Ada Lovelace, celebrated as the first computer programmer, wrote the initial computer program in 1843, long before computers existed. Ada Lovelace Day, founded in 2009 by Suw Charman-Anderson, is observed on the second Tuesday of October to honor her and other women in STEM. The day seeks to raise awareness of Lovelace's contributions and inspire activities such as building projects, reading comics, watching videos, and attending events. It's also a time to reflect on gender diversity in tech and support women in the field, encouraging actions like auditing Twitter to ensure diverse representation. Various resources, such as webcomics and motivational quotes, offer engaging ways to appreciate Lovelace's legacy and promote the inclusion of women in technology.
