Four short links: 14 September 2009

NoSQL, Gov 2.0 Videos, Linux Conf, Geodata Grump

1. WTF Is A Supercolumn? -- Cassandra is a NoSQL database, a triplestore that scales superwell. Because it's not the usual relational thing we're accustomed to, the language can be a barrier to learning: ColumnFamily, SuperColumns, and more. This post explains what's what, with examples.

2. Gov 2.0 Summit Videos -- When I grow up, I want to be Clay Shirky, Tom Steinberg, and Carl Malamud. Some videos are up, others coming up soon--stay tuned for Carl's, which received the only standing O of the show. [updated with link to Carl's talk when it was released]
3. linux.conf.au Schedule Posted -- bring the thunda down unda in 2010. The schedule was just released.
4. Transport for London Does Not Like the Ordnance Survey -- an Official Information Request yielded the Transport for London response to an Ordnance Survey "strategy consultation". The OS should appoint an independent body to review their licence documents and pay them based on the number of words deleted. Sound advice too--OS have crippled the geospatial industry in the UK by charging for their (admittedly finely-detailed) data. (via mattb on delicious)
