A simple overview of Zig's `std.log` for Zig v0.12.0 or higher

Logging functionality that supports:

If a log message should be printed is determined at comptime, meaning zero overhead for unprinted messages (so just leave the code peppered with debug logs, but when it makes sense scope them; so downstream users can filter them out)
Scoped log messages
Different log levels per scope
Overrideable log output (write to file, database, etc.)
All the standard std.fmt formatting magic

Basic Usage:

Fabric/Quilt Server Optimization

This has updated for 1.20.4, all of the optimization mods mentioned here are compatible with each other and don't affect vanilla behaviour by default.

Mods

Common

export OPT=/opt
export BUILDS=/some/where/mini_linux
mkdir -p $BUILDS

Linux kernel

Parallel Distributed SHell (pdsh)

Similar to ansible command but allows you to use any command that will work in your shell. Not tied to specific configuration management tooling, just SSH and your default shell on remote systems. Just works. I <3 it :)

What does it do?

Runs commands across potentially many machines. Allows you to organize your servers/VMs/instances into groups very easily.
