I was contacted for a potential internship based on my post in "Who wants to be Hired?" in Feb 2020. I have prior background in industrial control systems, and the startup which interviewed me had some overlap as they focus on pow

The concept of this looks pretty powerful - the timelapse video on Youtube did a good job of showing me what I wanted to see. Devil's always in the details, of course, but at the very least, it seems like this could speed up the creati

-140C only works for CO2-rich streams (> 10%). As the partial pressure of CO2 decreases, you'll need to get asymptotically closer to the melting point of oxygen/nitrogen. You'll also need to increase the pressure, but agai

> How much energy will you need? A lot. Air compression is not cheap, energetically. Chilling is also energetically expensive. You'll need to do both. This would be pretty much the "brute force" method, like O(n!) in softw

I'd figure that for human eyes, it would make the most sense to generate pallets from colors that are equal distance in the CIELAB colorspace[0] (or similar). I personally love the Dracula Pro examples on your webpage, and will definit

I'm glad you did! Additionally, is there any reason that I should learn React using Node.js rather than python? I'm not particularly anti-Node.js but I'd rather learn Django simultaneously if it was all the same difference.

I will try to link to this explanation for situations I come across in the future. It's very well argued. For what it's worth to future readers, I went ahead and found examples of optical fiber rated for use up to 385C[0] (20km).

I mean, it's napkin math right? The idea is to see if it's worth doing actual calculations. Even oil companies can't drill deeper than 10km in most areas because the heat destroys any material drill, even the most durable cer

I think that silicon and data compression are well-optimized domains already. However, Neural Nets are provably horrible w.r.t resource efficiency, as demonstrated by recent advances like EfficientNet, which managed to decrease the number o

Light in fiber optics travels 31% slower than the speed of light in a vacuum, and does not travel the ideal "great circle" route.

Light travels 31% slower in fiber optic cables than it does in a vacuum. (Speed of light is only constant in a vacuum, not in arbitrary media). It can be faster to send the signal into space and bounce it off a satellite, than it would be t

The ones I'm thinking of were "nomograms" (thanks to user 'chemeng'). Visually they look like perhaps a very specific subset of "Parallel coordinate" graphs. Definitely more for calculation rather than vis

I enjoyed using OneNote and Microsoft Teams on projects which had some remote workers and satellite offices. I think the biggest thing is that everyone has to buy into the communication modes which work for remote work. If 80-90% of the tea
