07:10 pm - Posting from the air!
I'm currently flying somewhere over the black sea, en route to London. Singapore airlines is really cool and have the interweb on board. Rock!

09:20 am - GIMP and colour depth
So I'm playing with a new embedded board, which has a nice 16-bit 640x480 colour LCD. So to make
a nice splash-screen I fired up the GIMP did a nice gradient effect and some text. This looked
really nice on my 32-bit colour display, but once you move to a 16-bit display the gradient is
no longer nice and smooth.
So all I want to do is convert my 24-bit colour RGB image to a 16-bit colour RGB image, and get the
GIMP to do dithering. This is something that should be relatively straight forward. Alas I couldn't
find any way to do, and neither could anyone else in the lab.
I ended up using convert, which worked pretty well:
convert -treedepth 5 -colors 65535 -dither logo24.bmp logo.bmp
But it still amazes me that GIMP can't do this. If anyone knows how to do it please let me know!
Here is the image if you want to give it a try.

In fact this whole shark site is pretty hilarious. Don't even ask why I was googling for sharks.

11:44 am - More GoogleMaps fun.
I've updated my google maps interface again.
There is a new tool "Handy Places" which gets a bunch of different map views from a backend database and gives you easy access to them. Of course I still need allow people to add their own bookmarks here, but that should be doable soon.
Length finder has some rudimentry UI for saving stuff, but this doesn't actually work yet :). Otherwise I still think its the best length finder available for google maps at the moment.
Current Place has been updated to correctly give you an idea of the size of the earth you are currently looking at. The coolest thing is seeing how the map gets distorted as you get closer to the poles.

OK, the google maps hacking continues. The latest incarnation is . This basically provides a much nicer UI and gives access to a couple of other cute tools.

01:23 am - Google Maps Fun
Google maps is fun. Google maps API is even more fun!
Just so many cool things to do. My first Google maps hack lets you draw routes on the map (or sat image) and print out the distance associated with it. I've got some other cool things coming up, but I thought I'd get that one out now.
Oh, it is currently centered on work's new building, but zoomed out to see most of the city.

02:01 pm - Python Generators
Didn't understand the coolness of python generators today. I wanted to generate a list of
files in a directory. Previously I had to write a class and do __iter__ tricks. Now I can
simply do this:
def file_walk(path): for dn, ignore, files in os.walk(path): for fn in files: yield dn + os.sep + fn
