Agents, context, and guardrails on a unified platform

Assistants that only suggest code are the easy part. The hard part is letting automation near production without turning every shortcut into a gamble—especially when the same stack already sprawls across dozens of tools and half-finished wikis. Same rules, same graph, same audit trail: humans and agents converge on one policy layer before production actions run. Actor Convergence: fragmented ...

The AI-Native Database Nobody Told You About: 5 Hidden Uses of Infinity in 2026

If you're building LLM applications and still reaching for PostgreSQL with a vector extension, you're leaving serious performance on the table. Infinity, the AI-native database from Infiniflow, has quietly accumulated 4,489 GitHub stars and is being used in production by teams who discovered what most developers haven't yet. @sama (Sam Altman) has hinted at infrastructure being the next bottle...

I Built a Threading Engine - I Need Results (Feedback)

I've been building TokenGate - an experimental Python concurrency engine that uses a token-based model to manage threaded tasks. No manual thread management, no futures, no ThreadPoolExecutor. Just a 3 line coordinator and single line decorators to manage all threading. It runs on Python 3.12 with the GIL effectively "gone". On my machine (Ryzen 7800 / RTX 4070 Super) I'm seeing 7.25x concurrenc...

66 Tokens Make a Diffusion Language Model Look Easy

A diffusion language model generates text by starting from masked or otherwise corrupted tokens and iteratively restoring them. In this MacBook Air M2 demo, that idea shows up in its smallest, most hackable form: a toy character-level model that learns to recover missing characters from Karpathy's tiny Shakespeare dataset. The GitHub project Encrux/simple_dlm really is small and direct. The autho...

I automated my entire job search with AI — here's the full stack I built

I automated my entire job search with AI — here's the full stack I built Manual job searching is genuinely miserable. You open LinkedIn. You scroll. You find something promising. You copy-paste your resume into their portal, tweak the cover letter for 20 minutes, submit, and hear nothing for two weeks. Then you do it again. And again. I got tired of it, so I built a tool that does the...

QIMMA LLM leaderboard theo nguyên tắc “validate trước, evaluate sau”

Giới thiệu Trong vài năm gần đây, số lượng benchmark và leaderboard cho mô hình ngôn ngữ tiếng Ả Rập tăng nhanh. Nhưng cũng như nhiều hệ đánh giá trong giai đoạn bùng nổ LLM, tốc độ mở rộng thường đi trước độ chặt chẽ của dữ liệu. Hệ quả là không ít bảng xếp hạng trông rất thuyết phục, nhưng nếu soi kỹ, điểm số của model đôi khi phản ánh lỗi benchmark nhiều không kém gì phản ánh năng lự...

Ten CLAUDE.md rules for Claude Code - four edit-time, six runtime

Forrestchang's andrej-karpathy-skills CLAUDE.md is four rules aimed at the moment Claude is writing code. They work. What they don't cover is the moment Claude is running. Once a Claude-driven pipeline goes to production, a different failure mode shows up: confident outputs, silent budget overruns, destructive side-effects, prompt injection via user input. These six extension rules are what I shi...

LLM-as-Reducer and the Case for Killing the AI Label

A live broadcast tool shouldn't die the moment the final out is recorded. Audiences stick around. They pull up YouTube for the post-game press conference that uploads 20 minutes later. They tune into podcasts, scroll Reddit threads, check what beat reporters and fans are saying on X. Your dashboard should meet them there. The problem is that post-game signal comes from five different places, each...
