Hi,

I have been assigned to another tasks so there is only one week left
on processing.  I'll see what I can do within it.

what have I done this week:

a processing loader listening to requests on dbus.

which means we can use dbus-send to ask the loader to load our app and
execute it.

this reduced the load time from ~10 secs to 1 sec.

how to test it:

0. (optional) update cairo on neo.  I built 1.6.4 myself.  It's a lot
   faster so I'll probably push this into OE.

1. opkg install libdbus-java
   opkg install ibmatthew-java

2. binaries: http://people.openmoko.org/john_lee/processing, download
   the directory to neo.

3. open 2 ssh connections, set DBUS_SESSION_BUS_ADDRESS.

4. ./processing-server on one connection, wait "Server ready."
   ./processing-lanuch ColorWheel.jar on the other one.
   (or SineCosine.jar)

5. the first start is slow, after that it will be faster.

what am I still doing:

more profiling indicates that I have to look into jvm for further
improvements.


Regards,
John
