On January 3, 2018 computer security experts have discovered two major security flaws in the microprocessors inside nearly all of the world’s computers. The two problems, called Meltdown and Spectre, could allow hackers to steal the entire memory contents of computers, including mobile devices, personal computers and servers running in so-called cloud computer networks.
On January 5, 1909 was born Stephen Cole Kleene. He was an American mathematician. He was one of the students of Alonzo Church, along with Rózsa Péter, Alan Turing, Emil Post, and others. Kleene is best known as a founder of the branch of mathematical logic known as recursion theory, which subsequently helped to provide the foundations of theoretical computer science. Kleene’s work grounds the study of computable functions. A number of mathematical concepts are named after him: Kleene hierarchy, Kleene algebra, the Kleene star (Kleene closure), Kleene’s recursion theorem and the Kleene fixpoint theorem. He also invented regular expressions in 1951 to describe McCulloch-Pitts neural networks, and made significant contributions to the foundations of mathematical intuitionism.
On January 6, 1955 was born Susan Beth Horwitz.She was an American computer scientist noted for her research on programming languages and software engineering, and in particular on program slicing and dataflow-analysis.
On January 7 1943 died Nikola Tesla. He was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
On January 8, 1923 was born Joseph Weizenbaum. He was a german-american computer scientist and a professor at MIT. The Weizenbaum Award is named after him. He is considered one of the fathers of modern artificial intelligence.
