A Git story: Not so fun this time
https://blog.brachiosoft.com/en/posts/git
Linus Torvalds once wrote in a book that he created Linux just for fun, but it ended up sparking a revolution. Git, his second major creation, also an accidental revolution. It’s now a standard tool for software engineers, but its origin story wasn’t so much fun this time, at least for Linus.

A write-ahead log is not a universal part of durability
https://notes.eatonphil.com/2024-07-01-a-write-ahead-log-is-not-a-universal-part-of-durability.html
A database does not need a write-ahead log (WAL) to achieve durability. A database can write its long-term data structure durably to disk before returning to a client. Granted, this is a bad idea! And granted, a WAL is critical for durability by design in most databases. But I think it's helpful to understand WALs by understanding what you could do without them.
