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.

struct foo {
   struct bar {
 int x;

Gfx and glium are Rust libraries that aim to provide a "rusty" abstraction over graphics programming APIs.
Both may look similar, and one of the questions that gets asked frequently on IRC is "what are the differences between gfx and glium?". Here is a comparison table:

# unregister broken GHC packages. Run this a few times to resolve dependency rot in installed packages.
# ghc-pkg-clean -f cabal/dev/packages*.conf also works.
function ghc-pkg-clean() {
  for p in `ghc-pkg check $* 2>&1  | grep problems | awk '{print $6}' | sed -e 's/:$//'`

    echo unregistering $p; ghc-pkg $* unregister $p
  done
}

# remove all installed GHC/cabal packages, leaving ~/.cabal binaries and docs in place.
