Spam
Tracking doesn't work. Tracking is tracking down people who have written virus programs or who issue spam emails. Someone just got nine years for an email scam. That is the exception. I don't think it is a deterrent because the money is still there. It is the same as illegal drugs. If the money disappears the crime will dry up.
Filters don't work. For every filter you try to implement, the spammers have seven ways around it. I've heard one of the spam filters grabs emails that don't have any real words in the subject.
Now, you can get infected with a virus from clicking on a URL in an email. It used to be, you had to open an attachment. I've noticed the nasty trend of these virus writers getting smarter and sneakier. There is more than bragging rights involved these days. Computer virus are big business. They make money by sticking spyware on your computer or taking over the operating system to infect other computers. The way spyware makes money is by tracking your movements and selling your habits to advertisers or by using the data collected to steel from you or your company.
I've only found one filter that seems to work.I use Gmail and there is a community of people out there marking email as spam. As a bunch of people mark the email as spam, Gmail starts pulling the emails into people's spam folders.

Theory of Everything
If I'm at the origin, and the furthest known (known: piece of knowledge of any sort) is at point 1. Then is there anything at point 2? The moment you know something is at point 2, it becomes point 1.
Will there always be something at point 2? Was there always something at point 2?
String Theory: More complex bullshit spouted by physicists who really won't admit they have no idea what is going on at the sub atomic level. Basically, String Theory says once you delve below protons, electrons, and  neutrons, you run smack into all of these little funny subatomic particles that have been given all kinds of cool names like B1 and B2 ... Those particles are actually gas-zillions of these tinny vibrating strings. The strings aren't made of anything. They just "are". Actually, they are little bits of torn reality or poly-dimensional-intersections. Some say for Strings to exist, there must be 6 hidden dimensions, or was it 29, or was it an infinite number? The strings don't really exist themselves. They are manifestations. Perhaps they are just the overlap of these many dimensions. The strings change shape or rate of vibration and they, in tandem, become different forms of matter or energy. As they change shape or rate of vibration, they give off electromagnetic energy, or the emit gravity, or the strong or weak force.
This all boils down to the simple fact that science cannot tell us what gravity is. It drives scientists nuts. It makes me laugh. We cannot say what holds us down. What holds the planet and sun together in a dance through the galaxy. That is the target of all of this. I wonder if I'll know in my lifetime. If you have ever dropped a bolling ball on your toe, you know about as much about gravity as any of the smartest people on Earth. Well, OK, knowing more would probably not help your game.

Media Player
I'm in the market for a new MP3 player. The trouble is, they do more than play music now. Some of them play videos. Most of them act like hard drives. It is a bad time to want one of these things. Next week some one will come out with the all in one doo-hickey that is a phone, plays music and videos, plays radio and TV, receives satellite TV and radio, acts like a palm device, has GPS, and lets you really surf the Internet for $39.95. I just know this is going to happen to me. I can feel it. Someone please tell me which one to get.

Office
some one commented on the MS Office post below. They recommend Word Perfect Office. I'm not so sure. At home, I use Open Office. It is free and works extremely well. I haven't upgraded in a long time. There is another called EZ Office. It is designed for Windows only. It appears to have gone from the scene. Star Office is basically Open Office. Sun has donated allot to the project. To each their own, but MS Office sucks.
