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 m

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 sub

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.

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 wor

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

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.

We need large nation-states to make the modern world possible. The internet isn't just bits; everything depends on stuff that has to be shipped by sea. It takes a hegemon like the US and its allies to keep the sea lanes open. Navies ar

The thing that sucks about Google Music is that they could have merged them but kept the good parts of both. Youtube Music is still missing features of Google Music. It would have been more than "just", but Google Music with Youtu

USB4 includes standardization of Thunderbolt 3. It allows tunneling USB data, DisplayPort, and PCIe. It also adds 40Gbps and 80Gbps speeds. Thunderbolt 4 is profile with USB4 tunneling, 40Gbps speed, and 100W power. Thunderbolt 5 is 80Gbps

Energy density doesn't matter for electricity since the storage batteries don't move and there is plenty of space for them. Cost per energy stored is what matters. Density is important for transportation especially planes. Sodium

Stop saying IPv6 when talking about new protocol. IPv6 already exists and is better than potential IPv4 extension. There was a window twenty years ago for alternative but now IPv6 is usable and can access IPv4 hosts with NAT64. The only rea

An alternate to IPv6 would have been to store the NAT addresses in IPv4 somehwere. But the IPv4 options are fragile and normal NAT would likely destroy them. It would still require rewriting all of the networking and software. It would have

The proper way to do ULA is to generate random 40-bit ID. Then your ULA are likely unique. Which means that if you want to connect or merge with another company, the networks are distinct. IPv4 has a lot of trouble since everyone is using 1

Instead of FAT32, use the flash drive mapping. Flash drive contain mapping from sectors to blocks. This is used to deal with flash erasure, wear leveling, and failures. Custom firmware could map the real filesystem to bad blocks. Does the f

Nobody can agree how big UBI should be, and people talk past each other. Small UBI, like poverty level, could replace welfare but wouldn't be enough to survive on without doing something about housing and healthcare. Big UBI would be e

USB-C is a connector. Part of the confusion is that USB specification versions have come to be associated with the protocols and speeds defined there. The basic division is between USB2 and USB3 which are separate protocols on different wir

USB-C uses resistors to signal the power level for 5V. There is 5.1k for USB legacy, and I forget for 7.5W and 15W. Lots of cheap devices leave out the 5.1k resistors and depend on the same resistors in the USB-C to USB-A cable. It is perfe

One reason is that Lightning couldn't do the faster speeds or extra modes like USB-C. There were USB3 and display adapters but they were sort of hacks. USB-C was used for MacBooks and iPad Pros. USB-C allows passive adapters to USB2 an

Later Polynesians used double-hulled voyaging canoes. Calling them canoe is stretching the word since they were large. We would call them catamarans. But can see the progression from outrigger canoes.
