My thirteen year old PC is holding up fine. I've replaced the disk (condition of me getting it; it was a disused Windows machine), installed Ubuntu, Debian, then Kubuntu, and upgraded the video card, but beyond that...basically as it shipped from Dell. The last BIOS update was 2013.
You'd have to use this version (not sure if they back-licensed old versions) but MIT would mean you wouldn't have to agree to that draconian licensing.
AIUI (I don't have any of this hardware) SteamOS is really meant for the Steam Deck; while there's "basic support" for the ROG Ally, it's not their focus. Bazzite seems to be quite happy to support everything, and AIUI it's frighteningly close to SteamOS (the same customizations, etc.)
It's not "we have SteamOS at home" - it's more like RedHat vs CentOS
As we know or a quick STFW will educate - the "airplane with red dots" refers to the idea that the planes that came back had damage indicated on them with red dots and so the initial idea was that the designers of the planes needed to armor those spots...
When it was really the case that the spots that weren't damaged were the ones that actually needed to be armored, because the planes that took damage there didn't come back.
In this case, the data that survived a selection process ("I just recommended this book that dovetails nicely") is the only data considered, when really all of the data needs to be considered.
I'm seeing this as "you're reading the data wrong" or more accurately "you're barking up the wrong tree"
(Not OP) it's a shorthand to use a company's stock symbol instead of the name, especially if you're worked in the financial industry, where everyone knows what you're talking about or can look it up very quickly.
