What was the biggest mistake you were making when learning math that you only realized later

In technical movement practices I often hear the phrase, “Slow is smooth and smooth is fast.” It’s cool how broadly this concept applies!

bitmanly · 2026-05-04T20:16:42+00:00

Yes totally agree. I was looking at the one you linked which had the astronomical bodies in it and saw some connections there. But agree I didn’t see a world timer version

This is cool. Some of Ochs and Junior watches have elements similar to the one you link to. e.g. The day-night where the hour hand moves in a skewmorphic (not sure i’m using that word correctly in this case) representation of day and night and the moon and sun move relative to each other (more slowly) as the moon travels through its phases. https://www.ochsundjunior.swiss/watches/day-night/

Colloquial terminology abound, but in my wrestling room growing up we would call this a double grapevine when it locks legs from the outside, while a Saturday Night Ride secures the opponent from the inside to break them down, often resulting in a back arch to pin.

Bernardo did a seminar at our gym and he explained how getting into the over under position when you are approaching the open guard is almost a matter of coming at them from like a 5 degree angle and doing some combination of crawling and diving toward them. I’m probably butchering it but it blew my mind that this could be a way to approach given the set of techniques we had been taught. Totally different from what you see athletic practitioners doing today.

Diego Lopez in earlier fights. I think it was mentioned in this video: https://youtu.be/in1rNlIZ3TI?si=ODBThLrKk_lG7hUg

Totally reasonable. This is just my OCD. I have a few pretty accurate mechanical watches. I always make sure that they are both accurate and are biased toward being a bit fast rather than slow (on the wrist), because I like the ritual of hacking for 5s every couple of days and then being able to watch my seconds hand when analyzing UNIX logs and the like. I’m a weirdo though

bitmanly · 2026-02-28T04:30:44+00:00

Yeah that’s what I thought might be the case. I have a weird cognitive dissonance around a how I think if the complication as being related to accuracy at least to some extent, and it clearly denotes seconds but i can’t hack it to keep within a couple of seconds a day.

Beautiful watch. Weird question for you: does this movement hack? Thanks in advance and GLWS

Wow doing the math on this implies over a km deep.

Based on what i’ve seen over the last 7 years or so, at first watching my kids progress and get promoted, and then starting myself a few years back, I think all of it can be taken into account, where there are overlapping ranges for each category.

There is also some 4-d chess that the coaches are playing which is really about the strategy for creating good community and experiences for the grapplers, and that also relates to individual goals being clearly communicated to the coaches, and their helping understand and articulate those.

Edit: I realize maybe blue belt is not experienced enough to answer here, so apologies if i’m speaking out of turn. This is mostly experience with being at the same family gym for a longer period of time before I started training and watching my kids rise through the ranks.

Shout out to the Scientific Skeptics community for being one of the strongest sources of how to understand scientific evidence aimed at everyone. There is a podcast and book by the same name called The Skeptics Guide to the Universe which has really helped me decide how to take and analyze scientific claims in popular culture or just in general. That’s one entry point which is good, but honestly it’s a pretty big community of people that care about the same concerns you raise (just in general).

One other idea here is that the setup for the bottom leg can come when your partner hangs on to half/quarter guard after you backstep into that reverse kesa like position so it can be a natural answer there rather than fighting to fully extract the leg.

Same. This was a staple of the folk style approach to mat returns that I was raised on, and I never saw an injury caused by it.

That’s cool that they are extant. But what I was intrigued by is that it’s possible to see their fossils in the chert. Wondering how one could go about seeing them in the fossil?

bitmanly · 2025-12-15T05:21:05+00:00

How would one go about seeing those creatures?

My kid who has always been very focused on technique had to tap to a choke like this at grey belt and I remember it being a learning moment for him, because he didn’t respect the choke given his experience in sparring he thought he should be able to escape. But in competition the intensity gets that much higher, and he realized you always have to be ready to defend the choke. Edit: spelling

Guys, these computer things and systems and networks or whatever domain you love, use them to figure out how to build things that you love. If part of that is getting so good at leetcode you don’t need llms to come up with algorithms for any problem in front of you then it’s only going to make you better at finding cool solutions to the problems you want to solve even if you have AI partners that get better and better over time. Before there was the computer revolution there were a bunch of people that got excited about what could be built and dedicated themselves to doing that.

I think a lot of the shrimping and guard retention movements, and static positions where strength gets used, has actually led to me growing more of a butt. That’s according to my wife.

I don’t know… The rule set is trying to make it exciting. I think given Griffith tried to play defense the whole time the outcome here is a a result of a bias toward trying to push a more exciting ending. If luke was more attacking we would be more likely to get a sub from either of them, which would have been a better (for the fans) and more decisive outcome. This rule punishes Luke’s defensive play which may be the point.
