This tutorial walks you through building a production-grade, high-throughput REST API using Go 1.24’s new low-latency GC and Gin 1.10’s optimized router, hitting 47k RPS on a 4-core VM with p99 latency under 12ms. 🔴 Live Ecosystem Stats ⭐ golang/go — 133,662 stars, 18,955 forks Data pulled live from GitHub and npm. 📡 Hacker News Top Stories Right Now GTFOBins (136 points) Talkie: a 13B vintage language model from 1930 (343 points) Microsoft and OpenAI end their exclusive and revenue-sharing deal (872 points) Is my blue your blue?
