Details
This month we're doing a "show and tell" meetup. We have not organised a single presenter, but instead it'll be an open mic night where anyone can get up and show off what they've been doing. This could simply be about a small script, a new gem, a kick-ass feature, a side project, or something else. As an example I wrote a script over xmas for switching a db from integer IDs to UUIDs which I can show.
Been to one of the "This is what I've been doing" night time presentations at NZ Railscamp? This is basically that. So it will be really really boring if you all turn up and it's just me and my GUIDS. We really don't want Matt to have to fill in the spare time with improvised dance so please bring your laptops (we cater for all projector connections) and your code.
Edit: Just to clarify, there is no minimum time required for showing something, it could simply be a static screen with some code that takes a minute to explain. I'll apply a max of 10 minutes though so as to give everyone opportunity to talk.
