examples

Example code in different languages and technologies, for fun.

Language Examples

These directories were merged from standalone repos (now archived) using git subtree, with full history preserved.

Directory	Former repo
cpp/	muzammilar/examples-cpp
erlang/	—
go/	muzammilar/examples-go
js/	muzammilar/examples-js
python/	muzammilar/examples-python
rust/	muzammilar/examples-rust

Some Go modules still declare github.com/muzammilar/examples-go/... module paths; they build fine from their new location.

Systems

Databases, pub/sub, streaming and infrastructure examples, one folder per system.

To add or test a system, follow FORMAT.md: folder layout, Make targets, Compose and kind conventions, scaling, failover, benchmarks and README format.
