เกษตรกร old school บ้างไหม สนธิสัญญาต่างๆเรื่องเมล็ดพันธุ์ เหลือทางเดินไว้ให้เกษตรกรบ้างไหม หรือสุดท้าย เราจะไม่มีไดเอทให้เลือก ให้ทะเลาะกัน เพราะสุดท้าย เราต่างต้องกินอาหารจากโรงงานเหมือนกันหมด บทความนี้คงจะเป็นได้แค่เพียง การตั้งคำถามขึ้นมาไว้ แต่ไม่มีคำตอบ ว่าเรากำลังโดนอ้าง plant based food มาเคลือบความเป็น อาหารโรงงาน (Plant Food) หรือเปล่าเพราะวันนี้หลายคนอาจมองว่าเป็นการตื่นตูม คิดมาก หรือแม้แต่ เราเลือกได้แหละ ก็ได้ครับ
ผมไม่ได้มีปัญหากับสายพืชล้วน ไม่ว่าจะเจ วีแกน แพลนท์เบส เพราะถ้ากินเป็น มองสารอาหารเป็น จัดการ anti nutrient ได้ดี มันก็ดีสำหรับคนนั้น แต่ซีรีส์นี้สำคัญที่ว่า plant based food is not PLANT food อาหารจากพืชไม่ใช่อาหารจากโรงงานครับ
ก่อนถึงวันที่เราจะไม่มีสิทธิ์แม้แต่จะเลือก #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

If you manage to get it up to date / uncorrupt the data, I give you full liberties to:
- The model itself
- Its XMF and/or XML skeleton
- Patching it to be compatible with any other gun mods
- other fixes
- and full credit handed over to you
I think this has honestly been abandoned by it's original developer, and since I am just hanging onto the file? I decided it'd be better maintained in someone elses hands, and with community much more responsible than Nexus. Honestly if I did not archive this mod? It would of been vaporware.
But in it's current state it's not fit for being playable. I did manage to save media of when it was playable however.

Os princípios básicos da criptografia.
Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.
Criptografia e descriptografia.
Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.
https://image.nostr.build/0e2fcb71ed86a6083e083abbb683f8c103f44a6c6db1aeb2df10ae51ec97ebe5.jpg
Figura 1-1. Criptografia e descriptografia
O que é criptografia?
Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.
Criptografia forte.
"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.
Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.
Como funciona a criptografia?
Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.
Criptografia convencional.
Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg
Figura 1-2. Criptografia convencional
Cifra de César.
Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.
Gerenciamento de chaves e criptografia convencional.
A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?
Criptografia de chave pública.
Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.
[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg
Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).
Como funciona o PGP.
O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.
Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.
Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para
problemas de distribuição de chaves e transmissão de dados. Usados em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.
Chaves.
Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.
Assinaturas digitais.
Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.
Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.
Figura 1-6. Assinaturas digitais simples
Funções hash.
O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.
Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.
Certificados digitais.
Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.
Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados para impedir tentativas de substituir a chave de uma pessoa por outra.
Um certificado digital consiste em três coisas:
● Uma chave pública.
● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.
O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável.
Figura 1-8. Anatomia de um certificado PGP
Distribuição de certificados.
Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).
Servidores de certificados.
Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.
Infraestruturas de Chave Pública.
Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).
Formatos de certificado.
Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.
O PGP reconhece dois formatos de certificado diferentes:
● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).
● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.)
Figura 1-9. Um certificado PGP
Formato de certificado X.509.
X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)
Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:
O número da versão X.509
— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.
A chave pública do titular do certificado
— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.
O número de série do certificado
— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.
O identificador exclusivo do detentor do certificado
— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)
O período de validade do certificado
— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.
O nome exclusivo do emissor do certificado
— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)
A assinatura digital do emitente
— a assinatura utilizando a chave privada da entidade que emitiu o certificado.
O identificador do algoritmo de assinatura
— identifica o algoritmo usado pela CA para assinar o certificado.
Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;
● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação
● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave
● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave
Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.
Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.
Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.
Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.
Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.
Verificando validade.
Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .
Estabelecendo confiança.
Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.
Introdutores meta e confiáveis.
Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.
Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.
Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.
Modelos de confiança.
Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:
Confiança Direta.
Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta.
Figura 1-11. Confiança direta
Confiança Hierárquica.
Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.
Figura 1-12. Confiança hierárquica
Teia de Confiança.
Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.
Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.
Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de
● se o usuário considera ou não uma chave específica válida
● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros
Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.
Níveis de confiança no PGP.
O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.
Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:
● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)
Para tornar as coisas confusas, também existem três níveis de validade:
● Válido ● Marginalmente válido ● Inválido
Para definir a chave de outra pessoa como um introdutor confiável, você
- Comece com uma chave válida, que seja.
- assinado por você ou
-
assinado por outro apresentador confiável e então
-
Defina o nível de confiança que você acha que o proprietário da chave tem direito.
Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.
Revogação de certificado.
Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.
Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)
Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.
Comunicar que um certificado foi revogado.
Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.
O que é uma senha?
A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.
Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?
PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.
Divisão de chave.
Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

2025-04-29 13:24:06Am 11. April 2022, einem sonnigen Frühlingstag, schaute ich gegen 11 Uhr seit langem wieder einmal bei Roßleben an der Unstrut mit Muße in den Himmel. Gemeinsam mit Regina, meiner Frau. Wir sind jetzt im Ruhestand – und hatten uns im Jahr 1974 unter dem Himmel von Roßleben verliebt.
Was wir da sahen, können Sie im Titelbild oben nachvollziehen. Überrascht beobachteten wir ein Weile, was da passiert, doch die Streifen, offenkundig von Flugzeugen hinterlassen, lösten sich nicht auf, sondern verbanden sich allmählich zu einem zusammenhängenden Dunstschleier, festgehalten im folgenden Foto:
Überrascht waren wir, weil wir vor knapp 50 Jahren am gleichen Himmel zwar auch schon Flugzeuge gesehen hatten, die hatten allerdings nicht derartige von Horizont zu Horizont reichenden Spuren hinterlassen. Einige Tage später gelang mir eine Aufnahme, die einen von anno dazumal vertrauten Kondensstreifen eines Flugzeuges zeigt:
Gemeint ist die senkrecht in der Bildmitte verlaufende kurze Spur. Darunter der waagrechte Streifen zeigt das heute eher übliche Bild.
Als neugieriger Mensch bat ich das für solche Fragen zuständige Bundesumweltamt um Auskunft, wie diese Himmelserscheinungen zu erklären sind. Hier die Fragen, die ich mit den Fotos an das Umweltbundesamt gesendet habe:
1. Seit wann genau hinterlassen Flugzeuge über deutschem Luftraum Spuren, welche länger als 5 Minuten am Himmel sichtbar sind, sich ausbreiten und in Form von Dunstschleiern über Stunden am Himmel verbleiben?
2. Inwieweit wurde die Durchführung entsprechender Beschlüsse, welche die beobachtbare Schleierbildung herbeiführen, von demokratischen Gremien unseres Landes, z.B. dem deutschen Bundestag, genehmigt?
3. Welche Entscheidungsträger in unserem Land sind für diese Vorgänge verantwortlich?
4. Gibt es in diesem Zusammenhang internationale Geoingeneering-Programme, an denen Deutschland beteiligt ist? Wenn ja, welche sind das?
5. Was ist Ihnen über Partikel bzw. Substanzen bekannt, welche die langandauernde Sichtbarkeit dieser Schleier verursachen?
6. Was ist Ihnen über Folgeschäden durch die offenkundige Beeinflussung der Lichteinstrahlung oder durch Herabsenken von Partikeln bzw. Substanzen in diesen Schleiern auf Pflanzen, Tiere und Menschen bekannt?
7. Welche Möglichkeiten sehen Sie in Ihrem Amt, zur wissenschaftlichen Aufklärung und ggf. Beendigung dieser Dunstschleier-Aktivitäten beizutragen?
Hier die Antwort des Bundesamtes:
Sehr geehrter Herr Professor, danke für Ihre Anfrage.
Aus unserer Sicht handelt es sich bei Ihren Beobachtungen um Kondensstreifen. Sie entstehen in hinreichend kalter Atmosphäre als Folge der Wasserdampfemissionen aus Flugzeugtriebwerken. Bei niedriger Feuchte lösen sich Kondensstreifen rasch wieder auf. Ist die Atmosphäre jedoch hinreichend feucht, können Kondensstreifen länger existieren und weiter wachsen. Unter geeigneten Bedingungen können sie sich zu großflächigen Zirruswolken, die im Falle einer solchen Entstehungsgeschichte Contrail-Cirrus heißen, entwickeln. Contrail-Cirrus ist dann nicht mehr von natürlichen Zirren unterscheidbar, falls nicht seine gesamte Entstehungsgeschichte beobachtet wurde.
Nehmen Zirruswolken, die optisch sehr dünn sein können, eine große Fläche ein, erscheint dem Beobachter der Himmel milchig weiß. Im Mittel sind rund 0,06 Prozent der Erde mit (linienförmigen) Kondensstreifen bedeckt. Gegenden mit hohem Flugverkehrsaufkommen erreichen deutlich höhere Bedeckungsgrade. So lag Mitte der neunziger Jahre der Wert für Europa bei 0,5 Prozent. Der Bedeckungsgrad durch Contrail-Cirrus ist noch nicht bekannt. Erste Schätzungen liefern Werte, die etwa zehnmal so groß sind wie der Bedeckungsgrad mit linienförmigen Kondensstreifen.
Altern Kondensstreifen, bleiben sie nicht glatt, sondern können Formen bilden. Dieser Vorgang ist ein lange bekanntes Phänomen und eine Folge der Turbulenz, die in der Atmosphäre allgegenwärtig ist. Diese Formen lassen sich auch durch Modellsimulationen reproduzieren.
Mehrere Kondensstreifen nebeneinander entstehen zum Beispiel dadurch, dass Flugzeuge festen Routen folgen und die Windrichtung in der Höhe von der Flugroute abweicht. Die Kondensstreifen verschieben sich dadurch seitlich. An Knotenpunkten der Flugrouten können sich Kondensstreifen unterschiedlicher Orientierung bilden. Als Folge der Verschiebung der Kondensstreifen können dann auch rautenförmige Muster entstehen. Da Windrichtung und -geschwindigkeit praktisch nie gleich sind, entstehen aus vormals geraden Mustern gekrümmte Formen. Außerdem fliegen Flugzeuge nicht immer nur geradeaus, sondern auch Kurven, insbesondere während Warteschleifen in Flughafennähe. In diesem Fall können gekrümmte Kondensstreifen entstehen.
Nähere Informationen zur Bildung von Kondensstreifen gibt das DLR auf folgender Internetseite: http://www.dlr.de/pa/desktopdefault.aspx/tabid-2554/3836_read-5746/
Uns sind die Vorschläge, die unter dem Stichwort Geo-Engineering oder Climate-Engineering zusammengefasst werden, bekannt. Wir haben dazu bereits 2011 eine umfassende Broschüre veröffentlicht.
In dieser Broschüre stellen wir auch die großen Risiken, die mit Geo-Engineering verbunden wären, ausführlich dar. Es gibt in Deutschland auch keinerlei Planungen staatlicher Institutionen zur Durchführung von Geo-Engineering. Die existierenden Vorschläge zum Geo-Engineering sind zum größten Teil nicht ausgereift und werden auch in der Praxis nicht angewendet. Es ist nicht geklärt, welche schwerwiegenden, unerwünschten Nebenwirkungen auftreten könnten. Zudem gibt es gar keine ausreichende rechtliche Basis für Geo-Engineering. Wörtlich heißt es in unserer Broschüre auf Seite 4: „Angesichts der Tragweite von Geo-Engineering-Maßnahmen und den großen Unsicherheiten bei der Abschätzung von Folgen im komplexen Erdsystem rät das UBA aus Vorsorgegründen zu größter Zurückhaltung und bis zu einer deutlichen Verbesserung des Wissens um die Interdependenzen zwischen Geoprozessen zu einem Moratorium für den Einsatz solcher Maßnahmen.“ (https://www.umweltbundesamt.de/publikationen/geo-engineering-wirksamer-klimaschutz-groessenwahn)

Da ich kein Wolken-Forscher werden mag, überlasse ich Ihnen gern das Urteil über meine Fragen und die Passung der Antworten seitens unserer Regierungsbehörde.
Spannend ist heute, drei Jahre nach diesem kleinen Briefwechsel (erstmals veröffentlicht im April 2022 auf der Plattform der Zukunftskommunen), dass vom Senat des US Bundesstaates Florida am 3. April 2025 ein Gesetz verabschiedet wurde, welches das Versprühen von Chemikalien durch Flugzeuge unter Strafe stellt. Hier ein kurzer Auszug:
Verbot von Geoengineering und wetterverändernden Aktivitäten
(1) Die Injektion, Freisetzung oder Dispersion von Chemikalien, chemischen Verbindungen, Substanzen in die Atmosphäre innerhalb der Grenzen dieses Staates zu dem Zweck der Beeinflussung von Temperatur, Wetter, Klima oder um die Intensität des Sonnenlichts zu beeinflussen, ist verboten.
(2) Jede Person, jede öffentliche oder private Körperschaft, die eine Geo-Engineering-Aktion oder Wetterbeeinflussung unter Verstoß gegen dieses Verbot durchführt, macht sich schuldig eines Verbrechens dritten und zweiten Grades, auf das eine Geldstrafe von bis zu 100.000 Dollar fällig wird. ... Luftfahrzeugbetreiber oder Fluglotsen, die ein Verbrechen dritten Grades dieser Art begehen, werden bestraft mit einer Geldstrafe von bis zu $5.000 und bis zu 5 Jahren Gefängnis.
Den kompletten Text können Sie hier nachlesen. In Tennessee sowie in über 20 weiteren US Bundesstaaten sind ähnliche Gesetze auf dem Weg. Jetzt dürfen wir neugierig sein, wie die Rotkäppchen - Story in anderen Ländern, z.B. in Deutschland weitergeht.

2025-04-29 06:48:44Haben Sie schon einmal einen Intelligenztest gemacht? Da geht es darum, in beschränkter Zeit eine Vielfalt rationaler Denkprozesse so präzise wie möglich korrekt zu absolvieren, wenn man gern einen hohen Intelligenzquotienten bescheinigt haben mag. Unsere gesamte Schulbildung ist überwiegend auf die Entfaltung dieser Art kognitiver Potentiale ausgerichtet. Allerdings ist es weniger eigenständiges Denken, das im Fokus steht. Meist handelt es sich um "betreutes" Denken in vorgegebenen begrifflichen Kategorien und mit vorgegebenen Frage-Antwort Schemata, welche vorab zu pauken sind, wenn man bestehen möchte.
Und wie steht es um das Mitfühlen mit anderen Geschöpfen - mit Grashüpfern, Ameisen, Pflanzen, Fischen, Schweinen oder Rindern? Und wie ist es um das Mitfühlen mit Menschen bestellt, welche infolge von Kriegshandlungen schwerste körperliche und seelische Schäden davontragen oder sterben? Wurden solche Fragen in Ihrer Ausbildung thematisiert? Meine Erinnerung bringt das Sezieren von Fröschen und Fischen im Biologieunterricht hervor, wobei Fragen an die Lehrer nach dem Leiden der Tiere als unpassend abgetan wurden. Die Überlebenden unserer Vorfahren in den Weltkriegen nach den erlittenen Leiden zu fragen: Hat Sie dazu einer Ihrer Lehrer oder Professoren ermutigt?
Sollten Sie bis hierher mitschwingen und ähnlich empfinden, dass unser Potential zum Mitfühlen in unserer Gesellschaft gegenüber kognitiven Potentialen wenig kultiviert und gepflegt wird, dann könnte sich ein Pfad auftun, unsere entstehende Regionalgesellschaft zu stärken.
Wenn wir unsere Sinneskanäle öffnen für das Befinden der Schöpfung, in der wir uns gerade bewegen, erschließen sich große Energiequellen. Diese können uns dienen, aus der vom hypertrophierten Denken entstellten Welt zurück in unsere Mitte zu finden. Zum einen können wir wahrnehmen, wie das Leben in und um uns pulsiert, können mitfühlen in dem zauberhaften Geschehen, das wir in besonderer Weise im gerade erwachenden Frühjahr erleben dürfen. Zum anderen werden wir Geschöpfe in Not oder Bedrängnis wahrnehmen und können so erfahren, dass es auch uns selbst wohl tut, wenn wir uns für diese engagieren. Wer schon einmal ein Tier geheilt hat oder sich für Opfer von Gewalthandlungen eingesetzt hat, kennt das.
Diese unmittelbaren Energiequellen geben uns Kraft, Bestätigung und Befriedigung - und diese Energie kann jeder Mensch zu jeder Zeit seines Lebens anzapfen.
Voraussetzung ist lediglich, dass wir die gewohnten "betreuten" Denkprozesse, auf die wir programmiert wurden, lernen zu unterbrechen. Dass wir die begriffliche Diarrhoe und Bedeutungsverdrehung seitens gefühlsarmer oder gefühlloser Menschen und ihrer Lakaien, welche uns aktuell zu Kriegshandlungen animieren wollen, hinter uns lassen. Dass wir uns nicht wie in den 1930er Jahren mit Worten wie "Kriegstüchtigkeit" gegen andere Völker aufhetzen lassen. Wenn wir solchen verbalen Entgleisungen nicht länger Aufmerksamkeit schenken, schaffen wir Zeit und Raum für das Mitfühlen.
Das Mitfühlen gibt uns ethische Orientierung, zeigt Wege auf, unsere Bestimmung zu finden und gibt uns die Kraft, unser Leben nach unseren Wertvorstellungen zu gestalten. Es beantwortet uns Fragen nach dem WOHIN und WOZU.
Das selbst Denken ist ein Werkzeug, welches uns, nachdem wir in unsere Mitte gefunden haben, dazu dienen kann, die Frage nach dem WIE zu klären.
Mit gleichgesinnten mitfühlenden und selbst denkenden Menschen ist es möglich, an unserer Regionalgesellschaft zu werkeln und funktionierende, auf Vertrauen basierende Initiativen und Gemeinschaften zum Blühen zu bringen. In meinen Blogbeiträgen sind seit 2018 einige davon beschrieben. Und ein psychologischer Zusammenhang scheint bemerkenswert: In solchen Gemeinschaften fühlen sich auch die Beteiligten wohl. Dazu liegen wissenschaftliche Studien vor, welche Sie in meinem Publikationsverzeichnis finden.
