Great thread. Thanks for sharing! It's interesting to me that the author feels that things were great with Uber in 2016 pre-Trump and that Trump's election was the catalyst for the negative sentiment. Susan Fowler's famous

Why dumb? Admittedly I don't like the common phrasing of "pick 2". I much prefer: "in the face of a partition, a system can be consistent or available, but not both."

All of those things are very different though. It’s possible you could be excellent at predicting Senate races and terrible at the electoral college, right? And you only get one data point every 4 years.

What does it mean to predict the probability of an event that can only possibly be tested once? Isn’t the prediction unfalsifiable?

Is aviation actually an example of what you’re describing? Airlines do have legal liability in the event of crashes and it’s the NTSB that investigates.

I don’t know the original context, but I take a quote like that to be a reminder that there’s cost to preparation and you could go overboard.

Suppose you test a population of 100 people in which 10 are infected. The coin flip test reports 50 people infected on average. Among those positive tests, at least 40 have to be to be false positives Because there are only 10 infected to b

A coin flip won’t be nearly 50% accurate.

Is there data about that? Growing up in the 90s I thought we could usually by something for less than the MSRP. When I watched the show in the 90s I always felt the actual prices were high.

There may be complexity under the hood (I don't know), but in my experience, even pretty advanced users employ a pretty straightforward mental model that's considerably simpler than the commands themselves are to use.

What a disappointing and disingenuous piece. To take an egregious example, the article points out that 90% of fires aren’t caused by electrical equipment, but fails to mention that the most destructive ones have been. As for the idea of hom

Is the implication that every library module with async code must be rewritten to use promises or else be obsolete?

I can see that. I've really only worked with a few workloads where this behavior was quite bad. (In particular, the out-of-the-box policy to vacuum when the dead tuple fraction reaches 20% means that for an INSERT-mostly workload wit

I'm not sure why this comment is downvoted. The behavior of PostgreSQL on workloads that require vacuuming of large tables -- and especially the default behavior in that case -- is hugely problematic. There's a major project ong

If one already accepts that the object should be dynamically allocated because otherwise it's too easy to accidentally copy (which seems specious, but that was the suggestion), then all of those arguments apply to that recommendation,

Solid gold. I just commented elsewhere about the gumption trap chapter, but the whole chapter this passage comes from is similarly insightful -- maybe more so.
