comment Hide dot and dotdot (“./”, “../”) directories in NERDTree gVim
A feature taken intact from earlier file systems and on display in unix. Not sure if it originated with unix or comes from even earlier in the history of computing (multics, maybe?).

comment I just ran rm /* accidentally, any fix?
Of course you need to be able to stop using and unmount the affected volume as soon as possible if you want to go this route.

comment How do I physically prevent people from unplugging an Ethernet cable?
"Cable ties are a great idea, but they can be easily cut with scissors or a knife. " If you assume users with knives to hand (you should, I have one more or less all the time) then these same users can as easily circumvent this as the cable tie: tip goes in, cable comes out. Perhaps more easily as the motion to release the jack is small and require no appreciable strength.

comment Is a process PID guaranteed to stay the same as long as the process doesn't die?
That is, of course, strictly true, but that simply reflects the definition of "process" that the OS uses. The user will see a continuity of state with a changing number, and if she was counting on the presence/absence of the PID to determine if some state was present on the machines this would be a problem. That's why I called the behavior malicious.

Well, a malicious programmer can break the guarantee, but this is generally true of well behaved programs.
