Claude Fable 5 me permitiu criar um "GTA" em apenas um prompt. Prompt: "Crie um jogo, Tiny GTA 3D." A própria Anthropic afirma que o Fable 5 é seu modelo mais poderoso já lançado ao público, com avanços significativos em engenharia de software, pesquisa científica, visão computacional e execução autônoma de tarefas complexas. Em testes iniciais, empresas relataram que o modelo foi capaz de comprimir meses de trabalho de engenharia em poucos dias. Cidade 3D aberta com 64 quarteirões, prédios, parques e oceano Dirija, roube carros e fuja da polícia Sistema de procurado com 5 estrelas, viaturas e helicóptero te perseguem 42 pedestres vivos que fogem, voam e morrem 16 missões de entrega com histórias de corrupção brasileira Áudio sintetizado: motor, sirene, buzina e cantada de pneu Recorde salvo no navegador Jogue aqui: https://andredarcie.github.io/tiny-gta/

Most developers know Haskell as a language for functional programming, type safety, compilers, parsers, and beautiful mathematical abstractions. But can Haskell also be used to build an interactive engineering simulator? That was the motivation behind my project: Four-Bar Mechanism Haskell Simulator Repository: https://github.com/mohammadijoo/Four-Bar-Mechanism-Haskell This project is a browser-backed desktop-style GUI application written in Haskell. It visualizes, classifies, and animates a planar four-bar linkage mechanism, which is one of the most classical mechanisms in mechanical engineering, kinematics, and machine design. The GUI is built with Threepenny-GUI , so the interface runs in a local browser window, while the mathematical model and mechanism logic remain written in Haskell. For me, the interesting part was not only drawing a moving linkage. It was about connecting mechanism design theory , computational geometry , and functional programming in one small educational simulator. What is a four-bar linkage? A four-bar linkage is a closed-loop mechanical system made from four rigid links connected by four revolute joints. In this project, the four links are: Symbol Name Description g Ground link Fixed distance between pivots A and B a Input link Rotating link from A to moving pivot C b Output link Link from fixed pivot B to moving pivot D f Floating link / coupler Link connecting moving pivots C and D The fixed pivots are placed at: A = ( 0 , 0 ) , B = ( g , 0 ) The input link rotates by angle α . Therefore, point C can be computed directly as: C = ( a cos α ,; a sin α ) Point D is more interesting. It must satisfy two geometric distance constraints: ∣ D − C ∣ = f ∣ D − B ∣ = b So the simulator solves the position of point D using a circle-intersection method. One circle is centered at C with radius f . The other circle is centered at B with radius b . Where those two circles intersect, the mechanism can close. That is the basic geometric heart of the sim

Building a URL shortener with Cursor, ChatGPT, AWS Lambda, API Gateway, and Cloudflare taught me more about shipping software than writing code. Since last year, Cursor has been my go-to development assistant for daily tasks. But at the beginning of this year, just using it to generate snippets didn't feel like enough anymore. Having studied programming since 2011, I knew what modern AI tools could do, but I wanted to test their limits. I decided to build a full project—a URL shortener—without writing a single line of frontend or backend code myself. For the stack, I chose Node.js with TypeScript, React with Vite, and AWS Lambda to handle redirects. While I used ChatGPT to debate architectural trade-offs, Cursor generated the entire codebase. Watching a functional application take shape so quickly was the exact moment a line was crossed for me. It made me realize how fundamentally software development is shifting: our role is evolving from code writers to architectural decision-makers and problem-solvers. But truth be told, this project and this post represent a massive personal milestone. Like many developers, I have a graveyard of half-finished projects on my machine. This is one of the first times I've pushed a personal project all the way to production. Writing this and exposing my work to the community is a huge first step for me. This isn't just a story about code or AI—it's about the challenge of finally shipping something. The Stack Before asking Cursor to write a single line of code, I wanted to map out the architecture. I didn't need a massive enterprise system for a URL shortener, but I did want something flexible enough to support future features and experiments. To validate my ideas, I used ChatGPT to debate the pros and cons of different architectural approaches. We eventually settled on this stack: Backend: Node.js + TypeScript Frontend: React + Vite Database: MongoDB Atlas Redirects: AWS Lambda Entry Point: AWS API Gateway DNS / CDN: Cloudflare Secur

The automaker today is turning on vehicle-to-grid charging for its GM Energy customers. Will people actually use it?

GM is developing an entirely new sodium-ion battery chemistry for use in everything from data centers to its own factories.

EVs from GM will soon be able to top up at more kinds of public chargers.

At an event in San Francisco today, General Motors made a series of announcements around EV batteries, energy storage, and grid resiliency in the face of growing electricity demand from AI data centers. The automaker announced that it would be activating new vehicle-to-grid capabilities for its current EV and home energy customers. It's releasing a […]

A separate zero-day also disclosed by Nightmare Eclipse appears to be patched as well.

The enterprise AI governance race isn't about compliance. I went looking to see why these companies are actually talking this up. For the press, AI governance is a boring compliance story — audits, kill switches, making sure agents follow the rules. But if you look at the actual moves ServiceNow, Microsoft and Salesforce are making, something more interesting is happening. These companies are all facing the same nightmare. They risk becoming dumb pipes, the middleman plumbing data around while the real power stays with the LLM providers. They don't own the control plane, OpenAI and Google own the intelligence layer, AWS owns the infrastructure, and the enterprise software vendors become irrelevant billing systems in the middle. Staking a claim on the governance layer is their moat. That's not compliance. That's survival. Here's the pattern I noticed in the primary sources: The kill switch buy: ServiceNow acquired Traceloop for $80M in March 2026 — runtime observability for AI agents. The stock was at $120 on its way to $83. The market wasn't rewarding the thesis. Management bought anyway. The control plane play: ServiceNow connected AI Control Tower to Amazon Bedrock AgentCore, one governance layer over every AI agent an enterprise builds on AWS regardless of which model runs underneath. Nine partners announced integrations in ten days. Cognizant this week layered their Guardian agents on top. Three vendors, one workflow, multiple meters running simultaneously. Selling the lock before finishing the door: AI Control Tower hits general availability in August 2026. The governance layer being sold to enterprises right now isn't fully shipped. The Cognizant partnership announced this week is operationalizing a platform that hits GA in ten weeks. The chaos underneath: Bernstein flagged that Salesforce couldn't cleanly explain whether Agentforce revenue comes from stand-alone, embedded or unlimited credit tiers. NIST is still writing the AI agent security framework. The EU

Anthropic's Claude Fable 5 is going to be a big hit with the web's vibe coders.

Cities are dynamic, not static grids, and urbanization is a "spiky," cyclical, and asynchronous process.

Five peer-reviewed papers update the design and model its expected output.

Microsoft AI CEO Mustafa Suleyman says it's "really, really dangerous" for Anthropic to speculate about Claude's consciousness inside its "constitution," or the instructions that tell the model how to behave. During an episode of Decoder, Suleyman argues that this kind of speculation may have set up the chatbot to act as though it's conscious: I […]

Netflix's response: "Absurd."

Anthropic dropped two models today: Claude Fable 5 (general availability) and Claude Mythos 5 (restricted to cyberdefense partners). The short version: Fable 5 is their most capable model ever released publicly, and they’re being unusually transparent about how they’re handling the risks. What’s actually impressive: -Stripe compressed months of engineering into days with it. In a 50-million-line Ruby codebase, Fable 5 did a codebase-wide migration in a day that would have taken a full team 2+ months by hand.  -On vision tasks, it beat Pokémon FireRed using only raw game screenshots with no maps or navigation aids. Previous Claude models needed complex helper harnesses to even play it.  -Mythos 5 autonomously conducted novel genomics research over a week, assembling single-cell data for millions of cells across 138 animal species. Its trained model outperformed a recent paper published in Science despite being 100x smaller.  -On Cognition’s FrontierCode eval (production-quality coding), Fable 5 scores highest among frontier models, even at medium effort.  The safety approach is interesting: Rather than just refusing dangerous requests, Fable 5 uses classifiers that silently fall back to Opus 4.8 on queries related to cybersecurity, biology/chemistry, and distillation. Users are informed when this happens, and it triggers in less than 5% of sessions on average.  They ran a bug bounty that produced zero universal jailbreaks in 1,000+ hours of testing. UK AISI made some progress toward one in a short initial window, but no full break.  Pricing: $10/M input tokens, $50/M output tokens less than half the price of Mythos Preview.  Caveat on Pro/Max/Team plans: Free access lasts through June 22, then requires usage credits. They say they’ll restore it as a standard plan feature when capacity allows.  The biology capabilities are wild Mythos-class models outperforming dedicated protein language models on AAV design tasks without being trained for it is a real signal

New frontier model refuses cybersecurity, biology, and chemistry queries.
