Not really. Unless the tech company wants to invest in weather satellites showing visible and IR weather patterns, aircraft to fly through hurricanes to gather pressure and wind speed data, ships to deploy ocean buoys to gather water temperature, and Doppler radar sites to gather ground weather data.

The National Weather Service (NWS) does more than just make predictions. They also gather all the data to feed into the weather models and archive the data for later analysis to improve their prediction models. Add in tsunami warning, waterway mapping, fishery monitoring, marine mammal protection and general marine science and NOAA does a pretty vital job with only 12,000 employees.

If Fred&Barney's AI shop says that using data from the NWS, their predictions are more accurate 50% of the time, then they are just guessing and playing the averages.

Not quite. IR only shows temperature differences. As soon as you have more than a single layer of clothes on, the temperature differences start to blend together. Almost all titillating IR photos are of women wearing very thin blouses and no bras, knowing they were being filmed with an IR camera. In real life all you would see is warm spots around the face and general heat zones. Besides, these contacts only show general direction of strong IR sources, similar to what you can already do by closing your eyes and feeling which direction the sun is shining.

Yeah, tinnitus is PITA. I found that having background noise helps distract me from noticing it as much. I use a sound machine at night to help me get to sleep without the constant ringing keeping me on edge. Either a dedicated sound machine or an MP3 player and a looping stream sound are helpful. Other people like the sound of rain or the sound of a fan.

Because tinnitus is so common for military members, the VA put out an informative guide on managing tinnitus. The information helps everyone, not just VA patients. https://www.ncrar.research.va....

People aren't paying four figures for a "course" that can easily be generated with a free chat-gpt account.

No, they are paying for courses from an accredited institution that supposedly has been reviewed and vetted by the college. Using AI in developing teaching materials doesn't invalidate all the information taught in the class. The student will still receive a grade and credit hours for the class, and those credits can be transferred to other colleges that reciprocate credits from the accreditation agency.

If she really thinks she has a case, then she should complain to the accreditation agency, not the college. The accreditation agency might give her a more unbiased ruling as they have no financial motivation to protect.

Matt Parker of StandUp Maths did an overview of the new findings from AlphaEvolve. Some of the findings are very helpful and some are "new ways to pack circles in a box" variety.

The video explains how even a 1% better algorithm can be worth the effort if it translates to less processing needed or more efficient data centers. Worth a quick viewing.

EchoStar has 13 million customers so if EchoStar pays $13 million dollars each year for a licensing fee, divided by 360 million citizens, your 75% would equal 2 cents. That's ignoring the administrative costs to manage the program. Creating a yearly spectrum license fee would just increase the cost of doing business and they would pass the costs on to you the consumer. You want everyone to need to pay a TV tax, a radio tax, a cellphone tax, a WiFi tax, a Bluetooth tax, etc?

The government held a one-time auction to get the big players to pay for a license to use a specific band of the EM spectrum. This would hopefully get the company to actually use the spectrum for their customer's benefit in order to make money to justify the license. If the company is just squatting on the band then the FCC is correct to review the terms of their license. The phrase "use it or lose it" is applicable to this problem.

Comment Another hypersonic vehicle this weekend (Score 1) 13

Russia will have another hypersonic vehicle they will be tracking this weekend, traveling at Mach 26.

The Kosmos 482 Descent Craft will be deorbiting sometime this weekend, entering the atmosphere and slowing to about 150 mph as it crashes to the ground. Where will it hit? That is the big debate. Almost everyone reading this will have a slight chance of being in the decent area, unless you live in the arctic or antarctic. https://www.livescience.com/sp...

Not the same as a low-altitude hypersonic vehicle test, but even the Space Shuttle started at Mach 26 as it reentered the atmosphere from space.

It's funny that most people that claim to be experts have never worked in a federal agency or with federal employees. So many experts don't know what two-thirds of the agencies do so they just assume they must be bloated.

Give yourself two points for each of these government offices you recognize: NIOSH, ORIA, NNSA, ONDCP, and OIPR. If you don't know what an agency is for, how can you state it is bloated and mostly unnecessary?

Stating that CISA is unnecessary is like saying seat belts and air bags just add unneeded weight to a car.

AirPlay devices on public networks, like those used everywhere from coffee shops to airports, would allow direct access.

So that means never connect your iPhone to a public WiFi if you're using AirPods or a smart watch. Imagine a stranger whispering strange things into your AirPods while you sit in a coffee shop. Creepy.

True. This is more of a FYI post so people in accidents can ask their lawyers or insurance investigators to collaborate the speed at which they were traveling, etc.

I had a friend recently get in an accident and the police wrote him a ticket because the other driver stated he was speeding. Knowing there is an independent record of your vehicle data might be helpful.

Comment Event Data Recorder (Score 3, Informative) 71

A cache of more than two dozen police records recently reviewed by WIRED show US law enforcement agencies regularly trained on how to take advantage of "connected cars," with subscription-based features drastically increasing the amount of data that can be accessed during investigations.

Do you know that 95% of all new cars have an "event data recorder" built into them to record key information about the car for a few seconds before a crash? Information like the speed of the car, accelerator position, whether the seatbelts are connected, braking status, and others are all stored in this "black box" inside your car. Accident investigators, insurance companies, and law enforcement can access this information to help during an investigation.

So, how do you know if your car is equipped with an EDR? Their appearance and locations vary widely in vehicles, so it’s important to consult your owner’s manual. Federal law requires that all cars built after Sept. 1, 2012 include a notice in the owner’s manual if a vehicle has an EDR. The manuals for cars built before that date may or may not contain a notice. https://exchange.aaa.com/autom...

I guess unless you are a welder, a scuba diver, or work with liquid gasses, very few people study compressed gasses.

The expansion ratio of liquid hydrogen to gas is 1:850 so liquid hydrogen is very compact compared to atmospheric hydrogen. Also very heavy with the insulated containers, etc. https://en.wikipedia.org/wiki/...

Unfortunately the subject got a little confused when the energy density of compressed hydrogen was not shown. It has an energy density of 7 MJ/L. And because most hydrogen is compressed and stored at 700 bar (~10,000 psi) it means the storage is only about four times as large as AvGas, but compressed gas is much lighter than a liquid. Cars, busses, and some garbage trucks all run just fine using compressed hydrogen, but they don't have as much worry about weight as aircraft.

This is where I get lost in the relative benefits of weight, volume, energy density, fuel efficiency (turbine engine at -60 degrees at altitude) of aerosol jet fuel vs gaseous hydrogen, and so on. I just assume people smarter than me think it is worth studying.

(In a "Look! A squirrel" moment, liquid water to gaseous water (steam) is 1:1700. That is why steam was such a powerful power source and steam condensing back into a liquid can leave a large vacuum which may cause containers to crush from atmospheric pressure. Too many YT videos showing soda cans, 55 gallon drums, and train tank cars imploding to mention.)
