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

Mar 2010

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.

Excellent, thank you for this script. I do not want to stop people from using the Right Click for legitimate reasons, I just want to make it more difficult for low-down scrapers from taking the Home Page content of my high ranking sites and plastering it all over the web, rendering my unique content as just one in 50, and damaging my rankings :( Very much appreciated
