His data about electricity demand and production in Germany is wrong. To say the least. His assumptions are misleading.

He claims that Germany gets 5% of its electricity needs from renewable sources, when it is in fact 26% (I know he focuses on wind and solar, which is another problem I have with this text.)

The graph about electricity production from wind and solar and overall production is misleading. Because he writes about production but shows capacity. Which is very confusing. Also I'm not sure if he understood the statistics from the EEX. I'm not sure I understand them fully.

The comment about that you can't avoid fossil energy when you are connected to the grid is physically true of course. But it is the point for what you are paying. The grid is a lake of energy, and if I pay someone to put the amount of renewable electricity into this lake as I use, fossil energy is not put into this lake.

That is why a market for renewable energy works. There are few companies in German which sell renewable energy to end consumers. I get the same electricity as everyone around me but I pay for something else.

But I agree, those green energy certificates like RECS are utterly pointless. They do not helping.

Challenger was not the first explosion of a spacecraft in flight. Far from it. Apollo 13 taught NASA far more about safekeeping of radioisotope generators than any explosion on the way to orbit.
Sounds similar to Numenta's Grok SaaS offering machine learning and pattern recognition on streams of data[1]. Supposedly no ML experience really necessary for the customer providing the data streams.

It goes back to the mathematical roots of programming. Turns out that if your language consisted entirely of unnamed lambda functions, it would still be turing-complete because you could use one of several types of combinators to implement everything else. The Y combinator and a few other similar ones implement recursion, which is quite a feat for such a limited language.

Mathematical terminology exists only to add precision to human languages, which are notoriously vague. It can be overdone, of course. Polyvariadic is a bit silly, it just means that the combinator has been generalized so that it works on functions which have more than one argument (literally "many-variable-having"); the original Lambda Calculus pared away even that to leave just functions of one argument.

That hypothetical language, btw, is called the Lambda Calculus. It was formalized and studied by Alonzo Church, and entered software engineering most directly in the form of Lisp. Most of the research these days probably happens in Haskell and similar languages.
It is really nice to see good ideas percolate in from other places. I like the focus on making syntax cleaner and less boilerplate without being overly terse.
But you can use it to double your bandwidth (http://en.wikipedia.org/wiki/Superdense_coding) and "store" bandwidth (http://strilanc.com/quantum/2014/05/03/Storing-Bandwidth-wit...)

> Heroku is a great example of immutable servers in action: every change to your application requires a ‘git push’ to overwrite the existing version.

Um, not it's not.

Heroku's buildpacks code caches a hell of a lot of stuff on each execution agent. Still more code has to recognise and try to repair various broken states. It's mutability, through and through.
In my experience, the highest quality code is often written by the fastest developers. Among their skills, I notice a few things: 1) Discipline with syntax. 2) Precise and accurate naming for variables, methods, etc. NPR recently ran a story on the phrase "mise en place" that resonated with me about syntax. I often see sloppy syntax and bad naming slow down developers. They repeatedly trip over their own code. 3) Strong data manipulation and transformation skills. Fast developers usually have a deep understanding of the data structure they're working with and how to best manipulate it for the desired outcome.
Sadly, it's not rhetoric.

Also sadly, yes you would think some progress would have started years ago.
Yep. It's "effective" in that it's not suicide.
I'd love to know why, but the article doesn't load with NoScript.
For consumers the device is not ready but I would wager that a fair amount of value could be gained from using it in an enterprise context. All sorts of jobs get easier if you have access to data hands free - surgeons being the most obvious case.
From my understanding, it cannot be used to transmit information because the measured property of the entangled photon or particle is not chosen by the the experiment. It is truly random.

It could be used to ensure that 2 locations have the same random data. This is useful in cryptography.
I'm so tired I'm not even sure why I'm posting. I have
spent so many days thinking about the treatment of
psychiatric disorders; it literally gives me a headache.
I agree that Psychiatry is still in the Dark Ages(not figuratively, but in some ways so close to the right period
in time it's humorous.) I won't state what I was diagnosed with, but what I will disclose is it came on one Christmas
Eve and went on for Years. I tried all the tri, and heterocyclic drugs. They all failed spectacularly. The
only reprieve I have gotten over the years are highly addictive drugs. I now just try to keep the dosage low because I know if my current doctor retires; I'll have a
hard time getting these drugs, or run out of money paying out of pocket for unnesarry office visits. I don't blame
the Psychiatrists--that is the Psychiatrists who don't call
themselfs "Specialist in Psychotropic Drugs", or a dude who
charged $400.00/hr for dubious advice and medication. Who
I do blame are the Drug companies and their oh so carefully
designed Double Blind Placebo Controlled studies. Studies
which were pimped out to the cheapest Ho(country). Studies
that were cherry picked in order to show the FDA their dubious drug worked slightly over Placebo. Studies that didn't exclude early Placebo responders. Studies that didn't account for subjects who felt the side effects and attributed to the Placebo Cure. And--my last gripe; Studies
that didn't really use subjects who were clinically ill.
Yes--they were poor, and many times Homeless, but they really didn't have a malfunction in their brain.(Yes--they
might have had symptoms out of DSM-5, but because of their
predicament many of their symptoms could be accounted for.)
While I'm on the soap box, I'll pass this along. I'm not
sure this s the truth, but it came from a good source. It
is this; I was told that Fluoxetine(Prosac) showed so little promise it was "shelved" for years until some MBA
in Business decided to he could market a cureall drug--that
is if the researchers played along?

This is stupid. His shirt looks like old pinball artwork. It's obviously a vintage throwback that's harmless to anyone who isn't currently obsessed with gender politics.

These feminists are so divorced from reality they are desperate and seeing everything through the prism of their bunk thought-experiments that they have to make literally everything about their imaginary oppression.

Can we have one good news story without trying to make it relevant to your gender-studies major?
For some reason, articles on time.com don't scroll…
The difference is that when you separate a quantum Oreo, until you actually observe which side has the creme on it, the universe hasn't decided yet. Once you observe one half, the universe instantaneously picks one of the two halves at random to contain creme, and one to be empty.

We know it must be this way due to statistics. However, that's the point where the Oreo analogy breaks down.
> You have me truly puzzled over whether you are feigning incomprehension over this or you honestly don't get what the ordinary joe six-pack or the average hockey mom makes of a future filled with dehumanizing conditions for mankind when coupled with the film's vivid representation of replicants [1] not to mention the deluge of postindustrial decay in its imagery.

The point that you are making will always seem clear as day to you because you are the one that believes it. The onus is on you to make sure that the rest of the world can understand it if you want to effectively communicate with others. If you have multiple people saying that they don't understand you, throwing up your hands in the air and saying, "Y'all must be trollin'" isn't very useful.

That said, we don't need to delve into fictional cyberpunk dystopias to find examples of "science run amok," so I'm not really understanding how getting movie critics to write editorials criticizing movies that show us bleak futures is all that useful, or necessary.
oh wow.. i'd love to see an addition to this for tessera.
Here's the first essay I remember on the subject: http://www.joelonsoftware.com/items/2003/10/13.html
Yes I am a Chinese.

The "one POV" thing is not about how interconnected the world is; it's about language barrier. An English site will always be dominated by people whose native language is English.
All components of a quantum system are always entangled. It's not some mysterious property that arises under unusual circumstances. In fact, I would argue that quantum entanglement is the defining feature of quantum mechanics that distinguishes it from classical mechanics.

However, the way that most articles (and even physicists) use the term "entanglement" is in a loose way. Within a good approximation, a multi-component quantum state can be represented as a tensor product of single component quantum states. When this isn't a good approximation anymore, you can say that the entanglement of the system is much more apparent.

To give an example of what I mean, there's a technique in quantum chemistry known as density functional theory (DFT), which is used to compute ground state energies of various molecules. For some molecules, it works pretty well. The benefit of DFT is that it is a fast calculation technique (well, as far as quantum chemistry goes), but it's speed comes at a price. Rather than using the Coulombic interaction of every pair of electrons to compute the energy of a molecule (or more technically, using every Coulombic interaction as terms in the Hamiltonian), a probability cloud of electron positions is computed instead, and this cloud is used as the energetic term.

This works really well for a lot of systems, but in some cases (superconductors, metals, solid-state physics, van der Waals interactions), this approximation falls apart because the effect of electron-electron correlation significantly affects the energy of the system. In this case, the full, non-separable wavefunction is required. The fact that this full wavefunction cannot easily be broken into an approximation of simpler, single electron wavefunctions means that the entanglement of the system is very apparent.
I (and others apparently) down-voted this for the tone. Your last paragraph wasn't necessary and detracted from your overall point.
At least you identify the issues and many are in denial mode throughout their life.Don't hard on you, once you find your passion you will be very successful. Just keep looking your passion.
I strongly agree. What would help most JS programmers (especially in node) would be to leverage the great asynchronous features in JavaScript and eliminate the nested function pyramid of doom. Callbacks and nested functions work great until you have conditionals or want to use try/catch blocks in a reasonable way. Promises are a viable solution but I've never really been a fan (it just feels weird).

This was the rationale behind Kal (https://github.com/rzimmerman/kal/), which effectively provides "await" (called "wait for") in ES5.
All human languages consist of syntax and phonetics. Programming languages act as an intermediary between human intelligence and machine intelligence. We almost always require the language aspect of programming to communicate with computer hardware. It is a link for compiling syntax between both the human mind and the computer mind. We need a common means to compile information, just like communicating ideas between people. Programming languages are exactly the same thing as traditional spoken language.

I'll argue that to parse any language requires a specific cognitive skill. Ever sentence diagram, look up a word in the dictionary, or look up what specific programming "words" do in a computer?
It used to be possible to pair Glass with a bluetooth keyboard, and there are some very nice keyboards on the market which fold up to about the size of a cell phone, and unfold to about the size of a normal laptop keyboard. This is as good as a laptop keyboard if you put it on a table, pretty good if you rest it on your lap, and passable walking around if you hold your thumbs on the bottom to stabilize it while typing with the other eight fingers. The main caveats are that the Glass screen isn't very high resolution, so you can't get much more than 80x25, and it's not very usable while walking around even if you can manage to type, because head-vibration makes small text unreadable.

Unfortunately, this is impossible in versions of Glass since XE16 (April), and fraught with difficulty in the version before that (XE12, where dialog boxes don't work, so you need a modified SSH client and a modified Settings app to pair). I also had to modify the ssh client to fix some keybindings, and to add a left-margin because my device was missing 4 columns of pixels on the left edge. When it works, it's significantly better than ssh on a phone, because you can use a real keyboard without needing three hands or a surface to put things on. It's less nice than a computer, mainly because of the low screen resolution.

I think we should think outside of the (human) box. We needed emotion, I don't think machines do. Well, the machines we will build will have emotions as we cannot socialize with them otherwise, but a problem-solving AI does not need any of that.

The issue is an always-on-esque digital camera permits you to make a permanent record with limitless distribution anything you saw with your eyes in a way that isn't potentially falliable like an anecdote is, and you can share it with everyone and anyone at any time.

Most people out in public do not want this to be the case at your personal discretion.
J.S. Bell addresses this in the paper https://cds.cern.ch/record/142461/files/198009299.pdf with the following example: "Dr. Bertlmann likes to wear two socks of different colours. What colour he will have on a given foot on a given day is quite unpredictable. But when you see that the first sock is pink you can already be sure that the second sock will not be pink... " But it turns out that the quantum situation is much spookier.

If you are interested in a printed version of a great beginner's compiler book, I can highly recommend Andrew W. Appel's "Modern Compiler in C". There are also versions of the book written for SML or Java. I have read and partially implemented the C version and I really enjoyed the book, basic enough to follow yet full-featured enough to be useful.

The book starts with parsing (I prefer PEG or Pratt parsers for their simplicity (and tool independence) to be honest and skipped some of that chapter) but then goes into semantic analysis, type checking, code generation, optimization passes, even mentions basic type inference.

There is some code online at http://www.cs.princeton.edu/~appel/modern/c/ .
I see nothing counter-intuitive about quantum entanglement. Photons travel at the speed of light--time does not exist for them. Alter one, the entangled one is instantaneously connected.

“JPL is the cornerstone of Caltech’s financial security,” Stormer said. “It makes them one of the foremost research institutions in the world. Without it, Caltech is just a backwater institution with very bright people. They could not get the people here that they have without the access to the research facilities at JPL. It is what makes Caltech Caltech.”

I don't know about the merits of the case, but this kind of wild statement is embarrassing. JPL is lucky to have Caltech close at hand, not the other way around.

@FrancescoTop is my boss! :) Lots of ups and downs over the last couple of days, but I think we can say that Philae is an unmitigated success. There's a lot been said about the problems faced, but despite that, there's been some great science data downlinked and hopefully a lot of fantastic discoveries ahead. Philae has helped shed light on a lot of outstanding issues in Solar System formation and planetary science. The hope is that this will help spur on further research and lead to more insights into the ingredients that go into the models that describe where we came from and where we're going.
Regulation before, the whole monopoly thing, came with rates set based on a rate of return, in exchange, all traffic had to be carried equally - and service had to be provided universally, meaning to every customer in the service footprint.

If we return to that mechanism, it will all work, if we try to do one or the other, nothing will work, meaning, you can't net neutrality it without making internet access a common carrier product, and by setting rates based on a reasonable rate of return.

Local regulation is a far bigger impact on building out a new network than any other single factor - it can take up to two years just to pull a permit to upgrade a cell site cabinet, its an order of magnitude more for something the magnitude of building out even a FTTN network.
For mine, scientific endeavors such as these are worth much more than the experiments they entail; they help inspire the next generation of scientists, engineers, mathematicians and so on.

Exactly what the American people have come to expect from the government. Unless its been gift wrapped by a contractor they lack any ability to do anything technical.

You make a RPM and you deploy it like you would any other package. Yes it is a best practice, in fact the people at Red Hat do the _exact_ same thing, the difference is they have the technical capability to make those kinds of changes, as do most people in the commercial IT sector. The government is the one place where they call it IT when its really just glorified procurement.

However thats not even the problem as you stated its supported just fine. It has been for almost 9 years. The bigger issue is there was a perception is wasn't and instead of working to see what reality was people just did nothing.

Good opportunity to again promote »The Theoretical Minimum« [1] by Leonard Susskind (born June 1940, director of the Stanford Institute for Theoretical Physics with research interests in string theory, quantum field theory, quantum statistical mechanics and quantum cosmology). It is pretty accessible and a key takeaway is that there is a lot of misinformation in the wild and especially on the internet when it comes to (modern) physics as he tell his class not only once when someone asks about something he read somewhere.

How difficult is it to build an ISP? I feel like net neutrality would prevail if the market was opened up, even without government help (but certainly not a market in which 95% of America has less than two choices for internet provider). Is the problem that cities have already sold their souls to get the internet deals they have?

Broadcasting internet over the air seems like a much easier way of entering new markets than laying cable: where are the 4G home internet providers?

I realize Google Fiber is likely just an elaborate negotiation tactic to scare AT&T et. al. into not being shitheads, but Fiber spreading everywhere would be good for everyone.
