I just tried Slack AI, and it’s arguably the best use case for LLMs I’ve seen in a SaaS product. Look at this summary: 👇 Does MS Teams have the same feature?

Now it's official! 🎉 Go read the whole announcement 👇

Scala 3.8 released!

#scala

Hey, Scala early adopters! 🚀 Version 3.8.1 is technically out, but let's wait until everything is officially settled and announced, okay? The upgrade is huge, so it's completely understandable that there might be some minor linkage problems. 🛠️ #scala

🚨 Scala 3.8 deprecates `-Xfatal-warnings` in favor of `-Werror`. Be aware if you rely on `sbt-tpolecat` or `typelevel/scalac-options`, as they need to update their default flag sets.🚩 The fix is already in progress 👇

Deprecate -Xfatal-warnings option for Scala 3.8+ by EnviousSwan · Pull Request #225 · typelevel/scalac-options

Closes #219 Getting this error with Scala 3.8.0 and sbt-tpolecat 0.5.2 [warn] Option -Xfatal-warnings is a deprecated alias: use -Werror instead [...

#scala

The first thing that hits you when starting with Go: "Wait, how do I implement this interface?" Well, you can't. Not explicitly. Go's philosophy is: If you walk like a Duck and quack like a Duck, the compiler just assumes you are a Duck. 🦆 #golang

Java doesn't support Higher Kinded Types. But with enough determination, boilerplate and type gymnastics, you can technically emulate them. 🤸‍♂️ #Java #Scala

Higher Kinded Types with Java and Scala

In this post we will see how Higher Kinded Types types can help increase the flexibility of our code and reduce duplication.

Typeclasses in Java are taking shape! 🏗️ The first experiments have been merged, moving this from theory to reality! #java

This feature in Scala 3.8 is so experimental that it doesn't even have a SIP yet! 😀 I hope I don't need to explain the code, but be warned: exhaustivity checking is currently broken for this 👇 #Scala

The last missing piece? 🧩 @Zed is finishing up a native Git Graph and it looks incredible! 🤩

Next on the list of Scala 3.8 experimental features: Flexible Varargs. Until now, passing multiple collections to a varargs method required manual concatenation. With this change, you can mix multiple splices and single arguments freely ✨#scala

How to access method default parameters via macro? 🧐 Pretty niche topic, but after reading you will learn: ✅ How some JVM internals work ✅ What the Selectable trait is ✅ About the transparent keyword

I've started working on a project in Go - who would have expected that? 🤷 I'm treating it as a personal challenge. Sometimes you have to lose something to understand its value. #golang #scala

Scala 3.8 will bring several experimental features. One of them is the relaxed lambda syntax, where you don't need to put a newline after the colon. Haters of the braceless syntax will hate it even more! 😀 #scala

Hey, Java devs! If you're on JDK 17+, it's time to start using Sealed Classes to eliminate invalid states. On JDK 21+, combine them with Pattern Matching for a truly powerful result. The difference in conciseness and safety is incredible! 🚀 #java

This is a follow-up to the previous article about builder type gymnastics. This time, all the boilerplate code is hidden behind the macro. Sadly, under the Scala 2 macro 😐 #scala

The Builder Macro

Some astute readers of the previous post on builder pattern highlighted the verbosity of the pattern. The builder pattern is a powerful pattern but...

I played around with the new procedural SQL in Spark 4. It's wild. I like it. You'll probably hate it! 😀 #spark

Apache Spark / Procedural SQL

Apache Spark 4.0 introduces a significant enhancement to its SQL capabilities: experimental support for procedural language.

The SBT plugin absolutely no one asked for... but I built it anyway. 🤷‍♂️ You can now use HOCON files for your build configuration. It’s surprisingly clean. I’d love to hear your opinions 🙏 #scala
