One of the most frustrating things about a fresh install of Ubuntu is that when it asks you to set your keyring password, it warns you of security issues. And when you set your password, it asks for it every time someone wants to connect to the secured wireless.
To get past this, try the following:
- Right-click on your Network Manager applet in the upper right corner and select “Edit Connections”.
- Click on the Wireless Tab, select your wireless network, and click “Edit”.
- At the bottom on the following window put a check in the “Available to all users” box.
- Close all windows and reboot.
This makes the wireless available without entering the keyring password.

Tim and I are always arguing about batteries in our laptops.
He says that you can use and use your battery without accelerating it’s degradation and that keeping a lithium-ion battery fully charged is constantly exposing it to one of its greatest enemies: heat. I say that it’s best to keep it fully charged — that the battery’s enemy is exhaustion of life-cycles. I had once read that the average lithium-ion battery has a life expectancy of 300 cycles. If you cycle it daily, it will die in under a year.
This chart gives good information:
www.batteryuniversity.com/partone-21.htm
So the chart says Tim is right–you can use and use your lithium-ion battery. Heat and deep discharges are the enemy.
It still puzzles me that he’s been through two batteries in four years at school and in the four years I’ve had this PC, I’ve only been through one. My guess is that it’s because of the deep discharges his experienced while sitting in the dorm lobby watching football.
So — the bottom line: Use your battery in your laptop, but don’t deeply discharge it needlessly.

This week, HP bought Palm.
What does that mean?
- It means HP wants to be a contender in the smartphone market.
- It means HP doesn’t want to be a slave to Microsoft.
- It means HP isn’t smitten by Windows Mobile 7.
- It means HP doesn’t think that the iPhone and Android phones have that market sewn up.
It means options for the consumer.
