In the spirit of learning by doing, I decided to implement a simple blockchain
server. More work remains, but I'm tired after working on this for ~2-3h. I'd
like to reimplement this from memory using a statically typed language like
Haskell. I'd also like to implement node
discovery (https://en.bitcoin.it/wiki/Satoshi_Client_Node_Discovery) because
that is still something I don't quite understand. But I'm signing-off for
now...

I think this is a form of symmetric encryption where the passphrase (e.g. "ICE")
is repeated (e.g. "ICEICEICEICEI...") until it matches the length of the
cleartext string; after that, the two byte-strings are XOR'd against one another
and then encoded as hexadecimal creating the ciphertext.

Create a frequency table of alphabetic characters by reading each character in
"Alice in Wonderland"; use this frequency table to score cleartext when decoding
ciphers.

Angle-bracketed references are a Nix anti-pattern, and thankfully this
repository enforces this as a standard.
TL;DR:
- Drop angle-bracketed references
- Change `briefcase` -> `users.wpcarro`
- Fix any resulting regressions
- Fix //users/wpcarro/tools/simple_vim
- Mark //users/wpcarro/boilerplate/typescript and related projects
as broken
- drop .skip-subtree file, enabling depot CI
