comment In Linux, is working as su the same as working as root?
I also read that BSDs have wheel, but again I haven't used BSD in quite a while, so I don't remember. Here's an article discussing that: administratosphere.wordpress.com/2007/07/19/the-wheel-group Here it's said that OS X had wheel at one time osxfaq.com/Tutorials/LearningCenter/AdvancedUnix/ugp/index.ws Here's an article about wheel in FreeBSD freebsd.org/doc/en/books/handbook/securing-freebsd.html In the end, it's good to keep wheel in mind even if the system doesn't support it. You'll never know when you'll stumble upon a system with configured wheel.

I honestly don't know. I think that in Solaris it does, but I can't test it at the moment. I remember I read that back when GNU su was new, rms decided not to use wheel because of ideological reasons. I assume that at the time Unix systems regularly checked to see if user was in wheel. Also I read somewhere that Solaris will use wheel if group exists. Here's a source for that windowsecurity.com/whitepapers/Armoring_Solaris.html

+1 for switch user. Not many people remember that it can be used for any username if you're in wheel.

comment What kind of chip to use for underwater robotics?
Simpler controllers seem like a good way to solve this problem, but you can't run GNU/Linux on them. +1 for tethering and Mars reference!

comment What kind of chip to use for underwater robotics?
This is going to be harsh but, no way you can do this with $100. If you had embedded systems experience and not needed development hardware, you could maybe do it. If you do decide to go with it, ARM looks like a good place to start. There are powerful chips available which could control hardware with no major problems. Internal temperature is the easiest part of the whole process. Also, expect GPS to be at least $50 if you are going top build module yourself.Try looking for ARM development systems and check out their prices. If they are too expensive, try designing the rest of the robot first

comment Why hasn't micro-USB replaced all others?
@Narcolapser Well, yes and no. Cables with higher diameter would be better. On the other hand USB uses two data cables using differential signaling. That means that cables should be close together in order to minimize noise. Also standard cables can be used with micro connectors. @Jay Bazuzi I read somewhere that mini is considered deprecated, so that's a plus for micro. You are right about accessibility.

comment What does an arrow (“->”) symbol mean on the command line?
Actually, OS X is Unix. GNU/Linux is a very similar but not directly related operating system.

@Spiff Never seen such a product before. Thanks for enlightening me!
