      Vaughn Vernon Retweeted Gary Bernhardt

      Minus the formal calculus, I've been saying this for ages. Programmers invent their own complexity, which is always unnecessary, and often accidental. But accidental is because they don't understand the problem well enough.https://twitter.com/garybernhardt/status/982823194846420992?s=19 …

      Gary Bernhardt @garybernhardt
      My favorite reason to learn a bit about the lambda calculus: it shows us 1) how simple computation is (at first it seems too simple to compute anything "real"); and 2) all of our programming complexity is invented by us (for reasons both good and bad). https://mobile.twitter.com/snowpolar/status/982673251821240322 …

      This is the worst when a programmer thinks it makes them look smarter than everyone else. I have zero tolerance for this attitude. It's the path to project failure, and when I have the choice I would terminate that programmer. Sadly few managers understand this.

      It is also subjective. I once had a team lead that get unhappy with me because I used map, filter, reduce. I honestly felt it wasn't anything complex and make things cleaner

      Vaughn Vernon Retweeted Jon Pretty

      I saw this very opinionated tweet the other day, which to me read like "my goal is to fit in." I also concluded that his suggested code was obscure. Read the replies and see what the consensus is.https://twitter.com/propensive/status/981805791228387328?s=19 …

      Vaughn Vernon added,

      Stop using, opt match { case Some(x) => f(x); case None => y } Stop using, http://opt.map (f).getOrElse(y) Use, opt.fold(y)(f) I feel like I'm very late to this party.

      I failed to make my tone clear in that tweet. The intended interpretation was that you *can* stop using the two longer forms because there's a more concise version available that you might not know about; not that you *must*. I can appreciate there is variety of opinions on this.
