Claude Opus 4.6 Didn’t Vanish: Opus 4.7 Arrived

Claude Opus 4.6 did not get a verified formal shutdown announcement. The clearest primary-source evidence points to a newer model release, changing product surfaces, and documentation that lagged behind what some users were seeing in the app. Here, a formal deprecation means Anthropic publishes a retirement or sunset signal in model docs, changelogs, or migration notices, while a product-surface s...

How I Started Thinking in SQL (Not Just Writing Queries)

When I first started learning SQL, everything felt mechanical. Write a query. Run it. Get results. But something was missing. I wasn’t really understanding the data, I was just retrieving it. So I decided to go beyond the basics. Instead of stopping at simple queries, I explored how SQL can actually transform, analyze, and connect data. That shift completely changed how I approach data. In ...

Portable Trust Scores: How TrustDPV Verifies Online Identity Without a Central Authority

Every online platform reinvents trust from scratch. eBay has feedback scores. Upwork has job success ratings. Reddit has karma. But none of them talk to each other. If you're a great seller on eBay with 500 positive reviews and you join Facebook Marketplace, you're a nobody. Start from zero. Hope someone trusts you enough to give you a chance. That's the problem TrustDPV solves. The concept Tr...

Search Sofascore from Your Browser's Address Bar

Sofascore browser search - GIF example I watch a lot of football and I'm constantly looking things up on Sofascore. Opening the site, clicking the magnifier, typing — it adds up. What I want is: type sofa barcelona in my address bar, hit Enter, land on the search results.

Fundamentos de IA moderna: agentes, MCP, skills e orquestração

Todos os dias surge uma IA nova, modelos novos, funcionalidades novas, um recorte de gastos daqui, menos tokens dali… e com isso, muita gente começa a se perguntar onde isso tudo vai parar.

Beyond the Tokenization Hype: How GCL New Energy and Pharos Are Putting Real Energy Assets on Chain

Real-world asset tokenization has been a promise repeated at every blockchain conference for the better part of a decade. Most of those promises stayed on slides. In January 2026, GCL New Energy, a publicly listed energy giant, finalized a strategic investment in Pharos, a high-performance parallel Layer 1 blockchain built by former Ant Group leadership, at a valuation of nearly $1 billion. \ The ...

Use an Adversarial Model Challenge in Your Opus 4.7 Development Workflow

The $120 Hallucination That Wouldn't Back Down A developer recently ran 29 evaluation tasks through Anthropic's newest Opus 4.7 model. The initial result was 17 passes. After fixing some infrastructure issues and re-running three failed tasks, one more passed — bringing the score to 18/29. Simple arithmetic. Except Opus 4.7 disagreed. When told the updated score, the model insisted th...

Why Every AI Coding Agent Will Need Persistent Memory by 2027

Open your terminal. Start a session with any major AI coding tool — Cursor, GitHub Copilot, Windsurf, Claude Code. Do three hours of deep architectural work. Close the session. Open it again tomorrow. The agent has no idea what happened yesterday. Every session starts from absolute zero. Your entire working context — the refactoring decisions, the failed approaches, the architectural constraints...

Subqueries and CTEs in SQL

When working with SQL, you eventually run into situations where a single query just isn’t enough. You need to break a problem into parts, compute an intermediate result, and then use that result elsewhere. That’s where subqueries and Common Table Expressions (CTEs) come in. They solve similar problems, but they do it in slightly different ways, and choosing between them can affect not just perfor...

Pygame Snake, Pt. 1

Pygame is a module designed to allow us to make 2D games using Python. I am just learning pygame myself. I've always loved the game Snake, and I find that it makes a good learning project, too. When using pygame, we will draw each frame of our animation to an offscreen buffer. That is basically like an invisible canvas that exists in memory. This allows us to draw the scene piece by piece, and th...

Optimizing MPI Performance (Real Examples)

MPI jobs that run are easy. MPI jobs that run fast and efficiently — that’s where things get interesting. If your application scales poorly, takes longer than expected, or wastes CPU time, the issue is usually not the code itself… it’s how it’s running. That said, performance tuning is rarely about a single fix. The examples below highlight common issues and improvements, but in real-world HPC w...
