Possibly the worst way to encode json in C?

% emcc example.c -o example.js -s DEFAULT_LIBRARY_FUNCS_TO_INCLUDE='$UTF8ToString,$stringToNewUTF8

% node example.js
JSON: {"name":"Captain Pants","id":0}

# 'gem list -i foo' will print 'true' if a gem is already installed. 'false' otherwise

GEMS=clamp rake

# From the GEMS list, generate a list of make targets
TARGETS=$(foreach gem,$(GEMS),gem-$(shell gem list -i $(gem))-$(gem))
build: $(TARGETS)
build:
	@echo "=> OK to build"

What?

Sometimes tar files have tar files, and it might be nice to read the contents of some files several layers deep. Here's how we can do it with Ruby and Python3 with no external dependencies.

Podman save

We can create a layered tar file (a tar file containing other tar files) using docker save or podman save

% podman save fpm-ubuntu-18.04 -o test.tar

Partitioning

Partitioning is something I do once a year and never remember. Arch's docs have great reference guides, but I just want to move on with my life without reading too much docs. This aims to simplify my partitioning experience.

fdisk /dev/<disk device>
