Medical images are typically stored in DICOM files which transport the information used for taking the X-ray image (X-ray energy, pixel-size, patient name and birthday, type of exposure). DICOM is a huge standard that also includes 3D imag

I think this is a slight update of http://news.ycombinator.com/item?id=4035748 where a lot of the obvious questions (JTAG? Over the Internet? Is it a maliious backdoor or engineering/debugging leftovers?...) have already been discussed.

I second the recommendation for Reaper. For the technically inclined user it's extremely powerful, but it (and the included powerful, but even more abstract plugins) often lacks useful defaults. I use and like it a lot. It should be said th

One of the big advantages of Git over Subversion in a teaching context is that, due to it's decentralized nature, every git repository is fully self-contained and stands on its own. So for experimenting it's much easier to create a git repo

Decay of nuclei is a completely random process, and you really don't want to use it to define a time-scale. What you had in mind is the SI-definition of the second, which reads ( http://www.bipm.org/en/si/si_brochure/chapter2/2-1/second.ht.
