Programmer, graduate student, and gamer. I’m also learning French and love any opportunity to practice :)

I use vim, or spacemacs with evil mode (emacs distribution with sensible shortcuts and vim emulation). Or VSCode with spacemacs emulation.
You will pass your current productivity in less than a month. All of the things you describe are easily done in VSCode with vim emulation (I prefer the full spacemacs emulation but it’s not actually a huge difference). You won’t have to move your hands away from the normal typing spot on your keyboard – no home and end, just 0 and $. No control+arrow keys, just w and b (or e or even more motion options). Highlighting is as easy as v and then motion commands. And there are so many more useful things that vim (and vim emulation) make simple and fast. Orthogonal VSCode features like multi cursors still work.
The appropriate comparison is to hate speech – speech which is never tolerable. The kinds of things I wouldn’t say in this comment. Some racial slurs might qualify, in my opinion, but it would be particular phrases using them and not necessarily the slur itself. The N word is obviously not hate speech when certain people say it, otherwise lots of rap music would be illegal. But there are certainly hate speech phrases that use it that are just as bad as a Nazi salute.
Freedom of speech, like any tolerance, needs to have limits and this is a very reasonable one.
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.
tinycc
int
s. Since it’s all of them, you don’t even need to write it!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.
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.
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.
Invidious does use a YouTube API. FreeTube uses Invidious, so probably same story there. I don’t know about the others.
I recently had a back and forth with one of invidious’s developers. Judge for yourself.
I’ve used it to fix regressions, most recently in a register allocator for a compiler. There’s pretty much no chance I would’ve found that particular bug otherwise; it was caused by an innocuous change (one of those “this shouldn’t matter” things) clashing badly with an incorrect assumption baked into a completely different part of the allocator.
I had seen the same effect from an unrelated bug on a different program. When I added a new test and saw the same effect, I had a “didn’t I fix this already?” moment. When I saw that the previous fix was still there, I checked if an older version of the allocator exhibited the same bug on the new test, and it did not. Bisecting found the offending change relatively quickly and further conventional testing exposed the incorrect assumption.
Learning how to program in any language will make it easier to pick up any other language, because the main burden for a beginner is how to think programmatically. However once you’re enough past that wall, being an expert on one language will mostly only help pick up languages that are similar. So if you knew C++, you could pick up the syntax and probably most of the semantics of the others very quickly, because they are similar in that regard. But you’d still probably struggle to actually program in C, because C is lower level (has way fewer features) than C++.
Technically speaking, C is a subset of C++. But that doesn’t mean being a good C++ programmer automatically makes you a good C programmer.
C# is similar to the other two in syntax as well, but it’s much more like Java than either of them.
If you want to make simpler games, you could start with scratch or stencyl. These tools aren’t really programming languages per se but they let you build programs out of blocks that are much easier to visualize and play around with. There’s some research that suggests they are good entry languages and some research that suggests they aren’t, so ymmv. I’ve used both, but I knew how to program already.
For the record you shouldn’t let “usually made with” drive your decisions. Java is still popular for some games. Slay the spire, a very popular deck building game, was written in Java, which is a decently popular choice if you want to support modding. But C++ and C# are more popular simply because that’s what you use if you’re using engines like unity or unreal.
side note: C, C++, and C# are all different languages.
Are you calling for people’s deaths?
Regardless of how serious their crimes are, calling for people’s deaths is not a great way to be(e) nice.
Most of the unfortunate people who support the current administration are suffering from a lack of funding for education and other systemic issues that are not their fault. If the system were to collapse and be restructured, we should aim to help those people, not punish them.
