I've been slowly improving the performance of both web- and native-Decker since v1.0, and I'm pleased to announce that I've passed an interesting milestone: native-Decker is now entirely usable on my favorite Bim*, the OLPC XO-4:
The XO-4 is a rugged and repairable 1ghz ArmV7 machine that ships with an obsolete version of Fedora 18. I love it dearly.
The latest head revision of the Decker Repository can be built from source with the GCC and Libc that are available in standard OLPC OS images. If anyone else has one of these machines I'd be happy to provide more detailed build instructions.
I suspect that many other inexpensive Linux-based SoCs can now handle Decker as well. Happy hacking!
