READING

Scala's great ecosystem

I need to shout out to those people in tech who make my life so much easier: the creators of Scala and especially its great ecosystem, in particular ZIO, caliban and http4s.

What Can Scala Learn from Rust?

In this talk, the author of ZIO explores the evolving landscape of programming languages, with a focus on Scala and Rust. He discusses Scala's journey, its position amidst emerging languages like Rust, and the impact of Scala 3 on functional programming. John reflects on some of his recent experiences with the Rust programming language, pinpointing what Scala can adopt from Rust's strengths and weaknesses to enhance its own ecosystem.

RELEASES

Sample Scala 3 / Quarkus application

This project is quickstart using Scala 3 and Quarkus, the Supersonic Subatomic Java Framework.
Carlos Eduardo (@carlosedp)
Spark NLP 5.2.0

Introducing a Zero-Shot Image Classification by CLIP, ONNX support for T5, Marian, and CamemBERT, a new Text Splitter annotator, Over 8000 state-of-the-art Transformer Models in ONNX, bug fixes, and more!
Spark NLP contributors
caliban 2.5.0

This release brings an incredible amount of performance improvements, some major library upgrades (zio-http, Play) as well as some powerful new derivation abilities such as deriving fields from case class methods.
caliban contributors
ducktape 0.2.0-M2

The 0.2.x series comes with a lot of improvements, some of them being: support for configurations for nested transformations (previously these would need to be their own Transformer instance, no matter how basic the config was), the library now reports all of the transformation errors all at once.
