True story. Guess how I know. 😅
Thanks. I quickly read the key points and need more time for the rest.
I mainly use line completions from GitHub Copilot and they are fine.
We did some trials with generating bigger pieces of code but it didn‘t work well - not because of F# but a lack of understanding by the LLMs of our domain.
That‘s my preferred kind of a spec, but it‘s the same for any kind of spec.
"We don't need software engineers anymore; AI agents can generate the code from specifications. We only need people who can write a precise specification that can be understood by an agent."
What you need is a software engineer, then.

A typical Monday, which is also the first day of the month, is ending for our application for time-tracking and the like.
The first two days of every month see higher loads because people close their previous month's accounts.
Thanks to Azure, everything scales automatically with load.

Sketchnote from Wednesday's .NET user group Zentralschweiz meet-up with Glenn F. Henriksen (@henriksen.no) about practical advice to build glorious monoliths:

Great, now I have an additional problem: where to find sand.

My recording "studio" is my kitchen. No regrets — it's the coziest room in the house.
Setting things up to film #csharp coding tutorials for the #pxlclock. Write code, run it on the simulator, watch it glow on the real thing.
First tutorials dropping soon. Stay tuned!

#fsharp is awesome , try it out and learn somewhat an #ocaml / ML language too in the process #dotnet . Think outside of the box 📦 > use your own intelligence , Human Intelligence 😇🦔💚🥳🙌 (AI can help). try also Fharp data nuget with json or csv for example and play with .fsx and REPL . Have fun 🤩
Almost ready to ship: deploy C# apps directly to your PXL Clock. Write code, hit deploy, it compiles on the device. Looks familiar? :)

Given how much we've been sharing our work with the #fsharp community, we thought it worth summarizing this pivotal decision to establish a new language. speakez.tech/blog/reintro...
If you are ever in Switzerland and near beautiful Lucerne, we (a .Net user group - not focused on .Net only) would be honoured to host a session with you.
We pay for additional travel and hotel costs, of course. 🙂
This week on Friday @dsyme.bsky.social shows us how agentic workflows can continuously improve #fsharp libraries.

"Instead of writing code, we can finally concentrate on what's important: architecture and business problems."
Ivory-tower architects are back then?

"Specification is the means of communication with stakeholders."
What happened to face-to-face communication (manifesto for agile software development)

I follow what is happening in the AI/LLM/agents space as closely as I can. Lately, it sometimes feels like backstepping into the last millennium:
"We need a correct, complete specification so that agents can then implement it."
Replace agents with developers, and it sounds like pre-2000.

I do not fear the rise of superintelligence.
I do, however, fear the rise of billionaires, organizations, and world powers who seek to use computing to maximize their power, influence, and control.
Recent situation.

What is 1+1? Would an AI be broken if it gave an answer other than 2?
If you expect "2" you don't really understand how LLMs work. For at least two reasons.
