Hacktoberfest, an annual event held in October, encourages developers to contribute to open source projects, with this year's focus on socially impactful initiatives. In partnership with DigitalOcean, Twilio, and several highlighted projects, participants can contribute to a range of projects aimed at making a positive difference in the world. These projects include alex, which promotes inclusive language; REFUGE Restrooms, which maps safe restrooms for gender-nonconforming individuals; GliaX, which develops open source medical devices; HospitalRun, which improves software for charitable hospitals; If me, a mental health app; Talk, a commenting platform by Mozilla and major news outlets; the Humanitarian OpenStreetMap Team, which aids disaster management; and OptiKey, an on-screen keyboard for Motor Neuron Disease patients. Contributors of all levels can participate, and those completing the Social Impact Collection challenge will earn a badge on their GitHub Community Forum profile.
