A bunch of quite useful tricks. Some I already used and other's are new. Here are the headings:

1. Forward Yubikey Agent
2. Reuse connections
3. SSH straight into tmux
4. Alias commonly used hosts
5. Do not add testing stuff to ~/.ssh/known_hosts
6. Make connections last longer
7. Canonicalize hostnames
8. Yubikey and GitHub, without touching it every time

I find it quite helpful to create a persistent connection to github. It greatly reduces my connection latency for pushing and pulling.

A Preprocessor Iceberg Meme on C preprocessor magic. Similar to "The Cursed Computer Iceberg Meme".

The basilisk collection (also known as the basilisk file or basilisk.txt) is a collection of over 125 million partial hash inversions of the SHA-256 cryptographic hash function. Assuming state-of-the art methods were used to compute the inversions, the entries in the collection collectively represent a proof-of-work far exceeding the computational capacity of the human race.

This is a grand work of fiction.

The author has another fiction on the concept named "Clairvoyant Computing": https://suricrasia.online/unfiction/CSC218-Software-Precognance.pdf
