Sophie Wilson she co-designed the ARM (Acorn RISC Machine) processor architecture in the 1980s. ARM powers the vast majority of smartphones, tablets, embedded devices, and many other systems today. Martine Rothblatt founded Sirius Satellite Radio (now SiriusXM), pioneering satellite-based digital audio broadcasting and related communications tech. She holds patents in satellite systems, global portable internet via low-Earth orbit, and navigation. Mary Ann Horton a key architect of Usenet (one of the earliest decentralized computer networks and a direct precursor to modern internet forums and discussion systems). She invented uuencode, the method that enabled binary file attachments in email and early online systems. Horton also contributed to Berkeley UNIX, which helped expand early internet infrastructure. Lynn Conway while at IBM in the 1960s, she invented generalized dynamic instruction scheduling (a form of out-of-order execution), a foundational technique still used in nearly all modern high-performance CPUs to boost speed and efficiency. I don't give a fuck about your political opinion but the trans community is awesome and has been a HUGE contributor to tech.
