KaiserPister··on Extrinsic World Modeling with Opus, Astra and Grok
This is a small study on the capabilities of different frontier models on manipulating Blender + 3D objects.
KaiserPister··on Formalizing Fermat's Last Theorem
13M LoC, are we sure it didn't exploit any latent issues in the lean proof system?
KaiserPister··on Show HN: TapToyPia
This was a lot of fun! I beat it in just under 30 minutes but lost to the new settlers.

Thanks for sharing!

KaiserPister··on Show HN: We analyzed 1,573 Claude Code sessions to see how AI agents work
This is awesome! I’m working on the Open Prompt Initiative as a way for open source to share prompting knowledge.

That’s probably fair which is why I tried to be upfront that this is shilling. I figure some people might be like me, interested in sprites but not artsy enough to make them. You might start with an ai sprite and fix it via LibreSprite or another tool.

Thanks for your opinion

Like the comment above I split sprite sheets into grids with edges for NBP to follow. I have the option to add the canny edge map to the grid to enforce a lot of consistency as well. Then I specifically tailor the prompt to the task.

But even still it has issues sometimes.

Exactly! On my tool I specifically use 4x4 grids which is limiting and I use canny edge maps to help enforce consistency. A very fun problem to solve!

This is 100% true for artists. But I am not an artist, and I like pixel art stylistically. So when I make sites or games, I need to either: use my bad art, hire someone on fiverr, or use AI.

I'll shill this project again: I built myself a small sprite generator because I'm a terrible artist.

If you're looking for pixel-art sprites, check out 8bitsmith.com. Or you can just ask Nano-Banana for sprite sheets and it does a pretty good job!

KaiserPister··on Nvidia PersonaPlex 7B on Apple Silicon: Full-Duplex Speech-to-Speech in Swift
That’s a bit reductive. Some do, others don’t. I do a lot of AI development, and building. But I value the act of writing for clarifying my thoughts. And I value other people’s time when reading my writing.

I do agree it is one of those “if I had more time, I would write a shorter letter” situations.

But in this case the piece is wordier than a bad human writer would be. If they want to use ai for writing, so be it, but at least include “concisely” in the prompt.

I am strongly put off by the LLM writing in this piece. It makes me question quality of the project before even attempting a download.

Who would put effort into building this only to compose a low effort puff piece?

KaiserPister··on SpacetimeDB ThreeJS Support
We have been experimenting with adding Spacetime multi-player to our current threejs app. It was surprisingly easy to build the standalone demo but the full integration obviously is not as straightforward.
KaiserPister··on Sprites on the Web
I built 8bitsmith.com as a tool to make controlled sprite sheets. It was an experiment in vibe-coding and controlled asset creation, so pricing is basically a pass-through cost of using Gemini.
KaiserPister··on Ask HN: What are you working on? (February 2026)
I built teach.af as a flipped classroom environment where students will “teach” AI bots to enhance their understanding of functional programming.
KaiserPister··on Ask HN: What are you working on? (January 2026)
I needed some pixel art for a different project, so I made 8BitSmith, a simple pixel art & sprite generator.

I'm expecting it is pretty niche, but animations tend to be very time consuming for people like me, and getting quick sprites that I can drop into a platform is a big time saver.

The project was 90% vibe-coded and I documented the tech stack here: https://www.8bitsmith.com/tech-stack
