One potential application might be fighting wildfires. Seems like it would be really useful if one firefighter could remotely monitor a dozen autonomous bulldozers that were given general instructions. Would have to acquire a different tr

About 20 years ago the CS community was getting excited about optical memory. It promised to be huge, must faster than static RAM, and hold it's state. Tied directly to the CPU as a very large cache+RAM replacement it would have revo

I worked with an SGI 2400T workstation and it came with a 4:3 aspect high resolution monitor (4K I think, different from today's 4K). Later workstations probably had wider screens. However even that old machine could display to a wid

That's actually the ROM Kernel Reference Manual (RKRM), not the Hardware Reference Manual. The RKRM was another great reference manual for the Amiga. Quoting from the preface: The Amiga operating system is composed of libraries, devi

Could this produce a 3D model of a plastic case that will perfectly fit a PCB board? Could it be improved to also produce the CAD files for a PCB board?

Everyone in the US is not going to buy a new car and a new home heating system within the next five years, but longer term that may be true. EV's can be charged off-peak to level the load without requiring new grid infrastructure. So

Could the oil companies be funding the AI companies in an attempt to keep fossil fuel demand high and make renewables seem like they are not reducing oil demand? This could be cost effective for the oil companies since they don't ha

Wild land does regenerate, but also trees grow, and they have a cost to remove them when they get bigger, especially the roots. Plowing is not possible with tree roots everywhere, though perhaps non-monoculture non-mass-produced crops are

The CIA triad comes from an agency that spies on people so I wonder if it truly is a comprehensive philosophy of security. It might be an attempt to confuse those they spy on with the intent to encourage security gaps. Philosophies of any

I believe switching sides in war, such as abandoning the interests of our NATO allies and those we have sworn to defend, is usually called Treason and those who do it are called Traitors.

I've often wondered if lead in products is part of an intentional attack on the Western world. Maybe it's just a side effect of lowering production costs, but it could also be an attack to make a nation sick and stupid. The lack

Why hasn't anyone launched deep space probes intentionally to get the kind of data the Voyager probes are sending? Seems like a purpose designed probe could last even longer.

Dexterity is also hard because, at least in humans, it relies on knowing something of the nature of an object _before_ manipulating it. Is it light or heavy? Soft or rigid? Is it a bag of popcorn, popcorn kernels, a bag of powder, or a p

The MSP430 can be put into an extremely low power sleep mode (microAmps I believe, though you have to turn off all it's peripherals also) which means the MCU will not draw down the battery over time, leaving it fully charged and ready
