From time to time, I love to continuously surf the web pages without interruption at home and at office. So one of my most favorite extensions is SessionSaver .2. Finally, this feature has been included into Firefox 2.0.

My printer at office is HP LaserJet 3055 and I have already added to Ubuntu Dapper for so long. It worked just well. Today I would like to print the first page after upgraded to Edgy. The result page is incorrect since it only printed the cropped page. Note that I printed a pdf through evince. I guessed that the problem should be incorrect driver due to upgrading last night so I just simply removed it and added a new one. Unfortunately, I was unable to add a new printer anymore. So I started gnome-cups-add on a shell prompt. Below is what I get.

** (gnome-cups-add:17835): WARNING **: IPP request failed with status 1280

I have just upgraded my laptop to Ubuntu Edgy Eft after waiting for so long. After the upgrade, I was unable to start VMware Player because of missing some libraries. The symptom was that the VMware process consumed 100% utilization and I had to kill it manually. There are several threads talking about this issue, e.g., Ubuntu Forums.

I decided to upgrade my laptop to Ubuntu Edgy Eft early to see what it is yesterday. At first, I downloaded a desktop disc for off-line upgrade. Sadly, I did the wrong thing. After inserted the cdrom disc, I got a dialog box indicated that we were going to upgrade distribution. However, I preferred to upgrade in text mode so I cancelled it immediately. That was just a problem.

I'm going to upgrade my laptop from Dapper to Edgy very soon. One common procedure is to upgrade all packages to the latest versions before upgrading the whole distribution. Then I found something weird because I usually used graphical tools to upgrade packages but now I run apt-get as follow.

sudo apt-get update
sudo apt-get upgrade

I found a proof of concept of green power at EcoGeek. It's all about making a cluster with processing power of 22.7 GHz using 30A power from vegetable-oil-powered generator.
