So, it's exactly one year ago that I started using Twitter. I remember that I was always of the opinion that Twitter is one of the most stupid hypes nowadays and that it's so useless to know when other people have a cup of coffee or go to the toilette. Using Twitter actively for exactly one year now proofed this attitude wrong. I'm providing some stats on my live with Twitter in this article and try to explain my personal value of using Twitter in.

I gave 2 sessions at this years IPC SE: A half-day workshop on XML with PHP, with special focus on XPath. And "WebDAV - the good, the bad and the evil", where I dug into the WebDAV protocol and the pitfalls of implementing a WebDAV server. Find and browse the slides directly online, here.

Last year, Jakob and me had to write an elaboration about XPath. This one should enable the members of our university project group to get into the general XML topic and to use XPath and related technologies during the project. This document is the result of our work and represents a comprehensive tutorial on XPath.XPath is the standard language for addressing parts of XML documents. This document gives a comprehensive introduction into and an overview on XPath. Starting with the XML tree model, different ways of addressing are explained. A dedicated chapter describes the possible addressing axis, their meaning and usage. A rough overview on important XPath functions and how to use functions in XPath in general is given. The last chapter concludes with a practical use case of XPath in XSLT. [Read full post…]
As you will have noticed, when reading this page, I brought my new website online. Although I was quiet satisfied with Serendipity, I decided by May this year, that I wanted to bring up a real website again. Since October 2005 I only maintained my web log and my photo gallery on Flickr, due to missing time and lack of motivation to raise a real website again. Now that changed, with switching to WCV.

So, finally I'm blogging again. I was quite busy with learning for my university exams in the past weeks, which turned out to be a good idea and was honored with best marks for both of them: "Logic based commonsense reasoning" and "Knowledge discovery in databases" (aka datamining). But that part would fit more into a private blog. [Read full post…]
While writing tests for the eZ Components Webdav component I stumbled over an issue with Konqueror 3.5.9. While we have working tests for the PUT request (uploading files) for version 3.5.7, this request type did not work with my recent Konqueror installation. Some debugging and request dumping in Lighttpd later I was quite sure that Konqueror was the issue. [Read full post…]
Since I maintain my own server for web, mail and some other services, I do not use my Gmail account much. I originally created the account just by curiosity for their UI and now use it to log into other Google services and occasionally if I need a different account than one of my main ones. What I like about Gmail is, that it seems to have a quite good spam filter. In the past half year about 10 spams got through to my inbox, while more than 900 were filtered into the spam folder (in the past 30 days, if you believe Gmail). [Read full post…]
I recently migrated my server to a new maschine and a new provider. After supporting Kore today with installing spamdyke on his maschine, too, I seized the chance to update my Spam Filtering with Spamdyke in front of Qmail howto on the wiki. The howto describes how to install the most recent version of spamdyke on a Gentoo system, explains the most important configuration options and gives some practical hints for such setups. You can ask Kore, it only takes about 10 minutes to do so ;) and saves you a huge lot of spam. Comments and addtions are very welcome. [Read full post…]
Yesterday we brought out a new version of the eZ Components full bundle, which candidates to become the next stable release of our enterprise component library on December 17th. [Read full post…]
Yesterday night I returned from the yearly International PHP Conference in Frankfurt. As usual this was an amazing event, because you get the chance to meet all those people in real live that you usually only talk to by mail and chat. I really like the ambiance in Mörfelden (where the Conference actually is, not far from Frankfurt), but as Lars stated, it's a good thing that IPC is only 4 days, since a lot of community members would need to detox from alcohol afterwards, if it was longer. ;) You see, we had some great party nights, again.
