This is a general discussion thread. Anything is welcome!

Any exciting plans for the week? Any new PBs? New interesting puzzles?

    I started learning 3-Style and I made my own tool to parse Jack Cai’s sheets and create flashcards for the algorithms. I even made it generate the algorithms that Jack Cai marked as “inverse of …” by inverting said algorithm. Since it’s best to start with pure commutators, I made the tool replace all appearances of pure commutators other algs with the pair name. I think it’s very useful, much more intuitive and makes learning much faster. Hopefully I’m able to learn all of 3-Style before uni break ends.

    (Btw: I posted on the last discussion thread but it doesn’t seem to show up. I hope this one does)

      Sounds fun. I still don’t completely understand commutators so I never learned 3-Style. What method did you use before and what were your times?

      Strange. We did have a lot of issues at lemmy.world yesterday so maybe your post got caught up in that.

        I still don’t completely understand commutators

        Some algs can be scary, but the mathematical principle is really easy: if you do X, and then X’ the cube is back to its solve state. When there is a face where there is only a tiny bit of change, let’s say a corner twist, if you turn that face after X, by doing X’ you will solve the rest of the cube, and instead of twisting the same corner, you’ll twist the corner that is where the twisted corner was.

        An example of corner twisting.

        An exemple of corner swapping

        An explanation where it ticked for me: https://www.ryanheise.com/cube/commutators.html

        If you are more a video person.

        Doing non-wca twisty puzzle, commutators are a must.

        That’s also the case for patterns on big cubes.

        My PB is 3:07 with M2/OP. I’m going against the usual recommendation of “practice a lot of memo before learning 3-Style” but I’ve also read a few comments against doing that saying to just start with 3-Style immediately. Also knowing full 3-Style just sounds amazing.

        Do you do BLD too? What are your times and method?

          I don’t do BLD. I learned it once a while back because I wanted to get an official time, and I managed to get a ~7 minute time at a comp. Since then I’ve never really practiced. I did OP I believe. I looked up 3-Style because I thought it was interesting but haven’t spent any time on it, or on understanding commutators.

      Nice! Will you publish your tool?

      I learned OP/M2, and managed some 4-5minute solves. Even though I understand commutator and most 3style algs, it’s too much algs for me.

      Keep us posted on your progress!

        Nice! Will you publish your tool?

        Probably! But I’m still trying to figure out how to organize it all. I also discovered more algorithm sheets (probably should have started by doing that research before parsing Jack Cai’s sheet). I’m trying to make it as general purpose as possible and also trying not to confuse myself while learning.

        Also it’s hard to reason about the best way to learn when I don’t know much yet (which leads to me implementing some interesting YAGNI), but I’ll update the tool as I go and maybe when I’m done/happy enough I’ll publish it. It’s all in Python though (to deal with the sheets via Pandas) and I think it’s not ideal because most cubers prefer online webapps AFAIK.
