In the 1950s, legendary behaviorist B.F. Skinner debuted his version of a “teaching machine,” based on the 1924 invention of Ohio State University psychology professor Sidney Pressey. The contraption was loaded with a piece of paper with questions, and students pressed keys indicating the correct answer, at which point another question would appear. Both Pressey and Skinner ran into similar problems, though, failing to implement the technology in schools. Educators weren’t convinced of the machine’s benefit, which prioritized individually paced learning not conducive to students of the same age moving through a grade level at the same time.
the result is RE#, the first general-purpose regex engine to support intersection and complement with linear-time guarantees, and also the overall fastest regex engine on a large set of benchmarks. we also wanted to address some more things along the way, like returning the correct matches (the ones you meant, leftmost-longest), when the default semantics are given by the PCRE implementation. or put another way, “it’s correct if it does whatever the one that blows up and causes denial of service does”.
