Working towards social equality causes starvation because Stalin and Mao (and probably Pol Pot)?
Yes, when you aim for too much social equality, the end result is what Stalin, Mao, and Pol Pot did.
Social equality should mean equality of opportunities, not necessarily equality of results. For instance, everyone should have access to an education, but if your ghetto culture makes your school a gang war zone, that's not a problem caused by the elite.
The problems caused by Stalin, Mao, and Pol Pot came from them trying to exterminate the people who had better living standards than others because they were more honest and worked harder.
Clicking one of these links, stepping through that sub-process, then hitting the 'return to last position' shortcut is far faster than flicking through a printed manual.
How is clicking a menu to add a bookmark easier or faster than inserting anything that's at hand in the page?
If I want a more permanent bookmark there are a variety of stickers that I can use, using different colors or making annotations if necessary.
When I'm holding a book and need to follow two different parts at once, the best procedure is often to hold a finger in each page and alternate between them by twisting my wrist, how could any clicking be faster than that?
I need to move the mouse to a precise position, aim the pointer and click. In a tablet or similar it's even worse. I usually need to use both hands, sometimes magnifying the screen to be able to tap the exact position.
Replace "structure" with "object" and you'll see why most programmers think in terms of arrays of structures and not structures of arrays.
Anyhow, for me that shows an intrinsic limitation of object oriented languages and why C still rules strong. When you run into the limitations of the hardware, you get to a point where object oriented languages are a limiting factor in optimization.
When I started learning how to program neural networks in the 1980s, I realized that by turning object oriented programs inside out one could get orders of magnitude better performance. That's where the power of C with its flexibility in handling pointers come into play.
Instead of declaring neurons as objects containing inputs, weights, and activation values, I declared arrays of weights, inputs, and activations. That way, calculating the activation of a neuron became a dot product of an array of inputs with an array of weights. The dot product is a common operation that is well optimized in any CPU.
The concert was completely ruined for the orchestra and the entire audience -- the profound effect of the music was lost.
That guy should face civil and criminal responsibility for his acts. You can't just go and ruin a concert that cost thousands of dollars to enact.
Considering that people had been preparing and expecting that experience for a long time, it wouldn't be too much to make him pay, let's say, $5,000 to each person in the audience plus $100,000 to the production.

When all your in-house innovation leads to outhouse fabrication
How much innovation is needed to fabricate a tiny room?
Buy everyone who innovates and shut out any possible competition
In this case, I believe you mean shit out any possible competition.
So nothing is stopping you, except billions of dollars of capital you don't have.
And this is where the idea of intellectual property makes sense. If someone invested billions in creating something, he's entitled to profit from that.
It's not like those billions were lying around. People worked to save money and invested it in shares of those companies, that's where the billions came from.
For (a trivial) example, suppose I specify that I want a program which takes two numbers, adds them and outputs the result.
If you think that example is trivial, it's obvious you've never heard of Giuseppe Peano.
For acceptance, that program should be tested to see if it implements a correct mathematical induction algorithm for addition.
with the specifications I write there is no excuse for not testing their code.
In every engineering project I've ever worked on, the specifications included acceptance tests. Obviously, his specifications aren't good enough.
He should detail with his customers the functional specifications of the product and generate a set of acceptance tests. The end product of this would be a test procedure, which both the customer and the contractors have previously agreed upon.
There is no excuse for a contractor to blame the programmers who did not conduct testing, if the way the testing should be done has not been previously detailed. The formal test procedure is what separated bugs from features.

Which nation does the "National" in NRA mean?
The reason why they recommend lower and lower alcohol contents has more to do with the way they collect statistics than with any real effect.
If any of the drivers involved in an accident has any alcohol blood content at all, it is recorded as an "alcohol related accident", NO MATTER WHO CAUSED THE ACCIDENT.
This is bias in the worst sense of the word, it's political propaganda at its worst.
Suppose you drank one beer and is stopped at a red light. Then a madd bitch rear ends you. It will be an "alcohol related" accident, pointing to the "need for stricter drunken driving laws", even though the madd bitch caused it.
The top systems today are approximately at the same capacity as a human brain.
Brain neurons perform an operation that's similar to a dot product. Their operation can be simulated by a weight for each dendrite that's multiplied by that dendrite's input.
In rough order of magnitude, a human brain has a hundred billion neurons, or 1e11 in standard computer language notation. Each neuron has an average of one thousand inputs, 1e3, and performs a hundred operations per second. That is 1e11 * 1e3 * 1e2 = 1e16 flops, or 10,000 teraflops.
According to Top500, the highest powered computer system in November 2012 had a capacity of 17,590 teraflops.
This doesn't mean it has the same ability as a human brain, because there's also the software involved. There is a project, sponsored by Google, that tries to implement a computer system operating close to what the human brain does.
When they tested that system presenting to it one million random screenshots from Youtube videos, the system learned all by itself to recognize objects that appeared on those videos, like human faces and cats.
There's a good technical tutorial on this system at the Stanford university site, and a more basic explanation can be found in several popular articles if you google for "deep learning".
TFA says the waste has settled into layers, solids at the bottom, and the system they have will mix it all and pump out the sludge.
Wouldn't it be smarter to pump the liquids out first, and worry about the solid part later? They say the most urgent problem is that some tanks are leaking, and solids don't leak.
The "rape" he is being accused of is a radical feminist definition. He is a male being prosecuted by a society where males are subject to discrimination. Not fair.
He is in a similar situation to a black man accused of rape in Alabama during the 1920s.
