comment Check for existence of files prior to acting on them
Be careful: there's an entire class of bugs that can happen if you have time interval between check and use: en.wikipedia.org/wiki/Time_of_check_to_time_of_use These bugs can be particularly hard to ferret out, as the code certainly looks correct.

comment Why does linux-based laptops have weak wifi signal in comparison to windows-based laptop?
I'veseen this a few times, too. My suspicion is that either (a) Windows isn't telling the truth, (b) the driver isn't telling Windows the truth (c) the Windows driver takes advantage of the wireless hardware better than the Linux driver.

comment Do I need a special firewall on a personal computer
I'm not sure I see the need for one, given that all distros include tools like netstat, where you can see exactly what TCP, UDP, etc ports are open and their status, and also where you can explicitly control known daemon processes. As near as I can tell, Windows users have firewalls because Windows 95 and early NT did not have the tools, or the documentation on what was listening, for folks to feel comfortable putting them on arbitrary networks.
