At Dartmouth College, computer science started as a branch of the Mathematics Dept. It was eventually made it's own department (located in a former clinic for the mentally ill, Sudikoff Laboratory which some see as ironic). Now Dartm

There are Xylitol sprays also, advertised for moisturizing a dry mouth. Spray, swish, and spit it out and little will reach your intestinal microbiome. Best done right before a time when you won't be eating or drinking so the residue

My dentist said that chefs have a lot of problems with tooth decay since they do so much taste testing, so she recommends they keep a glass of water with some baking soda mixed in handy to rinse with after tasting.

Don't these head down designs for motorcycles kill peoples necks? Having to keep your head tilted up means the bike is only useful for short drives. Ride it across several USA states and your neck will be frozen, especially with the

So were the epidemiologists wrong about herd immunity and the USA has hit herd immunity at 50% vaccinated (plus natural infections, some of whom also got vaccinated)? I do not think we know what is going on right now, it is very strange th

I see this news as a loss of faith in the police. If the police are not trusted or not helping or making things worse then of course people will form their own gangs for protection. Citizen is trying to profit off that. Businesses and rich

I remember getting trapped by bullies inside a cone made of concrete at an industrial site along the railroad tracks 50 years ago. They were threatening to kill me and given the remoteness of the site and the fact that these kids often kil

I think this is what confuses many people when they do their own tests, they don't know what to listen for and expect a more general sound quality difference over all parts of the recordings. The differences are actually in particular

This has happened more than once, maybe it is by design? :-) How would a machine learning algorithm get trained to see police vehicles as invisible? Maybe learning to ignore sunlight flashes makes it ignore flashing lights in general?

Here is an odd theory: metamaterials DO exist naturally in the universe (but are not prevalent on Earth) and are the explanation for dark matter. In other words our sensor data is warped.

Don't clean the house very often, let the yard go wild, hire others, build on existing systems instead of from scratch.

Note that the attackers can also threaten to release data. Backups are no protection against that. They could also corrupt data and not tell you which part was corrupted and when, so even if you have backups you don't know which ones

There is not a huge range of choices. I considered TI's chips and worked with a student who had some measure of success using BT on a dev board. I would recommend looking over the support forums for any candidate chips, you will quic

This is already happening. For example people steal medical records and use the data to get medical care for themselves and others, pretending to be the identity they have stolen. So false data gets into the medical record and can not by

This is a specific version of a more general problem, namely that scientists only study what interests them, therefore there are gaps in what gets studied. There are fads in scientific research, just like everything else people do. Not su

This is very similar to radar, which raises the question, is radar already used to spy on peoples movements through walls?

Depends on the chip manufacturer. Nordic obsoletes versions of their Bluetooth chips at the drop of a hat. I worked for 2 years on a smartwatch that used the nRF51822 and they went through about 8 revisions of the chip during that time, oc

How did criminals pull off international blackmail, kidnapping, and extortion before cryptocurrencies? Did it always require a local bagman? Could ransomware criminals not resort to the same tactics?

Use radar for targeting. WiFi has been used to see peoples bodies through walls, 10GHz has been used in radars, the same beam that destroys can be used to image the target. You may not even need to do imaging, just look for resonance or i

Perhaps because those involved in computer security don't see any end in sight. It's widely acknowledged that there is no such thing as perfect computer security, if someone wants to get in bad enough they will. Zero-days will al

Why in general has RAM been so limited in computers for such a long time? A decade ago we were expecting new kinds of RAM to replace hard disks entirely, using new computer architectures that did not use disk drives at all. Instead most g

How about thinking through how bias in algorithms should be tested, discovered, and fixed and building that in? Some types of testing might be statistical for example, and involve trying software on a large group of people with a variety o

So it this the UWB version of AirTag? The one that can locate a tag to within an inch and give precise direction and distance to the tag?

My suspicion is that WUSB died because it used UWB which was/is very difficult to hack. The signal looks like random noise distributed across a wide spectrum and if you don't know the secret key it's hard to tell if there is
