Linux, C++ audio capturing (just microphone) library

Port a Rails App from Windows to Mac or Linux

Linux: page faults and network filesystems

If a Linux system runs out of physical memory, does it drop inactive executable code pages? I assume the answer is yes, since there is no reason to keep them in swap, so they are simply discarded and re-loaded if necessary (as far as I know, that's what FreeBSD does).

This can be "fixed" by running chvt 1; chvt 7 in a script in /etc/pm/sleep.d, such that those commands run on thaw and resume. However, the X console is not always vt #7, so chvt 7 is wrong in those cases. What I would like to do is find out...

PIL's Image.show() brings up *two* different viewers

When toying with images in the python shell, I use image.show(), where image is an instance of Image. Long ago nothing happened, but after defining a symlink to mirage named "xv", I was happy.
