chef cookbook diff
#!/usr/bin/env python

Usage: cookbookdiff COOKBOOK_NAME COOKBOOK_VER LOCAL_PATH [--nocolor]
Diff your LOCAL_PATH against what is on the chef server for a
given cookbook and version.
--nocolor: don't pipe output through 'colordiff' (in case you want to pipe to something else)
Examples:
cookbookdiff percona_toolkit 0.0.4 ~/chef-repo/cookbooks/percona_toolkit
require "timeout"
module WaitSteps
extend RSpec::Matchers::DSL

Performace patch for ruby-1.9.3-p327

Changes:

  • this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

    ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

  • this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

    This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.

Guide to the Router Facelift

Ember Router Async Facelift

The Ember router is getting number of enhancements that will greatly enhance its power, reliability, predictability, and ability to handle asynchronous loading logic (so many abilities), particularly when used in conjunction with promises, though the API is friendly enough that a deep understanding of promises is not required for the simpler use cases.
