# Every Programmer Should Know :thinking:
A collection of (mostly) technical things every software developer should know.
:point_up: *These are resources I can recommend to every programmer regardless of their skill level or tech stack*
Highly opinionated :bomb:. Not backed by science.
Comes in no particular order :recycle:
U like it? :star: it and [share ](https://twitter.com/mr_mig_by/status/900735231552098306 ) with a friendly developer!
U don't like it? [Watch the doggo ](https://twitter.com/RespectfulMemes/status/900147758845308930 ) :dog:
*P.S. You [don't need to know ](https://xkcd.com/1050/ ) all of that by heart to be a programmer.
But knowing the stuff will help you become better! :muscle:*
*P.P.S. [Contributions ](CONTRIBUTING.md ) are welcome!*
