How to run xfce-terminal with different commands per tab and keep using the tabs after the commands have returned?
To keep the overview I like to place multiple commands always in the same order and start them automatically together (gradle, git, database, scala-REPL, jboss…)
What does a dot after the file permission bits mean?
I performed an ls -la on directory on my CentOS 6.4 server here and the permissions for a given file came out as:

Does Linux perform “opportunistic swapping”, or is it a myth?
Suppose a program asks for some memory, but there is not enough free memory left. There are several different ways Linux could respond. One response is to select some other used memory, which has not been accessed recently, and move this inactive memory to swap.
Determining cause of Linux kernel panic
I’m running an Ubuntu 12.04 derivative (amd64) and I’ve been having really strange issues recently. Out of the blue, seemingly, X will freeze completely for a while (1-3 minutes?) and then the system will reboot. This system is overclocked, but very stable as verified in Windows, which leads me to believe I’m having a kernel panic or an issue with one of my modules. Even in Linux, I can run LINPACK and won’t see a crash despite putting ridiculous load on the CPU. Crashes seem to happen at random times, even when the machine is sitting idle.
How important is it that $TERM is correct?
I recently switched from rxvt-unicode to st. This means I went from $TERM=rxvt-unicode-256color to $TERM=st-256color.
