    Been waiting for this since midnight on 1/1!

    my guess is that other factors, like scheduling delays, dominate in this case and contribute to potentially significant variance before a leader realizes what’s up. Putting the clock check on the critical path mitigates this at the expense of lots of clock checks.

    One of the classic examples is leader failover: when is it safe for a replica to start serving? We only have to wait to be sure the original leader had realised it’s stopped getting heartbeats. So theoretically a tighter clock sync makes that wait time shorter. But...

    This paper that improves clock synchronization accuracy to tens of nanoseconds is amazing work. What changes with that level of accuracy? Like the paper says, Spanner commit times get a lot shorter. But is it now safe to take action without coordination?

    cool, asked my wife verbally about changing brands away from windex this morning and now this is in my timeline, cool.

    Context: I am reading Accelerate and want to understand what it’s actually telling me, but there’s a level of statistical sophistication required that I don’t have.

    Can anyone ELI5 what partial least squares tests actually show between the observed and predicted variables? Is it a necessary-and-sufficient relationship or something else?

    Just straight up ordered fish and chips from a food truck in San Francisco. Because I am a Basic Brit.

    This is trivial if you follow my approach, which is to carefully and meticulously disappoint everyone all the time.

    2019 version of the same question: what technical (soft or ‘hard’ skills equally relevant this time) book published in the last year or so would you recommend to everyone? Slack still has the professional development funds, we’re still hiring!

    This is such a great tip. Also echoed by Jeff Dean at Google when a group of black and brown software engineers asked him how he seems to keep up with the torrent of ML research: You can't read 50 papers a day. But you can read 50 abstracts, and then read a few deeply.

    for a discipline that places emphasis on ‘blamelessness’ and so on, there sure is a lot of snarky content from the resilience engineering community telling us how we’re all doing everything wrong

    I see this and raise “leaving the country without your green card”, which is easy to do but crucially means you can’t get back in.
