I was surprised by the .36. When Lexus first came out c. 1990 they advertised the LS400 heavily as having a .28 and later models got down to .24. .36 is 50% worse than a 1990's sedan and surprising since range has always been an issue.

I guess it looks cool, though (hard to argue with the company's success).

You're missing the part about where this is a roadster. Convertibles have considerably more drag than cars with roofs. Also, you're only looking at Cd. Cd is used in the drag equation to calculate total drag, and the part that isn't part of Cd is surface area. The lexus vehicles have much higher total drag because they're all much bigger cross-sectionally. The Tesla Roadster is tiny.

Oh dear. I guess your browser doesn't render the humor or sarcasm tags properly. The parent comment was intended to be snarky humor poking fun at those of us who think the gpl is a good idea. Whether or not it was actually funny is debatable of course.

With a user number about the same as mine, you have spent enough time on the internet to realize that sarcasm generally doesn't communicate well through plain text. No matter how outlandish and stupid you think your sarcasm sounds, I guarantee you that there is a significantly non-zero number of people on the same forum who are actually stupid enough to post in earnest what you posted sarcastically. So you shouldn't be surprised when people take your sarcasm as stupidity in earnest.

Fitness sensors and apps seem to be a common thing to put into phone/watch these days, but how useful are they actually? I do plenty of sport (jogging, cycling, playing hockey) and have done so over the last 20 years, but at no point in my life have I ever thought "Wow, I wish I knew what my pulse-rate was right-now!". It may be of use to professional athletes, but to the normal person who does exercise to keep fit or for fun, knowing your pulserate etc is pointless. To me, cramming these fitness sensors into phones and watches is a solution in search of a problem.

Having a portable device track your heart rhythm as well as your heart rate could be of great importance. My aunt suffered a massive right middle cerebral artery stroke, caused by a previously unrecognized atrial fibrillation. If she had some device that could have warned her that her heart rate was irregular, she could have avoided this crippling, life-altering event that has left her unable to walk normally or speak more than one or two words at a time.

the expert believes iPhones, iPads, OS X, other RADIUS servers besides freeradius, VoIP phones, printers, and various commercial managed wireless solutions could be affected

Nowhere on his page does the researcher say anything remotely like this. It's a really bad interpretation as he does not list any VoIP or printers or Apple products. Specifically to be vulnerable to this attack, the product must use a vulnerable version of OpenSSL. Certainly Apple does not use OpenSSL and there are other products that do not.

If you post about a vulnerability and forget to mention the word "Apple" (whether or not it's even relevant), you just gave up tens of thousands of clicks.

Unfortunately, non-profit hospitals are, in many cases, a sham. Yes, the "hospital" is losing money, while all the doctors working there are pulling in substantial incomes at the same time.

Are you suggesting that those doctors, nurses, technicians should all work for free?

Regardless, what the physicians make has little to do with how the hospital fares. In the US, hospitals rarely employ physicians. Hospitals are just one of the places where doctors go to take care of patients. There's usually little financial linkage between the two.

Actually, it's in direct contrast to other research that said most people with iPhones had a lower income than most people with Android phones: those who can afford it the least sometimes tend to buy the most expensive stuff based. But that was a few years ago - perhaps it has changed in the mean time.

Gonna have call BS on this one. I need to see a link for this assertion.

I do, I sometimes don't claim back charitable donations. I don't claim depreciation on my rental property I do not think it is valid expense. I claim deductions that I believe to be fair and for business purposes, I do not claim ones i don't, legal or not.

But the real reason is probably everybody could get away with paying less tax if they knew what they where doing. The reason normal people don't is it is not feasible for the average person to pay millions to an accountancy firm to set up tax shelters. Once a company starts making billions however those admin costs become insignificant.

Why couldn't you set up a company in Ireland and contract out of that instead of being directly employed by your company. (they would think you where dodgy but only because it isn't common practice). Your employer is paying you the same amount, what difference does it make to them. The hassle is just not worth it, at least for the common man.

The problem is that you don't have stockholders that will sue you PERSONALLY if you pay more taxes than you have to. Public corporation executives can be personally liable for intentionally harming the financial standing of the companies they run.

The fingerprint is saved locally and encrypted on the individual phone's A7 chip. Never goes to iCloud. Never touches Apple servers.

Do we know this for fact?

Do we really know anything for fact? If your tin foil hat is sufficiently snug, you would not believe anything at all about anything. Apple has a history of exaggerating or selectively picking performance metrics, but not out and out lying about privacy and security features.
