I’m at Tokamak 3 in Randa where Mario is hosting us. First of all, thanks to Mario: everything is perfect!

Great landscape surrounding us

Great landscape surrounding us

During the last days we had presentations, meetings and talks. The GSoC projects are being merged in trunk (a lot of great features coming: new widgets explorer, mouse plugins, remote widgets, plasmate), the netbook stuff is going on, Qt stuff being solved, etc..

I talked about QGraphicsAnchorLayout, the new layout engine that will be present on Qt 4.6 and even did a small demo about that. We are nailing down the remaining bits (API, bugs) and hopefully we’ll have an awesome layout engine to create rich UIs when Qt 4.6 comes to “the streets” !

I’m also working with Alexis (darktears) to debug some problems that we’re facing with the raster engine on embedded devices. The thing is that the performance was not so good as it was in 4.5.0 and we’re tracking down where is the regression. Besides that we already tested Qt 4.6 on some hardware that we have here and the performance is much better than 4.5.X (regarding GraphicsView). While we wait Qt cross compiling, I’m also updating the pastebin applet to provide a nice dataengine/service so other plasmoids/applications can take advantage of this.

Until now, it has been a great sprint with lot of work being done on Plasma and on Qt 4.6. It’s awesome how much our speed increases when we are together! ;)

  1. Well that’s an excellent landscape :D

  2. Nice picture, but saddly to small to be an Desktop.
    Is there any chance to get an highresolution to download ?

  3. @Ralf: check my flickr for a high resolution picture: http://www.flickr.com/photos/morpheuz/

  4. On N810 we found out that 4.5.x raster gs is slower than 4.5.0 because the MIT-SHM is switched off for 16 bit color.

    Our patch is here:
    http://qt.gitorious.org/+qt-maemo-developers/qt/qt-maemo/commit/74c72040c577a80233a61d366f6c61af132e4e06

    Let me know if this helps you.

  5. Yes, we have Alexis here (troll) and he pointed out to a commit on 4.6 that fixes it :) It’s basically the same commit. :) We just wanted to profile it to see how much improved. Thanks for the info though!!! :D
