Ruby

• rcov: code coverage for Ruby
• ruby-wmii: Ruby configuration/scripting for the wmii window manager (earlier explanation)
• FastRI: faster, smarter RI docs for Ruby, DRb-enabled
• rcodetools: TDD/BDD++, automagic assertions, 100% accurate completion, doc/code browsing…
• xmpfilter: automagic Test::Unit assertions/RSpec expectations and code annotations: superseded by rcodetools
• call_stack: backtrace data and 1.8.5-safe breakpoint/Binding.of_caller

Snippets

• several implementations of “WeakHash”: a hash whose elements might be reclaimed by the GC
• Changing filename encodings in a tarball, and a small refactoring tale
• a less naïve implementation of instance_exec, which allows you to eval code with a different self while passing arguments to the block
• Persistent URLs: really easy (thank you open-uri, SOAP4R, Ruby)
• Simple meta-magic: Not quite a SuperStruct, maybe a SuperClass? automatic attributes and initialization
• Making concurrency simple, and a multi-threaded downloader in 4 (long) lines, and an actual application: Purging referrer URLs concurrently
• Cheapest rsync replacement (yep, with Ruby)
• a more powerful Kernel#caller
• a reworked Benchmark module that runs the target code as many times as needed for the desired precision and confidence levels
• A small FS in DATA and a pure Ruby compiler (in the classical sense)
• tail -f on your browser: Piping logs and stuff through HTTP

• What is going on in the 1.9 branch?: a summary of the differences between the stable branch and HEAD, including the latest experimental features for Ruby 2.0.
• Ruby support for Vim
• How to cross-compile Ruby extensions for win32: Cross-compiling Ruby extensions for win32: rcovrt
• Annotating your source code: general explanation and latest version of the xmp filter which can be used to generate unit test assertions.
• Turning Hiki into a simple CMS

Techniques

• Shuffling an enumerable object: on sort_by{rand} and its bias
• Hash.new{ } form and how to use it to memoize functions
• Recursive structures:
  • Usage with hashes (writing suitable #hash and #eql methods)
  • Equality tests and structural equivalence
  • Pattern matching over Ruby objects
• Enhancing Module#include
• Yet another way to wrap methods in Ruby

Analysis

• Estimating the lexical complexity of arbitrary code, and its application to find the most complex code in the stdlib.
• On the naming conventions of the Ruby stdlib
• Keeping in mind the dynamic include problem
• CPAN vs. RAA: costs
