Honestly, I'd get an EIN from the IRS http://www.irs.gov/Businesses/Small-Businesses-&-Self-Employ... For international businesses, it requires a phone call but supposedly it's not terribly difficult. Get a mail forwarding serving so you have a US address for Amazon payments, and from there it's just a matter of sorting out a bank account or US credit card. That might be a bit more difficult, but the easiest thing to do (if a little bit of a grey area) would be to get someone in the States to get a prepaid card like Serve AmEx, Bluebird AmEx, or prepaid Paypal mastercard. All of those cards are prepaid, but they have a routing and account number that could be set up as a bank account on Amazon Payments. The Paypal one would probably be especially handy since it could be funded from a foreign bank account or a PayPal account.
OP did not write that. See here: https://news.ycombinator.com/item?id=8209525
The working hypothesis at the moment is that that type of suborbital hypersonic aircraft is what's being built by the US at Area 51 these days. Certainly the focus of public research funding has had that theme to it.

> In Duo you can pin down any dependency right in the file via require('some/repo@tag'), which is the same as having a manifest with a pinned version.

That will do nasty things for your ecosystem if people start doing that in libraries. You'll end up with version lock on shared dependencies:

- My app depends on foo and bar.
- foo and bar both depend on baz.
- They both specify different tags.

Now your solver has a sad, and your user has a sad.

I think Spotify getting this feature working wouldn't be trivial as syncing audio perfectly across different Internet devices (labtop, PC, tablet, phone, etc) doesn't seem doable. Also, music licensing issues would probably be an issue too.
This is actually incorrect. The space shuttle had massive launch engines because it needed the thrust to get off the ground and into space. But from the words coming out of SpaceX, about 80% of a rocket's fuel is actually expended accelerating to orbital velocity once you're in space.

But, once you're no longer needing to fight gravity so much, it's a lot more efficient to use lower thrust engines for the job, provided you've got the time.

A terrible article about a fascinating subject.

I am inclined to give the benefit if the doubt in the whole " The only place megafauna has survived to some extent to the present day is in Africa where people traditionally have lived in harmony with nature". In many hands that would be hippy happy pseudo racist claptrap. And it might be but the next paragraph points to the more realistic "harmony with nature = avoiding humans"

I have severe doubts about the overkill theory - the fossil record is fairly sketchy and so many species died out within a few hundred thousand years of us arriving on the scene that exact timings are hard to believe. On top of which the practicality seems a bit hard - I can accept that some creatures might be defenceless against men and spears (giant sloths seem likely to lose out) but I am going to struggle seeing sabre tooth tigers as easy prey for man.

Climate change, Eco system collapse and diseases carried by apes and their dogs seem to hold the occam razor prize for most likely explanations. A spear through the kidneys would just be making a bad day at the office worse for megafauna.

Certainly. SQLite is a great example of one. It handles the tradeoff elegantly: reads can be done in parallel but writes have to be sequential.

I don't believe maildir would be described as a flat file.
DocumentDB has a similar looking (maybe not as powerful) interface:

});
Nice find.. will surely try it.
You wouldn't need marching cubes to operate real time - it runs once, generates an iso-surface mesh which can be efficiently rendered in hardware.

“Governments often gain politically from war, even if the war makes no sense”
We weren't generally aware of many of the specific problems at the time. Though, it turns out: a huge number of the bigger problems were actively opposed by presentation of disinformation, from the use of lead in paint and gasoline, to the hazards of cigarettes and tobacco, asbestos, air pollution, CFCs, and now CO2 and global warming. Often with the same tactics and even individuals involved in different battles.

The bigger problem is that humans, as with all life, exists to exploit entropic gradients. Some of these are huge (e.g., the energy densities of hydrocarbons and fissible nuclear fuels), some are much more subtle, including the disruptions caused by introductions of modest amounts of novel contaminants into the environment. It's both our entropic sources and sinks which can be overwhelmed.

And economic growth which comes at a cost of the future to all isn't growth. It's a Ponzi scheme.
Certainly, but it's a good habit to get into, like ``use strict`` in Perl.

Probably the best one I can think of is that it gives you a natural way of looking at gradual typing. Doing gradual typing well is still tough, but you can see it as an obvious consequence of the unityping argument.

Child's drawing 'predicts later intelligence'
Whether it's worth doing, or even possible to do, is highly dependent upon who you are.

As a scientist, I appear to be essentially banned from being on a jury. The last time I was there, my experience consisted of wasting two days sitting in a courthouse, surrounded by people trying to escape from jury duty, only to be dismissed from a jury by the prosecution immediately after stating my profession. In total I said less than ten words. Everything I have been told by others in academia seems to go along with this: scientists are immediately dismissed.

So what's the point of my going? I'd like to be on a jury, and think it's an important civic duty, but the end result is an utter waste of my time that achieves nothing, for which the court insultingly tries to "compensate" me with $15 per day.

Not who you were replying to, but on mTurk 10,000 approved HITs with a 99% approval rating or higher will probably be your best bet. If you are going to put up a lot of HITs, especially if your HITs require special skills, you might want to put up some tasks and assign a special qual to the top, say 10 or 20% of the workers. Then you'd have a more limited group of workers, but ones that you know will do well. (Usually qualification tasks require workers to complete 10-20 of the HITs to get a good idea of the quality of work.) You might sacrifice a little bit of speed, but you'll get better work. Plus, if your work pays decently by mTurk standards, anyone who has the qualification will be on the lookout for your tasks.
It reminds me of that classic Monty Python sketch about the hermit community. I think most people consider leaving society and taking up this life -- but I estimate that most of them would have a second thought when they have to build a fire.

It's funny how often advanced technology has, as its limiting factor, the ability to efficiently cool air. It's kind of promising, I suppose, since to cool air is remove energy from a system and hence has a theoretical negative net cost of energy.
This. I get to think about a bunch of different problems, some of them interesting, some of them difficult or impossible to solve, with a team of malcontents and nutballs. It's like being on a crew of pirates who stress about implementing k-d trees, matchmaking, deploying dedicated servers, build systems, scaling everything appropriately and doing it all as fast as possible. And at the end you ship something which is hopefully magical, possibly something that is shit, either way you have a giant party and tell awesome stories.
One way to look at this is that you have types which classify a structure/theory. In some sense, it works like this—you have generators which allow you to inductively define a large set of "things", then you have laws which cut those things down.

For instance, the theory of monoids gives rise to the generators

zero : AMonoid
+ : AMonoid -> AMonoid -> AMonoid

satisfying the laws

zero + a = a
a + zero = a
a + (b + c) = (a + b) + c

Types can be refined and combined in principled ways by glomming the generators and laws together. Ultimately, what you're looking for is a notion of the set generated by all of the generators satisfying all of the laws plus any "coherence" laws which help to define what happens when two laws interact.

Unfortunately, nobody is very good at this today. It's a goal to be able to automatically achieve the above system in such a way that isn't O(n^2) effort to encode.

No one is using the energy in the air for anything. It is not an important term. You're reading the idea as though somehow the energy from the air is used for something - its not.

The issue with hypersonic flight is that it's impossible to sustain a flamefront (combustion) of supersonic air. So you have to slow down the air before you feed it into your engine, or you flame out. But you've got high velocity air suddenly being compressed - which means you're going to superheat it.

That's also a problem, because the superheated air will pre-burn or even detonate fuel in the wrong part of your engine. Or just melt your air-intakes. So you need to cool it - and you need to cool it really fast because you need a lot of air to make your high-speed engine go fast.

The "cooling it fast" is the trick. Dumping the heat into the liquid hydrogen isn't - you do that because you need to get rid of that heat quickly, and the best way to do that is to take some of that cryogenic fuel you have so much of, heat it up and then immediately eject it from vehicle.
If not, they were close behind, e.g. http://nigelef.tripod.com/tgtacqcb.htm#Radar

Wikipedia tells us why those were initially Anti-Aircraft (AA) radars: https://en.wikipedia.org/wiki/Counter-battery_radar#History

"The first radars were developed for anti-aircraft purposes just before World War II. These were soon followed by fire control radars for ships and coastal artillery batteries. The latter could observe the splashes of water from missing shots, enabling corrections to be plotted. Generally the shells could not be seen directly, as they were too small and rounded to make a strong return, and traveled too quickly for the mechanical antennas of the era to follow.

Radar operators in light anti-aircraft batteries close to the front line found they were able to track mortar bombs. This was likely helped by the fins of the bomb producing a partial corner cube that strongly reflected the signal. These accidental intercepts led to their dedicated use in this role, with special secondary instruments if necessary, and development of radars designed for mortar locating. Dedicated mortar-locating radars were common starting in the 1960s and were used until around 2000."

No, its not.

Right, which is exactly how it isn't like what you said. Because the message it communicates to the reader isn't like what the other one communicates, and the fact that you read it and know immediately that that isn't what is being communicated illustrates that perfectly.

> so long as you need to make special welcomes to groups of people in general the problem persists.

I would reverse those: so long as the problems of racism and sexism -- and the resulting implicit hostility exists -- explicit welcome may reasonably be perceived as necessary.
By all means. Then the government agent will just walk out the building, put on his "private citizen" ball cap, and resume spying using all the authorities any random citizen would have.

That's why I pointed out the state often has much more power, as we wouldn't bother having the state do it in the first place if anyone could do it for themselves.
The basics of your argument are true, but the air breathing capabilities change the magnitude of the effect quite a bit. Saving the oxygen weight in the 'first stage' helps a lot. One oxygen atom has a molar mass 15 times larger than one hydrogen atom. Burning O and H to H2O thus means you have 2/17 of the mass laying in the hydrogen, 15/17 in the oxygen. It's an order of magnitude savings.

Again, look at the Virgin Galactic Spacecraft as an example. The reason why they can go so high without much of anything, is that their first stage is an air breather.

Furthermore, the fuel that you need to bring to go from Mach 5 to Mach 25 is what's responsible for a large size increase of your first stage - to have more fuel to burn at a high altitude / high velocity requires even more fuel at the ground.

Overall, you have to look at an airbreather quite differently than conventional rockets and you have to look at suborbital flights differently than orbital - you can't really approximate it from the space shuttle without going into the details.
I love how they put the most important sentence at the very end of the article:

>>But, Jacob said, the significance of the study is that it shows a new way for scientists to estimate total water loss during times of drought, which would be more difficult to estimate without being able to detect how much the land is being uplifted in dry years.

Because really, the fact that the land has risen a few millimeters, in and of itself, is not important, since it doesn't have any implications (at least for humans). What is important is that being able to measure this increase will allow us to gather water loss data from other regions.
MS can both act in self interest (it is business after all) and do something for the "public good".

It's weird that you think these two marks cannot both be hit in one stroke.
"There is no persistence layer involved for experiment group allocation, so that we could minimize the latency/load on our production services. We left all of the complicated metric computations to offline data processing." Does that mean that the experiment to which the user is allocated is stored through a log in memory instead of being stored on disk/on disk and in memory (through logs)? If so, are there frequent trade-offs between memory/cpu usage in running experiments?

There are a couple of scenarios:

- You want high performance and hence you want to leverage pypy, which has far better support for python 2 than for python 3.

- The libraries that you're using don't have good python 3 support. Flask used to have some problems with 3, but no longer does. Many companies have a lot of code written in Python 2 (dropbox), and hence using python 3 would not be a good idea.

Dealing with a violent encounter
Hi ChuckMcM,

I'm a Program Manager on the Azure Search team. I am going to correct your numbers a bit. Even though you can have a maximum number of 36 search units, the number of partitions you can create (currently) is 12. Partitions, by the way is what you increase to allow you to increase the number of documents. With this limit of 12 partitions, the maximum size of an index is actually 180M documents or 300 GB (not 900 GB as you stated). So far, we have found that the vast majority of customers we have been working with fit well below these limits and in fact even more of the majority fit into the 1 partition (15 M document / 25GB) range.

For a very few customers we have talked to, there is a need for more than this and for this we can actually allocate a much larger system that has much higher ranges. We have an azuresearch_contact email address on the pricing page (http://azure.microsoft.com/en-us/pricing/details/search/) with more details if you need this.

To your other question about racks and search units. You can think of a search unit as a dedicated Azure VM for your usage. For each additional Search unit you create is an additional VM for your use. Each VM has a certain amount of capacity that it can handle. If your needs grow beyond what you can get with a single search unit, you can move the dial up to increase it whether it is increasing replica count to add more QPS / High Availability or increasing partitions to add more documents / faster data ingestion. The way you calculate the number of search units you have is replicas x partitions, where each search unit (during public preview) is $125 US / month. By the way a single replica can handle about 15 QPS which for most customers is more than enough. But even with this, the ability to scale up and down is pretty important to a lot of people. Imagine Black Friday in the US where a retailer gets hammered with searches, yet only wants to allocate increased replicas for that day to handle the increased query load. There is a bit more information on this here: http://azure.microsoft.com/en-us/documentation/articles/sear...

Hope that helps,
Liam
I use an iOS app called, Reporter (http://www.reporter-app.com/). It prompts you with push notifications to answer a set of custom questions throughout the day- Are you looking at a screen? Who are you with? Where are you? How many cups of coffee have you had?

The reports also capture "background" data using the phones sensors: number of steps, temperature, volume, elevation, phone battery, etc.

Its great for lightweight tracking and all the data can be exported in CSV or JSON formats. Reporter can definitely help you track sleep hours, food eaten, and productivity (weight and body fat % can also be captured).
