I hear what people are saying with hackathons and the 'quick and dirty - get stuff done' approach, which isn't what we're aiming for at all.
I'm interested in hearing what people would like to see or think would be interesting to do for a day long event that is programming-language agnostic, i.e. is more akin to our monthly meetups. I'd be interested to hear people's experiences if they've attended any all-day code dojos before and what they through worked well and what could be improved.
On the subject of hack-days: one of the things I'd really like to do is to do a hackathon to produce a simple version of the Kanban game, and exposes an API so that the game can be driven by 'robot' players rather than real players.
i.e. we program players and see what the effect of particular strategies is on throughput - making it a kind of simulation tool rather than just a fun/learn kanban tool. It would (of course) be released under a permissive Open Source license on Github, with everyone's code being visible as contributors.
The down side of this is that it necessitates committing to a particular technology stack, and whilst I'm quite stoked about Meteor (Node.js, CoffeeScript, Mongo, WebSockets, Handlebars templates, LiveHTML, smart packages, push button deployment - http://meteor.com/
) - I'm not sure it would suit everyone and is not so inclusive. I think I'll still do this, in cooperation with the (currently dormant) CoffeeScript user group, but not for the first 'Day of Code'.
Your experiences/feedback on day-long code dojos (as per first paragraph) much appreciated,
