Experimenting a bit more with HotChocolate this morning to see what GraphQL is like in .NET these days. Good to see they adopted source generators. It makes the configuration much easier. I also found the new approach to data loaders and resolvers much nicer!

Fiddling with opencode this weekend as well. It's on par with claude code if you ask me. And it supports open source models. Aaannddd.... it supports remote access with security, so I can let multiple people work from one machine.

So, I spent some time today trying out the BMAD method. I only got through the research phase. It is insanely big. If you're an experienced developer I wouldn't recommend it.

Can I just say that I absolutely LOVE the frontend-designer plugin for Claude Code!

My oldest son wanted to learn how to design objects for the 3D printer. We made parameterized lego brick in fusion 360. Tomorrow we'll do it all over again in tinker cad. Way easier to learn :P

Time to start another print! More gridfinity bins to store random small objects. I find myself printing a lot more stuff now that the printer is so easy to control.

Improving my personal website. I'm going to bury some old posts, because nobody wants to read those anymore. And I think new stuff should get a good place.

After experimenting some more, I've found the pipeline to generate jurassic park-like pictures with open-source image generation models in ComfyUI. The workflow is not really straightforward to be honest.

Time to call it for today. I'll leave this here.

Things are getting better! Generating images with SDXL models applying style transfer with a reference image :D

Having some well earned fun generating images for my blog. But locally! Now to figure out how to include a control net for even more control over what the app generates.

Time to break the machine. Generating dinosaur images with a completely open-source workflow!

🚀 Week 1 van mijn 365 Days of AI Code challenge! Het thema: tooling voor tooling. Van daily summary scripts tot security audits - een meta-laag op het experiment zelf. 2.599 prompts, 46 commits. Lees meer: https://joopsnijder.nl/blog/week-1-2026

I couldn't resist....

Calm down prisma! I'm only resetting my development database. Who has access to production from his personal workstation without extra precautions anyway?!

Can somebody make a proper summary of the press conference done by president voldemort? It's very hard to get through all the crap that comes out of his mouth. 95% is not relevant to what he's done. Good grief.

Setting up nx in my monorepo to help claude code to better understand the project structure. Also curious about what this is going to do for my build process.

Cleaned the macbook (the physical outside), checked in the last code for 2025. Time to light the BBQ and have a great new years eve with the family!

Hacking away at a sidequest with the awesome tunes from Marsh: www.youtube.com/watch?v=4UE7...

I set a challenge for myself today. I'm going to vibe code a website to share prompts, skills, and agents, with agents, skills, and prompts. Essentially, I'm upgrading my context engineering prompt set to use agents and skills instead of just plain prompts. Should be fun!

Teaching my oldest son how to make pizza. We made the poolish. Tomorrow we're making the dough. And only then we can make a pizza. His patience is tested to the limit, but he likes the whole process. On to a killer pizza!

My test review agent is getting there! I can run self verification. I do need a few test issues 😆

I just donated to the Python Software Foundation! you should do it too! donate.python.org Because I love this language, and I hope more people will use it :-)

Creating more claude code subagents to delegate my work to. Just created a nice agent to manage the backlog items for me. Now I only need to write down ideas, and it will pour them into the format I need so I can add the necessary details more easily.

Or you could run a full data platform on your machine.... #daysbeforexmas

The final days before christmas and everybody on teams I work with are gone for the holidays. Never had this much time to focus on building some custom agents in claude code. It's amazing!

Turns out COSMIC desktop released last week and it's quite stable for a 1.0.0 release. At least so far :P

Experimenting with Cosmic desktop in a VM. While qemu is really flexible, it also is a bit of a pain in the behind to configure. You have to specify everything on the commandline. Every time! But there's a trick: echo "$(fc -ln -1)" >> script to save the command :D

Mission for today: Build a small army of review agents for specific topics to perform a full code review on a code base. This is going to be so much fun!

Digging through my outlook to find out which assignments I worked on this year. It's surprising how many customers I spoke to and how many projects I had meetings with.

Having fun with hugging face and nvidia parakeet. Going to write a blogpost about this later.

Changing my coding agent so it run the unsloth version of Qwen3-coder. It has some essential fixes for tool calling. Hopefully it makes things even better :D

If you're frequently designing systems, it's nice to have a graph like this to help you identity quality goals and scenarios to solve for those goals: quality.arc42.org/full-quality... The Q42 quality model is just awesome :D

Okay, so you can build agents with all sorts of nice frameworks. But now, the agent is running on the server, and your tools are on your local machine. So far, I have found plenty of agent SDKs that don't support this particular scenario. Bummer!

Printing the first piece of a christmas tree. Because we can.

Completing the first fully functional version of helix, my personal coding agent. It uses local LLMs like Qwen 3 coder to allow you to write code without having to use OpenAI or other LLM providers.

Allright... One more!

Yeah, that sounds about almost right. Except for the lack of wheelchair. Looking forward to finishing all the scenes and dino combos!

Testing the next update for the trading card generator. The sports cards are still super awesome!

Wondering if I could run Flux on my own machine instead of going through a major cloud vendor. Just because I have more control and don't have to deal with broken portals....

Can I just say that Microsoft Foundry, Azure AI Foundry, and Azure OpenAI confuse the crap out of me? I had a working deployment for gpt-image-1 before, now it's broken, and the user interface sucks really hard.

Okay, I feel silly: Been looking at an ignored package-lock.json wondering why Github Actions was so freaking broken it wasn't seeing my lock file. Turns out: you should check it in.... Here's to 41 years being me 🎉

Just upgraded the libraries for the trading card generator in preparation for bitbash! If you want a dino card, come join us during the event: www.bitbash.nl

Figuring out how to use a Git library to get changes from a local repository so I can build a review agent. For fun and giggles of course.

Running Spotify Backstage with Aspire 13 is a breeze. Especially now that you can use file-based C# applications to run the application host for Aspire.

Turns out that printing a file on linux is a lot simpler than it is on windows: Use the lp command with the file name. Optionally, you can configure two-sided printing with a command-line option and setup collation in case you need to print multiple copies with more than one page.

Module 5 of 6 for the bitbash workshop is done :D Final module coming right up!

Finishing the coding agent labs. The agent can now write its own labs?!

@defaultconstructor.com the poop shoot for the printer is done! I choose a model where the bucket is on the side of the 3D printer. Works well :D

Today, I'm pre-celebrating my birthday and post-celebrating my wife's birthday. Why? Next year I'll be 42, and that's the perfect age. The answer to everything. This year is just weird. Although 41 is a prime number, I'm looking forward to next year for the number alone.
