November 22, 2006 Show
We discussed Black Friday websites that list the store sales for the Friday after Thanksgiving well ahead of time. Best Buy didn't appreciate the publicity and made one of the web sites remove their ads. See bfads.net and dealspl.us/Black-Friday
Michael likes a free alarm clock program called Kirby
Alarm. Compared to Microsoft's Outlook: Kirby is free, Outlook is not,
Kirby minimizes to the system tray, Outlook does not, Kirby runs on all
versions of Windows, the latest versions of Outlook do not, Kirby is a simple
small program, Outlook is a complex and big program, Outlook is only useful on
one computer, Kirby is portable - you can copy it to a thumb drive and take it
with you. Then plug the thumb drive into any Windows computer and run
Joe took a first look at Cyberdefender.com which just came out with a free package of a firewall, anti-virus, anti-spam and anti-Spyware. It provides updates however using a peer to peer system which is unusual for this sort of program. The jury is still out.
Windows Vista will have the "Windows Genuine Advantage" built in. This is a feature for Microsoft's advantage, it detects pirated versions of Windows.
The Internet Society of New York will have their monthly meeting Thursday, December 21, 2006. See isoc-ny.org
We are pre-empted next week.

More coming . . .
Next week, we'll talk a bit about Black Friday websites where you can learn ahead of time about Thanksgiving sales.
November 8, 2006 Show
Microsoft and Novell entered into an agreement to make Novell's Suse Linux
Operating System work better with Windows. Why? We're not sure.
We discussed stealing WiFi Internet access. Is it OK? Who does it hurt? 23%
of WiFi networks have no security.

We thank everyone that pledged money to WBAI during the recent fund raising drive. Making up for last weeks pre-emption, we covered a lot of short topics. Among them was more on virtual machine software. Should you buy a new Windows XP PC at the end of 2006 or wait for Vista? Alfred, Michael and Hank said to buy now.
A caller asked about researching computer terminology. Joe mentioned that in Google you can learn the meaning of word by searching for "define:someword". He also suggested www.wikipedia.org.
More on Virtual Machine software
There are three vendors of virtual machine software for PCs: VMware, Microsoft and Parallels. On September 14, 2006, Steve Gibson did a Podcast that compared Virtual PC from Microsoft vs. VMware workstation from VMware.
Currently the only VM software for Mac users is from Parallels. Virtual PC used to run on Macs, but then Microsoft purchased the product. VMware has a Mac product in beta test.
Virtual PC 2004
VMware Workstation v5
WMware offers many pre-built Linux virtual machines that you can download and use for free. Vedors use them as a great way to demonstrate products. The one that gets the most attention is the "browser appliance". It's a copy of Linux with Firefox and not much else. Browsing the Internet with this copy of Firefox is about as safe as safe gets.
VMware and Virtual PC also come in server versions. VMware Server is free and can create VMs (and run VMs created in VPC). However, it does not support either USB or sound. It only supports server versions of Windows for a host OS. Likewise, Virtual PC Server 2005 does not support sound or USB.
Downside to virtual machines
Creating virtual machines used to be very hard. For a long time VMware was the only company to offer it for Windows and Connectix was the only company offering it on a Macintosh. The most recent processors however include new hardware specifically designed for use with virtual machines. This extra hardware makes writing VM software easier, and thus we can expect more products in the future.
In addition, hardware assisted virtual machines will run faster than those that are now fully created with software.
VMware, the market leader in virtual machines has many high end products that are not targeted to PCs. Their first step up from VMware workstation and Server is a product called ESX Server. The big change with ESX server is that it doesn't need Windows. That is, it installs on a new computer (bare metal to us nerds) and it is the operating system running on that machine. All copies of Windows and Linux on an ESX server machine are virtual. When the real power button is turned on, the ESX server software runs. It, in turn, runs your VMs.
ESX server is very expensive ($1,000 for 2 cpus) and can't even be
purchased stand-alone. It's only sold with a suite of other high end software
