Scratch Pi testers?

Are there any of you out there that would like to do some Scratch improvement testing? You need a Pi running Raspbian (though I guess it might work on other unixish OSs?)

Got a Pi with raspian here…

I am willing to help, but I am not a Scratch user and would need some guidance.

It looks like there are tutorials and lessons for 1.4 and 2.0. Should I care which ones to use?
My approach would be to work through published material and see if I can get them to work as expected.
This looks like a good starting point http://blogs.wsd1.org/etr/?p=395

Is there any new behaviour that needs to be tested?

What is your planning horizon?

1.4 - 2.0 is (spit, hack) Flash based and totally irrelevant to Pi. The only good Flash was Flash Gordon.

The www.raspberrypi.org forum on Scratch has useful stuff buried in there. The scratch.mit.edu forums have a lot of older stuff still valid. 1.4 getting started and reference guides are still at http://scratch.mit.edu/scratch_1.4/ There are some relevant videos on yootoob.

I'm not adding any new facilities right now, just re-writing sections of the code to speed things up and moving the code to post-closures images.

for an idea of how that is going.

Continuous gentle improvement is the plan. I'll publish new images and /or VMs whenever I think there is something worth getting checked out. I already have a couple of Scratch/Pi users in the UK that are using it in their classes, but they're teachers and not at all Smalltalk knowledgeable, so they have an intriguingly different set of views, needs and skills. A few people with Smalltalk knowledge would be a valuable addition to the team.

If you download https://www.dropbox.com/s/m34nzzkfg9u8jtn/Pi-Scratch-013-test.zip and unzip it in a suitable directory, then cd there and run
$ squeak -vm-sound-alsa Scratch-GPL-013.image
things should work. Note that one of the UK teachers had no problems, the other hasn't made it work, so there may be some issues to be worked out.

Maybe. I must admit that I'm not terribly familiar with Scratch, which means I'm a bit numb to expected behavior.

Are there any existing SUnit tests for it?  If so, examining them might reveal clues about which parts of the system were worrisome to folks who'd been there before.

Going at it cold, I kind of wish there was some tool that could measure e.g. cyclomatic complexity or *something* to clue me in on where the rats (mice?) are nesting.

Blah blah anyway wishful thinking. Can you possibly send me a list of methods you've changed? Or have you been working exclusively in the VM?
