Hello, I'm Synoman Barris. I noticed that you made a change to an article, History of computer science, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Megan B....  It’s all coming to me till the end of time  16:33, 28 January 2022 (UTC)
