Hackadayed

Inadvertently made the front page of [Hackaday](http://hackaday.com/) with the [solderless drawdio](http://hackaday.com/2010/11/09/solderless-drawdio-terminally-implemented/).

Which resulted in an order of magnitude more hits than normal before my server fell over with mysqld leaking its guts all over the console. The youtube [video of it in operation](http://www.youtube.com/watch?v=ooOPQ4h2pq0) that is also linked to from Hackaday has now had 1600+ hits!

Image processing #002

# Detecting corners

Let’s use a corner detector as an example. [Corner detection](http://en.wikipedia.org/wiki/Corner_detection) is an important image processing task: corners are good things to track over several frames of an image sequence. Once you’ve tracked them you can infer 3-d positions for them.

Change of plan – from Scilab to Octave

OK, I started out on [Scilab](http://www.scilab.org/), but got frustrated! It’s too different to [Matlab](http://www.mathworks.com/products/matlab/) – which has its flaws, but at least I’m familiar with them. I’m always going to be annoyed by the 1-based indexing of Matlab, but I’ve learned to deal with it.
