It shouldn't be used as a marketplace, it should be used as a repository. You can probably find a lot of malware on GitHub, doesn't mean you go there to choose your text editor.
I never search the AUR directly, I only use it if some README tells me I can install their software via an AUR package.
From experience: Junie, and AI agent based on Sonnet 4, performs quite well. It can even write tests and fix them if they are failing.
Not saying the quality is great, but good enough eventually work and to pass as junior code.
Not sure how good OpenAI agent is, and if they used their coding agent Codex, and if they did then was it as-is or with some tuning? Not sure, they write it was "custom agent based on o3".
They write all,the contestants have the same hardware, but did the agent run on the given machine, or in the cloud? Human brain is like 20-40W, so let's say the upper limit given he has to move his hands - did the AI agent get the same wattage? I don't think so.
Why would they have to handle it? This is Rddit's choice, not the law. I mean, why would Redit decide it now? Does Feddit fall under the same act? Or is it something new?
Jira would be okay without needless amount of plug-ins, extensions, and dumb workflows one has to follow. Accidentally put it in the wrong state? Enjoy writing to someone who can fix it. Besides, it is slow as fuck and is getting slower with all the tickets (over 80k on our instance) it has to track. Search is shit, and it is shoving AI in my face on every step.
Plain Jira is not bad. In my second company that I work for, I set up OpenProject and it has been working flawlessly for about 5 years already, it can easily track GitLab commits, branches, and merge requests, and do basic time tracking. It has some nifty features like "budget users" when you want to do budgeting with a "ghost user".
There a million ways, and you will probably find tons of tutorials each different - Docker, Docker Compose, native install, VMWare, Kubernetes, Portainer, etc. I recommend starting with a clean machine - preferably with an attached monitor - and installing your favorite Linux distro (Ubuntu is among the easiest), getting Docker and Docker Compose running, and familiarizing yourself with these technologies.
Then you can start with a simple app like Paperless (document digitization), Vikunja (TODOs), BookStack (wiki), or PrivateBin (pastebin), getting it running and persist state over a period of time, then setting up a reverse proxy so you don't have to use IPs all the time (with just editing your hosts file to point a URL to IP of your machine), and then it is a free world.
Of course, having the whole setup secure, independent, and easily manageable is partially eyperience and partially understanding your needs.
You will probably even find whole ready-to-deploy git repositories that are easily configurable, so you can go with that too.
Also labor price is unmatched. Nobody would work for the wage they give to children in China, so you can't really go that much cheaper while not sacrificing safety.
Anything works really. Mint, Gentoo, Fedora, Arch all work - usually just need to install Steam and done, possibly install drivers using your package manager if it doesn't come pre-installed. Hell, you can even do SteamOS or something like Bazzite or Nobara if i remember correctly.
Given that you didn't specify any alternatives, I can vouch for Kagi. It has been working very well and they also have a family plan.
