On Thursday, I read Karim's most recent article with Ned Gulley called, "The Determinants of Individual Performance and Collective Value in Private-Collective Software Innovation". Naturally, this wasn't a wiki-like contest, but there sure was plenty of reuse (R is an established platform), code recombination (Chris + Will + Koen + Mine). In this case, however, I suppose you could say the goal was to increase the "free-rider" problem. That, or I just think it's cool to have a portable R-based gadget. :-)
Ps, totally random aside, this graph is awesome, it proves that multiple people working together for a common good get a lot farther than any one person by themselves (obviously this is true, but this is quantitative, numerical evidence):
On Friday, I posted a quick blog article about porting R to the Beagle & Angstrom platform. Chris thought it would be very difficult, I thought it would be impossible, and so I offered $1,000 to anyone that could help.
On Saturday, I got about a dozen emails, and 3 folks who said they were going to try (4 if you include me, since I figured maybe I could do it after all).
On Sunday, I got an email from Koen with the following picture, and code screenshot printout:
Total elapsed time since blog post: less than 36 hours
Naturally, I wanted to make sure I could replicate it myself, and so I was able to run the following commands on the BeagleBoard (with a wifi internet connection up and running):
opkg install http://www.angstrom-distribution.org/feeds/2008/ipk/glibc/armv7a/base/tk-dev_8.4.19-r0.1_armv7a.ipk
opkg install http://www.angstrom-distribution.org/feeds/2008/ipk/glibc/armv7a/base/gfortran_4.3.1-r11.1_armv7a.ipk
opkg install -force-depends ./r_2.11.1-r0.5_armv7a.ipk
And then I popped it up, and got this:
2shay, Koen :-)
UPDATE: I just Googled around, and there was apparently also another possible solution, cooked up by HNS, although technically not doable with Angstrom (which is critical given some of the drivers and whatnot I've patched into my version of Angstrom), it gets R up and running with Debian:
---Copied from the mailing list---
Does this qualify as well?
Install Debian Lenny, u-boot and a kernel on a SD card from
boot and login. Make sure the host works as a internet router.
