Vue's is especially nice in that it handles deep and imperative updates. For example: you have an observable foo, and it has an array bar. You can read foo.bar directly instead of needing a wrapper getter function. You can also update

I've been helping test https://gasgame.net/ . It's pretty early in development and somewhat unpolished, but it seems you haven't gotten many replies here. Desktop, multiplayer, no mobile support, top-down tan

Take a look at what they've done. The basic idea is that the video is "on rails", moving forward on its own, but at any point you can pause and move around the objects from the video. Then you can go back to the video and it

I think that's a good shortcut. Converting from axis-angle to quaternions is similar to switching from an angle to a vector (cos angle, sin angle). However I didn't really grok quaternions until looking at geometric algebra, and I

Interesting! I've wondered about that. (Also: hi again! we seem to have so many shared interests over the decades — bbs, usenet, gamedev, c2 wiki, programming languages — that we should meet up someday)

Screeps is fascinating but I never got motivated to play it. :( I use the Stanford pages [1] to link to interesting papers and I use Red Blob Games to explore interactive ways of presenting topics. The most recent update to the Stanford pag

I was amazed by how bright this page could get, on both Macbook and iPhone — https://kidi.ng/wanna-see-a-whiter-white/ — and I want to figure out how to use this superwhite on my interactive tutorials. But as far as I

That's more than most of my blog posts :-) Blogger says I have "20 followers" but some people subscribe via RSS. I would normally get ~50 views and ~0 comments.

It is similar in topic but not written in reaction to. I had written the post almost a year ago and posted it a few days ago.

That's more of an intermediate level; I think https://www.redblobgames.com/maps/terrain-from-noise/ is a simpler place to get started. For concepts ("frequency", "octaves", etc.), see htt

Yes. I used "savings" in the title and first paragraph for SEO reasons. This blog post is from 2006, when google didn't change words into other words without asking, so it was useful to use the variant that people search for

I agree. I've put a lot of work into building these types of visualizations (Red Blob Games) and I've been able to come up with useful visualizations for only some of the problems I work on, and for a small subset of the data stru

Yes, xor can be used as part of this — see the paper[1] and code[2]. The idea is that you're generating a random shuffle of a sequence, but you can do it in a way that doesn't require storing the entire shuffled sequence. You

My life is also in Emacs. I'm using it all the time on the new Macbooks and it's working great for me (gui mode, not terminal mode). There are two major versions of Emacs on Mac. There's the "NextStep" version, whic

I use this approach too but it fails whenever there's any state in the elements. An example is input elements: function update() { let value = document.querySelector("input")?.valueAsNumber; document.querySelect

The migration guide [1] lists breaking changes. If you use many Vue 2 libraries you'll want to wait until they're updated to Vue 3. (I reminds me of the Python situation where if you used lots of Python 2 libraries you'd writ

There are some gotchas when using sprites/images for hexagons. 1. The bounding boxes overlap, so you'll want to make sure that the sprites have transparent corners so that they don't overwrite what's in the next hexagon.
