From Linux.com :: File compression tools for Linux:

Use

tar zxvf archived.tar.gz

to extract all the files from a gzip-compressed tarbal

Better: make "untar" alias"

Fix Printer Margins

Modified: 2007-03-13 12:06:43

From http://www.nerdylorrin.net/wiki/Wiki.jsp?page=CUPS

Configuring the Margins

Run the following commands:

cd /tmp
wget http://www.linuxprinting.org/download/printing/alignmargins
wget http://www.linuxprinting.org/download/printing/align.ps
chmod 755 alignmargins
su
./alignmargins

This will print an alignment page. Text at the top of the page should indicate the currently set Margins and HWMargins. If these aren't all set to 0, enter 0 at every prompt and start over.

The first task is to align the output within the physical page. Measure H and V (in inches) from the edge of the page and calculate x and y as explained on the print out. Enter 0 for all the m* values and the calculated x and y values. 

Actually just experiment with changing the x and y values. I had to do 0 for x and -45 for y. Keep setting the m values to 0. I don't know what they are for.

Irssi: how to keep Private messages from disappearing in other windows

Modified: 2007-08-10 10:30:22

I think the important ones are:

• use_status_window = "no";
• use_msgs_window = "no";

Have something like this in ~/.irssi/config

settings = {
 core = {
   real_name = "Elijah Lofgren";
   user_name = "elijahlofgren";
   nick = "elijahlofgren";
 };
 "fe-common/core" = {
   autocreate_own_query = "no";
   autocreate_query_level = "NONE";
   use_status_window = "no";
   use_msgs_window = "no";
   autoclose_windows = "no";
   reuse_unused_windows = "yes";
   windows_auto_renumber = "no";
   print_active_channel = "yes";
   theme = "elho";
   beep_msg_level = "msgs";
   window_auto_change = "yes";
   autocreate_split_windows = "yes";
 };
};
