Deploy your site with git

This gist assumes:

you have a local git repo
with an online remote repository (github / bitbucket etc)
and a cloud server (Rackspace cloud / Amazon EC2 etc)
- your (PHP) scripts are served from /var/www/html/
- your webpages are executed by apache
apache's home directory is /var/www/

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.

Twitter

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

Used Guid Reporting

Ever wondered if that that GUID you're about to use has already been consumed?

No.

Well you should. Check the twitter feed - twitter.com/UsedGuid, and start reporting your usage of GUIDs. It's the right thing to do.

Throw away those old paper based systems.
