I haven't got much more of my thesis written in the past few days, and I'm meant to be sending another chunk to my supervisor on Wednesday. Which means I'll need to do a lot tomorrow, somehow. I know the overall structure of what I need to write, it's just a matter of realising enough things to talk about in the right order. I still need to finish off the final bits of programming too. However, over the weekend I fixed my likelihood calculation for P(Q|O) for HMMs, and fixed my simple Markov model to be able to correctly do a more precisely equivalent calculation than before, so it's a good thing I hadn't already tried to write up the relevant sections.
Free software
I've been unwillingly but fairly successfully stopping myself from doing non-work-related coding, and from spending too much time discussing GPE stuff on IRC. I did find time last night, however, to reply to the backlog of technical support queries from people who'd read my Linux-on-laptop page. And today I found myself arguing the 'free fonts' thing again, though I'm unsure it's worth following up a new reply which snips most of the points I made and tells me, 'Debian is a waste of time.' (Sigh.)
Colour
While I was reading through the GNOME Human Interface Guidelines I came to the section on colour-blindness, which links to Vischeck. I found it interesting to see there images adjusted to simulate how they appear to colour-blind people, and images adjusted to make contrasts visible to colour-blind people that they otherwise wouldn't be able to make out.
That all reminded me that I had trouble with a few of the colour-blindness test cards when I was a child, and a search brought up several sites with Ishihara test patterns and other similar images. I certainly don't 'pass' all these tests, but this is of course desparately inconclusive - my monitor's definitely not colour-calibrated, for a start. It would be interesting to find out tomorrow if my flatmate gets any further with the same images on my screen: given that she's female, she's very likely to have 'normal' colour vision.
