ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

	Very simple HTTP server in python (Updated for Python 3.7)

	Usage:

	./dummy-web-server.py -l localhost -p 8000

	PayPal blocks copy/paste actions in their "change password" form,
	citing some irrelevant security issues as the reason. That's a
	load of crap, and they know it -- disabling copy/paste makes it a
	lot harder to use a decent password generator and a lot easier to
	screw up your pwd when retyping, especially if it's a long one
	(as it should be!).

	So, here's the quick'n'dirty way to use an externally generated
	password in your PayPal account:
