Nothing prevents you from moving bitcoins between exchanges, but moving dollars between exchanges turns out to be much more difficult than you might expect. Banks and governments introduce all sorts of roadblocks, charges, and delays. In order to arbitrage effectively, you need to be able to transfer dollars as well as bitcoins.

I'm a backer of Chris Robert's Star Citizen. The big appeal for crowdfunding for both Chris and all of us supporting him and the team at CIG is that he gets to make the game he wants, we trust Chris to make a great game, and anything that cuts the Bobby Koticks out of the loop is GREAT!
No, it can't - the limit is just over one million rows. This doesn't involve pulling anywhere near that many rows into your spreadsheet.
Yes, it does. This doesn't involve pulling all of your data into a spreadsheet.
Other currencies are fractionally devalued, because the total money supply in the world (across all currencies, including Bitcoin) has increased, and because money is just a demand on all non-money products and services. More money demanded against the same amount of global products and services==devalued money.

Other currencies are proportionally less useful and demanded and bitcoin becomes proportionally more useful and demanded.

Minor nitpick:

> Wealth can't be created

Yes, it can. Since money is just a demand on all other kinds of value, printing money or creating a new currency redistributes the ability to claim those other values. But if you actually create those other values---e.g., if you invent a Cyclotron or Google or are the next Bill Gates or you grow fruit or catch fish or cut hair---wealth is being created.

EDIT: I should be clear that I think that wealth redistribution via creating a new currency is completely just and proper. It is an implicit reward for creating a better way to trade, and it can only be obtained if you actually do create a better way to trade (and this is what Bitcoin speculators are, hopefully, doing). Wealth redistribution by printing money (a la the Fed) is evil.
What's odd about that?

That was likely the fear at the time, but what we actually saw was Javascript became popular because it was useful and there wasn't really anything else like it. It became popular, so Microsoft threw in with it too.

In order for that to have not happened, it would have had to be so unpopular that Microsoft would decide it wasn't worth adopting, but still popular enough to get Microsoft on board with the general idea. I just don't think that is likely; people would have sucked up a scheme-based javascript even if it was a tad unfamiliar; it was that useful.

(Not to mention, going with the cynical "three E's" theory of 90s Microsoft, they would have at least first adopted it before perverting it.)

I think people overplay the importance of being C-like. AutoLISP hit a bit earlier and found a very strong following in a non-programmer niche. People doing web development were already fucking around in HTML of course, so clearly they could wrap their heads around things over than curly braces.

Thanks for mentioning my "Ask HN". Your site hit the nail on the head for me.

We software developers get good pay, we're not going hungry. Challenges are important, but it's not too hard to find that if you look.

It's worth looking for a job that makes you feel good as you do your work.
Meh. In the UK this line is non-existant. To be a freelancer you set yourself up as a company (it's the most tax efficient way) so exactly whether you position yourself as a body for hire or a solutions company is up to you.

If you want to be a solutions company then be prepared to be a salesperson as well as engineer. If you want to be a body for hire then there are hundreds of agencies that will do that part for you.

They're all assholes, but that's their job.
This is common, but Virtual Desktop Infrastructure is increasingly common currently. The only novel thing about Amazon's program is that the server is in EC2 instead of the corporate server closet.

As I understand it, some of the motivators are:

1) The image is immutable (by normal users). Each startup is clean, so the potential to screw up your install is very low. Only user folders (redirected to network storage via GPO) persist.

2) You can indeed use thin clients, i.e. http://www.neweggbusiness.com/Product/Product.aspx?gclid=CIT... with VDI. You can also use old/underpowered/very cheap PCs.

3) Unlike an RDP setup, each user has their own OS instance so you don't have concurrency issues.

4) Windows Server and User/Device CALs are indeed very expensive. However, license costs for the clients are not even slightly relevant because mainstream desktop/laptop hardware comes with mandatory OEM licensing anyway and large businesses are not typically building their own PCs.
I have a ZTE Open as well. Did they release 1.1 for it? I thought they didn't.
Of course not! I am suggesting that connections should be encrypted by default, whether the endpoints can be authenticated or not.
For 2, I think it was overly ambitious to think that within a program family so small it has only 88 members there would be one ideal hash function. And If you compare the simplicity of Damgard's design to the contortions that modern hash designs employ to stymy cryptanalysis, it's hard to think that more designs constructions wouldn't perform better, even on that particular automaton.

For 3, I think having a full 7 slides of Bertoni et al's slide deck devoted to the influence of CA-based cryptography on SHA-3 makes it fair to call the approach influential.

Thanks for the references!
When M:N threads are truly baked in (either at the runtime level or the OS) blocking an M thread doesn't block the underlying N thread.

An example would be Erlang which is a runtime built from the ground up to support lightweight threads where reading or writing to a socket of using the built in APIs won't block the underlying OS thread. You can still sabotage the runtime by writing your own native library and doing blocking operations from there, but the pitfalls are more obvious in that scenario.

If the underlying concurrency and network/disk IO primitives are truly non-blocking for lightweight threads then everything built on top of them will also be non-blocking. Non-blocking for the underlying OS thread that is.

That is where co-routines and other co-routine like libraries are a leaky abstraction. If you step into one of those blocking APIs in a third party or standard library you will block the underlying OS thread. This means you can't integrate with existing code or tools easily and you are always vulnerable to accidentally doing so.
We'll certainly keep an open mind and think about offering other OS's in the future. Like every AWS offering, we launch an MVP and then iterate rapidly.
Why would I give up fixed operational expense of distributing my game and instead pay Amazon computing resources everytime one of my users played? The more you use, the more you pay. The more users you have, the more revenue you will need to cover the cost of the computing resources needed to run the game for your players.

Not to mention if you ever need to get off of Appstream there is no migration path, because you used their SDK to build your game.

So there is a high level of lock-in, and its introducing a cost structure that is coupled to the usage of the app. If using Appstream helps your apps be more successful, then it also helps you give more of your profit margin to Amazon.
That reads like (s)he was sitting at the computer with the intention to sell at $350, and happened to be there to see it quickly drop to $275, got nervous and cashed out. The unlucky was that (s)he never would have thought to sell it except for seeing the price crash in real time.
This seems like it exists just because it can. It basically does 2 things:

1. Fat % of a area/muscle group

2. Muscle "quality"

To address each:

1. One of the most accepted truths in health is that you can't spot reduce fat. There's no point in determining the fat % in a part of the body instead of overall since you can't just reduce the fat in one area. You can only reduce your TOTAL body fat.

2. I'm not sure how muscle quality is any better than just knowing how much weight you can lift. For example, if you really want to know the "quality" of your biceps, just track and measure how much you can curl. Of course everyone who lifts already does this.
Disclaimer: I work on fanout.io, so there's that. ;)

What's nice about fanout.io is that it makes APIs like HNStream easy to build and scale, while remaining invisible to clients. One cannot use firebase to create a custom realtime HTTP API like has been done here.

Firebase does have other features like data storage, though. IMO the two services serve different purposes.
"It's based on how much money the company's expected to make over its lifetime." - So guess work right. Because a company that isn't generating revenue yet without a model yet is nothing more than speculation. Like you cannot reliably predict the stock market based on historical data alone.

What this all means is that companies like Snapchat are all hype geared mainly for the ones with vested interest to get a quick cash out. There is nothing "lifetime". Kinda like the stock market where you see volume (demand) move thinking that supply will drop and price will go up so you make stupid decisions to jump in.

As for Facebook, maybe Snapchat is worth that much to them. To Facebook it would increase their users engagement and spin the marketing engine. For the public market Snapchat is an over valued company based on speculation, hype and fueled by those with vested interests. There really is nothing stopping competitors from entering this space. There is no IP in timed photo sharing. Unless I missed something?

I went through that same thing -- managed to schlock through a mortgage just as a contract was ending and I was going back to school. I've never missed a payment or given the lender any reason to regret lending me the money - but had I applied a month later, they would have turned me down.

I realize now that an elegant way to handle this type of situation is through an LLC where my annual income is a separate fact from the on-and-off-again nature of contract tech work.

You misspelled "insanely inflating". At least BTC is deflationary, albeit unstably.

If you're irresponsible (weak passwords, no backups, leaving things decrypted, using Windows... hehe), sure. If you keep your money at somewhere like Coinbase (where they keep 90% of their funds offline in cold storage) and use 2 factor authentication, very unlikely.
Hey, I remember first hearing about them on 4Chan /g/ back in late 2011, when they were maybe $6 a pop. We used to call them "Buttcoins" and laugh at all of the people mining them.

Cool point and I agree.

The sample has to represent the population, that's fundamental. If the sample is so small that it can't characterise the population distribution, then you have a problem anyway. If you're measuring a events that happen 1% of the time (or 99% of the time), a sample of 100 is not nearly enough.

If you chose an appropriate non-parametric test to cover an unknown distribution with a small sample, it maybe would have zero power (impossible to give a significant result)
What the f--k is a "corporate baseline"? If it's some sort of pre-done corporatized software stack using some nonsense like IBM Tivoli ("provides Integrated Service Management software to help manage business value of your IT infrastructure" -- sounds like something generated by http://cbsg.sourceforge.net/cgi-bin/live), that's where most of your problems lie. These are a pain in the ass for everyone -- people who have to use them and people who have to support them.

Trust your users. If you can't, educate them. If you still can't, get rid of them and hire smart people you can trust. Now you don't need fancy "desktop management".
0.83 / hour sounds really expensive
Some of our internal corporate apps require IE9 as IE10 presents compatibility issues. I'm not at all surprised that it IE9 is part of the baseline.
I'm not saying this isn't a fair price given the technological constraints, but that basically means we're going back to the pay per hour model of gaming, a la AOL. That's going to be an expensive game.
“I happen to think that most of it is written in simple, straightforward, unpretentious language”

Hahahaha. That’s the funniest thing I’ve read someone write about Wolfram.

The comparison to Darwin is also pretty amusing. Darwin’s book is amazing because it spends most of its effort showing us evidence, so we can draw our own conclusions guided by an overwhelming pile of careful data and research, plus a bit of sharp analysis. By contrast, Wolfram’s book spends most of its effort telling us how important it (and he) is, on unremarkable and tediously repetitive evidence/analysis.

edit: note the Oxford American Dictionary’s definition of pretentious: “attempting to impress by affecting greater importance, talent, culture, etc., than is actually possessed”.

For example count the number of things named “Wolfram” in this most recent blog post, or count the hyperbolic adjectives and adverbs: “amazing”, “whole different level”, “profoundly important”, “incredibly useful”, “breathtaking”, “exciting”, “spectacular”, “sophisticated”, “universally accessible”, “new kind of language”, “cover[ing] all forms of computation”, “by far the largest ever”, “immense”, “spectacularly productive”, “remarkable”, “immense”, “completely general and uniform”, “immense”, can’t-do-it-justice, “immediately meaningful”, “absolutely practical, and spectacular”, “amazing”, “never imagined before”, “incredibly fertile”, “disorienting”, uniquely converging, “universal”, incredibly powerful, “instant”, “absurdly”, “seamless”, “dauntingly long”, “widely accessible”, “wonderful”, “exciting”, “with full semantic fidelity”, “instantly programmable”, “a kind of global brain”, “convenient”, “efficient”, “a new level of computation”, “our most important technology project yet”, “incredibly exciting”.

If you took out all the adjectives, and all the instances of “Wolfram”, there’d be pretty much nothing left. ;) [NKS is thankfully not quite this bad on a sentence-by-sentence level. But then it has 1000 pages to repeatedly tell us how revolutionary and brilliant it is.]

> regretting having sold bictoins earlier because of some feeling

They turned a risky as hell deflationary asset into a low-risk slowly-inflating one :)

Hindsight is 20/20. At any time, Bitcoin could experience... a problem. Which affects its value, badly. By selling, you simply dodged the cost of that risk, which is real.

There will be Senate hearings soon on Bitcoin. The guidance coming out of this alone could boost the value even further... or slam it.

http://www.economicpolicyjournal.com/2013/11/bitcoin-senate-...

And if it slams it, you should buy, as Bitcoin is a global phenomenon and is incapable of being controlled by the US Government no matter how they propose to deal with it. :) Germany and China are already quite positive on it.
This makes me wonder what social network analysis for VCs and start ups would look like. It sounds like this model ensures that the well-connected founders get funded despite the merits of their ideas & implementation efforts.
One advice: ALWAYS use a Limit order with bitcoins. Both limit buy orders and limit sell orders. That way you're guaranteerd to buy/sell for the specified price instead of the next best offer.
Thanks for the reply - that's helpful! I have an Ivy bachelor degree in a science field, it's in an expensive area, and I'm a core developer for a popular open source project...didn't think about it how you phrased it.

I know Python very well (to the point where I seemed to be at or above the level of the devs I talked to), and I've dabbled aside from that.
I see you've got green energy and medical technology jobs there. Why not jobs where you can commit to open source projects? Now _that's_ what I can a "job with meaning".
Funds in BTC can't be kept 'offline', if you know the private key you can spend the coins.
Definitely. Your idea would be awesome though, just it a lot more obstacles to get through to produce it.
If you're thinking about trading bitcoin, I would suggest you don't use MtGox. It has problems with withdrawals of USD, and hence has an inflated bitcoin price compared to other exchanges [1]. Once your money is in there, the only fast way to get your money out is to withdraw bitcoin, hence the disparity.

Why can't wealth be created? Value (of which wealth is a store) is entirely subjective, and is not at all a zero-sum game.

If John Lennon wrote a poem on a sheet of paper just before he died, that paper would now be worth a vast amount of money. Considerably more than the 1c value of the sheet of paper alone. Nobody had to pay anything to create that poem.

Bitcoins are currently valuable, precisely because (and frankly, only because) people put a value on them. That means that if I'm willing to spend $400 on a Bitcoin, and someone is willing to give one to me at that price, that is how much it's worth.

That single transaction may be zero-sum, in dollar terms, but next week I might sell the same Bitcoin for $500 or $300 in another (dollar-terms) zero-sum transaction. The Bitcoin is the same. The price (value) is all that's changed. Just like the price of the sheet of paper containing John Lennon's last poem after he wrote on it.
