Top 15 Scala Libraries for Data Science in 2018

For your convenience, we have prepared a comprehensive overview of the most important libraries used to perform machine learning and Data Science tasks in Scala.

Static Sorting in Slick

When writing our project, we wanted to pass a static sorting object all the way through our stack from the API (where it was parsed automatically) to Slick, and have the database results be sorted automatically without any extra input from the end-user (ie you, the feature-developer).

Safe(r) mappings in Slick with Shapeless

A colleague asked me today if there’s any way to reduce the boilerplate around mapping common columns in data types and database tables; for example, the id column or created_at and updated_at. We’re using Slick, so this post will be based around that.

Tour of Akka Cluster - Cluster Sharding

In this article we are going to take a closer look at cluster sharding and then make use of it for our reactive payment processor.

Akka cluster on kubernetes. Traps and pitfalls

From architectural point of view clustering should not mess you by itself. It is still better for every service to have its own Akka cluster for more resilience following general microservice architechture.

Mill: Better Scala Builds

Mill is a new build tool for Scala: it compiles your Scala code, packages it, runs it, and caches things to avoid doing unnecessary work.

Assembly of Galaxies

This blog post aims at implementing N-body algorithm for simulating a galaxy assembly.

Top Link of February: Comparing Scala relational database access libraries

Relational databases might no longer be the only and primary storage option; but for sure, they aren't going anywhere. Accessing them is still a common task in our programming life, and that translates to many libraries which aim to help us write correct, readable and maintainable RDBMs-related code.

RELEASES

scala-logging 3.8.0

Added LoggerTakingImplicit, bugfixes.
scala-logging contributors
Akka 2.5.11

This version contains a fix for a regression introduced in Akka 2.5.10 which made rolling upgrades of an Akka Cluster from version 2.5.9 to 2.5.10 impossible.
Akka contributors
Kamon 1.1.0

Today we are announcing Kamon 1.1.0 with a couple bugfixes and a small but important improvement on context propagation, plus several minor updates on other modules that sort of went under the table for Akka, Akka Remote, Akka HTTP, Play Framework, Http4s and our sbt-aspectj-runner plugin.
