There has been some config languages, like Cue, that are not Turing complete. It is useful of have them always complete and have deterministic evaluation.

Cue also has a lot of schema validation which is better than dynamic languages.

The big problem used to be that people would buy unlocked Baofengs and accidentally use them on licensed services thinking there were generic walkie talkies. The current locked down rules prevent that. They can still get amateur handhelds and use without ham license, but hams police that. It is also easier to get FRS/GMRS handhelds for pubic use, many the same models reprogrammed.

Unlocking handhelds is less of a problem because it requires deliberate action to break the rules. There are fewer people willing and able to do that.

There is also MAP-T which basically does CGNAT with IPv6-only provider network. The local network gets IPv4, the router translates to IPv6 which goes to stateless IPv4 NAT proxy. The advantage is that the proxy is stateless unlike CGNAT. The downside is requires custom code on the router.

Another problem is that Germans went for heavy water reactors and didn't even get as far as prototypes. Americans built graphite moderated reactors and quickly built plutonium production reactors at Hanford. Also, Allies were able to prevent Germans getting heavy water from Norway.

Ultra Wide Band (UWB) has nothing to do with Extremely High Frequency (mmWave). UWB is usually in the 6-8.5 GHz band but with 500 MHz wide frequency, while mmWave is above 24 GHz.

Earphones are the ones that sit in the ear, and in-ear headphones or canalphones are ones that go in the ear canal. Earbuds originally meant earphones but now means both kinds.

Open-ear is more general cause there are ear-hook and clip-on models now.

LA is the densest major urban area in the country. The MSA isn't dense cause it includes all of Los Angeles County which is half desert and mountains. But the built up area beats Chicago and New York cause it has consistent, medium suburban density, 7400 people per sq mi. The others have dense city, New York City is 29,000 people per sq mi, but the far suburbs drop off.

Transflective LCDs, which most bike computers use, are also reflective but have better contrast than eink making them more visible in sunlight. They are different than phones.

eLoran has been proposed as more accurate version of LORAN competitive with GPS.

The Wikipedia page says that China has deployed an eLoran network but I can't tell if used for navigation or just high-precision timing.

Permanent 25th Amendment is impossible. It requires two thirds of both houses which is more than impeachment. Amendment probably shouldn't have provided a mechanism and just required impeachment. Trump would have to be unable to respond or persuaded to resign.

One big reason to use credit card is that it gives window to settle problems. You have month to charge back before have to pay bank. If hotel places hold, it comes out of the credit limit not your bank balance. If someone makes fraudulent transactions, it isn’t your money and you can still pay rent.

If you pay the balance on time, you are getting free liquidity from the bank. But they get if you don’t pay off the balance.

I think you corrected me before. Maybe this time it will stick.

I don't understand why the USB-C module that they are using doesn't include the resistors. Then they can replace the microUSB module with USB-C module and have it work.

USB-C doesn't provide power by default which is better design than USB-A always providing some power. The device needs to signal that it is a sink with 5.1k ohm resistors so the charger can turn on the power. There is also resistor to signal legacy USB charging to work with USB-A ports.

How is the standard supposed to work with defective devices that don't implement the standard?

There should also be training on how to avoid scams. They have gotten so common on the internet and it is easy for anyone to fall for greed or fear. I wonder if being wary about scams would help with cults.

Shopping works better on web sites because can open multiple tabs to browse multiple products. Especially important on big stores like Aliexpress and Amazon where need to compare lots of products. Desktop is better for that but mobile browsers are still better than apps.
