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 wish I could grep my car keys sometimes.
Back in the 80s/90s there were keyrings that would play an alarm if they heard a whistle at a particular frequency. You're basically playing Marco Polo with your keys.
I assume they lost popularity because the batteries tended to run out at inopportune times. Batteries are better now. Maybe it's time those things made a comeback.
I remember those! I think the comeback version is the Tile or AirTag but I'm too old to hear them beep.
