San Francisco’s open source voting project is quickly becoming a reality. Mayor Ed Lee’s proposed budget includes $300,000 towards planning and development of an open source voting system that would allow the city to own and share the software. Dominion Voting Systems, formerly known as Sequoia Voting, has provided San Francisco’s voting technology for years, but its contract with the city and county expires at the end of the year, according to KQED News. “When you rely on an outside vendor, it’s their technology, which is proprietary and confidential, and the public really doesn’t have access to the code that they’re relying on,” said Supervisor Scott Wiener, who’s running for state Senate. “It’s very ‘black box,’ so we just have to have faith that their machines are producing accurate results,” he told KQED.
