In the meantime, I'm working on the 4th module of the coding agent workshop I'll be teaching at bitbash.nl in January! Come learn how to build your own coding agent :D
Bitbash - Free two-day event covering the latest Microsoft technologies
Get ready for an exciting two-day event that will cover the latest Microsoft technologies and innovations.

Uh ooh, I published my very first rust crate. A small utility that's really only useful to me, but still ;-)

Interesting video on why you shouldn't try to convince people of an idea. And I should be honest, I try doing that at least once per week. But I try to do better! www.youtube.com/watch?v=fDIL...

Upgraded the coding agent workshop to .NET 10 and progressing through module 3/5 to show people how to build a coding agent with semantic kernel.

Using a sub-agent to write instructions for my upcoming workshop. This is my workflow: First, create code for the final state of the lab. Next, write outline + introduction to the lab instructions in a markdown file.

And this took only 20 minutes to reach. So much for that plan.

Having a go at spec-driven development with Agent OS v2. This thing is huge but looks really well made. I made a set of templates myself, but this one is way more extensive and documented. Very cool!

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Uh ooh. @defaultconstructor.com made me buy a new 3D printer. Although, ours was broken, and my wife was pondering whether we should replace it with a more modern printer. Ours was 10 years old by now.

Setting up ollama to switch the coding agent workshop to gpt-oss so when people can run an LLM on their laptop they can do the workshop fully in open source.

With the recent developments in our country where a politician is actively causing doubts a well working election process I ran another round of critical thinking exercises with one of my kids to show them how important it is to think for yourself.

Important paper on LoRA vs full fine-tuning for continual learning: arxiv.org/abs/2410.21228
Although LoRA restricts weight updates to a low-dimensional subspace, which should reduce forgetting and be better suited for continual learning, this paper shows it may not actually be the case.

LoRA vs Full Fine-tuning: An Illusion of Equivalence
Fine-tuning is a crucial paradigm for adapting pre-trained large language models to downstream tasks. Recently, methods like Low-Rank Adaptation (LoRA) have been shown to effectively fine-tune LLMs wi...

The new agent session panel on github is quite nice I must say. I've been watching policy academy and making code at the same time. Building out ideas like this is quite cool.

I'm at it again, breaking my linux installation with some tweaks to my hyprland configuration. Started completely from scratch, styling the whole thing step by step. It takes a while, but I think the results are better and I have a much better understanding of all the tools involved.

I sponsor open source developers from time to time with a donation. Jesse Duffield is one of them. He makes lazygit, a git client I use daily.
Go sponsor open source people! These developers deserve it. It's a thankless job at times. And this shows how much you love what they make.
