Currently just alpine with docker compose, but I initially wanted to use podman, this was before quadlets were a thing and I found it very cumbersome to configure the networking between containers, also recall having to use kustomize as an extra step, so I gave up and went with compose.

Now there are quadlets with podman, which seem to do everything I need but require systemd. I’d be happy to switch from openrc to systemd just for the sake of using podman.

I’ll finally be able to switch from docker compose to podman with quadlets on my server running alpine

GitLab LFS storage is mad expensive. I regret buying into it… We have an unreal engine project and the assets cross over 20GB, not raw assets mind you. I’ve self hosted perforce before and should have stuck with that

Forgejo has auto mirroring built in, it’ll periodically sync the repos you add. The disadvantage is you have to add them manually. Initially I wanted a list of my started github repos synced to my forgejo instance and just added them one by one. A simple cron job might be enough to do that, but last time I checked github didn’t have an API for fetching started repositories.

Isn’t VST pretty much a wild west anyway? I wonder how much is this really gonna help to standardize the tools/plugins

Mainly use it as a documentation search for APIs I’m not familiar with, or when I’m not sure what options there are to approach a problem. I work with unreal engine a lot, so I’d get a few pointers from an LLM first, then go read the source code of those APIs and inplement the rest myself.

I guess it can go both ways, but I’d probably put nixos under minimal and experienced branch

That’s a great analogy, I’m going to try to use it at my place, next time I need to explain tech debt

If the image metadata contains tags, they will be imported into immich as well. At least all my Google Photos tags got imported no problem.

ScratchMark sounds great. For an icon, why not an actual scratch mark across a few pages? You know, the typical 3 ripped scratches, maybe with a sneaky paw print in the corner of the pages.

Rider for Unreal Engine at work. Neovim at work/home for literally everything else (web, golang, python, zig). I have vscodium as well, a glorified config file editor basically.

It pretty much does, at least for all the apps I want to use I have no need to use fdroid. If not, maintainers should probably publish apks and have reproducible builds

Obtanium is also a good alternative btw
