I have friends with various mobile platforms. Some of them have switched to or from iPhones to Android or even Windows phones. Because of this, I almost never use iMessage any more. The natural tendency has been for *everybody* to rely more and more on messaging apps that are cross-platform, i.e. Whatsapp and less-so LINE. In part because group chats are common. Here in Asia, whatsapp, with its end-to-end encryption, delivery notifications, and the ability to send pictures, audio clips etc. Has become the de-facto secure messaging system to replace fax in a way that e-mail has failed. No platform-specific system, iMessage included, will ever achieve this.
For certain definitions of fraud. The key here is that the DAO contract was badly written. Not Ethereum itself. The 'attacker's open letter on the subject outlines a perfectly good argument. His actions were enforced by the very contract in question, hence there is no fraud.
If two out of phase photons, carrying momentum, cancel each other out and 'cease to exist', what happened to the momentum?
If that, too, ceased to exist, and all the cancelled photons were going in the same direction, it would have a net effect on the momentum of the drive.
The engine no doubt emits lots of particulates, NOx, and sulfur. But that isn't a problem on the open sea. Those emissions are not particularly harmful per se, they only happen to be tightly regulated for cars because they cause problems in cities. That's also why they are not regulated for a lot of other vehicle types.
Southampton isn't the open sea, which is probably why they're glad to see it go, which was the main gist of the article. Here in Hong Kong we have 2 cruise ships in and out daily, the occasional quantum-class cruise ship visiting, several old ferries and lots of Incat diesel-burning ferries that are constantly pumping huge, very visible clouds of diesel smoke into the air. Like 20-stories high before it starts to dissipate. Hong Kong is notorious for air quality problems, and everyone tends to blame it on China, the government tends to blame it on traffic, but as far as I can see the boats are the major pollutors here.
But even worse environmentally. Those aluminium pods are theoretically recyclable, but since they're full of spent coffee grounds you can't throw them in with other aluminium trash, so they get chucked in the bin and end up in landfill. It's a massive waste of energy, as Aluminium takes a lot of energy to produce, yet far less to recycle.
Nespresso "commercial" is the perfect solution. Tamped espresso UFO-shaped pods made of a mylar-like material. Not recyclable but not a lot of waste either.
Whatsapp has been very popular outside the US for a while. I know America was very slow to pick up on SMS/IM in general, but the many benefits of data-based IM include: encryption, sent/read notification, photo message, video message, audio-clip message, all 'free' on Wifi and relatively inexpensive on a data plan, compared to MMS, and in particular when sending messages internationally, which I guess is a lot more common in Europe and Asia than it is in the U.S.
iMessage and BBmessage have the same advantages but of course they are proprietary and only useable between handsets on the same platform. Whatsapp has long been cross-platform.
I think the "micro mask" is the lens array. It already is a light-field camera.
I can't wait to see what these things start to be capable of as technology progresses to assemble the micro structure and we get over the computational overhead
And with good reason. Isn't the whole point of the registry to be able to contact the owner of a wayward quadcopter and hold them responsible for whatever has caused it to be in your possession.
The distinction is drawn at the end of part III. Seems to me to be pure semantics. If the bridge were driven to flutter at a self-resonant frequency then yes, it was a resonant phenomenon. Does causing a wine glass to emit a tone by running your finger around the rim constitute a resonant phenomenon? The variation of the driving force being at the resonant frequency is caused by the wine glass vibrating at that frequency already, as was the variation on the torsional forces on the bridge being caused by the bridge already vibrating.
Resonance is : "a phenomenon that occurs when a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency."
Exactly. Notice the external force part. The external force needs to DRIVE the motion at a specific frequency. THAT is resonance.
The original sentence might be slightly ambiguous but it doesn't explicitly state that the external force needs to drive the motion at the specific frequency. It just says there needs to be an external force, and that it drives another system to oscillate at a specific frequency. I don't know where the sentence came from but I'm curious as to whether flutter is a resonant phenomenon or not.
It's not the orbit that's chaotic. It's the rotation of the moon. It's not rotating around a fixed axis, but tumbles chaotically due to the multiple gravitational forces acting on it.
"A completely new alkaline battery is rated to generate 1.5 volts, but once its output drops below 1.35 or even 1.4 volts, it effectively becomes useless to many devices. "
And yet I can't recall any device that didn't work happily with the 1.2v supplied by a rechargeable NiMH.
They also hate calling something a "terrorist attack" if there isn't a pre-announced political message for the reasons behind the attack.
Well isn't that pretty much the definition of terrorism? An attack designed to instil fear (terror) of potential future attacks against which there is no real defense?
If some random nutjob takes down a plane full of innocents, even in the name of whatever deity and for hate-filled reasons, it's not terrorism unless the reason is clearly advertised and poses a future threat that causes fear.
PS: 'Terror', however, means fear. "War on Terror" is a ridiculous mangling of the meaning of words.
I thought this was common knowledge, or maybe the study is confirming what was long suspected?
Germans have a reputation for being precise, their language is very precise, so it would seem to follow that if one is 'thinking in german' one has to think at a level of precision which far exceeds, say, chinese, which as a spoken language is very simple (tonal complications notwithstanding). Then again written chinese has immense potential for deep poetic meaning due to the recurring use of similar tones and similar partial-characters, which phonetically-written or alphabet-written languages simply cannot have.
Japanese is built with less precision in specification but a minefield when it comes to respect levels. In Japanese you have to *think* in a manner that respects your view of everyone's relationship to each other in terms of seniority, superiority, deference, familiarity etc.
The ones I got flicker too. If you check the teardown vids, some of them have a smoothing capacitor on the end of the driver circuit, which eliminates this flicker. This should be standard imho, but so far the market isn't very well defined.
I ordered a whole load from Aliexpress for around $4 each. Given the expected life of them and the efficiency I thought that was a pretty good pricepoint.
Plus they really are pretty to look at, and dimmable! (you can specify dimmable or otherwise, voltage, and fitting type)
So far the ones I got in 4W and 6W configurations emit light comparable to 40W and 60W bulbs imho, They run cool, barely getting warm after long use. The colour is very nice, much better than the old style LEDs, i.e. without the blue haze. They dim nicely although without changing colour temperature,
The model I got doesn't have a smoothing capacitor though, so they flicker noticeably if you're moving around. I know there are better models but so far it's hard to tell which is which as there are many different sellers on Aliexpress.
I'll admit I'm something of a watch 'enthusiast'. Now, there are a couple of reasons I probably won't buy the iWatch right away, but I'd consider it down the line, especially as more apps get made. It looks quite useful. Now if I find my self wearing the iWatch all the time I'm less likely to want to plunk down for another mechanical piece.
>The Apple watch presents no threat to such Swiss watches, any more than a Tesla >car presents a threat to Porsche.
The fact that the Tesla Model S 85D is about the same price, but is actually quicker than a porsche, tells me Tesla is capable of being a real threat to Porsche, in some model categories now, and potentially all model categories in the near future.
>Me, I think the Apple watch is interesting but it is ten times more expensive than it should be
So are swiss 'luxury' watches. The people who plonk down $5k on a mechanical watch over a quartz aren't going to blink at $349 for a status symbol that's also very useful. Let alone those walking round with $30k timepieces.
>and is not waterproof, and these two facts mean I will never ever own one.
That is a big issue for me, as is the 18h battery life. What good is having your payment system and your hotel key built into the watch if the watch is dead by the time you pay your bill for dinner or return to the hotel at night?
The other issue is planned obsolescence. I can't imagine the level of douchebaggery required to plonk down $10k on a piece of tech that will be obsolete in a year's time. Apple has to at least maintain the form factor and offer upgrades down the line, which so far they haven't stated will be possible.
The rewards offered on kickstarter are pitiful given the risk to the capital, and complete lack of upside if the product is successful.
Just look at Oculus Rift. Sure the backers got "goodies" such as, ooh... prototype oculus rifts, but did they get any of the $2b Facebook bought the company for? No! If Kickstarter were a real investment platform backers should benefit from the success of the company just as easily as they can lose their money when it fails.

That is impressive. I don't think that's the case for most of the world, though. Definitely not where I live.

That's nothing. I should tell you about what happened that one time I tried to pay with a $2 dollar bill at Taco Bell...
