You mean how the "capacitors" are just etched parallel wires and the silicon is used as the dielectric?

Not just parallel-plate capacitances exist, there are also significant junction capacitances. Reverse biased PN junctions, basically diodes, are used to isolate the individual devices from the substrate; every reverse-biased diode is also a (nonlinear) capacitor.

swap_size = min(2gb, max(512mb, phyram * 2))

With more than 2gb your machine will surely crawl due to massive disk storms, with less than 512mb the Linux VM may not be happy (sometimes it just HAS to swap or go to the oom-killer). 512mb is probably overkill to prevent that scenario, but that's what I use.
