Not by too much. M2, which I think is the relevant money supply in the US, is $8 or $9 trillion.

If I remember, the US is about 1/5 of the world economy. And some random graphs suggest the world money supply is roughly $60 trillion.

New CDC App Turns You Into A Disease Outbreak Detective
According to the efficient market hypothesis (which you may or may not agree with) the only guide you have as to how much something is worth in the future is the current price, as well as "future information" which is not currently available (if it was already available somewhere, it would already be priced in.)

In other words, no one can answer that question for you :)

So I thought this article was pretty opaque. They didn't really discuss the subsidy enough. They just said there was a subsidy that allowed the banks to borrow money at a reduced rate. Who is giving them this preferential treatment? How do those particular banks get that subsidy? Why not charge all banks the same rate and let the size of these banks eat themselves. It's not a hard concept to swallow if you've had economics 101. Law of diminishing returns which happens to any business when it gets too large. But, I think it didn't really layout a case for why this subsidy exists.
What would be the best way to assess the quality of cheap computers from China? I am thinking of buying a number of android tablets. For instance, http://www.globalsources.com/NEWS/7-inch-Android-tablets-122...
In some sense the thesis of the article makes intuitive sense. How can the banking sector really have much of a margin since they are dealing with the ultimate commodity product, money!

Trading is a zero sum game, all the banks can't make a profit doing it.

Banks provide quasi governmental services to society, so one could make an argument that they should be subsided in some way, or that they have to be subsided! Their role in the economy is too fundamental to not have.

I've come across arguments that banks should just be turned in to utilities.

http://www.nakedcapitalism.com/2011/08/should-banks-be-publi...
Well, this is going to be an interesting watch!

The fundamental issue is that holding is what increases the value (because, really, it is an exchange medium; the world still ultimately prices pegged to their respective local currencies, no matter what any bitcoinite insists), and as the value increases, you are incentivised to hold.

It is going to be interesting to see what happens when the bubble bursts (and it will, to some extent), and how big it gets, as most of the bitcoins held will probably be owned by users who have been through a crash before. This could mean we are only just starting the bubble-- increased confidence may let it grow far beyond the previous one.
"I very strongly doubt we will see a crash anything like we saw last time"

This assumes that all crashes are built the same. In fact they are not. An an example, increased usage and profile also greatly increase the likelihood that governments come in and panic investors.
If you have a mid-sized Rails app, with say 2-3 developers working on it, a full time security engineer would probably be overkill. Anyone have any recommendations of services/consultancies to be able to tell "oh, someone is hacking us right now" or "our page which has stripe.js on it has been compromised"?

I'm hoping for automated tools, services to install on our servers, or security auditors who have an out of the box package.

This is the only automated tool I know about: http://brakemanscanner.org/
The difference is that with gold, there's an actual intrinsic demand backing it. There's a cultural demand (indian weddings) but also a real industrial use for gold. There is zero use for bitcoin outside of the financial context.

The US Dollar is backed by the united states government and economy, and enough people have faith in both to confer present value and future value.

There was a massive effort to introduce a new currency backed by physical silver (by the Hunt brothers), which never gained much traction despite the cash thrown at it.

Right now the people investing in bitcoins are speculating that they will stay. For them to stay, there needs to be confidence that it will retain some sort of value, and the early people are at best described as speculators (no one is betting the farm on BTC).
Could this be used (wholesale) to get around the US ban on online gambling? I read that the major sites were busted and execs taken to US courts but maybe this is more secure and harder to track? Probably enough serious gamblers and gambling sites will probably take the chance with currency fluctuations.
I feel it's a little disingenuous to call it a "subsidy" since the taxpayers aren't actually writing the banks a check for $83 billion. But the key point is still spot on: without the implied backstop of a government bailout the banks would pay what everyone else must pay to borrow money, etc.

Too big to fail is simply a euphemism these days for "The government will take care of everything no matter now stupid and reckless we act." This attitude really must go. How should that be accomplished? I don't know. One thing is for certain: the banks will drag their heels kicking and screaming should someone try to change the status quo. And they'll probably get their way - but it should still be attempted.
This is how you shut your company down
> Some people believe in the success of US dollars. They invested heavily in the future of US dollars. This proves US dollars are going to be valuable.

You realize that you're sorta making his point? US Dollars are not going to be successful because some people have "invested heavily in the future of dollars." But that's the reasoning given 2 posts up that was poked-fun at in your parent.

You know, I was buying a sandwich with cash at Subway today and I suddenly thought "you know, this would actually be less cumbersome with bitcoins."
I'm a bit confused as well. I feel like this is a digital fridge where I can stick stuff (and possibly my friends too?). Maybe it's more like a Pinterest without the masonry?

My guess is that it's more likely to be another cryptocurrency that becomes the standard.

Out of curiosity, what are the existing or potential differences between cryptocurrencies? What does the competitive landscape look like?
Are there any POS systems that use bitcoins? Any other way in which small transactions can be conducted en masse with BTC?
It's pretty simple. Firebase has pretty decent docs and even when they didn't (I was at their pre-release hackathon), it was still extremely simple to get up and running. Just scope their site.
If that's the case, "Digital Fridge" would've been an awesome name for this.

I must have missed the limited ram access when I browsed the slides the first time, I just assumed the youtube Game of Life proved they were poking ascii 'X' chars into video ram at 0xb8000 or whatever. Is there a trick/cheat to how that visualization was done?

Edit: browsed around the code some more and it seems the ascii visualization stuff is done in regular c/asm polling the "virtual game of life" mem(?)
Well I suppose it really boils down to taste, but two things come to mind:

1. LOOP -- (loop for i in some-list maximizing i) is just the beginning of nice iterative constructs in CL.

2. Conditions -- continuations are a building block for this, but it's nice to not have to build it up yourself. Agents in Clojure are pretty good also, but not applicable for any exception (correct me if I am wrong, I am not as much of an expert in Clojure as in CL).

Again, just a matter of taste. Clojure and Racket certainly have advantages over CL, just by virtue of supporting more modern features (especially Clojure, which inherits all the features of the Java standard library).

That closing paragraph really is a fantastic one. It contains a Gibsonism that really resonated with me: "gloriously unsorted Global Ham Television Postcard Universes."

Even with all the order that we've consented to have imposed by various hubs over the past 17 years, it inspires a certain swell of optimism for me to consider that we've never really abandoned that spirit. The frontier may be long settled and built up, but YouTube, Tumblr, Imgur, and other gated communities still play host to the kind of spectacularly diverse, ham-radio aesthetic of 1996. And there are still frontier sites. Cult webcomics, improbable enthusiast projects, random artifacts of odd genius.

I hope we never lose this spirit, and given the past two decades of the web, I don't think we need to worry.

The Truth About Black Swans
No, you misunderstand. A global Java object (or whatever) in one process will be shared across all threads. If it has fields that get written "often" they are likely to end up thrashing the L1/L2 caches with snoop ejections. Often those writes are essentially spurious (global statistics, "current" thingy pointers) and don't really need to be shared across all threads. This really happens, and it's very easy to do.

An essentially identical architecture that defined the same object within a single address space is, quite clearly, not going to be subject to that bug.
... Because it is in the best (short and mid-term) interests of a debt-laden and debt-fuelled state to support those entities which can maximize further debt creation.

Banks do not exist in isolation. You could go as far as to say the problem is not so much Too Big to Fail, though that produces its own problems, as Too Interconnected to Fail. These issues have only become worse since 2008.

Alright, but you've carefully evaded the question. So let me ask you again: Would you acknowledge that Broder acted in bad faith if someone were to drive a Model S round trip between Milford and Groton at a reasonable speed, with the car in a freezer at 10F and without plugging in overnight?
I'm sorry, but as an actual member of this community, I find your objections a bit ridiculous. I, personally, keep everything I do on my local network, but I like it when people do these "Show HN" pieces.

It's almost as if you are personally paying out for the extra bandwidth this little project has caused for The Onion. This is not a commercial project, and most of the HN community is just messing around with tech to see how it works. Sometimes, people have the balls to show others, and I appreciate it. What I don't really care for is people who sign up and bitch about the derivative products of others on the basis of Intellectual Property.

My advice: Just ignore HN

P.S. I will help to compensate you for any personal financial hit you take.

Whenever I engage with BTC, "easy" is the last thing that I experience. Let's say that someone wants to start using bitcoin: it's as simple as downloading the software, double clicking on the icon, and... waiting 24hours or more for the block chain to sync, while the i/o volume on their disk goes through the roof.

Once you finally accomplish that, you can purchase some bitcoins, which involves... this: https://support.mtgox.com/entries/20490576-Withdrawals-and-D...

A few days later, you finally have BTC in your wallet, so it's time to start your bitcoin client again and use them. You double click on the icon and... wait 30min to 1hr for the block chain to sync.

Finally, you're ready to send them. Let's say you want to buy some music online, so you send BTC to an address that was generated by the site you're purchasing from and... wait 50 minutes to get enough verified transactions before they finally send you the music.

All of this would be completely impossible on a mobile device.

There are plenty of ideas for making bitcoin more usable, but they all unfortunately involve mitigating the strengths of the bitcoin as a concept.

> The Web is new, and our response to it has not yet hardened. That is a large part of its appeal. It is something half-formed, growing. Larval. It is not what it was six months ago; in another six months it will be something else again. It was not planned; it simply happened, is happening. It is happening the way cities happened. It is a city.

I've always loved metaphors comparing the Internet to a growing city. The Web used to be a Wild West-style town that was ventured into only by the most daring of people and businesses, but it's now become a much more established and secure city, still full of possibilities, where everyone and their mother wants to move and try to make their fortune, but at the same time has lost a lot of its original "flavor" that made it so special.

And... I don't really know where I'm going with this...
From the perspective of a complete server administrator novice, are all of the mainstream "hacks" due to the complexity of these applications? For example, if I were to setup a basic, updated Ubuntu Server LAMP stack with a MySQL database, is this system vulnerable? I understand how to protect against XSS and SQL injection and how to hash and salt passwords properly, but where can I begin to learn about implementing basic, hard server security? Additionally, how can I hope to secure my web app if corporations with entire security departments are failing to secure theirs?
> is there any real deterrent or risk for a company to use GPL code (in violation) first, and then fix it if/when they get found out and threatened legal action.

Well, there's a pretty wide gulf between "The Board of Directors and CEO decided that any legal consequences would be cheaper than not infringing" and "Oops, we didn't mean to mis-appropriate that IP".

The tricky area IMO is when a company or industry repeatedly "Oops"es and you have to start wondering whether they're even performing due diligence.

You are right Nick. We need to refine our message.

A blog with less structure, or cork-board can both be used to describe a subset of utility that we offer.

Since you are front end developer, you can potentially use it to share code snippets, for one (we do syntax highlighting). If you do design as well, you can put psd and ai files and get feedback from people on the page itself (you won't even need to download the files to view them).

Some people use Padlet for agile project management too.
Author here: Actually, the slide 'no publically available simulator implements this correctly' is somewhat misleading (it had a follow up slide that I cut and replaced by verbal comments - I should re-add it to the PDF). What I meant is that the entire mechanism (Task switching, page fault handling, etc.) is not implemented correctly on any sim, i.e. you have subtly different behavior. This was quite a challenge in debugging this in the first place, so I actually wrote the code to work around any bochs quirks I encountered -- just so that I have a debug environment.

The volatility of BTC is useful in such situations. If you sold now, the price may rise to $40, then crash to $15, and then rise again to new heights. So if you do sell (and are keen to stay in the long-game), you have to be confident that you will be able to buy in again at below that price (NB transaction costs). If you achieve that (which is done most effectively by guessing when the peak of the bubble occurs) then you wouldn't lose out it the long term. Then you have to weigh up the risk vs reward..
Maybe things are different in Europe, but if they installed street lamps like this in major urban areas in the US, someone would smash the glass within days.
Agreed, same situation here. Still, I don't believe the fictitional costs are the point where one should start fixing the system, not adding more beaurocracy. Insurance rates in Europe go up every year and the quality of service goes down. If the prices were really transparent, for everyone to see & upfront that would be a first step. Shame alone at such a criminal ripoff would make some doctors think twice - let alone trigger some good ideas how the system could be changed.

Tinfoil Security (https://www.tinfoilsecurity.com/) has automated scanners and seems to keep up to date with all the vulnerabilities quickly, like in case of the rails vulnerability recently.
Let me try to be more specific. If we consider the space of web development, I think you are implying that rails sweet spot is a small portion of that space. I feel strongly that a very large portion of the entire web dev space is within rails sweet spot. I think I can back this up, as I did once already with http://disney.com as an example.

"If you have high traffic it might make financial sense to forgo some productivity and choose a framework that can run on lower amounts of hardware"

My points about not using the deals and them being great offers was from the point of view of a customer.

"I don't think people should tip at all. Tipping is just a sneaky way of having the customers pay the labor costs directly. It's ridiculous to say a steak costs $7 when I'm paying the the server as well."

Not wanting to tip and actually not tipping are two different things.

I agree with you that the whole tipping concept can get ridiculous but like it or not, that's the system we have.

To not tip in all cases, in a system that has tipping as a critical part of the labor costs, is flat out wrong. You know the system is based on tipping and you're punishing the wrong person for your distaste for it.

If you don't want to tip, don't participate in the entire system. Don't go to any restaurants or other place of business that advocates tipping and makes it a critical part of the staffs salary.

Again, it's absolutely wrong to not participate in only one aspect of the system you dislike when the people who get hurt are the ones with little power to change things.

It's not a real subsidy. They're saying that by allowing banks to get too big to fail, the banks are in a sense using the assets of the federal government as if they owned them. Everyone knows the feds will bail them out, so they can borrow money more cheaply than they would be able to otherwise.
