This website exists pretty much just to host my blog.
I have varying degrees of activity on several social media sites: Twitter @bobdc, Twitter @learningsparql, LinkedIn, Instagram, SoundCloud, Facebook, TikTok, flickr, SlideShare, and even a bit on MySpace.
Major recent projects:
A jazz album for which I played the upright bass and wrote the songs. Read more at Album "Gin & Heptatonic" by my band The Heptatonic Jazz Quintet.
The O'Reilly book Learning SPARQL, an introduction to the W3C standard query language for RDF.
Tweets from my @learningsparql account are typically retweets of recent SPARQL-related news.
