30 March 2007 by Joost de Valk » - 19 Comments

I’m doing some work on a site which has like 4,500 pages indexed with a PHPSESSID in the URL, causing some major duplicate content problems. I got the server admin to disable the PHPSESSID’s by adding the following to the vhost config: I also wanted Google to get a clean URL when it decided to »

MSN launches Dutch Digg clone, but forgets spam prevention

15 February 2007 by Joost de Valk » - 30 Comments

Recently (I honestly don’t know when), MSN launched a Digg clone in the Netherlands, called MSN reporter. You can submit your story, and others can vote for it or against it. The top stories go to the MSN.nl homepage. Now the boys at MSN haven’t really thought this through, as they store what stories you’ve »


Sortable table script updated to v1.5.5

26 January 2007 by Joost de Valk » - 15 Comments

I got an email from Mozilla’s director of product management Sherman Dickman today, that my sortable table script wasn’t sorting numbers above 1 million which have comma’s in them correctly (they do have a lot of Firefox downloads ;) ). The problem was caused by the fact that replace only replaced items once, where they »

They “invented” blogsearch, and did a LOT for the webdevelopment and blogging community. Now Technorati, it turns out, is working on the microformats search I asked for only two articles ago (it was there before that, I just didn’t know about it)… Check it out in Technorati’s Kitchen.

Imagine, you can type in a query like “joost de valk class:vcard” and Google comes up with my contact page, because that has a vcard class in it’s markup, the main class of the hCard microformat. This was suggested today on the uf-discuss mailing list, a mailing list I’ve been lurking on for quite a »

Sortable table v1.5

2 January 2007 by Joost de Valk » - 10 Comments

I’ve just updated my sortable table script to version 1.5, in which it is fixed to work in Safari for Mac OS X 10.4 as well, (I didn’t even know that it wasn’t working in there since it always worked in the nightly). I’m now taking new feature requests for this script, so hit me »


FeedBurner history comparison

1 January 2007 by Joost de Valk » - 2 Comments

When I was working on my FeedBurner history graph tool, I thought it would be cool to be able to display the growth of a blog relative to some other blog as well, so i came up with the idea of “just” plotting a few other lines next to each other, showing how they performed »

FeedBurner down?

18 December 2006 by Joost de Valk » - 1 Comment

As I logged in to my Mint stats this morning, I saw that FeedBurner had registered 0 feedreaders for both yoast.com and www.css3.info. Now I know for a fact that that isn’t true, and indeed, one the support forums it seems that more people have this problem. Update: it seems this problem was solved within »

Update to sortable table script

5 November 2006 by Joost de Valk »

Ok, i’ve fixed one hell of a bug in the table sorting script which must have been in there for at least 2 months, screwing up sorting incredibly, sorry for that. I added in a new feature as well, you can now have dates formatted as 01-Jan-1970, and it will sort these right as well. »
