It's funny that we say "in lieu of" instead of "in place of" given that "lieu" is French for "place". I guess we're saving a letter?

One of the things I learned from this podcast with Patrick McKenzie is that signing your name when paying with a credit card is a commitment mechanism, not a security mechanism. It's a written version of swearing an oath to pay the debt you are incurring.

Sometimes I think we could use some further ado.

    Anybody out there using Azure Cosmos DB? Sounds like interesting tech, but I never hear refs to it in the wild.

    Reading this piece by @profmusgrave , the thought that popped into my head was: You need the technical skills to actually get that tech job. But, to have real impact at that job, you need social science skills.

    And you don’t even have to know how it works* to use it!

    • (Unless, of course, something goes wrong. Then, you really need to know how it works to fix things.)

    I don't care about MTTR, I care about TCI (total cost of incidents).

    In particular, I think the authors miss the risk of automated mitigation approaches creating new failure modes.

    It’s not rational, and I can’t explain why, but the Unix systems companies like DEC, Sun Microsystems, and SGI felt always gave me a “cooler” vibe than the cloud giants (Amazon, Google, Microsoft). Must just be when I came of age.

    “Accidents are almost always the result of rare combinations of normal performance variability and chance combinations of unlikely events.” – https://training.nwcg.gov/courses/UOHTML/Intro_Facilitated_Learning_Analysis/external/265/2015%20FLA%20Guide%20JanuaryFINAL.pdf

    "Human error is the attributed cause of large system accidents because human performance in these complex systems is so good. Failures of these systems are, by almost any measure, rare and unusual events. Most of the system operations go smoothly; incidents that occur do not usually lead to bad outcomes. These systems have come to be regarded as 'safe' by design rather than by control."

    – R.I. Cook, D.D. Woods, Operating at the Sharp End: The Complexity of Human Error
