First post this year, yikes! The last one was about ESUG 2010 in Barcelona, now I just returned from ESUG 2011 in Edinburgh. While I was there, a package with the shiny new XO-1.75 prototype arrived.
Incredibly, the pre-installed Etoys simply worked! Never mind the change in processor architecture, the Fedora folks have done a great job compiling the Squeak VM for ARM and so Etoys just works. Of course that's just as it should be, but it's still awesome. And e.g. Squeakland's own Etoys-To-Go would not have worked, as it only includes binaries for Intel-compatible processors.
Another great addition is a 3-axis accelerometer. The Linux kernel's driver exposes it as a file at /sys/devices/platform/lis3lv02d/position. Gotta love the unix design of exposing devices as files. All it took to make this usable from an Etoys project was just an object with ax, ay, and az variables that get set with one simple textual script:
Also, uploading from Etoys directly to Squeakland using Wifi just worked. Yay!
Update: If you want to try my uploaded project on your XO-1.75, you need to save it once from Etoys, quit Etoys, and run it again. Otherwise it won't work - it was signed by my key so the Etoys security sandbox prevents it from opening the accelerometer device. The saved copy will be signed using your key so no sandboxing happens.
