Robbed. Camera gone.

with 3 comments

We got robbed in Barcelona the day before yesterday. It happened a little after 23:00 hr on the Passeig de Colom. We could have lost more, but in the end it was just my Canon EOS 60D with the EF-S 18-135mm f/3.5-5.6 IS lens attached to it.

We filed a report at the police station on Carrer Nou de la Rambla with the serial numbers of the devices. We believe we have identified one of the two robbers — the one who had confronted us from the front. I must say that the police were friendly and helpful, and they had people who spoke good English.

But that is not the point of this blog post.

Thanks to my friend, Arjun, we figured out that the EXIF data has the serial number of the camera and the lens embedded in it; and if, like me, you upload your photos to Flickr, you can easily see all the metadata even if you do not have any fancy photography software at hand. This makes me wonder if it is possible for websites like Flickr or Facebook or Imgur to flag uploads originating from a tainted device. Client-side programs could do this too. I guess, this needs some kind of stolen cameras and lenses database, which could be tricky. Does something like this exist?

Anyway, I will leave the details of my stolen camera and lens here to leave a trail in the sands of the Internet.

  • Serial number: 1881125429
  • Internal serial number: WB0778966
  • Lens serial number: 0000124725

Welcome to GUADEC 2013

leave a comment »

GUADEC 2013 is starting in Brno from 1st August (ie. tomorrow). We will be holding a welcome event at Ventana Café today from 16:00 to 21:00 local time. The café is located right across the street from this year’s venue.

We have a couple of more social events lined up during the core conference days – a party at Klub Fléda on the 1st of August, and another one at Starobrno Brewery on the 3rd. There is also going to be a film night on 2nd August at the venue.

The customary football match is on the 5th. Please sign up on the wiki if you want to play.

With GUADEC being all that fun, don’t forget to check out the schedule, and the interviews with Ethan Lee and Cathy Malmrose who are two of the three keynote speakers at GUADEC this year.

Last but not the least, if you are travelling to Brno by train, let me remind you about the reconstruction work that is going on at the main station here.

See you in Brno!

GVfs and the GOA volume monitor

leave a comment »

Sometime ago I had written about how we integrated ownCloud in GNOME for 3.8. One interesting infrastructural enhancement that was part of this feature is the GOA volume monitor in GVfs.

Volume monitors

A volume monitor is a D-Bus session service that uses the org.gtk.Private namespace (eg., org.gtk.Private.MTPVolumeMonitor, org.gtk.Private.UDisks2VolumeMonitor, etc.), has an entry in /usr/share/gvfs/remote-volume-monitors/, and exposes your disk partitions, iOS devices, MTP or PTP devices as volumes. These volumes eventually show up on the GTK+ places sidebar.

Online accounts

We wrote a volume monitor which exposes your online file storage as a volume. It listens to GNOME Online Accounts and when it notices an account that implements the GoaFiles interface it exposes it as a volume.

Giovanni Campagna extended GVfs’ shadow mount machinery to make it transparently pick up the credentials for accessing the cloud storage from GOA without bothering the user.

The future

Currently this only works for ownCloud because the underlying protocol is WebDAV – something that has a corresponding backend in GVfs.

To unlock support for, say, Google Drive or SkyDrive we would first need to implement the protocol as a GVfs backend, and then add the GoaFiles interface to the corresponding GoaObject.
