euler VS ppp_thing

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.

I wrote a PPPoE client with failover so I can keep the session even when one of my gateways fails or is rebooted (this lets me do regular maintenance without interrupting my internet connection); I put it on github[1], but I doubt anyone will use it. I hope there are few people left with the scourge that is PPPoE, and my OS choice means many people would need to switch OSes to use it, so yeah. Also, I don't care to make it easy to use or to promote it, really. (I've mentioned it once or twice and did a Show HN that got less than ten votes, which I kind of expected).

I've also got my personal (network) monitoring software, some 'IoT' stuff to capture temperature and humidity data around my house, and I'm working on a ESP32 based alarm clock pulling data from iCalendar.

I just published https://github.com/russor/ppp_thing which lets me (and maybe you) failover my PPPoE session between two FreeBSD hosts, so I can do regular maintenance without losing my IP or impacting TCP sessions.

I used to let my DSL modem handle PPPoE and NAT, so failover was easy, but found out fragmented IPv6 crashed the leased modem, and the replacement modem also sucks, so bridge mode + a custom PPPoE client (but from netgraph pieces) it is. Sadly useful in 2021, because PPPoE is somehow still a thing.
