The Tech Together hackathon will be held virtually this year, November 6-8, with the theme “Dear Future Me.” It’s “Boston’s largest student-run hackathon open to all female, femme, and non-binary individuals.” Those who identify as male may volunteer but not participate as hackers. For 36 hours from 6PM Friday to 11AM Sunday, there will be technical projects for teams and individuals, workshops, talks, networking opportunities. It’s free, and optional donations will be accepted for any of three organizations:  Black Tech Mecca, Reclaim the Block, and TechTogether. Register here.
