I stopped taking your article seriously when I realized you said that 80000 KB == 80MB. It does not. 80MB == 1024 * 80.
You have a Ph.D and you can not do very simple byte math?
Yes a tempfs is better because if it runs out of space it can use the swap. If a regular ramdisk runs out of space you're screwed. Not that it likely would, but still.
Also, Linux sometimes caches IO -- unless you tell it not to -- so really you're not gaining all that much here.
If you're going to throw your logs into a non-trustworthy ramdisk you might as well turn your syslog off.
