Today I'm joining the rapid fire blogging squad.
- Roberto is moving back to Italy and last Wednesday was his last day at the office. Roberto is one of my best friends at Trolltech so I was incredibly bummed out by his departure. The office won't be the same place without him. Plus who will help me hack on a prototype GLSL jit engine that I wanted to do some research on? (rhetorical question, I'd only trust him with that anyway)
Roberto is also, by far, one of the best hackers who ever worked on KDE so I'm very excited to say that Roberto and Trolltech came to an agreement by which Trolltech will sponsor Roberto for two days of the week to work on KDE.
- This has been a bug fixing week so I didn't have any time to work on WebKit. Last week I did manage to finish off integrating SVG into WebKit Qt
- For the last two days I've been thinking about adding basic high dynamic range color support to Qt. QColor is already suitable for it and extending it wouldn't be a big issue. QColor's internal representation is a union of unsigned shorts. Basic HDR support requires 64bit, where every channel is a so-called, "half". Half values have 1-bit sign bit, 5 exponent bits, and 10 mantissa bits. It's a format used, among others, in OpenEXR and Cg. In fact OpenEXR project provides a C++ half implementation under a BSD-like license. Along a CIELAB colorspace support that I wanted to add to Qt for a while now, support for HDR would open a slew of new possibilities. On a silly, desktop level - imagine a desktop background the is light proportionally to the sun-light that you'd see for your currently configured timezone. On a more basic level HDR is pretty much essential for any kind of image processing/editing nowadays. I'll most likely write another blog dedicated to color-theory and things I'd like to fix/implemented in Qt that are related to it. Google returns hundred thousands of HDR images so if you'd like to see what people do with it, you won't have to look for long. One of my favorite examples is New York at night by Paulo Barcellos Jr that can be seen on fickr here.
- During lunch at Trolltech there's only one kind of yellow cheese available. Climbing to the highest-levels of good-faith and stupidity I assumed the cheese would absolutely have to be vegetarian (many cheeses is still made with natural rennet, which is taken out of lining of young cattle's stomachs). Yesterday one of the people pointed out that it most likely isn't. Today morning I called Tine, which is the biggest dairy producer in Norway (and one whose cheese Trolltech buys) to ask them about the situation. The result was, that of course, the cheese is not vegetarian. If you're a vegetarian, do not eat cheese or any products containing it while in Norway. For me the bottom line is that for the last few months I've been having non-vegetarian cheese for lunch putting me right now in levels of pissed off/disappointed that I've never been at (you know that silly questions about graphics you wanted to ask me? you might want to wait with that a few days).
