The codes really only made to work on my machine (lots of quirks that need to be sorted to set it up) and I'll never put any effort into helping others run it so no point making it open source.
I mean that is pretty much one of the reasons why docker exists.
You're looking at the prime example... although after seeing some other peoples code I may not be as bad as I think
My current task at my job is to add features to an internal webapp, that some guy made before he retired. Indents are done seemingly at random, sometimes there are just 5 new lines in a row, ~50% of the code is commented out, comments are writen in multiple languages and i18n functions are used everywhere despite it not being used (guy probably seen em in examples and thought they are needed).
Thats about 90% of the "coders" out there. As long as you don't do things like that you're gold and overqualified for a job at a FAGMAN (Facebook, Apple, Google, Microsoft, Amazon, Nrtflix) company.
