Electric motor scaling laws and inertia in robot actuators
This is the beginning of a series of posts about robot actuation. The intent here is not to prescribe some specific architecture or solution, but to talk about the fundamentals, with as little bias as I can manage. Hopefully you learn something. Here’s an ostensibly straightforward question for anyone who’s spent time thinking about robot […]
Slicing Bezier Surfaces
It is possible to split a bezier surface into two pieces. It helps us to slice a surface into several pieces without losing the original shape. In that way we are able to delete one piece of several slices of a whole surface. function splitBezier(t, p0, p1, p2, p3) { const p4 = lerp(t, p0, […]
Are LLMs not getting better?
I was reading the metr article on how llm code passes test much more often than it is of mergeable quality. They look at the performance of llms doing programming when the success criterion is “passes all tests” and compare it to when the success criterion is “would get approved by the maintainer”. Unsurprisingly, llm […]
Big Data on the Cheapest MacBook

Apple released the MacBook Neo today and there is no shortage of tech reviews explaining whether it’s the right device for you if you are a student, a photographer or a writer. […]
Home Assistant waters my plants
Some readers will know, but most will not, that I am a bit of a self-confessed foodie. I enjoy cooking, but especially so when others get enjoyment from it. Be it friends, family, or neighbours, and sometimes all three, I’m always up for putting something together. Food isn’t what this post is about, but it’s […]
I don’t use LLMs for programming
I originally posted this on Mastodon, but I thought I’d add it here too: “What I mean is that if you really want to understand something, the best way is to try and explain it to someone else. That forces you to sort it out in your own mind. And the more slow and dim-witted […]
Dolphin Progress Release 2603
Dolphin started out as a GameCube emulator in 2003. In 2008, experimental Wii support was added. And now in 2026, Dolphin enters the realm of arcade emulation with support for the Triforce, a joint Sega, Namco, and Nintendo arcade effort. Want to learn more about the Triforce? Check out our deep dive into the Triforce […]
Avoiding Trigonometry (2013)
Intro I think we should use less trigonometry in computer graphics. As my understanding of projections, reflections, and vector operations improved over time, I experienced a growing unease every time I saw trigonometry at the core of 3D algorithms inside rendering engines. These days I’m at a point where if I see some asin, acos, […]
3D-Knitting: The Ultimate Guide
Is 3D-Knitting Better For The Consumer? We mentioned that 3D-knitting creates stronger seamless clothing, but what makes this technology so exciting? Well, with this tool, we can explore endless design capabilities because various stitches can be placed within a single garment. For example, a jersey knit, rib knit, or jacquard knit can transition into a […]
