A collection of useful code snippets in various areas, too small to have their own repository and important enough not to be ignored.
Challenges: a collection of nice programming challenges
ZeroMQ: an easy to use cross-platform message broker
Quoted from zeromq docs:
Programming is science dressed up as art because most of us don’t understand the physics of software and it’s rarely, if ever, taught. The physics of software is not algorithms, data structures, languages and abstractions. These are just tools we make, use, throw away. The real physics of software is the physics of people–specifically, our limitations when it comes to complexity, and our desire to work together to solve large problems in pieces. This is the science of programming: make building blocks that people can understand and use easily, and people will work together to solve the very largest problems.
