The fake IMAX at Lincoln Square in Bellevue


Thought you saw star wars in an IMAX? They cheated you.


IMAX are ruining their brand and deceiving their advocates. For those that want to know, here is a map of known "real/fake" IMAX screens, based on screen size and aspect ratio.
A green marker indicates a "real" IMAX screen, meaning a screen that is totally immersive and fills your field of vision. A red exclamation mark indicates a "fake" IMAX screen, meaning a screen that is branded "IMAX" the same as giant screens, but is not that much larger than regular movie screens, and does not fill your field of vision. OMNIMAX or "domed" screens are indicated by a purple orb shape.

How we lost our bike virginity


When I was in Boston two summers ago, I had attempted to get a bike to commute to work. I was overwhelmed by the options available. Craigslist was full of people selling bikes – some had 10 year old bikes for $300, while some had 3 year old bikes for $250, some were giving away road bikes, some giving away mountain bikes, some had cruisers, while others had comfort bikes. WalMart had bikes from $75 to $275, while other stores started at $350 and went up to $2000. I was so confused by the options available and the different prices that I ended up whiling away the whole summer figuring out what I want.

image[34] Jen and I moved to Seattle and decided with a stronger resolve to become bike people this summer. Though we had had bikes before, mainly as kids, we both really didn’t know much about what are the different kinds of bikes and which ones are good for what. We were determined, however, and finally ended up with a very well informed choice which we are very happy about. Read on if you are bike virgins like we were and are trying to navigate around the sea of options to get a bike and make use of the awesome summer ahead of us. Also, this post will be most relevant to you if your main use is going to be around daily/frequent commuting 5-15 miles, paved trails in parks, or a little off-roading and dirt trails.

Getting started

We started out by doing a lot of research online. It quickly emerged that there were mainly 3 kinds of bikes: road bikes, mountain bikes and hybrid bikes. Road bikes are very thin and light bikes, with large but thin wheels and drop-down handlebars. These bikes are built “tight” to be responsive to every little pebble on the ground or the microscopic motions you make as you shift weights. Mountain bikes are the exact opposite with thick and strong frames, smaller and thicker wheels and straight handlebars – these will often also feature disc brakes and front and/or read suspensions. Hybrid bikes are the catch-all for everything in between. They are not so thin and light, nor are they too thick or heavy. They have not so thin wheels, nor do they have very thick wheels. They may have suspensions, may not have suspensions. This, it emerged, was the category of bike that would work for us. Read on for what happened next …

Long exposure shows Roomba cleaning path


If you have been following my tweets, I am a big Roomba fan. I have been quite fascinated by the way the Roomba seems to get every part of the room, detects corners to spend more time and energy there etc. The user manual that comes with it tries to explain that the seemingly random motion is actually a concerted exercise in discovering, maximizing power use and efficiency. However, it’s easiest to understand if you look at the long-exposure shot taken by signaltheorist.

The above image shows the entire path taken by a Roomba over 30 minutes. I would really like to see how this looks in a bigger room.

Why I love my Saturn Ion: A visual graph of my MPG


We have a 2004 Saturn Ion. Check out the awesome MPG we get on it:


This is real data. From actual data points my wife and I have painstakingly recorded each time we fill up. The spikes in the chart above correspond to road-trips. You can tell by the nature of the spikes that we have not taken more than one-tank road trips lately 🙁

Predictably, there is a lower MPG in the winter months where you have more stops and slow-downs.

Corresponding to the above, this is how much we have been using our car:
