For debugging purposes, there's Debug.Trace, which does IO and subverts the type system to do so. But with Haskell, I tend to do less debugging anyway, and more time getting the types right to with; when there's a function that do

Yes, it does imply that, except since Haskell is lazy, you'll be holding onto a thunk until the IO function is evaluated, so you won't have a list of 10 million messages in memory up until you're printing, and even then, list

So, do you mean like you have some big array, and you want to do something like this? (Below is not a real programming language.) for i in 0 to arr.len() { new_val = f(arr[i]); log("Changing {arr[i]} to {new_val}.\n&quo

No, it doesn't, because in a switch with a loop, at the end of each case (after the break), the instructions have an unconditional jump to the top of the switch again, where it performs the indirect jump. With the code using computed g

It's used in VMs, emulators, and other interpreters for making a dispatch loop with less branching than a standard loop with a switch inside it. https://eli.thegreenplace.net/2012/07/12/computed-goto-for-

Not a lawyer, but I don't think art styles are copyrightable, though maybe they could be in Japan.

No, but they can't say that. You cannot trust them to choose rule of law over each other. They hate liberals that much.

You literally cannot reason with such people. They will pretend to be mad about lies as their people lie more. They'll pretend to be mad about laws procedure as they break laws and procedure. They'll pretend to be mad about inflat

And Kamala Harris was labeled far-left for campaigning on a Trump-lite platform on immigration and the economy that appealed to no one.

Funny, because I remember he was a far-left muslim communist from Africa back then by Republican standards.

Yep, you're right. When I was a kid during the Obama years, I was even proud of our country. Now I realize that it and the conservatives in it are basically no different to Putin and his followers in Russia, and the liberal opposition

At my university, when they taught us C++ (and later C), they told everyone to log into this central server running Linux. They taught everyone to use Emacs and write Makefiles, and then we were supposed to be able to do all our assignments

> Pointers are literally 64bit ints... And converting them to an index is extremely quick if you want to store an offset instead when serialising. I'm not them, but they're saying pointer based structures are just less trivial

From the Haskell snippet, f is just "map read" specialized for lists of Integers, so inlining it would read like this : let list = map read (words contents) The equivalent Python is basically this: list = [int(word) for

Why are seed oils unhealthy, though? I can't find anything that's bad about them in particular. I've only seen people commenting online saying to avoid them.

I remember reading some rant about how Unix sucks because of the shell's filename expansion, because programs can't tell whether you wrote a star or actually just all the files in the directory. If programs could tell the differen

It's not a C89 requirement. C89 requires variables to be declared at the top of a block, not a function. So, you could write things like this: while (...) { int a = 1, b = 2, c = 3; printf("%d\n", a + c - b);

Reference counting very much incurs a runtime cost; it's not just a compile time abstraction, like borrow-checking in Rust.

That seems like a convenient way to not change anything. I guarantee most people would still complain heavily if the price of meat went up because something like a carbon tax were applied to it, even though the effect would be to reduce the

Yeah, there should be more types of bananas. There are already many different kinds of apples, e.g., Granny Smith, Honeycrisp, Golden Delicious, Fuji, etc.; I don't see why only one type of banana has to be sold at a time.

In this case, the C declaration doesn't match the other two. The variable x is a function that returns a pointer to an array of 5 pointers to functions returning char. Indeed, that's what cdecl.org says: declare x as function

People who write C nowadays generally try to write it in the most "boring" and easy-to-read way possible, I think. But C can also be hard to understand if it uses a lot of side-effectful expressions and pointer arithmetic. Just lo
