From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I quite liked how the original Linux fix for the Spectre-style speculative execution bug on Intel processors was called "Forcefully Unmap Complete Kernel With Interrupt Trampolines", but alas, in the interest of diplomacy it was renamed to "Kernel Page Table Isolation" (KPTI) rather than "FUCKWIT".
Doesn't feel like it was that long ago, but of course, all search results are dogshit in this new age: https://wccftech.com/intel-kernel-memory-leak-bug-speculative-execution-performance-hit/
I never really looked into what they were doing with KPTI.
Assuming it's accurate, that first one is a much better technical description, even if it was intended to spell FUCKWIT
