It's funny, I had the same conversation with my colleague about those differences a couple of days ago. 😀 Great article by the way! #scala https://alexn.org/blog/2025/04/02/tagged-vs-untagged-unions-in-scala/
Managing mutable state concurrently on the JVM can be tricky. cats.effect.Ref simplifies this significantly with atomic, functional guarantees. Excellent intro to the topic by nostr:npub1fsvdwzhywlxc6gxp99g2c4g9aydyhlaamw2jhs6ajpnxts8nyv4sswy05d 👇 https://blog.softwaremill.com/cats-concurrency-basics-with-ref-and-deferred-399e0335630

It looks like the new QUERY http method is ready to be implemented! It enables safe retrieval by putting query information (e.g. in JSON) directly into the request body instead of the URL. #http https://datatracker.ietf.org/doc/draft-ietf-httpbis-cache-groups/
If you work with DynamoDB, do you know the difference between a filtered scan and a query operation? Understanding this distinction is crucial for optimizing performance and cost. 💰 #dynamodb 👉 https://youtu.be/U-yApJ2_FCE
Daniel rocks! After just two weeks, another interview is live! This time, James Ward discusses effect systems, how they help to make illegal states unrepresentable and more! 🤘#scala https://youtu.be/M8DuVYnsW5A
What a nice application of Scala 3's match types! #scala https://mercurievv.github.io/minuscles/readme.html
Kyo is getting closer to a stable release.

"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 nostr:note1t5fjf6alrxvyhgcmfw9yjrpjfz6e87572f370hsh5qs0gx5telvqqd3f0w

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. nostr:note10kajftjz5ud8xz62p9vncrra0denuklwt29c5a7t8tx3mtuh07yqetrz0v

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/
