There seems to be a bug in Ubuntu in that when you reboot the system all remote CUPS printer connections are forgotten. This sounded like something needing a bit of scripting magic, so I went searching for how to accomplish that. Turns out it was quite simple actually. The utility lpadmin will be your friend to command line administer printers / print queues. The first lpadmin command attaches to the CUPS shared network printer queue via the IPP protocol, and the second lpadmin command sets the printer as the system default.
Recently I ran into a situation where a Perl CPAN module I needed was not available in the Ubuntu repositories. Someone on IRC kindly showed me a slick Ubuntu package which is able to quickly produce Ubuntu .deb packages out of Perl CPAN modules! Here is what you need to know:
Using a developer computer (aka "play box") add the following packages:
Next use dh-make-perl to package the needed CPAN module:
Today's blog post explains how to get this very useful component of the TinyDNS project to work with Ubuntu Server. You may fetch down the Michael Stella's original version of his code, and then note my adjustments to get it to work on the Ubuntu Server (9.04 through 10.04).

Unpack the file, then make the following adjustments:
Patching up djb_update.pl
# Domain name
-my $domain_name = "MYDOMAIN";
When I first went looking for HOW-TO docs concerning installing Daniel J. Bernstein's djbdns on Ubuntu, I could not find such. What I did find was plenty of docs on how to download and compile Mr. Bernstein's djbdns code from source, however Ubuntu has very kindly created packages of everything you need for installing djbdns.
I offered a presentation at the 2010 ICCM conference about replacing a couple of servers during this past year. The arrived at configuration was very much a middle point between a normal server configuration at one end and a firmware / USB HDD server at the other end of the spectrum. I was able to deliver a very compact configuration that has low power consumption, yet runs standard Ubuntu Server Linux and has a 3ware RAID card to facilitate drive mirroring.
When my previous display started getting fuzzy, I plugged in another display and got a much clearer view until I rebooted. After the reboot, the display came up as 1280 x 1024 resolution instead of my usual 1600 x 1200. I went searching and found references to capturing the EDID from the display and correcting the EDID information. Using the Nvidia X Server Settings applet I captured the EDID, but the Phoenix editor was unable to open the file.
Ubuntu 9.10 ships missing my favorite theme, Clearlooks. This may simply be corrected by adding the package "gnome-themes" which is where that theme resides.
Ubuntu 9.10 ships with far less screen savers installed by default. Notably my favorite was missing, Skyrocket. This may simply be corrected by adding the package "rss-glx" which is where that screen saver resides.
