I’ve always been amazed by 3Blue1Brown’s video quality. And then I watched this video:

Turns out he wrote an entire Python library for it all. I just felt like this watching that whole video:

The amount of work displayed here is probably not truly ridiculous, but it’s definitely beyond what I understand. To write a library capable of all that is incredible.

That API?

(Note: I used the mousepad to zoom in, which messed up the formatting. It doesn't look like this normally.)

I need to review how to reblog posts via the Tumblr API...

This is the tutorial that I followed! Note that the end result is not the same as the thumbnail. Also note that this is part 3, the final part of a series, but that there's also a prequel series for getting used to SFML. I would just check out the entire channel, he doesn't have that many videos.

Even the simplest of tasks in coding are Herculean if you’re using anything but Python.

Just kidding. Sometimes it’s Herculean in Python, too.

Why does Youtube keep recommending these insanely impressive projects. First it's the Manim library, then it's some marbles thing, then it's this. I've seen plenty of cool "Lego Technic" engineering on the Brick Experiments Channel and Brick Technology, but this one...man. Synchronized robot movement without collisions is wild to me, though it's probably no harder than some of the other things I've seen.

I'd be hard-pressed to even understand a quarter of the code that went into this.

Looking at some incomprehensible code from a physics simulation Youtube channel. Now, the source code is actually very neatly organized and the variable names make sense, it's just that there are a lot of them. So it's very comprehensible, I'm just barely code literate.

It's only about 1000 lines in total, which is actually a lot, but if I ever tried writing something that did half of what this did, it'd be like 5000 lines.

This is the most popular video on the channel. It's not the one I was looking at the source code for, I think? Unclear to me because I don't even know what kind of sim I'm looking at.

This whole thing was a fascinating read. I've read it before, but I looked at it again today.

Long story short, "branch prediction" is where, if a program needs to have an answer to a logic question before proceeding, it just proceeds anyway, hoping it got the right answer. It checks, and if it was wrong, it backtracks and makes the right decision. But if it was right, then it saved a bunch of time.

And if an array is sorted, then it's going to guess right a ton of the time.

Does anyone remember that theory that a Super Mario 64 speedrun clipping instance may have been caused by a cosmic ray? It's not necessarily true but I and a lot of other people find it a very entertaining idea.

(The theory's mentioned in the description)

For videos on why cosmic rays can cause bit flips, check...this one out? It's been a while since I've seen it.

I assume you can't do much if any data recovery on it? My condolences. That sounds really upsetting.

I might be the only person who does this but DO NOT keep data only on a flashdrive. I have (had) flashdrive that I used for storage for old art and video game saves to make more room in my laptop and it all got corrupted D:

Just finished this short code tutorial series, it was good.

I use the tag “runnerpost” on personal lore, but all my similar tags are much less important. For example:

“[noun] runnerpost” — some subject that I am interested in. Could be fandom, coding, running, etc.

“runnerpost sidestory” — post about my tumblr page lore, or (more commonly) when I have phrased a post specifically so it can do numbers. I don’t think I’ve ever done numbers with this tag.

In reference to the previous post.

So about half a year ago, I followed this tutorial and decided to create objects that can move *and* have mass. So I could see how that affects orbits. Also, added a couple janky zoom in/out and move camera buttons.

Tried adding two, one with minimal mass, because I still don’t get Lagrange points and why L4 and L5 are the *most* stable when I feel like they’ll just fall to the Earth.

Didn’t really help me understand it but it was cool.

Today, I added “trace the orbit” functionality by just plotting the last 200 locations of an orbiting mass. Still don’t understand Lagrange points.

Oh, and I packaged it into a 30 KB exe file but it only has two orbiting masses and no add/remove or aim-the-mass settings. Orbit simulators are a dime a dozen, even ones far better than this. But I learned a bit more SFML.
