That's why I use VIM. It removes the possibility of evil. :P

You really should re-train yourself to use ":x" - you could be saving an entire keystroke per IM message!

Apparently the term "nano-scale" means that your manufacturing process has features measured in nm. Even if that is 400 nm or 1000 nm it seems. Example: https://nano-cemms.illinois.edu/materials/3d_printing_full Quote 1: " . . . incredibly thin polymer layers (on the order of 400 nm) . . . " Quote 2: "This activity demonstrates the basic challenges of nanoscale engineering and manufacturing."
