Initially, I was on-board the whole "yeah, screw you school!" train with the students (presumably left over trauma from being intellectually sodomized by UC Berkeley's physics department), but then I read the prompt 3 in question. And I have to say, I really really like that question because it's not only testing the student on memorized economics tidbits, but also on truly applying learned theory and economics intuition to a more alive problem.

In fact, even though I'm suppose to be slaving over getting onDisconnect to clean up correctly in Emberfire for my boss before the afternoon whipping, I can't help but have fun solving this problem:

1. the gamma (coordination) term is NN because people all have their own opinions and agendas which they have to tell everyone else. In other words, if there are 3 people, person A must tell his idea to person B and person C, person B must tell his to Person A and C, etc., and in total there are 9 "tellings" (aka meetings).

2. The graph of production-v-person and cost-v-person, if plotted onto the same paper, would look like the lower case letter gamma tilted 45 degrees to the right. The most-bang-for-your-buck optimal city size would be were ( g N * N - a * sqrt N ) is largest. If I knew calculus and can do derivatives, I can get N = ( a / 4g ) ^ 2/3 as the answer.

3. A peasant city is one where (a / 4g) <= 1, that is, where talking to other people is really really hard but doing things is really easy (lol just like at my work, where we're all peasants and we slave for months only to have our projects cancelled and the blamed placed on us). "a" and "g" can change with technological improvements, for example, "g" can go up when the society discovers email, the telephone, writing, etc., and it can go down when the society discover facebook of 4chan (and then we all spend our time being holier-than-thou, insulting each others' tastes, and disparaging each others' waifus). "a" can go up with the development of productivity tools; an example of this in the javascript world where I hail from is when jashkenas discovering coffeescript, wycats + tom dale inventing ember, etc. "a" can go down when you get a legal department who insists you can't use X, can't contribute to Y, and I must watch my language F.

Seems to be here to stay, but I can't quite figure out why. The only thing I liked about it when I tried it out was the gotool, but it was hardly a reason for me to switch, given that I find the language itself kinda poor. Sure, it has cute syntax, but doesn't seem to provide much else that I couldn't do in another language, especially with contenders like Rust and Nim, or just plain old C, which is well-supported almost everywhere.

If I recall correctly, that's the favorite phrase of the new minister of finance.
"Give the money to the people". The US did this in the form of tax credits for housing. Germany did something similar in the form of credits for car purchases. This form of giving goes directly toward an industry in need. I'm not sure how giving a blanket check helps. If the problem is consumer spending and IF this is an important driver for your economy it may have some impact but I think the problems the EU were facing were not this. So giving money to the people just sounds like dangerous populism and an action that makes little attempt to rebalance some ailment in the economic system.

P.O. boxes are your friend
What about Shingy?
That's pretty neat it's like the android intent system.

How does the system get the list of all other apps that satisfy the requirement? I'm guessing all apps register with sandstorm server somewhere that has a centralized list of other servers?

It'd be neat to have standard protocols, in the same way we have standard media types.
Sandboxed applications literally cannot send any data by default. They can't open a connection to <whatever server>, no matter what protocol.

The goal, once they've built their Powerbox, is to then implement a set of protocol drivers which the application can use. So it still can't connect to arbitrary servers, but it can ask the user for permission to, say, connect via SMTP to <wherever>, and the user has control over that.

Yes, they could leak anything that you put in them if you allow them to connect to someone you don't trust. However, even if you do so once, most applications will be per-document - you have an instance of your document editor for each document, and they don't know anything about any other documents you have.

In short: applications can only leak what you give them, and only to people you say to give them to. They can't call back to home base without your permission or the permission of someone you've given the app permission to contact. So for all reasonable definitions of "cannot leak data", applications cannot leak data without your permission.

well, short story: individual Cetaceans are, and were, identified with its body marks. Nothing new here.

Is good to remember that Ziphiidae are not "whales", at least not the animal what everybody imagine when thinking in a whale. Those are beaked whales, a totally different kind of carnivore creature. To ilustrate the differences, if whales where kangaroos, then the beaked whales will be tasmanian tigers. To discover a long term relationship between social carnivores is very interesting, but not so striking as the article says.

It's probably as close as you can get to accuracy while still keeping those who passed their high school chemistry classes in your audience.

For the purposes of explanation, the antimuon-electron pair is chemically similar enough to a proton-electron pair to call it an isotope. It has a +1 massive center, with a probability distribution for a less-massive -1 charge cloud.

Deuterium and tritium, two true isotopes of hydrogen, increase the mass of the center by adding neutrons. An antimuon is, I think, about 10% the mass of a proton. So muonium would act a lot like extra-light hydrogen for the instant before it decays.

It would have been clearer to call it an "exotic atom, chemically similar to hydrogen", though. That wouldn't conflict with the common definition of isotope as an atom with the same number of protons as the reference atom, but with a different number of neutrons.

I'm actually not aware of any exotic atoms that are not chemically similar to hydrogen or antihydrogen, as getting an exotic helium-like atom would require forming a +2 exotic center and making two -1 charges interact with it before it decays. That is likely beyond our current capabilities.
First, sorry to hear it, that sucks but it seems like you get that it isn't necessarily about you which is good. Sometimes people take it too personally, and usually it isn't personal, just business, but that doesn't mean it won't still sting some.

Second, javascript is a great skill to have and it is looked for quite a bit. Remote work isn't out of the question just because you aren't a degreed CS person. You said you have some savings. So take 1-2 weeks, polish up the resume, take it easy and start sending out resumes locally if you can find anything and also to remote positions. You might feel more comfortable starting to send out resumes right away and then taking a couple of weeks before you start a new gig, but either way, take a couple of weeks to decompress between jobs. I have skipped that in the past too many times and regretted it later. Also use that time to reassure your bride-to-be that all is good and will work out, tech is a great place to be.

Just a side note, I live in a small city and almost every client, job or thing I have done has been remote or outside my city, so it is very doable. If you go into freelancing, there is a thread from the other day on here about it, look it up under Ask HN, it has some good points from a lot of people.
I am German and have had a very negative opinion of Tsipras. He makes some very good points in this letter and his view seems to be consistent. I can understand his position and my opinion of him has improved a bit after reading the letter.

Nevertheless I see no solution, only 3 possible bad outcomes:

1. Europe loans more money to Greece and we can be pretty certain that they can't pay it back.

2. Europe gifts money to Greece (forgive some of the debt) to temporarily reduce their debt and after a few years we are in the same situation again

3. Greece defaults on its debt (and maybe exits the Euro) and can't borrow money for the foreseeable future.

None of these options looks particularly desirable and imo Tsipras doesn't help the situation when he says to hell with it; let's rehire all these public servant. We don't have the money for that but it wont matter much regardless which possible outcome becomes reality

Hi, lead developer of Sandstorm here.

> That's just marketing bullshit.

No, it isn't.

> Unless the API is magic (and I don't mean advanced technology "magic" but Harry Potter "magic") it has no way of knowing what the application is allowed to send or not and therefor cannot filter.

You're assuming that Sandstorm apps have arbitrary IP network access. They do not.

Sandstorm is based on capability-based security. Any outgoing request has to be addressed to a capability representing some specific permission that the user has granted to the app. A capability might point to another app, or it might point to a specific external host that the user has designated.

More specifically, a Sandstorm app's only connection to the outside world is through Cap'n Proto RPC, which is an object-capability protocol, meaning that an app can only send requests to objects to which it has explicitly received a reference.

https://blog.sandstorm.io/news/2014-12-15-capnproto-0.5.html

https://capnproto.org/cxxrpc.html

Incoming HTTP to a Sandstorm app actually happens through this Cap'n Proto protocol:

https://github.com/sandstorm-io/sandstorm/blob/master/src/sa...

Of course, for backwards-compatibility, we have translation layers so that apps written to use regular old HTTP need not be entirely rewritten. You just have to tweak it to make the correct permissions request first, which has proven not very hard in practice.
I will preface this by saying that I am totally not sure, but my impression was that the EU and IMF loans were to enable Greece to repay creditors in full or close to.
Since there's some discussion in this thead about inequality of revenue between generations, I would mention here Stéphane Laborde's "Théorie Relative de la Monnaie" http://trm.creationmonetaire.info/ or "Currency Relative Theory" https://github.com/informatimago/LatexTRM/blob/master/LateXT...

Basically: instead of performing QE by giving all the new money to banksters, we give a Universal Dividend to all human being, at a rate determined from the average lifespan, so that each human being gets the same relative amount of money during his life who ever he is, and WHENEVER he lives. (Of course, this doesn't precludes normal economic exchanges, and therefore differences in paychecks, but at least the QE are done systematically in a reasonned system, contrarily the aphasard releases of the Fed). (For the European Union, given the average lifespan here, this would give a Universal Dividend of about 500€/month).
SOX on Fish: A New Harm of Overcriminalization
I'm not sure how that is supposed to work. You would have to rewrite every webapp so that it's data can be protected by sandstorm. Which seems hugely impractical. And as long as the webapp has access to it compromising it will compromise the data.

Calling a dissenting party clowns is not helpful. It's also wrong, since they argue their points well and their economics are backed by such people as Paul Krugman. Now you might disagree with him, but would you call him a clown, too?

Greece may have cooked the books but the rest of the EU is complicit in not doing their due-diligence in their haste to include Greece in their attempts to declare 'largest economy in the world'. It was a stupid pissing-match and the EU definitely carries a fair chunk of the blame here.

How does he not hear himself? Also, "Handelsblatt" is missing a letter. Anyway ...

I reject the premise of his letter. He seems to think the purpose of the money was to help the greek people, and offers a more productive way of doing so. That's all fine, but I'm pretty sure the sole purpose of the money was to save the Euro. Whether that's ethical is debatable, but I think it's important to remember that Greece has messed up quite a lot of things without considering how that might effect other EU member states; ignoring at least some of their responsibilities. But that's a different story entirely.

His tone is utterly disrespectful, if you ask me. I'm really not sure who he thinks he is or what he thinks he's doing, but I know for a fact that a lot of my fellow germans aren't gonna like being spoken to in this tone of voice. He mentions fear and anxiety a lot. I don't know what he means by that. We're quite calm, as far as I can tell, and I can imagine that scares him a little.

Germany is one of the riches countries on this planet. We will do almost anything to keep it that way. I appreciate that he needs to sell his own agency to his people, but if he actually believes he can control the fate of his country even so slightly, I'm afraid he's delusional.

Just for the record: I'm neither proud of nor happy about how we treated the greek people, but I'm tired of pretending this is about anything but money.

Some notes:

1. Greece is talking about Germany because it helps mobilize masses. Germany does not decide on it's on on this nor is the most agressive player. Most northern and eastern countries are more agressive in their opinion against Greece. But it helps to mobilize Greek masses with a simple enemy.

2. Greece has defaulted have a dozen times in modern times. This is the Greek way of doing things and will continue, whatever the EU, Germany or the IWF thinks and does.

3. People in Greece don't think of taxes as something you have to pay. Many Greeks stopped paying taxes the last months in anticipation of a new government. This will not change and is the main driver for Greek defaults.

Agreed, reminds me of a test I took in a stress analysis class (mechanical engineering at Arizona State University in the US). We had covered thermal expansion of unconstrained objects, as well as those held in certain dimensions by fixed walls. On the exam the professor wanted to cover both so he had the walls placed a small distance away.
Most students flipped out because they had not seen an example of that exact situation, but a moment of thinking shows that the problem should be broken into pre-contact an post-contact parts. This professor had the highest drop rate I have seen (around 30%), but his insistence on comprehension over memorization made me learn more than any other class I took.

> That's all fine, but I'm pretty sure the sole purpose of the money was to save the Euro.

It actually hurt the Euro. What it did do is save/prop up some very large French and German banks. Nothing like gambling with other people's money to see if you can come out ahead and ask for a hand-out if your plan fails.

http://www.bloomberg.com/news/articles/2011-06-05/german-ban...

The cynic in me says that no single politician that supported the bail out ever expected that money to be paid back. Greece would have to completely change its culture in order to be able to pay those loans back.
No, good SEO is designing a page that is perfectly crawlable by bots (this is still difficult for most people, especially for larger websites and people who aren't familiar with webmaster best practices), and researching/creating/promoting relevant content to attract links.

There are of course shady people in the SEO world, but most of the "one cool trick to help you rank better" tactics are long gone as Google has done a pretty good job squashing those through algo updates.

Saying "SEO is still a service to break search engines" is incredibly misguided - Organic search is a ridiculously powerful growth opportunity for brands as ranking #1 for proper keywords can be a multimillion dollar marketing value add. To sell that short is incredibly foolish, and every brand worth their weight should truly believe they deserve to rank #1 for relevant terms, why not work to achieve this?
The cold fusion race just heated up
> It seems to be more difficult to come to consensus in purely written communication

I agree that some conflicts are much better handled via synchronous voice conversation. And I think that's acceptable, if not desirable. However, I make sure that after the call we write down some notes what decision we made, and why we decided the way we did. This makes sure that parties not present at the meeting (i.e. other developers, and our future selves) can pick up the context quickly and save us the pain of working through the decision process again.

And then there is always the issue of dysfunctional team communications where the channel doesn't matter. In asynch conversations poor/obstinate communicators don't need everybody in the room to keep adding to a controversial conversation. So you just can't stop them..

And I just learned a new word: 'in·tran·si·gent': unwilling or refusing to change one's views or to agree about something. Thanks.

> more awkward for decision-makers to assert themselves

That has probably more to do with team culture than the communication channel used. I'd think that a capable and respected decision maker can assert themselves easily via written word.
Ooh, that could lead to some very interesting attack vectors. :D
Exactly. It's about controlling the politics of Greece, because the EU/Germany don't trust them to change and use this to put pressure on Spain and Italy. Tsipras hinted at this fear himself ("returning to the bad old ways").

Still, the price being payed for this by Greece is too high. There has to be a better way. For example: Better contracts, better checks, and active support by investing in parts of Europe that are struggling. Or by creating a Fiscal Union, effectively admitting that permanent transfers are needed. This would be more honest, but German politicians are too afraid that this will be unpopular with voters.

But I fear, from what you wrote, that you fell into the same trap as @gmarx above.

The claim in the exam is that the total coordination cost is above quadratic, i.e. proportional to N^b for some "b" strictly larger than 2. (Because per-capita cost is proportional to N^a for some "a" strictly larger than 1.)

This is not what is typically assumed in complexity theory.
I've been seeing a good number of google maps listings hijacked by marketing companies. One restaurant a co-worker of mine advises in her spare time contracted a company that provides online food delivery lead gen. services (similar to grubhub, but not them). They take a cut of every order.

The restaurant owner is a friend of my co-worker and asked her to help with their website and local marketing to drive more business in addition to the lead gen company. When she dug into it, turns out the lead gen business conned the hostess into turning over the google maps account via the phone verification and everyone that looked up the restaurant in google to order went through the lead gen service, where they should have gone directly to the restaurant, saving the restaurant the lead gen commission.

While one might argue that this is legitimate, the owner of the restaurant had no idea and felt cheated.
