You just write the code, don't stop to think. You only have to implement the very small set of requests that an apt client can make to an apt server. Probably "get package index" and "get package file".

Like za_creature said you can use a language more towards the YOLO end of the spectrum - more Go or Python or JavaScript than assembly or Rust.

Your commit history shows you had an issue of high background CPU use. You probably wouldn't have it in a manually coded implementation.

It means that you use an interpreted language without checked types and have a `test` command that prints out "lol"
