HaxoGreen is just around the corner, taking place july 28th to july 31st. This years edition is already the fifth of this small but very cozy and nice hacker camp, and unfortunately there are no tickets left.
More info can be found on the Wiki, also there's @HaxoGreen and #haxogreen on Twitter as well as #haxogreen on IRC on Freenode. If you're an attendee and want to give a talk or hold a workshop there's still time! There are some slots just waiting for you. Contact Orga at hello[_at_]haxogreen.lu and go for it :)
