Prevent Ubuntu from asking a password after resuming from Hibernate or Suspend

T4L — Tue, 06 Sep 2011 20:19:43 +0000

When you close the lid of your laptop and Ubuntu is running, the computer goes into Suspend mode. Same goes for chosing Hibernate from the shutdown menu, when the laptop goes into deep sleep and consumes less power. When resuming from these two states, Ubuntu will ask you for your password. If you’d like to get rid of this password field, you need to launch gconf-editor and navigate to apps > gnome-power-manager > lock. There you’ll find a checkbox for hibernate and one for suspend. Uncheck these and close the Configuration Editor. Next time you resume from Suspend and Hibernate, you won’t be prompted for a password.
You can still manually lock your screen before closing the lid by using Ctrl+Alt+L.

Impress your friends with your CLI magic in Linux

T4L — Mon, 07 Feb 2011 23:16:00 +0000

Here are two one-liners to have fun with. The first one takes a block of text you input it and displays it one character at a time, creating the impression that someone else is typing:

echo “I have a troll in my Linux box that is doing all the work for me” | pv -qL 10

The second one creates a poor, Matrix-like effect in your Teminal:

tr -c “[:digit:]” ” ” < /dev/urandom | dd cbs=$COLUMNS conv=unblock | GREP_COLOR=”1;32″ grep --color “[^ ]“

Have fun.

Monitor your changed files in real-time in Linux

T4L — Mon, 24 Jan 2011 23:16:00 +0000

Everybody knows top or htop. Ever wished there was something similar but to monitor your files instead of CPU usage and processes? Well, there is.
Run this:

watch -d -n 2 ‘df; ls -FlAt;’

and you’ll get to spy on which files are getting written on your system. Every time a file gets modified it will get highlighted for a second or so. The above command is useful when you grant someone SSH access to your box and wish to know exactly what they’re modifying.
