4+ day, 8+ hour ago   (1003+ words) Eu entrei na programação de cabeça no finalzinho de 2022. Não foi um caminho gradual, do tipo "vou dar uma olhadinha e ver se gosto", foi mais um "preciso muito seguir esse caminho" dito em voz alta pra mim mesma. Comecei…...

1+ week, 2+ day ago   (893+ words) We often confuse high memory capacity with intelligence or talent. Someone can recall formulas, APIs, historical dates, syntax, definitions, and entire textbooks—and we assume they are exceptionally talented. But here's the uncomfortable truth: Storage is not computation. A database…...

1+ week, 5+ day ago   (486+ words) No artigo anterior, vimos o desastre geométrico que acontece quando você troca o modelo de embedding do seu RAG de um GPT-1 para um DeepSeek ao longo do tempo. Os vetores vão parar em espaços latentes completamente diferentes. A busca…...

2+ week, 1+ day ago   (204+ words) A robot control loop repeatedly reads the state of the physical system, calculates a response, and sends commands to actuators. A basic loop is: For many robots, consistency in timing is as important as computational speed. Suppose a controller operates…...

2+ week, 5+ day ago   (282+ words) You ask a company to delete your data. In a normal system that is a database operation: find the rows that are yours, remove them, done. The mental model of “delete” that privacy law is built on — the GDPR’s right…...

3+ week, 2+ day ago   (607+ words) By Lino Avila | JX Planet X project | August 2026 JX N-Body Engine 0.1.0 is a reusable Newtonian propagation and numerical-validation toolkit written in Python. It grew out of the JX Planet X investigation, but its purpose is broader: to make high-precision N-body…...

3+ week, 3+ day ago   (372+ words) Before I wrote anything for VAToolstack, I spent weeks doing something most content sites skip entirely: I talked to 21 people who actually do this work. Not surveyed. Talked to, one at a time, about what their day actually looks like....

3+ week, 4+ day ago   (976+ words) Autonomous AI agents introduce a security problem that traditional application architectures were never designed to handle. They do not simply process data. They interpret instructions, execute tools, modify files, retain state, communicate with other agents, and increasingly operate for long…...

4+ week, 3+ hour ago   (1126+ words) Long‑context efficiency via attention and KV‑cache tricks Redesigning attention lets models handle far longer sequences without extra FLOPs. Linear‑time recurrent attentions such as DeltaNet expand hidden capacity, while Sparse Delta Memory adds a sparse addressing layer that…...

4+ week, 19+ hour ago   (635+ words) I was an experienced Software Developer, but in 2025, I made a decision that many people around me considered crazy — I quit coding. Not because I couldn't do it. Not because I was bad at it. But simply because I wasn't…...
