Here you can find some scripts i wrote. You can obtain all scripts (mostly written in php) by sending me an email. The reason why i don't post the source here is because i'd like to know who uses my scripts.

Various

Digital Methods Initiative	I wrote most of the tools for the Digital Methods Initiative (UvA?/HvA). They are mainly related to data retrieval and analysis. Most of them are accessible online
Whatever button	a Firefox extension
Bliki	a wordpress plugin
Wikifier	a wordpress plugin
online transformations	transform one filetype into another. E.g. pdf into html
find forms on a page	This script gives you the html which makes up a form on a page. For easy customized scraper building.
search media links in a page.	this script looks in a page for medialinks such as rm, asx, wmv, mp3, etc. Particularly useful for sites with embedded players. I hate 'em. Just paste the url in the box and click. If the script finds something you'll get the url which you can play in your favorite mediaplayer.
smile	A little script that fetches a fresh smile from Flickr with each page load. It's written as a little joke but it is great to have as the startpage of your browser.

Del.icio.us

The next couple of scripts all use the great online bookmark service called del.icio.us. For more information see this introduction and these posts about del.icio.us on my blog

related delicious tags	enter a url and find how people tagged that particular url
Pheromone trail of delicious tags on delicous' hompage	this script gets all tags of the delicious frontpage and displays them with the frequency used.
