Except that Tesla (and Smarts, and the few other cars which use batteries manufactured by Tesla) use *the exact same kind* of battery cells as regular laptops (on purpose, because they are cheap and easy to source due to the economy of the scale at which they are produced).
No, they purchase custom cells. Being Lithium-ion, they are certainly similar, and Tesla does not publicly reveal what is custom, but they are not the exact same.
They are super expensive, and I have yet to see any battery tech that lasts over 4 years, and normally it is performing far worse than optimal at a fraction of that time.
Actual tests on actual used cars (by Consumer Reports) demonstrate that what you say is unequivocally wrong for the batteries used in EVs and hybrids. No, the ones in our notebooks and phones don't last so long, because size and weight are more important than lasting 10 years. Cars are designed differently, for different longevity/size/weight tradeoffs than are portable electronics.
It's NOT trying to burn the school down. That's the act of an adult, 15 years old or not.
But he DID NOT try to burn the school down. He did something stupid and childish, which could have burned the school down only if he had been extremely unlucky--huge difference, and judgmental pricks like you who like to conflate what "could have happened" with what "he tried to do" in order to justify your self-righteous and indignant attitudes, who are responsible for the epidemic of ridiculous zero-tolerance policies in schools.
On the prior article before the announcement, I posted about the economics not being that compelling, using my own actual numbers for consumption and peak vs off-peak pricing. I also noted that in some states, CA in particular, when peak pricing is ~60% higher than where I live, that it could start to be somewhat attractive.
That was all based on the pre-announcement rumored price of $13,000 for 10KWh. At $3,500 for 10KWh, I'd be looking at a 4-year payback, or, in other words, about a 25%/year ROI. To be clear, that's without solar PV panels to generate electricity, that's strictly charging the battery during off-peak hours and then running the house on it during peak hours. (Quick calculation based on battery price alone; total installed system more likely to see 15%-20% ROI, but still, not bad.)
I had wondered what Musk was up to and if the rumors were correct. Because you can already buy a 10KWh nickel-iron battery system for $13,000, so it did raise the question of what was the point? Well, now we know the point--1/4 the cost of existing competitive systems.
One big question not answered by the linked article, is what technology is used and what's the depth of discharge without damaging the battery. With nickel-iron, you can discharge most of the charge safely. With lead-acid technologies, you can't go below about 70% without shortening the lifespan. So 10KWh can actually mean anything between 3KWh and 8KWh of usable power--a huge range. (Hey, maybe Tesla's going to be consumer-friendly here--maybe 10KWh means 10KWh of usable power... As this kind of thing becomes more common in the home, it would make sense to rate battery systems that way, to make direct comparisons easier...)
For example, if I donated some money to Exos Aereospace above and they developed a revolutionary rocket that makes the founders billions, why can't the people that donated have a slice of the pie?
SEC regulations. There's a high bar, in terms of regulations and documentation, for selling equity to the general public.
The SEC is actively working on reducing the burden precisely to allow small investments via crowdfunding, but I haven't followed their progress.
Since most people who will be subject to ransomware have no way of knowing the mechanics of the encryption (or wouldn't be able to access it anyway)... does that they lied about their super secret crypto make a damned bit of difference?
Well... IF the tool becomes widely-enough known, that when a victim goes looking for some tech to help them, then it could be very useful. As opposed to real public/private key encryption where no one could legitimately help them.
I doubt this will happen; I doubt the tool will be utilized; but it's at least been made possible now. (And of course, new versions of the malware will keep popping up...)
No. Of course you need one if you want to use the App Store, but it's certainly not required to use the phone. So, when you have no clue what you're talking about, maybe you should keep your mouth shut instead of making shit up;-)
But if you are in a place that has a couple shorter power outages every year and where thinking of getting a few more UPS-s and a standby generator, a large battery suddenly could be economical.
So, for $13,000 up front, I can save at most about $80/month, maybe less, depending on the particular battery technology and how deeply the batteries can be safely discharged. (Yes, I used actual numbers.) It's a first step, but assuming that the capacity is 10KWh as mentioned in earlier articles, it's not really any cheaper than existing solutions. Now maybe Tesla will ramp up capacity and make them more available, or maybe it will actually be higher capacity, or maybe the price will come down substantially as volume increases. Because at 1/2 the $/KWh it would start to be really interesting, but right now, it's kind of marginal--at least for me at ~$0.15/KWh peak; obviously, in a state, CA for instance, where peak power prices are higher, the economics are better.
So, it will be totally impossible to create software to decrypt these video streams? They now have an algorithm which can be implemented in hardware, but not in software? Yeah, right...
All in all, every time I see an SUV on the road I have to assume that the driver is a huge jerk, because only a huge jerk would choose to endanger other people's lives just for the sake of their comfort and convenience.
Well, maybe that's kind of true in San Fran... But there are places (and times) in the world that when you see a Prius, you should assume that the driver is a total moron...
The original HIPPA law was called the "HIPAA: Health Insurance Portability and Accountability Act" but the portability never happened.
Sure it did. We've had portability of health insurance for a long time now--where portability simply meant that once you had health insurance, you could keep getting it...
You're the one who is ignorant of the issue. I deal with it all the time. And, frustrating as it is, I, unlike you, am aware of the history of the various attempts, and the reasons they have failed. Primarily, you have absolutely zero concept of the overwhelming complexity of the data involved, how rapidly it evolves, and the cost to society if we retard that evolution via regulation. (The example I gave was a deliberately simple one, the simplest imaginable, so that anyone could understand it.)
And, oh, by the way. There are standards for the simple little things you mentioned in your initial post--reluctance to connect to those devices is rooted at least in part in fear of regulations. But those simple little things are the tiniest most infinitesimal part of what a universal data standard would encompass.
In the miasma of bullshit jargon that permeates this industry, an Electronic Medical Record is that thing your doctor uses to keep his records about you. An Electronic Health Record is that mythological thing that contains your complete life-long history and is shared--instantly, seamlessly, yet with complete privacy protection--between all your medical providers.
However, long outdated programming practices is the norm in EMRs.
Long-outdated programming practices were traditionally merely the norm in EMRs. But now thanks to subsidies, Meaningful Use requirements, and certification procedures, they are effectively mandated by the federal government.
Really? And let's say that instead of a normal adult visit, we're talking about a pediatric visit for a child or infant with a congenital heart defect. Will the oxygen-level gauge transmit whether the reading was from a finger or a toe? Will the manometers also transmit: 1) what side the pressure was taken from, 2) whether the pressure was taken from the arm or leg, 3) whether the patient was sitting, standing, or supine?
Yeah, that's the thing. When the/. crowd starts saying there should be a "single standard" for medical records, those of us who actually work in the industry just roll our eyes... You have no idea of the complexity of the problem, nor of how fast things change on the cutting edge of the specialties.
...but I'll bet that there's almost nothing concrete in them about usability.
It's worse than that: 1) There's not even anything at all regarding usability, not even the most vague amorphous pablum; 2) Many of the regulations have the unintended side effect of pushing things toward poor usability.
In the case mentioned, the patient suffered permanent damage because he did not receive appropriate care. It doesn't really matter whether it was the doctor, or a nurse, or improperly maintained equipment, or a frickin' janitor's laziness, or the EMR--the hospital is responsible for providing appropriate treatment to patients.
Yes, I'm sure there's a small number of sleazy lawyers who will latch onto harmless mistakes in the EMR to try to invent a case where there is none, just as they have always done with all mistakes, long before EMRs existed.
But the real problem is not the lawyers. The real problem is the byzantine UIs of these monstrous "Enterprise Medical Record" systems, if you get my pun;-) After all, some data entry mistakes do cause actual harm.
At least Europe is going to get something now - not my personal favorite (if there is anything interesting there, which we don't actually know, it's buried way too deep for us to get at it for a long, long time).
If you're really that curious about what's in Europe, why don't you just visit the next time you take a vacation?

isnt survey monkey the ads that were all over everything back in the early 2000s that always led to malware??? or am i thinking of a different group
Yes, you are thinking of a different group. SurveyMonkey is an online app for designing and administering and analyzing surveys.
They are super expensive, and I have yet to see any battery tech that lasts over 4 years, and normally it is performing far worse than optimal at a fraction of that time.

Not by me. Nor by anybody else here on /. that I can remember.

You don't need an Apple ID on an iPhone?
No. Of course you need one if you want to use the App Store, but it's certainly not required to use the phone. So, when you have no clue what you're talking about, maybe you should keep your mouth shut instead of making shit up ;-)
*Exactly* like people who get itunes & apple store for no reason other than having an iphone... Why do people rage about this but not about iphone?
Because it's not true ;-)
After that it starts to feel kind of disturbing.
But if you are in a place that has a couple shorter power outages every year and where thinking of getting a few more UPS-s and a standby generator, a large battery suddenly could be economical.
Good point. Especially about the generator.

IRAs can have a MUCH larger ROI than any 401k. It's not my fault you were stupid with your investments.
If you have a decent 401(k), you should have a similar range of investment options, with similar costs.
Your ignorance of the issue is appalling.
