euler VS sim

I created a simple command line utility [1] to convert between rotation representations. If anyone has ever dealt with 3D rotations (e.g., euler angles, quaternions, rotation matrices) you probably know that it can be frustrating to know what conventions people are using, especially with euler angles (e.g., intrinsic, extrinsic, passive, active, etc.). So I made a tool where you can explicitly set those conventions with explanations on what they all mean.

I regular refer back to the README myself or test out some conventions with the tool.

Also became a fun learning experience about terminals.

I wanted to use GMail from a fast cli that used the native gmail API.

I wanted to download concurrently and according to patterns. Ok, so honestly this one probably exists somewhere in a form that I would like, but I couldn't find it.

I wanted multi-party authorization for sudo, and couldn't find one.

People kept using gettimeofday, so this is part of my compaign against it. (see https://blog.habets.se/2010/09/gettimeofday-should-never-be-...)

I worked in mobile core networks, and wanted a "ping" that used the GTP protocol since that won't be firewalled.

I wanted my bash scripts to have automatic indentation, while not sacrificing buffering latency and such.

I wanted a simple tool to audit my TLS certificates for expiry.

I was travelling to China on vacation and wanted a VPN out that would be unlikely to be blocked by the great firewall. Ok, so there are many VPN-like tools for getting through the GFW. Maybe it was just an excuse for me to write it. Honestly ssh -D would have likely worked just fine. It's being used by the keymaster project now though, so maybe it did something right: https://github.com/Cloud-Foundations/keymaster/blob/master/d...

I wanted to lock down SSH to anyone who doesn't have a secret key (and portknocking is usually ridiculous). Why not use TCP MD5 for it? https://github.com/google/tcpauth
