True, but there are also some legitimate applications for 100s of gigabytes of RAM. I've been working on a thing for processing historical OpenStreetMap data and it is quite a few orders of magnitude faster to fill the database by loading the 300GiB or so of point data into memory, sorting it in memory, and then partitioning and compressing it into pre-sorted table files which RocksDB can ingest directly without additional processing. I had to get 24x16GiB of RAM in order to do that, though.

A Quiet Place (but with farts)

In my experience, nouveau is painfully slow and crashes constantly to the point of being virtually unusable for anything. The developers agree, as in the last couple months nouveau has been phased out of Mesa entirely. More recent Mesa versions now implement OpenGL on Nvidia using Zink on NVK, and the result is quite a bit faster and FAR more stable.

If your distribution currently still ships a Mesa version which uses nouveau, I would personally recommend you just stick with the Intel graphics for now.

Based on that plus the various other mistakes, my guess is that OP's native language isn't English, but probably one of the many languages which uses masculine pronouns as gender-neutral, and they're just doing a literal translation from their native language.

I wouldn't ever criticize women for being wary of men by default, but I would criticize someone for comparing me (and all other men) to fucking Musk. There is a difference between saying "enough men are dangerous that I should assume they're always a threat" and "all men are the same as one of the most despicable people of our time".

what a horrible day to have eyes

Aside from checking the kernel log (sudo dmesg) and system log (sudo journalctl -xe) for any interesting messages, I might suggest simply watching for any processes which are abnormally high while the system is running slow. My initial approach would be to use htop (disable "Hide Kernel Threads" and enable "Detailed CPU Time"), and seeing which processes, if any, are eating up your CPU time. The colored core utilization bars at the top show how much CPU time is being spent on what: gray for disk wait, red for kernel, green for regular user process, etc. That information will be a good starting point.

Sadly, Visa and MasterCard are well-established as the ones who get to decide what is and isn't acceptable online.

Again, that would be TIFF. TIFF images can be encoded either with each line compressed separately or with rectangular tiles compressed separately, and separately compressed blocks can be read and decompressed in parallel. I have some >100GiB TIFFs containing elevation maps for entire countries, and my very old laptop can happily zoom and pan around in them with virtually no delay.

Real or Cake?

There is a reason why TIFF is one of the most popular formats for raster geographic datasets :)
