You should never do this in a source file included with your library,
app, or tests:

    require 'rubygems'

The system I use to manage my $LOAD_PATH is not your library/app/tests

Ruby 2.1.0 in Production: known bugs and patches

Last week, we upgraded the github.com rails app to ruby 2.1.0 in production.
While testing the new build for rollout, we ran into a number of bugs. Most of
these have been fixed on trunk already, but I've documented them below to help
anyone else who might be testing ruby 2.1 in production.

@naruse I think we should backport these patches to the ruby_2_1 branch and
release 2.1.1 sooner rather than later, as some of the bugs are quite critical.
I'm happy to offer any assistance I can to expedite this process.

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.

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

Hi Donald (and Martin),

Thanks for pinging me; it's nice to know Typesafe is keeping tabs on this, and I
appreciate the tone. This is a Yegge-long response, but given that you and
Martin are the two people best-situated to do anything about this, I'd rather
err on the side of giving you too much to think about. I realize I'm being very
critical of something in which you've invested a great deal (both financially
