Blimey.

Why not post it then?

Last I heard, he planned to attempt 46 cubes.

You sure?

You lied to us. You bastard.

 

[Berd]

You lied to us. You bastard.

He DNF'ed his second attempted, he could of gone for 46.

I reduced my 40+minute video to 9 mins today. Hopefully it's useful to someone!

Yes, this is definitely helpful. Thanks.

OK so I need to clear up something about commutators, about knowing whether to perform the interchange first and the 3-move insertion or vice-versa.

From what I understand so far I see where the non-interchanging piece needs to go and either perform the interchange with where it needs to go or insert it into one of the interchanging pieces. Am I wrong, what other ways are there to do it, and how do you guys just 'know' what to do?

I think of it as seeing where I can insert the non-interchanging piece onto the interchange slice. Let's say pieces A and B are on the interchanging slice, and piece C is the lone piece (the one to insert).

If I can easily insert piece C to the spot where piece A is, and I have the cycle (CAB) then I would do
[insert C to A, interchange A and B] as my commutator. Note that [X,Y] means the commutator X Y X' Y'.

If I can easily insert C to the spot where piece A is, but I have the cycle (CBA), then I don't want to try to find a different insertion that sends C to the B location instead. I would rather just move the piece in the B location to the A location, since I can easily insert C to where A is. So if I can insert C to where A is, but the cycle I have to do is (CBA) then I would do:
[interchange A and B, insert C to where A started (and where B is now)]

Notice that I always insert to the same place (where A started). I insert first if C actually goes to A, and interchange first if C doesn't go to A, but goes to B instead.

I just realized something nice:

21.19 is the world record for memorizing a deck of cards.
21.17 is the world record for 3x3 bld

It's a shame they're not the same amount of information...

Why is half of that site in German when English is selected?

 

[Stefan]

Why is half of that site in German when English is selected?

Because Germany is the best!

(Not really joking, we're half the top 10, including #1 and #3. But really it's probably because the site is made/run by a German, though that in turn probably does have something to do with the German history and strength in the sport)

Yesterday I realised why I was DNFing so much while doing corner comms.

I WAS CORRECTING FLIPPED CORNERS WITH OP BEFORE MY CYCLES!!

*sigh*...I feel so dumb. Well, from now on I won't DNF my corners so much!

Gear cube, 2x2x4, The 4x4 (4 layered) pyraminx, helicopter cube (not shape change scrambled)

I'm sure clock has been done? Stefan? Mike?

Siamese cube?

Mirror blocks, lol
Magic, (lol?)

I'll keep thinking on it, too.

 

[qqwref]

I'm not sure I'd count those (unless Magic is scrambled, but it's still pretty easy). Mirror Blocks probably can't be truly BLD solved because you can never avoid getting info about the puzzle position by feeling it.

Who did the Master Pyraminx?

I get that about magic and mirror blocks, I was being sorta funny and sorta serious

Who did the Master Pyraminx?

I've solved the master pyraminx BLD a couple times. I used to keep one in my desk at work and I developed a BLD method and practiced sighted solves during breaks one week. I did the solves at home though, I figured solving BLD at work would probably not make for good job security
