Thanks. It would be great to get some more detail on this. Quick note, it seemed like it supports only closed-world ontologies.

Cool! I tried to find some information on what versioning is like. I'm not very familiar with OWL and RDF, but I'm trying to get a sense whether the diff between two ontologies is like the set difference between the set of RDF tri

At some point, any GA computation bottoms out to scalars. Since you start out with quantities you already know how to give dimensions to, I would expect you can just follow standard dimensionsal analysis. That isn't to say it's st

I agree with the first sentence. But I don't think it's intuitive to learn about complex numbers through GA. Complex numbers are a great jumping-off point to learn GA since it is simple and most people eventually accept that the i

I think there is a two-part answer to your question. 1. What's the difference between Geometric Algebra and exterior algebras? Clifford algebras? This is a hand-wavy explanation, but the GA community has specific GAs give a geometric m

Your comment encouraged me to read it, so thanks for that. I thought a bit about the phrase "planned for future versions" and I felt like I could see where there was a sort of miscommunication. If someone said: "Future versio

A shock absorber contains an element that does damping and a spring. The ideal capacitor can only be one of those elements in the analogy, I think.

You're right. From https://en.m.wikipedia.org/wiki/Decoupling_capacitor Since capacitors differ in their high-frequency characteristics (and capacitors with good high-frequency properties are often types with smal

If you learn about https://en.m.wikipedia.org/wiki/Decoupling_capacitor you'll see that there is more to the consideration than "just use the highest capacitance capacitor".

I don't think it's useful to think of capacitors as bad batteries. The only point I was trying to make is that a component doesn't have an inherent "ground", so you can reference one pin to any voltage in the circui

The way I see it, this isn't really about capacitors. You could do the same thing, not practically but conceptually, with a rechargeable battery.

Why did you read that it's not the case? I read the opposite. That if the LED broke, you'd notice it because your camera would be on and the light would be off. Not that the camera never turns on.

That doesn't necessarily mean that you need to check in auto-formatted changes. You can just autoformat the two revisions before feeding it to the diff program. Of course, a lot of tooling simply isn't there for that, unfortunatel

Suppose you do foo a lot. And sometimes you need to do either foo or bar inside of baz. You can pass a flag to baz, to choose either foo or bar. Now you have a closed set of possibilities. If you want to extend the functionality e.g with a

Testing is important, for sure, but just because you have two parameters with n choices each, does not mean you have to test n^2 combinations. You can aim to express parameterization at a higher level than ifdefs. For example, template para
