Because lots of people I talk to where I live (eastern Canada) don’t seem to realize this: the forcible “transfer” (i.e. deportation) of children is an act of genocide according to international law.

You have to be explicit about which module you’re using at all times, even though 99% of the time only one could apply. When the type class resolution is unique, but complicated, there’s no mental overhead for the Haskell programmer but getting all the right modules is a lot of overhead for the OCaml programmer. It also lets us write functions that are polymorphic under a class constraint. In OCaml you have to explicitly take a module argument to do this. If you want to start composing such functions, it gets tedious extremely fast.

And then even once you’re using a module, you can’t overload a function name. See: + vs +.. Basically modules and type classes solve different problems. You can do some things with modules that you cannot ergonomically do with type classes, for example. create a bit-set representation of sets of integers, and a balanced search tree for sets of other types, and expose that interface uniformly from the same module functor. But Haskell has other ways to achieve that same functionality and more.

OCaml’s type system cannot replicate the things you can do with Haskell’s higher kinded types, type families, or data kinds at all (except for a fraction of Haskell’s GADTs).

Largely reasonable?

Haskell is not good for systems programming which sums up about 60-70% of that post. Laziness is lovely in theory but many industry uses of Haskell use stricthaskell for all or most of their code, so I certainly agree with that part too.

Their largest complaint about using Haskell for small non-systems programs seems to be the mental overhead induced by laziness. But for me, for small programs where performance isn’t a huge concern (think Advent of code or a script for daily life) laziness reduces my mental overhead. I think that author is just especially concerned about having a deep understanding of their programs’ performance because of their systems background. I worry about performance when it becomes relevant. Debugging Haskell performance issues is certainly harder than strict languages but still totally doable.

The lack of type classes or other form of ergonomic overloading in OCaml is easily the single “feature” most responsible for the language never taking off.

As a Haskell programmer, “OCaml has the nicest type features” hurts just a little bit.

I sometimes teach a course in OCaml. The students who are very engaged inevitably ask me about Haskell, I encourage them to try it, and then they spend the rest of the semester wondering why the course is taught in OCaml. Bizarre how different that is from when colleagues in industry want to try Haskell.

Is Printf.printf not a good generic print function? It’s even variadic!

Yeah, I like subleq.

• compiler is extremely fast, faster even than tinycc
• strongly statically typed: all values are ints. Since it’s all of them, you don’t even need to write it!
• memory safe: the entire (virtual) address space is guaranteed to be accessible at all times so there’s no way to leak any of it (can’t release it anyway) or to segfault (it’s all accessible).

Subleq is the obvious winner in my mind.

There is no official definition, in part because there isn’t any formal way to define the term that satisfies our intuition.

Most treatments will handle “transpiling” as a special case of “compiling” and some will even handle decompilation as a special case where the object language is higher level than the source. Of course, even defining “higher level” can be quite hard.

Plenty of languages “compile to C” and I see no issue with saying something “compiles to js,” especially given that js mostly lacks features of purescript rather than the other way around.

“Monadic type” has something like three meanings depending on context, and it’s not clear which one you mean. One of them is common in math, but not so common in programming, so probably not that. But neither “parametric types with a single argument” nor “types that encode a category-theoretic monad” have the property you say, as far as I know.

I imagine you’re probably referring to the latter, since the optional monad exists. That’s very different from returning null. The inhabitants of Integer in Java, for example, are the boxed machine ints and null. The inhabitants of Optional[Integer] (it won’t let me use angle brackets here) are Optional.of(i) for each machine int i, Optional.empty(), and null.

Optional.empty() is not null and should not be called a “Null object.” It’s also not of type Integer, so you’re not even allowed to return it unless the function type explicitly says so. Writing such function types is pretty uncommon to do in java programs but it’s more normal in kotlin. In languages like Haskell, which don’t have null at all, this is idiomatic.

Which, to be fair, is also derived from a word which would be most accurately (with English vowels) pronounced as mah-nuh. Although at this point “manna” is definitively also a word of English whose correct pronunciation is with /æ/.

I’ve only ever seen “one-time” in cryptography to refer to One-Time Pads (OTP). They are literally uncrackable (because every possible plaintext could be encoded by every possible ciphertext) but they achieve that by using a shared private key. The cipher becomes attackable if the key is re-used, hence the “one-time.”

But that key has to be exchanged somehow, and that exchange can be attacked instead. Key exchange algorithms can’t necessarily transfer every possible OTP which means eavesdropping on the exchange would make an OTP attackable. So the best option we know of that doesn’t require secret meetings to share OTPs* really is to use RSA encryption. Once we have efficient quantum-resistant schemes, they’ll be the best option we know.

* and let’s be honest, secret meetings can be eavesdropped on as well.

Bril is the only compiler IL I know of that is specifically designed for education.

R. Kent Dybvig’s compilers course has had approximately 15 “intermediate” representations designed for his course since at least 2004 – a consequence of teaching the course using the nanopass compiler framework for scheme. You could broadly divide these into “representations that are restrictions of scheme,” and “representations that are increasingly-annotated versions of UIL” where UIL is the underlying intermediate representation. As far as I know, UIL was also designed for this course.

How does this compare with GumTree? It’s weird that the page doesn’t even mention existing state-of-the-art tools for this task.

edit: I’ve compared GumTree and difftastic myself while working on a project this past week. Difftastic is harder to use programatically (the JSON format is unstable and leaves something to be desired) but other than that it’s miles and miles better.

Most recently, KeyWe and modded Keep Talking with friends. Solo, still ol’ reliable slay the spire.

I have a plan to teach someone how to play schnapsen and crazyhouse chess tomorrow so that’s exciting.

I find there’s a lot less variety in my monster train runs. Most classes have a distinctly best strategy and the artifacts generally also funnel you towards that strategy. For example, I can’t remember the last time I played an Umbra run that didn’t set up a morsel engine behind a warden or alloyed construct - as far as I’m concerned, those are the same strategy, it doesn’t feel different. The only other build I think is viable is just “play Shadowsiege,” which rarely happens early enough to build for it.

Every class in STS has at least three viable archetypes and almost every run within those archetypes still feels different to me.

I almost exclusively play for A20 heart kills. I play all 4 classes but in a “whichever I feel like today” way. I tried rotating between the characters for a while and really didn’t enjoy playing silent or watcher while in the wrong mood for those classes.

My favorite deck in recent memory was probably a silent discard combo with Grand Finale as the only damage-dealing card in the deck. My favorite archetype in general is probably ice defect. A good all-you-can-eat ironclad run is great too.

I don’t think I agree that STS is especially well balanced - some regular hallway combats do irrationally more damage on average even to players much better than me (for example, floor one jaw worms or any act 3 darklings). In general, the game could be quite a bit harder on A20 and still be fun for players who want a challenge. It’s also weird to me that A1 makes the game easier compared to A0. Between the classes, there is a class which is clearly stronger than the others. However I also don’t think this is a bad thing. Imbalances create more opportunities for new experiences, and for different kinds of players to have different kinds of fun. And that certainly agrees with “infinite replayability.” I’m sure in 5 years’ time I will still be seeing interactions I’ve never seen before.

Second Shadow of the Colossus. The moments where you can just sit and look, coupled with the soundtrack, are some of the best in gaming history. Plus that bit of tension knowing what you’re about to get into…

Not only is tunic beautiful; the experience is amazing. It’s even better if you try to solve the main optional puzzle as you go.

Definitely agree that it’s one of the best.

I’m a computer scientist mainly but with a heavy focus/interest in computer architecture. My plan is to teach at a university at this point - but it seems to me like that would be a good place to create completely open standards technology from.^1Specifically because if the point isn’t to make money, there’s no reason to create walled gardens.

There’s certainly enough interest from people who want to be able to build their own systems. What would actually worry me isn’t the ability to make a new open standard or any of that. It’s that AMD64 is very hard to compete with in this space, because the processors are just faster, and there is so much x86 software that people who build PCs usually want access to.

AMD64’s performance is the result of years and years of optimizations and patenting new hardware techniques, followed by aggressively litigating people trying to compete. ARM performance is catching up but ARM prefers licensing their core IP over making their own systems, making it harder for them to break into the PC space even if they want to.

A new player would be in for a long, long time of unprofitable work just to compete with AMD64 - which most people are still happy with anyway.

^1 some others and I are actually working on some new ISA / open soft processors for it. However it is focused at an educational setting and unlikely to ever be used outside of embedded devices at most.
