Hi all.
There's been a newer version of artisan released today with small changes.
Changes:
- improves performance of push buttons
- adds device external-program
- adds trouble shooting serial log
- fixes Linux Ubuntu and other bugs

Heyyas,
first off - thanks to all the contributors of this project for the
wonderful program. It still has its flaws (coding style/organization)
but the functionality and idea are both just great!
However, i'm afraid i currently cannot use Artisan to aid my roasting
even though i'd really really love to. The problem is that the
performance of this huge blob of code (according to a quick profiler
run) in the matplotlib redraw code - which draws *everything* everytime
a redraw is issued. The result is that when i have ~20 events, and a
full ~18min roast curve (sample interval: 1s) a button press takes
almost 3 minutes to reach the assigned action. When i press "Drop" at
18:30min the event is put at ~21:30min. The timer in the upper right
corner updates every ~2 minutes.
This is ... well, not quite useable. The machine i am running this on is
far from bleeding edge, yes, but also far from beeing old. It's a 1.6gHz
Core(1) Duo with 3GB of RAM running a testing Debian Linux with recent
py-qt, python and matplotlib versions (i've even tried python 2.7 and
psyco to speed things up).
Even on my Desktop box (which *is* bleeding edge with a quadcore i7 and
8gb of ram, software ~same as laptop) the program runs unbearably slow
after logging a while.
I'm not quite sure what the cause of this is. I've tried putting the
tgraphcanvas.redraw() method in a own thread, it helped only marginally
(and python did never use more than ~105% cpu, which i found quite
strange).
The Version i am running is SVN-r712.
Where could i start debugging this problem? Any help would be *greatly*
appreciated!
Thanks again, Best Regards

Exeception Error: redraw() clf() got an unexpected keyword argument
"keep_observers
I am using Ubuntu 10.04 LTS
artisan_0.5.2-0_all.deb is installed.
By starting artisan I get the error message below.
What does it mean?
The left axis is also wrong. It is still by 0-700° instead of 225 -
245°
Thanks a lot
