It would be neat if you could print in some of the jellybean components - even just covering a range of resistors would be interesting.

Pcb manufacture has long used screen printing techniques to apply solder paste and label stencils. The new part here is using it to apply things like conductive ink traces. I would think there are different electrical characteristics to acc

There's a large set of different algorithms with a sliding window. Another interesting one is the Rabin fingerprint. This kind of chunking is often used in storage file systems w/ deduplication and snapshot features. https:/

NVMe is built on PCIe, so latency wise, they will be limited by the PCIe latency (roughly an order of magnitude slower than the memory bus though pcie 5 may be smaller than that) + media latency. Throughput wise, they are limited by the nu

The generation of flash chip in the drive can make a major difference there, as well as fill, the wear of the drive and it’s internal firmware architecture. The makers also target different tiers of performance with different model lines to

From what I’ve seen a relatively simple radar is what many automakers are using as the main sensor for AEB. You can see them on the front grille, usually a small rectangular patch in the plastic about the size of paperback book. Though thos

In addition to the other good comments regarding medical/automotive overlap, is that often those chip lines have long lifecycle commitments built into them - ie. we promise to make this set of parts for at least 10 years. For both both

Someone with the right background and contacts should put it together, I think the smart move there is to not only plan on selling chips into regular markets, but to get into talks with customers to become a guaranteed supplier that derisks

Wait for a teardown and select a place to drill your own hole? But yes, a surprising lack of design forethought.

Logistics analysis probably has a lot of crossover w/ queuing theory. How big a buffer should one maintain if you want the user to be able to keep consuming a video stream for an up to x second packet loss window vs how big an inventor

I wonder if there are intermediary steps to getting to better at causality in ML. Causality is an abstraction of a whole set of a lot of different levels of problems. In terms of concrete problems earlier than causality. E.g. toddlers I thi

Wouldn't one of the "obscurity" features in this case be how few messages were encrypted with the cipher? If there were a larger database of encrypted messages, it may have been more susceptible.
