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;

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!

Metadata in PDF files can be stored in at least two places:

• the Info Dictionary, a limited set of key/value pairs
• XMP packets, which contain RDF statements expressed as XML

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:
