It makes sense if they hire middles, not seniors

Following this logic whole human life is a puzzle game.

It’s a good suggestion

I still prefer 7z for compression

7z can be at least decompressed in macOS & FreeBSD out of the box.

On windows tar.bz/gz/xz unpacks to tar and then to actual files. As tar is a separate archive format

7z has way better (ultra) compression

7z uses proprietary rar library to unpack

Integer sqrt can be used for integers with any length, not only for integers fit into f64

Integer sqrt is usually not a library function and it’s very easy to implement, just a few lines of code. Algorithm is well defined on Wikipedia you read a lot. And yes, it doesn’t use FPU at all and it’s quite fast even on i8086.

Algorithm is so plain and simple, it doesn’t require nightly or Rust specifically to implement.

Nice article, I enjoyed it. Why float sqrt has been used? Integer sqrt is way faster and easily supports integers of any lengths

Could you please explain why he should be embarrassed by such post? What would you improve?
