cronexpr is a library that parses and drives crontab expressions, requiring a timezone to determine the next timestamp. It supports standard and non-standard extensions, such as Last day of month (L) and Nearest weekday (1W). The crate implements Vixie’s cron behavior, which can result in unexpected outcomes due to intersect or union modes. Edge cases, […]
In this paper presented at the annual Usenix Meeting in 2006, Stephen C Johnson questions the traditional algorithms and data structures taught to computer science students, emphasizing the changing nature of machines on which these algorithms run. Using cycle counters on desktop machines, the author examines the impact of memory access patterns on performance. Surprisingly, […]
Dobble (Spot It!) is a card game where special circular cards use symbols. Cards have one symbol in common, designed for various gameplay options. Exploring the design process mathematically reveals no simple formula for the number of symbols and cards. Empirical play and examples show how to create decks with requirements for unique cards and […]
The author embarked on a journey to analyze Italian music as a network, connecting artists to the bands they contributed to from the 1902 of Enrico Caruso to the present. The resulting bipartite network revealed interesting findings about the temporal proximity of bands and the genre clusters formed within Italian music history. Surprisingly, Gianni Maroccolo […]
DoNotPay, originally promoted as the “world’s first robot lawyer,” was found by the FTC to have made deceptive claims without testing its AI chatbot’s output against a human lawyer’s level. DoNotPay did not employ attorneys to verify outputs or validate legal claims, leading to an FTC settlement where the AI startup agreed to pay $193,000 […]
