That's true, but unrelated to the common usage of the word "expressiveness" when talking about programming languages. There's often a tradeoff between expressiveness and the thing you're talking about, which I'

And you can use this algebra to refactor data types! It's a surprisingly deep topic. I wrote a blog post about it: https://justinpombrio.net/2021/03/11/algebra-and-data-types.... And someone else wrote a

I wasn't saying that you could get within 1% of the true median, I was saying you could find an element in the 49th to 51st percentile. In your example, the 49th percentile would be -90 and the 51st percentile would be 90, so the guara

Did you actually need to find the true median of billions of values? Or would finding a value between 49.9% and 50.1% suffice? Because the latter is much easier: sample 10,000 elements uniformly at random and take their median. (I made the

On the contrary, I've heard that entropy is a useful lens through which to understand the biological processes behind life. We're used to thinking of living things as processing energy: ingesting high energy food, distributing i

More precisely: you can emulate quantum mechanics using a classical computer, but the best known algorithms to do so take exponential running time.

paredit is what I think of as a half-structural editor. It gives you some structural shortcuts, but the cursor is still on a character instead of on a node, IIRC. My bet (that I've spent a lot of time building an editor for) is that th

I complain about parentheses, and yet I'm building a structure editor[1]. Two complaints about parentheses: - Parentheses obscure the structure of the language. When different syntax is used for different parts of the language, it&#x

Eactly, Eagan is "math-fi", and Borges is "philosophy-fi". And yeah, what Eagan does is absolutely mind blowing. He mathematically derives entire universes entirely unlike our own, determines what it would be like to liv

Well the virtual pet story had two problems! The first is that it seemed to go on forever, and the second was that it ended before the story was complete.

Another game in this vein of "teaching math/physics through gameplay" is Hyperbolica, where you explore a 3D world with hyperbolic (and later spherical) geometry. It's mind bending. https://store.steampowered.

Oh yeah, arena allocation is great. I've used it a few times and it's always a huge performance improvement. The requirements are that (i) the objects you're allocating all have the same type, and (ii) they all have the same

You phrase this as a disagreement, but in my mind this is complementary. The point of the post is that you should define things in terms of what you care about, and then prove stuff about it. The sum: Sum from n=0 to infinity of (-1

To be clear about the history: Make is from 1976, and Autotools is from 1991. Had me a chuckle about these being called modern, they're (some of?) the earliest build systems. https://en.wikipedia.org/wiki/Make_(sof

Isn't the lesson only that ids shouldn't be floats ? If they were integers everything would be fine, but JS numbers aren't integers, even if they look like them sometimes.
