its a graphdb like neo4j and cozo and direct-to-file (instead of client-server with network delay inbetween) like sqlite and cozo.

Also, I could be wrong but this project sounds like it has an index optimized for bi-temporal data, useful for audit purposes, eg "what was the exact state of the db on september 12th". in neo4j you would have to add that information as indexed properties on each node and edge in addition to other indexes. not sure about the actual performance differences here but I guess one could structure the data more efficient in the first case for time sensitive data usecases.

looks like an attempt to create efficient agent memory.

The arm (or whip) would still have to accelerate from 0 to ~2000+ rpm on half a revolution even though its flexible. So there would still be enormous accelerations even though the whip eventually partly smoothens out the peak acceleration. it would be more like a collision which in turns introduces higher stresses (and probably vibrations too) to the system. Both requiring you to increase the strength + rigidity of the system and hence also increase weight on the arm. Which in turns increases inertia and the "collision" effect.

Not saying its impossible to create a successful system like that, in fact it sounds sort of a natural/organic design that potential could be closer to the optimal design, but it would be more difficult to accomplish and probably need more testing and design iterations. So I think OPs strategy is more simple and pragmatic in this case.

that predictive key feature is hilarious. At 4.20 in the video.

How on earth can that be faster than typing on a regular qwerty keyboard.

I'm all for alleviating psychiatric/mental health disorders, but yes, some topics are worth skipping research on. For example chemical/biological/nuclear weapons, human cloning, and unethical gene modification.

I just like to challenge myself, as an engineer, with the idea that not everything has to be engineered and optimized. What if we simply left some things unexplored and mysterious, and trusted nature and our own human capabilities?

A better way of alleviating psychiatric/mental health disorders might just be to focus on societal factors.

For what purpose? To replace humans? To make social media more addictive? To master brain manipulation?

> oomwoo is organized so the community can build it in parallel. The robot and its software are split into self-contained modules. You pick whatever module interests you, work on it whenever you want, and submit your work as a pull request. Multiple people can tackle the same module — the best solution surfaces over time.

I think one major advantage of open source over commercial alternatives, is the possibility of endless improvements. Similarly, 3d printing as a manufacturing method allows for a short iterative cycle, high degree of design freedom, customisation as a product feature, local production, and an high degree of repairability.

It’s going to be interesting to see how well git(hub) and discord serves as collaborative tools in this case. Hardware files are often binary, hardware components have complex interfaces between them, and hence depends more on human communication and collaboration.

I really hope this project succeeds. I’d love a cloud free robot vacuum that I can trust.

I’m excited about the genAI future. I’m a software engineer interested in product, user experience, architecture, and entrepreneurship. After 4 years in the industry, mostly within fintech, I have gotten tired of slow organizations, company politics, nontechnical managers doing the decisions etc.

I’ve saved up a couple of months of salary, have a couple of bootstrap ideas that I believe are within reach for me equipped with a coding agent to build. Hosting can be done almost for free. What used to take entire teams and hence millions of dollars to build can now be done a lot cheaper. If I’m lucky one of those ideas can pay my bills soon. If not I’ll go back to consulting for a couple of months.

Does anyone know what file format they are storing the color information in?

Seems like the volumetric extension of 3mf files could support it. That would make cross slicer file mgmt easier.

Clajjan is this you?

I’m building a web app that optimizes fdm 3d printing print profiles based on geometry, material, hardware etc.

Hopefully this can help people reduce filament usage and waste, speed up print times, and improve print quality.

It’s beautiful to see. They have put in such extreme amounts of hard work to get that thing into the air. Designing a robust affordable liquid propelled rocket from scratch is hard. There are so many design decisions, complex simulations, manufacturing difficulties, and tests for every little part of that 11+ m rocket. Accounting for extreme forces, heat variations, vibrations, wind, atmosphere, liquid sloshing, rotation, etc during ascent and descent. It’s not only mechanical/aviation engineering but also software, electrical, sourcing donations, documenting everything in forms of design and risk assessment reports etc etc.

You also have to try to account for every little possible failure mode before launching which is why rockets seldom succeed on the first attempt.

And then dealing with authorities to create new launch sites and permits which probably hasn’t been done in decades in Canada.
