HISTORY OF
ETHERNET In 1973, Robert (Bob) Metcalfe was a recent Harvard
Ph.D. graduate working at Xerox's Palo Alto Research Center (PARC). In the course of his work training US
military personnel to use the world’s first operational packet switching
network--known as the Advanced Research Projects Agency Network (ARPANET)--he
often traveled to Washington D.C. While
staying at a friend’s apartment in the nation’s capitol, the young engineer
came across a book of conference proceedings from the 1970 American Federation
of Information Processing Societies (AFIPS) conference. In the proceedings was a hidden gem--a paper
written by Norman Abramson entitled “The Aloha System--Another Alternative for
Computer Communications.” It described
the development of an innovative radio-based network of computers that came to
be known as ALOHAnet. And although he
disagreed with some aspects of the technology model, the paper quickly caught
Metcalfe’s attention. Inspired by the
ALOHAnet paper, upon his return to PARC and with the help of David R. Boggs, he
began putting his thoughts to paper. Using an IBM Selectric Typewriter with an
Orator ball, Metcalfe typed a memo and sketched a quick schematic that would
forever change both networking and the world at large. And so on May 22, 1973 Ethernet was
born. After months of effort built on
Metcalfe’s ideas and Boggs’ help in designing and debugging the necessary
network hardware, the first working Ethernet prototype, a 2.94 Mbps CSMA/CD
system connecting more than 100 workstations on a 1 Km cable, went live on
November 11, 1973. Based on its
demonstrated success, Xerox would go on to patent Ethernet in 1975. In August 2012, IEEE joined other leading
global organizations, including the Internet Architecture Board (IAB), Internet
Engineering Task Force (IETF), Internet Society and World Wide Web Consortium
(W3C), to announce its support of OpenStand, a jointly developed set of principles
establishing a modern paradigm for global, open standards. Under OpenStand, the economics of global
markets in conjunction with technology innovation help facilitate continued
worldwide open standards development and deployment, including standards for
the next generation of Ethernet speeds of 100G, 400G, and beyond. http://standards.ieee.org/events/ethernet/history.html
America’s Quirky Rest Stops Are Vanishing by Jordan G. Teicher Before
national chains like McDonald’s and Dunkin Donuts largely supplanted them as
destinations for relaxation and amusement, publicly funded rest stops were an
integral part of driving for interstate travelers. Ryann Ford started
paying attention to rest areas while on assignment for Texas Monthly. After doing some research online, she learned
how rest stops developed alongside the Interstate Highway System in the 1950s,
but were being closed or demolished as the recession shrunk state
budgets. See beautiful pictures at http://www.slate.com/blogs/behold/2014/12/12/ryann_ford_photographs_america_s_rest_stops_in_her_series_the_last_stop.html
Around the country, libraries are slashing their print
collections in favor of e-books,
prompting battles between library systems and print purists, including not only
the pre-pixel generation but digital natives who represent a sizable portion of
the 1.5 billion library visits a year and prefer print for serious
reading. Millennials prefer reading in
print. http://www.washingtonpost.com/local/why-digital-natives-prefer-reading-in-print-yes-you-read-that-right/2015/02/22/8596ca86-b871-11e4-9423-f3d0a1ec335c_story.html Some of the clashes have been
heated. In New York, protesters outside
the city’s main branch have shouted:
“Save the stacks! Save the stacks!”
In Northern Virginia, the Fairfax County library system chief recently
mused that the Friends of the Library were no longer friends—a feud fueled by
outrage over a print collection that has shrunk by more than 300,000 books
since 2009. The drop in the District of
Columbia is even more dramatic: Nearly
1 million books have vanished since 2009.
“To say Gutenberg’s days are over is a terrible mistake,” said Dennis
Hays, a former U.S. ambassador and chairman of Fairfax Library Advocates, a
group of residents at war with library officials. “Nothing can take the place of a book.” Librarians are feeling the
heat. “We’re caught between two worlds,”
said Darrell Batson, director of the Frederick County Public Libraries system
in Maryland, where the print collection has fallen 20 percent since 2009. “But libraries have to evolve or die. We’re probably the classic example of
Darwinism.” The evolution of information
flow has forced their hands, librarians say.
Just as books advanced from slabs of parchment to paperbacks, they are
transforming again, from paper to pixels.
With Plato only a download away, libraries have lost their monopoly on
knowledge. In evolving, librarians are
steering tight acquisition budgets to e-books, which are more expensive than
print because, among other reasons, publishers fear large databases of free
e-books will hurt their business. E-book
spending has grown from 1 percent of library budgets to 7 percent, according to
a Library Journal survey. One library in
San Antonio went much further, opening a bookless, all-digital branch called
BiblioTech. Meanwhile, print book
budgets are slipping fast—from 67 percent of acquisitions in 2008 to 59 percent
in 2015—with reference titles bearing the biggest cuts so far. Asked why, Batson turned to his computer,
opened his browser and typed www.google.com.
“That’s why,” he said. With the
newfound physical space, libraries are adding rooms for community meetings,
hacker spaces with 3-D printers, and entrepreneur centers to help small
businesses.

For centuries, artists have reclaimed
items to turn them
into their art: whether it’s reusing
canvases (as X-rays demonstrate almost all the old masters did) or
incorporating found items into sculptures, such as pop artist Robert
Rauschenberg’s creative way of reusing items ranging from bicycles to roosters.

Charles
Gates Dawes (1865–1951) was an American banker and politician who was the 30th Vice
President of the United States (1925–1929). For his work on the Dawes Plan for World War I reparations he was a cowinner of the Nobel Peace Prize in 1925. Dawes
served in the First World War, was the Comptroller
of the Currency, the first director
of the Bureau of the Budget, and, in
later life, the Ambassador
to the United Kingdom. Dawes was born in Marietta,
Ohio, the son of a Civil War officer Rufus
Dawes and Mary Beman Gates
Dawes. He graduated from Marietta
College in 1884, and from the Cincinnati Law School in 1886. Dawes was admitted to the bar in Nebraska, and
he practiced in Lincoln,
Nebraska from 1887 to
1894. Dawes was a self-taught pianist
and a composer. His composition,
"Melody in A Major" in 1912 became a well-known piano and violin
song, and it was played at many official functions as his signature tune. It was transformed into the pop song "It's All in the Game" in 1951 when Carl
Sigman added lyrics. Tommy
Edwards' recording of
"It's All in the Game" was a number one hit on the American Billboard record chart for six weeks in the fall
of 1958. Edwards' version of the song also hit number
one on the United Kingdom chart that year. Since
then, it has since become a pop standard, recorded hundreds of times by artists
including Cliff
Richard, The
Four Tops, Isaac
Hayes, Jackie
DeShannon, Van
Morrison, Nat
"King" Cole, Brook
Benton, Elton John, Mel Carter, Donny and Marie Osmond, Barry
Manilow, and Keith
Jarrett. Dawes is the only Vice-President
or winner of the Nobel Peace Prize to be credited with a No. 1 pop hit. https://en.wikipedia.org/wiki/Charles_G._Dawes

When Walter Farley published The Black Stallion in 1941, he was an unknown college journalism
student. However, more than 60 years and
20 Black Stallion stories later, people around the world know him as the person
behind the most famous fictional horse of the 20th century. Growing up in New York City, Walter Farley
dreamed of having a horse of his own. He
sought out books about horses and spent as much time as he could with his Uncle
Bill, a professional horseman. Walter’s
sons, Tim and Steven Farley, recall him later saying he decided to write The
Black Stallion because he was often disappointed by the quality of horse
stories he read. Walter Farley began
working on The Black Stallion as a high school student. Walter Farley finished the book while
majoring in Journalism at Columbia University.
World War II prevented Farley from working on a sequel immediately. When
he returned from the war, Farley resumed the adventures of Alec and the Black
in The Black Stallion Returns and The Son of the Black Stallion. Farley then delighted his readers with the
introduction of a new boy and wild stallion, Steve Duncan and Flame, in The
Island Stallion. He continued to write
books about horses and he wrote several books for his own children, who were
too young to read the Black Stallion novels.
Additionally, he wrote a biography of the great racehorse, Man
O’War. In all, Walter Farley authored 34
books, which were translated and printed in more than 20 countries.

On July 14,
2015, New Horizons, a piano-sized spacecraft that was launched in January of 2006, became the
first space probe to make a close flyby of Pluto. Using its seven instruments, the probe is
expected to deliver the first detailed scientific information about the rocky
and icy dwarf planet. Starting at 5:50
a.m. ET on July 15, the spacecraft is expected to begin sending the most detailed images of
the dwarf planet that scientists have ever seen, along with mapping and
measurements about the planet, its atmosphere and moons. The new images are expected to be 10 times
higher in resolution than previous images the probe has sent back as it
approached Pluto. Sharon

Clyde William Tombaugh (1906–1997) was an American astronomer. Although he is best known for discovering the dwarf planet Pluto in 1930, the first object to be discovered in what would
later be identified as the Kuiper belt,
Tombaugh also discovered many asteroids;
he also called for the serious scientific research of unidentified flying objects,
or UFOs. Tombaugh was born in Streator, Illinois.
After his family moved to Burdett, Kansas in 1922, Tombaugh's plans for
attending college were frustrated when a hailstorm ruined his family's farm crops. Starting in 1926, he built several telescopes with lenses and mirrors by
himself. He sent drawings of Jupiter and Mars to the Lowell Observatory,
which offered him a job. Tombaugh worked
there from 1929 to 1945. Following his discovery of Pluto, Tombaugh earned bachelor's and
master's degrees in astronomy from the University of Kansas in 1936 and 1938. The asteroid 1604 Tombaugh, discovered in 1931, is named after
him. He discovered hundreds of
asteroids, beginning with 2839 Annette in 1929, mostly as a by-product of his
search for Pluto and his searches for other celestial objects. Tombaugh named some of them after his
wife, children and grandchildren. The Royal
Astronomical Society awarded
him the Jackson-Gwilt Medal in 1931. In August 1992, JPL scientist Robert Staehle called
Tombaugh, requesting permission to visit his planet. "I told him he was
welcome to it," Tombaugh later remembered, "though he's got to go one
long, cold trip." The call eventually led to the launch of the New Horizons space
probe to Pluto in 2006. https://en.wikipedia.org/wiki/Clyde_Tombaugh

July 15, 2015 On this date in 484
BC, the Temple of
Castor and Pollux in ancient Rome was dedicated. On this date in 1799, the Rosetta Stone was found in the Egyptian village of Rosetta by
French Captain Pierre-François
Bouchard during Napoleon's Egyptian
Campaign.
