Email from Peggy: Dear Dr Shurtz, I got a copy of the report JP Morgan’s Nothing But Net. Can you tell me what is the best investment vehicle for an individual investor to get into to participate in this expected healthy return for 2008? I realize you are not a financial advisor, just hoping you would share with me the investment firm or name of the Mutual Fund you are using to participate in the IT/Internet ‘rewards.
Tech Talk Answers: Thanks for listening. I can’t really help with this request. Tech stocks are hard to predict. The one theme in JP Morgan’s report was Internet stock that can cash in on the growing advertising and e-commerce markets. They have solid cash flows and are not speculative ideas with real income potential. This gives me so good ideas for future shows. I will try to identify emerging technologies and companies that are worth watching.
Profiles in IT: Gottfried Wilhelm Leibnitz
Gottfried Wilhelm Leibniz developed binary arithmetic. The root is from the Latin word binarius which literally meant "two by two."
He was born in 1746 and died in 1716.
He contributed to law, history, theology, politics, engineering, geology, physics, and perhaps most importantly, philosophy, mathematics and logic.
The Leibniz began to teach himself Latin at the age of 8, and Greek a few years later.
His study of logic and intellectual quest for order continued throughout his life.
At the age of 20 he published Dissertation on the Art of Combinatorics in which he sought a a universal symbolic language and reduce all debate to calculation.
During this time in Paris, he became acquainted with several of the leading philosophers, read the unpublished manuscripts of Blaise Pascal and Rene Descartes.
He met Christiaan Huygens from whom he learned mathematics. He then laid the foundation of calculus, which become his philosophical legacy. The invention of the differential and integral calculus is part of his search for a universal language. A dispute with Issac Newton over the invention of calculus scandalized his life.
In 1703 he published An Explanation of Binary Arithmetic Using only the Characters 0 and 1. He was still seeking a universal symbolic language.
Of binary numeration, he writes it permits new discoveries [in] . . . arithmetic . . . in geometry, because when the numbers are reduced to the simplest principles, like 0 and 1, a wonderful order appears everywhere.
With base 2 numeration, Leibniz witnessed the confluence of several intellectual ideas of his world view, not just the characteristica generalis, but also theological and mystical ideas of order, harmony and creation, with 0 denoting nothing and 1 denoting God.
His 1703 paper contains the application of binary numbers to the ancient Chinese text of Yijing (I-Ching or Book of Changes).
This he thought, might be the origin of a universal symbolic language.
The ancient Chinese lineations or 64 hexagrams of Yijing consist of six lines atop one another, each of which is either solid or broken, forming a total of 64 possibilities. A grouping of three such lines is called a trigram.
A solid line can be viewed as one and a broken line as zero.
Leibniz cites an application to weighing masses. Suppose that a two-pan balance is used for weighing stones. Leibniz claims that all stones of integral weight between 1 and 15 inclusive can be weighed with just four standard weights.
Leibniz’ designed stepped wheel calculator was built for decimal numbers. He gave some thought over the years to another machine which would incorporate his beloved binary system using on/off principles.
125 years later, a binary logic system based on true and false conditionals was developed in mid-19th century by George Boole
John von Neumann pressed for the use of binary arithmetic in 1946 in the ENIAC computer and the rest is history.
Conference focused on: Audio, digital imaging, emerging technology, gaming, high performance audio and home theater, home networking, in-vehicle technology, and wireless.
Auto technology was a spotlighted ? car-to-car communication, GPS, onboard computer, video sensors to eliminate blind spots, auto-braking feedback.
Emerging technologies included robotics, biometrics, voice recognition devices, disposable technology, new audio media, nanotechnologies, and flexible computing devices.
Gates Give CES Keynote and Acknowledges the Cloud
Gates lauded how computers and the internet have become ubiquitous and predicted the coming ten years would deliver even greater technology changes.
He noted that there are more than a billion personal computers in use in the world and more than 40 per cent of people on the planet have mobile telephones.
The next decade will be more focused on connecting people.
Gates admitted that the market was moving away from Microsoft’s core money-maker, packaged software that people install on their own machines.
He said that applications will run on the internet, in the cloud as we say, and use the best of software services.
Gates said high-definition video experiences would be everywhere, from televisions to wall projections and even built into desks or tables.
People will roam in increasingly in three-dimensional virtual worlds, tending to business, shopping and other aspects of daily life.
The consumer will take getting data for granted.
While the first digital decade was marked by the keyboard and the computer mouse, the new decade would be marked by "natural user interfaces" such as touch screens and gesture controls,? according to Gates.
Mr Gates has spoken 11 times at annual CES events. This will be his last as a full-time Microsoft employee.
Warner Backs Blue Ray
Warner Brothers had drop HD DVD support and will now Blu-ray discs exclusively.
The fight is a replay of the VHS versus Betamax battle of the 1980s.
This time, however, the Sony product appears to have prevailed.
With Warner on board, Blu-ray now has about 70 percent of the market locked up.
Walt Disney, 20th Century Fox, MGM, Lionsgate and, of course, Sony are all on Blu-ray’s team.
HD DVD, however, is not dead. Two major studios, Paramount Pictures and Universal Pictures, have deals in place to continue releasing their movies exclusively on HD DVD, as does DreamWorks Animation.
Consumers have been largely sitting on the sidelines, waiting to buy high-definition players until they see which will have the most titles available.
Retailers have been complaining about having to devote space to three kinds of DVDs. And the movie business has delayed tapping a lucrative new market worth billions. High-definition discs sell for a 25 percent premium.
HD DVD players have been much cheaper than Blu-ray machines, but Blu-ray discs have more storage space and more advanced protections against piracy. Both versions deliver sharp resolution.
Blu-ray players can now be purchased for under $300. HD DVD players cost around $100.

Nmap (Network Mapper)
A free open source utility for network exploration or security auditing.
It was designed to rapidly scan large networks, although it works fine against single hosts.
Nmap determines what hosts are available on the network, what services those hosts are offering, what operating systems they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.
