You make meaning through the doing

If I would pay right now for a feature in Java, it is going to be type name alias; in situations when they are types with same name from different packages. Say, ``` type ShortName = com.blah.blah.blah.MyType ```

I had someone stop by my desk, and ask me with awe “are you coding? Why are you not using AI?” It’s the brave new world we live in now.

Hot take: IDEs and tooling not catching up with Scala 3 features does not bother me. They will catch up sooner or later.

I don't normally post my email newsletter, but I thought this one was a banger: on the dualities between constructor injection, the reader monad, comonads, and effect handlers. If that sounds like your jam: buttondown.com/functionalpr... (Or just grab the book! functionalprogrammingstrategies.com)

I don’t want to review the code AI writes instead I want AI to review the code I write.

The Builder Macro blog.rhetoricalmusings.com/posts/builde...

Enjoy this multi-part series on builder pattern in Scala. Intro to Builder Pattern blog.rhetoricalmusings.com/posts/builder1 Know Your Limitations blog.rhetoricalmusings.com/posts/builder2 Errors Are UX Too blog.rhetoricalmusings.com/posts/builder3

Dear friend, Morgen Peschke, dives to the depths of the builder pattern in this multi-part guest series on my blog: blog.rhetoricalmusings.com/posts/builde... Give it a read, it's good stuff!

In Scala, if you like the builder pattern, you can ensure the build method is available only when all mandatory fields are populated, though it involves a lot of boilerplate. #scala blog.rhetoricalmusings.com/posts/builde...

Scala Times Issue #599 - scalatimes.com/54dc2dfa62

@scalabridgelondon.bsky.social is back in October! Here's the projects we'll be working on: www.scalabridgelondon.org/projects/ Sign up for your choice here: docs.google.com/forms/d/e/1F... (All the details and much more on our website www.scalabridgelondon.org)

There's a good chance you have already used contramap (e.g. when creating a Circe encoder), but understanding the concept can be challenging. This article explains it using a practical example. #scala blog.rhetoricalmusings.com/posts/contra...

The static type of this type is dynamic - Anders Hejlsberg (Nostalgic C# 4 days)

I'm giving this workshop at Scala Days, which will cover most of the techniques I've learned over the last 15 years of building software in typed FP. Happy to answer any questions about the workshop (which will draw from the book I'm writing: scalawithcats.com)

Fantastic discussion, lot of great points. Thank you @rockthejvm.com and @runarorama.bsky.social www.youtube.com/watch?v=kK4v...

I don’t understand anything I can’t build - Richard Feyman Very true for a lot of engineers!

Alright, it’s my turn! Scala 3.7.0 released! 🚀 scala-lang.org/news/3.7.0/

Last night's @scalabridgelondon.bsky.social's session was lots of fun, working with @hktpe.bsky.social on github.com/creativescal... Come along and join us if you want to learn or improve your Scala-foo with interesting projects

But it’s a key!

First they preached OOP now they have started preaching DOP (data oriented programming), which I feel is such a cringe term.

Fantastic Scalar 2025 talk by @noelwelsh.bsky.social is up! Tagless final for humans: youtu.be/nyMwp7--rY4

Agentic code editing vs thinking and resolving the problem … they are not same.

I am mad that @intellij does not list Scala 3 updates in the list 😀

Named tuples in Scala FTW. Tempted to ditch case classes 😀

Just added slides for my talk "Tagless Final for Humans" to my page of talks: noelwelsh.com/landing/talks/ I gave this talk today at @scalar-conf.com. The core is a new encoding for tagless final in Scala, which makes much better use of Scala's features than the standard encoding.

TIL you can do .match like chaining as opposed match keyword in Scala 3
