Among the many hobbies that modern nerds pick up, one has recently become incredibly popular: making everything in your house dangerously unreliable by inserting a bunch of software where previously simple wires had sufficed. In this post, I describe how I replaced the wires between my lights and my light switches with some Bash.

Recently, the inclusion of libsystemd as a dependency of distribution vendored copies of OpenSSH server caused a bit of a scare. Not necessarily because of libsystemd. That being said, maybe NIH isn't that bad in some situations, maybe we shouldn't be so eager to add a dependency when a short bit of code is sufficient. So I wrote a short bit of code.

Recently I was writing a little code generation utility which took lots of positional arguments. I wanted to add two optional features to this utility, these options would take no arguments. I decided to use getopt but realised that this would make the code depend on POSIX, I liked the idea of staying dependency free so I quickly investigated really simple solutions for option parsing (without compromises) which would be equivalent to POSIX and GNU getopt.
