/*

  Watch out, os.IsExist(err) != !os.IsNotExist(err)

  They are error checkers, so use them only when err != nil, and you want to handle
  specific errors in a different way!
  
  Their main purpose is to wrap around OS error messages for you, so you don't have to test
  for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
  "file does not exist/directory does not exist"

INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

⚠️ Note!

With VSCode version 1.94, the APC extension broke and there is no fix yet.

So, for those having issues with APC after the VSCode update, I recommend downloading the previous version of VSCode for now (https://code.visualstudio.com/updates/v1_93) and setting updates to manual by adding this to the editor's configuration:

"update.mode": "manual",
