Connect to the Foursquare API via OAuth, Python

Apr 2010

Everyone's talking about Foursquare, and everyone at my office is flipping obsessed. I chose to participate in the nerdiest way possible I guess. The following post will break down (and even explain, kinda) a connection to Foursquare's API using OAuth (and Python).

Updating a LinkedIn Status with a PUT request (using LinkedIn Profile API, Django, Python)

Mar 2010

As part of a recent project, we were asked to set up a system that allowed folks to authenticate using their LinkedIn credentials. We used LinkedIn's Oauth Authentication API, and plugged it into Django's built-in user admin using django-socialauth. I'm writing this short guide because the Internet seems woefully disorganized & underinformed on this topic.

Prevent content copying nicely with a friendly 'no copy' script

Jan 2010

It's miserable. There isn't any way to slice it. Hobbling browsers to keep people from copying your precious content is lame. During my tenure at GateHouse Media (newspaper company), I was asked to create & implement a script that would stop people from copying the content from our articles. "It's ludicrous", I said.

Hi, first of all.. thanks for giving an alternative to the default settings... And I have a question hoping that somebody can help me. I have the slider working on pages that are by themselves, but I want to load them in what would be a "master" page through AJAX. Thing is that the slider stops working with it's coda-navigation when doing so... I've tried injecting the coda-slider.js through a function with livequery, and I know that it gets applied because if I set the dynamic arrows to false, they appear and the slider works... but I really need the nav to do the working for I want to use some thumbnails. Well, thx again
