    1/ The team has been working around the clock for the last week to support the State of Georgia in running their first state-wide risk-limiting audit, which turned into a full hand-count.

    We just wrapped up our work supporting Georgia with their post-election audit. Because of the tight margin, this audit turned into the largest hand-count in US history.

    Throw away all the self help and advice books. Everything you need in 6 tweets from a 5yo.

    When talking about our agendas for the day, I told my 5yo I was a little nervous about a meeting I have today. He said, “Mama, I am nervous all the time. I know what to do.” So friends, here is all the advice he could fit into the drive to school:

    A candidate we interviewed and turned down sent us 2 pages of very thoughtful feedback, some positive, some negative, on our interview process. Amazing. Thank you.

    Viewing source on Wordle is totally fine, but it's neither hacking nor is it playing Wordle. A little like peeking when playing hide and seek.

    Correct. Pets on zoom, please, pretty please.

    I am worried we've reached the stage of the pandemic where you think I do not want to see your pets on Zoom. That is entirely wrong. Show me the dog/cat/rogue gerbil.

    This is kind of important. Feels like the test instructions should be particularly clear about this.

    Did You Know: When you swab your nose for a rapid test or a PCR test…. You do NOT want to go for the “snot and gooey” stuff. Nope, the virus lives in the cells lining your nose. You want the swab to rub against and “scrape” the cells of the nasal walls for the best sample.

    Thinking about this some more... It's easy for a software engineer to find today's / tomorrow's / all the Wordle answers. The game wasn't built to withstand serious attack. It's always interesting to see what some choose to do with their skills. Like ruining people's fun.

    Yep yep yep.

    People love the open web because they know they can have agency & control over the experience, and they know it’s still a place where people make things that have heart & soul. Even if they can’t articulate it, they can just tell.

    Excellent set of questions.

    Give yourself full permission to interview your future managers back. When they ask "Do you have any questions for me," take the opportunity to expose what your next 1+ years under this person might be like. Here are 5 questions I have or wished I'd asked of my future managers:

    I'm still thinking about The Alpinist, which I watched a few weeks ago. Mind blowing.

    Whatever you think about NFTs, you cannot deny this truth.

    I still think "nonfungible" sounds like it means "cannot be turned into a mushroom".

    This retro on the Roblox outage is fascinating, and one critical lesson is there were multiple causes. Complex systems fail in complex ways, and that means almost always more than one root cause.

    As we continue to struggle with COVID, it's easy to miss the tremendous scientific work over decades that gave us the vaccines. This piece from a few days ago is really inspiring.

    Many poo-poo'ed exposure notifications. But bottom line: - many have installed it - notifications work - the apps are now improved with self reporting - privacy architecture remains very solid When deployed judiciously, tech can do a lot of good with low risk.

    Over 16M people have enabled on their smartphones, and users can now self-attest to launch anonymous exposure notification! 🦠📲 Have you received a exposure notification alert yet?

    One more interesting aspect: giving your name and address to the USPS is roughly zero incremental privacy risk. This is a very nice added touch.

    ✅ Dead simple form ✅ Likely reuses existing address validation and checkout flow from and shipping integration with USPS ✅ Fast and responsive on day 1. 👏👏👏 Way to go!

    As an NBA fan, I certainly wouldn't mind if this mess kicked off the more important conversation we've all been waiting for.
