I assume you're using a screen to type this. Is there something inherently bad about videos on a screen? Or are you just unhappy with the content.

All engineering technology is like this. The core of machine learning is multi-variable calculus and optimization that has been taught to math students since at least the 60s. I bet most EE graduates still couldn't provide a good inter

The assembly example isn't a good comparison. We have compilers that can generate a lot of assembly tricks most programmers wouldn't write. We don't have a way compiler that can analyze the logical constraints of a programmin

A pointer is a valid C++ iterator. > but you trust it to optimize all that garbage away? Yep, if you learn about compilers you learn what kind of optimizations are easy and hard for them to make. The kind that just flattens a few levels

> It could be more performant No, it almost always is. The designers of a generic library can't anticipate the use case, so can't make appropriate tradeoffs. For example, compare `std::unordered_map` to any well written C hash

by commonlisp94 3y ago
That's writing some other language in C syntax. You use arrays or you write a specialized version for the use case.

by commonlisp94 3y ago
It's a nice thought, but in practice C binaries are orders of magnitude smaller than any other language. Also compilers make that tradeoff for inlining all the time.

The operating system you are using is written in C.

I agree with this. Also, how/when did business sneak in here? that's the one that least belongs.

It would make a huge difference if that style were used more in practice. OOP is just functions that are only polymorphic in 1 argument, when you want it on all of them.

You're right, I left out a lot of life situations that could benefit. Let me be a little more specific: - if you're young you probably want to be around others to learn from. - if you're not well established, you want others

> it’s an obvious choice to use coroutines. I agree, but the other choice is to have traditional threads of execution that block. This simple strategy has delivered more successful projects than any other.

Organizations are structured as trees as a strategy to combat N^2 complexity. You talk up, or down. The tradeoff is of course N^2 relationships still exist in reality , so you duplicate effort, and sometimes collide, but it's a good tr

It's actually the other way around. Universities were originally for humanities, and science and engineering got attached. Maybe we just need separate engineering schools.

You just don't understand what's in a language degree. Also do you know a single person who has ever learned to actually speak a language with duolingo?
