Today, let’s remember Niklaus Wirth, who was born on this day in 1934. Wirth received the in 1984 for developing a sequence of innovative computer languages, EULER, ALGOL-W, MODULA and PASCAL. PASCAL has become pedagogically significant and has provided a foundation for future computer language, systems, and architectural research.

The effectiveness of Wirth’s systems, and his ability to build complex systems with small teams, relied on his constant search for elegant simplicity—for what could be left out. Over time his language designs and compiler techniques became, in some respects, simpler and more efficient rather than, as is almost universal, slower and more complex. In 1995 he warned that “The plague of software explosion is not a ‘law of nature.’ It is avoidable, and it is the software engineer's task to curtail it.”

Happy Birthday to Richard Karp! Karp received the 1985 for his continuing contributions to the theory of algorithms including the development of efficient algorithms for network flow and other combinatorial optimization problems, the identification of polynomial-time computability with the intuitive notion of algorithmic efficiency, and, most notably, contributions to the theory of NP-completeness. Karp introduced the now standard methodology for proving problems to be NP-complete which has led to the identification of many theoretical and practical problems as being computationally difficult. https://amturing.acm.org/award_winners/karp_3256708.cfm

in 1959 MIT spin-off DEC began shipping a minicomputer called the PDP-1.

Little did they know, it would be used to develop the first multiplayer video game Spacewar & usher in US hacker culture: http://bit.ly/2XFazMu
