Cloudflare built a wall of lava lamps to help generate it.

eMudhra's compromised CA private key was literally "4".

The 16 digits on your credit card aren't all data.

One is a checksum calculated from the others to catch mistakes before a transaction is even attempted.

The surprising part: billions of cards use a weaker algorithm despite stronger alternatives existing.

A jack of all trades is a master of none, but oftentimes better than a master of one.

uuid - random unique identifier
uuidv7 - sortable time-based uuid

AWS US-EAST-1 is down, and taking a chunk of the internet with it.

Happy Diwali, I guess.
