A Evolução da Esquerda e da Direita: Um Contexto Histórico e Ideológico

Os termos “esquerda” e “direita” surgiram na Revolução Francesa (1789–1799) para distinguir quem se sentava ao lado do presidente da Assembleia: as forças favoráveis às reformas radicais (à esquerda) e as defensoras da monarquia e da ordem estabelecida (à direita). Com o século XIX e o advento do liberalismo económico, a direita passou a associar-se ao livre mercado e ao direito de propriedade, enquanto a esquerda defendeu maior intervenção estatal para promover igualdade.

No final do século XIX e início do século XX, surgiram o socialismo e o comunismo como correntes mais radicais da esquerda, propondo a abolição da propriedade privada dos meios de produção (comunismo) ou sistemas mistos com forte regulação e redistribuição (socialismo). A resposta liberal-conservadora evoluiu para o capitalismo democrático, que combina mercado livre com alguns mecanismos de assistência social.

Hoje, o espectro político vai além do simples eixo esquerda–direita, incluindo dimensões como:

• Autoritarismo vs. Liberdade: grau de controlo do Estado sobre a vida individual e as instituições;
• Intervenção Estatal vs. Livre Mercado: equilíbrio entre regulação económica e iniciativas privadas;
• Igualdade Social vs. Mérito e Responsabilidade Individual: ênfase na redistribuição de recursos ou na criação de incentivos pessoais.

Este modelo multidimensional ajuda a capturar melhor as posições dos partidos contemporâneos e as suas promessas de governação.

Simple design

For as long as I remember, I’ve believed in simple design as a principle in my practice. It feels fundamental to me when I think about good design.

At the same time, I see many successful examples of complex products in the world. So I decided to ask, what value is simple design really providing me and my work?

Is it nostalgia?

I sometimes wonder if simple design is rooted in nostalgia. An example I like to use is:

Imagine yourself in the year 1981. You just purchased a brand new desk calculator. You are excited because you should be able to do any type of paperwork calculations you can imagine on it.

As you start to use it for the first time, it immediately prompts you to update its software. After using it for a few calculations, it asks you to fill out a survey about your experience. One day in the middle of adding up your checkbook, it interrupts you to tell you about a new leather-bound desk calendar the company just released. Sometimes in the middle of a complex calculation, the calculator will lag and crash. You have to restart it often to fix the issue.

I have a feeling that a person in 1981 would think this is a terrible calculator. They purchased the device to perform their calculations, nothing more. Why is it requiring so much more of their attention and effort?

Focus

I think simple design often refers to a focused product. A product that does a specific task can sometimes do that task really well. Products that try to do many things can offer a lot of value, but rarely do all the things well.

Some people prefer to use specific tools for specific tasks. Others prefer a wide variety of features.

I think the benefits of using fewer products are often a major reason complex products are successful. They may not be focused, they might be lower quality as a result, but people can use them for a wide variety of applications.

You can open a can of beans with a Swiss Army Knife — it will get the job done.

Art and subjectivity

Maybe simple design is valuable for intangible reasons. There is an art to simplicity. There is a beauty to simplicity.

A user can see more of the product's intentionality. The creator chose to leave certain features out. They decided what to include. The product likely exudes more vision and personality.

That might be unnoticed by some, but very valuable to others who care about craft. People who value the experience as much as the result.

Ease of use

I think a true benefit of simple design is the effect it has on ease of use. The less things there are to do in a product, the more obvious the things you can do become.

A simple product requires less of a user. That means a user can stay focused on their own needs and use the product in ways they define. They will encounter boundaries which limit them. These limitations could drive some away, but some might be engaged to find new and creative ways of working.

When to abandon simple design

I think the sad news is simple design is ultimately a limiting factor of a product's growth. I think there are many examples of this throughout the course of history (i.e. Ello vs Facebook, Rdio vs Spotify, Simplenote vs Notion, VSCO vs Instagram, Clear vs Things, Peach vs Twitter, etc). At the same time, I think 'simple design' does provide an entry point to successfully define what a product is.

The biggest challenge is continuing to evoke the benefits of simple design in an established product, while allowing a product to evolve and grow to meet its users' needs. That is a balancing act that very few products have ever achieved, but feels like an ideal that successful products should strive for.

One of Charlie Deets Writings

After being featured in the NY Times and WSJ, New York City officially opens a major addition to Central Park, the Davis Center at the Harlem Meer. Designed by architect Susan T Rodriguez in collaboration with Mitchell Giurgola, the renovation project replaces the old Lasker Rink and pool with a recreational facility that’s built directly into the landscape, restoring nature, reconnecting paths, and creating a year-round space for community activity. At the heart of the new design is a transformative water feature that shifts with the seasons, from a skating rink in winter to a lush green lawn in spring and fall and a pool in the summer.

The center’s new oval-shaped pool sits lower than the old one, surrounded by a gently sloped grassy berm. In winter, the pool becomes an ice-skating rink, making the site a destination in every season. A splash pad at the end of the water feature offers extra water play in the summer. By integrating the design into the natural shape of the land, the architects were able to open up the space around the pool and allow the landscape to flow around it, resulting in a setting that feels like it’s always been there.

Sustainability was a core part of the project. The building is expected to earn LEED Gold certification, thanks to features like passive ventilation, locally sourced stone and wood, energy-efficient systems, and a roof that absorbs rainwater. Bird-safe glass helps protect local wildlife, and recycled materials from the old building were reused during construction. Even more important, the new center supports free and low-cost programming year-round, including education, nature walks, community events, and recreation. It’s designed to welcome all kinds of visitors—from families and school groups to joggers, birdwatchers, and casual parkgoers.

Large Language Models (LLMs) have transformed software engineering, but their application to physical engineering domains remains underexplored. This paper evaluates LLMs' capabilities in high-powered rocketry design through RocketBench, a benchmark connecting LLMs to high-fidelity rocket simulations. We test models on two increasingly complex design tasks: target altitude optimization and precision landing challenges. Our findings reveal that while state-of-the-art LLMs demonstrate strong baseline engineering knowledge, they struggle to iterate on their designs when given simulation results and ultimately plateau below human performance levels. However, when enhanced with reinforcement learning (RL), we show that a 7B parameter model outperforms both SoTA foundation models and human experts. This research demonstrates that RL-trained LLMs can serve as effective tools for complex engineering optimization, potentially transforming engineering domains beyond software development.

Collapse.

It's a slow burn.

The LA Fires started decades ago.

Hemingway said, when asked how he went broke:

"Slowly, then all at once."

That’s how collapse happens. Slowly, then suddenly.

Campfire

Ever build one?

You gather wood. Stack the foundation. Set the fuel. Light it up.

If it catches, keep going. Got to stoke it. Feed it. Watch it. In time, the fire's good.

Process It takes time.

Time to gather, build and ignite.

People come at the end. When the flame's dancing.

Like Sunday dinner.

People gather when food's ready. But, only the cook was in the kitchen.

Slow

Societal collapse's similar.

It takes years.

Decades.

Centuries.

A slow cook.

When people notice, the meal’s made. By the time they smell the fire, the forest’s already burning.

People see collapse, but it fell long time ago.

LA

Water, ran dry. Power went out. Fuel stations, empty. Help wasn't on the way.

Politicians politicking.

Making feel-good promises. People believed them. All bad decisions. One after another. They voted for it.

In time, it adds up.

Then, it falls down.

Shift

Analog to digital I work in animation.

Started analog, paper and pencil. It went digital. Scanners, tablets and all.

Veterans, didn't see it coming. Die-hards, refused to acknowledge. They went out of work. Those who adapted—they run the shows now.

Lockdowns

2008, I started a studio.

100% remote. A virtual company.

Some laughed. Others got angry. Said it wouldn't work. They couldn't see.

2020 comes with lockdowns.

Everyone scrambles. Those already digital, thrived.

The rest, shutdown.

History

The Wheel We carried goods. Then came the wheel.

Movement exploded. Trade thrived. Cities rose.

Hunter-gatherers? Left behind.

Collapse wasn't sudden. It was quiet. A shift.

The new formed. The old faded.

Change was inevitable.

Gunpowder

War changed.

Castles crumbled. Swords became relics. Power shifted.

Empires that adapted, thrived. Those that didn't, vanished.

Adapt or die.

The Internet

Borders blurred. Knowledge spread. Walls fell.

Old industries resisted. New empires emerged.

Collapse? No. A new frontier.

Borderless commerce. Shrinking government.

Info and influence, moving fast.

Bitcoin

Money, redefined.

No banks. No middlemen. Just code.

Governments dismiss it. Institutions fear it. But change ignores permission.

A ledger, transparent. A system, unstoppable. Like the internet rewrote communication, Bitcoin rewrites money.

Each invention displaced the old world.

Each collapse brought new opportunity.

Repeats

Mayans Built pyramids. Charted the stars. Cities thrived.

Then, slow decline.

Deforestation. Drought. Conflict.

People scattered.

Cities abandoned.

By the time the Spanish arrived, the fall was old news.

Romans

Not a fall. A fade.

Corruption. Inflation. Invasions. Cracks formed.

The West crumbled. The East endured.

Rome never vanished. Its laws, language, culture? Still here.

Japan

Collapse? No. Reinvention.

Shoguns fell. Meiji rose. Feudal to industrial. War crushed it. Post-war rebuilt it.

The '90s?

A peak. Tech giant. Economic force.

Then, stagnation. Aging population. Debt. Decline.

Still here. Still strong. But no longer rising.

Rhyme

US

Once a colony. Then an empire.

England ruled. America rose. Industry boomed. The 20th century belonged to the U.S.

A superpower. Factories roared. Gold backed the dollar.

A nation built on sound money.

Then, fiat. Paper promises. The gold standard abandoned.

Inflation crept in. Prices rose. Debt piled up. Each decade, the dollar bought less. Wages stagnated. Savings eroded.

Easy money, easy people.

Debt fueled bubbles. Each crash, deeper. The system, fragile.

Wealth concentrated. Time and energy, lost meaning.

A quiet nihilism grew.

People worked more. Gained less. Purpose eroded. Culture followed.

A nation distracted, chasing illusions of prosperity.

Today

The debt's bigger. The politics, fractured. The system strains. The foundation shifts.

The old fades into new.

What's next?

Every collapse starts slow. Then, all at once.

Change

Collapse is change.

It's natural. We see it throughout history.

Like a campfire—fire consumes, but it also brings warmth. Like dinner—before the meal, there’s preparation, transformation. Like LA fires—destructive, painful, but from the ashes, renewal. Possibly.

"To decompose is to be recomposed. That's what nature does. Nature, through whom all things happen as they should, and have happened forever in just the same way, and will continue one way or another endlessly."—Marcus Aurelius

Collapse isn’t the end.

It’s transition.

Preparing

"The Romans were reluctant to acknowledge change, and so are we." —The Sovereign Individual

Florida has hurricanes.

Happens every year. The news reports. Satellites confirm paths. Some, listen and prepare. Others, don't.

The storm comes.

Those prepared, benefit. The rest, suffer.

Like the old animators. They resisted. Now, they’re gone.

Collapse has warnings. How to prepare:

Mindset

Stay calm. See the patterns. Change is constant. Opportunity hides in disruption. Zoom out. Fear distorts judgment.

Skill Development

Learn adaptability. Master digital tools. Understand money. Grow networks. Invest in knowledge, not just assets.

Philosophy

Think long-term. Collapse spans generations. Pass down wisdom. Build resilience. Grow beyond survival—thrive.

Action

Own less, know more. Create. Don’t just consume.

Be part of what’s next.

Conclusion

The fire’s already burning. You can tend it—or watch it burn everything down.

There's a saying:

"There are three types of people in this world: those who make things happen, those who watch things happen, and those who wonder what happened."—Pat Riley

Be the former.

We are excited to announce the finalization of our DVMCP specification update, which integrates the latest Model Context Protocol (MCP) version 2025-03-26 and other improvements. This article highlights the key points of this update, and the differences between our initial vision and the final specification, providing insights into how our ideas evolved during the drafting process.

The Journey from Concept to Specification

Last week, we shared our vision for updating the DVMCP specification to better integrate with the Model Context Protocol. After extensive drafting and feedback, we've finalized a specification that maintains our core vision while making important refinements to ensure optimal functionality, interoperability, and user experience. We are also improving the tagging of our specifications to make it more consistent, using the draft mcp:2025-03-26 rev1 tag to identify the version of the specification and the revision number we are in. We hope this will make the specification clearer and easier to track changes.

Key Changes in the Final Specification

Refined Event Kind Structure

In our initial proposal, we outlined a modular event structure with dedicated event kinds for server announcements (31316) and separate kinds for capability categories (31317, 31318, and 31319). The final specification maintains this approach but provides more detailed implementation guidelines.

Enhanced Ephemeral Events

One of the most significant refinements involves our approach to ephemeral events. The final specification clearly defines three ephemeral event kinds:

• Requests (25910): Client requests to servers
• Responses (26910): Server responses to client requests
• Notifications (21316): Status updates, progress information, and interactive elements

This approach provides a more efficient communication pattern while reducing unnecessary storage burden on relays.

Standardized Content Structure

While our initial vision mentioned separating Nostr metadata and MCP payloads, the final specification provides concrete implementation details:

• Content Field: Contains stringified MCP JSON-RPC messages, maintaining full compatibility with the MCP specification
• Tags Field: Contains all Nostr-specific metadata using standardized tag patterns

This clear separation ensures that both protocols can operate seamlessly together without compromising either protocol's integrity.

Comprehensive Protocol Flows

The final specification includes detailed protocol flows for:

1. Public Server Discovery: Finding servers through published announcements
2. Private Server Discovery: Direct connection to servers using the MCP initialization process
3. Capability Operations: Standardized patterns for listing, executing, and managing all capability types

These flows provide implementers with clear guidance on how to build compliant clients and servers.

Payment and Authorization

The specification now includes concrete implementations for payment handling and authorization:

• Payment Required Notifications: Using the ephemeral notification kind (21316) with specific tag patterns
• Authorization Flow: Leveraging Nostr's cryptographic properties for secure authorization

What Remained Consistent

Despite these refinements, our core vision remained intact:

1. Expanded Capability Support: The specification fully embraces MCP's complete capabilities framework, including tools, resources, and prompts
2. Modular Architecture: The separation of server announcements and capability listings improves maintainability and extensibility
3. Protocol Interoperability: The specification maintains compatibility with both Nostr and MCP

Implementation Status

With the specification now finalized, we're updating our reference implementations:

• DVMCP-bridge: Server-side implementation for exposing MCP capabilities through Nostr
• DVMCP-discovery: Client-side library for discovering and consuming MCP capabilities via Nostr

Community Involvement

We want to express our gratitude to everyone who provided feedback on our draft specification. Your insights helped shape a more robust and practical protocol.

Looking Forward

This specification represents a significant advancement in bridging the Nostr and MCP ecosystems. By providing a standardized way to discover, access, and utilize MCP capabilities through the Nostr network, we're enabling new possibilities for applications.

We invite developers to explore the final specification and begin building with our reference implementations. Together, we can create a more open, interoperable, and powerful ecosystem

The complete specification is available at 2025-03-26.md.
