Far too many photos from Dagstuhl

A view not often seen

Regular readers here will likely remember various past posts extolling the virtues of Dagstuhl, this really wonderful computing research facility in Germany. I’ve been lucky enough to attend several seminars on the Theory of Evolutionary Algorithms in the past, and have taken (and posted) quite a few photos from those trips.

A few months ago I had the (totally) unexpected pleasure of being contacted by Christian Lindig, a member of Dagstuhl’s scientific staff, and asked if I would be willing to return to Dagstuhl for the specific purpose of taking photographs for them. They’re apparently in the process of re-doing all their brochures and such, and liked what they’d seen on Flickr.

As a result I’ve spent a very pleasant few days back at Dagstuhl in some gorgeous spring weather (I’ve only every been here in the winter before), enjoying the company of a fine group studying the Design and Analysis of Randomized and Approximation Algorithms. (They’ve been very patient with an intruder who always seemed to be waving a camera about, and for this I am grateful.)

I’ve taken something over 1,000 photos, with a few more planned for tomorrow morning before I leave. Some of the participants have asked if the photos will be made available. I have uploaded everything I’ve taken this week to my “events” account on Flickr, all under a Creative Commons license, which means that participants are welcome to download and use any that they wish, as long as they provide attribution. (Note that I am not, and can not, provide any sort of permissions from individuals photographed - that’s their right and prerogative. If you want to use someone here in a beer ad, you need to get their permission first.)

Where are they all?

  • Everything I’ve taken this week is on my “events” account.
  • I also have a Dagstuhl set on my “real” Flickr account that has some of my favorites (with cleaning, cropping, etc.) from my various visits to Dagstuhl. At the moment this set is heavy on shots from previous trips, but I hope to add more from this visit as time allows.
  • Earlier this year I posted everything (without cleaning or editing) from the Jan/Feb seminar on Evolutionary Algorithms to my “events” account.

It’s not yet clear what all Dagstuhl may do with these, but they will contact anyone who is recognizable in a photograph for permission before using your image in any of their materials. If anyone objects to being included in these vast oceans of photos, please let me know and I’d be happy to remove the photo in question.

Thanks again to Christian for inviting me out to Dagstuhl, and to the Randomized and Approximate Algorithms group for being patient “hosts”. Enjoy the photos!

Right in the thick of it

Right in the thick of it

We all arrive at Dagstuhl on Sunday night for the week’s workshop. After a long day of traveling we enjoy some of Dagstuhl’s exceptional food, meet with folks, and catch up.

Above is the conversation during dinner tonight. It’s not the sharpest photo I’ve ever taken, but I think it captures the spirit of the room quite nicely.

And then we (at least quite a few of us) get to work. The photo below was taken at 9:30pm (probably 2.5 hours after the previous one), and there were quite a few people in this lab at the time. And there’s another lab elsewhere in the facility, and the library, and people’s rooms. I’m sure that lots of folks were also hanging out in the coffee room or playing pool, but there were a lot of people working on a Sunday night as well.

It helps if you enjoy your work, and most of these folks are extraordinarily interested in what they’re studying.

Encapsulating knowledge


While I’m at Dagstuhl this year I’m going to try (amidst all the “real” work) to capture something of what the workshop is like and, more generally, what it is to do (computer) science. This is hard because it’s not flashy high-action bull-riding kind of work, but it’s important, significant work and deserves to be documented. I’m just going to have work harder at it.

I’m also probably going to take more people pictures than I would be naturally inclined to. If anyone finds them self in a photo here and objects, let me know and I’d be happy to remove it.
