My post on “Weird” F2L is the most viewed on this site, and features the most popular video on my Youtube channel — with continuing thanks to CBC! So, I decided to copy the same format to showcase three more tough (at least for me) F2L cases. It turns out that these actually are easy cases. It’s just that the “intuitive” approaches are clunky, and the easy approaches non-intuitive.
Here’s the video tutorial, followed by table contrasting my old (intuitive) approaches against these improved ones:
I had planned on posting a two year cubeiversary video this weekend, it being almost exactly two years from the first time I solved a Rubik’s cube. It was going to show a 30-second solve, before self-deprecatingly mocking myself for not really improving much this year. Yes, my technique is better. Yes, I know more algorithms. Yes, I’m more consistent. But my cross still sucks and my speed just isn’t falling much. Oh well. I never proclaimed to be fast, and even anointed this blog as one for the mediocre.
Well, instead of waking up and editing the video, I found myself laying in bed puzzling over why I had 400 emails (almost all from Youtube). I finally realized that CrazyBadCuber had done one of his Crazy Bad Promo videos featuring my youtube channel! Sweet! Hundreds of new subscribers! Here’s his video:
I’ve always thought that my video production and blog quality both eclipsed my cubing skills. There’s a bias against slower cubers, and I figured I wouldn’t get much attention until I sped up. Continue reading →
Every once in a while, my hobby intersects with my profession. That was the case a year ago when I wrote about the controversy between Dayan and Seven Towns over the latter’s (largely exaggerated, I believe) position that it had a copyright/trade dress claim against any cube maker using the standard yellow-white/red-orange/blue-green color scheme. And it’s the case again now, with my recent project to decorate my new office. I figured that the lawyer who deals with patents by day and speedcubes in his free time might as well have some topical art.
I downloaded a variety of cube related patents, ranging from the very first related patent of which I’m aware (from the 60s), the Japanese magnetic 2×2 patent from the 70s, the Hungarian and US Rubik patents from the early 80s, the (in)famous Verdes V-Cube patents, and the (relatively) recent Dayan ones. In Photoshop, I assembled them into a composite with the abstract pages and key diagrams, had it printed at 24×36 by Kinkos (for $4.50), and framed it (via Aaron Brothers for $35). Voila! Legal-cube-nerd art:

It’s been 14 months since I wrote about more advanced cross techniques, which is only slightly less long than I’ve been at this cubing thing altogether. At the time, I was thrilled just to move on from the beginner’s method of forming a daisy on top. Memorizing the cube’s color scheme seemed like an accomplishment.
A year-plus later, I’m stuck at around 35 seconds. I’ve learned all 21 PLLs, have gotten pretty fast at two-look OLL (with a handful of OLLs one-lookable), and am competent with F2L (fast, but with lots of hunting still). But my crosses are still really clunky. Time to start focusing on the cross.
To set a benchmark, I did 5 Ao12s of just crosses. I spread out the sessions to make sure they were pretty accurate representations. Although there are a few stray bests, the 60-cross average was 6.75: Continue reading →
Go ahead and stream the below as your read this post. It’s my strained attempt to find some topical background music consistent with the post’s forced title. Maybe it’s just the introspection of turning 36, but it’s fun to hear an updated version of a song* that we used to listen to in high school.
So, I received my Shengshou 5×5 yesterday from amazon. I’m not really into higher order cubes, and certainly not into speed-solving them. But I guess that curiosity got the best of me. I wanted to test my theory that a 5×5 actually would be easier than a 4×4 for want of parity issues. I *hate* 4×4 last layer parity — with its long and confusing algorithms. Two 5×5 solves in, my theory seems mostly right.
