I used to think LLMs would make #Python and other mainstream languages dominate forever. But if AI is writing the code, you don't need a language just because it's easy for beginners or hiring. You don't even need to fear refactoring anymore.
What you really need is a language that catches the AI's mistakes. You need strong compilers and strict types (like #Rust or #Scala) to act as safety nets when the AI messes up.
This article changed my perspective 👇

If you're a fan of Tapir, you'll want to see how ZIO (natively) handles type-driven http endpoints, OpenAPI generation, codecs etc. #scala https://youtu.be/ea_CkgJ-tl4

Great interview with Jonas Bonér covering Akka's history, core concepts (Actors, Streams, Persistence), the shift to BSL, and its role in AgenticAI. #akka #scala https://youtu.be/wXM3-jAKDfQ

After experimenting with @Zed a couple of months ago, I have now finally ditched @IntellijJ for good. And it's awesome! So awesome that I need to share it with you, sorry 😂

"Scala can be incredibly productive… if we stop using abstractions that offer no value!" @@noelwelsh Really looking forward to watching this talk when it becomes generally available. #scala https://noelwelsh.com/talks/tagless-final-for-humans https://cdn.nostrcheck.me/f5c3f597f754f534d47b0be2b9afe263894ecdad3d639453c4abc31f40db2c23/82eaa89328103df6e4587ea338e9f11f31467baa69d272b696bf5c1db64f4cf5.webp https://cdn.nostrcheck.me/f5c3f597f754f534d47b0be2b9afe263894ecdad3d639453c4abc31f40db2c23/eacbc62634265476c2a3c661d7bf1f16d7443952285b3dea97e363ed7e055dbe.webp

A new Metals release adds a useful automatic import optimization feature. For instance, if you type Future.successful(...), only the Scala Future will be suggested, as the Java Future has no such method. #scala http://scalameta.org/metals/blog/2025/03/26/strontium/

I've updated the fs2-rabbit lib, in case anyone uses it besides us 😀 #scala https://github.com/profunktor/fs2-rabbit/releases/tag/v5.4.2 #note1t5f…3f0w

Use a global sequence implemented via inheritance instead of separate auto-incremented ID fields. 👇 #postgres https://www.cybertec-postgresql.com/en/debugging-postgresql-more-easily/

Have you already upgraded to the latest version of Cats Effect with the improved scheduler? Any observations so far? #scala https://github.com/typelevel/cats-effect/releases/tag/v3.6.0

I would really like to see a type-safe equals operator that works without derivation (e.g., Dog == Dog should compile, but Cat == Dog should not). It's not just a weak point in conditional pattern matching, I would say it's a major vulnerability. https://scala-lang.org/blog/2025/03/24/evolving-scala.html

It's comforting to hear that even great programmers had moments in their lives when they doubted they were good enough to become programmers. I definitely had those moments myself, in high school and then later when I started with Scala. #note10ka…rz0v

Great read on debugging a Postgres performance mystery. You will learn a lot about Postgres internals just by following the author's thought process. (btw, what a grafana theme! 😀) #postgres https://blog.danslimmon.com/2025/03/14/did-u-ever-read-so-hard-u-accidentally-wrote/

SIP-62, aka better for loops, changes almost nothing from the outside, but it's probably the feature I'm looking forward to the most. Knowing how for loops are currently desugared just makes me sad. I don't like suboptimal code. #scala https://github.com/scala/scala3/releases/tag/3.7.0-RC1
