It doesn't drop vertically back down the elevator cable! It performs a Hohmann transfer from GSO to LEO.

The delta-v to transfer from GSO to an LEO at 400km is 4km/s, whilst to go from ground level is about 7km/s.

That's a significant fuel reduction, _and_ that fuel doesn't have to go up all at once: you can keep fuel tankers at the GSO station and fuel up a rocket from there.

How does this contradict your earlier comment? I think it's still valid: Person A believes H1 (real psychic), Person B believes H2 (talented fraud). The question now is how to get them to agree. And the answer is: design a better experiment, such that fraud is not practical, and see what happens.
In this case, it seems so. However, I must say I've reported many vulnerabilities to Google since and they've all been handled within that time-frame.
Well, speaking as someone who has actually enforced the Clean Water Act while in service to the public as an officer in the Coast Guard, and having traveled the globe with an eye for maritime commerce and water quality as a whitewater enthusiast, I can say that the United States does a good job compared to most of the rest of the world.

'Shared infrastructure in the hands of the public' means government or regulated monopoly.

The local government, with greater pressure from local industry failed in this case, which in my reading, is an argument for greater federal control.

What other way to implement the granting of a special privilege, oversight and judgment, is there for something like water quality? Yelp?

Yes, writing a book requires serious organizational skills. But no diff or sync algorithm is going to handle this so I don't know why you're bringing it up. When it matters (and for many docs it doesn't), it's up to the users to coordinate on their work.

Even with programming, we don't use source control systems to find conflicts between distant parts of a program. We see if it compiles and all tests pass.

This isn't correct. Air resistance increases at the rate of velocity squared. At the speed those rockets achieve, is is a big factor. Elon Musk himself likened the atmosphere to a "thick soup" when it comes to launching rockets to space.
Not being snarky but it would be nice to have a drug that cures the sort of fear associated with FUD.
I feared that many participants here would react to this interesting article's headline rather than to its content, and it appears that that fear is warranted. But, seriously, this is a thoughtful article and well worth reading for better understanding of debilitating phobias and how they are currently treated. It is also good to read the whole fine article to see what the medical doctor author has to say about the trade-offs of the proposed drug treatment suggested as an addition to the currently standard exposure therapy. I don't know anyone among my close friends who has a phobia as disabling as those described in the article. There is a big difference between such phobias and the everyday caution and avoidance of rash behavior that helps keep us all safe.

AFTER EDIT, AFTER OTHER COMMENTS TO THE THREAD: I remember that back in the 1980s propranolol (a beta-blocker originally prescribed to prevent heart disease) was investigated for anxiety conditions like stage fright. (The cases of stage fright among performers I know best largely resolved as the performers gain in performance competence from more coaching and practice and reduced fear of performing by performing in public more often.) So this line of research about propranolol has been going on for a long time.
I think this is the best summary of the situation I've found

1) Flint’s elected leadership makes what is actually a solid, sound decision that will, in the long run, save the city millions of dollars and give it more control over its destiny – and, because it positions Flint as a wholesale supplier of water, possibly enhance revenues for them.

2) Detroit Water Board decides to be spoiled and pissy and leaves Flint with no good options for the two years before its pipeline is built.

3) Flint’s leadership and GOP-appointed EFM make a well-deliberated decision to draw water from the Flint River.

4) Flint’s water staff – the people in Flint who are the experts on this sort of thing – apparently aren’t up to the task. And the people they count on to oversee and help them …

5) The Michigan DEQ, is completely asleep at the switch. And once they discover their mistake, they lie about it and ask Flint to help them lie.

6) US EPA is aware of a problem, but apparently trusted the kids playing in the DEQ sandbox to fix things.

http://gregbranchwords.com/2016/01/17/the-real-tragedy-in-fl...

Most of the steps are understandable mistakes but Detroit's water board acted badly and I think some people in the Michigan DEQ need to face prosecution.
As a C# developer I rarely write unit tests, because of static types and compilation identifying most problems. (plus Resharper) I only use them to test business logic or complex scenarios, which is what I would argue they are meant for. Not replacing a compiler.

Sure thing! A meta-analysis of placebo-controlled trials found that when disorders are amenable to placebos, the placebo effect is robust and approaches the treatment effect[1]. For psychological disorders, particularly depression, it's been shown that placebos are nearly as effective as active medications[2].

I've researched BTC laundering, because I'm too curious to live.

The main method of doing it is via "mixers", servicss that distribute your BTC among hundreds of accounts, and then pay you back (minus a small fee) via hundreds of other accounts. Theoretically, it's impossible to track a single payment through such a process, since the BTC paid back isn't the BTC paid in.

Another possible security measure woukd be the use of multiple accounts, allowing legitimate purchases and purchases involving physical locations to be separate from illegitimate buys.

The main weak point is your location; once a physical object is shipped to you, it's real easy to tie that to your illicit BTC wallet, and from there, you're hosed.
Oddly, my machines really did creak with WebGL, but it appears as if they have been improving in performance. It's probably not graphic drivers as this ubuntu laptop hasn't had a new graphics driver since 2013. It must be the browsers improving performance.

Game Changer Smart Home Gadget Review
Brain upload is a sci-fi invention; using a T1, DWI, fMRI, EEG and behavioral data to build a realistic model of a subject's brain is today's neuroscience.

I will echo this point. I don't think I've met anyone in the field of neuroimaging who sees mind uploading as plausible. There's simply too much noise in the data for that sort of thing. Even simplified simulations such as the Human Brain Project require so much computing power that modeling a single mind is prohibitive; I can't imagine trying to perform whole-brain emulation accurately and practically without incurring more cost than it's worth. Wetware is good enough for me.
I like this summary of current research on how to do research better. A checklist of suggestions for psychology research journal editors[1] gives a different set of links to current research and current best practice, and is well worth a read too.

You could do that for the whole frame though. The reason it isn't done is because it is essentially a blur and it makes the motion streaky. You might think this would be ok for particles, but the issue won't be particle motion as much as it will be camera motion.

I'd been struggling with migraines leaving half of my body feeling extreme muscular tension 2-3 times a week.

What is your point exactly? I've followed stories around SM for quite a while, and she comes across as living a normal life, only without the debilitating fear-response.

Ask HN: How do prolific programmers go about their daily lives?
When I read the interwebz, I see other devs pumping out code to open source projects like food-to-code machines. They manage open source projects, be on top of the latest trends and even drive the hype causing these other developers to follow suit. Part of me wants to become like one of these prolific developers. I want to learn a lot of things, do a lot of things.

However, in contrast, I find myself out of energy after work that I just drop dead in bed only to wake up the next day. People advise me to do recreational stuff instead of writing more code on the weekends. Even my boss advises against writing code even when deadlines are just right around the corner. Forcing myself a few times, I felt like I was inches away from becoming part of the zombie horde.

How do these prolific developers spend their time? How do they work, do open source while staying healthy and awesome, and not become zombies at the same time?
While using Electon to kickstart project might be a good idea, but it is failing in the long run. There are so many issues, that could be avoided by using some other technologies. Just look at Sublime Text 2 editor, even if they are using Python, program size is relatively small and it performs much better than Atom. Sadly, Sublime is not developed as actively as Atom.
Maybe this can help you?

Carbon nanotubes are seductive. They are very strong, diamond like, in that circularized plane. But when you extend the tube to macro dimensions, you have problems with phonons and the 'rogue waves' that add up over such long distances (relative to atoms). These phonon effects can and do add up to break the nanotube as there is so much energy in the phonon that it overcomes the intermolecular bonds. You can help a bit with an onion layering of nested nanotubes, each a little bit bigger. But that doesn't get you much further. Doping the tubes with other atoms reduces the strength by a lot, but may increase the length. Isotopes of carbon, like C10 or C14, do help a fair bit. However, they tend to be too radioactive to be stable for a project like this. You'd have to continually replace the rope as the dopant isotopes would decay away and the nanotubes would self destruct again. In the end, we need new ideas to help with this. Perhaps some strange electron-phonon interaction? I don't know.
Managed to close it twice, but it took a while. I don't understand how a single application can render a whole (multicore) system unresponsive.

4k/s is still a huge number. This will still involve a rocket 1/4 to 1/8th the power of a ground launch. AND, pieces or not, that thing has to be hauled up the elevator.

So my point still stands. The space elevator will only provide ready access to geostationary orbit. Journeys to more useful low orbits will benefit marginally at best.

Delta-V here's a good map http://i.imgur.com/SqdzxzF.png

The Delta-V required to get from the surface of the earth to leo is 9-10, meaning it requires less energy to launch a payload from the moon to earth's LEO than from the surface of the earth to LEO.
This can even be more optimized using aerobraking, anything that will be launched (or flung) from the launch platform of the space elevator will have higher orbital velocities than an object in LEO so what you really need to do is to slow down.
Because there is still a pool of gravity the object will be in free fall so it only requires relatively small delta-v to bring it down to a lower orbit and you can use the atmosphere to both slow it down further (which can cut down on fuel) and if you design your delivery vehicle correctly can even get into very interesting orbits cheaply by skipping on top of the atmosphere and using the earth for gravity assist.
It's disingenuous to suggest that the solution is simply keeping them off the internet. Their own proprietary network cables/radio comms can be spliced into and reverse engineered when running through public places. Low-level employees can be tricked into plugging in flash drives (i.e. Stuxnet).

When you're building a target, security aneeds to be designed for across the board. If you want to shortcut your way out of that, don't use general-purpose operating systems and don't build networks.
Shouldn't be a surprise, the CIA has been involved in the art and media world for a very long time. Here's what the first Google search turned up:

http://www.independent.co.uk/news/world/modern-art-was-cia-w...

"For decades in art circles it was either a rumour or a joke, but now it is confirmed as a fact. The Central Intelligence Agency used American modern art - including the works of such artists as Jackson Pollock, Robert Motherwell, Willem de Kooning and Mark Rothko - as a weapon in the Cold War. In the manner of a Renaissance prince - except that it acted secretly - the CIA fostered and promoted American Abstract Expressionist painting around the world for more than 20 years."

Of course modern art also is a great means to throw lots of money around, which is probably a bonus for these sorts of programs.

If you don't mind me asking could you comment on what effect this drug has had, over the past couple years, on your fear-responses? Not talking about phobias, but normal fear-responses.
It is a nationalist behavior and I find nationalism weird. I concede that I say that from a place of privilege, in some regards, because I was born and raised in the US, which also has a number of weird and uncomfortable nationalist traits and behaviors. I also find the behavior of the US distasteful, to say the least. But, that's not the subject here.

I believe it is wrong-headed to invent new terminology for something that has a universally recognized meaning. "email" is not American cultural imperialism, it is a powerful democratizing force that serves the whole damned planet. I'm not opposed to efforts to distribute the responsibility and decentralize control over Internet resources, in fact I support them.

Inventing an OS from scratch, when there are several international and Open Source or Free operating systems already developed in the most democratic/meritocratic fashion imaginable (with occasional flaws due to human fallibility), is nationalist bullshit and should be made fun of. The kind of thinking that leads to that sort of behavior and attitude deserves nothing but scorn and disdain. I make fun of North Korea, too.

What is the rate of ultrasounds in these countries? This deformity is very detectable. I know that the only treatment, if one can call it that, is termination, but this may be important in coming years.

In many communities mothers would commonly opt to terminate these pregnancies. It's harsh and vicious, but it does happen. We need to think about such sociological differences when predicting this disease. The wave of birth defects hitting Brazil may not be replicated in countries where ultrasounds are standard and attitudes to termination differ.
You are right jumping off at LEO altitude would be silly. Which is why you would go to GEO then transfer to LEO. GEO is something like 35,000 km high. You burn your rockets to fall towards low orbit, then pick up all the velocity you need falling towards LEO. Burn again once at perigee (or aerobrake) to steer your orbital path into circular rather than elliptical.

A transfer from GEO to LEO is significantly cheaper than reaching LEO from the ground. Additionally transfer from GEO to anywhere else in the solar system is really cheap. It is hard to overstate just how much of an advantage a space elevator would be in reaching any location in the solar system including LEO.

The only disadvange is travel time. Rockets to 300km get there quickly. Elevators to 35000km get there slowly.
LEO is useful for current satellites. But not that useful for moving human influence beyond Earth's surface.
Shamir's secret sharing in Rust
I'm talking about the complexity of what the kernel-level thing is implementing. It's pretty easy to make a secure Hello World program, even if it's running in kernel mode. It's arguably impossible to make a secure implementation of the linux API, which is not even formally documented. The x86 spec is not simple but at least there is a spec. Floppy driver local root is a good example - the linux kernel suffers from that, but a hypervisor might well not even implement a floppy driver.
