Comments, Code and Qt.

QtOpenCL tested on my old machine

Qt Labs posted today an interesting blog post about OpenCL and how Qt will help developers to make OpenCL easier for them.

OpenCL is an open standard and a framework developed by nVidia, Apple and ATI that let’s programmer run a piece of code on the GPU (or in parallel simultaneously on the CPU too). The power of OpenCL comes from the fact that our GPUs are much more powerful than the normal CPUs and they are massively optimized to run code in parallel. By offloading the CPU from heavy calculations and by running the calculations in parallel on the GPU, we can achieve some very impressive performance boosts. I’ll present the results on my machine below.

Playing around with QML, Part 1

I have been intrigued by QML ever since I saw the first demos online at Qt Beta Labs. Creating beautiful UIs, fast and with great animations is not easy with the current programming tools at hand. This is arguably the problem Qt is trying to solve with QML. I think they are doing great and this is the way to do UIs in the future, but I found some interesting issues with QML while playing around with it last evening.

So far I have only seen a few demos online of QML and they are mostly from the Qt guys themselves, but last week I saw a demo that Digia presented at MWC in Barcelona done in QML (or Qt Quick as I think it should be now called). Looks nice! If you know of more QML demos that are available online, please let me know. But since there really aren’t too much stuff yet done with QML, I decided I need to test it myself. I have already in the past read some documentation and gone through the QML demo applications in the Qt Kinetic source package so now it was time to play with it for myself.

Nokia UI Extensions for Mobile compiled in Ubuntu and Maemo 5 SDK

Nokia has released a technical preview of their second Qt and C++ based UI Framework (the first being Maemo 6 UI Framework) called Orbit or DirectUI, this time with the name UI Extension for Mobile. Source code is publicly available under the LGPL license at Gitorious: http://gitorious.org/uiemo. I need take a closer look at the source code, but my initial impression is that the APIs are clean and very Qt-like. Nice job!

A proper Twitter client for the Nokia N900

kypeli — Mon, 25 Jan 2010 16:52:34 +0000

I use TweetDeck on my PC as my Twitter client and before that Gravity on my Nokia 5800 S60 phone. But I haven’t yet found a proper Twitter client for my N900. Mauku has been there since the beginning and Witter is one of the newest additions to Twitter application on the N900, but both of them seem to be still work in progress and lack some important features. I am a fairly active Twitter user (Tweetdeck is occupying my secondary monitor on my PC ) so naturally I have been waiting for a proper Twitter client for my N900 too.

My new professional blog

Welcome to my new blog. I already have an other blog hosted at Blogspot, but I decided to move my blog to en other hosted server I have better access to and use WordPress as the publishing platform. I got some very nice experience with it after we set it up at work for an internal project. It really was 5 minutes and everything worked. Amazing!

A week with the Nokia N900

kypeli — Sat, 17 Oct 2009 14:45:00 +0000

The Nokia N900 is probably the hottest new mobile device out there right now. I received my N900 a little over a week ago at the Maemo Summit 2009 in Amsterdam. As you probably already know, Nokia was kind enough to give an N900 for a 6 months loan to every summit attendee so we got our N900s well before anyone else. You can only imagine the amazement in the crowd when Vice President of Maemo Devices in Nokia Mr. Ari Jaaksi announced the news in his key note. Nokia just got 300 very happy community member friends!

Yes, I have finally finished my Master’s Thesis. And I must stress, finally. Some spell checking might still occur and I will print it next week. But I am quite pleased with what I current have. I am more than happy to receive any feedback and comments on my theses!
