Sometimes I wonder what actual programs Linux permanents use on the daily.
For me it's the usual stuff like Firefox and Thunderbird, plus chat programs running constantly, with ssh consoles, VM managers, and text documents sitting in the background. Depending on which project I'm working on at the time I might be using GIMP, OpenSCAD, developing circuit boards, printing 3D models, writing arduino code, designing model train layouts, managing photographs or using kstars to run my star tracker. And there's the more mundane stuff like having LibreOffice and PDF docs open, playing music, or watching a downloaded TV show. I really get into a lot of different projects so from month to month there will always be something different running on my desktop.
I did finally break down and order a newer LGA1155 motherboard so I can bump up to 32G of memory, should be here tomorrow and then maybe I won't run so dangerously close to running out of memory all the time. Having to wait half an hour while firefox does garbage collection really sucks.
Oof how much space do those Minecraft instance take up??? My biggest usage is from Firefox, usually takes about 10GB of memory on my 16GB systems, but I run a lot of heavier stuff like building 3D models in the rest of the available space. I'm waiting on a replacement motherboard so I can upgrade to 32G though.
