Prompt-to-install: yes or no? (of course, especially since this is for a project which sets up sandboxing, such prompts should always be run in ask-permission-for-everything mode)

Based on your feedback (thanks!) we've updated our Agent Visualization! What's new: * better mobile view * clearer labels - what's generated by the LLM vs. tool output * improved prompt, so that it's easier to follow the reasoning What do you think? virtuslab.com/agent-visual...

adopt-tapir.softwaremill.com now uses the latest&greatest #Scala 3.8.1 Generate a one-file scala-cli project exposing a self-documenting HTTP API, or a full-fledged multi-module-ready sbt project with tests. All type-safe & LLM-friendly.

An update of Sandcat: a dev container setup for securely running AI agents in `--dangerous` mode * no forwarding of SSH/GPG agents into the container * restricted VS Code settings to lockdown the environment

Are you into #Rust? Or hoping to get into the ecosystem? Then @rustikon.dev is for you :) A friendly community, meeting for the 2nd edition of the conference. And we've got a great agenda!

Continuing the quest to lock down #AI agents in a sandbox: here's Sandcat, a dev container setup that intercepts all container network traffic, filters it & injects secrets. Your API key values never even exist in the container. But you retain the convenience of reviewing & browsing code in an IDE

Learn Kafka essentials from a Confluent Elite Partner 💪 There’s plenty of theory out there, but nothing beats production experience. We’ve seen exactly what works and what breaks in high-scale data streaming environments. Download the ebook: softwaremill.com/ebooks/start...

The best way to start a Monday morning might be to get some @scalar-conf.com tickets - just over a month away! Make new friends, meet old friends, find out how #Scala might fit into the #AI ecosystem with trustworthy agents - an opening talk by Martin Odersky, and much more!

Once again, I'm happy to report that @softwaremill.com received the #GreatPlaceToWork Poland award. Congratulations - and thank you - to the team :)

While reading the "Build a LLM from scratch" book, I get to appreciate how intricate and complex the architecture of an LLM is. The common narrative is that It’s "just" throwing a lot of compute power at a deep neural network - but as often in life, there's a lot more nuance.

Financial platforms rarely fail because of missing features. They fail because their systems cannot scale, evolve, or react fast enough to reality. See how Apache Kafka solves 7 real problems of financial institutions: softwaremill.com/business-ins... #ApacheKafka #dataengineering #FinTech #Finance

We're gathering feedback on our AI Agent visualization: virtuslab.com/agent-visual... Does the site help to understand how an agent works? What can we do better? Which parts could be explained with higher clarity? Thanks for the help! :)

First post on benchmarking @tigerbeetle.com and #PostgreSQL, covering test design and local, single-node results: softwaremill.com/tigerbeetle-...

Latest sttp-ai contains a type-safe library-based agent loop implementation. Provide the tools (automatically derived from #Scala functions), and you're good to go! Works with OpenAI, compatible APIs, Claude, and all Scala effect systems. Next up: MCP integration.

The full agenda is now on our website 🔥 👉 Visit www.rustikon.dev/agenda for all the details! Don't have your ticket yet? Grab it here: www.rustikon.dev/tickets We can't wait to see you in Warsaw this March! #rustikon #rustlang #rustprogramming #learnrust

Thanks to Robert Pudlik, sttp-ai now has an agentic loop implementation: provide the tools (which might be as simple as a #Scala function), and let the agent do the job! Integrates with #OpenAI (& compatible LLMs), as well as Claude. More details here: github.com/softwaremill...

We don’t just use Scala at SoftwareMill. We help shape the ecosystem. 1⃣ Scalar since 2014. 2⃣ Scala Times every week. 3⃣ OSS contributions. 4⃣ Talks. Articles. Real‑world engineering. 🔗 Get in touch to talk your Scala project: softwaremill.com/contact/ #Scala #SoftwareEngineering #Scalar

Kotlin 2.3.0 just dropped! 💎 From nested type aliases to smarter exhaustiveness checks for when expressions, the latest version is a major win for code readability. Find out more: softwaremill.com/kotlin-2-3-0... #Coding #Kotlin #DevCommunity

How does an AI agent work? We've prepared a visualization to help you understand just that: how an LLM is involved, where tool invocation happens, and how an agent loops. Enjoy! virtuslab.com/agent-visual...

We've got a long & rich history with #Kafka, and this is a culmination of our efforts led by Michał Matłoka - congrats! :) Multiple client deployments, certifications achieved, OSS projects, educational materials - there are many ways in which we are involved in the Kafka ecosystem.

Why is it that it’s the exciting part of programming that is automated (coding), but we’re expected to do the boring one (code review), not the other way round?

Happy to report that jox helped uncover a bug in the #JVM (race in virtual thread scheduling). My first after 20 years of working with #Java :) bugs.openjdk.org/browse/JDK-8...

You’ve probably heard of TigerBeetle. But do you know what actually makes it stand out? 🤔 🔗 @warski.org explains why it is so interesting: softwaremill.com/whats-intere... #Database #FinTech #Clustering #Replication

Adopt-Tapir gets even simpler! You can choose an SBT project (multi-file + tests), or a single-file scala-cli script. All you need to get started with a self-documenting, type-safe, observable JSON API is generating a single file with ~30 lines of code. adopt-tapir.softwaremill.com

Jox's Flows (#Java virtual-thread native asynchronous streaming) now have a #Kafka integration, thanks to Robert Pudlik: jox.softwaremill.com/latest/kafka...

You might have heard about @tigerbeetle.com - but do you know why it's interesting? Fixed schema - sounds limiting. Replication, high-availability? Everybody says so (well, at least a lot do). Still, TigerBeetle is different. Here's why: softwaremill.com/whats-intere...

What happens when you vibe-code a simple web app and check against the OWASP Top10 vulnerabilities? Well, you get a lot of ❌. True, the use-case has a lot of opportunities to make mistakes, but then, which use-case doesn't? softwaremill.com/vibe-coding-...

✨ Concurrency doesn’t have to mean tangled abstractions. This session walks through Ox 1.0 and its direct-style approach to concurrency and resiliency. Here’s "A Tour of Ox 1.0: Direct-Style Concurrency and Resiliency" by Adam Warski

Interesting take on separating Tapir endpoint descriptions & the server logic, while making sure that every endpoint is used & implemented: github.com/arkida39/baku

Robert Pudlik is always the first to try out new coding models, IDEs and tools (and with a new IDE each day ... that's a lot of work). And with good effects! But his AI usage is guided by rules - he describes how to effectively do so below: virtuslab.com/blog/ai/how-...

YavaConf was a blast🔥 Thank you to everyone who attended the presentations by Adam Warski, Michał Zyga, and Artur Skowroński! The 2026 lineup promises to be equally rich and engaging, and includes @rustikon.dev and @scalar-conf.com! We hope to see you there, too! #yavaconf #jvm #java #loom

It's not everyday that your work colleague writes a book for Manning! Especially that Manning has a strong brand, which just makes this even more interesting!

Due to a surprisingly fast code rot, the runnable examples in the Chimp library (type-safe, boilerplate-less #MCP servers in #Scala using the HTTP transport) didn't work OOTB.

In case you would run out of YouTube content to watch, two of my talks are now publicly available: "What is Functional Programming?" from @lambdadays.bsky.social www.youtube.com/watch?v=pnZS...

Latest Tapir (#Scala rapid self-documenting HTTP API development) offers more precise logging & metrics. So that you always know what's up with your application! github.com/softwaremill...

While I was reading I kept thinking, isn’t this like Rust’s borrow checker and indeed: “Given the foundation provided by the capture checker, the Scala team is now working on using it to implement separation checking. This will allow tracking the use of mutable values and the aliasing of references”

Safe resource usage is coming to #Scala! Scala 3.8 is just around the corner (you can test 3.8.0-RC3) - it's a great occasion to try out capture checking. But first, you have to understand how it works - here's my attempt: softwaremill.com/understandin...

What did we #AI this month? Łukasz Lenart explains how to configure Claude, with an example involving JetBrains's MCP. Jacek Centkowski describes how he prepared a lightning talk with #ChatGPT.
