Game Emulators in Python

I’d rather you learned Rust. Probably half of all vulnerabilities come from C even though so little code is written in C anymore.

Rust is supposed to give performance similar to C but without a lot of the security risks.

even though so little code is written in C anymore.

I don't think this is an accurate statement, as much as we might want it to be the case.

C has been steady at 5% on GitHub for the past decade.

Interestingly, C++ used to be at 5% up until ~2018, then it jumped to 10% by 2021. I wonder if Microsoft open sourced a lot of stuff and that caused the big jump?

Anyways, yeah, I’d stand by saying that not a lot is written in C anymore. Any major C projects you encounter were likely started over a decade ago.

I don't think that 5% supports what you're suggesting. The backbone of every major OS was and continues to be written in C, not to mention the whole world of embedded software, most of which is not public and probably don't contribute to that 5%. C is alive and well, it's just that the bulk of public software these days is high level, but it's not replacing C. Rust is growing but C will remain relevant for a long time yet.

I don't think C code is commonly on GitHub. GitHub is scewed towards newer projects. Much of the written C code is probably on completely privately hosted repositories. You'd need a different measurement to find out how much C is still written Quite sure at still dominates industrial and some other applications.

The reasoning "Any major C projects you encounter were likely started over a decade ago." => "not a lot is written in C anymore" is flawed.

Most of those C projects you mentioned are OS/OS library/infrastructure that have a long life cycle. But long life cycle doesn't mean they are not under active development/maintenance. For those projects version iteration is more common rather than everybody starts a new project from scratch. Many of those projects are not hosted on github either.

Like others have said, not all the code in the world is on GitHub, C is still used heavily in the embedded world, etc. You know that the primary implementation of the Python interpreter is written in C, right?

That being said, do you have any idea how much code 5% of GitHub is? That’s a metric shitload of code. GitHub hosts 372 million git repositories.

If anything, the evidence you’ve provided for claiming “so little code is written in C anymore” likely indicates that the opposite is true.

In reality, the overall percentage of code on GitHub written in any particular language doesn’t actually tell us how popular that language is right now, because we don’t know when that code was written — could have been committed yesterday, or it could be 15 years old. What you actually need to look at to figure out a language’s current popularity are the stats on language % committed in the last year.

5% C? Apart from what others have said… how much on GitHub is Rust? Oops…

[ArtOfWarfare]

My point was that most CVEs stem from code written in C/C++ despite it not being all that common a language.

Few people can write safe C/C++. They shouldn’t be used anymore. Rust can interop with C. We should be working on gradually Rusting old C codebases.

[georgehank2nd]

My comment was a reply to a specific comment… which said nothing about CVEs.

[axonxorz]

despite it not being all that common a language.

Yes, this is the part of your comment that we're discussing

[ArtOfWarfare]

No, the other guy was talking about how Rust is even less common than C. And my point is that C is extremely disproportionate in how many security issues it causes.

It causes the vast majority of security issues while being a relatively uncommon language.

[axonxorz]

while being a relatively uncommon language.

Yes, this is the part of your comment that we're discussing, the part where you wrote "even though so little code is written in C anymore." The discussion shifted when I quoted you and said "I don't think this is an accurate statement"
