What I learned today is everyone should have the experience of watching a live soccer match with a Brazil-leaning crowd. Every ref call contested, excitement about every corner kick, so much emotion. Also, sorry Brazil 😉

Testing our latest voting equipment in New Hampshire today. So proud of what we've built at @voting.works. A robust tabulator, built on a secure foundation, and fully open source.

Checking out a Shoup lever machine in Topeka, Kansas. No, these are not in use anymore. Just fun to see in person the type of voting machine that was broadly used in the US in the middle of the 20th century.

Look I'm biased, but this NYT summary of Robert Redford in Sneakers feels way off the mark.
Text excerpt from NYT:

"Sneakers, a breezy caper starring Mr. Redford as a security hacker, reflected his occasional willingness to embrace popcorn cinema."

Then comes the most interesting part of the system: results reporting. The machines each print a tally report at the end of the night. The report includes a QR code that encodes the results data. www.washingtonpost.com/world/2024/0...

It's local election day in New Hampshire, and @voting.works is powering elections in 40 towns. Up from 5 towns last year at this time. Exciting to get open-source voting machines to more and more Americans!

How does Germany count ballots so quickly by hand? Because this is their ballot. Two questions. That's it. It takes longer for Germany to count than France, because in France it's *one* question. We use machines to count in the US because we have 30, 40, 50, sometimes 80 questions per ballot.
