Hey, Trolltech has dumped bits of Qtopia into the public. As it is not too nice to say bad things I will just say what is missing and what a personal roadmap could look like if there would be a possibility that these things can get upstream… What is missing: Safe Execution Environment (SXE). Probably they don’t release because security through obscurity rocks? DRM, another case of security by obscurity? licensing? One should look into SUNs (L)GPL DRM stuff if…

Hack/Product of the week, worker of the month all hail Jacob. Patching RTP sequence numbers and session id’s in RTP and RTCP to dynamically switch video streams on broadcast site without confusing players on the clients. Nice hack and see you at ITU Hong Kong.I need to sniff the USB Communication of this dongle to get rid of Windows on the device… but there seems to be a good software tool to get this job done. Sadly the lab was…

I’m exposed to an UMPC for two days and I really hate it. I wonder how companies can sell such things. Not even a freshly liberated, booted from haret, PDA running feels that crappy. The list of annoying things is so long and it is getting longer by second. You can not use most of the installed applications as they failed to make keyboard input working, the hardware cursors keys are not rotated when you rotate the display, dual display…

This week I was introduced to the mini bar and enjoyed talking. PyPy vs. smalltalk. Okay in contrast to my prior believe something PyPy is not that new. smalltalk to slang looks conceptually similiar to python and RPython. And smalltalk is implemented in smalltalk just like PyPy in python and there is a tool to create C code from the smalltalk image effectively creating the SmallTalk VM. I should look more often into design patterns. With the new BitBake parser…

DVB-H is still IP based, but the lower levels of DVB-T and DVB-H are pretty similiar. I felt bored and wrote a simple mpeg soft demuxer that can extract PES and PSI. But now when DVB-T and DVB-H are mostly compatible where is the IP? Well it is inside the DSM-CC private section inside the Multi Protocol Encapsulation (MPE). So I felt bored and wrote this multiplexer, I analyse the DSM-CC private tables and inject the payload of the MPE…

For another A-Team like fair project we built a mosaic of Images, live h264 videos and html sites on a huge 42″ LCD panel. You have three rows with four columns and place an image, video or webbrowser widget at any position. Displaying the video and the image is quite easy. But the browser was a bit tricky. So my first choiche was Python and KHTML. Well KHTML is attached to KIO and other services. So I found this python…

Wow, what a day. Today was the “Conference on open-source mobile phones mobilizes”. And OpenMoko here and here was announced. Also the OpenMoko.orgwebsite lacks the glamour of the usual announcements it has something true geeks will love. It has Web SVN, and yes it contains the source for all these things they announced and even datasheets. To use a sentence the Qt Community Manager uses a lot. FIC and OpenMoko.org just get it. They know what geeks like and need….

Happy Birthday lovely Qtopia. It is another year you are truely proprietary. The last GPL release, patch release rsync version of Qtopia was one year ago. One year without a patch, update and only five to six releases of the commercial edition. Anyway Qtopia is still my all time favorite of proprietary software and I still believe there will be a GPL release of Qtopia in the future and I hope soon really means soon.But for now happy birthday lovely…

Determining the Quality of OpenEmbedded is quite hard as we depend on 4000 pieces of software. So OpenEmbedded quality is aggregated from the quality of all such independant projects. To make things worse we use these things in many different combinations. By guess we have +10 target distributions +30 target machines, +4000 package/build descriptions and we should work on all available Linux distributions and somehow even non GNU UNIX platforms. I don’t want to do the math to think about…

There are two aspects of Software Engineering that currently interest me most. One is taking Usability into account when creating applications. What tasks needs to be solved, who is our target user, how often are these tasks executed. All these questions will heavily influence the User Interface and behaviour of your application. I started as a geek adding geek features to applications. So dear lazyweb and specially Free Software developer. If you write a new application ask yourself what these…
