on my way to @socrates-conference.at - although it is only the second time for me, I feel like this is a key event for me already

Cool to see that @openfeature.dev and flagd can be used in Quarkus. Feels good seeing the projects you are contributing to, to be used.

#LeftOfTheLoop is progressing

Simon Schrottner @aepfli.bsky.social · 06/08/2026
The agent runs the fastest #loop anyone has ever had: output, correction, output again, until the code matches the spec. What it can't correct is the spec. Questioning the frame instead of the output is a different loop, an older and slower one, and it still needs the room. #LeftOfTheLoop #AI

You can't prompt for what you don't know to name. #LeftOfTheLoop

The agent will hold any direction. It can't tell you yours is wrong. #AI #LeftOfTheLoop

The loop amplifies whatever understanding the team brings to it. If the team didn't build shared understanding before the loop ran, the loop executes the misalignment faster. #AI #LeftOfTheLoop

We were still in the room together. We had stopped thinking together. #AI #LeftOfTheLoop

#AI agreement is cheap. Human agreement from the right person is not.

Simon Schrottner @aepfli.bsky.social · 15/07/2026
Teams have always known that upfront alignment produces better estimates, and that's not a new idea. What's new is that #AI makes the alternative, skipping the alignment, running the agent, seeing what happens, feel so productive in the moment that the incentive to do the upfront work disappears.

My blog post series/braindump "Left of the loop" is growing fast. I have too many ideas floating around, how I think a team could heavily utilize loop engineering, without losing its shared understanding. schrottner.at/series/left-...

An agent helps you ship the wrong thing faster. The ever-agreeing genie grants the wish exactly as you worded it, never the one you meant. The team was the part that pushed back. schrottner.at/2026/06/26/T... #ai #softwareengineering

The Ever-Agreeing Genie
Anthropic’s engineers ship eight times more code than they did a few years ago. And they had to start scheduling lunches so people would talk to each other. Fiona Fung, who leads the Claude Code team,...

hot take: most companies are just giving devs AI tools and calling it innovation 🙃 wrote about what I think actually needs to change — spoiler: it's not the tooling, it's the process and yes, I am leaning on XP terminology. no regrets ;) schrottner.at/2026/06/18/T... #softwaredevelopment #ai

The Wrong End of the Problem
Every company wants AI in their development process right now. That part is clear. What’s less clear is where they’re putting it.

We've been putting ourselves in the middle of the software delivery lifecycle. By design. 🤔 What if the job is writing fitness functions instead? 🤔 Not reviewing pull requests, but defining what survival looks like.

The worst part of being laid off so far, was the uncertainty, what's next, when, how, etc. Somehow this is a new level of discomfort for me. Externally induced, but I already feel like I am learning something. And to be honest - the community (everywhere), is amazingly supportive. Thank you all!

What started as “let’s add some OpenTelemetry to a Python game” for my talk… …turned into a microservice refactor, clear service boundaries, and CI/CD everywhere. AI-assisted dev speed was wild. Dashboards, traces & metrics weren’t just visibility - they fueled the refactoring. Massive learnings 🤯

So the night train adventure starts... Sidenote: that's what you get for traveling by night train to most conferences -> kids who also want to ride the night train. To be honest I am really looking forward to this adventure with the kids.

Some tools force you to learn a complicated API and require constant maintenance. Other tools... just work, and that's why it's easy to overlook them. @openfeature.dev is one of those tools. Do I use it daily? Yes. Do I ever have to think about it? No.

My Zurich adventure feels more like being a hostage of @swisscom.bsky.social - wanted to get a prepaid, system does not work, trying to cancel with the shop's phone, 40min on the line already. Cannot leave because roaming would be too expensive. At least they try!
