Fixing a stalling HP USB printer in Ubuntu 10.04

I had struggled with a very frustrating problem when printing to my USB HP Deskjet printer using Ubuntu. The printer would sometimes print an entire job then refuse to print any more after that. The documents would show in the queue but you could not cancel or release them. 
 
Another symptom of the problem would be tasks on the machine, owned by a user lp, that you could not kill. These were USB print jobs that also caused a high load average although the machine performance was not affected. These conditions would sometimes persist between reboots.

Trouble with AMD Cool and Quiet

I've had an ongoing problem with my computer ever since I purchased it in 2008. Every once in a while, mostly under high load, the computer would freeze. I couldn't find anything in the logs regarding the lock up, and the problem persisted through multiple versions of Ubuntu, so I assumed it was a hardware and not a software problem.

The processor is an AMD Phenom 9850 and the motherboard an Asus M3N-HD HDMI.

I have been compiling the Chromium OS image, or trying to, for the last few weeks. I have been successful a few times, but nearly every time the machine would freeze.

Just thought I'd mention the Hewlett Packard dv4150us works perfectly with Ubuntu 10.04.

Ubuntu Linux behind the making of Avatar

Weta Digital, co-founded by Peter Jackson, is a digital visual effects company that worked on the flora and fauna of Pandora in the wildly popular movie Avatar.

Jordanopensource.org is reporting Ubuntu Linux is the core OS that runs on their massive 4,000 server, 40,000 CPU farm, one of the most powerful in the world. Imagine the cost savings on licensing alone.

Ubuntu 9.10 released

Ubuntu 9.10 has been released. Attached are the torrent files as the mirrors are busy as usual. There are many improvements to both Ubuntu and Kubuntu. Help the community out and seed these torrents please.

SQL Server using Linux: SQuirrel SQL Client

A big part of my job is using SQL server and having the necessary tools to interface with SQL server is a must. One of the only tools I have found for using SQL server on the Linux platform is SQuirrel SQL Client.

Groupwise 8 and Linux

Installing the GroupWise 8 client on Ubuntu Linux 64 bit works great using these instructions. Did I mention that the GroupWise 8 Linux client has Notify built in..and it works? =)

Restarting the sound system in Ubuntu

There is a really annoying bug that crops up sometimes in which you will get an error message similar to "xine was unable to initialize any audio drivers" or in KDE 4.2 "The audio playback device HDA Intel (AD198x Analog) does not work. Falling back to ."

To fix this, I would normally reboot, but I found a page that specified how to restart the sound system. The instructions, unfortunately did not work for me, and I could not post a follow up.

First run:

$ lsof | grep pcm
