When Grace Hopper gets mentioned, there tends to be an uncomfortable silence about COBOL. COBOL is actually quite interesting, since it was a serious effort to make programming more accessible and a commercial success. It's also universally reviled by people who do programming for fun.
Beyond the gender stereotype of women being bad at tech, there is also the stereotype that women don't do technical tinkering for fun. It's a bit unfortunate that Hopper's most famous accomplishment ended up becoming the shorthand for programming as dreary, unfun 9-to-5 bureaucratic grind.
Today is Ada Lovelace Day, when STEM enthusiasts highlight the work of modern and historical women scientists, engineers, and mathematicians. If you run a blog, you may want to participate by posting about a woman in a STEM field whom you admire. But I'd love to have people share women scientists/mathematicians/authors in the comments that they think we could all stand to read more about.
