The O’Reilly German office is sponsoring an open source programming contest, running through August 15, with sponsored prizes (thanks to Zend Technologies, Novell, MySQL, eZ Systems, and various magazines) worth more than 20.000 euros–winners will be announced at EuroOSCON.

If you have a programming tool for a web calendar, mash-up project, and/or CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart), be sure to enter! Contest judges are looking for creative, in-depth programming solutions; note that the the calendar and the CAPTCHA are to be programmed in PHP.

(Also note that the web site list information in German only–if you would like information in English, please contact Barbara Mueller in our German office at barbara@oreilly.de)
