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 →
Dude, I have the best idea. We’ll, like, put a whole bunch of, uh, multi-color high-intensity LEDs on like a square building and it will totally look like a Rubik’s cube when it lights up. Like a million throwies got stuck on the building in a totally organized way — like the most regimented rave on the planet. And, man, we’ll use one of those magic 3D printer things to make a cube with room for sensors and trick it out with an Arduino kit. Oh oh oh…a bluetooth modem, too. Duh. And then we’ll make the cube talk to a computer that talks to another computer that’s connected to the building, like a friggin’ twenty-first century game of operator. And people can like use the cube to solve the building, man. And it would would be epic — serious nirvana sublime sh#t, dude.
There are limits to intuitive F2L (so-called). There, I said it. Again. Yes, the concept of pairing edges and corners in the top layer before insertion is elementary, and, in many instances, you can intuit just how to do that — splitting pairs, using empty slots, etc. But the solution to certain cases is far from intuitive. Which is to say that purely intuitive approaches might work, but inefficiently (too many moves, unnecessary cube rotations, etc.).
Cases 23 and 24 are prime examples; their cousins, 11 and 12, are close seconds. Having spent a few days on these four cases (watching videos, looking on the speedsolving wiki, etc.), I found much better solutions than my “intuitive” ones. (With the exception of #23, which I had learned from Andy Klise’s excellent F2L Cheat Sheet.)
The improved cases are demonstrated in the video below and summarized in the chart that follows it. The cube is an F2L Practice Cube, basically a Maru Cx3 with only the bottom two layers stickered. Anyone learning F2L should un-sticker the top layer of a cube to prevent distraction and increase F2L focus.
I’m a bit of a shutterbug, with a couple nice SLR bodies and a collection of Canon L glass at home. Once upon a time I had a really nice video camera that we used to film the kids doing kid stuff — you know, first steps and all that jazz. Well, the passage of time made that that camcorder seem prehistoric. Time to get a new one to record the goings-ons with the kids....
Enter a Canon VIXIA HF R400, a compact camcorder packing a big punch on a digestible budget. This blog is an unintended beneficiary.
As the owner of an SLR that falsely-claims noise-free 3200 ISO shots, I assure you that I approached the R400′s low-light claims skeptically. Less skeptical was I of the solid slow-motion claim, based on the option of recording at 60fps. I tested both in this quick video:
The Mouse OLLs (##3, 4) are hard. Not so much their execution (certainly the Sexy Move variants aren’t all that bad), but orientation. Where does that corner go? Top-right? Bottom left? And what about that side with just the un-oriented edge? Which is Mouse and which is Anti-?
Having concentrated on these OLLs quite a bit, I now no longer mind them. Here’s a simple table and video tutorial — its soundtrack a tribute to Lou Reed, RIP — followed after the jump by further explanation.
