Media training/workshop voor hackers: 11 April 2014

Deze presentatie wordt in het Nederlands gegeven
"Security- en privacyonderwerpen staan steeds vaker op voorpagina's van grote nieuwssites en kranten, ook vormen ze regelmatig de opening van nieuws- en actualiteitenprogramma's. Journalisten zijn daarom altijd op zoek naar experts die de problematiek helder uiteen kunnen zetten.

Veel hackers weten dat het belangrijk is dat deze onderwerpen helder worden uitgelegd, maar vinden het erg spannend om dat zelf te doen. Ken je dat gevoel? In deze workshop bekijken we samen goede en slechte voorbeelden van mediaoptredens, gaan we oefenen voor TV- en radio-interviews en tot slot evalueren we samen onze oefeningen. Hieruit halen we 3 algemene en 3 persoonlijke tips. Hiermee sta je volgende keer met meer rust en zelfvertrouwen journalisten te woord."


"Daphne van der Kroft is gefascineerd door de manier waarop technologische ontwikkelingen onze maatschappij beïnvloeden. Ze volgt de dynamiek van technologie, politiek, media en recht op de voet. Daphne is jurist en gespecia-liseerd in het Informatierecht. Op het moment is ze Public Policy Advisor bij bureau Brandeis, het advocatenkantoor dat de rechtszaak Burgers tegen Plasterk voert. Bij XS4ALL heeft ze even Public Affairs gedaan. Daarvoor was ze communicatiestrateeg bij Bits of Freedom."

Please write down your requests here, don't forget enough details and your name

[REQUESTED] Workshop/Seminar Software-defined networking

I'm not even sure if this is the right place to request such a thing, but he! I can try, right? So what is Software-defined networking all about? I've been reading about this subject for a bit and the subject just doesn't land. It's still too abstract for me. I might have been reading the wrong papers but I prefer to learn interactively. So is there anybody else who wants to learn about Software-defined networking? Let fan out and find someone who is prepared to do a workshop on this subject. Suggestions?


We can organize "something" with one of our partners/sponsors, they are expert in visualization, does that ring a bell?

Abouttheroute: *update* I've talked to one of the european DC guys, and he is willing to give us a talk about Cisco's vission on SDN. He is not a programmer/hacker/nerd, but more an architect, but very good at that.

Any takers?
