This repo contains my notes on working with Go and computer systems.
A personal learning notebook for Go, covering language basics, concurrency, data structures, algorithms, design patterns, and a handful of popular libraries like gin, gorm, and grpc. It's organized as runnable code examples paired with links to official docs and blog posts. This is a study repo, not a library — you clone it to read and run, not to import.
The concurrency section is genuinely useful — ping_pong, worker_pool, mutex, and waitgroup examples are all self-contained and testable. The design patterns section links each pattern to both a Go implementation and a real-world 'best practices' reference in the same repo, which is a better teaching device than abstract examples alone. The gorm section covers PostgreSQL-specific types (jsonb, int8range arrays) that are rarely documented anywhere. The interview Q&A at the bottom is honest and accurate — the answers on nil, string immutability, and map ordering are all correct.
The repo is clearly a personal notebook that was never finished — dozens of algorithm and pattern entries are placeholder 'todo' links pointing to readme.md, including DFS, BFS, Dijkstra, Observer, Command, and half the behavioral patterns. Last pushed May 2024 and the go.mod files are scattered and inconsistent, so not everything will build cleanly. The 'awesome-go' section is a grab-bag with no explanation of why each library was chosen or what problem it solves — it reads as a bookmark list rather than a guide. There are mystery files in the root (WHFGRPTT, YCCSNVFS.cvs, TYPE.pprof) with no explanation, which is a minor but telling sign of housekeeping debt.
