Peanuts. (Wait, that's for EDL, not for launch.)

Eval is a lot like goto in that way. In the vast majority of cases, there's a better way to do things -- but in a very, very small number of scenarios, it's the right tool for the job.

By "mix declarations with code", do you mean the ability to put local variables like `int x;` in locations other than immediately at the start of a function? I don't understand why this is a bad thing.

To be fair, the issue of ergonomics is an artifact of C only. In a language with proper sum types (or as I like to think of them, "better enums"), the pattern would look more like this: match library_function(arg) { Ok

If you need something quick-and-dirty, you can maintain an extra `["length"]` field on your table to cache that information. If you want something more polished, use a proxy table with custom methods/metamethods mediating acc

Oh, that's very cool! I had a similar idea years ago, but I didn't have the technical chops to pursue it at the time, and I ended up losing interest. I think this would actually be even more useful in the kind of architecture I&

For what it’s worth, evidence has come out (explained well by this PBS Space Time episode [1]) that makes the “gravity propagates over more than three spatial dimensions” theory a bit less likely. [1] https://youtu.be/3HYw6v

There's a saying along the lines of, the purpose of a tool is determined by how its users use it. For instance, security dialogs are often useless because users blindly click through. Is this a human problem? Yes, absolutely. Does that

'cbau, if you do make it public, I would humbly suggest making it very difficult for people to send you feedback. It would be awful if something as useful to you as this became something you "have" to maintain and keep up-t

This basic idea has deeply infected how I approach software architecture and design. When someone asks me why I wrote something a particular way, it's usually because I'm trying to keep the imperative/environmental concerns s

To be only a little more precise, every proposition becomes a type of its own. The AND operator forms product types, the OR operator forms sum types, IMPLIES forms a function type... The proof of a theorem turns into an inhabitant of the th

Thanks -- that was a very informative link. It sounds like an awful situation for everyone. I genuinely didn't mean to put down your original comment. I've been badly misunderstood in the past, and have reacted poorly to those rea

That's correct. But the article is making a subtly different comparison, which the parent is responding to. Specifically, with one string-literal argument, f`hi` and f(`hi`) are nearly identical from the perspective of the caller, as l

Sorry, my bad. I just couldn't believe someone could be so dismissive of someone else's experience -- I wasn't sure if I was reading a genuine opinion or a parody. I guess I fell for that myself.

I have no particular stake in the specifics of AMP here, but X being a subset of Y does _not_ mean that X is necessarily no more complex than Y. Adding restrictions on something necessarily gives a subset of the original thing, but abiding

I rather inelegantly attempted to describe this as "a twisty and a pushy" to a friend today, while mimicking the animation with my hands. There is no work-appropriate way to do this. :|

I'm happy to see 3Blue1Brown's most recent video [0] get a mention in this article! He does a great job of explaining quaternions though visual intuition. (I do think simply calling Grant a "math animator" is selling him

It's also used in more musical contexts, as with horns and trumpets -- for instance, "to toot one's own horn". (Animals with large trunks, like elphants and mastodons, would be considered to trumpet.) The fact that a far

I'm going to go out on a limb and guess that you may not be aware of what "!=" means. They are saying that "people who can't think for themselves" -- the original argument -- are not the same as "people wh

The `$.extend` example seems a little overdone -- isn't `Object.assign({}, objA, objB)` a sufficient replacement for most uses?
