This week is Irish Hackerspaces Week (the link is for the Dublin events). On Thursday we will have the first ever Lightning Talks night in the space and I hope it will be successful -- I think it would be awesome to have a few short talks every month where members and visitors show off their projects or something cool they've learnt.
This Thursday I'll be giving one of the talks (10 minutes!), on "making your first contribution to open-source." I've had conversations with people who weren't sure where to start, and with this talk I'd be delighted if I can help at least one give it a shot. :)
