Rpy2 on ubuntu

python -m 'rpy2.tests' was failing because libR.so wasn't being found when using the latest dev version of rpy2 installed in my home directory.

Ugly, simple fix: sudo ln -s /usr/lib64/R/lib/libR.so /usr/lib/libR.so

printer overspray

Sarah enjoys digital scrapbooking, until she wants to print a carefully-aligned page. If the page is 8.5x11 inches, then one would expect borderless printing to be exactly what she wants. Um, not so much. For borderless printing, printers expand the image slightly to avoid alignment issues, assuming that people won't mind if the edges get cut off slightly. (http://www.steves-digicams.com/knowledge-center/size-matters-paper-size-vs-print-size.html) Our HP deskjet 5400 has an "overspray" setting that can be turned off, which at least ensures that the entire image gets printed.
