Is Information Technology Destroying the Middle Class?
While optimists argue that though technology always destroy jobs, it also creates new jobs, pessimists argue that the speed in which information technology is currently destroying jobs is unparalleled.There Is Nothing New Under the Sun
Centuries before George Boole and Charles Babbage, the notion of binary encoding was well known and apparently even used! Julius Caesar was known to use a simple rotational cipher. Francis Bacon devised a binary encoding scheme …DEPARTMENT: Letters to the Editor
Software Engineering, Like Electrical Engineering
Though I agree with the opening lines of "A New Software Engineering" (Dec. 2014) outlining the "promise of rigorous, disciplined, professional practices," we must also look at "craft" in software engineering if we hope to raise …DEPARTMENT: BLOG@CACM

Technical Perspective: The Equivalence Problem For Finite Automata
As the equivalence problem is essential in many applications, we need algorithms that avoid the worst-case complexity as often as possible. In "Hacking Nondeterminism with Induction and Coinduction," Filippo Bonchi and Damien …Hacking Nondeterminism with Induction and Coinduction
We introduce bisimulation up to congruence as a technique for proving language equivalence of nondeterministic finite automata.COLUMN: Last byte
