Dvorak keyboard, visual proof

The last few years I've been typing in the Dvorak layout, first on regular qwerty keyboards but now mainly on the typematrix 2030 keyboard.

Below you can watch a youtube video about the keyboard (looks a bit cheesy but gets the point across).



First a bit of theory: the basic premise of the Dvorak layout is that the home row (the one your hands rest upon) is more used than the other rows/keys. This makes your fingers travel less distance to the hard to reach keys because most of the time you'll be typing on the home row.
Result: more efficient typing.

One of the criticisms on the Dvorak keyboard is that there is no conclusive proof of its superiority. Now I can tell you it really is better than Qwerty typing, but then you'd have to believe me.

So I present two pieces of evidence:
- someone searched for an efficient keyboard arrangement using a genetic algorithm and found something similar to dvorak.
- the second evidence is my own: I took a picture of my keyboard after a few years of use.


On the left side you can see the picture of my TypeMatrix, which has an extra keyboard 'skin' which prevents dirt and dust to get between the keys.

Pay attention to the shiny bits, which is where the skin is worn from usage. As expected, the home row is heavily used, as is the backspace and enter and the space.

For people suffering from hand/wrist injuries the lessened travel distance is a benefit; for those hunt and peck typists it's also a golden opportunity to learn touch typing. I learned dvorak on a qwerty keyboard with a printout of the dvorak layout in front of me. Peeking at the keys didn't help me at all! In one month I could touch-type and I haven't looked back since.

Given the investments of many people in Qwerty typing, I'm not saying you should switch. If you spend entire days typing, you should at least consider it though.

Timelapse cloud movies

I started this blog as a way to do regular braindumps about hobbies and my main site (cloudwatch.net).

Now, in order to detect clouds at night (which is what the main site is all about) you need a webcam pointed to the sky. It seemed kind of a waste not to use the webcam during the day!
The linux webcam capture software motion was used to gather the images, and then I wrote some scripts on the server to make one timelapse movie every day.

Yes this takes some space, but an average movie of 24h takes about 33Mb of space. I take a picture every 10 secs, so that's 8640 pictures a day. Making a movie with 24 frames per second, you get a resulting movie of 6 minutes.

Alerted by some web post that a rainbow was seen in Ghent at the 26th september 2007, I went back into my archive of movies and looked at it. No luck with the rainbow, but it does show a very eventful day. And it shows how my timelapse cloud movie looks as well :)
