Gaussian: add 'Density=Current' for post-HF

Do your electrostatics / population analysis from some expensive post-HartreeFock calculation look suspiciously similar to the HF result? You probably forgot to add ‘Density=Current’ to your input stack. I don’t understand why this isn’t the default, as when you are doing (hybrid)DFT calculations, the SCF density is being varied, thus the pop / electrostatics output change with functional.

Pymol Ray Tracing without wasting time

I often use the nice built in ‘ray’ raytracer in Pymol. These ray traces can take minutes to hours, and during that time I of course want to use my computer! Unfortunately, the Pymol window freezes during the ray trace, so when I switch virtual desktops it sometimes looks as if there’s a frozen terminal or similar there, which I click on, sometimes inadvertently, sometimes because I am a fool. This click gets queued up to Pymol and promptly delivered as the ray trace finishes - making the window redraw with the built in opengl, wasting all the time ray tracing, arg!
