It's hard to accurately measure adoption level mostly because of the decentralised nature of Bitcoin, but looking at the transaction volume is a really bad approach. One individual sending money back and forth can generate tremendous volume (similarly with exchange moving their funds between hot wallet and cold storage). Same goes for transactions count (if you are moving big enough funds you don't have to pay fee), plus there are things like satoshidice or reddit tip bot that tend to move towards off-blockchain transactions now.

Damn Cost of living of Indian cities are f---- cheap. Had a hard time finding cities outside India cheaper than inside India. The lowest I came to was Kolkata the cheapest in India. Even many African cites(like Nairobi) were more expensive than Indian ones.
Wonder how much the data is accurate.
Ok, now here's a question: are there any textbooks introducing model theory and talking about these sorts of topics that don't rely on preexisting knowledge of abstract algebra? Not that I don't want to learn abstract algebra, but I don't even know a good textbook to start that from.
the $ god.
It strikes me as odd that you are so against this topic yet you have never had to deal with these rules/associations.
That's true. Still 100% growth per year is not exactly 'no growth'.
Yeah exactly. I do think however a method where they automatically repurchase credits when it runs low such that it just ends up costing something like double a normal instance when it does run low.
True, but the m1.small had instance storage as an option. Since there is no m3.small and EBS is out of the question, it looks like I'll be moving my m1.smalls to m3.mediums.
I don't think any merchant is indifferent about fees.
Ask HN: Prototype Week 2 – Get Leads From Social Networks
Hello HN Community,

I recently posted another entry on HN to get feedback on a quick prototype we built, to get genuine leads for businesses from social networks. (https://news.ycombinator.com/item?id=7927274)

That version was a very basic prototype with rough data, UI and was show casing the concept of the product. We got really got good and important feedback from a so many of you on the HN community and also got a lot of feedback from other places.

So we are thinking of taking the help of the vast community we have on the internet, to actually help us build this product, by taking weekly or bi-weekly feedback.

We did some improvements for our next iteration and made an actual working prototype of the concept. The changes we implemented in this iteration:

1. We included leads from twitter.
2. Modified the homepage a bit to help understand what the product does.
3. Added a video preview on the landing page to encourage people who are sceptical from signing up.
4. For each lead, we have a detailed view where the lead message is mentioned, about the person enquiring about services, and a status of the lead saying how many people are contenting for it. The user can reply from within the dashboard itself.

We would love feedback from all of you. If you can help answer questions like, what problems do you generally face while looking for leads on twitter? What other features would be useful while looking at leads? What other details would be useful? Any other feature which particularly helps you in getting more leads and increasing business.

Looking forward to your valuable comments :)

Thank you so much!

That increases the flexibility, but afaict doesn't help with the upgradeability angle. When Amazon passes along the technological dividend by creating new instances with a better price/performance profile, it's usually as new family types. So your reserved t2.* instance can swap with other t2.* instances, but won't be able to take advantage of any t3.* instance that's introduced in the future.

It's not a huge deal, just something to take into account when projecting out costs: the 3-year reserved instances are locking in today's prices until 2017, in return for a discount over today's non-reserved prices. Whether this produces long term gains requires some assumptions about how the market will change over the next 3 years.
I mean, e.g. buying $800K worth of bitcoin in 15 minutes, so that you can increase the price and then buy $5M worth of goods NewEgg - would $800K in fifteen minutes press newegg's btc-denominated price well below wholesale on those same electronic goods?
Sous-vide won't work for breads. The best bread is going to come from an oven that's using heavy convection current to crisp up the outside. A brick oven does this, as do the more modern convection units.

If you want to see what's new in convection cooking, check out the Turbo Chef Fire. This is a commercial piece of equipment, but could eventually be adapted for home use:

Absolutely, but the numbers are still incredibly low. The customer adoption is only at a few thousand transactions per day. Those numbers would have to go up at least hundredfold for Bitcoin to be taken seriously as a currency.
It interfaces to a number of solvers, both commercial and open source. According to this page [1] it currently supports:

COIN Cbc/Clp, GNU GLPK, Gurobi, Ipopt, Mosek, NLopt

So you can use it to generate models that are solved in Gurobi if you want. Or you can use the available open source solvers.

Of course, that's the cost. But how much do you have to spend in bitcoins to drive the price up that much?

e.g. buying $800K worth of bitcoin in 15 minutes, so that you can increase the price of BTC and then buy $5M worth of goods NewEgg - would $800K in fifteen minutes press newegg's btc-denominated price well below wholesale on those same electronic goods? (including to cover what you overpaid for the btc to execute your position.)

Of course. It does vary on a country to country basis. I believe most countries consider BTC an asset rather than a currency, thus incurring the capital gains tax.

Sweden for example does, and I believe Norway as well. Funny that, Scandinavian countries usually have similar legislation. ( http://blog.btcx.se/bitcoin-nytt/dags-att-deklarera-bitcoin-... )

There are excellent Julia bindings to CPLEX, Gurobi, and many other optimization libraries: http://www.juliaopt.org/. At some point there may be pure Julia linear programming libraries, but initially it's much more fruitful to provide a consistent shared interfaces to existing libraries than to reimplement them.
Lets be honest about the problem and this isn't some slashdot-esque rant:

a) Windows is a piece of crap when it comes to staying clean. If it wasn't, Microsoft wouldn't have to go after people like this. Not joking but I clean out a fair number of PCs every year and they are crawling with malware.

b) Users are dumb and install any old crap on kit if prompted to. Microsoft's SmartScreen did very little to prevent this.

In the fallout from this, people are getting hurt. End users are getting their PCs and data stuffed and companies like this lose their reputation and business because they are a convenient mule (as are the end users) for malware pushers who's job has been made easy.

And don't give me the crap about probability based on the sheer number of windows machines or the plain bullshit security statistics. They're a pretty easy target as the architecture of Windows is incredibly complicated and they're playing plug the holes rather than designing it properly to start with. For ref, I know the NT kernel, win32 and CLR inside out and no longer would I poke it with a stick.

So, there's nothing here that's unique to no-ip.com's case. The problem is that Microsoft spewed out crap for years and people are suffering because the only way they can contain it is to scorch the earth.
> The service sector jobs I have experience with; technical support, can often be done from anywhere.

The problem with this type of service sector job (remote technical support) is that, since it can be done from anywhere, it is just as amenable to outsourcing as manufacturing. Think about it this way - if a job can be "outsourced" to the Midwest, whether it be manufacturing or service sector (i.e., tech support over the phone), it can be outsourced to China or India.

So to be clearer, when I said service sector jobs, I meant those that require physical proximity. After all, the basic problem we're facing here is that a lot of American workers simply have no competitive advantage over foreign workers (after factoring in the lower wages paid abroad). Therefore, those workers need to be in an industry where they can exploit an unassailable advantage of theirs - they can be physically proximate to the people they're serving in a way that no one in another country can.

But such an industry doesn't exist right now (at least not at the size necessary to support all those unemployed people), because of our housing and public transit policies. If those policies were changed, allowing for cheaper and better services to reach the upper middle class, you would see the rapid growth of a new market, one that would really help funnel money from the upper middle class down to the lower classes.

Of course, in the long run, using physical proximity as the sole competitive advantage is not a good social policy, since it will lead to social stratification. Therefore, we also need to quickly reform our education system to ensure that the next generation of workers is broadly competitive with foreign workers, rather than only the top 20-30% of American workers doing jobs that could be outsourced but aren't, because the American workers are truly better at it than their foreign counterparts. But in the short run, we can't reeducate all those people in their 20s, 30s, and 40s, who still have decades of work ahead of them, but have long since exited the educational system. They need jobs, and they need them now, if you don't want mass social unrest and economic collapse.

> The American middle and upper classes want to pretend that the lower classes don't exist, and plan their cities accordingly.

I think a lot of this has to do with white flight and high levels of lead in gasoline coupled with high rates of driving, which led to very high crime rates in cities in the mid-20th century. But crime rates have been dropping in urban locales all across America for the last couple of decades, and affluent youth are more willing to live in (and even raise their own kids in) urban environments than their parents or grandparents were.

For example, this article[0] was posted on HN just a day or two ago. If this trend spreads across the nation (which would still require a concerted and extended effort), we could see a dramatic paradigm shift that allows both the upper middle class and the lower class to coexist in urban environments.

I didn't read this as a critique to the importance or relevance of logical thinking. Nor to smart people's arrogance. But as the dangers to rationalize as a tool for self-dellusion.

Depending how do you feel, how your emotions are, you might want to protect yourself from changes, from disapointments, from "everything-is-wrong-start-all-over" situations. So when you are smart, in this definition, when you have highly developed rational thinking; then you use this to create a illusion that keep you in your comfort zone. Because you can rationalize pretty much everything that happens in the world.

I would say this is not a "curse of smart people", just the particular tool these smart people, according to the author's definition, use to self-dellusion. Other people, with other intelectual resources, use their other resources to self-dellusion all the same. The point is, you have to try to find out when you are on a state of self-dellusion, whatever resource you use to prolong it. In other words, smart people may not be wise. Just as any other "kind" of people.

While I agree that trying to actively break one's theories is a thing that should be done by smart people, I think that in the general sense of smart meaning "possessing raw intelligence", it is not something that I can say that smart people do in general, nor is it something you have to be that smart to do.

Intelligence and education have the effect of greatly increasing the number and variety of "things you can think", exponentially so. Unfortunately the exponentially-vast-bulk of such new thoughts are also wrong. Many of them grossly and obviously so (the vast bulk are new ideas that are syntactically-correct gibbering nonsense), but there's a much more dangerous and still very large fringe of wrong ideas that require one to dig into reality to determine are wrong. And what I often find myself calling something like the Prime Danger of Intellectualism is that our education system is happy to introduce you into that vast space of new ideas, but while flirting for a while with ways of determining their truth, a lot of intellectual tradition in the last 50 years or so has given up on it (in many cases wearing this surrender as a badge of pride!), leaving many modern intellectuals adrift in a massive sea of ideas with no compass, no sextant, and no map. It's a sad and frankly dangerous state of affairs, and it is the default in the intellectual world right now, unfortunately. I know that's a bold statement but once you learn what to look for you, alas, see it everywhere.
Thread.com (YC S12) - Software engineer who loves product (Python/Django) London, England. https://www.thread.com/jobs

We're a startup trying to reinvent retail so men can dress well without being subject to the horrors of the high street or having to trawl through millions of items online. We do this using a combination of powerful algorithms and human stylists.

You'd be joining a small, highly technical team with a ton of startup experience (the founders have started and sold 2 companies before). You'll be one of the first technical hires and get to build and own huge parts of the product and work on the core algorithms.

One of our ancillary goals is to build one of the best engineering cultures anywhere, and we'd love you to help us do that. We launched in October and user and revenue numbers are scaling extremely quickly. We're backed by a collection of the top investors from London and Silicon Valley as well as Y Combinator.

We're especially interested in people who are interested in founding their own startup one day. We view working at Thread as a founder bootcamp where you'll learn about all parts of starting and growing a startup.

Want to learn more? Check out https://www.thread.com/jobs and you can see some of our code at http://dev.thread.com/

===========================
====== What we do =========
===========================

Strategic Maritime Risk Planning (waze for ships, https://www.waze.com/)! We’re working in the largest, least sexy, most invisible industry in the world — 90% of everything has been on a ship at one point in time.

The problem -> To try to decrease costs, carries have been increasing the size of container ships. The only problem there is that as container ships get larger, the variability in the global supply chain goes up (e.g. a large ship being late causes a headache to more people than a small one).

How we fix it -> We track every ship on the water and run a bunch of analysis on our data sets so that we can help our customers smooth out the rough edges. (One company we're working with spends 6.5 mil every month on “late fees” because of these rough edges).

===========================
===== How we do it ========
===========================

Web/data stack -> clojure + postgres/cassandra/redis/rabbit + ruby on rails + hadoop/EMR + node (we’re a SOA shop)

Mobile -> iOS, android in the near term

Algorithms -> a dizzying mixture of oldschool and newschool techniques ;-)

===========================
====== And the rest =======
===========================

We've got some very interesting partners and customers (ranging from telcos to enterprise software providers to regional and international logistics companies). We also have some top tier investors (a16z)!

Looking for help on mobile, frontend, and data science sides! Would be thrilled to find a CTO to grow the tech side of the company with me, but I'm also happy to find engineers who just want to build great things.

If this sounds interesting, please shoot me an email at marc@weft.io!

StoryWorth (https://www.storyworth.com) FULLTIME, SF, YC-funded

I'm hiring for two founder-level roles at StoryWorth: Head of Marketing and Partnerships, and Head of Community.

StoryWorth makes it easy for people to privately record their family stories. Each week, we email our customers a question about their life, for example “What do you remember about your grandmother?” or “Tell me about the day you got engaged”. All they have to do is reply with a story, either by email or by phone. We save their stories and share them privately with their family.

We have a launched product with paying customers across the country who love our service. This is an opportunity to be part of the founding team that is going to help every family in the world record their story for generations to come.

You're a good fit for these roles if you crave a ton of responsibility on a small team. You'll get to define your strategy, and then you'll actually get to execute on it. If you're the kind of person who learns by doing, you'll be learning faster than ever before.

If you're interested in either position, I'd be happy to tell you more about each specific role. Send me a short note about yourself at nick@storyworth.com, I can't wait to hear from you!

With Software Eating Hardware, Silicon Valley Enters "Hard" Times
So, I'm a lawyer, but not at all a tax lawyer.

I was talking to a tax lawyer the other day, though. I told her that I heard a lot of public-interest journalism projects were getting rejected for tax-exempt status, and it seemed like a problem in the tax laws -- we haven't adjusted to a world where a lot of journalism is done by non-profits. A lot like this story, but with journalism instead of software development.

She said she had looked at some of those applications, and she would have rejected them too. She thought the problem was journalism startups haven't figured out that they need to talk to a tax lawyer before filing important documents with the IRS. (And, yes, she's donating time to help with that, incidentally.)

Like I said, I'm not a tax lawyer. But I would wait to get a perspective from someone who knows this field before I concluded that the IRS is really opposed to free software in general. And I would do this kind of thing through a lawyer who specializes in it. Remember that you're helping out more than just you -- if you do it right you're paving the way for people like you. If you do it wrong, you're inviting bad decisions with broad statements like the ones quoting in this article.
The irony is almost overwhelming.
