It has come to my attention that my newly released NetBeans Book is now available through Amazon.

Java EE 5 Development With NetBeans 6

It is also available directly from Packt Publishing.

I just finished installing Ubuntu Intrepid Ibex on my HP Pavilion dv6810us, which is part of the HP dv6000 series

Installation was fairly straightforward, the only hiccup I found was that wireless networking was not working out of the box, I had to install ndiswrapper, but thankfully this was pretty painless. All I had to do was install ndisgtk

sudo apt-get install ndisgtk

And the Windows XP drivers for its wireless card (identified as 03:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) by lspci According to this post in the Ubuntu forums, the correct drivers can be found here.

Once I installed ndisgtk and downloaded the windows drivers, all I had to do was point ndisgtk to the .inf file included with the driver, and wireless "just worked", no mucking around with blacklisting drivers or anything like I had to do with previous versions of Ubuntu

I also ran into an issue in which the system would stop booting unless a key (any key) was pressed repeatedly. This issue seems to be affecting several Hewlett Packard (HP) and Compaq laptops.

This issue was reported on launchpad, and I found a workaround there.

The file /boot/grub/menu.lst needs to be edited as root, I use vi as my editor, substitute the following command with your favorite editor:

vi /boot/grub/menu.list

Find the following line:

kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=c877e76e-7e7f-4b47-aec7-6ae28d1ab767 ro quiet splash

and append "acpi=noirq" to it. After doing this the line should look like this:

kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=c877e76e-7e7f-4b47-aec7-6ae28d1ab767 ro quiet splash acpi=noirq

After making the above modifications I was able to boot to Ubuntu Intrepid Ibex normally.
