comment Is it possible to run vlc as root?
If you actually did install vlc that way ... have you just tried running vlc as root? Why doesn't it work? What does happen when you try? What did you expect to go differently?

comment Remote Xfce session in a separate console?
@Vasilly.Prokopyev: oh ... that's what you meant. Well, when setting up the ssh connection, you can add -L177:127.0.01:177 and -R6001:127.0.0.1:6001 to the ssh call, to make this work over SSH. However, in that scenario you could just install x2goserver on your desktop pc and x2goclient on your netbook. I do believe the client can be full screen.

comment Why is ping much faster when using -f
I don't understand this answer. ryekayo's average rtt is higher when using the -f option. So 1. the OP's claim can't be reproduced, 2. the excerpts from the man page don't give the slightest hint at which measurement is more accurate and 3. what's a "fair" result anyways?

comment Use bash's read builtin without a while loop
My problem was that I thought bash would put everything between the pipe symbol and the end of the line into the same subshell, but apparently it only reads the next statement.

comment Use bash's read builtin without a while loop
I think I got it: The actual point is that WHEN USING PIPES, bash creates subshells for each processes of the pipeline, and due to scoping the variables are gone, after the pipeline. Using {} makes the remainder of the line an (one!) element of the pipeline, while inside that subshell the variables are available. Using process substitution one is not using pipes and therefore bash does not spawn subshells.

comment Use bash's read builtin without a while loop
{} ... I only tried (). Why does the ; in your second example not start "a new set of commands"? Actually I don't understand the < < construct at all. Need to think ...
