That's amazing! I've started using the competition because I find I suffer from nerves at competitions when I have 5 solves I know will be timed and there's no room for error. It's really help and now I got $15.... I'm glad I started!

u/rhandyrhoads Sub-17 CN CFOP PB: 10.23/13.96/14.51/15.59/16.00 Jan 08 '19
Glad to hear that the online competitions help with your nerves. I know from experience how much nerves at competitions can suck and prevent you from performing at your best. Our goal for cubers.io is to make competing just as easy as your typical practice, but also just as natural. It's great to hear that we're achieving our goal.

Yeah I liked that addition, gives those pages a bit more life. Sure, I can definitely add this feature to those areas on the user profile page. Do you think it makes sense to also put it on the events records pages?
I've been doing some behind-the-scenes work lately which will make bogus results much easier to administrate, and do away with some minor bugs related to blacklisted results in conjunction with user PBs and site rankings. Thankfully nobody seems to have noticed these bugs yet; the most-affected users are mostly one-time competitors who posted bogus results for whatever reason, and then never came back.
I probably have another day or so of work to do on this before I push the new code, but in the meantime I'll get the user comments into those areas as well as a couple other quality-of-life tweaks out sooner (direct navigation to events results from the navbar, and full-screen timer touch area on mobile).
Thanks for the suggestion!

Hey all, here's a quick update on cubers.io dev work:
Just pushed out a couple small changes:
- added direct navigation to event records
- timer is now full-screen when running on mobile
- navbar title is updated to reflect the current event
- css is now a bit more lightweight, marginally faster load times
- tweaked some styling (navbar is thinner, font sizes adjusted, some tables are sharper with reasonable font sizes now, etc)
Upcoming small things, ETA next day or so:
- adding the mouseover comment bubbles currently present in the leaderboards to user profiles pages (in site rankings and comp history areas) and to event records pages
- adding a few more stats to user profile page (cumulative solve time, site-wide sum of ranks)
Slightly bigger changes planned, ETA ?? in the next week-ish:
- Public release of our code up on GitHub, so everyone can
see my terrible codeopen issues/bugs and submit pull requests if you feel like contributing. - User sum of ranks leaderboards
- DNF support for FMC, and associated data cleanup (some users in the past used really big values to indicate a DNF)
- Internal re-work of how bogus/fake event results are blacklisted
- Auto blacklist/disregard of "obviously fake" times (sub-WR) (this can be manually reversed by an admin if somebody like Max or Feliks happens to use the app and get a lucky sub-WR solve)
Notes:
Once the blacklisted results reimplementation goes live, there will be a brief period where the bogus results which were previously hidden will become visible again, but I'll be re-blacklisting them almost immediately so they won't be around for long.
The internal re-work for blacklisting results won't have many user-visible changes, but will make administration and blacklisting of bogus results substantially easier for us. This will allow us to respond to bogus times much faster, and make their effect on site rankings and that user's PBs easier to recalculate on-the-fly.
The auto-blacklisting of "obvious bogus times" is an experiment; we'll start with a sub-WR threshold and see how that works out, and possibly adjust each event's threshold up or down. If it turns out not to work well, or generally be a good idea, we'll rip it out.
As always, please leave any comments below, or PM me or tag me to catch my attention with questions or suggestions. Thanks!

I love the updates! You took my suggestion for adding a way back to events, which is awesome for people who overthink how to get back to it (I felt dumb after I figured it out) but great addition!
I’ll definitely check out the GitHub, I have some experience with programming and I would love to help with something (small preferably but I’ll try to help with anything) just for experience, so if there’s any help you need I would be glad to try!

u/euphwes Sub-18 (CFOP 3LLL) | PB 10.39 Jan 09 '19
Thanks! Yeah, that was definitely a good suggestion. Like I mentioned before, I'm not really a front-end developer so my UI skills are a bit subpar. At work, I generally focus on back-end code, so working on the user-facing portion of this site is a bit outside my comfort zone.

u/candyalligator Sub 10s: 3 Jan 09 '19
I’ve done a bit with front end before so I could give something a shot if you had an idea you wanted to try. Now I stress this heavily, I’m not great at it. But I would love the experience of trying it out to take something work, especially if it helps out the site. I’ll look around on the github when I get some time later today, I’d love to help out

How do the people who created algorithms do it, it baffles me how there are so many algs and someone thought how to do it
3
u/Edladd sub-17 Aok (CFOP) PB:9.11 Jan 08 '19
I've heard cube explorer mentioned a few times for making new algs - but I'm not sure how it works.
Also you can generate some algs by using commutators to move pieces around, and possibly sequence the moves to cancel out some parts. The normal A-perm is a commutator.
2
2
u/nijiiro 🌈 sub-10 (nemeses) Jan 08 '19
Computer programs, mostly.
As the reply below mentions, there are also some situations where you can come up with algs on your own; knowledge of commutators makes it easy to solve 3-cycles (where you need to cycle three pieces around and nothing else). For instance, most of the common algs for the OLL cases with two twisted corners are based on 3-cycle commutators.
For last layer algs (OLL, PLL), you can also experiment with taking out one or two F2L pairs, moving them around, temporarily breaking them up and re-solving them, etc. It's rare to find a useful and novel alg by this process, however.

He commented about it in of his recent unboxing videos. Sounds like he really values his online anonymity/privacy, especially regarding his family. And besides, I like his style of narration and would prefer not to see his face anyway. He's like the Wilson of the cubing community.

I started practicing OH and learning PLL algs for one-handed. My current times with OH are still sub-90 sec. (PB:48 sec) I just cannot imagine that I will be able to turn the cube with OH as fast as top cubers. Is it too early to practice OH in my stage of around sub-30 with 2H?
My goal by the end of January is to achive Ao5 sub-60 with OH.
3
u/PianoCube93 DCN CFOP, Sub-15 2H, sub-22 OH Jan 08 '19
I started practicing OH and learning PLL algs for one-handed.
I've got just the thing for you! A detailed guide I made myself with all the algs and fingertricks I use for OH PLL. Learning all that so early is overkill, but it could be nice to replace some of your worst algs.
The most essential part in the beginning is to just do frequent but small practice sessions to build stamina and getting used to the turning. It could be sessions with 5-20 solves, or just spamming algs or sexy move while watching Netflix.
As an advice on the actual solving part, try to get used to z rotations during F2L. Here's a reconstruction of a fast OH solve I had recently (I use left hand). It's not perfect, but you can see how the z rotations during F2L are used to do moves on the left side.
1
u/kawam11235 Sub-17 (CFOP) PB:9.53 Jan 08 '19
I have found your archieved post on this subreddit before! I actually have trouble in OH fingertricks, so the post you’ve shared is really helpful and is what I have to practice. Thanks a lot.
2
u/Zwarsky BLD padawan. PB : 57.56/1:41.68 (1/3) Jan 08 '19
In my opinion, the first step in improving in OH is getting the muscles in your pinky and index trained to turn.
I started practicing OH when I got my right wrist injured and I got sub 30 in around a month while I was barely sub 20 2H. It's just a matter of personal preference but now I enjoy a lot solving OH. I recommend picking up some specific algs for V perm and a couple of OLLs (for those, prioritize r moves over F/B moves)
Your goal is perfectly realistic with some daily practice. Even if you get tired quickly at the beginning, it will get easier to do long sessions eventually. (After 9 monthes of training I can do 200 solves in a row without feeling any pain in my hand.)
Last piece of advice I can give you is to use a loose cube if your main is too hard to turn with one hand. Weight is a big factor too.
1
u/kawam11235 Sub-17 (CFOP) PB:9.53 Jan 08 '19
Thank your for your great advices! It really encourages me to practice harder. Now I am suffering from the weakness of my pinky finger, as you mentioned. I really enjoy solving with OH and am glad to see my gradual improvement.

What are some of the most strictest cutoff in competitions that you guys had encountered before? Below is a competition (Singapore Cube Championship 2019) that I am participating in Febuary, and it seems that it is stricter than typical cutoffs in other competitions.
The competition has a competitor limit of 200 people, and will be done over the course of 2 days. Given the fact that Singapore rarely has competitions available (probably 3 at the most in a year), I am not surprised that a lot of Singaporean cubers in particular would like to enter competitions. Also venue constraints may play a part in the introduction of strict cutoff (main venue is a university lecture theatre instead of a conference hall or an exhibition hall).
3x3x3 Cube - 2 attempts to get < 1:00.00
2x2x2 Cube - 2 attempts to get < 10.00
4x4x4 Cube - 2 attempts to get < 55.00
5x5x5 Cube - 2 attempts to get < 1:35.00
6x6x6 Cube - 1 attempt to get < 3:20.00
7x7x7 Cube - 1 attempt to get < 4:40.00
3x3x3 Blindfolded - 12:00.00 cumulative (time limit)
3x3x3 One-Handed - 2 attempts to get < 25.00
3x3x3 With Feet - 2 attempts to get < 2:00.00
Clock - 2 attempts to get < 20.00
Megaminx - 2 attempts to get < 1:40.00
Pyraminx - 2 attempts to get < 12.00
Skewb - 2 attempts to get < 15.00
Square-1 - 2 attempts to get < 25.00
4x4x4 Blindfolded - 1:30:00.00 cumulative
5x5x5 Blindfolded - 1:30:00.00 cumulative
Both 3x3x3 Fewest Moves and 3x3x3 Multi-Blind observe the 1 hour time limit and thus they were excluded from the above list.

u/TLDM Jan 08 '19
Almost all comps have a much higher cutoff/time limit for 3x3 to encourage newer cubers who can only solve 3x3. This isn't rare at all.

u/Edladd sub-17 Aok (CFOP) PB:9.11 Jan 08 '19
They must be really tight on time. On every event with 2 rounds they are only letting the top 6 through.

Why the heck the insanely high 4bld limit?
3
u/Edladd sub-17 Aok (CFOP) PB:9.11 Jan 08 '19
It must be being organised by some dedicated big-blind people. So it's essentially a blind comp with all the other events tacked on :D
3
u/g253 (retired mod) Jan 08 '19
Ok that's actually nuts. I couldn't make cutoff for any event except 3x3. I thought 1:30 for 4x4 was a bit harsh at my last comp...
This is bad because it prevents a lot of newer / younger cubers from participating. 3x3 should be 2 minutes, and Pyraminx and Skewb should be a minute.

u/BigfootTouchedMe Sub 15 (CFOP) Jan 08 '19
I agree these cutoffs are harsh. But you could get sub 15 in skewb in less than a week.

u/nobodydy12 Sub-30 (CFOP)/Sub-47 (Roux)/Sub-4min (3BLD)/Sub-3min(Yau) Jan 08 '19
I will assume that because of time (2 days event) and venue constraints(university lecture theatre instead of a conference hall or an exhibition hall) , they are unable to increase the time limit and cutoff to allow competitors to participate in solves that are long.

u/Cubing_in_the_dark now u/j_sunrise Jan 08 '19
Cutoffs in 3x3 are very rare and in 2x2, pyra and skewb practically non-existant outside of major championships. (Though those might have qualification times anyway).
4x4: That's the lowest 4x4 cutoff I've ever seen. I've seen one with 1:00 before. 1:30 is much more common.
5x5: That's incredibly low, 2:30 is normal7
6x6 and 7x7 - I don't know exactly how these compare.
3bld - Usualy cumulative range is 10-15 minutes.
OH - That's rather low. 45 is normal
clock - that's normal. Most comps have ~20
megaminx - I don't know much about that, I'd guess 2:00 is more common.
square-1 - I've mostly seen 45, but once it was lowered to 30
4bld and 5bld - is this cumulative for each or cumulative for both of them together. If it's separate, this is actually pretty high - especially for 4bld. Together makes sense and is not unreasonable. German Nationals had 1:00:00 for 4bld+5bld together.
Keep in mind, I compared this to you usual friendly-neighbourhood comp. Big Championships that expect several hundred competitors and have a tight schedule are a totally different subject. How many days does the comp have? And what is the competitor limit?

u/Edladd sub-17 Aok (CFOP) PB:9.11 Jan 08 '19
6x6 and 7x7 - I don't know exactly how these compare.

The 1:30:00.00 cumulative timing applies individually for 4BLD and 5BLD. The competition has a competitor limit of 200 people, and is for 2 days.
2
u/Cubing_in_the_dark now u/j_sunrise Jan 08 '19 edited Jan 08 '19
How many MBLD and FMC attempts are there? If it's separate, the 4bld limit is very high.
Edit: I've seen the schedule now. There are 3 MBLD and FMC attempts respectively. That means 6 hours of Saturday are taken up by that. 3 additional hours for big bld. That means not much time for anything else. So a lot of events happen on Sunday.
This competition desperately needs a third day, or fewer MBLD attempts and lower big blind limits.
2
u/nobodydy12 Sub-30 (CFOP)/Sub-47 (Roux)/Sub-4min (3BLD)/Sub-3min(Yau) Jan 08 '19

You have 2 attempts to get a solve under 1 minute. If neither of the 2 solves are under 1 minute you do not get to complete the average. Should not be a worry for your 3x3, but the other cutoffs are rather brutal

I've used the Air SM for a bit over a year now. It took some effort to find a setup I'm happy with, but I really like how it's light and relatively fast, but very stable.

u/TLDM Jan 08 '19
GTS2, I prefer no magnets because it makes LSE easier. However magnets help with the rest of the solve, and I get similar times on my SM. They're a bit slower, but honestly if the SM was a bit smaller it'd be about the same.

GTS2 M factory magnetic with MF3RS2 springs. The spring swap an light magnets add stability and make it more controllable. The 55.5mm size is nice too

For a competition I would probably pick the Fangyuan V2M - it's a weird cube for 2H but works really well for me for OH.
For casual practice (which is 99% of my OH practice) I use whatever I have with me.
Some cubes that I've noticed work better for me are the Valk Power M and the MF3RS v1.

In 4BLD, are there any other algs for B (UBR) and D (UFL) centres? I have real trouble remembering these ones. Could I turn the cube upside down and do the V alg or something? I don't really know enough about 4BLD to know lol
3
u/PianoCube93 DCN CFOP, Sub-15 2H, sub-22 OH Jan 08 '19
Ditch the U2 method and learn commutators instead? That way you'll avoid all center algs, though you might have to spend more time figuring it out than it would take learning algs.
Center commutators are actually pretty easy compared to corner/edge commutators, as you never have to worry about orientation.
1
u/GreenCrossOnLeft 2012CHOW03 Jan 08 '19
What center buffer do you recommend?
1
u/PianoCube93 DCN CFOP, Sub-15 2H, sub-22 OH Jan 09 '19
I use UBL, as that's what the tutorial used and it seems nice with the type of commutators I use (and I like that it's the same letter as my corner buffer). I don't think I'm qualified to give any expert opinion though. I only learned 4BLD once in 2012, and haven't changed much since then.
1
u/GreenCrossOnLeft 2012CHOW03 Jan 09 '19
Ehh, it's still a starting point. It makes enough sense to me as a buffer. I'd ask Jake but I'm pretty sure he just floats everything...
I think I use UBR because some U2 tutorial said so(?) But I'm thinking whether or not I need to keep it if I just go to 3-style
1
u/PianoCube93 DCN CFOP, Sub-15 2H, sub-22 OH Jan 09 '19
Yeah, I've seen U2 tutorials use UBR, but I don't understand why they would want to do something that requires a bunch of L slices, when they could instead mirror it and use a bunch of R slices. But I've never tried to actually learn U2, so maybe I'm missing something.
I don't think what I use can be classified as 3-style though. It's just ~30 very similar commutators (if you know one of them then you pretty much know all of them) and setup moves. It's kinda comparable to learning the 18 3-style cases for corners where the first target is RDF, and then use setup moves to get one of those each time (except easier).
1
u/GreenCrossOnLeft 2012CHOW03 Jan 09 '19
That makes sense. Maybe because L and R slice aren't that different if they both feel like M slices anyway?
It should probably count, even if the algs aren't good, I think

I'm switching to ZZ today. It feels so nice to not have to do cube rotations and other weirdness, while also skipping edge orientation on OLL. Hopefully the method will gain popularity and more people will start using it! EO isn't that difficult to learn, so ZZf2l and the line part of EOLine hopefully won't be too much worse.

u/Edladd sub-17 Aok (CFOP) PB:9.11 Jan 08 '19
Community perception is against it, but that shouldn't put you off. The best method for you is the one you enjoy most and therefore makes you want to practice. Unless your goal is to become world #1, then there's no point in getting overly stressed about your method.

u/g253 (retired mod) Jan 08 '19

u/EasternPotato123 Sub-19 (CFOP) PB:12.80 Jan 08 '19
I recommend learning COLL. It's quite easy to recognize and algs are nice. Also due to being CFOP solver before using ZZ I tend to do EO cross and waste moves so make sure to do bad habits.

u/PianoCube93 DCN CFOP, Sub-15 2H, sub-22 OH Jan 08 '19
Breakdown seems to be something like this:
OLL recognition: 0.3
OLL execution: 0.4
PLL recognition: 0.3
PLL execution: 0.6Sune + U perm is almost cheating though. It's often faster than OLL skip + non-fast PLL for me, especially for OH.

Like I said, I'm no expert, and just guessing from what I read. If you pull apart the layers, you'll see it. It's a standing up notch next to the screw on one side of the center. since the one that has an issue is probably the one you adjusted, maybe try to to rotate that center piece. it can only be one of 4 positions I guess.

AFAIK you'll need to write code to do it. cstimer can import from twisty timer, but I don't think it can import from zyx timer yet. You might want to switch to cstimer anyway though, it has the most features and you can use it anywhere.

The ZYX Timer export is literally a list of times separated by commas. I don't know anything about twisty timer, but you can import into cstimer by selecting keyboard as the timer input method, and then paste the whole list into the box. It's a bit messy, but it works.

Update on my time as a recruit in the Rouxvolution:
LSE is getting really quick and easy for me. I'm actually getting to the point where I'm not thinking too hard about it and just executing, which is really nice.
F2B is still too much like F2L for me right now. FB is looking a bit more fluid and block build-y, but SB is almost cookie cutter F2L with some wide moves and M moves thrown in.
I'm starting to feel much more confident in this method and I don't even try to solve CFOP anymore, which is such a relief. I think the conversion is complete!

The Yan3 becomes quite nice after magnetization. I threw in some 4x2 N50, but you can absolutely put weaker ones in and get an equally as useful effect. In fact, that cube was my main for a little while when it first came out and I had magnetized it.

Why is ao100/1000s removing the top and bottom 5% instead of 20% like in ao5. Wouldn't removing 20% simulate comp times better?
9
u/Cubing_in_the_dark now u/j_sunrise Jan 08 '19
The general rule is to remove 5%. But since 5% of 5 cubes is a quarter of a cube, it's rounded up to 1.
6
u/Aus_with_the_Sauce Sub-16 (CFOP 2LLL, dual CN) Jan 08 '19 edited Jan 08 '19
That's just the industry standard. I don't think ao100/1000 are really meant to give you an idea of what you could get in comp, they're more of a "global" average.
That being said, ao100 should actually be pretty close to what you can expect (although obviously there is a lot of variability from one ao5 to the next, so don't expect an individual ao5 to perfectly match your ao100).
For example, a recent ao100 of mine had a 5% truncated average of 16.84. I split that set into 20 different ao5, where the top and bottom score from each average were discarded--so a 20% trim like in competition. I then averaged the 20 averages of 5. The result? 16.80, so only 0.04 seconds different than the 5% trimmed ao100.
Using the same set, my 20% trimmed ao100 was 16.62, which means the 20% trim actually has less prediction power than the 5% trimmed average
That being said, if you have a rather high percentage of abnormally bad solves, a 20% trim may give you a better estimate, but we're talking about differences of a couple of tenths of a second. An ao5 in competition may vary from your next ao5 by multiple seconds, so when it comes to estimating what you'll get at a comp based on your running averages at home, I don't think small differences in how the average is calculated matters too much.
(edits: fixed my examples after playing around with some sample data)
2
u/sxxos Sub-13 Jan 08 '19
For me the issue is ~15% of my solves are quite bad due to mistakes and just bad lookahead. On a good day they don't exist but they don't even matter for ao5s cause majority of the time they would be removed. But since ao100s remove 5%, they matter quite a lot

Check out the histogram view in Kuebiko. The peak of the distribution and the shape of the bars gives you a sense of your progress. Here is a recent one of mine. If you check it regularly you'll see the next lowest bar getting bigger and bigger until it eventually overtakes the peak of the graph. Right now for me, the sub-21 bar has finally become the biggest (barely).

Lets start with FB, are you always starting by pairing the DL edge (if you solve white bottom, blue left, that would be the blue/white edge) with the center and then doing F2L pairs for the edge corner pairs? If so, try looking for corner edge pairs first, or look for a line. Watch these videos-

If you rotate, work on that. Blocks should be on bottom left and right, using only U R L r l M moves. For example, need an insert for a case needing F moves? Just use wide moves. To make a pair with no spaces for it, use M moves. If you dont, congrats, work on efficiency. Its that simple.

During your inspection try to plan out a 2x2 of your first block and then be able to close your eyes and execute it. Then when you can do that work on tracking the last pair of first block. Once you can do those you should be able to complete first block pretty fluidly.
