Yosemite upgrade notes

From a (mostly) Ruby on Rails developer.

After doing the below everything seems to work (some of it worked before doing anything), including Ruby, Gems, RVM, Homebrew, VirtualBox/Vagrant VMs, Pow, tmux, git, vim.

0. Did a full-disk backup that I can restore from
1. Moved out /usr/local to avoid super slow install, per option 1 in https://jimlindley.com/blog/yosemite-upgrade-homebrew-tips/: sudo mv /usr/local ~/local
2. Upgraded to Yosemite
3. Restored /usr/local, per option 1 in https://jimlindley.com/blog/yosemite-upgrade-homebrew-tips/: sudo mv ~/local /usr

# Note: upper bound is 12:01:59 (you could use second precision to get around this, e.g. "12:01:00")

time = Time.mktime(2014, 10, 14,  12, 1)

allowed_ranges = [
  "11:59".."12:01",
]
formatted_time = time.strftime("%H:%M")
p allowed_ranges.any? { |range| range.cover?(formatted_time) }

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.

  class RouteRecognizer
    attr_reader :paths
    
    # To use this inside your app, call:
    # `RouteRecognizer.new.initial_path_segments`
    # This returns an array, e.g.: ['assets','blog','team','faq','users']

    INITIAL_SEGMENT_REGEX = %r{^\/([^\/\(:]+)}

# This module is a starter Ruby client for your REST API, based on Faraday:
# https://github.com/lostisland/faraday/
#
# It supports HTTP basic authentication, sending and recieving JSON, and simple error reporting.
# I use this as a basis for building API clients in most of my Ruby projects.
#
# Use it like this:
#
#     http = GenericApi.connect('http://localhost:3000/', 'myname', 'secret')

To make fonts look normal in Sublime Text, add to Preferences:

// For the editor
"font_options": [ "gray_antialias" ],
// For the sidebar / other elements
"theme_font_options": [ "gray_antialias" ],
