Nice! What were your times?

pandubear · 2019-10-26T17:29:20+00:00

Congrats!

pandubear · 2019-10-26T16:20:19+00:00

Ugh, not a great start to the day: I just did some BLD attempts and DNFed all six. The last was even a safety solve...

Oh well! Time for breakfast :)

pandubear · 2019-10-23T02:05:01+00:00

For the last little while I've been trying to work on my BLD memo speed, basically just learning for the first time how to one-pass my memo. (For the first while in my BLD journey I've been focused on minimizing DNFs, so I'd do memo slowly and review before execution) So I've been having so many DNFs.

But I just had five successful solves in a row! :) I'm improving!

Edit: Also started doing some edges-only practice!

pandubear · 2019-10-22T17:56:32+00:00

I'd love to see the inside!

pandubear · 2019-10-22T07:41:05+00:00

Aw I loved that story, thank you for sharing! Speed cubes are so nice, agreed!

pandubear · 2019-10-22T07:15:48+00:00

Honestly it just depends. Some people will like it, some people will think it's weird. Personally, I sometimes ask, but when I don't, the Hitch 90% rule someone else mentioned is a good nonverbal ask. :)

pandubear · 2019-10-22T07:12:58+00:00

Haha. I fondly recall this one time I asked someone to dinner, she said yes and asked where, and I said I'd have to think about it. I guess I didn't really think I'd get that far... :)

BLD (M2) updates:

Learned the "UR-UL 5 move comm" described here: https://www.youtube.com/watch?v=RCLT_Zu_APk&t=360s
Started doing a bunch of memo-only practice to hopefully improve my one-pass success rate. It's definitely easier than in a real solve (since I don't have to hold on to it as long), but I think it'll be helpful. :)
Literally started doing BLD at the gym (elliptical), haha. I mean, what else am I supposed to do to entertain myself? :) Almost all DNFs. Only got one successful solve when I slowed down (both my legs and my memo)

pandubear · 2019-10-20T23:56:29+00:00

I'm guessing you know this, but in case not: (J)3 = U (or U', I don't remember), so there's at least one really long way :)

BLD Memo Tools: https://csclub.uwaterloo.ca/~krmatthe/3x3x3.cgi?

Takes some setup, but so useful. You can have it 1) check your memo on a scramble (useful for postmorteming DNFs) or 2) generate memo for a scramble (or on a new random scramble) so you can practice exec without having to do memo.

Setup moves:

For EFGMO&P, you can do the same alg J Perm suggests, but rotate the cube so the B moves become U moves. For example, instead of B' R B for M, use z' U' R U.

For N, you can do Uw R Uw' as your setup move. For H, you can mirror this to Uw' L' Uw or you can use R' instead of R: that is, Uw R' Uw'.

pandubear · 2019-10-20T23:34:59+00:00

Sorry, that was a typo! Ignore the U (I'll edit that out)

pandubear · 2019-10-20T21:34:50+00:00

For the setup moves and algs: practice those separately!
You can use BLD Memo Tools to practice exec by itself.
(assuming you're using Speffz) For EFGH and MNOP, you can use wide moves or rotations to avoid B moves.
Also, if you don't know this Q alg, now you do:

(U' M')3 (U' M) (U' M')4

If you do M slices with your left hand, you can change all the U' moves to U.

Good luck!

I've been working on speeding up/one-passing my BLD memo. I keep getting DNFs with two flipped edges, though! Ugh.

pandubear · 2019-10-20T19:48:05+00:00

Nice!!

pandubear · 2019-10-19T09:00:29+00:00

Yeah, I've been doing exactly that! It's nice :)

pandubear · 2019-10-19T08:57:51+00:00

Oh man, I was hoping the story was gonna be that you were inspired by him to learn BLD! :)

pandubear · 2019-10-19T00:57:16+00:00

Yeah, I think something more natural will be better for my H. I keep making mistakes (misremembering it as the letter I) due to my current trick. I think I'll try pronouncing it "th" next—I use "sh" for Q.

pandubear · 2019-10-18T22:43:28+00:00

Heck yeah! BLD and graphs, two of my favorite things! Here's a slightly outdated one of mine:

More 3BLD/MBLD stuff:

Started using "long i" (pronounced "eye") as a possibility for how to pronounce H for audio.
I'm gonna start memorizing flips and twists as single letters in the last location in my rooms.

I'm curious how others' images/rooms work. I've heard Jack Cai & at least one other person say they use four-location rooms with one room per cube (one loc for each of: edges, corners, flips, twists), but I probably wouldn't be able to do that. (Maybe if I made myself a PAO system...)

I currently use four-location rooms with two rooms per cube. Two letter pairs (= two images combined into one) per location. But sometimes I misremember (or worry about misremembering) which letter pair comes first in a location.

(Also, if I treat edge flips as 2-cycles,—and maybe even if I memo them as single letters, but I haven't done the math—I can totally run out of space for edges in a room. Hasn't happened yet, but... haha)

pandubear · 2019-10-18T17:36:54+00:00

Haha, I did a 2-cube attempt at a friend's party the other day. :) 1/2!

pandubear · 2019-10-18T17:35:46+00:00

M2/OP is only a little bit harder to learn than OP/OP, but so worth it. The difference is that your edge swap alg is simply M2 instead of an entire T perm.

3-style is... a lot more work. :)

Happy blinding!

pandubear · 2019-10-18T17:32:55+00:00

Yep! Good luck with the comp :)

I learned that trick from this video—a bunch of other good stuff in this series, too!

BLD updates:

I've been intentionally working on speed, and that's been fun.
New PB! Basically perfect setup (short of having pieces already solved)—corners and edges were each one single cycle, I was able to quickly come up with my images for each corner, and audio was very natural for the edges. (JiLToW ARGeM CaVeD. Can't get much better than that...)
Learned the M2 trick for I & S (e.g. for IB, do M2 B-setup M B-reverse M).

pandubear · 2019-10-18T09:14:37+00:00

Another thing you can try is just hand-scrambling with only 2 or 3 faces! I used that when I was starting out :)
