halcwb.bsky.social @halcwb.bsky.social · 16/09/2026Using Claude in plan mode explicitly telling only to report and not to change the code base. Guess what? Immediately goes off and starts messing up my code base. AI is going to kill humanity, purely by frustrating us to death. 000
halcwb.bsky.social @halcwb.bsky.social · 15/09/2026I now believe AI will destroy humanity. By driving them crazy trying to get them to do what you want them to do. If that's there secret mission, AGI is here. 000
halcwb.bsky.social @halcwb.bsky.social · 12/09/2026My #fsharp #GenPRES project is going very well, thanks in part to AI. But I work with one important base rule: if at any moment I need to proceed without AI, I must be able to do so. If not, my code base is in trouble. 041
halcwb.bsky.social @halcwb.bsky.social · 18/08/2026I don't think most is anti-LLM per se, but more how LLMs are framed, used and hyped. Personally, I think LLMs are fascinating and groundbreaking, but also still very much an ongoing topic of research how to use them properly. 100

halcwb.bsky.social @halcwb.bsky.social · 09/06/2026Completely agree. Not to say that AI is useless. Extremely handy when learning, exploring, explaining. But engineering or creating something, really really bad and dangerous. So, we have a tool but don't know how to use it properly. 110
halcwb.bsky.social @halcwb.bsky.social · 09/06/2026Ok, I am now definitely have learned my lesson now, having a LLM write code is a really, really bad idee. Explaining code, explore, etc.. fine. But actually writing, bad idee. In the end I am losing more time trying the LLM what I want then just write the code myself. 000

halcwb.bsky.social @halcwb.bsky.social · 17/05/2026With Claude improved my Monadic skills: To get a new monad you change exactly three things — the type M<'T>, return', and bind — and return' is usually trivial, so the real design work is the one lawful bind.

halcwb.bsky.social @halcwb.bsky.social · 17/05/2026AI is great, for knowledge, not understanding. I use it to: 1. Improve my understanding and skills 2. To test and challenge my coding 3. Write code (or have the AI do it) Using Claude the quantity doesn't go up, but the quality does. And, by the way, #fsharp and AI are a great match! 271

halcwb.bsky.social @halcwb.bsky.social · 07/05/2026This is what is happening right now. Claude uses the fsi-mcp to slowly and step by step implement a plan in #fsharp. AI + #sharp + #fsi-mcp 232
halcwb.bsky.social @halcwb.bsky.social · 05/05/2026Also, the problem as described in this video is far less using #fsharp. Note that you really need to pay attention to your domain model, but once that has been fleshed out, AI can pretty much infer the rest. youtu.be/cPoEFM1AKE4?...youtu.beClaude Code Is Resurrecting Our Worst NightmaresYouTube video by Zoran on C# 072
halcwb.bsky.social @halcwb.bsky.social · 05/05/2026Well, I can testify that it all works as the article sums up and even beyond. I use the fsi-mcp were the AI gets direct feedback. And that works wonders. It even is pretty good at writing fsharp. But might be, I was quite bad to begin with 🤨 The thing is, it's #fsharp so when it compiles it runs. 130

halcwb.bsky.social @halcwb.bsky.social · 25/04/2026If there are serious issues with Ionide then I probably can fund solving those issues. We are going to invest in #fsharp as the main language to create meaningful clinical decision support software. Finally, this is long over due! 061
halcwb.bsky.social @halcwb.bsky.social · 23/04/2026I know that the Ionide team as an open source project always struggled to keep up. Actually, just lately Ionide became much more stable than previously. So, to me it sounds a bit like the chicken and the egg. If we don't support them how do we expect them to keep up? 100

halcwb.bsky.social @halcwb.bsky.social · 12/03/2026So true, it all boils down to: "AI's primary role in software development is to amplify. AI magnifies the strengths of high-performing organizations -- and the dysfunctions of struggling ones. 010
halcwb.bsky.social @halcwb.bsky.social · 12/03/2026This blog sums up the reason why I choose for #fsharp to program a complicated clinical decision support system #GenPRES: cekrem.github.io/posts/why-i-...cekrem.github.ioWhy I Hope I Get to Write a Lot of F# in 2026The FP language that does what Elm does, but on the backend, with full .NET support 050
halcwb.bsky.social @halcwb.bsky.social · 11/03/2026And I would love getting people on board using #fsharp to write great clinical decision software like #GenPRES. Great blog and I couldn't agree more with you. For complex domains (like medicine), #fsharp just shines! 110
halcwb.bsky.social @halcwb.bsky.social · 07/03/2026This is what a lot of code will look like in a couple of years. 000
halcwb.bsky.social @halcwb.bsky.social · 07/03/2026And again blindly relying on Claude can get you in serious trouble. This was plan wrong!! 000
halcwb.bsky.social @halcwb.bsky.social · 07/03/2026Amplifying learning, I am all with you. For that purpose AI can be very effective. But again quite dangerous as well. Beware of the brain rot😜. There is also literature how AI can diminish critical thinking and intellectual skills. 110
halcwb.bsky.social @halcwb.bsky.social · 06/03/2026That is so true. And something that also impacts usability of AI. I haven't seen cases where the AI said, I have added this feature and also abstracted some previous code away. The opposite seems to happen. 020
halcwb.bsky.social @halcwb.bsky.social · 04/03/2026That is a very valid concern! That's why I created a workflow that prevents repo-assist to directly meddle with my source code. Instead I have it make coding suggestions implemented in isolated scripts. But besides that, with respect to issues handling, documentation etc.. repo-assist is a great! 100
halcwb.bsky.social @halcwb.bsky.social · 04/03/2026I think this is one of the most valuable #fsharp libraries. Would it help to see if the repo-assist from @dsyme.bsky.social could help? With some explicit rail-guards it is very useful for my project: github.com/informedica/.... Preventing direct edits of my source code.github.com 120
halcwb.bsky.social @halcwb.bsky.social · 01/03/2026Hard problems require hard work. No LLM is going to fix that. I have burnt myself a couple of times to learn that lesson. 000
halcwb.bsky.social @halcwb.bsky.social · 28/02/2026I am getting very enthusiastic👏 about this. Repo-assist has now labeled all my issues as a first step. 010
halcwb.bsky.social @halcwb.bsky.social · 27/02/2026Now, extrapolate that to all the claims that AI is going to take over software development and all sorts of other intellectual jobs. ??? 000
halcwb.bsky.social @halcwb.bsky.social · 27/02/2026So, just adding a column to a markdown table turns out to be a massive challenge not only for Claude Opus 4.6 but also GPT-5.2 is really struggling. Note that it perfectly "knows" what to do, only the actual adding of the column to a otherwise simple table seems a real problem. 100
halcwb.bsky.social @halcwb.bsky.social · 26/02/2026Everybody is talking about how AI is going to take over programmer jobs. I just asked Claude Opus 4.6 to align markdown tables in a document. A very simple and humble question. It proceeded with some python script that really messed up things. I think I will continue writing my own code.😅 100
halcwb.bsky.social @halcwb.bsky.social · 26/02/2026The reason: "If you were primarily working with C#: Use our newly introduced file-based apps!" This doesn't bode well for any other language than C#. 010
halcwb.bsky.social @halcwb.bsky.social · 26/02/2026I can understand that, but doing coding myself (at least for me) is essential in getting to the right solution direction. Mozart could compose a piece right from his head, I am no Mozart ;-). As for real guards, a strongly typed domain is the best you can get and that is a strong point of fsharp. 100
halcwb.bsky.social @halcwb.bsky.social · 26/02/2026I have the luxury to be able to choose my language. And I hope that I can afford more F# developers in the near future! Depends on my institution whether they will get the financing. 010
halcwb.bsky.social @halcwb.bsky.social · 26/02/2026It could also be the next million dollar mistake. I have had mixed results with AI coding. It's fine with established practices, but if you want to create something new, that's a whole other thing. 100
