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.

Almost half of international fintech services are running on COBOL
Banks, Insurance , etc. are ultraconservative as far as tech. They want ultra stable systems. I had an acquaintance that had a business reselling ATMs to banks. Banks had a hard time sourcing EOL ATMs or spares. I remeber a story about some specific 486s CPUs and SIMMs that sold for 1000s, due to not being sourceable new from any supplier, and being needed as replacements for certain ATMs
Banks and insurance companies are also scared shitless of something breaking during upgrades to systems that control billions in funds
