In this video, Alex shows an awesome demo of using DBOS's fork to debug agents (yes, we can fork out your bugs 🍴). Check it out!

Agentic loops can take on a long running, non deterministic path. If there's an error late in the execution, reproducing it is hard because a second execution may never follow the same trajectory. In this demo, we inject an artificial prompt error into our @hackernews Agent demo…

The latest episode of the #BugBash podcast has Qian Li from @DBOS_Inc talking about the hard truths of ergonomics. As always, if it ain't easy, it probably won't happen. Full episode links below.

Gunnar is such an incredible writer! He explains durable execution better than I do. I love seeing more lightweight, database-backed approaches getting attention, and really appreciate the thoughtful shout-out for @DBOS_Inc . Always grateful for folks who push the space forward.

While "𝚞𝚜𝚎 𝚠𝚘𝚛𝚔𝚏𝚕𝚘𝚠" is incredibly simple syntax, I need to give credit where it's due - @DBOS_Inc discovered the simplicity long ago. Check them out if you want a similar workflow framework that doesn't 𝚞𝚜𝚎 𝚍𝚒𝚛𝚎𝚌𝚝𝚒𝚟𝚎𝚜 and is not limited to just JS

Huge congrats to the Yutori team on the release! 🎉 Check out their powerful new web agent. It's seriously impressive and backed by solid research. So proud to support you all from the DBOS side.

Thanks QCon for having @qianl_cs and @jedberg. Their talk covered how durable computing and DBOS Transact boost reliability, remove heavyweight workflow coordinators, and reduce both complexity and cost.

We're back on HN! This time with our Postgres-backed durable execution library for Java. It plugs into existing Spring apps with minimal changes and gives you durable workflows, queues, retries, and scheduling without extra infrastructure. Feedback very welcome!

This is such a lifesaver. I was running a few demos recently, and the biggest pain was juggling multiple providers. I spent an hour setting up API keys for OpenAI, Anthropic, Google Vertex, etc., then hopping between dashboards just to track cost. PAIG makes model access so much…

Just built a cool demo–a deep research agent that gets Hacker News’s take on any topic. Because it’s built with durable workflows, you can watch it run in real time and see what it’s reading and where it gets ideas--really helpful for debugging/reproducing issues.

The recording was just posted for my talk at @redpandadata Streamfest! Check it out–cool overview of how durable workflows help you build reliable AI apps and how you can integrate both agents and workflows with streams. 👇

Our inaugural PyAI event is a wrap! Was incredible to bring together nearly 100 builders across the Bay to discuss what works, what doesn’t and what’s next. See you for our next event in New York next Friday November 21st during AI Eng Code.
