Who should tinker with toys if not children? Or just because something is fun it can't be educational? The best use of 3D printers is education: they teach the basics of design and programming, and are very good at printing short-lived plastic toys.
Theoretically they can. The Bitcoin network keeps the history of transactions. But to check that they needed to seize the coins. It's not just money, it's evidence.
Actually, it's very interesting. It shows that even with the very extensive testing and layers of planning and managerial processes to prevent such errors, they can still creep in. And it shows that very expensive, one-off projects remain vulnerable to subtle design errors, so the tools to do field updates are _critical_.
That's true, but has been known for a while.
Note that designing for spacecraft can be a real artform: they have extremely limited computational resources, due to the inherent risks of bit errors in increasingly small modern silicon exposed to radiation and temperature changes, and you cannot simply shield the electronics: the shielding adds weight and itself becomes radioactive over time. So you often wind up using quite old but far more stable technologies. That means tools that may be considered quite obsolete by the time your design phase is complete and the device is ready for launch. And by the time it arrives _on Mars_, the techonology is very obsolete indeed.
That is indeed an interesting topic, and I wouldn't have complained if the article talked about that. But it was just a generic description of a common error with almost no details about the actual system. I didn't say that I don't respect the engineers working on the project. Even the best minds make simple errors. It just doesn't make for a good story.
Seriously? This reads like morality tale for beginner programmers. "Remember kids, always check the settings of your mutexes!" Will we also have articles about NASA engineers mistyping == for = ? Everyone makes mistakes, just because it happened in a rover doesn't make it interesting.
Because the US is the master of divide and conquer diplomacy. I wonder what the eurosceptics have to say about this, the individual European nations don't look very free and independent now sucking on America's cock.
On the contrary. 30 years ago people were using silicon based panels that were cheap to produce. Modern panels are mostly rare-earth based, and their production causes massive pollution (and I'm talking about actual pollution not CO2). I'm not sure where you get your numbers, but putting a single breakeven duration on solar panels is ridiculous. The energy production of a solar panel is influenced by many factors like geographical location, weather or alignment. That said, panels are not the only form of solar power.
Connection of a spinal cord from the head of one creature to the body of another has never been attempted even in animals, so Canavero’s paper must be taken as an exercise in speculation.
It's not the flow of heat that can be seen, only heat radiation. Which is not the only way to transfer heat. There's a huge difference between directly imaging a 36C hot body or only seeing the surrounding air being a couple degrees warmer. That's much harder to catch.
Cooling is the removal of heat.
Care to back your argument with more than tautologies?
It may be possible to create a fabric that doesn't let thermal radiation escape, but lets the air through so convection can cool the wearer. That would actually be worthy of an article.
I guess it's an age thing. Kids would prefer to live on a farm. Adolescents and young people like the big cities. When they grow older and have children they move out to the suburbs.
Mathematicians don't bother with such low-level expressions. This is indeed a problem for engineers. A good engineer would know how to load the problem into Matlab (or whatever symbolic solver engineers use), and lean back while it computes the answer.
Only buy a finished product unless you have money to burn.

Well, it's still nice that you bothered to sign up so you could tell this to us.

Not really, most bugs are easy to fix once found. Especially trivial ones like this.

There are many different protester groups and not all of them like the military.
You can order food on the Internet.
Missing from Amazon and unavailable are two very different things.
Concealed guns aren't a new idea.

The point of TFA is that it only appears to be more efficient when production costs aren't taken into account.

Yes, it is. From TFA:
Mind you that the tested browser was a Firefox without any addons, which is why it appeared so fast.

Yeah, it's sad watching him giving his name and reputation to games not deserving it.
We made our bureaucracy so vast it's impossible on spy on all of it.

I guess it depends on your definition of solution. If it contained an integral that can't be expressed in a closed form, I would call that unsolvable.
It was solvable, just the solution wasn't the intended phone number.
