Luckily I bought my extra 32G of DDR4 (now have 64G) used a while ago, only paid like 80€ for it. I remember back in like 2018 or so when I originally build this PC I got 4x4G DDR4 for like 160€ when prices were also crazy.
AFAICT this is dead (no updates in four years) and "alpha software...only recommended for production use cases with careful testing, and if you are willing to contribute fixes or to work around issues you will encounter." Unfortunate, because it's pretty cool.
"We are adjusting our engineering priorities for RHEL for Workstations and focusing on gaps in Wayland, building out HDR support, building out what’s needed for color-sensitive work, and a host of other refinements required by Workstation users. This is work that will improve the workstation experience for Fedora as well as RHEL users, and which, we hope, will be positively received by the entire Linux community."
At the moment I use only C and the various language of the GNU build system. But in the past I used C++ or a personal project and before that I did some smaller projects in Ruby, PHP, Python, Javascript and HTML (with CSS).
