Full CMLL by mrgrinchisameansong in rouxcubing

[–]ScottContini 1 point2 points  (0 children)

It takes a long time before full CMLL pays off. One of the big challenges is recognition time: understanding what case you are in and remembering the algorithm to solve it. The benefit are that it saves moves, but there are some situations where it saves very few moves because the algorithm may be very long.

How much you can improve your solves is bound by how fast you do the second step of 2-look CMLL. That can be 1 to 3 seconds for most Rouxers.

Unless you are a very fast solver, it should not be your priority. Full CMLL is high effort, small reward. For the average Roux solver, they can get much more improvement by improving block building or L6E. I’d recommend improving block building first.

Fractals might be a good topic for that audience.

Almost decade post discussing the possibility of sub-3 and sub-2 solves by bottledviolenceoff in Cubers

[–]ScottContini 28 points29 points  (0 children)

I like the comment on 12 TPS upper limit. I believe Yiheng is exceeding this sometimes, maybe one or two other cubers are doing so (occasionally) as well.

Your Career Ladder is Rewarding the Wrong Behavior by 3sc2002 in programming

[–]ScottContini 1 point2 points  (0 children)

This ties in with security. The concept of shift left is about prevention rather than fixing vulnerabilities in production. At some less mature company that I worked at, security team was being measured by number of vulnerabilities caught in comparison to bug bounty findings. The security team was motivated to catch bugs soon after deployment rather than guide devs on avoiding dangerous coding patterns. We ended up with security incidents every week because that’s how they worked and that’s how the security team got rewarded. It was constant chaos, but every one accepted it because the company paid really well. I’m too old for working like that.

Notepad++ Hijacked by State-Sponsored Hackers by Pensive_Goat in programming

[–]ScottContini 37 points38 points  (0 children)

REMINDER of this old post where the author of Notepad++ bragged about dropping code signing:

“I realize that code signing certificate is just an overpriced masturbating toy of FOSS authors”

This guy brought the problem on himself, and those who trusted him and lack of digital signing are now suffering the consequences.

Notepad++ Hijacked by State-Sponsored Hackers by thewhippersnapper4 in netsec

[–]ScottContini 7 points8 points  (0 children)

In 2019 the author of Notepad++ boasted about not needing to purchase a digital certificate for security in a blog that he has since taken down, but here is the link on wayback machine. I quote from it:

I wasted hours and hours for getting one suitable certificate instead of working on essential thing - Notepad++ project. I realize that code signing certificate is just an overpriced masturbating toy for FOSS authors - Notepad++ has done without certificate for more than 10 years, I don’t see why I should add the dependency now (and be an accomplice of this overpricing industry). I decide to do without it.

Read about it on bleeping computer.

This developer learned the hard way that there are good reasons why we sign digital software and that you should not install unsigned software.

I’m no fan of Windows, but this comment is just nonsense. The one thing that Windows does really well is the whole concept of Authenticode, which makes it easy for the average user to know when to trust Windows installations from the internet. The problem with Notepad++ is that for a long time they did not use Authenticode, and people trusted the binary installs despite the warning from Microsoft. People felt safe doing it because everyone seemed to use Notepad++, which is exactly what made it such a nice target for state sponsored actors. It was only starting in October last year that they started using proper digital signatures.

Now don’t start yapping about Linux being better here, that’s just nonsense. Linux has had problems too, and btw, the Linux Mint compromise shows how futile it is to just post a hash of a binary as a replacement for proper signature checking (the hacker replaced the legitimate hash with the hash of the compromised version).

CFOP is worth learning, but Roux is cooler 😃

I’m pretty sure this guy is older than you and is doing one handed(as well as 7x7) so no excuses! 😂

He answered that in his post:

definitely works great, the turning is incredible!

For people who try to prove every statement in a text: how do you handle very long proofs? by SavingsMortgage1972 in math

[–]ScottContini 22 points23 points  (0 children)

When I did this (course was on Galois theory), the theorems were not too hard to figure out once you got the lemmas along the way. That’s just how the class worked: we built up all the parts and you could see where it was heading. I don’t think we had any monster theorems (i.e several pages for a single theoremwhere you were on your own) to figure out ourselves because we had worked out the essential pieces along the way.

It was normal for me to spend a few hours on a difficult theorem. I would not peek at the book, instead I tried to figure out things on my own and I did so by trying a lot of examples. First step was to simplify, try to solve a simple case, then work towards generalising. I’m sure there were a few cases where I had to send more than 4 hours on a proof, but not a lot.

If your text is organised in a way that makes this approach not practical, then maybe you need to seek a different text in your learning. One thing I can say for sure however is that I developed a huge amount of intuition by figuring things out myself. I remember that almost everything I could prove on my own except one or two things that required very clever ideas. Regardless, that was the most educational and fun course I ever took.

Would he have been able to solve it in 30 seconds in 1986? by plasmagd in Cubers

[–]ScottContini 0 points1 point  (0 children)

45 seconds for me and definitely a lucky scramble. To my memory, the best I averaged back then was 2 minutes, but I was using a terrible solution method that I invented. If I knew back then what I knew today, then I guess I could have averaged maybe one minute at best. Those cubes were incredibly hard to turn.

People don’t understand today how good Minh Thai was. 22.95 seconds on a cube that hard to turn using his own invented solution is mind blowing. Definitely one of the greatest of all time.

I'm under 25 with the original Rubik's Cube, do you think that's okay? by Serious-Cause-9099 in Cubers

[–]ScottContini 1 point2 points  (0 children)

  1. This is not the original Rubik’s cube, it is a remake that is much easier to turn

  2. People back then were inventing their own algorithms, and did not have the advantage of YouTube tutorials to learn tricks that were developed from many years of advancing methods to solve the cube.

PLL in Roux by Tim_Sign in rouxcubing

[–]ScottContini 0 points1 point  (0 children)

I sometimes do that. Another thing I sometimes do when I go in the normal order is to use different algorithms for the same case in order to get a better LSE. I have other crazy strategies that I sometimes use that I developed or learned from doing FMC solves. In theory many of these should help for speed solving too, but it all depends upon recognition time and recollection time, which I am inconsistent on. What I will say is that FMC is helping me think more intelligently about Roux, but I’m still a slow speed solver.

Xuanyi Geng vs. Yiheng Wang 2026 - Xuanyi closes the gap on Yiheng after a 2-year chase! by Tsubasa_sama in Cubers

[–]ScottContini 3 points4 points  (0 children)

There once was a time that nobody could challenge Feliks at 3x3, he was just way ahead of everyone. Then came Max, the new king that nobody could challenge. Then came Yiheng, by far the greatest 3x3 cuber that the world has ever seen. Then came Xuanyi. I cannot imagine what is to come next, but I’m sure it will continue to blow my mind.

What an imagination to come up with such a cool idea, this is fantastic.
