I have a special place in my heart for F#. While I do a lot of Scala these days, professionally and open source, F# was my first introduction to functional programming that eventually got me into Scala. F# and Scala are extremely similar la

Being SVG also means you can style them via CSS, allowing simple interactivity. For example, you can make graph edges change color or become thicker when you mouse over them, making it easier to follow edges in a large messy graph

I use Graphviz throughout my book https://www.handsonscala.com to render diagrams. I honestly think it looks pretty good: - Dependency graph between chapters in the book: https://www.handsonscala.com/chapter-1-ha

Futures and Actors are complementary tools, and neither is really a substitute for the other. `Chapter 16: Message-based Parallelism with Actors` has a good discussion of when you would use each one, and some of the exercises involve using

The book is basically done for now. I will likely update it for Scala 3, but that's still a moving target, so I'll wait for the dust to settle before considering it. I don't expect the code to need to change too much to suppo

It will, but the Scala3 launch date is still up in the air so I can’t give any concrete promises as to when

I think Scala adoption is doing great. A lot of the initial hype around things like Akka and Pure Functional Programming has died down since the frothy excitement of 2015-2016, but honestly I think a lot of that hype was oversold and many o

Trying to make Scala better for "simple" projects is definitely a focus of this book. You are right that traditionally the fixed overhead of learning Scala made it only worth it for huge and complex projects, but this book introdu

I'm planning on open sourcing the build pipeline soon, but it's basically a Mill ( http://lihaoyi.com/mill ) build pipeline which uses Scalatags + CommonMark-Java + Puppeteer + ApachePDFBox + EPubLib + kindlegen to

I wouldn't call pure functional Scala a dead-end, but it's definitely a niche that not everyone will be comfortable with. For those that enjoy it it works great, but this book is intended to promote a style of programming that is

If you're interested in Actors, the book has a chapter `Chapter 16: Message-based Parallelism with Actors` that does an introduction to them, and they are used "in anger" in `Chapter 18: Building a Real-time File Synchronizer

The book's web page makes this pitch: Python-like convenience with Go-like performance, easy safety and correctness via compiler checks, and a huge ecosystem of tools and libraries. Compilation time is definitely a tradeoff, but if any

Glad you like the typesetting! I’m a professional web developer, among other things, and the typesetting is just HTML + Bootstrap CSS 4.4.1, rendered into PDFs using Puppeteer. Turned out looking much better than I had hoped!

This was posted once before when it was work in progress, I thought it would be nice to put it up again now that it is complete :) In one 400 page book, Hands-on Scala takes you from from FizzBuzz, to Sudoku solving, to Websites and API ser
