Topic 1/2: OpenSoundMeter

Speaker: Nick Skarott

Sound is always a subjective matter; what one person thinks sounds amazing another thinks is bad. This is unavoidable. But some level of objectivity can bring consistency. Nick has been looking into the free OpenSoundMeter, a project designed to give a free alternative to packages like SMAART and other audio tools used in live sound to bring not only consistency but visual representation to what is going on audibly in a room.

Speaker: Tom Ryder

He’ll run through the whole sordid story, and talk about how to mitigate attacks on self-hosters by a new generation of threats.

Topic 1/2: My first Linux – Slackware

Speaker: Nick Skarott

We all started with something different, but did I start in the wrong way? Nick takes a trip down memory lane revisiting the distribution he cut his Linux teeth on: Slackware.
