Meredith Patterson's OBELisQ

Meri wrote a PostgreSQL extension during her 2005 Summer of Code project: OBELisQ, formerly known as Query by Example. All the code (and credit) is hers, I but watched with excitement as the magic happened.

Nuno Cruces's JauVM

Nuno's Jau Virtual Machine is a JVM written in Java, which applied interesting optimizations to speed up execution faster than existing JVM... while running under one itself. Another cool Summer of Code 2005 project I mentored.
