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;

Usage

sed -E -f solver.sed input where input is a file containing the maze.

For best results, resize your terminal to match the height of the maze. To disable animations, delete the lines containing p.

Maze format

The solver assumes the following:

The maze only contains the characters # \nSE
Every line has the same number of characters
There is only one start (S) and end (E)

Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

This guide has moved to a GitHub repository to enable collaboration and community input via pull-requests.

	# Building V8 for alpine is a real pain. We have to compile from source, because it has to be
	# linked against musl, and we also have to recompile some of the build tools as the official
	# build workflow tends to assume glibc by including vendored tools that link against it.
	#
	# The general strategy is this:
	#
	# 1. Build GN for alpine (this is a build dependency)
	# 2. Use depot_tools to fetch the V8 source and dependencies (needs glibc)
	# 3. Build V8 for alpine
