Higan is a cycle-perfect SNES emulator, and it's very single-core CPU-intensive. This is what the FAQ [0] says: Full-speed emulation for the Super Famicom base unit requires an Intel Core 2 Duo (or AMD equivalent), full-speed for game

I like how simple it is. Thanks for sharing. By the way, I found one or two bugs. The empty parentheses alone are treated as undefined: > () undefined And I think any equation using empty parentheses as an expression gets treate

You may be right that the body could adapt and eventually I might have just stopped feeling that way. I just decided to stop after a month because I thought I wasn't really trans and because I didn't want to feel so sad anymore. B

I'll only say this due to anonymity, but: mistakenly thinking I was trans, I once took testosterone blockers and estrogen for about a month (having bought them online probably illegally). After a week, I was on the verge of tears prett

I've just realized that what I'm describing is called a rope data structure: https://en.wikipedia.org/wiki/Rope_(data_structure) So, a difference list is a rope, but encoded with closures instead of explicit

Well, self-correction: not a binary tree in the traditional sense, since only the leaf nodes contain the elements. It's that each of the two tree pointers either points to another subtree, or to the start of a list, but not both.

I thought this was an interesting data structure, which is mainly used by Haskell and Prolog programmers. When you ignore the fact that it's implemented with functions, it seems that a difference list is a binary tree of lists. Appendi

It doesn't look at all like hentai, but the art does seem uncanny and stilted. It seems more like obvious wish-fulfillment romance, or at least the first one does; that one focuses on how some really rich guy that's relatively att

I think a good write-up that shows some practical use cases of monads is a paper called "Monads for functional programming" by Philip Wadler. It assumes you're familiar with the basic syntax of Haskell or its predecessors, th

That's true, and many libraries do this. However, it comes at the cost of an unnecessary heap allocation that wouldn't otherwise be necessary if not for this encapsulation. If you want to do this, but allocate on the stack, you ha

C still has fields in structures; you just have to pass a structure as the argument to a function. As long as you're okay with syntax like "self->field" or "self.field" (given a parameter called "self")

Is an entity component system really functional programming? I had the sense that functional programming was more about writing functions that are pure and referentially transparent, and making data immutable normally, which can make code s

> SML in particular is cute if you use your tiny Prolog to implement the type system. That sounds pretty cool; do you know of an implementation of SML that fits into 10 KB of memory because it uses tiny Prolog?

There's an ant called the bullet ant, so named because its sting feels like getting shot. Its Wikipedia page shows other similar nicknames in Spanish and in Portuguese. So, given that other bugs' stings have already been described

That's fair. I taught myself to program using C, and C's conflation of pointer parameters with arrays, and its declaration syntax, confused me at first. And I also ended up with more unexplained glitches segfaults in the beginning

We also learned some first order logic, enough to write the proofs in formal language, though we didn't learn anything about type systems. You're probably right about the ship having sailed, though. It's probably harder to ge

Yes, I was also confused at first. The closest C function to this one is asprintf, because this function gives you back a new, separate string, which you may or may not decide to print. Just imagine if asprintf simply returned a char* point

I'm confused why it's said to be backwards (in the article and by you). This paragraph shows that with a format string with an int format specifer, and then a string format specifier, the token list shows is exactly that, and the

Finding out about how, in a programming language with dependent types, types can be returned from functions like values, feels about the same way as when I learned functions can be returned as first-class values in functional programming. I
