What else can you do with a Linux phone?

I've only had the Jolla C2 for a few days but I'm trying to make it my daily driver for a bit to see what it's like, but I'm most curious to see what capabilities I might be able to get by having a proper Linux phone available. With a terminal built right in, I should be able to add repositories and install other apps, so it'll be interesting to see what can be done. My next order of business will be figuring out how to install common desktop packages like ffmpeg or Distrobox on this device. Jolla C2 Community Phone Brand Jolla SoC

I tried a phone that runs actual Linux, and Android app support made it almost usable
Why make a better operating system in the first place?

There's no way I couldn't start this article without touching on the gigantic elephant in the room: the Windows Subsystem for Linux. It truly says something that, for all the benefits Windows may have over a typical Linux distro, Microsoft decided that one of the ways to make Windows better was to simply... put another operating system inside of it. WSL initially made its debut back in 2016, and since then, it has progressed significantly, going from a purely terminal-based tool to adding support for GUI apps, as well as adding support for systemd, a key component in many Linux distros. The fa

Every good thing in Windows 11 started as a third-party tool Microsoft eventually bought or copied
Who needs the help anyway?

Sitting out of a project that sounds as grandiose as the Open Gaming Collective may have seemed like a bad idea, but it didn't take long for CachyOS to prove otherwise. In early March, a report indicated that CachyOS had become the most popular Linux distro on ProtonDB, a platforms that tracks Linux usage on Steam. For nearly five years, that top spot had been held by pure Arch Linux, but CachyOS has grown massively in the last couple of years, and it accounted for 21.1% of Linux users on Steam as of this report. It's worth noting that Bazzite sat in fourth place at 9.5%. That should make it o

CachyOS skipped the Open Gaming Collective, and gamers rewarded it by making it the top Linux distro on Steam
