Culinary recipes are archetypal algorithms, but cooking is not seen as related to programming (cf. Shore, 1985). Jaccard looms, machines that weave cloth, are the original use case for punchcards — physical pieces of paper that were used to program computers (Harlizius-Klück, 2017). Ada Lovelace invented the first computer program (Aiello, 2016). Women mathematicians and programmers worked with the first digital computer, the ENIAC (Kleiman, 2022). Grace Hopper invented the compiler (Beyer, 2012). Core rope memory was created through knitting copper wires by women for NASA’s Apollo missions (Rosner et al., 2018). Margaret Hamilton was Director of the Software Engineering Division that inter alia took humans to the Moon (Hamilton & Hackler, 2008). ... Ultimately, these are typical trends within capitalist patriarchy, where women’s — and all minoritised people’s contributions — are systematically hidden from the historical retelling of humanity’s achievements (also known as cryptogyny, the Matilda effect: Connell & Janssen-Lauret, 2022; Evans, 2020; Gage, 1883; Hicks, 2017; Kleiman, 2022; Lee Shetterly, 2016; Pozo & Padilla, 2019; Pozo-Sánchez & Padilla-Carmona, 2021; Rossiter, 1993; van den Brink & Benschop, 2012).” (Guest & Forbes 2023, pp. 2-3).
