Well that was fascinating, and not at all what I expected from the title. The article is about the English physicist and mathematician Lewis Fry Richardson:

Richardson decided to do a “hindcast,” so his results could be compared with real weather on a target date in the past. He chose the weather over Central Europe on May 20, 1910—a date for which Bjerknes had already published a trove of data about temperature, humidity, barometric pressure, and wind speed.

Richardson created a map of the atmosphere over the region, split into 25 equal-sized cells with sides of about 125 miles. Every block was further divided into five layers with about the same mass of air in each layer. (Because atmospheric density decreases with altitude, these layers were divided at heights of 2, 4, 7, and 12 kilometers above the ground.)
Guys, the folder structure is normal for gradle android projects.

I like this project, because it combines appengine, cloudstorage, android & android wear all together.

As you can see it also has a server component which reads the .json files from cloud storage of updated schedules. At least that is what i understand from it after looking around for 5 minutes.

It also contains a GCM (cloud messasing) implementation.

All in all, its a very cool that google open sourced this.
A good way of getting at this is to call things at runtime "classes" or "tags" to make it apparent that their discrimination happens at runtime, not compile-time. The problem is that if you call both things types, you quickly run into a situation where you are essentially talking about different concepts entirely.

Note that most sum-types are implemented by having a runtime tag on which you can discriminate.

Seems the problem is basically one of "physical access to the machine is hard to secure against." Combining with "multi purpose computing device attached to your computer is dangerous."

Would it not be simple to offer up "non generic" USB port support? That is, the problem is that plugging a USB device could be plugging in a variety of things, which makes it tough. You have to assume that every stack on your machine is hardened against attack.

Instead, make it so that a user can designate that a port can only be used by mass storage devices or keyboards. A basic UI could be devised showing all of the ports and what is expected to be plugged in to them. If something different is actually plugged in, it is not allowed to connect.

That make sense? Something like this already exist?

They're contributing nothing of value to anyone...

Except if they didn't exist, then bonds like those sold by the Argentine government would require higher interest rates, because the original buyer would have to assume the entire risk of default, rather than having the option to transfer part of that risk in the future. That'd be bad for national governments trying to raise funds at low cost.
Youngest intern at Red Hat shares his experience with open source
Looking to leave law behind and asking for help
I am a lawyer barred in NY and SC, currently practicing in SC in my own office. My college degree is in Biochemistry and I took Math through Calc II.

During law school (2003-2006) I took up learning some HTML, CSS, and Javascript during my free time. I was able get myself up to building a decent static website at that time, but I am not a front end designer. After being in practice a few years I decided to go back to learning code, taking up PHP, MYSQL, and Javascript again, this time mostly jQuery, and lately dabbling in CodeIgniter and Laravel, emphasis on dabbling.

I eventually set up a website for SC attorneys for automated creation of court forms, which is currently a break even operation.

My law practice is mildly successful, but it has proven very difficult to keep the family budget going when legal fee income is so unpredictable. Law practice is a bit of a mismatch with my personality, as I do not have the aggression that some other litigators have, so while I do go to court occasionally, my practice is mostly transactional. Thankfully my wife has a good job that has kept us going quite well.

I want to try to take the next step here in the coding area and see if anybody would like to discuss a remote coding/developer relationship. I would shutter my law practice for such an opportunity. Admittedly I am still in the learning stage, but I learn quickly. Thanks to all.

I'd be very surprised if behemoth automakers managed to finish an agreement in less than two months, when it can take years in other cases. I'd also be surprised if the automakers wanted their names thrown around by Tesla before anything was official.

I don't think they envision that being "the primary purpose" of the jobs being guaranteed. The notion is "find things of value that are not being compensated, employ people to do them". I am highly skeptical, however, that a government bureaucracy can consistently find such work in the face of a guarantee of employment. Yes, we can think of examples. But 1) many of those examples fade in the presence of a basic income (helping the poor is a for-profit activity when the "poor" can pay you to help them), 2) actually quantifying the number of opportunities these examples represent is nontrivial (it may have been done, but I haven't found it in this discussion), and 3) if these things genuinely provide value and we want them done then we can still pay people to do them without providing a job guarantee.

The point is, they are getting hit multiple times with the "untrustworthy borrower bat" for a single incident in 2001 and are now being forced to screw all of their borrowers and not just the ones who refused to play ball in 2001. Because NY law.

That is like saying "Oh, you can pay none of your debts until you pay the ones you defaulted on already in 2001."

Nope.jpg.

That is f'ed up.

They defaulted in 2001. You don't get to come back and say "Oh, but you have to pay us anyway or we will not let you pay the debts since then either."

EDIT:
I'm amused by the downvotes given that is how bankruptcy law works most places. You default one time. The zombie borrowers don't get to come back later and demand money later, enforced by the courts.

I don't understand why S&Ps rating matters, except for in the cases of US state or federal investments where some of the ratings agencies have been written into statute. Everybody is as familiar with the Argentinian situation and how it has developed as S&P is, and they have the ability to make their own judgements about whether they want to buy Argentinean bonds.

The danger to Argentina is that the US government has declared that they're holding hostage the bond payments that Argentina has agreed to and wishes to make.
How solar energy storage could make Tesla much more than an automaker
> Wouldn't it be more fair to say endemic corruption and decades of misguided plans that swung too hard to socialist, then capitalist and then again socialist policies created this?

It would be fair to say that those caused the 2001 default. Which was a real default, but not a catastrophe; defaults happen sometimes, Argentina negotiated a settlement with (most of) its creditors (who had known all along that their investments carried a certain risk), and life went on.

What we have now is a tragedy where the overwhelming majority of Argentina's creditors were reasonable, accepted the settlement, and want to get paid, and Argentina has the money and wants to pay them. But the "vultures" are using a legal technicality to stop that payment from going through, in the hopes of extorting more money from Argentina. And sadly the US legal system is abetting this.
There is a difference between, on the one hand, needing something done and hiring people to do it; and on the other needing to employ people and finding things for them to do.
Why does Argentina struggle so with these sorts of problems?

It seems like a country with enormous potential. Lots of resources, limited security threat, amazing climate.
I see it similar. That is also the reason, that countries with high risk are paying much higher interest rates. Those rates are always defined as "payment" for the risk of loss. So it is a little weird, when funds now find a way to get out of the risk and earn 16x the money they spent, just because of their good arguing before some courts.

Third replication then?

This stuff has been hovering (pun intended) at the edge of detection for some time: spinning superconductors, this thing, etc. all claiming to provide evidence of tiny amounts of thrust in apparent violation of standard conservation of momentum. Obviously skepticism is in order, but either something is very wrong with all these experiments or there's something here.

What's interesting about this one is that the original inventor has something resembling a theory. It may not be a complete theory, but it tries to explain it via relativity in a way that makes physical sense.

I'm always really skeptical of these things, but not in the knee-jerk total dismissal sense. I just say show me the replications. They're doing the right thing. Now we need more people to build these and test them under different conditions.

The ultimate test would be to launch one, since you can't really screw up detection of a big delta-V change in space.

I couldn't believe this, so I checked around a bit.

According to [1], the cost for offsets are $5.50 to $29 per ton of CO2. According to [2], 1 kWh produces 2.08-2.18 lbs kg of CO2 when burning coal (0.94-0.99 kg). Thus, the cost for the offset is about 0.52-2.9 US cents/kWh, or when using different power sources[3], 0.32-1.7 US cents/kWh, hence your number is about right.

Now I guess the next thing to check is how solid those offset efforts really are. Also, probably they are cheap because they are the low-hanging fruits, I suspect that if everyone would offset their usage, the offset costs per kWh would become much higher. Thus, your assertion that the world would look almost identical if everyone would pay the true cost may well still be wrong.

Debtors couldn't rely in the completely corrupt Argentinian judicial system.
That's what it would be like if this were anything but a holdup. The US government is intervening in the market and preventing bondholders who have agreed on a change in rules from receiving their bond payments, rather than letting the market set the prices. That's the opposite of what you describe here.

edit: What I'm saying is only crazy within the bubble of this thread. It's also the opinion of the US government and the American Bankers Association.

http://www.bloomberg.com/news/2013-01-04/bankers-group-suppo...

"'Permitting injunctions against these trustees that preclude them fulfilling their pre-existing obligations whenever expedient to enforce a judgment against the debtor will have significantly adverse consequences for the financial system,' the ABA said in its brief."

A difference here is that rickshaws tend to be independently operated, somewhat differently from the incumbent taxi services worldwide that have dispatch agencies, who are directly hurt by Uber-likes routing traffic directly to the drivers rather than through the agencies.

Here, originally the only operands were customer and driver, and now Autowale, while increasing the number of operations happening, making pretty much everyone happier. Of course, there are a few rickshaw agencies, or bigwigs with subordinate drivers, who play the role of the taxi agency, and probably get angered by this, but I don't think they're unified/large enough to pose a notable threat.

So I would foresee startup-growth/business-model issues being the more relevant causes for a shutdown of Autowale, contrary to with car/taxi startups.
In object-oriented languages, I think the closest analogue to sum types are type hierarchies. It's more verbose and cumbersome, but you can get the same effect through dynamic polymorphism. Consider the example from the post:

type AST = Expr of ...
| Stmt of ...
| Comment of ...

let rec evaluate e =
match e with
| Expr # evaluate the ... of an Expr
| Stmt # ditto
| Comment # ditto

In the object-oriented world, I think this most naturally maps to (forgive me for not using Python syntax; I love Python, but I rarely do much OO in it):

class AST {
public:
virtual bool evaluate() = 0; // again, forgive the C++ syntax
};

class Expr: public AST {
public:
virtual bool evaluate()
{
// Expr specific evaluate code
}
};

class Stmt: public AST {
public:
virtual bool evaluate()
{
// Ditto
}
};

class Comment: public AST {
public:
virtual bool evaluate()
{
// Ditto
}
};

As seanmcdirmid points out, this is not the same, as the discrimination happens at runtime. But, I think it's the closest analogue. Also note that in the algebraic data-type world, we normalize on functions. That is, what to do in order to evaluate any given AST exists in the one evaluate function. But, in the OO world, we normalize on the types; how we evaluate a given AST is spread out over the many evaluate methods.
The background behind the rating agencies is that there are thousands or even millions of investment portfolios out there, with many of them fulfilling very important risk management functions. Pension funds, health insurance, all other forms of insurance, Banks, even many big companies who aren't technically in the finance industry.

Most of them need some form of "low yield safe investment". But it is hard to define what is safe. That's where rating agencies come in. An insurance can promise to abide by such an agency, and that removes a lot of oportunity for bad judgement on the part of individual fund managers.

You may argue whether these agencies are doing a good job at this, but most proposals to get to a better system involve some way of increasing the power of governments or individual fund managers.

Nordstrom to acquire Chicago-based Trunk Club
Nice reply! I love HN sometimes.

What impact does this have on contracts in general?

When I give my word, I keep it. When I sign a contract, I honor it. There's a social contract that assures me that the counter party will too. There's a court system setup to ensure they do. There is force behind that if it is taken even further.

If I should instead shape every contract with a 20% hedge that assumes the counter party will not keep their word, doesn't that introduce a significant amount of inefficiency in the entire system.

Isn't it long term better and in fact just that those who give their word, spend all of their money and then run out take the consequences of it?

For systemic risk to be properly moderated, the individuals or even individual counties must suffer the consequences of their actions. You can opt to not allow this, but you ultimately suffer as a whole when you do.

I see no better way through. Do you?
TLDR;

When restructuring defaulted bonds, Argentina agree to borrow in US dollars. They further agreed:

- to pay all bond holders equally.

- to be governed by New York state law.

- to NOT include a collective action clause in the bond agreement which would have forced minority recalcitrant bondholders to enter a restructuring agreement, if a super majority of the bondholders agreed.

A small minority (2.5-3%) refused to accept the 70-75% haircut the Argentina government was forcing on the bondholders (fyi: previously the largest haircut in sovereign debt was 30%)
