Start by adjusting your estimates. If you assume just neurons and synapses, you're on the petaflop scale. The two first entries on the TOP500 list barely get there. (92 & 38 petaflops, brain assumed at ~30)

Supercomputing instances built w/ EC2 are in the 0.25Petaflop range. Assuming that's only a fraction of their machines, maybe the major cloud providers play on the same scale - and at this point, you have to deal with communication across DCs, which might make realtime simulation utterly infeasible. That's 2 yes, and 3-5 maybes, not "over 1000 organizations".

Then you're looking at the fact that recent research indicates dendrites carry processing power as well, which would move any brain simulation well into the exascale range. And Moore's law is shakey by now.

But given all that is overcome - we seem to be doing OK at the scaling up thing - you would need a complete connectome of the brain. So far, we've succeeded doing that for roundworms. (And 6502's, as the article shows :)

The human brain is a far cry off from that.

But let's be optimists, and stipulate that is at some point done as well. We're still in the dark, because we have no idea if a fully connected brain will work without being in a specific starting state. We're nowhere even close to map the state of a brain. And at this point, we're definitely in the realm of questions where we don't even know yet if we will find an answer at all.

Want more curveballs? There's a non-zero probability that the brain can only be fully explained using QM explanations. You've just significantly shifted the scale of the simulation.

I don't know NEVER is an appropriate word, but it's not totally obvious, either. Using the word "obvious" in this context (just like the word "never") means you've reduced the problem to pop-science, where everything is either black or white.
Every time I try to get into org-mode, I just don't get where to start and how to do things. So I end up going back to Sublime text, creating markdown files to take my notes, works well.

This gave me an idea on how to organize interesting stuffs and it's quite simple. Thanks! I hope nickpeterson did got that idea too. And what I could recommend is to use emacs and org-mode everyday especially when taking notes. You can't learn without using them. It gave me lots of benefits.
It is a very well known project, I didn't feel the need to introduce it.

You can see some demos here:

It's free/open source and can embed lots of different technologies:

I think Jupyter is very powerful, the learning curve is lower, and you can share your documents in an easy way if you need to.
Ask HN: Reposting dilemma in Hacker News
What if my post does not get any attention at all, can I repost it? Rule says-

"If a story has had significant attention in the last year or so, we kill reposts as duplicates. If not, a small number of reposts is ok.
Please don't delete and repost the same story, though. Accounts that do that eventually lose submission privileges."

The guideline is from story/news repetition perspective but it says nothing about the person who posts. So I'm not clear if I can repost my own post.
Coming to the reason from where I got this requirement (pretty serious for me), We recently revamp our product site, I'm sure it's better than it's ancestor but skeptical if it meets standard UI/UX guidelines. Our sales figure, after launching the new site, does not see significant change either, which further provoked me to get some suggestions from other people. Yesterday I post a "Show HN:" requesting our community to provide their valuable feedback. Honestly speaking, I was expecting at least 5-6 suggestions but to my surprise, none came. It got only one comment and no evaluation. I know almost 90% of stories does not get engagement at all due to various reasons. But for us, it's not just a story, our survival depends on this product. So am I allowed to repost it again? If so, is there any mandatory time gap?
N.B. - I intentionally exclude the post link as that might be seen as promotion as well.
Ahh, I already updated my answer to cover some of your point, however you have thought of far more words in English than I did :)

No!!! There is absolutely, 100% no roadmap for interplanetary space travel, certainly outside the solar system. (Within the solar system is arguable): the 7 planets just discovered are a good example, I love this comment on HN: https://news.ycombinator.com/item?id=13707775

"If you had a near perfect hydrogen -> helium fusion engine, it'd take about 6 million tons of fuel (about the mass of the Pyramids of Egypt or 2,000 Saturn V rockets)".

Does this sound like a roadmap? "If you had a near perfect hydrogen-> helium fusion engine"... "mass of the Pyramids of Egypt"?

Contrast this with the hardware I'm talking about: by my estimation there are 1,000 clusters today, today, that can run the appropriate software if we had it. The idea that someone would call it "impossible" at a time when conventional human thinking challenges such as playing Go, are being mastered by machine using machine learning, seems crazy.

I absolutely do not agree with you that we have any roadmap for interplanetary, certainly extrasolar, travel.

Contrast this with the Human brain. We can count the neurons (100 billion or so). It uses as much energy as a 20 watt lightbulb[1] but doesn't have light-speed interconnects, unlike server rooms. The roadmap we are following, simulating neural nets on bigger and bigger hardware, is pretty much the exact thing you'd expect us to be doing. It's yielding amazing results in machine learning.

Why would anyone think that the biological, slow-firing chemical analog process these huge, super-fast digital processes replicate, will be out of reach literally "forever".

It is literally possible that not one human being will ever travel outside the solar system - not in the next 1,000 years; 5,000 years; or ever.

The idea that we will "never" simulate a hundred billion analog neurons running at 20 watts seems childishly naive. It seems like saying "no machine will ever fly - period" when machines are already doing more than enough work to do so. Come on.

Anyway I am really interested in stochastician's answer here - this is why I wrote them after they offered to answer any questions ("appy to answer questions.").

I've handled the hiring of almost all Web developers within my company for the last half decade, and in that time I have hired absolutely zero women. Yet, this has nothing to do with discrimination and much more to do with the applicants themselves and the numbers by which they apply.

During this time, I've seen Web design positions attract females applicants by about a two-thirds majority, whereas Web development positions attract only one in twenty (if that). And yet, those who have applied seem to fit into two distinct categories of undesirables:

First, the designer, with a design degree, who learned to code from some two-week academy that now feels the need to apply for a position well beyond their skill level. Or second, the mathematics major (or similar) who feels their knowledge of topics only related to programming in general is satisfactory enough to hit the ground running as a Web developer of all things...

So I'll be happy to discuss the potential of a wage gap if I ever seem to hire a true female Web developer.
And what about macOS and Airports?
What makes you think that it would take 300 years, given that humans are being beaten at extremely creative computational tasks like playing Go, already?

This should have been a series of posts, compiled into a guide. It should be easy to cut this up into digestible pieces, but it's sort of a massive throw up right now.

(edit) Ah - now i see- it is a guide. But it's a single page layout, with navigation on the right. So I guess it just violated a few of my assumptions. I think I also assumed it was a blog post since the h1 title doesn't call it a guide (though the html title does).

You meant it as a funny statement, but it is actually true. Here in Bavaria, we actually have too many wild boars in the forests, but hunting them for meat is limited by the fact that they are still partially contaminated by the radiation left from the Chernobyl disaster. So about 1 out of 3 animals shot have to be destroyed.

If you want help the people who do not own or do not want to own a home - and I agree that we should because i'm one of them, the government can:

* Build more homes (using compulsory purchase where necessary)

* Raise council tax and make the owner pay for it (not the occupier) and use the proceeds to build more homes.

* Eliminate mortgage interest tax deducations

* Raise interest rates

* Don't privatize the land registry like the Tories are trying to do.

Eliminating tax deductions on solar panels will mainly just help the oil, coal and gas oligarchs trying to set us at each other's throats.

Time doesn't exist. It is simply an abstraction to measure the comparative rates of the movement of matter.

All our measurements of time refer to the movement of matter: the rotation of the Earth, the orbit of Earth around the Sun, the swinging of a pendulum, the vibrations of a cesium atom.

Time travel is not possible. It would require the re-arrangements of atoms into exactly their former position, which is precluded by entropy. Too bad.

There is no past or future. There is only the forever "now".

Start using the tools.

For LaTeX: I very strongly recommend picking up a copy of the Lion Book (Leslie Lamport) and running through the examples. I actually picked up a great deal by taking documents I'd found online in bastardised for and tagging them up manually in LaTeX for output into flexible formats -- HTML, PDF, ePub, and more. It turns out that the basics of LaTeX are, well, pretty basics. Paragraphs are double returns, which buys you a lot. Italic and bold text, and the ``quoting'' style, are the main adaptations I had to make.

Digging into the equations and images features takes some doing, but you can produce excellent docs well before that point.

Stack Exchange has a wonderful LaTeX community.

Of the rest of your list:

1. Emacs: I actually got pretty good at it at one point, then signed on to a gig (in the days just before running one's own Unix was readily possible) in which it wasn't available and the boss (idiot) didn't believe in installing anything which wasn't vendor-provisioned. That said: commit to using it. I've found that I prefer vim's editing modes, but there's viper-mode in emacs. The power of having all text interactions under your editor is ... immense.

2. Regex: Start with the basics. The Sed & Awk book (O'Reilly) is a good start. Most of it is simple substiutions, and you can get tremendous mileage from that, though as with many tools, you can abuse the concept. Perl remains probably the canonical home for advanced regex use, though most languages have some facility for it now.

3. Bash: I'd recommend this, if only because Microsoft has a poor track record of integrating with others and/or supporting other tools over a long period of time. Bash has existed on Windows since the 1990s under various toolkits, most notably Cygwin, and is now pretty much native.

4. Unicode: mostly a matter of figuring out what bits you need within a given project. I'd deprecate that on your list and consider it something to pursue on an as-needed basis.

I can't much speak to the remainder of your list, though I'd suggest treating them as tools adapted to uses and goals.

That's new to me, but yeah, when I hear the term it is used to describe properties that are not discretely measurable and to me those might as well just not exist, or wrong as far as that relates to the grand parent post.

You are conflating impact and controllable individual risk.

If there was no exclusion zone at all the impact from fear would likely still be larger. That measurement wouldn't help the people getting large radiation exposures inside the zone.
Fiber has two effects: it slows the rate of digestion, and it provides energy for gut bacteria that can metabolize it. The objection to blending is that it loses the first benefit, but this quote talks only about the second.
There is a difference between "there is no risk", which I did not write but you imply I did, and "this risk is greater than this other risk", which is what I did write.

See the WHO evaluation of the the Chernobyl disaster, which states that the largest public health problem of the disaster has been the mental health impact (link in other response: https://news.ycombinator.com/item?id=13829192).

Again, that doesn't mean that there weren't other impacts, but the mental health impact was larger. I also remember seeing video footage of all the animals that died after Fukushima. They didn't die of radiation, they died of neglect.

Also, the health impact of fairly low radiation dosages is effectively unknown to date, but data from the Chernobyl incident keeps correcting the effect downward every 10 years.

The idea that "there is no safe dosage" was created artificially, because after Hiroshima and Nagasaki the exposure effects were simply linearly extrapolated to zero. There was no actual data there.
You should reach out to the researchers mentioned in the article and tell them they are wasting their time.

Crystallization of time seems like a misnomer to me. Aren't they continually adding laser energy to the system to maintain the "crystal" state? Doesn't crystallization imply a stable state resistant to external energy sources rather than dependent on them?
It really is interesting that only in the last 20-25 years has the obesity rate really taken off. In other words, it doesn't seem like this was gradual linear trend starting much earlier.

Or did a single major change occur in the 90s, such as the food industry introducing a key st of addictive ingredients?

I am not a MD, but I think it is accepted knowledge that elevated radiation levels shorten the life expectancy. How much, depends on many factors, like the exact nature of the radiation, like you are exposed to it, or have a likelyhood of eating contaminated foo, and of course your very age. The older you are, the less likely you are to suffer from this.

I haven't done research on this myself, but I would assume that the exclusion zones have been set up according to the accepted standards for radiation safety levels.
