"Programming Language Cultures dispels the hype around computation that colors so much previous analysis. Impeccable research and technical mastery combine with the keen sensibilities of a philologist to demonstrate, finally, a welcome intellectual maturity in digital studies." Aden Evens, Dartmouth College "Instead of chasing the latest in artificial intelligence, cryptocurrency, or social media, Lennon's approach is to historicize the foundation on which all apps, algorithms, and platforms are built: programming languages old and new." Warren Sack, University of California, Santa Cruz "This readable and multidisciplinary book provides many valuable historical insights into programming languages and the world of software development."Mark Priestley, Technology and Culture
