# Usage:
# Once you started git rebase --interactive master, and you are presented
# with the list of commit SHAs and commit messages, from Vim:
# - visually select all SHAs via "V}k"
# - launch git-rr: !git-rr
# - ...
# - profit! you now have the same info as before, just with the list of
#   filenames which changed with each commit, and can now move around

PayPal blocks copy/paste actions in their "change password" form, 
citing some irrelevant security issues as the reason. That's a 
load of crap, and they know it -- disabling copy/paste makes it a 
lot harder to use a decent password generator and a lot easier to 
screw up your pwd when retyping, especially if it's a long one 
(as it should be!).

So, here's the quick'n'dirty way to use an externally generated 
password in your PayPal account:

The Y Combinator

The Y Combinator is a classic lambda calculus construct that many people find baffling. Here's my attempt to explain it as clearly as possible (no promises!). Familiarity with Haskell syntax is assumed.

The problem we're trying to solve is how to write an anonymous function (a "lambda") that is recursive. Normally, if you want to write a recursive function, it looks like this:

fac n = if n == 0 then 1
        else n * fac (n-1)

YubiKey for FIDO2 Auth on WSL2 (Ubuntu)

What?

I got my hands on a new YubiKey 5 over the weekend. For those unaware, this is a pretty well-known security key which provides options for hardware authentication using a variety of different protocols (e.g. FIDO2, OpenPGP etc.). I was keen to try this out for authenticating with GitHub and also handling SSH credentials when accessing servers I'm running on my local network.

The problem however, is that I'm a pretty heavy WSL (Ubuntu) user and needed something which plays well in that environment. I didn't think about it too much when I initially ordered the YubiKey, but worked out over the weekend that getting a USB device (particularly a security key) to play nicely with WSL, isn't exactly straight forward. So, I did a write-up of the steps I ended up taking for others (or myself) to refer back to.
