Newspaper articles are written so that all the most important information is set right at the beginning.

> This is why we are still waiting for Perl 6, if it ever gets released.
I suspect in the case of Perl 6 (and perhaps also for Python) it may have been better to give the language a new name, and allow even more radical changes. Keeping the name strongly signals that it's still the same language. Breaking compatibility is exactly what makes it a different one.
So.. preserving backwards compatibility and interoperability across versions is a bad thing? If he's unhappy with the feature set of C++ (and I wouldn't blame him for that), then how about simply picking up a different language instead? That's what a new, non-compatible C++ version would be in any case.
Look at how great it has worked out for Python. It's been six years since the only mildly incompatible version 3 was released, and it has still not managed to become dominant over the legacy version 2. A more radical break would almost certainly have had an even tougher road ahead.
If there was a geniune shortage, you'd see sharp increases in salary levels. There's just a shortage of qualified people willing to work for much less than they're worth.
From Alfred Nobels will: "[...]which shall be apportioned as follows: one part to the person who shall have made the most important discovery or invention within the field of physics; [...]"
So, discovery or invention. Doesn't have to be fundamental science, and can indeed be a pure engineering achievement.
That piece is kind of crap. The main reason is that the summer holidays are over. The kids are in school (and busy with clubs, homework and so on on the weekends) and the parents are working. And as most bathers are gone, so are the drink vendors, the equipment renters and so on.You'll still find people on beaches, just not many.
I would imagine that this will be the kind of a movie that will be in the five dollar bin at Walmart's within a month of release. And there will be a lot of them that simply stay in that bin.
"Indeed, in Japan, only the western half of Honshu, Shikoku and Kyushu have enough sunny days to justify large-scale rooftop solar installations."
Which is why one of the largest solar plants opened near Sendai in northern Honshu a couple years back? What conditions are profitable depend on the technology you use, and the cost of production. And as solar cost decreases and efficiency increases more locations will be realistic.
There was some seismic activity for a period of time before it happened - but this is Japan; there's always seismic activity happening. According to interviewed researchers there really was no warning beforehand.
The video is deceiving; that trail is much steeper than it looks. Slowly stumbling downwards is pretty much all they could do. Also, most deaths from eruptions are either from poisonous gas or from heat. A small hut will shield you from neither. But both gas concentration and heat will disspiate by distance, so simply trying to get away from it may well be your best chance to survive.
So why are people generally using quadcopters for autonomous systems? What's the disadvantage of a single-rotor copter when you're doing autonomous flight? I can imagine that perhaps it's a size issue - quadcopters are lighter or cheaper or more efficient below a certain size or when indoors? Or is it much more difficult to write a reliable control system for a single-rotor system?
* 65 km/h peak speed, and will cover the distance in about 15-30 minutes; * It weighs 5kg, and can carry a payload of up to 1.2kg
With 1.2kg it can certainly carry a complement of medicines or even small, urgently needed hardware and parts (batteries or spare bits for medical equipment for instance). Not general use of cours, but it does look like more than just a stunt.
Why? Maybe I simply only review things I like. Why would that devalue my reviews?
This. One reason really low and really high reviews are much more common than they ought to be is that people only bother voicing an opinion if they feel strongly (positive or negative) about something. Another is that once they do, they'll tend to exaggerate their evaluation to really drive home how they feel.
My suspicion is that the only stable scale is a simple "really liked it/really disliked it" up/down system. Then somehow weigh that according to the proportion of customers or buyers that actually bother to review. That depends of having a decently good estimate of that proportion though. The likes of Amazon have that for their products; for restaurants it'd be hard to impossible,
Charlie Stross recently posted a very good take on this: This is a permanent change. Whatever happens during the first few years is basically irrelevant, compared to the long-term results. Did Norway separating from Sweden cause short-term economic upheaval? Does that matter at all a century later?
This is a long-term change, not a short.term one. Any voter should consider the probable situation twenty or fourty years from now, not whatever happens in a year or two.
"Also some of the science and tech courses are very demanding but the teachers don't simplify it leading to many whooshing sounds for the student throughout the courses. Such courses could benefit from a simplified overview of the course material."
How many employers would like to hire people that can't understand the actual content and need "simplified overview" to get a grade? If you really don't grasp it to the point where you can actually apply the math for new, novel problems, then you don't actually know it, do you?
MOOCs have a serious credibility problem already. The very last thing they need is to dumb things down. If it becomes common knowledge that, say, an engineering MOOC graduate can't even handle a system of differential equations in an intelligent manner, or don't understand the implication of Green's function, then the credits will become truly worthless.
It does depend on the size of the field as well, though, as well as the funding. I can well imagine astronomy having major problems; everybody has heard of astronomy, and lots of people dream of being astronomers.
A friend of mine is working in paleogeology. As you might imagine there's not a huge amount of money in the field. On the other hand, few people have heard of it either, and there aren't that many people dreaming of working there. There's no movies starring daring paleogeogists with hat and bullwhip in hand ducking poison arrows and swinging across pits of snakes in order to determine the local sea bed temperature during the cambrian. The end result is that funding is pretty stable and dependable. People that are qualified and willing find funding. I bet there's a fair amount of other obscure fields in a similar situation.
You could write an open source application in C++ rather than the much less mainstream R language and you'd have lots of people ready skilled to maintain it.
You may be right in general. But R is not a general-purpose language. It's a programmable tool for statistical computing; you'd have to spend a lot of time to reimplement a set of high-quality statistical libraries to do the same. Doing that correctly is very non-trivial and not quick. Very similar to saying you can replace Matlab with your own C++ code.
One function of special vocabulary is for specialists to easily communicate. But another, important, social function is as a badge of in-group membership. If you use the words correctly (from the point of view of the group) you show that you belong, and that you probably know and understand all the other explicit and implicit rules of the group. If the word use spreads too far it loses this function and the group needs to find new words and expressions instead.
You dislike "gelling". You dislike "paradigm shifts". It would probably be a fairly risk-free bet on what you think of expressions like "optics" (as in "the optics of this decision is good") and the like. You dislike these words and refuse to use them. Which signals to management people that you are not management and should not be treated as part of their in-group. "gelling" works exactly as intended, in other words.
Asking for words to not be used like this is futile. It would be like asking people to no longer care about fashion (another in-group signal) or to not form groups of like-minded people at all.
Not many other countries intentionally bankrupt accident victims the way the US does.
I don't live in the US, and I agree. But, if you're found liable for an accident you will tend to pay a lot of money in any country; the accident victims likely have life or accident insurance and their insurance company will want to get reimbursed.
So good, comprehensive accident insurance is a very good idea no matter where you live. Usually we have that as part of our home insurance or other thing like that, and if you own a car you have mandatory insurance for that.
But in a case like this you may well be completely uncovered. The vehicle insurance is likely not valid for commercial traffic, and your home insurance may well not be valid either. As I said, I would never, ever get into a car like this without first being absolutely sure that the liability situation is crystal clear.
What they do need however is a license to operate a taxi, and that's determined locally, with a criminal background/medical/eyes check, and a very stringent but outdated local geography test that has been rendered completely useless by mobile applications such as Google Maps Navigation and Waze.
So require that the drivers have it, outdated or not. It's required by all commercial passenger traffic so it's not as f it discriminates against Uber after all. If they really don't like it, they're free to lobby and argue for a change to the relevant laws. Just arguing that "but we don't wanna follow the law!" gets tired really fast.
In the US, Uber covers you for up to one million dollars.
That's a pretty pathetic sum for traffic insurance. Remember, you may potentially be economically liable for several injured, permanently disabled or killed people, property damage and other costs. And again, as the one that commissions and pays for the trip, you just might find yourself shouldering part of the criminal liability too, if you didn't check that the guy you hired had a valid license for commercial traffic.
I don't know why Uber is complaining. All they need to do, after all, is to recruit drivers with a commercial license; require the vehicles to comply to commercial safety standards; and provide the needed insurance. It's not as if the deck is stacked against them - the other services they compete against all follow the same rules.
For my part as a potential user, liability is the real issue. I would never risk taking a car service where I'm not fully covered in the case of an accident. It's not just medical and other costs for myself; if the driver is not licensed you, as the one paying for the ride, may be regarded as co-responsible if your driver caused the accident in the first place. You want to risk hundreds of thousands of Euro in damages to save a few bucks on a taxi ride?
The basic complaint of the poster seems to be that in a store of hundreds upon hundreds of thousands of titles, only a very small number ever get discovered and successful. Huge numbers of very worthy apps never get a chance.
That problem can't be solved by any reasonable reorganization. We users (I use the Play store, but the same situation applies) have only so many minutes of time to spend looking for and using new stuff. However you make new apps visible to users, you're punishing apps that would have been visible otherwise. Competing for user attention time is a zero-sum game.
The Play store "people you know" ratings are surprisingly helpful. Unlike general user ratings this is not easy to game by the developers. But of course, those people may only have tested that one app because it was already more popular already.
I guess the only way to really fix it is to show each user only a random 0.1% subset of all apps. That would give every app a good chance of being seen and tried. But it would rather annoy all those people looking for irritated avians and not finding them.

At least they'll be neatly packed.

Could they handle that weight for such a distance, though? And in very rough weather, including rain and strong headwinds?
