Over the coming week, there are a vast number of free software events taking place around the world.
At MiniDebConf Vienna, I'll be giving a talk on Saturday (schedule not finalized yet) about our progress with free Real-Time Communications (RTC) and welcoming 13 new GSoC students (and their mentors) working on this topic under the Debian umbrella.
On Sunday, Iain Learmonth and I will be collaborating on a workshop/demonstration on Software Defined Radio from the perspective of ham radio and the Debian Ham Radio Pure Blend. If you want to be an active participant, an easy way to get involved is to bring an RTL-SDR dongle. It is highly recommended that instead of buying any cheap generic dongle, you buy one with a high quality temperature compensated crystal oscillator (TXCO), such as those promoted by RTL-SDR.com.
DebConf16 is only a couple of months away now, Registration is still open and the team are keenly looking for additional sponsors. Sponsors are a vital part of such a large event, if your employer or any other organization you know benefits from Debian, please encourage them to contribute.
