Last Monday I had a meeting early evening in Amsterdam and took the train. I walked out of the central station right during the ‘golden hour‘ and snapped this image. I probably should have cleaned the phone’s lens beforehand 😀

..is supposedly taking place next Monday in Den Bosch. This may come as a surprise for those, like myself and BarCamp co-originators Chris and Andy, who remember visiting the second ever BarCamp globally 16 years ago, in Amsterdam on 20 and 21 October 2005. Or those who attended any of the Dutch BarCamps thereafter documented on BarCamp.org (albeit sparsely, I admit). Mediamatic kindly provided the venue in PostCS for that first Dutch BarCamp.

I heard E guffaw as she read that LinkedIn posting and after hearing why, couldn’t resist kindly pointing out their mistake and linking to the relevant BarCamp.org page for that first BarCampAmsterdam of 16 years ago.

De Gemeente Amsterdam wil een meldingsplicht voor sensoren in de publieke ruimte. Iedere organisatie die sensoren in de buitenruimte plaatst zou vanaf het najaar moeten melden waar die sensoren staan. Dit is nuttig om meerdere redenen. Allereerst omwille van transparantie en om de discussie over nut en noodzaak van al die sensoren om ons heen diepgaand te kunnen voeren. Of om te zien welke gegevens die nu door private organisaties worden verzameld, eventueel ook voor een gedeeld publiek belang kunnen worden gebruikt.

Amsterdam gaf eerder al een voorbeeld dat navolging verdient met de start van een algoritme-register, en dit sensorenregister lijkt me een uitstekende aanvulling.

Had fun facilitating a workshop today exploring ethical data use around the Amsterdam Ajax Arena, for crowd control, safety and security around events as well as embedding the several large scale venues on that location better into their urban surroundings. An interesting mix of various threat models and responses in combination with creating a lively urban center where the quality of living is high for all involved. ‘Digital perimeters’ were at the center of discussion. Within various perimeters ever closer to the venue tighter security profiles might apply, meaning different types of data collection and use.

The workshop took place right in the middle of the case under discussion, the Arena board room itself, with a view of the pitch. We’re facilitating a range of these workshops, focusing on ethical collection and use of location related data. The Arena was one of two cases discussed today. The other case concerned responsible use of mobility tracking data supplied by volunteers.

Liked IndieWeb: it’s about first ownership by Elmine (InFullFlow.net)
A photo (or video for that matter) is a special kind of data. Its file size creates limitations to its distribution, but no matter where it’s uploaded, it is always owned by its creator first. Status updates on any platform are owned by the company first and can only be copied to the creator. That is why I think it’s important to use IndieWeb: if you publish updates on your own site and then POSSE them to the big silos (where your friends still hang out), you own your updates first, just like you own your photos.

This is a good observation. In my mind Flickr for instance isn’t about sharing per se, but I see it as an off-site archive next to my photo archive on my laptop and a NAS at home. That it allows for easy re-use of those images in my own site is an added bonus. Will need to write a bit about my own thoughts from this session too.
