Back during the summer of 2019, I worked a bit on the Coq kernel. At the same time, I posted a lot of toots on Mastodon about whatever random problems I was encountering. I’ve decided to collect them here, as it might just be that some of these will be useful to me again at some point.

Exam season has ended, and so too must this story. There are a lot more things I could self-host, but I’ve come to a point where I’m comfortable with the services I’ve set up for myself, and other ideas have larger scales and likely would deserve their own posts (setting up a mail server, for instance).

We are now in the middle of the exam season. What better time than now to set up file syncing and a personal Git host?

Exam season is coming up now, so naturally I’ve decided to spend my time setting up a home server. I’m hoping to eventually be able to replace Google Drive with a self-hosted instance of perhaps NextCloud or SyncThing, but we’ll start small first. I’ve installed Ubuntu Server 16.04.4 LTS (Xenial Xerus), which was sufficiently straightforward that I won’t elaborate on it except to say that using an LVM caused me to be unable to boot into the OS, so don’t do that.
As with Day 18, today’s problem involved running a custom assembly program. However, as stated in part b, the program run with a = 1 is much too inefficient to run directly. Whereas with 18 you could simulate a machine in whichever language you choose and finish running the program in a reasonable amount of time, this problem requires deciphering what the program actually does, then optimizing it. We begin with the input (whose real values I won’t bother with hiding):
My solution for star 2 can be found here, but without the four pages of diagramming I did to get there, it’s largely indecipherable, so here’s some explanation on the mental process.
