Inside PGO

In the previous article , we made Go code faster by changing how it computes. SIMD lets one CPU instruction work on several values at once, and the simd/archsimd and simd packages give Go access to it. Our dot product ran about 9 times faster, but the code got a lot harder to read. At the end, I promised another route to speed, one where you don’t rewrite anything. That route is Profile-Guided Optimization (PGO). You record a CPU profile of where your program spends its time and give it back to the compiler, so it can work harder on the code that is actually hot. Your source stays exactly as it was. We briefly saw it in the IR post , and today we’re going deep into it.

Learn Vector Databases for Beginners – Embeddings, Similarity Search & ChromaDB

A vector database stores data as lists of numbers called embeddings, which lets it search by meaning instead of matching exact keywords. It's the piece behind a lot of recommendation systems, RAG apps

10 Best AI GitHub Repositories to Supercharge Your Agent

GitHub là kho lớn nhất chứa công cụ AI miễn phí nhưng phần lớn lập trình viên chưa khai thác hiệu quả. Các agent như Claude Code thường được cài đặt mà không tận dụng được nguồn tài nguyên phong phú trên GitHub. Các kho lưu trữ AI hàng đầu như LangChain, LlamaIndex hay AutoGPT cung cấp framework mạnh để xây dựng agent thông minh hơn. Việc kết hợp các công cụ này có thể tăng đáng kể khả năng xử lý và tự động hóa của ứng dụng AI.

Bài viết này giúp bạn khám phá 10 kho GitHub AI mạnh nhất để tối ưu hóa khả năng của trợ lý lập trình.
