NetBookPro(s)
Thanks to Liam IL#039;m now able to test my toolchains on machines with some more RAM:
The netbook pro with case:
CPU (rev = 0x6) clock 400 MHz
Psion Teklogix netBook Pro MLB rev. D (board ID 2)
NAND flash: 64 MB (Samsung K9K1216U0), 3 MB reserved for OS partition
RAM: 256 MB
and the net:#039;bookl#039; PCB:
NAND flash: 32 MB (Samsung K9F5616U0B), 27 MB reserved for OS partition
RAM: 128 MB
The next step is to get an EABI kernel running and help Florian with updating the OE support for the nbp. After that I can install a toolchain + distcc on my arm machines and starting building R, octave and OOo.
Below is a picture of the netbook next to a zaurus SL-C700:

Taking pictures of the moon
A while ago I got the second cheque from google and bought a Sigma 1.4x teleconverter. A teleconverter multiplies both the focal length and aperture of a lens, so you gain extra e#039;zoom9#039;, but you also lose some light. The moon looked pretty full tonight, so I put the teleconverter and my sigma 80-400mm on my camera, set up the tripod:

After a while I rexhanged the 80-400mm for a canon 70-200mm F4L:

The 70-200mm seems to give better image quality, but doesnE#039;t 1#039;zooma#039; as far as the 80-400mm. Next time I0#039;ll use a sturdier tripod and hopefully Iq#039;ll be better in metering the exposure. Damn you, 20D, for lacking spot-metering!!

Mirrorball panoramas
When I was buying some flowers for my grandmother (she just turned 84) I noticed that the store also sells mirrorballs! After delivering the flowers and some coffee I openened my powerbook and followed the mirrorball tutorial:

I really like the how Cubic Converter is constructed. If it werenI#039;t for CC I would have wasted a day writing code in matlab to map the spherical image into a cylindrical image :)

Cairo performance improvements on ARM
Thanks to a patch from Kalle Vahlman cairo-perf-diff-files compiles again and I ran it against the performance results from last week (1.3.2) and today (1.3.5). This is on an ipaq h2210 running Ångström:
