Hardware won't be an issue. Websites may be. U2F refers to both a USB (or BLE, NFC, etc) web format AND a web API you can call from JS. It's the latter that's going away. WebAuthN works with newer and older security keys. So a 2013 original U2F key will continue to work just fine with WebAuthN sites, but there are a number of sites that and some point did implement U2F (the old way) and haven't upgraded to WebAuthN.

Comment Re:Wasabi still has them beat (Score 3, Interesting) 19

Wasabi (and Backblaze for that matter) is in a whole other ballgame.

I have a work project with ~ 1TB of geospatial map tiles. We currently deliver about 9 TB of data a month from that set (a lot isn't that popular). In AWS S3, that's about $800 in egress, $25 a month in storage and around $50 a month in GET ops.

If the project got much more popular... the egress (and GETs) would go up with it.

Wasabi isn't even an option. "If your monthly egress data transfer is greater than your active storage volume, then your storage use case is not a good fit for Wasabi’s free egress policy. If your use case exceeds the guidelines of our free egress policy on a regular basis, we reserve the right to limit or suspend your service." https://wasabi.com/paygo-prici.... We use them as a backup site, sure, but they're not a content hosting site.

If CloudFlare is offering to replace our AWS bill for around $50 a month (current usage), going up a little with GET ops if we got more popular, that's an instant winner.

Sprint/Boost sold and recommended quite a few phones that were LTE in data, but 3G only for voice/text, because Sprint never really got VoLTE reliable enough to switch (and never will, everything is going to the T-Mobile VoLTE network). Saved a few bucks not having VoLTE as an option, I guess. Sprint (and Verizon?) iPhone 5s were in that generation, but Boost was selling cheaper hybrid devices like that through 2018.

Comment Re:So what's the motivation? (Score 3, Informative) 80

From a technical perspective: only in theory are they interchangeable. In the typical urban cable system, there are thousands and thousands of physical devices that amplify signals. In the US in most of them (because of standards from the early 1970s... and honestly the late 1940s) below ~42 MHz signals get amplified toward the company office (or a remote fiber-fed node), above ~50 MHz they get amplified toward the users. So, yeah, if they wanted to replace every one of those diplexers to increase upstream bandwidth, they would inevitably eat a little of the possible downstream (which could be some traditional cable TV channels) to do it. In reality, it's not the lack of frequency space that is stopping cable companies from moving that split higher, it's the cost/benefit of actually rolling trucks to do it.

"Hyundai released a bizarre hype video featuring a seeing-eye robot dog, a nurse robot dog with a tablet mounted on its head that allows the patient to nod at a doctor who is somewhere else, and a teen dancing with a robot in the street. In other words, Hyundai envisions a lonely future in which social cohesion between humans has broken down and robots are our only friends."

So, the purchase make 100% complete sense then. Anyone can look at basic South Korean demographic statistics and figure out what a rapidly ageing population and a 0.85 lifetime fertility rate per woman means in 25 years. No shock at all that Hyundai, Samsung, and LG are all building heavily in this space.

Comment Hydro - where the hydro is (Score 1) 86

We already do this in the Columbia basin cloud zones. But, hydro is just as renewable/non-carbon as wind or solar. There's far more things that would be just fine with 100ms latency than would be bad.

Therefore... Labrador. Goose Bay. All the green power you could ever want from Churchill Falls. If you need more than already installed, there are designs for another dozen large hydro installs in Labrador that just don't have markets currently. All the water you could want (if you even need it). Naturally cool climate. Not bad connectivity (not far from US-Europe cable routes).

Somewhat more advanced than that. There is an elliptic-curve public key and private key generated, then the private key is AES-encrypted on your box by Apple's system. The server you're registering with gets both. To log in, you get all that info, decrypt the private key (hopefully only you can), sign a challenge, and the server you're logging into can verify the signature against the public key. Same principle as a FIDO key.

Advantages: No replay attacks should be possible. And your keypair on site A has nothing to do with your keypair on site B.

Comment Re:Finally, some sane energy policy (Score 1) 241

Nuclear doesn't have to mean a 1950s-design PWR, designed because that's what Rickover was doing on subs, just scaled up. Modern BWRs follow load a lot better. Advanced designs (pebble-bed high-temp-gas-cooled; molten salt) are out there that can follow load as well as any natural gas peaking unit.

Energy is highly relevant to a serious Mars outpost, if it's not just a flag-planting visit. No signs of rich Thorium or Uranium deposits on Mars, but if you're going to shoot it from Earth (or the moon or a possible actinide-rich asteroid), best that you use a cycle that extracts 50% or more of the potential energy as opposed to like 1% (our PWR/BWR light water reactor fleet).

But, to start, there's a lot of Earth-bound engineering still to do. If the DOE doesn't want to go 50/50, the next truly crazy idea would be to find somewhere stable, really remote, that could make use of a whole lot of power (think desalination at huge scale). My thought, if Elon (South African, right) is listening? Namibia's coast. A lot of southern Africa (Cape province, Botswana, etc) needs more fresh water anyway.

Comment Molten salt - maybe a moon shot project (Score 1) 241

I know the DOE has a strong bias toward evolution of current designs over new ideas (even if they're not new at all). Maybe a Musk or Bezos moon-shot billion dollars could help us keep up with the Chinese who are building prototype modern molten salt reactors right now in the Gobi. It would suck to be forced to lease them from Chinese state-owned enterprises in 25 years because we won't invest today. No idea if it's the end-all-be-all solution, but the possible advantages are strong enough as to be worth the effort.

And, yes, we need the power. Elon should know this more than anyone. Right now, the US consumes roughly energy-equivalent amounts of electricity and hydrocarbon transport fuels. So, to get to a mostly electric transport fleet, we'll need to roughly double our electric grid. That's going to take all the renewables *and* nuclear we can build.

I think there's a downside -- a wet downside / backside. How do you deal with that? On the occasions I've used bidets, I end up using TP to pat dry.

Do you get bone-dry on every square millimetre of your body when you get out of the shower? If you do, I could see the issue. I for one don't. I get sorta more or less dry, pull on my undies and clothes which get briefly a little damp and, voila, everything's in an equilibrium dry state within 5 minutes. Same thing goes after using a bidet.

Comment Re:Very few people have 100 Mbps up (Score 3, Interesting) 116

75-Ohm Coax cable can absolutely do 100 up. It can do gigabit up if you like.

The issue is that, on most systems, there are 'diplexers'... amplifiers that amplify in one direction over a certain frequency and the other way below it. And the million-or-so of them in the current networks are mostly set to amplify out everything starting at 54 MHz up to 1 GHz or so. Because 54 MHz was the start of 'Channel 2', as defined in 1948 for broadcasting Amos n Andy in black and white, that's the standard still today.

For technical reasons, this left only a narrow window from ~15 MHz to 42 MHz as workable upstream bandwidth. Which caps out around 35-40 MBps and why you see few cable operators going beyond that.

They've known for about 20 years now that they need to pack downstream a bit tighter, move that 'split' to 150 MHz or 250 MHz, and they can accommodate Gig-plus down and near-Gig up speeds. But, it's expensive (all those pole-mounted amps). They're too busy counting their profits. So, 20 years on, few have done it.

It's not that current 1000/35 Coax or 55/15 VDSL services would become illegal or anything. But, I kinda have to agree that we shouldn't be spending Federal dollars for subsidies to build out anything short of GPON... considering that was already a developed standard and in regular deployment 12 years ago.

Comment Small local cable cos are already dropping (Score 2) 35

Had my wife's aunt ask us about streaming TV options rather unexpectedly. Because their rural cable collective dropped TV service altogether (see https://www.sktc.net/tv/) because they just weren't big enough to fight the agreement negotiation fight any more. Interestingly, because she's outside effective antenna range of her primary market city (in the digital/ATSC era), it's made the big 4 networks the very hardest thing to get.
