The 2008 Google Summer of Code MySQL Projects are now available. MySQL has 14 listed projects, one of the ~190 different Open Source products listed. Unfortunately there is no summary to see the total number of projects being sponsored across all products.
Media Blob Streaming actually has the luxury of two approved projects, so they have plenty of mentoring work at PrimeBase Technologies.
Raj Kissu Rajandran will be working on BLOB Streaming Support for phpMyAdmin and KishoreKumar Bairi on Streaming Enabled MySQL Driver for PHP. Welcome to world of open source for your respective projects.
