Newton Raphson could be used to calculate a reciprocal. (in a bit width larger than 8). If starting from a good reciprocal approximation, convergence to bit accurate reciprocal should not take many iterations. Then multiply the reciprocal with the numerator to perform the divide
I worked on an automotive FMCW LiDAR that didn't quite make it to market. Cool technology but it was difficult to scale the cost down, which is pretty important for automotive. Margins are very low in that market
It's also, if not more so, a factor of transistor voltage. 1.1V transistors are less prone to upset events than 0.7V. It's possible (assumption, here) that some 3+ volt circuits are still used for critical components of the system
It would be possible to use much higher supply voltages if silicon were replaced with a semiconductor material having a higher band gap.
The main obstacle that has prevented this until now is that in all high-bandgap semiconductors it is easy to make only transistors of a single polarity, not transistors with both polarities, as required for CMOS logic. For high circuit densities it would be difficult to replace the CMOS logic, because all alternatives have higher idle power consumption.
I'm curious too. I'm guessing it's something to do with sonames & rpaths which often need fixing up during installation (CMake does this for example). I haven't ever used Bazel for distributing Linux binaries so maybe it just doesn't have that built in.
(I would go with statically linked binaries anyway tbh.)
It's a perfect time for Matt Colville's MCDM RPG to be announced. It's on backerkit and people are clearly eager for something different. The crowdfunding is at 4x funding and climbing
For what it's worth, I had absolutely nothing to do with the post: I didn't make it or encourage anyone to make it. I just noticed a sharp uptick in sales earlier today. Which I love since I spent a lot of time and money designing the poster and getting it printed. Here's the real buy bait: Please buy my book and poster! You can find the book "Tools" on Amazon, and the poster at theodoregray.com
Also for what it's worth, it's a very cool art project! And I'm always happy to have more computer nerds get an introduction to the tools required to make stuff in the physical world.
One that changes color the longer you brush so that you know you've brushed sufficiently (and not just blood-red to indicate your gums are now bleeding).
One that changes color based on where the calculus on your teeth accumulated, so you can target you brushing.
One that does the brushing for you, just keep it in your mouth for 3 minutes and rinse.

This exists, although for some reason I'm not aware that it's available as part of a toothpaste. (Maybe the toothpaste foam would create false positive indications by making it seem to accumulate in places that don't actually have plaque.)
Blast! I was hoping readers would be too young to remember and I would get the credit. \O_O/ ... I used to get these from the dentist as kid in the 70's.
