Great article by @askowronski.bsky.social on the different levels of context that you can provide to an AI agent. Which levels do you have at #$WORK? virtuslab.com/blog/ai/the-...

Can you cut your cloud bill by 50% without sacrificing performance? One of our clients, a global leader in cybersecurity, did exactly that by migrating their massive EDR system from GCP to Oracle Cloud Infrastructure (OCI). See how we helped them with this high-stakes migration:

Through a series of experiments, we've prepared a direct-style #Scala Skill for Claude Code. We wanted to make sure that it only contains what's really necessary, and to help Claude where it stumbles. Even with a 1M window, context remains precious!

ElasticMQ - an in-memory @awscloud.bsky.social #SQS implementation for testing - just got a new UI! Thanks to Michał Ossowski for his continued stewardship of the project and new development :)

Our client engagements often start with workshops on architecting the optimal setup for #Kafka clusters. @mmatloka.bsky.social wrote down some of the basics of the process - still a long read, but who said disaster recovery is easy? softwaremill.com/guide-to-apa...

Problems with error handling and exceptions, part N+1; is that a sensible way to categorise and implement error handling? * recoverable, "expected" errors. Fully typed, as an `Either[E, T]` or `Result<T, E>` or a checked exception

Proteus - Tapir-style #gRPC endpoints in #Scala, by Pierre Ricadat, just got #Ox integration for streaming responses! All in direct-style, leveraging #JVM's virtual threads. Check it out :) github.com/ghostdogpr/p...

Just got my copy of DDIA by @martin.kleppmann.com, 2nd edition - one of the best books if your interests lie anywhere near distributed systems. Proud to see @softwaremill.com among the acknowledgments! Even if our contribution was only financial, it's great to be able to support such works.

Best way to get a feature implemented or bug fixed? Talk to us @scalar-conf.com ;). Plus, our contributors are as active as ever!

We're closing the #Scala survey 2026 tomorrow, 26th March 2026, 23:59 CET. If you haven't yet, now's the time to take part :) virtuslab.typeform.com/ScalaSurvey2...

Another approach to consumer-agents-at-scale. Instead of sandboxing, verify that the agent stays within limits. LLM generates code on the fly, a compiler verifies it. That's the approach described in the recent "Tracking Capabilities for Safer Agents" paper by Martin Odersky et al

We're steadily getting waves of registration on Shelly - our educational programming language for drawing. (I can only guess that each "wave" is a student group doing assignments.)

Sandcat got @1password.bsky.social integration: the config can now contain `op://` references instead of secret values, which are then resolved through a service account at run-time. github.com/VirtusLab/sa...

I'm definitely having a déjà vu ... where did I see this kind of slide before? ;)

What kind of guidance does an LLM need to write a direct-style #Scala 3 application? At the baseline - not a lot, e.g. Claude is quite good both in Scala 3 & direct-style. For finer details - some additions to the prompt might be useful. Read more: virtuslab.com/blog/scala/g...

A lot of updates in Sandcat - our Docker & dev container setup for securely running AI agents in `--dangerous` mode: github.com/VirtusLab/sa...

Only one day left until Rustikon... Are you ready? 🦀 Last call to register and join the partner event: Rust on Blockchain organized by Superteam Poland 👉 luma.com/RUST-on-chai... Rustikon starts tomorrow! Registration begins at 8 am - see you there!

If you're using macOS and Homebrew, we have some great news for you! Thanks to the great work by Piotr Chabelski, installing Scala via Homebrew now includes native-image binaries. This means the CLI starts faster and doesn’t require Java to be installed on your machine.

Last call to take part in the #Scala Survey 2026! We're closing it next week, just in time for @scalar-conf.com How are you using Scala, and where should it head next? Let us know: virtuslab.typeform.com/ScalaSurvey2...

Latest Jox (Virtual-thread based safe concurrency & streaming for #Java) brings in a number of new operators on `Flow` (the streaming component): batch, conflate, extrapolate, recover, mapWithResource and more More: github.com/softwaremill...

I had been coding from 1995 until 2025 - not every day, but more days than not. Good times! From 2026, I've been generating code instead, with just a handful of LOC written manually. Is this the new normal? Just an intermediate step? A witness of the kind of code I write?

Last call! @rustikon.dev or @scalar-conf.com or both? :) Is AI-generated safe #Rust code going to take over the world? Or maybe #Scala is the language for AI, with its token efficiency and static verification of generated code? Join us this & next week :) www.scalar-conf.com www.rustikon.dev

Only a week to @rustikon.dev! Two days covering everything #Rust - just take a look at the agenda. In the center of #Warsaw. Don't miss it! :) We'll be there with our team. www.rustikon.dev

Low productivity gains with LLM-coding are probably because everyone is trying to come up with an optimal agent workflow, instead of shipping features. But when we have that workflow ready ... prepare for an autonomous agent-delivered productivity and business value tsunami ;)

If you're not yet fully immersed in agent-assisted programming, we've got some resources to get you up to speed! First off, agent visualization: interact with a real LLM and see how and when are tools called virtuslab.com/agent-visual...

Are we going to rewrite everything in #Rust? Is Rust the best language to generate code using AI? These would be my bets for the hallway track of @rustikon.dev - 19-20 March in #Warsaw, Poland. If you don't have your ticket yet - don't wait any longer :)

Only a month left until @scalarconf! The agenda's there, the afterparty is planned - now you just need to get a ticket :) Affordable as always, in the center of #Warsaw, easily reachable by plane, train, bus, car (by bike and on foot as well ;) ). www.scalar-conf.com #Scala

#Scala's capture checking is useful not only when dealing with resources, but also when paired with other values that shouldn't leak syntactical scopes, such as Ox's concurrency scopes. Here's a short breakdown of how this works: youtube.com/shorts/ozoeD...

Latest Tapir (rapid development of self-documenting APIs) brings performance improvements when validating decoded request (e.g. JSON) bodies. Try it out! github.com/softwaremill...

On the left: Kruskal's minimum spanning tree algorithm as presented in CLR's "Introduction to Algorithms". On the right: an implementation of the same algorithm, here in C++. Quite terse, but still much richer in technical detail, and the core idea is not that visible.

jox channels 1.1.2 (#Java virtual-thread based safe concurrency & streaming) introduce non-blocking trySend() and tryReceive() methods. Thanks to Andrzej Kobyliński for working on this! github.com/softwaremill...

We're running the 2026 #Scala Survey! Let us know how you are using Scala, #AI with Scala, and give hints to the Scala teams (both at VirtusLab and EPFL) on where the focus in driving Scala forward could be. Thank you - your answers count :) virtuslab.typeform.com/ScalaSurvey2...

After a couple of trial-and-errors, Sandcat finally works well for #Java & #Scala development, alongside IDEs such as Metals! The first sandboxed autonomously-created PRs are already merged into our OSS projects github.com/VirtusLab/sa...

FinBot: exposing data to a wider audience using natural language queries. Project profitability, employee metrics, quarterly comparisons - some examples of queries that our internal users asked. How does it work? Read the full overview by @kgrajek.bsky.social : softwaremill.com/reducing-tim...

A 01:46 introduction to what kind of problems capture checking in #Scala solves. Pushing forward what type systems might do! youtube.com/shorts/TJofT...

The second edition of Designing Data-Intensive Applications, by myself and @chris.blue, is finished and sent off to the printers! Ebooks should be available in the next week, and print books in 3–4 weeks. Sigh of relief. 😅 (BTW, this is a good opportunity to support your favourite local bookshop!)

sttp-ai now supports #Scala Native! You can use: OpenAI, Claude, Grok, Ollama, ... With different flavours of Scala: direct, functional, Future-based On various platforms: JVM & Native (not all combinations are supported, though) Enjoy :)

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! :)
