It was not so long ago that the Intel 80386 was the most power space-qualified microprocessor. Now, NASA and
private companies are experimenting with commercial-off-the-shelf (COTS) components for small, inexpensive
satellites. Contrary to mainstream media opinion, however, NASA is not just wasting money on current projects;
space is an extremely hostile environment and so is the process of getting there. In a year's time, gazillions
of different subatomic particles and micrometeorites bombard everything. G-forces and vibration during launch
are immense. iPhone 4 antenna problems are trivial compared to cosmic rays flipping bits and a 0.1 micron chunk
of un-accreted planet matter striking at 20 kmph. Still, necessity is the mother of invention, so I have no
doubt that eventually solutions will be found. "A journey of 1000 miles begins with the first step," say the

Human RFID - Coming to
an Appendage Near You
(source: Fox News)
of Mexico has surgically implanted RFID chips, the size of a grain of rice, in the upper arms of staff at the
attorney general’s office in Mexico City. When read by scanners at the entrance, they allow or deny access to a
secure building, hoping to prevent trespassing by vengeful drug lords. Amal Graafstra's hands, pictured here,
contain self-inflicted RFID capsules. Techno-futurists like Amal embrace the technology as a means of staying
connected with society and government; techno-phobes shun it as a means of staying connected with society and
government. It is an excellent way to keep the CIA from offing you in a case of mistaken identity, but if you're

Marine Radio Historical Society Needs Help
(no $ / £ / ¥ / € involved)
Is that a cool banner or what? It belongs to the Marine Radio Historical Society (MRHS), which per their
website, "is a small group of dedicated individuals who share the goals of documenting, preserving and restoring
the artifacts of maritime radio history. Our area of specialization is the coast stations, ships and companies
of the west coast of the United States. But anything to do with maritime radio anywhere in the world is of
interest to us. Our projects are aimed at the restoration and actual operation of historic artifacts ."

2010 Techie Billionaires(source:
Forbes recently released its 2010 list of the world's billionaires. It appears once again that the evil
capitalist systems served some communist societies as handily as it did representative republics
(one of those groups claims to despise capitalism)
. Of the 1112
billionaires, 16 are new arrivals. #1 is telecom magnate Carlos Helú of Mexico
(home country of our illegal population)
. Fortunes were made on everything from concrete to high finance.
Much is inherited wealth. Here are some of the other notable top techie billionaires.
|USA & Canada: 527 total
|Bill Gates, Steve Ballmer & Paul Allen (all MS), James Balsillie, Mike Lazaridis & Doug Fregin (all
RIM), the Google twins, Gordon Moore (of Moore's Law - yep, billionaire), Ray Dolby (of stereo fame), Henry
Samueli (Broadcom - stock option fraud), Steve Jobs (Apple)
|Asia-Pacific: 234 total
|Lee Kun-Hee (Samsung), Ming-Kai Tsai (MediaTek)
|Europe & Russia: 248 total
|Vladimir Yevtsushenkov (Russia), Denis O'Brien (Ireland), John Caudwell (UK)
|Middle East: 65 total
|Ahmet Nazif Zorlu (Turkey)
|Latin America: 23 total

Money in Mathematics(source:
Time was that having a job that exploited a degree mathematics was about as profitable as a degree in
renaissance poetry. Not anymore. As evidenced by the huge successes of the creators of Google's PageRank system,
stock market analysis algorithms, electronic device modeling, and consumer behavioral patterns, in assessing and
then modifying human behavior, there are enormous monetary rewards to be had for the right mathematical skills.
Information theory is at the root of much of the realm, including the ability to precisely model semiconductors.
The often crippling expense of not achieving first-pass success on a major IC design is proof of the critical
need for the capability. Quite often the people developing the math behind those engines are mathematicians and
physicists, not engineers. 6-17-2010
probably comes as no surprise that the greatest concentration of graduate degrees in the U.S. are in the
northeast and in the Silicon Valley areas. #1 is the D.C. metropolitan region with 22% having graduate degrees
(lawyers, not engineers)
. Bridgeport, CT, Santa Clara, CA, and Boston, MA run a close 2nd, 3rd and 4th at
about 19%. Not coincidentally, salary levels tend to be highest in those areas as well.
you then view the proportions with a HS diploma or above, Silicon Valley drops precipitously, while the NE gets
even darker blue. All of California gets suddenly light blue. Any theories on that? I've got my own. It is
perplexing that the U.S. Dept. of Labor just announced that
retraining is a waste of time

I had never heard the term conflict minerals
until recently when headlines about all the graft in the
new financial reform bill hit news wires. "The passage, tucked into the bill's Miscellaneous Provisions, will
require thousands of U.S. companies to disclose what steps they are taking to ensure that their products,
including laptops, cellphones and medical devices, don't contain
from the Congo." The end result is raising the cost of products. This is another
2,000+ page bill that neither lawmakers nor president has read before passing. Like with the 2,000+ page health
care reform bill, they had to "pass the bill so you can find out what's in it" (Pelosi

America's Best Colleges
Forbes just published their list of the nation's top colleges. "Our list of more than 600 undergraduate
institutions is based on the quality of the education they provide, the experiences of the students and how much
they achieve." It includes liberal arts and engineering colleges. Princeton took the lead for tech schools while
snatching #2 overall. Military colleges - West Point, Naval Academy, etc., ranked honorably. Here are a few of
the most notable tech colleges. My alma matter, Univ. of VT, an engineering school, came in at a dismal 329.
Where does yours rank?
2 Princeton U.
4 U.S. Mil. Acad. (W. Point)
6 Stanford U.
8 Harvard U.
11 U.S. Air Force Academy

Electronic Design magazine just published the results of their survey to determine the best employers in 2009,
based on a somewhat nebulously defined grading method. An extensive report on Boeing occupies about 1/3 of the
article's text, though Boeing rated only at #16. Overall employee growth vs. 2008 was -5.5%, sales growth was
-8.3%, R&D was -3.7%. Not rosy.

is a dedicated coterie of collectors for just about everything imaginable, from carnival glass goblets to...
antique personal computers. Labeling a PC as "antique" is kind of a stretch, though, since the word usually
pertains to items at least 50 years old, an usually 100 years old or more. The Altair 8800 shown here was sold
in 1975, a mere 35 years ago. It was based on the Intel 8080 CPU. The Altair was the computer on which Bill
Gates and Paul Allen initially developed
, and one in like-new condition fetches a fair price. Other early PCs like the Sinclair (remember the
