I am saying this as someone who loved C for my entire life, when I was in college I did implement most of the assignments in C when prof said python is okay, but I did in C because I loved it and I thought I would learn more by doing them in C. So no hard feeling involved. There is no reputation to defend. You mean security problems everywhere ? do you mean old, broken, nasty build systems ? Do you mean not having si…

Right. The only thing C had going for it was that it was the fastest non-assembly language. I'm biased, I want all C development halted and moved over to Rust. If C is no longer the fastest , for some definition of that, then no one should be defending it at this point. Honestly, I want the LLVM optimized C version specifically so that this last argument for C in any context will be taken off the table. I'm sure ther…

Is there any reason why we can't have a "C clang"? Or has just nobody bothered yet?

Circa 2011 the maintainer of the benchmark game decided to mostly only allow one implementation of each language[0] following pypy developers trying to get program alternatives which weren't pypy-pessimal. [0] some languages get a bye for some reason e.g. MRI and JRuby, but no pypy, and which implementation is blessed is also arbitrary e.g. javascript is v8 but lua is lua.

  impl Hasher for NaiveHasher {
      fn finish(&self) -> u64 {
          self.0
      }
      fn write(&mut self, _: &[u8]) {
          unimplemented!()
      }
      fn write_u64(&mut self, i: u64) {
          self.0 = i ^ i >> 7;
      }
  }

Is there something fishy going on with the NaiveHashMap here? What's happening? impl Hasher for NaiveHasher { fn finish(&self) -> u64 { self.0 } fn write(&mut self, _: &[u8]) { unimplemented!() } fn write_u64(&mut self, i: u64) { self.0 = i ^ i >> 7; } }
