Talk nights

Format is usually two talks: a primary 1 hour (ish) and, a secondary 30 minutes (ish). Talks start at 19:30, but we have the room from about 18:30 to 23:00.

Speakers Wanted

Typically our programme has a technical talk (~1 hr) and lighter talk (~30 min). Once or twice a year we have a "Lightning Talk" format, with shorter talks up to ~15 minutes, with anyone who wants to speak on the night. The qualifications for speakers are simple, have a subject of interest to fellow technical & InfoSec people. The subject can be on technical or security issues, social interaction with technology, based on the current events, or just something entertaining to our attendees. As a speaker you can be an expert, a student, someone learning a new area, maybe a regular speaker on the conference circuit, but we also love to have new & occasional speakers. Send your talk / activity proposals to talks@dc4420.org You are very welcome to propose running activities other than talks, such as hands-on workshop or an infosec pub quiz, or something else relevant to our techie audience! We also welcome occasional company pitches, to sell or recruit, but to regulate the frequency of these we ask you to buy a round of drinks. Also please discuss with Major Malfunction or Tony beforehand! Previous talks
