Akka.NET

🔭 @AkkaDotNET Community Standup tomorrow (Wed May 13 12pm Chicago Time) "End-to-end distributed tracing for Akka.Streams" 1.5.66 ships an `"Akka.Streams"` ActivitySource that propagates trace context through your stream graphs; we cover that and more.

Sorry folks - had to cancel our "End to End @AkkaDotNET " training today due to persistent audio issues with GoToWebinar. We've booked a make-up date for this Thursday at 11am Chicago Time. petabridge.com/training/

Actor + AgentLoop = a composable agent The Actor model (Hewitt, 1973) gives you encapsulated state, single-threaded message processing, and supervised lifecycles. An agent loop needs all three — a scratchpad that won't tear under concurrency, one tool call at a time, and a parent who can cancel or reset it. AgentZero Lite wires Akka.NET actors directly to LLamaSharp / OpenAI-compatible loops to get those properties without re-inventing them. more : #agent-models" target="_blank" rel="nofollow noopener">psmon.github.io/AgentZeroLite/…

Had to revert one of our changes in @AkkaDotNET v1.5.66, the Task.Yield change to Akka.Persistence that moved serialization onto a background thread. It had great performance numbers but it compromised the way some of our persistence plugins worked internally and correctness always beats performance. This has been addressed in v1.5.67

Used Netclaw to fix a DNS resolution bug inside @AkkaDotNET 's networking stack using Qwen3.6 Not bad for a local model (and a harness I rolled from scratch) github.com/akkadotnet/akk…

Adding OTEL Tracing to @AkkaDotNET streams so you can visualize graph + workflow shape. Tested against a lot of different graph combinations and it works great so far.

New Blog Post / Video: "Managing Long-Running Tasks Inside @AkkaDotNET Actors" When we're syncing a new @TextForgeApp user with 15+ years of inbox history with over 100k emails, this is how we do that reliably + efficiently using actors. Read: petabridge.com/blog/akkadotne…

New @AkkaDotNET Release - v1.5.65 - Fixed 3 Akka.Cluster.Sharding bugs that could cause problems during rolling restarts (usually with leases enabled) - Fixed xUnit3 implicit `TestActor` issues in the TestKit - Fixed a decade old configuration bug in core Akka

After 11 years, we decided it was time for a fresh look for the Petabridge website. Now with dark mode for Akka .NET Bootcamp and all of our blog posts too.

Our new @AkkaDotNET training calendar for Spring 2026 is live! See the 📅in next post

Important Akka .NET release today, v1.5.63 - Adds Xunit3 support to our testkits - IMPORTANT: fixed an old Akka.Remote bug that is probably responsible for the vast majority of quarantines. This is an important stability fix!

Probably the most entertaining show and tell we've done for an Akka .NET Community Standup: "Grimmloch - Building an AI-Powered MMO with @AkkaDotNET " youtube.com/live/2Z4piVx8N…

Welp, @AkkaDotNET Cluster.Sharding passivization was responsible for a very weird bug in @TextForgeApp I'd been scratching my head over. Been wondering why my account showed as "not synced" for two days and why I wouldn't get Slack notifications sometimes. Turns out, syncing a big inbox takes longer than the default 2 minute automatic passivization timeout - and the actor that runs that job could never quite finish on-time.

Don't miss our community standup on Wednesday - "Grimmloch - Building an AI-Powered MMO with @AkkaDotNET " Learn how tools like Akka Persistence, Cluster.Sharding, and more all play a pivotal role in making games re-entrant, horizontally scalable, and fun! 🔗in next post

Phobos 2.11 is now live on @getsdkbin - big feature in this release is we've finally deprecated "append logs to trace" because log / trace correlation now works naturally via Akka .NET Hosting 1.5.60 and later. No more "double logs" and other annoyances

Working on getting Akka .Hosting and Akka .Management releases out the door shortly

Akka .NET v1.5.61 is now live on NuGet. Lots of fixes in this release: - [IMPORTANT] multiple edge-case Cluster.Sharding bugs - Fixed 2 Akka.Cluster edge-case bugs - and more See the full release notes here: github.com/akkadotnet/akk…

Tomorrow at 12pm CST - our February Akka .NET Community standup. Featuring: - Logging scopes + context enrichment - OTEL logging integration - Aspire support for Akka .Cluster - Source Generated Serialization preview for v1.6 🔗 in next post

Ryan Xu made a pluggable ETL pipeline engine on top of @AkkaDotNET and OSS'd it 👀
