Summer 2013

Zephyr whispers the Summer Solstice in at 1:04 am; this unique day in New York City is marked by 15 hours of daylight. In Anchorage, Alaska, 19 hours of daylight is experienced. On this day, the Harlem Internet Computer Access Program ends our HICAP 2012-2013 year. This year, we introduced www.hicapv.blogspot.com, our Virtual Learning Lab; which translates and disseminates technical computer education facts.
The blog that you are currently visiting translates scientific data, provides technical pertinent information and highlights accomplishment.
Today's posting of Scientific Notation at the Virtual Leaning Lab will be the last lesson discussion for HICAPV until Fall 2013.

Enjoy Summer!

IPv6

IPv6 is a hot topic at the Internet Society. IPv6 means Internet protocol version 6. Internet protocol is the communication system that directs Internet traffic. IP addresses are the unique numbers assigned to each device: computer, printer, etc. IPv6, developed by the Internet Engineering Task Force (IETF), is slated to replace the current IPv4 to remedy address exhaustion. The easiest way to recognize which version an IP address is by the separators. IPv4's numeric sequence is separated by decimals. The IPv6 sequence is separated by colons and has a 128 bit address; version 4 is only 32 bit. Internet Assigned Numbers Authority (IANA) is the global management agent which oversees five regional registries and assigns blocks of IP addresses to our local Internet Service Providers (ISP).

 

Some of the advantages of IPv6 are:

• authentication
• cost efficient bandwidth cost limits
• forward flexibility for future options
• real-time quality of service options
• expanded addressing; supports more levels of addressing hierarchy, more addresses; auto configuration of addresses
• upper layer transport
• has a scope field to multicast addresses and anycast to send a data package to any group of nodes (Nodes are hosts that are not routers)

The Internet Protocol Suite has an application layer, transport layer and link layer.
Although this topic is very important, you will receive the advantages of this protocol without knowlege of why or how it works; but it is fun to know.

Women's History Month honors Dr. Dorothy I. Height

Women’s History Month is a worldwide celebration that highlights accomplishments.

The Harlem Internet Computer Access Program dedicates the month of March to All Phenomenal Women who sustain the lives of others by always rising to the circumstantial occasion. For this reason HICAP pays homage to Dr. Dorothy Irene Height. In her activist support for all people, her organization created opportunities for children to reach their optimal potential. Dr. Height could be seen in the marble pillared corridors of her office at 633 Pennsylvania Avenue in Washington, D.C., just a stones throw from the White House; conducting business on behalf of Continental Societies, Inc. which has a Five-Point Programmatic Thrust—Health, Education, Employment, Recreation acronym HEER. Her program, also, embraces the Arts and Humanities. Dorothy Height continued to crusade tirelessly on behalf of others for seven decades.
As a youth, she was invited by First Lady Eleanor Roosevelt to spend a weekend of preparation for the World Youth Conference that was held at Vassar College.
Dorothy Height, known as an International Humanitarian, was a visiting professor at the University of Delhi in India in the 1950s. Awarded the Presidential Medal of Freedom in 1994; and in 2004, she received the Congressional Gold Medal for advocating for racial and gender equality.
The beauty of this humanitarian extended from her heart to her attire. Known for donning beautiful hats, she hosted a fabulous headwear extravaganza each spring showing artistically fashionable hats.
A Congressional Medal replica authorized by Public Law 108-162, was struck and features the image of Dr. Dorothy I. Height. In 2010, Congresswoman Norton introduced a bill to have the Post Office located at Two Massachusetts Avenue in Washington, DC named for Dr. Height. The building at 633 Pennsylvania Avenue where her offices were located is, now, known as the Dorothy I. Height Building.

We thank you, Dorothy
for living your enduring mission of service to all people.

First Day of Spring

Today is first day of spring and the first day of the Astrological Calendar. The Vernal Equinox begins today at 7:02 a.m. in the Northern Hemisphere. The sun sets at approximately 7:08 p.m. There is approximately an equal amount of day and night time hours, thus the equinox.
Time of sunrise and sunset reminds me of a scientific quatrain called,

'The Sun'

The sun neither sets nor rises
That is the stuff of poets dreams
The sun is affixed in a whirling universe
Life just isn't as it seems.

DASH

Techies love acronyms and abbreviations; it is their language. As you know, www is an abbreviation for the World Wide Web; which means that text can be transferred throughout the world to anyone with the hardware to receive it. Text is boring to non-techs. To provide more bells and whistles to the average computer user, http was put into place. HTTP means Hyper Text Transfer Protocol and when you see https://, you are entering a secure site; such as bank, governmental, etc. With http://, beyond just reading text, you are able to see and hear colorful video clips (once they load), yeah!
The Internet Society recently sent me an e-mail stating that a new standard is being applied that enables high quality media streaming called DASH,which stands for Dynamic Adaptive Streaming over http, nice. This newest technology is supported by Microsoft, Adobe, Google. DASH is predicted to take over the market by 2015, we shall see!

Black History Month

HICAP the Harlem Internet Computer Access Program

honors
CHARLES BOLDEN
for
Black History Month 2013

Charles Frank Bolden, Jr., is the first African American to permanently lead the National Aeronautics and Space Administration. Before coming to NASA, he logged over 6,000 hours in flying time serving as a United States Marine Aviator and test pilot.

Charles Bolden was chosen as an astronaut candidate in May of 1980. In 1981, he joined NASA as a proud African American astronaut who flew four missions logging 600 space hours before retiring. While at NASA, Mr. Bolden piloted the Space Shuttle Columbia to deploy the SATCOM KU Satellite used by us to downlink and to receive satellite TV. While piloting the Space Shuttle Discovery, he deployed the Hubble Space Telescope whose transmissions have inspired awe as they reveal the magnificent beauty of our universe.

After retirement, Charles Bolden was hired as Administrator in charge of NASA.
