Regarding yesterday's meetup, an interesting project was presented: dapr4s. 💡 It combines the Safe #Scala initiative and DAPR's durable runtime abstraction. This concept offers the cleanest and most reliable approach to building distributed systems I've ever seen. It moves all infrastructure implementation details away (retries, observability, database), leaving just the pure business logic tracked by capabilities. It's hard to explain everything in a single post since the presentation lasted nearly two hours (and had 89 slides! 😀), so check out the repository examples if you're curious 👇

I've been maintaining fs2-rabbit for a couple of years. I thought the project was dead, but then I saw new likes on the recent releases. ❤️ If you use a library, please drop a reaction on a new release from time to time. It's a huge motivation boost for maintainers! ⭐

While waiting for truly safe, capability-based agents that operate through the Scala compiler, sandboxes keep things reasonably secure. Here is a brief comparison of Docker Sandboxes vs. VirtusLab Sandcat:

Since sandboxing agents is recent hobby of mine, I’ve been looking at the new Docker Sandboxes (sbx), and how they compare to Sandcat.

If you're in Prague 🇨🇿, come join us today at the Fun JVM meetup! The main topic is Safe Scala and Distributed Application Runtime (DAPR) - which lets programmers focus entirely on writing business logic. ⚡️ Plus: a lightning talk about Snapshots4s!

Another series from a former #Scala developer who switched to #Rust. I wonder how many of them will eventually come back - and not just from Rust. I'd love to see those articles too, because it's definitely happening.

The latest patch update, Scala 3.8.4, is out now! 🎉 This release features scala-cli upgrades alongside multiple security fixes for the compiler and standard library following a recent audit. Also, one chapter is closing - the Ammonite REPL is now deprecated and scheduled for removal. With #Scala 3.9 right around the corner, is this the last version before the LTS?

If your Postgres query joins 9 or more tables, you should really ask yourself if it is time to rethink your architecture 😀 But also check the join_collapse_limit parameter, since Postgres defaults to an exhaustive search of just 8 tables ☝️

💡 Quick tip: Use `sbtn --no-server` if you want full control over your running sbt instances. It stops the native thin client from automatically spawning a background server process if one isn't already active. #scala

Dependabot is finally getting support for sbt! 🎉 It is currently in beta, making it a decent option for polyglot companies wanting to keep all their security alerts in one native dashboard. That said, #Scala Steward remains the best option for dedicated Scala ecosystems. Check out the progress here:
