That’s it. The last step in my life as a PhD student is now complete. Yesterday I successfully passed my thesis defense at Vienna University of Technology. Which means that the next time you leave a comment on my blog, I would ask you to please start your comment with "Dear Dr. Simon" Alternatively, you […]

This week I got my 50 personal printed copies (thanks to my former employer for […]

Quick update to my earlier post on the Sim-City-like 3D pixel art map of Hong Kong. Turns out there’s more of them, and that they’ve been around for quite a while already: The Map Room has this post on a Shanghai equivalent. Other Chinese cities seem to be available as well (see here), but I […]
