Niall Ross has announced a one day extension for submissions to the StS 2008 Coding Contest:
When I announced this contest, I set the submission time for Friday May 30th. However Saturday would be easier for some people. So I've agreed to extend the submission time. Official submission time now closes on Saturday June 1st at 18:00 UK time.
Make sure you register for the conference, too - it's coming up quick!
