I think we have more urgent things to work on that speeding up graphics right now -- like making sure all Darwin parts are actually printable with the current system (!). "Does it actually print?" is more critical than "Can it go faster?" for an initial system release. However, if someone not on the core team wants to work on that kind of optimization and submit patches once they have sometby jmarsden - RepRap Host

The issue isn't so much the building, which is now highly automated (I could build nightly and upload a .zip somewhere from a cron job, if I wanted!).

And perhaps you'll bulk-ship a few tens of such kits across to Zach for the RRRF store, or something, for people on this side of the Atlantic?

I'm no good at PR. Fortunately, others are! Here's a PR email about a talk I'm giving this Saturday (I didn't write this, or ask for it!). Other Reprappers and potential Reprappers are very welcome to attend! BTW, I don't have full Reprap hardware to demo, just the electronics and a stepper.

Joost, Thanks. The libraries are all the same, so I'd be surprised if going from 0.8.1 to 0.8.3 breaks Java or causes new bugs to appear in the libraries... but a test would be a lot better than my guesses :-) BTW, I think you meant Ubuntu 7.10, the "10" is the month of the release, October.

Interesting. I have no dual CPU machines I can test on. If this *is* related to number of processors in some way, then booting a uniprocessor kernel might be worth trying as a test?
