Computer Security For Beginners

Don’t put any information that you don’t want exposed on any computer system that is connected to anything. Consider using a second computer that is not connected or a portable USB drive that can be unplugged or encrypted. Don’t connect any computer system to any other system or network of system without considering possible negative […]

1948 – Moravec – bio

Hans Moravec was born in Austria in 1948 and has contributed influential work in robotics and artificial intelligence. He has also done work in the fields of transhumanism and space tethers (space elevator). In 1998, in “Mind Children”, he wrote, “it is comparatively easy to make computers exhibit adult level performance on intelligence tests or […]

timeline of calculating machines

-3,000 – abacus 1614 – logarithms – by John Napier 1622 – slide rule invented by Oughtred 1623 – calculating clock by Schickard could add and subtract up to six places 1642 – Pascal built an “arithmetical machine” which used wheels linked by teeth, capable of automatic carrying to the next place 1668 – Morland […]

Algorithm Discovers New Superconductor

In nature, random genetic variations produce results that are sorted by survival. Over time, the best working variations reproduce more often, creating the process we call evolution. Evolutionary algorithms follow the same concept, trying small variations to advance the solution of a problem. An evolutionary algorithm designed to predict stable crystal structures has discovered a […]

1946 – ENIAC

In 1947, the Electronic Numerical Integrator And Computer (ENIAC) became the first general purpose electronic computer. It cost $500,000 to build, used 19,000 vacuum tubes, measured 30 feet by 50 feet and weighed 30 tons. There was no software for the machine. It operated like a large array of adding machines wired together. Programming was […]

1815 – Lovelace – bio

Born in England in 1815, Ada Augusta Byron married William King, becoming Ada Augusta King, but has been known as Ada Lovelace because her husband was named Earl of Lovelace, making her the Countess of Lovelace. Ada Lovelace studied Babbage’s “difference engine”, and earned the distinction of being called the first programmer because she published […]

1815 – Boole – bio

George Boole was born in Lincoln, England in 1815 and was a mathematician. He is most known for his work reducing logic to a form of algebra. In 1854, Boole’s book on logic, “An Investigation of the Laws of Thought on Which are Founded the Mathematical Theories of Logic and Probabilities” was published. This created […]

1791 – Babbage – bio

Charles Babbage was born in London, England, in 1791 and was a mathematician and inventor who is mostly known for designing the first calculating machine, that he called a “difference engine”. Babbage had the idea that tables of logarithms “might be calculated by machinery”, which would save time and reduce errors. He went on to […]

Computer Brains

FACETS (Fast Analog Computing with Emergent Transient States) works at reproducing brain-like processing using computer hardware. FACETS (Fast Analog Computing with Emergent Transient States) – [] The goal of the FACETS project is to create a theoretical and experimental foundation for the realisation of novel computing paradigms which exploit the concepts experimentally observed in […]

Oblong G-Speak

The link below includes a video demonstration of gesture based computer interface technology that is similar to the fictional interface shown in “Minority Report”. Oblong G-Speak The SOE’s combination of gestural i/o, recombinant networking, and real-world pixels brings the first major step in computer interface since 1984; starting today, g-speak will fundamentally change the way […]
