Content warning: tech, Ubuntu, sudo

Yesterday, I setup Ubuntu 26.04 for using it with the RTX A4000 GPU (I have the impression that Ubuntu is a first-class citizen for machine learning stuff with Nvidia). Today, I spent far too much time to find out why my FreeIPA provisioned account can't `sudo` on this machine.
It's `sudo-rs`. `sudo-rs` can't really sssd, nss or pam or whatever it is that usually tells `sudo` that a user is allowed to `sudo`.
Solution? `sudo update-alternatives --config sudo` and then…

Got the desktop-turned-VM-server added to the scopehal CI cluster.
I migrated the two Ubuntu LTS builder instances over to it, and added a third one so now we can run the regular Ubuntu CI, the asan/ubsan build, and the static analysis pass concurrently.
This box has a Xeon 5320 which is a bit slower than the 8362 on the main VM server, and has only 128GB of RAM rather than 512. But the compute-to-memory ratio is actually higher so after a bit of iteration I settled on 16 vCPUs a…

A very, very obscure nerdy cool thing:
When installing Ubuntu, you can choose to set up ssh -- and there's now a feature where it downloads your ssh keys from GitHub! Just give it a username.
This may just be with Ubuntu Server, but it's really nice, since you can install ssh without password auth and never need to actually log into the machine from the terminal to import ssh keys, or allow passwords and then later turn them off.

Pretty strong consensus in the replies to just use Debian.

New on #blog (this time with quotes from Fedi): "Why Gentoo?"
#Gentoo is perceived by the wider public, the non-users. What probably stands out most is compiling. Almost everyone who heard of Gentoo knows it has something to do with compiling everything. And why are we doing that? Well, besides being hardcore, the common sentiment goes for performance. So yeah, Gentoo users must be some kind of hardcore ricers who try to squeeze every last bit of their system performance.
To be honest, I don’t think that’s a good way to describe Gentoo. Yes, compiling is at the core of it. But performance? I don’t think so, at least not in the obvious, -O9999 -fzomg-fast way. The world has moved on, CPUs have gotten faster, optimizations have gotten smarter, and distributions have started optimizing more aggressively. Optimization-wise, I suspect your average Ubuntu package with generic optimizations may be no slower than the equivalent Gentoo package fine-tuned for your CPU. And if it’s not, then it probably won’t make a real difference anyway.
There’s much more to Gentoo than that. Yes, some of it comes from building from source: the flexibility. But a lot of it comes from the wider Gentoo philosophy, the philosophy that brought us all together. The idea that Gentoo is the distribution we’re making for ourselves and people who enjoy Gentoo. So if I were to make a few arguments for Gentoo, I’d focus on that. And this is what I’d like to do here.
