This is a proof-of-concept of a couple of concurrent data structures written in Ruby.

The implementations are heavily commented for those interested. There are benchmarks (with results) included below. The results are interesting, but, as always, take with a grain of salt.

Data structures

AtomicLinkedQueue is a lock-free queue, built on atomic CAS operations.

  },
  b: 2,
  c: {
    alfa: {

Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

• XCode 4.4 does not install Command Line Tools by default
• X11 isn't available anymore
• The installed version of OpenSSL has some bugs

How to work around

module Memory
  # sizes are guessed, I was too lazy to look
  # them up and then they are also platform
  # dependent
  REF_SIZE = 4 # ?
  OBJ_OVERHEAD = 4 # ?

Most active GitHub users (git.io/top)

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Because of GitHub search limitations, only 1000 first users according to amount of followers are included. If you are not in the list you don't have enough followers. See raw data and source code. Algorithm in pseudocode:
