When you find ast-grep fine tuning valuable, wait until you find out how much powerful CodeQL can be 🚀 btw CodeBERT already has a finetuned version on AST

After experiment and running through all whole 2 chapters of @rasbt's Build a Reasoning Model book 📚 Now I have to wait till Spring 2026 for the rest of the chapters like Squid game 2/3 release 😂

I’ve been working on something new: 📚 Build a Reasoning Model (From Scratch). The first chapters just went live! (The book will cover topics from inference-time scaling to reinforcement learning)
Fine-tuning CodeBERT for secret detection dataset is so much interesting & lot of stuff to learn 😍 Looks like once you start playing with NN there is no going back 😇
Claude Code's GitHub integration is now generally available with a simplified API, ready-to-deploy templates, and support for more GitHub events beyond @-claude mentions.
Totally surprised! Google Pixel support team shipped a ~3 year old out-of-warranty pixel 6A replacement device in 3 days after confirming a battery 🔋 issue. And pixel 10 release is stunning 💥
"We know from chaos theory that even if you had a perfect model of the world, you'd need infinite precision in order to predict future events. With sociopolitical or economic phenomena, we don't have anything like that." - Nassim Nicholas Taleb
In building AI agents @cline , we've identified three mind viruses Mind Viruses are seductive ideas that sound smart, but don’t work in practice. 1. Multi-Agent Orchestration 2. RAG (Retrieval Augmented Generation) 3. More Instructions = Better Results Let's explore why!
You may think temperature=0 makes LLM responses deterministic, but this is actually false for several reasons! Unfortunately, non-determinism is especially painful when using LLMs as classifiers. What causes this, and how did we work around it?

Basically 7 insanely smart teams built Hackbots that fuzz binaries for vulns…. And they’re all open source. Zero exaggeration: this is a treasure trove for anyone building agents.

Any amount of intelligence can be overridden by: ego, insecurity, immorality, bad incentives, or impatience, usually in that order.
The perfect weekend article just dropped by @rasbt on gpt-oss architectures. It’s wild to see how fast these architectures have leveled up since GPT-2 in 2019. abs positional emb → RoPE GELU MLP → Swish + SwiGLU one dense feed-forward → MoE Multi-head attention → GQA …
