Delivering quality web solutions is out of my realm of expertise, so if I were to hand it off the experience would probably would probably be lack-luster.

ClosedBridge is my small consulting company in the embedded space, and I'm just spitballing ideas to bring eyes to it.

If you manage to move the cart to the rail limits it'll typically fall over and enter the swing up state.

With that said it's a pretty simple design, made more for the novelty of an interactive logo.

I really liked OpenSCAD as a concept, but when I started designing things that had a fair bit of complexity the rendering engine really shit the bed. This was a powerful rig as well.

There are search spaces that are quite large that are used in optimal control. GPUs can be used to drastically accelerate finding a solution.

As an example, imagine you are given a height map, a 2D discrete search space overlayed in the height map, 4 legs, and robot dynamics for every configuration of the legs in their constrained workspace. Find the optimal toe placement of the 4 legs. Although a GPU isn't designed exactly to deal with this sort of problem, if it's framed as a reduction problem it still significantly out performs a multi core CPU.

Any chance there is a correlation between Obelisks and autoimmune diseases?

I actually worked for a startup that makes tiny FPAA's (Field Programmable Analog Arrays) for the low powered battery market. Their major appeal was that you could reprogram the chip to synthesize a real analog network to offload the signal processing portion of your product for a tiny fraction of the power cost.

The key thing is that analog components are influenced much more by environmental fluctuations (think temperature, pressure, and manufacturing), which impacts the "compute" of an analog network. Their novelty was that the chip can be "trimmed" to offset these impacts using floating gate MOSFETs, the same that are used in flash memory, as an analog offset. It works surprisingly well, and I suspect if they can capture the low power market we'll see a revitalization of analog compute in the embedded space. It would be really exciting to see this enter the high bandwidth control system world!

I confused Sourcetrail and SourceGraph, didn't mean to spread misinformation on your product!

Yes you're right, my mistake!

Ideally this would be a standalone app (perhaps ported using electron) that I could run locally, and import codebases directly. Sourcegraph was on the right track, but eventually fizzled out unfortunately.

I would love to use a tool like this to navigate the unknown on rails!

I'm glad someone stood up to Jobs, what a complete and utter asshole. Nothing says job security like telling your boss that their demands are "bullshit"
