I long ago decided I will never go to meetings again because I think face to face meetings are the biggest waste of time you can ever have. I think most people who work at offices must share my opinion on meetings. Nothing ever gets done. When things get done, you usually have someone come into your office to talk about it. But a lot of the time the real work gets done by people sitting, especially in programming, alone in front of their computers doing what they do best.

Why are there so many places (usually */?bin) to store executable programs in the linux filesystem? What are these bins intended for? Here is what I have found:

/usr/bin - generally accessible programs
/bin - programs needed early in the boot process
/usr/sbin - programs reserved for the system administrator
/sbin - programs reserved for the system administrator and needed for booting

Like all other Linux related development, the work to write this manual was done on a volunteer basis: I did it because I thought it might be fun and because I felt it should be done. However, like all volunteer work, there is a limit to how much time, knowledge and experience people have. This means that the manual is not necessarily as good as it would be if a wizard had been paid handsomely to write it and had spent millennia to perfect it. Be warned.
