@pixelpaperyarn I hope it's ok to add to this but project euler is good if you're looking to study math oriented programming, and hackerrank is good for practice/prepping for interviews
@pixelpaperyarn I bet there's at least one out there somewhere I've seen these kinds of things before. Your list is real good though!
@vahnj oh yeah, there's tons of them. i just know what's worked for my own learning style so i think there's always room for one more. :)
@pixelpaperyarn always!!
@vahnj yes! i've got a boatload more resources tbh, but only so many characters to fit it into! this warrants a github gist or something.
