   This is a really interesting read, and as someone who’s almost exclusively programmed in high level languages, this approach seems alien to me. A couple of questions: 1. Is it possible to write complex, modern applications (things like brow

   I agree. Doesn’t FB also agree, and hasn’t it already disabled that kind of API access? At least when I tried to get access to friends-of-friends info for an app I was working on a couple of years ago, there was no way to request it.

   Reading through that article, the FB lawyer’s argument is pretty reasonable: > I go into a classroom and invite a hundred friends. This courtroom. I invite a hundred friends, I rent out the courtroom, and I have a party. And I disclose —

   I think it’s reasonable to expect engineers to be able to learn how .reduce works. It’s part of JavaScript, after all. If a new hire doesn’t know (a junior dev, or someone without experience in JS/Scala/etc.), an hour of reading p

   I read over the page twice, and didn’t see an actual study linked. Does someone have a link to the PDF? And was this actually published in a peer reviewed journal?

    I mean, I can: 1. Invest in an index fund, which I deposit into automatically every month, at X% return and Y% risk. 2. Invest in a rental property, which I then have to spend time to manage (or pay someone to manage), at the same X% return

    Still reading, but is that factoring in the labor and opportunity cost of managing a rental property?

    Any more details on how the encoding worked? Was this just a substitution cypher with some gibberish sprinkled in?

    Facebook shows ads, but it’s not fair to say that it sells user information. Working in ad tech, there are tons of companies that actually sell use information — it’s a different business model.

    Andy Grove talks about this in his excellent High Output Management, where he asks the question: how should knowledge managers (senior ICs) and people managers spend their time? His answer is: on high leverage activities. Instead of fixing

    Maybe what John is getting at is while a Principal can do that for a while, at some point their tech chops will get out of date and rusty, both in terms of industry knowledge and the company’s internal stack and best practices. At that poin

    tl;dr- 1. Larger tests are more flaky 2. Choice of tech has additional, minor contributions to flakiness (eg. unit tests vs. webdriver vs. Android emulator)

    Agreed. But if F#’s pipe operator makes it to Hack and JavaScript, null chaining makes it to C#, CoffeeScript, and JavaScript, value types make it to Haskell, Clojure, and JS, etc.. Eventually the overlap between different languages’ featur

    I don’t know, it just feels like a bit of a boring world if every language looks the same, instead of prodding you to look at the world from a slightly different angle.

    Since everyone is coming from different language backgrounds, I wonder if it’s better to treat JS/WASM as a low-level compile target, and simply compile peoples’ language of choice to JS (OCaml via Bucklescript, Scala via ScalaJS, Hask

    As an aside, I’m not seeing any novel features in this list. All of them seem to be borrowed from other languages (Swift, F#, Haskell, ...). With enough of this, at what point will all languages start to look identical (Youngme Moon calls t

    I’ve migrated a pretty big codebase to TS, and then again to noImplictAny. One suggestion is to turn the flag on, migrate a few files, then turn it back off. When you’ve migrated a decent number of files, turn it on everywhere. For a really
