Linux
I got Kubuntu installed in an attempt to program some Bluetooth apps in Linux. I hate it. One of the problems is a linux issue. Apparently, they can provide enough of a driver for my wireless card that it knows it is there, but not enough to actually use the card. After finding a method of using the windows driver, I finally got the card working, but now the KNetworkManager isn't working properly. With this and other issues I have with the OS, I am going to switch to Debian, the Linux OS I used to have on my computer, and the Linux lab used to use. It may still have wireless issues, but I'm pretty sure it will solve the other issues.

Bluetooth
I recently purchased on book on Bluetooth programming from Amazon.com, Bluetooth Essentials for Programmers, and have succeed in making an application that can search for Bluetooth devices nearby, create a server, and create a client to connect to the server and send a message. This application uses the Microsoft Bluetooth stack, which is quite limited in its API. For the purposes of the class project and possibly ease of use, I will be temporarily programming for the Linux environment using the BlueZ stack, as well as programming for the Widcomm/Broadcomm stack in Windows. I think the Widcomm stack will still allow a reasonable level of compatibility as it is a stack installed by Windows automatically when I connect a Bluetooth adapter to the computer. Both of these APIs cover RFCOMM, L2CAP, SCO, and HCI protocols, whereas the Microsoft Stack API only allows for the RFCOMM protocol, which is an odd choice in my opinion. The L2CAP protocol encompasses the RFCOMM protocol, so I would think the L2CAP would make more since.

For this one, addresses 1 - 5 have Amsterdam listings, but 6 is an Arizona listing
and 7 is back in Amsterdam. This is because although 6 is most likely in Amsterdam,
it is owned by a Tier 1 ISP, Global Crossing, which has a business address in Arizona.
The next IP address is listed again in Amsterdam. At 9, the ISP switches over to Sprint,
another Tier 1 ISP, until 14, which is a NAP. Finally, at 17, I reached Millersville.
