  • GitHub repo Apache Spark

    Apache Spark - A unified analytics engine for large-scale data processing

    Project mention: Hi we have a stranege error while moving to spark 3.0.2 | reddit.com/r/apachespark | 2021-05-07

    Checking the code that seems to throw this error (here) this seems to hint at having some form of column name repeated. It may be an internal issue, and that you are reusing a name that is already present in one of the base tables, for instance. It's hard to know with the rewritten query you provide, since you may have rewritten it "correctly", also, the error could actually be propagated from some naming before, since this is a whole plan rewrite stage after all.

  • GitHub repo Apache Kafka

    Mirror of Apache Kafka

    Project mention: Look ma, no Zookeeper | dev.to | 2021-05-03

    The day has now come with the introduction of Kafka 2.8 which gives us preview of Kafka without Zookeeper. *Please be aware that this feature is not intended to be used in production, Kafka team is still working on putting some missing pieces of the puzzle.

  • GitHub repo scala

    Project mention: Java Is Criminally Underhyped | news.ycombinator.com | 2021-04-15

    - Scala: https://www.scala-lang.org/

    Java just doesn't have the cool factor that other languages have. A little rebranding could go a long way to reinvigorating the language in the eyes of newcomers. And I say that because the author of this blog post is a newcomer. Experiened developers know that, despite the ugly Oracle branding, Java is a good language with a sophisticated ecosystem of tools surrounding it. He seems to be mostly enamored with the developer experience of IntelliJ + Java + Maven. And while it is great, that experience is possible with most programming languages.

    Disclaimer: I haven't used Java since my early University classes 10+ years ago.

    Project mention: What is the state of frameworks and libraries support to build microservices in scala? | reddit.com/r/scala | 2021-04-16

    Project mention: What backend programming language do you recommend? | reddit.com/r/learnprogramming | 2021-05-11

    So, i want to build real time web apps like lichess.org, a video chat web app and so on. So i tried java (spring boot), because it's high in demand and very popular, but i felt like very messy with dependecies, frameworks and etc. Then I tried Go, which I like because it's simple, easy and fast. I tried php too, and i liked too. And i tried to learn C++, and i think it's very very cool and easy.

  • GitHub repo Scalaz

    Principled Functional Programming in Scala

    Project mention: In Search of the Best Functional Programming Back-End: 2021 Update | dev.to | 2021-01-24

    I’ve specifically had 2 job offers internally at my company because of this language. First with Cats and Scalaz and now with ZIO, Scala has taken the best parts of Haskell, the best parts of Scala, and made it really nice to work with. You can barely see the OOP leftovers.

    Your favorite language gets closer to bare metal.

    Project mention: Why Scala (still) hasn't missed the Android opportunity | reddit.com/r/scala | 2021-03-24

    It can be challenging to exchange ideas between the left and the right side of a brain, so sometimes you might not get the outcome you are hoping for. Is this the PR in question? Add support for 32-bit platforms through a linker-level switch by shadaj · Pull Request #1571 · scala-native/scala-native (github.com) I personally see no reason why SN should not be able to target wasm, especially as the target is LLVM, but..
