2022-01-08 r/3556 feat(wpcarro/scratch): create a proof-of-concept blockchain serverWilliam Carroll3-0/+286
> You cannot get educated by this self-propagating system in which people study > to pass exams, and teach others to pass exams, but nobody knows anything. You > learn something by doing it yourself, by asking questions, by thinking, and by > experimenting. > - Richard Feynman 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...

2022-01-08 r/3548 feat(wpcarro/cryptopals): Support repeating key cipherWilliam Carroll1-0/+16
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.

2021-12-15 r/3249 fix(wpcarro/nix): Remove <briefcase> referencesWilliam Carroll3-10/+9
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 Change-Id: I7153cbabafa617bfd6b199370cbec65cb75441f6 Reviewed-on: https://cl.tvl.fyi/c/depot/+/4325 Tested-by: BuildkiteCI Reviewed-by: wpcarro <wpcarro@gmail.com> Reviewed-by: tazjin <mail@tazj.in> Reviewed-by: grfn <grfn@gws.fyi> Autosubmit: wpcarro <wpcarro@gmail.com>
