I was reading codebreakers and came across Joseph Mauborgne — so not only did this guy invent One Time Pad (theoretically unbreakable encryption) and played violin but was also I think a really cool team lead —

“Perhaps most important of all, Mauborgne’s intense interest inspired his men to outstanding accomplishments” - David Kahn, The Codebreakers

I think that’s pretty cool and tbh quite inspiring ✨

You probably weren't aware, but your #Linux crypt(5) supports the following #password hashing functions (in addition to some others):

• bcrypt ($2b$)
• scrypt ($7$)
• yescrypt ($y$)

You should definitely migrate to one of those password hashing functions over the risky sha256crypt / sha512crypt which is default on most distros.
