So Fil-C is competing with Go, C#, typescript and Python. If I’m writing a greenfield project where “bare metal” performance isn’t needed, why would anyone choose Fil-C over a more mature GC language? C is more verbose and more error prone

People are so funny about rust. “Safe rust isn’t expressive enough!” -> then use unsafe rust. “Unsafe rust lets you do anything! Even crazy things!” -> then use safe rust. Or just don’t write crazy code? Does bun actually do anything

Sure; but I bet raw pointers are used very infrequently in the new codebase. The code was ported from zig to rust. I bet a lot of pointers became rust references in the process.

If you’ve got one of the older style Mac chargers, the part which plugs into the wall physically separates from the rest of the charger. You can connect different plugs for all the different countries. There is a plastic seam where the char

If the readme is anything to go by, this doesn't look like it was written by hand. Codex if I were to guess. I wonder the coding agent "improved" the code. The readme hints at the prompt: > It keeps the original system&#x2

Eh, that argument cuts both ways. Lots of the defaults in C++ are bad. Like, most people don’t know how compiling all your code in a single code unit will improve performance. Or how to do it. In rust it’s a single flag in cargo.toml which

If you have a hot loop where it matters, you can put an assert outside the loop which lets llvm remove the bounds checks. Or use unsafe { get_unchecked() } to remove the bounds check entirely.

I said rust is just as fast as C++. Not safe rust. Use unsafe where it’s appropriate, obviously.

by josephg 3mo ago
I don’t know what you’re referring to. Unsafe seems pretty well defined for 99% of use cases. Unsafe blocks allow you to dereference raw pointers and call unsafe functions. Thats about it. Remarkably, even in codebases which need a lot of u

Yep. And array bounds checks have a miniscule performance impact at runtime because they're so friendly to branch prediction.

I disagree. Rich text editors on the web are already a massive hack, because there aren’t any built in input elements which support rich text. There’s just contentEditable and textarea (plain text). There’s no such thing as “doing it proper

Should… Whenever I travel, I bring a CO2 meter with me. It’s amazing how often the air is bad. Often in unexpected places. My meter hit 3100 in an uber once. I didn’t even notice until I got to my hotel room and looked at the data log. It w

FOSS doesn't mean you give up all rights to your work. In this case, the software is AGPL licensed, which imposes huge list of requirements on copies - including attribution and sharing back changes. FOSS != public domain.

by josephg 4mo ago
Thats not what you said. You said "copy the license terms". Copying a license isn't the same as complying with one. Though it looks like in this case they didn't do either.

Yes, I agree. But not all technical writing is README files. For books and long form articles, markdown simply isn't powerful enough. And for stuff like this, nobody cares whether or not the source is readable as plain text.
