Maybe someone cares to speculate about replacing Bluetooth for AirPods. It fits easily in the bandwidth of UWB. AirPods are ideal candidates for better locating ability. I can’t say for certain but a rough googling suggests that the radio a

I used to drive for a much shorter commute. At the time I could have been urgently summoned to a site 30 miles away at any time so I had to be prepared. I ran out of gas on my way home one night. If you never drive past a gas station and on

Don’t let the “quora.com” make you skip this one. It’s a detailed and informative discussion of the U1 and UWB as understood today. I was pleasantly surprised.

Human perceived brightness is something like a logarithmic function of the power used to make the light. When you see most of the watch face go almost dark and the important bits being "half brightness", that could be operating at

I’m pretty sure they don’t force everyone to shoot lots of multi camera 4K videos just because the model serves their needs in other ways. About half of the people I help choose phones would be fine with 64 GB, me included. There’s no point

Maybe, let's see… Your N2 is going to evaporate to a gas, cooling your stuff. The heat moved is going to be the "latent heat of evaporation" which is 199kJ/kg. The gas will be at -195°C with a specific heat around 1kJ&#x

A starter pistol with a non-bored barrel is purported to be legal in Massachusetts, so that's an option too. Just don't bring ammunition, that's a problem if it is a type usable in a regular firearm.

Arsenic trioxide was widely used as a herbicide. A typical application would be something like 1 pound/1000 sq feet. ( 50kg/hectare for the rest of planet earth). So dosing a field will take about as big a sack as you can carry an

As someone who learned parsing in the ‘80s I find Packrat Parsing to be an interesting example of invalidated assumptions. Working memory was on the megabyte scale in the mid ‘80s, plus or minus an order of magnitude. Any parsing algorithm

The recommendation when using glyphosate to kill existing plants before reseeding is to wait a week after application before reseeding. I’ve done this seeding grasses, grains, and root vegetables. It works just fine.

About aiming… solar panels want to be installed normal to the sun which means any reflection is going to go back toward the sun. Of course the sun moves around but the reflections are mostly sunward. You’d probably have to have panels in a

Not saying it works, but it is in the ballpark. An idle human dissipates something like 100 watts. Heat and humidity interfere with your mammalian superpowers and you start having trouble getting rid of your 100 watts. A device which moves

Japan has 50% more coastline than the United States. Where I sit, 1000km from an ocean, seafood is pretty remote. Sure, it gets flown in and flash frozen isn't horrible, but it isn't fresh.

My grandparents had one that was a windup bell with two spikes on the bottom and one to stick in the hotel door. If the door started to open the bell would ring. Possibly from the family hotel from the early 1900s.

Picture a US old suburban area as a network of multi lane roads on something like 5 to 10 mile spacings. These roads will be lined with businesses. There will be some area of small shops on the road, some of strip centers. Maybe a big mall.

For rough numbers: The average cost of car ownership in the US is around $9000/yr and 15000 miles (24000 km). So, if an extra $25/day would ruin you, or paying $25/day to go 40 miles (65km) seems ridiculous to you, then you s

According to the inarguable science of taking the first google result for my questions… The sun releases 3.846×10²⁶ watts. The sun has a volume of 1.4×10²⁷ cubic meters. Therefore the sun releases less than one watt per cubic meter. Scannin

I hope the car rental companies augment their trackers to use cellular tower and WiFi access points for location. Then when they detect a jammer they can notify both the owners and the FCC.

Perhaps the type you want would be called “status” instead of bool. Zero meaning success, a few bits encoding severity, and the rest available to identify specifically the error. You would then have a macro or inline called “success” to con
