Prereq:
apt-get install zsh
apt-get install git-core
Getting zsh to work in ubuntu is weird, since sh
does not understand the source
command. So, you do this to install zsh
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
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.

Imagemagick will by default convert a psd to multiple images: | |
convert file.psd file.png | |
will result in file-0.png, file-1.png etc for each layer. If you wanted a single image, use the flatten switch: | |
convert file.psd -flatten file.png | |
Imagemagick is available on osx, windows and linux. And iOS somehow. |

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.
