Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

module Rubinius
  class CompiledMethod
    def _dump(depth)
      Marshal.dump([@scope, Rubinius::CompiledFile::Marshal.new.marshal(self)])
    end

    def self._load(string)
      scope, dump = Marshal.load(string)
      cm = Rubinius::CompiledFile::Marshal.new.unmarshal(dump)
      cm.scope = scope

# hopefully a temporary patch so HireFire will run on the Heroku Cedar stack
# NB: the worker type is hard-coded as "worker" below, this must correlate to the type in Procfile
# NB: ENV['APP_NAME'] must be defined (e.g. 'heroku config:add APP_NAME=myherokuappname')

# using ps & ps_scale instead of info & set_workers
