On the list of things I always Google, is how to create a symbolic link under Linux. I just can't figure out a way to remember what comes first; the source or the destination. The man pages add to the confusion by calling the "source" the target. So, the rule of thumb I now follow is cp or mv semantics.
Its one of those things that after almost 20 years, I should remember. But it just does not go in.
It becomes interesting when junior programmers are watching how I do something and I end up googl'ing things that they know.
I use the excuse that it fees up more space for other more interesting stuff, a bit like some execs just ware T-shirt and jeans to reduce the number of things to distract them in the morning so that can concentrate on the important things.
