There's a method entirely based on group theory, a version of the original computer algorithm created to solve the cube (the Thistlewaite algorithm) simplified for use by a human [1]. It iteratively solves the cube into simpler groups

Yeah my MoYu also has a face or two that sometimes desync. Really annoying. I have a basic case recognition feature, though no statistics are tracked there yet. I also have some code for tracking splits (only CFOP), though I haven't in

Cubeast looks pretty awesome, but it only works in Chrome, which is a non-starter for me. So a few months back I started my own Python/Qt app, which is roughly similar to Cubeast, but less features as of now: https://github.

I think I was a bit lucky, but solved today's (#8) optimally in a minute or two. Pretty cool puzzle, reminds me of this: https://blog.plover.com/math/24-puzzle.html

For a case like that, I'll use rectangular block mode--it's really fast and intuitive, so I'll usually pick that over :s/a/b/g if it's applicable. The whole thing would be something like <ctrl-v>5jec

The solution partitions the solution space exactly the way I want it to: it was designed for the site this thread is about. Obviously it doesn't work against an arbitrary adversary. My solution is static and doesn't take any clues

Yeah, I see how the quoting complications make CLMUL pretty hard to use (or just useless). I have a few ideas about how to deal with the quoting/escaping, and if I get some free time in the near future I'll try and code something

Thread's getting a bit old, hope you see this :) Referring to the OP, I'm not sure what exact dialect of csv they're using, but its quoting rules are nothing like Excel's: quotes are escaped with a separate character (po

Good points all around. Not sure what the OP's requirements are, but judging by their current code, CLMUL should do nicely (or they have a bug). And also, thanks for that example. Clearly I don't know CSV well enough--are quotes i

CLMUL in general is a bit weird to wrap your head around, but a CLMUL with -1 isn't too tricky: it's like a running 1-bit sum, or in other words, each bit in the result is the parity of all the bits up to that point in the multipl

I don't think that's necessarily (or even probably) true in this case, since the vulnerability only exists where attacker-controlled data gets logged. If a library is just using log4j for some diagnostic messages with no user data

zelda64.com was also the official website when Ocarina of Time came out, presumably because, at the time, the zelda.com domain was already taken by a porn site. That was an interesting discovery for 10-year-old me.
