If this works there should be about 6 thumbnails on this page, showing links bookmarked using Delicious, and tagged with “art”.

Changelog:
14.02.2017: Changed from rss to json and cleaned the code up a bit. Also removed Snapcasa from options.

What’s next:

  1. The first version of this plugin used Snapcasa for creating thumbnails, but I switched to thumbalizr.com to get a higher success rate.
  2. The count param doesn’t seem to do anything when calling the del.icio.us api, it always returns 10 results, so I need to handle that in the code instead. I’ve notified them of the bug.
  3. Testing other screenshotting services or making my own.
  4. Choosing an image from the page metadata when available.

Podcastplayer in flash! Php script to convert RSS to XSPF

Create your own free flash based podcast / mp3 player

I like the flashbased XSPF mp3 player. I had planned to rewrite the actionscript so that it could read rss with enclosures instead, but I liked the possibility to have unique pictures on each track, and I wanted to check out the XSPF format.

So I wrote a PHP script that uses DOMXML and xpath to convert an existing rss to xspf, it even have a search function of sorts.

I’m going to use it on a project I’m working on after a little more tweaking but I wanted to share it with other people who has a podcast and want a quick open source way to present their podcasts on their website.

Copypaste the above code into a new file and save it as rss2xspf.php and upload it to your server to test if you have domxml support. (If you don’t it will say something like Call to undefined function: domxml_open_mem. In that case, tough luck, find a new host.)

Read more about XSPF over at http://www.xspf.org/

And please drop a comment if you use it and like or have problems.

You can also send me an email at morten.skogly _at_ gmail dot com.

There’s a lot of room for improvement, like using the rss image in place of a staticly defined image, or inserting a random image, or doing som web2.0 stuff like snarfing the images from amazon or whatever, please let me know if you make something superclever with it :)

Idea for your site: You can use del.icio.us to make your own mp3 podcast, visit bands you like bookmark the mp3s you like with del.icio.us, go there to get the rss, and your set to go, you have the same music on your site as on your ipod :) (You might have to use feedburner.com as a gobetween to create the enclosures and make it itunes-compatible.)

Updated: 06.04.2008: Unless you really really digg the XSPF player linked up above, I suggest you use the superb Jeroen Media Player instead. It is open source and supports both XSPF and RSS directly. It takes up more space, but it has video support and a very cool javascript api.

Userscripts.org: Amazon Sambok and BIBSYS ISBN Search

Hey, my first Greasemonkey userscript!

Userscripts.org: Amazon Sambok ISBN Search:

This is just a fast remake of the Hight Library Linky script. Its my first script, just wanted to check out how hard it would be to rework. Luckily for me it was super easy. It inserts links to two norwegian bibliographical databases.

Bibsys, containing material from universities and colleges.
And Sambok, containing material from most Public Libraries in Norway.

Pretty useful, at least in theory, since ISBN search is quite limiting. But it will have to do for now.
