People often forget that architecture in (central and northern) Europe is build under the assumption that the climate has more cold extremes than hot extremes. Thus, buildings were constructed to both retain and collect as much heat as poss

Audio glitches like the one at 45:15 ( https://youtu.be/4S8I22ybG2c?t=2715 ) make me think even the interview video might be generated.

I am curious what kind of plasma is used, as there are many ways to create plasma under various conditions, with very different efficiencies, selectivity, yield, etc. Among the worst is the Birkeland-Eyde process, hot plasma by electric arc

> It avoids the issue of a winding number by assuming there's only 1 bezier curve per triangle The original paper did assume no overlap yes. But that is not how anybody would implement it. For a long time one would use the stencil b

I think it is limited to integral quadratic bezier curves, which is sufficient for text rendering. But general purpose vector graphics almost certainly want rational cubic bezier curves too.

There are two ways to get winding numbers and then decide on filled or empty by some rule like non-zero or even-odd: a) The winding number of a point is the number of intersections of a scanline and a closed path. b) The winding number arou

Really depends: In some areas it is quite advanced (rendering) and in others it is lacking / underdeveloped (editors / tooling). But there is an incredible amount of progress and also churn in keeping up with that. https:/&#

Another point in case: Life only exists in liquids, not in solids (too much structure) and not in gases (too much chaos). In fact one could argue that this is a definition of an interesting system: It has to strike a balance between being c

Not yet, I agree, but who is to say they couldn't? Limiting life to cell based biology is a somewhat lousy definition by the only example we know. I prefer the generalized definition in "What is Life?" by Erwin Schrödinger wh

The normal key layout with its irregular (within an octave) gaps allow one to play blind without having press and hear where you are with your fingers. Would be interesting to add braille or similar haptic markers on the keys to compensate
