I just returned from a week on the Rocio del Mar diving the northern Sea of Cortez (aka the Gulf of California). We dove along the Midriff Islands and had great encounters with Sperm Whales and Whale Sharks, not to mention the often over-exhuberant Sea Lions. Check out the photos.
I’ve just released version 0.0.2 of the Ruby sparql gem. This version is based on earlier work by Pius and Arto and incorporates from SPARQL Grammar and SPARQL Algebra. Further documentation is available here.
