Presumably you get your pop science entirely from tabloids dear anonymous coward because entanglement has been throroughly verified by experiment. Too bad Einstein didn't live to see the flaw in his EPR paradox explained (Bell inequality).
The size of the visible universe is only on the order of 10^9 light years, so that won't do it. But combine it with the range of the weak force, which has been measured and our direct measurement capability spans a range of about 10^39 (weak force ~= 10^-18 meters, lightyear ~= 10^12 meters, visible universe ~= 10^9 lightyears) so we can at least comprehend this number in a concrete way. Measuring it even indirectly... not going to happen with your basic bathroom scale. But we are talking about finding a way to relate effects on the Planck scale to the cosmogical scale so big exponents should be unsurprising. Unlike the outspoken AC above I will wait for peer review before adjusting my bullshit meter. Naturally, we all want to believe there is some big breakthrough here after the endless low calorie diet of contrived mathematical attempts to unify the big theories for the last too many decades. Is this one it? Seems unlikely just based on the long run of failed attempts. But I will just sit back with popcorn and enjoy the show. At worst, a refreshing break from the usual multidimensional mathematical salad parade. I'm particularly interested in more eplanation of how two entangled particles became one, at least according to the press.
It's bitter, isn't it? A bit too bitter for me, I generally go for 85%, but that is already up from 70% a year or two ago, which I now find too sweet. But interesting that the beneficial flavanols and flavonols are said to be bitter. Bitter = better?
Speaking of high percentage, there seems to be a high percentage of loose science in this bit of clickbait journalism. Failing to note that cocoa beans are roasted at relatively low temperatures and for a relatively short time, for one thing. And that heat may transform flavanols into other beneficial compounds for another. And that "dutching" to remove bitterness and make it easier to cook with destroys more nutritional value than heating or fermenting. And that even after processing, cocoa still has a high level of andioxidants because it started with a really high level. Really, this story left a (ahem) bad taste in my mouth. It has however increased my (ahem) appetite for something more intellectually nutritious on the subject.
I know it is unfashionable to RTFA, but if you do you will see that the story is about the non peer reviewed non research of a "cultural geographer" who did not have anything to say about the health effects of cocoa, but raised a question about whether one tribe being studied sourced its cocoa beans locally or not. Excuse me, but the headline made me think this was about the health effects of cocoa, not whether there is something magical about some particular strain of bean. Is there a story here? Is there even a researcher here?
Correct, developing glibc is the domain of specialists who devote years to gaining the necessary skills, not just any random walk-in-off-the-street general programmer. Try reading any part of libc and see if you can guess what your chance would be to get a patch accepted at your current skill level.
The corporate culture trickles down from the top. Tim Cook is a pencil pusher, not an engineer. Leading by example, every Apple employee becomes a paper pusher and engineering slows to a stop. Couple this with the normal work ethic degeneration in a large, financially comfortable organization and you have a perfect storm of attitude rot. Talented engineers get sick of it fast and leave for higher salaries or smaller organizations with higher career potential, leaving the beta facetimers behind to promulgate the usual organization idiocy. You see this at every big tech company: IBM, Intel, Cisco, Microsoft, Google, Samsung, it starts to seem like an inviolate principle of corporate evolution, like the death from inside out that always fells a mature forest, making way for the next crop. Apple just has this sickness worse than the rest because of the guy at the top.
Curiously, the Red hat dev did not comment on average case performance improvement, only on the slow path improvement. I initially missed that in a quick reading, as, I suspect, did many others.
Obnoxious GP happened to be right in this case, provided that the recursion is always applied to the smallest partition first, leaving the potentially much deeper recursion on the other partition for the tail, and provided that the compiler manages to detect the tail regression opportunity, which would need to be verified.
If you are unsure and have the time then write it both ways and compare them, no need to guess. If the assembly version wins then make it a compile option, keeping the C code for regression testing and to allow for compiler improvements over time.
It is to Apple's advantage to bloat up their OS upgrades beyond any reasonable technical need in order to force upgrades. A clear conflct with the customer, and since the customer has no real choice but to accept these OS upgrades, this practice seems sure to be on the wrong side of antitrust and/or consumer protection laws. However this is a self-remedying situation: by effectively making their products less useful and more expensive, Apple accelerates its market share erosion. In the not too distant future, only your mom will own an iphone.
Which Linux user actually got hacked by a library vulnerability this year? Speak up now. Oh, hmm, the sound of silence. Certainly not me, and not anyone I know of.
The thing is, sometimes the many eyes just aren't pointed in the right direction. A publicly disclosed vulnerability changes that instantly, hundreds or thousands of expert eyes to got work, fixes happen fast, and the community learns from the incident, often resulting in the eradication of a whole class of risks.
...as well as attacking all of our immune systems due to the ability to transport bacteria and virii all over the world at high speeds....
Thereby also transporting both resistance to those same bateria and effective community procedures, helping to improve world health in the long run. Note that the black plague propagated quite effectively around the world at walking speed.
Funny how things turn out, isn't it? Instead of having flying cars to make it easier for you to reach the world, we got the internet to make it easier for the world to come to you. No contest which strategy uses less energy.
It is particularly galling when a company that wants all businesses to pay to move into its cloud won't let its own employees work remote. (Starts with G)

Now I know that I am just entangled.
Massively entangled.

Indeed it was obvious. Your comments here are informative and would make a nice addition to the writeup.
...and that reply was meant for the GP
Where did you get the idea that vaccum is nothing? Actually, vacuum is a very busy place
You seem to argue for never doing any benchmarking of typical cases.
Curiously, the Red hat dev did not comment on average case performance improvement, only on the slow path improvement. I initially missed that in a quick reading, as, I suspect, did many others.
Obnoxious GP happened to be right in this case, provided that the recursion is always applied to the smallest partition first, leaving the potentially much deeper recursion on the other partition for the tail, and provided that the compiler manages to detect the tail regression opportunity, which would need to be verified.
On that note, I am pretty sure the optimizing was done in C in this case. The art is in the careful analysis of precision.
If you're doing it on your own time then muck around with anything you want. If you win you are a hero and if fail you got some experience.
If you are unsure and have the time then write it both ways and compare them, no need to guess. If the assembly version wins then make it a compile option, keeping the C code for regression testing and to allow for compiler improvements over time.
We weren't talking "general programming" here.

Google has investors, and eventually, this type of spending will be curtailed...
Not happening any time soon. The investors own non-voting stock.
