HTML5 Webcam Panorama Viewer

Finally my customer ncm released their HTML5 webcam panorama viewer for Hotel Goldener Berg, which, I’m proud to say, is mostly my work! Check it out with your desktop browser, your smartphone and your tablet. It even degrades gracefully to Internet Explorer 8, though no zooming is possible there.

Reverse Proxy with Mojolicious

During the last month I was working on a project for a customer, who wanted a reverse proxy, so he could modify his web pages before delivery. This posed a very interesting problem which I chose to solve with good old Perl. Why Perl? Because it’s the absolute right thing to use, when you want […]

Java in 15 Tagen

Letzten Monat wurde ich engagiert um die Registrierung für eine neue Webapplikation zu bauen.

SproutCore HelloWorld from master

Facepalm Moments: Android XHR failing

After searching the whole day to fix a problem with a web app on Android devices, I had a real facepalm moment. Just in case, you ever stumble across the problem, that your XHR returns successfully, but empty – check the event, which triggers it! In my case, it was a <a href=“#“> tag, styled […]

Pit Stop / Boxenstopp

12 days ago, my first Palm webOS application went live in Palm’s App Catalog – and I didn’t recognize it… (Thanks, Palm!) It has 1497 downloads already and an average rating of 3.8. (of 5!) It’s called „Pit Stop“, or „Boxenstopp“ in german, and is a very simple app, where you can record the fuel […]
