This is Dave Edstrom's personal blog called Photons and Electrons. This blog is about technology, as well as some of my personal interests. I am the CEO/CTO of Virtual Photons Electrons. I was the CTO for MEMEX for three years, the President and Chairman of the Board for the MTConnect Institute from May 2010 to January 2014 and prior to that I spent 23 years at Sun Microsystems.
As Mr. Robinson wrote on November 27th, 2008: "May you live in interesting times" is supposed to be an ancient Chinese curse, but I can't find evidence that the saying is Chinese at all, much less that it's ancient. One of the earliest reliable citations seems to be a 1950 short story by the British science-fiction author Eric Frank Russell, writing under the pen name Duncan H. Munro, who quotes the imprecation and then adds: "It isn't a curse any more. It's a blessing."
"MTConnect has its roots at AMT. The members and administrators of this organization, which represents machine tool builders and other manufacturing technology suppliers, became aware of the need for interoperability when experts from the computer industry were invited to discuss the needs of manufacturing at its fall 2006 annual meeting for members. The message from these experts was blunt: Unless machine tools and other types of computerized manufacturing equipment can readily communicate critical data in a standard format, the industry cannot automate rapidly enough to keep up with global demands. Integration on the shop floor would be difficult or impossible. Progress in productivity gains and cost reductions would be stymied.
MTConnect has been officially out for just one year and it is amazing how much industry and customer success we have seen in such an incredibly short amount of time.
The response to this wake-up call was the MTConnect project, for which AMT put up more than a $1 million in seed money in January 2007. The committee formed to pursue this initiative brought together computer science researchers from the University of California-Berkeley, the Georgia Institute of Technology and other institutions to conceive, design and develop a draft communications standard. Paul Warndorf, AMT’s vice president of technology and liaison to the MTConnect development committee, recalls highlights of that development effort. "Early on we knew that the standard would have to be open and extensible; use existing standards such as XML or HTTP borrowed from the Internet; be easy to understand and implement; and not conflict with proprietary communications technology already in place. So that’s how we made it."
The Wealthy Barber is one of my favorite books to recommend to young people because of the clarity of its stories. Neil Groundwater initially told me about this great book.
“Two twenty-two-year-old twins decide to start saving for retirement. One opens an IRA, invests two thousand dollars a year for six years, and then stops. His IRA compounds at twelve percent a year … very good. The second twin procrastinates and doesn’t open an IRA until the seventh year — the year his brother stopped. The second twin then contributes two thousand a year for thirty-seven years. He, too, earns a rate of twelve percent a year. At age sixty-five, they go out for dinner to compare their IRA holdings. The second twin, who is fully aware that his brother stopped contributing thirty-seven years earlier, is confident that his IRA will be worth at least ten times as much. What do you think, Cathy?”
“I think he’s wrong … or you woulnd’t be telling us the story,” was her clever rationale.
“Yeah, yeah,” Roy laughed. “At age sixty-five, they would both have approximately one million two hundred thousand dollars.”
The first brother paid $2,000 a year for six years. He contributed a total of $12,000. The second brother contributed $2,000 a year for thirty-seven years. He paid a total of $74,000 — more than six times his sibling!"
The article hits on the main point that Kao achieved when it states:
"While light normally passes through glass and does not go around corners, Kao's work -- aided by that of many other scientists and engineers -- is proof that under the right conditions, those generalities do not hold true. Sometimes light can be kept inside a strand of glass, like water in a pipe.
It seemed hopeless until Kao and a theoretician colleague, George A. Hockham, made some measurements and calculations. They determined that if the impurities scattering the light rays could be removed from the glass, and if they used a wavelength that the glass molecules could not absorb, then much, much more light would stay inside the fiber."
The article hits on the main point that Willard S. Boyle and George E. Smith achieved when it states:
"In the late 1960s, at Bell Laboratories in New Jersey, they were working on ways to improve memory devices -- a way of storing information acquired over time. The ultimate goal was to eliminate the annoying echo that sometimes occurred in very-long-distance telephone calls.
They used an array of small squares made from silicon-based semiconductor material. "Semiconductors" are capable of generating an electrical charge, although not as readily as metals and other conductors (hence their name). Electrodes placed nearby can then be used to hold the charges in place and keep them from dispersing.
Like a row of dominoes of different face value, a line of small semiconductor squares called "pixels" outfitted with electrodes were able to hold a row of different charges. If a voltage was then applied to the array in the right fashion, the charges could be moved off the pixels and "read out."
After some pondering, they realized that light falling onto the semiconductor chips was being transformed into electrical energy. (Explaining that phenomenon, called the "photoelectric effect," is what won Albert Einstein his own Nobel Prize in Physics in 1921.) With the lab lights off, that interference disappeared.
"They put two and two together and they realized they had made an imaging device," said J. Anthony Tyson, who was at Bell Labs with the two men and is now a professor of physics at the University California at Davis.
By combining the photoelectric effect -- light's tendency to kick electrons out of atoms, creating a charge -- and the ability to hold and move an entire array of charges in an organized fashion, they created the basis for digital photography."
The article is a must read because of the tremendous benefit that all of us have seen in our lives from the Internet to digital cameras - to just name a few.
On the 11th hour of the 11th day of the 11th month of 1918 an armistice between Germany and the Allied nations came into effect. On November 11, 1919, Armistice Day was commemorated for the first time. In 1919, President Wilson proclaimed the day should be "filled with solemn pride in the heroism of those who died in the country’s service and with gratitude for the victory". There were plans for parades, public meetings and a brief suspension of business activities at 11am.
In 1926, the United States Congress officially recognized the end of World War I and declared that the anniversary of the armistice should be commemorated with prayer and thanksgiving. The Congress also requested that the president should "issue a proclamation calling upon the officials to display the flag of the United States on all Government buildings on November 11 and inviting the people of the United States to observe the day in schools and churches, or other suitable places, with appropriate ceremonies of friendly relations with all other peoples."
An Act (52 Stat. 351; 5 U. S. Code, Sec. 87a) was approved on May 13, 1938, which made November 11 in each year a legal holiday, known as Armistice Day. This day was originally intended to honor veterans of World War I. A few years later, World War II required the largest mobilization of service men in the history of the United States and the American forces fought in Korea. In 1954, the veterans service organizations urged Congress to change the word "Armistice" to "Veterans". Congress approved this change and on June 1, 1954, November 11 became a day to honor all American veterans, where ever and whenever they had served.
In 1968 the Uniforms Holiday Bill (Public Law 90-363 (82 Stat. 250)) made an attempt to move Veterans Day to the fourth Monday of October. The bill took effect in 1971. However, this caused a lot of confusion as many states disagreed with this decision and continued to hold Veterans Day activities on November 11. In 1975, President Gerald R. Ford signed Public Law 94-97 (89 Stat. 479), which stated that Veterans Day would again be observed on November 11 from 1978 onwards. Veterans Day is still observed on November 11.

"But there was no other computer to talk to. So a month later, Stanford Research Institute received its interface message processor, or IMP, connected it to their host computer, and we created the first piece of the backbone network when a 50-kilobit-per-second line was connected between UCLA and SRI.
What we wanted to do was send a message essentially from UCLA to SRI's host. And frankly, all we wanted to do was log in -- to type an l-o-g, and the remote time-sharing system knows what you're trying to do."
