Thanks for the correction! 🙏 @birgitta410.bsky.social great piece!

It's hard to talk about what different AI tools and projects can do and where they fit. I found this article by @martinfowler.com very helpful for defining the terms to use: martinfowler.com/articles/har...

Just read martinfowler.com/bliki/Agenti... Setting up things like OpenClaw to access your email is not safe but there's something even worse about the whole "personal agents" hype: email becomes just another transport layer between agents. That's not something humans will want to engage with.

"Curated skills help smaller models punch above their weight class in terms of task completion. Anthropic's Claude Haiku 4.5 model with skills (27.7 percent) outperformed Haiku 4.5 without skills (11 percent) and also Claude Opus 4.5 without skills (22 percent)." www.theregister.com/software/202...

New Metals release is out! It includes support for stdio in the Metals MCP server, as well as a new way to decompile class files. Take a look at the features and bug fixes: scalameta.org/metals/blog...

Ever wonder why you can't just override #sbt settings in a task? They're immutable, but there's a workaround 👀 Wrote up a quick #TIL on using `Project.extract` to run tasks with custom settings. #Scala blog.michal.pawlik.dev/posts/til/sb...

Slides from our #ScalaDays talk with @kubukoz.mstdn.party.ap.brid.gy are out! polyvariant.github.io/are-you-tall... #Scala #Smithy4s

Here's one for all the game devs out there www.bloomberg.com/news/newslet...

Some time ago I made a presentation that wasn't recorded... But at least some of the points from it could be showcased with this gist gist.github.com/MateuszKubus...

If you're missing some feature in Chimney - contribute it! github.com/scalalandio/...

it is impossible to generate code comments from source code because good comments are definitionally based on things not in the source code (intent, counterfactuals, experiments, etc.)

Fantastic meetup yesterday! Shout out to the organizers and speakers for putting it all together. It was like looking into my CV: first job - Futures, next job - Actors, then monad transformers, and now tagless final. 😂

Functional #JVM Meetup in Prague 🇨🇿 was a blast! It was awesome to meet fellow #functional programmers and discuss #scala over great Czech beer 🍻

Pick your track! As always, we're giving you lots of incredible talks to choose from. But don't worry if some that you're interested in overlap - after the conference you get access to all recorded presentations. #lambdadays

The slides for both "Virtual Threads, 2 years later" and "What is Functional Programming" are available on my website: warski.org/talks/

Good morning @lambdadays.bsky.social! Today, together with @michal.pawlik.dev, we will go through the history of Scala: there will monads, transformers, actors, singers and the meaning of being in a startup! Come coin us in Track 2 @13:30!

🧭 Coming to #Lambda Days? We’ve got a handy Attendee Guide with local tips: where to eat, drink, chill, and explore in #Krakow! 👉https://ow.ly/P95M50VPxVn

🤣 CV driven presentation! Thanks for attending! We really enjoyed giving the talk to the wonderful crowd in Prague yesterday! Hope to see you soon again! 🇨🇿

Announcing Chimp: build type-safe, boilerplate-less #MCP servers in #Scala using the HTTP transport! Below is a self-contained, scala-cli runnable example:

The design is based on what @mplachta.com presented during @scalar-conf.com this year: www.youtube.com/watch?v=RWvT...

Flavours of Scala with @mplachta.com & @michal.pawlik.dev at #LambdaDays! 🌶️ Explore "better Java," #Haskell for humans, and more as they guide you through 2 decades of #Scala evolution. Spice up your coding style! 🔥 📅 12-13 June 2025 in Krakow, Poland! 🎟️ www.lambdadays.org

Model Contex Protocol coming soon to Metals for even better #Scala IDE experience. Give it a try!

With our new Scala MCP server we are able to eliminate hallucinations and unproductive guesswork for code that LLMs aren't familiar with by exposing API shapes from the caches of Metals and the Scala compiler.

Two great talks on building languages at #LambdaDays 2025: Nicolas Rinaudo will show you how to create a programming language from scratch and level up your tools and #DSL. 💻 Zainab Ali will treat docs like code, improving your workflow. #Racket #Elixir #Scala 📝 🎟️ Register here: www.lambdadays.org

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.

I had a fantastic time at the conference—connecting with Scala enthusiasts, enjoying great talks, and sharing ideas. Special thanks to the @Softwaremill for an amazing event! I was honored to speak this year, and I’m sharing my slides here: majk-p.github.io/functor-on-a... #Scalar2025 #Scala

Thank you, @scalar-conf.com! I had a blast! Here are the slides for my talk "Retrying the retry design": michalplachta.com/slides/retries You can find the code (PoC!) at Github: github.com/polyvariant/... ("o rety!" is Polish for "yikes!" 💥) Blog post and hopefully some PRs coming next week 🤞

That was a good one!

Welcome to the 11th edition of #scalarconf

Interested in learning more about Rust 🦀 or Scala? This week, @rustikon.dev and @scalar-conf.com Conferences are happening in Warsaw — both organised by us at @softwaremill.com . It’s a great opportunity to connect, share knowledge, and dive deeper into these technologies. 1/2

I shared a controversial take the other day at an event and I decided to write it down in a longer format: I’m afraid AI won't give us a "compressed 21st century" Here: thomwolf.io/blog/scienti... It's an extension of this interview discussion from the AI summit: youtu.be/AxBd3G0lFLs?...

Every tech company* has platform teams trying to build: 1. Heroku, except hand-rolled 2. One giant shared database, so engineers can ignore analytics without consequence 3. If they have a monolith, microservices. If microservices, a monolith 4. A solution to the halting problem * Hyperbole. I hope

It was great to see everyone at yesterday's #Kraków #Scala User Group meetup! A big thank you VirtusLab for hosting us 🙏 If you couldn't make it, I'll be giving the same talk online at the Functional World meetup www.meetup.com/pl-PL/functi... Save the date 📅 See you there!

Turned out if you only have Bluetooth keyboard and mouse with your desktop PC, it's a mistake to accidentally turn off bluetooth in settings.

did the folks behind tree-sitter ever get some sort of award? with hindsight, it was industry-changing stuff — completely transformed the landscape of syntax highlighting.

Much of the essence of building a program is in fact the debugging of the specification. -- Fred Brooks

#Scala community page just got an update with a list of meetups🎙️ Check it out if you are want to meet fellow enthusiasts www.scala-lang.org/community/#m...

#Scala tooling spree is happening next week!

I've been thinking about the Local-first Software ideals and translating them into concrete qualities. Here's something I'm musing on: 10 yes/no questions to determine how "local-first" something is. Open to feedback! What are your 10?

This has been a long time coming! Have you ever wondered what lenses and UI programming have in common? Can we recreate React, Elm, and Redux entirely using pure category theory? Read this series to find out. cybercat.institute/2025/01/21/u...

- I wonder why these functionalities takes them so long, it's just a few simple changes - a few simple changes: github.com/scalalandio/...

Metals 1.5.0 has been released! 🦦 - inlay hints for worksheets - error reports improvements - stability fixes Try it out in your favourite editor! scalameta.org/metals/blog/...

I tried the snapshot for the entire day and it looks awesome! That might be placebo but I didn't have to clean/import and the overall IDE experience was much smoother. Definitely give it a go if you haven't already!
