This seems like a good explanation of an alternative implementation of red-black trees to the standard CRLS one. This blog actually has a lot of, in my opinion, interesting posts about data structures and algorithms, and many of those are a

I was expecting some ancient Greek algorithms that used stacks or priority queues, haha.

Why do companies do that? Shouldn't it be enough that you have experience contributing to a large project long-term and you can program decently? Is it that modern programming just requires different/additional programming skills

Likely you know this, and you're just being funny, but the try/catch statement is more like setjmp/longjmp in C. The Result type in Rust is syntactic sugar for integer return codes, returning early on errors, and tagged union

It seems like it would be more practical to create non-zero integer/other number types, and only those can be used as denominators. But it would also be nice to not have to make a custom subtype every time you needed something with a s

You could say the same thing about variables, expressions, statements, and structured programming. It's a lot higher level than assembly language or machine code programming. > Registers, addresses, and machine instructions are rea

Yeah, a lot of people who developed important technologies (TCP/IP: Vinton Cerf and Bob Kahn; Unix: Dennis Ritchie, Ken Thompson) were born in the 1940s. My grandmother is in the same age range, but barely knows how to use a cell phone

They do keep runtime array indexing checks on. I'm pretty sure I remember reading a comment from Steve Klabnik on here that they only turned off overflow checks in release builds by default because array range checks stay on. With neit

Maybe to appeal to C and C++ developers. Rust makes its syntax superficially similar to C/C++ syntax in many other ways: pointer/reference syntax, declaration of "struct" types, generic types using <T>, curly brace

That looks like a pretty cool game! Were you inspired by Crypt of the Necrodancer? That's one of my favorite games. I was thinking about whether an NES (or another older console) would have been able to handle a game with those mechani

Those languages have safe interfaces (the programming languages themselves) over a runtime that has to use unsafe code at some point (e.g. to write the garbage collector). If that's not memory safe, then Rust wouldn't be considere

Dynamic scope means you that whoever last bound the variable at runtime determines its value, not whichever outer scope surrounds it. I guess it would be something like this in pseudo code: var dynamic = 5 function foo() { print(

Thanks for this response as well. I didn't see it earlier. It seems pretty interesting what you can do with C++ templates.

That makes a lot of sense, thanks. I hadn't even thought about that. I guess you could also have MultiplicationExpression have an implicit coercion operator so you can use it in places where a matrix is expected, which would just compu

How can you? Genuinely asking. You can overload operator + or operator *, but how could you make a dedicated ternary (three-way) operator that combines those two operations into something like std::fma? I guess you could overload the functi

Yes, I think you're right. When I eat something that's too spicy for me, I can't taste anything. My tongue is numb and feels like it's burning. It doesn't even have to get to the level of screaming for water; I can

> Presumably any other language that can run on a virtual machine, like WASM, is also to be included! Exciting days ahead :) C can be compiled to WASM, and it's not a memory safe language, so this can't be true...
