    Fortunately, Uber made tooling for languages with broken type systems

  • My Thoughts on “Bad Code”

    Some patterns arise from language design

    * You can't express `T` where `null` is forbidden in the type system so you get NullPointerException everywhere and defensive null checks.

    * You express a sum type as a product type because your language does not have sum types .

    * Your language doesn't have first class multiple return values (or tuples) so you return extra parameters via out parameters or thread local variables such as `errno`.

    * Your language doesn't have exceptions (or algebraic effects) and can't do IO so you have monad transformers.

    * Your language doesn't have set-theoretic types so you need hacks like `thiserror` .

    * Your language doesn't have stackful coroutines or can't infer async IO for you so you have `async/await` spam or callback hell or "mono's".

    * Your language doesn't have exhaustive checks (or pattern matching) so you need a fallthrough case check on switch statements .

    * Your language doesn't have algebraic effects, so you need to pass context everywhere.

    I know someone will reply about Java's null annotation checking options, so here is one of them: https://github.com/uber/NullAway .

  • How to use Java Records
    3 projects | dev.to | 18 Nov 2022
    A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:
