BarCamp Chicago wrapped up nicely yesterday with a number of talks. There was a talk about Python (I still don’t get why folks aren’t using Ruby, but that’s just me), an open source hardware project demo, a talk on wikis, a talk on couchdb – very nice indeed.

The open source hardware project is called Arduino and is available prebuilt for a minimal price (about US$30 to US$40) – though you could build it yourself if you like (the diagrams are online and available to all). An accelerometer was attached to the Arduino device (which was attached to the computer via USB) and the outputs printed out on the console.

The wiki talk covered what it took to install a wiki and the speaker’s experience with wikis (and MediaWiki in particular).

The couchdb talk discussed couchdb (which was particularly pertinent, because it runs using Erlang, discussed earlier). Couchdb is a database which is based on documents and uses RDF for everything, and which can be spread out among a set of computers quite easily. Note that it is not relational, and it is not object-oriented either.

And of course, what is BarCamp Chicago without Ron May?
