Wandering Around London

Apologies, once again, for the radio silence. Over the past couple of months there have been some complications in my private life, and a remarkable amount of my attention has been taken up with figuring out where exactly I'm going to be living after my current lease runs out (more on that later, perhaps).

Be that as it may, after almost a year, I did find some time to go wandering around the city I now call home. Whilst I took every opportunity to make a brisk constitutional around Edinburgh, I'd never managed to really do this in London. Part

Now We're Blogging with Photos!

Fair warning: this is going to be a bit of a programming heavy blog post. It's also going to be quite Mac specific.

One of the things I wanted to change about the format of this blog was to make it more visual, specifically with pictures. This first part of this was to add pictures to the front page. There were a couple of options for doing so. I could just scan through an article, look for the first image tag and use this. Alternatively I could add a mechanism which allowed me to choose the image, in a similar

Origin Story, Raspberry Pi, and the ZX Spectrum

One of the fun things about working for Google is that from time to time interesting people come into the office to give talks. We had Richard Dawkins a few weeks ago, who gave an interesting if… uncompromising talk. Yesterday we had one of the founders of the Raspberry Pi foundation. For those of you who aren't aware, the Raspberry Pi is an extremely small (exactly credit card sized) and cheap ($25), yet very capable computing platform. The foundation is the charity formed to produce this hardware.

Why is a charity building computer hardware? Because there is a need for

New (ish) Year, New (ish) Blog

2011 was an interesting year for me. A lot changed. I turned 30. After 10 years of residency I moved away from Edinburgh, a city I love dearly, and took a job in London. With Google. As a result, I no longer work with Autonomous Underwater Vehicles for a living. Instead I build web services. Quite the change, I'm sure you'll agree. In the early months of the year I finally completed the corrections to my PhD, and then in the summer: I graduated. It took 6 years (all together) but I am now Dr. Nick Johnson. I also lost

Simplifying the Landscape

At the end of the last post I wrote about the actual implementation of my Clockwork Aphid project, I said the next step was going to be display simplification. At that point I'd generated a few landscapes which were just starting barely starting to test the limits of my computer, though they were nothing like the size or complexity I had in mind. That said, it was looking at landscapes containing 1579008 polygons and it was obvious that not all of these needed to be put on screen. Moreover, because my landscapes are essentially made up of discrete samples (or
