Qt Designer and subclassing QGraphicsView

From http://doc.trolltech.com/qq/qq20-jambi.html

The display is implemented by subclassing the QGraphicsView class. When using Qt Designer to create our user interface, this custom widget is unavailable to us. But it is still possible to include the widget in the user interface definition by "promoting" one of Qt's regular widgets as a placeholder for it on the form we create in Qt Designer.

So, when designing the user interface, we put a QGraphicsView widget onto the form, Then we open a context menu over it and click Promote to Custom Widget. In the dialog that opens, we specify the name of our subclass: QtanoidView in this case.

Roulette Ruby

Assumptions:
- we get double our bet back when we win
- we reset the bet to 1 when we win
- we leave the bet at the maximum bet of $50 when we hit it
- we double our bet each time we lose (this is the theoretical lynch pin in that you can win back your previous losses eg. you lose with bets of 1,2,4,8. Then you win with a bet of 16. So total profit is 16 - 8 - 4 -2 -1 = 1. So you never really lose. Until you hit the table betting limit.)
- we keep betting until we run out of money or we make 1.05 * initial bank

This is the highest win ratio but the wins are so small that one loss wipes them out.

Real time physics simulators

From http://users.softlab.ntua.gr/~ttsiod/games.html

I want to "lure" my nephews and nieces towards science and engineering, and one of the things I've done towards that goal is to code some real-time physics simulators.

Waves... (they look much better when they move :-)

All the code I wrote is available below, and compiles under Linux, Free/Net/OpenBSD, Mac OS/x and Windows (with GCC/MinGW), with the usual...

Git

git

git reset --hard HEAD
git checkout master
for i in $(git rev-list --reverse origin..master) ; do git cvsexportcommit -W -c -p $i; done

$ git cvsimport -i
$ git rebase origin

$ CVSROOT=$URL cvs co module
$ cd module
$ git cvsimport
hack, hack, hack, making two commits, cleaning them up using rebase -i.
$ git cvsexportcommit -W -c -p -u HEAD^
$ git cvsexportcommit -W -c -p -u HEAD

HTML5 Canvas Experiment

Click here to launch the experiment! (beware: sophisticated browser needed)

HTML5 is getting a lot of love lately. With the arrival of FireFox 3.5, Safari 4 and the new betas of Google Chrome and Opera, browsers support some great new features including canvas and the new audio/video tags. Most interesting: modern mobile devices like the iPhone or Android-based phones also support new standards in favor of Flash. The future looks bright for HTML5.

Time for us to play with this technology. We've created a litttle experiment which loads 100 tweets related to HTML5 and displays them using a javascript-based particle engine. Each particle represents a tweet – click on one of them and it'll appear on the screen.

The original particle engine was ported from a Flex/AS3 project that we've created to javascript. We're using processing.js for particle rendering on canvas which is a very useful graphics library created by John Resig. The music will only be played if the browser supports the audio tag. To detect if the audio or canvas feature is present we use the awesome modernizr library. We could have used a fallback solution like playing the sound via Flash. But this experiment is about HTML5 – and who needs Flash anyway?

Big thanks to spokenlounge.com for supporting us and for providing the mp3 track.
