The argument is "a human safety driver will never be perfect, so use something more appropriate or don't test in situations where you can hit anyone". If there is no suitable substitute for the ineffective safety driver, then work on that first. If that means not testing on public roads, so be it. If that means setting up a simulation town with people who are paid to be there and test the reactions of autonomous vehicles, so be it. Nobody said it was going to be cheap or easy.

Electroweak unification IIRC occurs at roughly 264 GEV where electric and magnetic unification is a consequence of Maxwell's equation and just the consequence of moving charges/changing fields.

Uh... they pretty much have. And the fact they offer an 8 year unlimited mile warranty pretty much says they are not worried about batteries failing at all.

On what basis do you think this will successfully treat the problem? It may require sleep under gravity. The astronauts, now, have rigorous exercise regimes to treat the _known_ problems. What makes you think that this regime will help?

Well, that bunch of wilfully ignorant executives at Apple Inc. decided that they know better than an entire field of educational developmental psychologists who could've told them that coding for 3 year-olds is a really stupid idea & a waste of everyone's, including the 3 year-olds', time.

Any why haven't the journalists reporting on this news called any educational developmental psychologists? Wouldn't that be a bigger headline & attract more views?

We need journalists to call out bullshit from EdTech companies because they distort our education systems & cost huge amounts of tax-payers' money with little or nothing to show for it. Yes, some EdTech can help students to learn but you have to test it out in controlled trials to find out before selling it to tax-payer funded institutions for hundreds of millions of dollars at a time or in billions if you count California.

From the beginning of the space age, there were doctors around claiming that disaster was right around the corner. No matter what they had predicted wrong, they came back with another dire prediction that was just beyond current experience. That would get disproved, then another, and another, and another. People use to warn against the danger of going the breakneck speed of 15 mph in a steam engine.

This is just more of the same. Bloot clots happen all the time, it's a real problem with long airplane flights, so space isn't even part of the problem.

So just install linux and embark on your career as a kernel compuler?

Stoot should just shitcan Slack and bring back Tiny Speck. A bunch of us miss playing Glitch.

Well to be fair unification of the electric and the magnetic is not a consequence of being above an energy threshold. If you are a fan of GUTs they all unify at high enough energy.

Phone batteries get charged to almost maximum capacity, so much that any more may let them burst into flames. And sometimes that actually happens ;). Also they are allowed to be discharged until they are on the point of unsalvability (you can ruin your Li* batteries by discharging them too deeply). And that all in sometimes abominable conditions (too hot or too cold... too fast). This probably is because in the eyes of regular consumers, time for 'untethered' operation, fast availability if you have to charge and 'just f***ing charge' even in bad conditions is more important than battery longevity.
In proper EV's the temperatures and charge rates of the various cells is very much regulated and batteries are charged and discharged with sometimes dozens of percentages to spare. This means if your EV stops at the side of the road due to 'empty' batteries, it may only be 80% discharged. The same for refusing to accept charge when they are not yet 'completely' full. This increases the usable life of the batteries tremendously. There may be emergency modes or firmware unlocks that may give you access to more range... you will hurt your batteries with those 'though (I'm not talking about locks that make an EV seller market a cheaper model with less range but essentially installing the same batteries. There are those too).

Without the mockery of black holes, the concept of spacecraft large enough to spin for gravity, and to sleep under even modest gravity are quite old. It is _expensive_ and carries very real danger. The spacecraft have to be much stronger, much more massive to be stronger, and typically much larger to avoid Coriolis force disorienting scientists.

Not all Gen X, nor all Boomers, nor all Millennials are the same. Your diatribe conflating entire generations as if they don't contain unique individuals isn't consistent with reality. For example, I'm part of Gen X and many of the politicians I disagree with are Boomers who some famous Millennials love to support.

You can't compare Windows and Linux. Windows is a proprietary OS based on code that has always been proprietary and the development model is antiquated. They also have only the people who can't develop quality code working for them. All the real talent works on quality code and would never touch the pile of dogshit that is Windows.

Chipsets have nothing to do with it since all Windows platforms that matter run x86, and the Linux kernel has over a 1000 config options at build time for each given kernel version whereas for each Windows kernel version the builds are virtually identical. There is almost no heterogeneity in in Windows in relation to Linux.

"If you find a bug in one of the software or libraries (Apache, MySQL, Cassandra, OpenSSL, OpenSSH...), you can infect multiple platforms."

DAC makes this approach much harder with Linux. You can try to argue with me all day, but here is what you can't argue with: Windows malware infections are pervasive and they are almost unheard of on Linux while, for example, they still don't know how - or even if - any machines have been infected with this code on a Linux system

I've got an Audi with a 4.2 V8 that has like-new compression, and the cylinders are still literally as smooth as a drinking glass. The valves are still shiny. It's got 225k miles on it. Granted, it's got an alusil block. Also, it has to have a timing belt (etc.) every 90k, and getting the same mileage as new means it only gets about 18 MPG combined, so there's still clear advantages to EVs.

This is not good and really a serious possible health problem.

I can see other people saying that this can be fixed with rotating structures providing simulated gravity but there's literally no studies done on living at acceleration levels less than 1g other than the expected initial dizziness that will occur until the body adapts to continually rotating (yet another unnatural state for the body).

I'm very pro-space, but clearly a lot of work needs to be done to a) understand all the issues human bodies and b) develop environments in space where humans can thrive before we can consider multi-month/year trips to Mars and other planets.

Mkay. I'm offended unless people use Mkay.

Should've been May 4... What a waste...

Midichlorians.

The astronauts do get exercise on a daily basis. Apparently it doesn't prevent this particular problem. Most likely because in space, unlike on earth, no amount of moving their limbs changes their orientation relative to a gravitational field.

It may be worth looking at zero g exercises that involve more rotation to see if that might be enough.

Not unless it breaks. Otherwise it burns away over time and becomes less restrictive.

Two good pulls breaks in an engine. Literally.

I think it is because a lot of them were raised with the concept that words hurt terribly, and if someone says mean words to them, they need to go into therapy or on antidepressants.

So perhaps many of them think that if they throw an "Okay Boomer" at someone older than them, it injures or enrages us in the same way. Hell I'm called an asshole at least three times a day, and I just chuckle. "Okay Boomer" doesn't even register other then telling people they need better insults.

I am certainly encouraged by every advancement in electric car design but it seems many people are so caught up in the electric car that they forget the ultimate goal. What is that goal? Lowering CO2 emissions. Electric cars will forever be hobbled by the limitations of the chemical battery. Electric propulsion of vehicles of all types has allowed for just phenomenal advancements in the capability and efficiency of vehicles. This is perhaps most apparent in the railroad locomotive as nearly every locomotive in existence today has a diesel electric drive train. Ships of all sizes are also utilizing the electric propulsion, with the electricity provided by a diesel engine, a gas turbine, or a nuclear fission reactor. What we are likely to see is this shrinking of this diesel electric propulsion model to the common passenger car because of the capability, efficiency, and simplicity of the drive train.

Again, this is because batteries have some inherent limitations that cannot be ignored. It's certainly pleasing to see chemical batteries reach new levels of operational life as this has implications for not only transportation but also for personal electronic devices, power tools, medical devices, and so much more.

I'll see people claim that we will see electric planes carry passengers "any day now". Nope, not going to happen. Not only are there technical challenges but also regulatory barriers. This also goes for ships, buses, and any other vehicles that currently predominately burn diesel fuel, gasoline, or kerosene. The switch to batteries for their store of energy for propulsion will be slowed by technical challenges and regulatory barriers.

So, what is the real problem here?

The problem is not the engine itself. The problem isn't even the fuel. The problem is where the fuel comes from. The fuel we burn is dug from the ground and when burned introduces CO2 into the air where it contributes to global warming.

Perhaps instead of trying to upend the entire transportation infrastructure, by trying to wedge the electric car into a hydrocarbon fueled system, we spend some effort in finding a new source for the hydrocarbons.

We had had the technology for decades now to synthesize hydrocarbon fuels. This process has been used for a long time to create lubricants to high standards but this has not been practical due to costs to use to make fuels. Not because we don't know how, but because few have considered this practical until fairly recently.

The US Navy has been working on perfecting this technology for a long time, begging for funding on their fuel synthesis process from Congress and from private investors. It appears that they are very close to making this happen. This is a system they propose to put on aircraft carriers to use the nuclear reactor on board to produce the fuel necessary for the aircraft it carries. Since it uses carbon and hydrogen from the environment this fuel is carbon neutral. There is no reason this technology has to remain on a Navy ship and only to fuel aircraft. The process can produce any hydrocarbon, and so can produce methane, propane, octane, cetane, and anything in between.

This is what will bring all of our vehicles to become carbon neutral, synthesized hydrocarbon fuels. We will still likely see a shift to more nuclear powered ships, electrified railroads, and even battery electric cars, but for everything else it will be synthetic hydrocarbon fuels from nuclear power.

At a minimum we will have to consider where the electricity comes from to charge these electric cars. This will have to be electricity that has low CO2 emissions, low cost, is plentiful, reliable, and safe. This means onshore windmills, hydroelectric dams, nuclear fission reactors, and maybe some geothermal power. That's what the future will look like. The future is not batteries to power every plane, train, and automobile.

Smartphone batteries use cheap chemistry.

You do know that you are a prejudiced bigot don't you? Stereotyping anyone born between 1946 and 1964 of the exact same mindset and political outlook.

People in the KKK think they are right. People like you do as well. Neither of you are right.

Fortunately, we owns all the guns to keep you in check, pal.

Even Windows has more than 3 platforms these days between various flavors (Home, Pro, Enterprise, European, Education, Server, DataCenter), various chipsets (x86, x86-64 and ARM) and various supported versions (7, 2012, 2016, 10, 2018) yet malware infects all of them at once all the time.

If you can find a bug in the Linux kernel, you can infect multiple platforms. If you find a bug in one of the software or libraries (Apache, MySQL, Cassandra, OpenSSL, OpenSSH...), you can infect multiple platforms.

So obvs they don't want any space births until they study it more, but what is this going to solve? You blew your wad in the rubber and now it has the consistency of silky milk instead of watery, expired fresh mozzarella?
