Comment Re:"Average" bomber. (Score 1) 75

I was just reading this comment on another social site:

"Any statement that starts with "No one would be stupid enough to..." is false."

There's probably too much metal between the cargo hold and the passenger compartment for Bluetooth to work anyway. I think all actual bombs on aircraft (other than the failed shoe bomber) have been triggered by pressure switches at altitude or timers.

So it's not just that they wouldn't be stupid enough, but also that it probably wouldn't be successful even if they were.

What is "very large"? How far is the faucet from the water heater? Couple hundred feet? I've never seen anything take *minutes* to get hot water out. Hell, I can turn my boiler on and heat the whole tank from cold faster than that.

My house is a relatively normal size (1800 square feet), and it still takes more than three full minutes for water in my shower to reach full temperature when I run it straight hot. If I also turn on both faucets in my bathroom, I can get that down to about twenty or thirty seconds, which is barely tolerable.

At my mom's house in Tennessee, the distance the water has to travel is comparable, but it takes only ten seconds or so.

It's a huge downside to all the water-saving showerheads and faucets that were forced upon us here in California decades ago. We waste a lot of time and energy to make up for a water shortage that exists only because of decades of politicians being short-sighted and kicking the desalination can down the road over and over so that the money doesn't get spent on their watch.

Who in fuck is Grundfos?

"Grundfos is a global leader in advanced pump and water solutions, renowned for its highly efficient, reliable, and sustainable pumping systems."

Ah.

Translation: A company that has the potential to benefit from regulation by squeezing out competitors wants more regulation.

I'm not saying they're not right, just that it seems awfully convenient for a company specializing in pumps that recirculate data center water to want efficiency regulations that would push customers towards their most efficient (and thus presumably most high-margin) pumps.

Why does your water heater need a pump?

Instead of having your hot water fan out in a tree, you wire it like a token ring with a return pipe, where each faucet only has a short bit of pipe between it and the ring. Then, you have a pump to circulate hot water through the ring-shaped pipe network. That way, it takes half a second to get hot water instead of half a minute or more.

Depends on the exact wording, but Android Open Source Project (ASOP) is not shipped on many devices. Most ship with Android, which includes Google Play Services and a load of other proprietary, closed source stuff. So presumably they would need to implement these controls, and I'm sure Google will oblige by offering them to vendors. In fact even if they were not mandatory, I expect vendors will market it as a feature and want to include it anyway.

Sure. I'd imagine most hardware vendors will want it. I'm just saying that the wording, at least as described in the summary, is... problematic at best.

This would be like requiring every single restaurant and fast food place to check photo ID because somewhere in the entire state a bar exists where you have to be 21.

Not really. It's more like requiring all vendors who sell cash registers used in restaurants to support checking photo IDs because some restaurants also serve alcohol.

Because, it's California, and the Governor and mayors can't put the responsibility for actually taking care of their kids and making sure they aren't on a website "that could be dangerous".

There's no safe way to prove your age to a website. Any scheme requires trusting some arbitrary third party that could secretly be the government doing timing comparisons between the verification and DNS queries and stuff to unmask anonymous users. At least with operating system or browser vendors, they presumably have a strong commitment to minimizing the risk of someone publicly posting "John Doe just visited sexwithseaturtles.com" or whatever.

Comment Re:Good laws need no exceptions (Score 2) 124

Age-verification at OS levels was always a terrible idea. It's difficult to see under what rationale Linux should be granted an exception for this dumb idea. The solution is just to repeal the law and flog the sponsors.

It's not really that terrible. If you're going to do age verification, you have two choices: browser or operating system. All else is all but guaranteed to be either a privacy disaster, a usability disaster, or both. And either way, every operating system needs to support multiple users, or the "I used dad's iPad to browse porn and buy firearms" problem makes the verification useless.

And major operating system or browser vendors that cater to the general public should make it available by default, because doing so prevents the "You downloaded the AdultCheck module, so you must be a pervert" logic that some people might use to attack people.

What's terrible is the idea of mandating that it be performed at the OS level, rather than just mandating that the OS doesn't get in the way. Browser-level verification is actually far preferable, because there's no need to bake that into an authentication framework when you can just send it out to a browser window. Leave that tiny bit of integration complexity to the companies that actually require it. But this only works if the OS supports multiple users, so that the browser's cookies and storage are not shared across multiple users.

For devices that don't have multiple users, baking it in at the OS level really is the only way, but it could just as easily be solved by baking it in at the browser level and changing the OS to allow multiple users per device. Unfortunately, such technical details are way too subtle a point for most lawmakers to understand, so obviously they did it in the most wrong way possible.

This should not be acceptable. Carve-outs are always temporary. Always. Do not give them an inch.

Wait 'til they realize that Android is distributed under a license that allows people to copy, redistribute, and modify it.

As usual, a law created by people who didn't think of the consequences then got modified to fix some of the worst consequences, but because they still did not think of the consequences, the modification created different consequences. And this is why we need better lawmakers.

Europe is Dumping Windows as fast as it can - on security grounds. Europe does not have the American funding model, and many start-ups are individuals with no significant funding.

I have developed many Xilinx projects, and failed to develop many more because I could not afford the development software. Including military applications that could have run to very high volume. At that time, there were no realistic alternatives.

I've seen some people who claim to know what they are talking about say that the thermal emissivity scales by the fourth power, so the hotter you let your satellite run, it scales considerably.

I'm not a physicist, but that would make sense -- the hotter you are, not only do you emit more light, you also emit a broader spectrum. If that wasn't the case, I think the sun could be infinitely hot and would only emit infrared. Or to put it another way, the more thermal energy you have in a system, the more it wants to dissipate. Ties into the second law of thermodynamics.

Maybe, but the problem is that the electronics have to run at those temperatures and not have solder joints start popping, or other fun failures.

My guess? I doubt it saw or recognized the intent of the hand gesture, but it almost certainly recognized the flashing red. I assume the "thought" process was "well, nobody else is going. We all stopped at roughly the same time. Yeehaw." but who knows. Doesn't Tesla have some sort of "playback" feature where it can show you what it saw? Or is that only a real-time view?

As far as I know, it is just real-time. And it didn't even slow down at the flashing red light. So either it recognized that someone was waving it on or it didn't see the flashing light at all.
