We'll give you 5 minutes to show off your tool, hack, library (did you just write a library to access the Meetup API in Go!?), whatever. We're language and software/hardware agnostic, so it's all fair game.
After you present, it's an open forum. The audience will ask questions and provide feedback. We want to enable as much participation as possible at these meetups, so you'd better be able to take criticism and dish it out (all within reason of course).
The 10th edition of BHNT has been fully booked within hours after it's announcement and the quality of hacks is still improving and astonishing. If you want to participate in our monthly meetup you better act fast the next time - or you ping me to demo sth. and you can still get in.
