Refining Ruby (or The Best Study of Ruby 2.0 Refinements Yet)
I've editorialized the title somewhat but this article by Charles Nutter is a great look into the world of 'refinements' in Ruby 2.0, what they're intended for, and all of the challenges they throw up, both for developers and language implementers.
The British Ruby Conference.. Cancelled
It's a pretty long story but the British Ruby Conference, which I was getting rather excited about.. is no more. There's a statement as to why but if you want to join the melee of conversation, try here or here. Luckily other attempts are now afoot - news coming soon.
DHH's Latest Project: Colt Heinemeier Hansson
It's DHH's latest release :-) Congratulations to him and his growing family. And before anyone complains about having a human interest story in the newsletter, have a heart - it's Thanksgiving.

An excellent story and walkthrough about both preparing a talk for RubyConf 2012 and what happened while the speaker was there. More articles like this please.
The Cost of Ruby 1.9.3's GC::Profiler
James Golick presents an examination of the flaws in Ruby 1.9.3's included garbage collector instrumentation in his typically punchy style. Luckily he presents a potential solution too: GC::BasicProfiler.
Is Your Application Running with Ruby - Slow?
Two developers moved a large Ruby webapp between two machines and experienced a 50% drop in performance. Why? Clue: It was something to do with RVM.
A 2012 Mac Setup for Ruby development
We see articles like this quite often but there are a lot of handy links here despite not being particularly Ruby focused.
A Lightweight 'CMS' Using Ruby and Google Drive
An interesting approach to content management. Let users enter text in a Google Drive spreadsheet, grab it with Ruby, and use the data to create your content or templates locally.
A 'yield' Gotcha Every Ruby Developer Should Be Aware of

Convert Syck to Psych YAML Format
Change has been afoot with Ruby's attitude to YAML parsing for a while now but the shift from Syck to Psych can still cause issues. If you still have legacy Syck-produced YAML files around that are causing problems, this code might help.
Daybreak: A Simple Key/Value Store for Ruby
Very lightweight and very Ruby (in the best possible way).
chruby: Changes The Current Ruby
An 'ultra-minimal' (around 80 lines) alternative to RVM and rbenv. chruby allows one to install rubies into /usr/local/$ruby, /opt/$ruby or ~/.rubies/$ruby but install gems into ~/.gem/$ruby/$version. chruby only modifies $PATH, $GEM_HOME and $GEM_PATH, and does not hook cd or rely on shims.

Giles Bowkett: 'I Wrote An eBook In A Week'
Being silly enough to not send me a copy for review or give me a title, all I can do is say Giles has written an interesting sounding book about how 'DHH gets OOP wrong' but why that's OK. It costs money but hopefully we'll see some reviews soon. He does have a no-quibble refund policy, however, and his writing is always an eye opener.
