comment How does ssh -X function?
@Alexios I remember the old Sun 3 series. We had a room full of Sun X terminals (diskless) running off a single server for our computer lab. Quite fun when the power flickered and all 20 or so X Terms tried to boot at the same time. The main problem was that Sun's vision exceeded what the technology could support at the time.

comment Execute remote commands, completely detaching from the ssh connection
You might need to redirect stdin to /dev/null on the remote system. That may be why ssh isn't exiting.

comment How sudo/root-ness detection works
@Mehrdad - Most systems allow you to specify a uid when adding a new user. Just specify uid 0, and you have another root user.

comment Standard and/or common directories on Unix/Linux OSes
Another thing to keep in mind about Unix is the concept that "everything is a file" (or at least looks like one). For example, the stuff in /proc looks like files and directories, but the contents are really created dynamically by the kernel when you access them. This means that you can use the same tools (ls, cat, etc.) to access this information.

comment How to install/default to the command line version of Emacs?
Additionally, if the $DISPLAY environment variable is not set, emacs will use the terminal version.

comment Does optimizing for size reduce runtime memory usage as well as binary size?
Not necessarily. It may just be doing aligned versus unaligned reads at the assembly level. I was thinking of the case where instead of padding an array of structures so that each element is aligned, they are arranged without padding.
