Here's my temporal-clone attaching the VS code debugger to a workflow that ran in AWS. If something breaks in prod, I can just grab the executionId and use the debugger to step through exactly what happened.
Here it is, a simple clone of temporal (as a library) that can run on AWS serverless or any other cloud provider. Is this something people actually want though? github.com/sam-goodwin/mini-…

THAT'S IT? This is what 20 years worth of spent nuclear fuel looks like safely stored at the former Maine Yankee nuclear plant. `The energy produced from this fuel helped avoid 70 million metric tons of CO2 emissions.

I'm curious when being a “full stack” developer starts to include things like setting up basic RAG pipelines? I used to think GenAI would be its own discipline but as I get deeper into the space it feels like it's going to be a must have skill along with basic DevOps.

5yo: “Dad, I have something to tell you. It’s just for you. Not mommy.” Me: *mentally preparing* “OK buddy I’m listening” 5yo: “well… when the narwhal blows the invisible bubbles..” Me: “omg go to sleep”

Some org cultures are PM Dominated: In such a culture, PMs call all the shots, are seen as the sole source of what needs to be built & why, other functions such as Eng & Design mostly work in service of the PMs & “The Business”. While some PMs want to work in such orgs, you should understand that they almost never build very good products. Largely because these other functions are not allowed nor incentivized to care deeply about the user experience and the end business outcomes. They are repeatedly asked to “stay in your lane” when they bring up questions, concerns, ideas about why we are building what we are building. No matter how great a given PM is, that greatness cannot overcome the resulting apathy of the other functions who are directly designing, building, and marketing the product. That’s why a PM Guided culture is much better for ambitious PMs than a PM Dominated culture. Here’s what you can do as a leader to move your team / org from PM Dominated to PM Guided: youtu.be/3Nvd9W4mgvQ

I'm happy to announce I'm suing every customer who offboards from my product. It'll be integrated into the exit interview process so customers get a seamless suing experience. Don't @ me or I'll sue.

I wonder if anyone has looked into analyzing how content propagated across websites to detect fake, and increasingly generated, content.

I suppose my hypothesis is that real news and genuine content propagates across some channels slower than fake content that is immediately syndicated without the burden of verification.

Nice - Not sure if everyone is aware that you can can use Workflow Studio locally within VS Code.
Using #StepFunctions Workflow Studio via #AppComposer in @code. I might be late to the party, but I'm glad to see that it now supports definition substitutions. Really good experience 🙌 Reminds me of a happy era when #AWS pushed DX tooling unpolluted by GenAI.
