What all developers should know about preventing security issues in their code. The training will cover the material from https://www.mediawiki.org/wiki/Security_for_developers for new or intermediate MediaWiki developers.
Are you still planning to run this session? If so, we need to know how much time you need, roughly how many participants you expect, and any other requirements/requests that you might have.
I would like to!
60-90 minutes would let me cover both aspects. I can split that into two separate talks as well (one for more beginners, one for more experienced mediawiki developers). If it's similar to other hackathons, I would guess ~10 people.
