How to protects Linux and Unix machines from accidental shutdowns/reboots with molly-guard

How to protects Linux and Unix machines from accidental shutdowns/reboots with molly-guard
Oops! I did it again. I thought I was logged into my home server. Turns out I rebooted the db server. Another my not so favorite is typing “shutdown -h 0” into the wrong terminal. I know a few people who have admitted to doing that here.

My anger that can't be contained
Is there any end to the madness? Do I need to suffer from accidentally random reboots and shutdowns? After all, it is human nature to make mistakes, but one should not keep on making the same mistakes again and again.

How to install pandom: a true random number generator for Linux
This tutorial explains how to install pandom: a timing jitter true random number generator maintained by ncomputers.org. The built-in Linux kernel true random number generator provides low throughput under modern circumstances, as for example: personal computers with solid state drives (SSD) and virtual private servers (VPS). This problem is becoming popular in Linux implementations, because of the continuously increasing need for true random numbers, mainly by diverse cryptographic purposes.
