All talks should be 45 minutes maximum - we don’t care what it’s about - if you think it’s interesting then let’s hear it? You want to practise a conf talk? Go for it! You want to start a discussion ? Sure. 

Talks are not recorded- they can be technical or not - all that matters is that you care about it and want to share.

One caveat - this is not an open mic for sales pitches, it's an evening for sharing ideas not for meeting sales quotas.
