Thanks to some great work by Sam Magnuson, QSystemTrayIcon::showMessage() will support Growl on the mac in Qt 4.3.

And on […]

I’ve put up a new version of qdasher (qdasher-20061124.tar.gz), the Qt4 port of Dasher. I’ve managed to get it down to about 20% CPU usage when running in fullscreen on my standard Pentium IV machine. It runs nice and smooth on our embedded hardware.

How to design APIs for XML is debated daily, and has been done so for long. For too long. Now ages ago, companies formed at W3C to design the DOM, using language neutrality and document editing with load/save persistence as goals(it seems, and some says).
