Email Question Hi Techtalk. You all sent me an email 1 February 2007 about the continuation of the Tech Talk radio program, but I haven't received anything since, although I have listened to the program. Is there any difference of getting a newsletter than being in the Forum? Also, although Dr. Shurtz mentioned where to go to get on the Forum, I don't see it where he said it was. Also, what is "Cognos?" Thanks for your reply, hopefully.

Hi Techtalk. You all sent me an email 1 February 2007 about the continuation of the Tech Talk radio program, but I haven’t received anything since, although I have listened to the program.

The newsletter mailing list ensured that you will receive a newsletter. One is due out shortly.
The Forum is actually a discussion area (with real time chat during the show and threaded discussion between the shows).
You can join the Forum by going to www.stratford.edu and clicking the the Tech Talk Radio menu at the top (right).
The drop down menu will have a Join the Forum entry.
Cognos is a business intelligence software company. They produce a podcast called Radio Cognos. They also call it Cognos Tech Talk, so you may have picked it up via the search engines.

Ada Lovelace (Augusta Ada Byron King, Countess of Lovelace)
Ada Byron was the daughter of a brief marriage between the Romantic poet Lord Byron and Anne Isabelle Milbanke
Ada married William King. King inherited a noble title, they became the Earl and Countess of Lovelace.
Lady Byron wished her daughter to be unlike her poetical father, and she saw to it that Ada received tutoring in mathematics and music, as disciplines to counter dangerous poetic tendencies.
Ada met Charles Babbage in 1933 when she was 17 and they began a voluminous correspondence on the topics of mathematics, logic, and ultimately all subjects.
Charles Babbage, Lucasian professor of mathematics at Cambridge, was known as the inventor of the Difference Engine, an elaborate calculating machine that operated by the method of finite differences.
Babbage held the same post as Sir Isaac Newton (known for the equations of motion and calculus) and Steven Hawkings (Black holes and Hawkings radiation).
Babbage had made plans in 1834 for a new kind of calculating machine (although the Difference Engine was not finished), an Analytical Engine.
His Parliamentary sponsors refused to support a second machine with the first unfinished, but Babbage found sympathy for his new project abroad.
In 1842, an Italian mathematician, Louis Menebrea, published a memoir in French on the subject of the Analytical Engine.
Babbage enlisted Ada as translator for the memoir, and during a nine-month period in 1842-43, she worked on the article and a set of Notes she appended to it.
She rightly saw it as what we would call a general-purpose computer.
She understood the importance of keeping the calculating machine and the program separated.
Proposed a method to computer Bernoulli numbers using the analytical engine
The methods she proposed included loops, branches, and conditional statements.
She is thus credited with being the first programmer.
Babbage’s analytical machine anticipated most of the features of computers that were invented over a hundred years later
The programs for his machine developed by Babbage and Lovelace anticipated computer programming methods that were developed over a hundred years later.
In May 1979, the new DOD-1 programming language was named Ada in her honor.
History Mechanical Computers
The abacus, a simple counting aid, may have been invented in Babylonia (now Iraq) in the fourth century B.C.
The Antikythera (an ti ki ‘theer uh) mechanism, used for registering and predicting the motion of the stars and planets, is dated to the first century B.C. It was discovered off the coast of Greece in 1901.Accounted for leap year, irregularity in the Moon’s orbit.
Wilhelm Schickard builds the first mechanical calculator in 1623. It can work with six digits, and carries digits across columns. It works, but never makes it beyond the prototype stage. Schickard is a professor at the University of Tubingen, Germany.
Blaise Pascal builds a mechanical calculator in 1642. It has the capacity for eight digits, but has trouble carrying and its gears tend to jam.
Joseph-Marie Jacquard invents an automatic loom controlled by punch cards.
Charles Babbage conceives of a "Difference Engine" in 1820 or 1821. It is a massive steam-powered mechanical calculator designed to print astronomical tables. He attempts to build it over the course of the next 20 years, only to have the project cancelled by the British government in 1842.
Babbage’s next idea is the Analytical Engine – a mechanical computer that can solve any mathematical problem. It uses punch-cards similar to those used by the Jacquard loom and can perform simple conditional operations.
Augusta Ada Byron, the countess of Lovelace, met Babbage in 1833. She describes the Analytical Engine as weaving "algebraic patterns just as the Jacquard loom weaves flowers and leaves."
Her published analysis of the Analytical Engine is our best record of its programming potential. In it she outlines the fundamentals of computer programming, including data analysis, looping and memory addressing.
