ChatGPTはプログラミング言語マスター（語弊ありまくり） - kmizuの日記
皆さんおはようございます。見ている人は見ていたかもしれませんが、昨夜はかなり遅くまで巷で話題沸騰のChatGPTによくわからんクエリを投げて、その結果をみてげらげら笑っていました。特に存在しないプログラミング言語であり「ScalaにHaskellと同じ型推論を加えた」言語Scalayがあることにしたら、ChatGPTが本当にHaskellぽい（単なるHMでなく、Haskellぽいというのは型クラスまで推論される辺り）型推論を持つ架空のScalayコードを解釈実行してくれたりしたところは、控えめに言っても予想外の結果で深夜なのに部屋で忍び笑いをしていました。 Scalaに引数の型推論を追加したようなパチもんのプログラミング言語Scalay（仮）ができてしまった（ChatGPTと対話してる間だけの短い命）。 一応、add: (Int, Int) => Int が推論されてるのすばらですね。 p
Scala Center at EPFL
Let's improve Scala together. The Scala Center seeks to: Coordinate and direct the open source development of libraries/tools of broad benefit to the community. Substantially grow our community of open source contributors. Improve the landscape of Scala's libraries. Provide scaffolding to help the community develop, publish, find, and evaluate Scala libraries. We'll start by consulting with the us
Scala Functions vs Methods
Scala has both functions and methods. Most of the time we can ignore this distinction, but sometimes we have to deal with the fact that they are not quite the same thing. In my Scala Syntax Primer I mention that I use the terms method and function interchangeably in the discussion. This is a simplification. In many situations, you can ignore the difference between functions and methods and just th
Spotify Scio - Google Dataflow の Scala言語版 - Qiita
Google GCP(Google版AWS)のDataflowサービスを使ってみました。 Dataflowとは、その名の通り、膨大なデータをGoogleご自慢の分散環境を使用して並列で爆速処理してくれる、ビッグクエリーと同じGCPのマネージドサービスの１つです。 使用できるオフィシャルなプログラミング言語は、JavaとPythonのみですが、 Spotifyから、ScioというScalaのライブラリが提供されていますので今回使用してみました。 Dataflowでは、パイプラインを作成し、入力、変換1、変換2...変換N、出力の３ステップで構成します。関数型言語のScalaは、変換ロジックをラムダ式でコンパクトに記述できるため、Javaよりもコード量が少なくて済みます。 Spotifyでは、KafkaからDataflowへ移行する際に、Scalaで記述できるようにScioライブラリを開発した
Apache Kafka - Wikipedia
Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. Kafka can connect to external systems (for data import/export) via Kafka Connect, and provides the Kafka Streams li

Put resources on compiler classpath · Issue #1965 · sbt/sbt
Adding a "compile"-scoped dependency to a subproject puts the dependent classes not only on the source path of scalac but also on the class path so that macros can be found. But this only works for classes, not for resources, e.g. reference.conf for Typesafe config. sbt should treat resources the same as classes for the compiler classpath, like in other dependency management scenarios. Here's a br
Add strict aggregation from sbt-doge to SBT 1.0 · Issue #3698 · sbt/sbt
I'm trying to migrate from sbt-doge to SBT 1.0, but I can't find a way to replace strict aggregation (+++). Using it seems to be the only way to build a project for a specific version (a thing usually done in Travis builds) in typical setups of a root project aggregating all sub-projects. I think that the default behavior of ++ should be to do strict aggregation as I find it difficult to imagine a
copy resources directory BEFORE compiling · Issue #3934 · sbt/sbt
Although sbt adds the target directory to the classpath of the compiler, this causes problems if the compiler needs access to resources because they are only copied AFTER (or in parallel with) the compile. Therefore you can get a situation where compile fails the first time, then succeeds. To avoid this, I recommend that resources are copied BEFORE compilation. Original report below, which slightl
