There is a bunch of code out there (which can be copied and pasted) to grab the acceleration values from Nokia N900. Here I contribute one more, it’s Qt-based and using the QtDBus module. The values in x, y, z will have the unit of G.

Qt documentation mentions QPalette as the class that contains color groups, Active, Inactive, and Disabled, for each widget state. Knowing the color for many different color roles is important. For example, a style author might want to tweak the colors of each buttons depending on QPalette::Button, ...

Time for X2 premier, like I promised before.

I know the number of Qt experts out there is growing (like crazy). Still, I believe we should do more to help people master this great framework. I am aware that I might bore you with few Qt code examples I did last year or even the year before, but somehow I feel that I won’t do no harm if I keep s...

The following scenario is quite typical. Your family member, spouse, or coworker has this fantastic, powerful, brand-new multicore machine which, for some reasons, has to run Windows or Mac OS X. On the other hand, you probably have some el-cheapo laptop which is also wonderful but it lacks the proc...

The other day, I couldn’t resist buying the el-cheapo Athlon 1.6 GHz-powered Acer Aspire 5532 in BestBuy for $330. With its 15.6 inch screen, seems that it is quite a nice bargain. It comes (of course) with Windows 7 Home Premium, but after slapping openSUSE 11.2 DVD I got from the last Camp KDE (mu...

Again, just track all the tweets and blogs to know what happens in Camp KDE in almost real-time. For more pictures, check out KDE Events Pool at Flickr.

Showing up at this year’s Camp KDE feels a bit weird. First of all, because I do not need to travel at all since I already moved to San Diego some time ago. In addition to that, while I was still with Nokia (Qt), usually I could only attend conferences only if I have something to present. It is a gr...

As I have hinted before, somehow I aimed to move to some sunny place in California. Well, lucky as we could be, after days of experiencing the transient stage (with tons of good and bad experiences, what a roller-coaster), we slowly settle in San Diego, (arguably) a beautiful place to live. The proo...

While enjoying this vacation, I managed to steal few hours to do some fun coding. Nothing spectacular, but it yielded something I will surely share in the near future. However, since I am still in the mood of bombing the planet again, here is another post with food pictures.

Somehow the wind finally leads me to Bandung, the place where I spent years studying at ITB. While still trying to absorb all the deja-vu sensations (last time I was here, when I left the place, was 6 years ago!), nothing beats having breakfast (and potentially also lunch and dinner later on) in one...

One thing which recently made it into my reverse-culture-shock impact list is the widespread use of incomprehensible (read: broken), mixed-language expressions, potentially due to many reasons (to name a few: innocent show-off, following the mainstream, or just trying to look more “educated”). It st...

I came to Trolltech (then became Qt Software, then Qt Development Framework) early last year, at the time when the Trolls were busy stabilizing Qt 4.4. I was assigned to work on QtWebKit, so right from Day 0, I did carry out my best patching skills and committed my burst fixes as fast as I could. Qt...

That is, 2009 is coming to its end. Some parts in Central Europe already enjoy the snow although Oslo still has a touch of autumn feeling.

Some of the slides from last Maemo Summit in Amsterdam have been made online. Here is the one from the Cross Platform with Qt talk that I held. It does not give much, though, since mostly what counts is the real live demo. Let us hope that at some point in time, the recorded videos will be online as...

Though Google Chrome for Linux is not yet officially announced, people have been working to make Chromium, the open-source version thereof, available for different popular distributions. I wrote before about CrossOver Chromium, but not only this is just a hack, it is also not up-to-date at all. The ...

The wave of cold weather is approaching us, the nature’s way of saying Wind of Change. While some parts of Europe enjoy the snow already, Oslo is relative still calm and actually enjoyable, even in the afternoon, for a walk.

After kickstarted on Tuesday, Qt Developer Days 2009 Munich has ended. Some of us, the Trolls, are already back in Oslo, recovering from the intense adrenalin kicks within the last 72 hours (or more). The extra surprise was to experience the first snow in Munich (and this is still mid October!). Mos...

Like I mentioned before, now I am in Munich for Qt Developer Days 2009. The training sessions started yesterday already, the plenary was initiated this morning as we had the keynotes from Sebastian, Lars, Walter, and Matthias. We are now in the middle of lunch break, the technical track will start v...

Today is the last day of Maemo Summit 2009. I am sure the news spreads quickly; everyone and his uncle know already that Nokia lends around 300 shiny N900 (preproduction devices), worth 500 EUR, to the summit participants, excluding Nokia employees and contractors. It’s Christmas in Amsterdam!

Like mentioned before, with other few Trolls, we are now in Amsterdam for the Maemo Summit 2009. If you are there, don’t forget to look for us and/or drop us a visit!

Something I can always be proud of is to be part of the Nokia QtWebKit team. The fact that we are all the WebKit reviewers from Nokia (at the moment, surely the situation will improve in the future) is one thing, but most important is that the team is small and agile, and it comprises great hackers....

Finally I had a real vacation, albeit short. Like many typical holidaymakers, I decided to do a little tour passing three selected cities in Europe, at the same time also using the chance to practice light, one-bag travelling (with a great success, mind you!).

Another exciting event coming up soon: Maemo Summit 2009! This time it will be in Amsterdam. My flight ticket is secured already, I look forward to it. And of course, since this will be also my first visit to Amsterdam.

Seems autumn always calls for my service, hence the usual pizza-baking obligation, as evidenced from the photo. Recipe? Check what I have posted last year. A slight variation: slices of pineapples 🙂

This slick stuff is mostly educational (for the lazy, see the 30-second YouTube video courtesy of Alessandro). With all the accelerated graphics (with those alphabet soups) these days, who on earth uses ray casting for real-world apps? Nevertheless, since I still keep the piece of code (read: a func...

Happy Eid Al-Fitr to all !

A few weeks ago, just for a change (between the usual QtWebKit bug-fixing and patches juggling), I did take a look at our QtSvg module. According to some internal reports, QtSvg is not fast enough when parsing a large and complicated SVG. Of course, slow is relative, slow to what. And arguably, pars...

Often I ask myself how long I would still want to stay in the software industry. Before I started my professional programming career, I never thought that this wonderful world of software craftsmanship is full of complaints, frustration, anger, and hostility. Perhaps that is just the reflection of p...

If you were at my Special F/X talk, Desktop Summit in Las Palmas, or if you watched the recorded video (135 MB Ogg), you might notice the tongue-in-cheek gratitudes to Lufthansa dan SpanAir I expressed at the beginning of the talk. The story goes as follows. As all of us, the Trolls, left Oslo to fl...
