You may be mistaken here, the day your bank disappear all your deposits and interests disappear with it. You probably this cannot happen which is what people believe until it happened to them, and this happened all around the world.

In Europe a 2013 law is now in effect which basically states no more bank bail-outs, from now on it will be bail-ins. In other words if a bank fails it will use its customer's deposits to cover its debt.

MongoDB will always be a relevant example of false advertising and over-marketing (to the point of 10gen probably opening themselves to litigation) and how we all need to stop drinking the kool-aid.

There is LITERALLY no reason to use MongoDB today. If you're thinking of using MongoDB, for the love of god just try PostgreSQL.
No, it is definitely fraud. The rule is that you may not enter an order (quote) that you have no intention of filling. You're perfectly entitled to change your mind afterwards (for whatever reason) and then cancel the order, but if you send an order with the initial objective of never having it execute, it is a fraudulent order and and a case of market manipulation.

Always hard to prove though, since it goes to the intention of the market participant.
Essentially you're proposing that BTC is used as'digital cash' rather than 'digital currency'. That's what Bitcoin is actually for - a cryptographically secure way of privately and anonymously transferring value between parties - rather than a fiat currency that has implicit value in itself that people can speculate on.
Not in the US. If a bank fails, the FDIC will insure each account for 200 or 400k (can't remember which).
You can do this in Oracle 12 and I think in Postgres. You might want to think about why you need to store unstructured data as part of your application though and query it. If it's expected to live a long time and be queried it should probably be structured. If not you could store it (a serialized object) as a blob if you are just caching some state.

That's exactly why I think it won't see more than marginal adoption.

The benefits of bitcoin are outweight by having to secure your private key(s) yourself.
Sure, but that takes a considerable amount of time and mental energy to set up and maintain. If possible, most people would just outsource the whole operation to some third party so that they can forget about it and get on with their lives. Of course, the third party would charge a fee for the convenience that they offers to their customers...

...and that's how you get a bank.

The issue would be that market makers would need to inject their orders (quotes) at a greater distance from the mid-price, in order to protect themselves against market movement during the minimum lifetime you propose. If my bid and offer is obligated to sit in the market for x seconds, then it is potentially a sitting duck for any adverse event during that time period, and I would have to quote wider to cover that possibility.

Bailing out bank and paying out deposits are two different things. Even in Europe your deposits are "protected" and will be paid out in the even that the bank can't. To a certain amount that is.
>...all your deposits and interests disappear with it

The US, EU and many other countries have deopsit insurance* schemes that limit risk to depositors. You may not get all your money back if you have large deposits, but for example in the EU you're generaly guaranteed to get at least the first 50,000 Euros.

In the case that bitcoin succeeds we shouldn't expect it to be a smooth ascend. After the dot-com bubble it too seemed like we had seen peak internet. A bunch of people underestimated how hard it is to do something useful with bitcoin, that doesn't necessarily mean that it will be a failure. I'm not confident that bitcoin will succeed, but neither am I confident that it won't.
Google Flight Search: One More Tally to Google’s Streak
So I can't find anything in the comments: what's the cause for this sudden crash?
I am living abroad and while I'm not truly poor, a couple of months ago I had less that £20 to my name, so I'm quite cost conscious.

I needed to send some money overseas and I looked at bitcoin for exactly the same reasons that you described. However, I found that sending the money via bit coin would take longer and wind up costing me more in transaction fees than just using transferwise. While the actual bitcoin transfer itself was free and instantaneous, there were multiple days of waiting and percentage fees to convert from or to fiat currency at each end of the transaction.
The answer that hasn't yet been mentioned in this thread: racism.
It's worse than that. To me, the biggest flaw of bitcoin is that you have to constantly spend energy on it (as in computation power / burn coal) for it to remain viable. As soon as enough people get tired of throwing away money at their miners someone can pull a 51% attack, so everyone must put more energy into their miners to protect their investment... forever.

Over time the amount of energy wasted by bitcoin could become stupendously dumb. We could be using our spare processor cycles to fold proteins or aid in numerous other research, and yet we're using it to allow people to send bits of data to each other without a need for centralized trust.

Compare that to the centralized bank where you have a single centralized trusted source which allows transferring money from one person to another to take no more energy than a modest server and some backups -- far less than the power consumption of a single GPU miner.

The above problem also won't get better. Even after you're no longer mining for new coins, you must keep up the mining volume to protect existing coins and allow transactions to occur at all. I personally find the above to be a fundamental problem with the "proof of work" solution. Sure, on paper you've solved the General's problem, but the reality is that you're throwing massive amounts of energy out the window. Because of that, I think this proof's place should have been to remain on paper.
Surely you're joking--Notch gave away the POC for free, and started charging for the beta somewhere before 2011 (when I started playing). Since then, new features and bug fixes have been essentially non-stop.

I picked it up after a long hiatus and found new terrain types, new monsters, new neutral creatures, an enchanting system, a brewing system, an entirely new dimension ("The End"), and several types of abandoned structures.
With bitcoin you don't get rid of the currency exchange rates you add another one. Source -> Bitcoin -> Destination.
It is not the transaction fees itself, but the currency exchange rates that kill you at one end or the other.

Wouldn't the incredibly volatile currency exchange rate of Bitcoin also cause problems? It is not immune to this as it is free floating against other currencies.

I'd love to see a world-currency which does away with existing credit card companies and transfer fees worldwide, but Bitcoin is not suitable, and I suspect if we see one emerge it will quickly be regulated and taxed by governments like all other means of storing wealth.
The Brood War API
You can do exactly the same thing with gold, i.e. holding it in different banks in different regulatory districts. If your friend's house is burgled or burned down. The one advantage of Bitcoin in this respect is that you can back it up in case of disk failure, house burning down, etc.
The predictable monetary supply of Bitcoin is precisely why it is doomed to fail. Specifically, Bitcoin's deflationary nature.

In the best case scenario, Bitcoin will continue to experience unstable boom-bust cycles as prices will rise when people start hoarding their coins, then crash again when people dump their Bitcoin en masse once prices hit a high enough peak. This is great for speculators, terrible for everyone else.

In the worst case scenario, Bitcoin prices drop to $0 when everyone gives up using it. Which leads to the second problem: Bitcoin never really solved the chicken-and-egg problem. Not enough merchants accept Bitcoin for customers to bother with yet another currency, and not enough customers use bitcoins for merchants to deal with yet another currency. Services like Coinbase are merely abstractions over the USD - too few merchants deal solely in Bitcoin, and for good reason.

Because this boom was the first time it was really in the publics eye. The previous ones happened when very few people had ever heard of bitcoin. This one happened when most people in the western world have heard of it. If they were going to get on board they would have done it but they didn't because for most people with money bitcoin offers very little upside over their existing systems with huge risk.
> Actually I find the problem of stashing gold very tricky.

This, and plus the fact that in almost every country on Earth now, buying Gold needs an ID of some sort so that governments know exactly where to look for Gold the day they want to seize it. I think one of the last places where you can buy Gold anonymously is Switzerland.

EDIT: and you have to trust that the Gold you buy is real. There's always the risk it's gold plated tungsten or something.

"I don't want to create a schema..."

You are always going to end up creating a schema, whether it's explicit in your tables or implicit within your code. Otherwise you end up with completely heterogeneous data which is impossible to query in any useful way.

This is a red herring.
>So they really were genuine offers to sell and buy shares.

They weren't genuine, that's the point. They were offers made with the express intention and hope that they never get filled.

The orders from high frequency traders in contrast are honest orders, when they are sent they honestly express that the trader wants to trade at that price. The fact that they may then be withdrawn 800 microseconds later when the HFT recalculates its price in response to some stimuli and changes its mind about the price, doesn't change the fact they were honest. They're just fast as well. That's what control systems do, they update their outputs when their inputs change.

That's different than using Shamir's Secret Sharing [1] to split the private key/seed across multiple safe deposit boxes.

If one safe deposit box full of gold is stolen, that portion of the gold is gone. If a safe deposit box containing 1/5th of a Shamir's Secret Sharing secret is stolen, the secret can't be reconstructed by the thief, but can be reconstructed by the owner if they still have access to 3 of the 5 pieces (for example).

>>All negative externalities are coercion, because people are forced to bear costs to which they do not consent.

I think it's a bit of a stretch to extend definition of coercion to such situations (social dilemmas). The costs other people bear often aren't direct and parties in the transaction often don't realize they impose those on others.

I don't believe that sentences: "Any voluntarily transaction between two actors in the system produces net gain in the system" and "Any voluntarily not coerced transaction between two actors in the system produces net gain" are equivalent. At least it's not immediately clear.

Anyway, if that is what you mean then I am sorry for tone of my comment. I am just allergic to libertarian anti-intellectual assertions about transactions and free choice and maybe I'vce read too much into the way your sentence was formulated.
Huh? Usually it works the other way around. If you increase demand by buying a significant portion of Bitcoins, you INCREASE the price. And if you then don't sell that significant portion, you decrease the supply, which again INCREASES the price.

For example, in the stock market, if there are rumours of hostile take over, the price of the particular stock rises. Think about e.g. Yahoo/Microsoft acquisition rumours.

Roguelikes are defined by permadeath, quick runs and procedural generation.

Diablo 2 and Torchlight have the latter, but they are quite old, and the resurgence of roguelikes is relatively recent.

I believe it's just has to do with it being a very solid (and addictive) gameplay model, and one that fits much better indie games than AAA titles.

From what I can tell, it looks a lot like the oil price collapse. Not that it's directly connected, because BTC holdings are still very low and not really part of any serious investor's portfolio.

But it looks like a lot of people have invested in extraction capacity, and they need to sell to remove their BTC risk. They're buying the mining equipment in dollars after all. And they know that faster and faster chips will come on the market.

On the other side of the equation, demand doesn't seem to have increased quite as much as expected. You still have to go out of your way to find something that you can buy with BTC. Heck, I have a few BTC and I've never used them for anything, and never come across a vendor of something I wanted who wanted BTC for the item. In fact, there are only three categories of people I've met who were interested: nerds, people who wanted drugs, and people who wanted to launder money.
There is a "cost per transaction" in bitcoin as well: https://blockchain.info/charts/cost-per-transaction

It costs a certain (very high!) amount of real electricity to process a block. This plus an incentive has to be paid to miners. Miners have to pay for their electricity in real local currency. Therefore for every transaction block processed either someone "buys in" ~$10 worth of bitcoin or the outstanding value of all bitcoin drops by that amount.

You buy shares in GLD ETF which holds physical gold for you. The risk is that SPDR collapses or get their assets stolen.

You can also buy gold futures on the futures/commodity exchange which is a contract that specifies the other party has to deliver gold to you in the future. The risk is that the financial system collapses and the broker/clearing broker cannot uphold the contract anymore.

So it depends on your intention for buying gold, if it's to hedge against inflation or market crashes, buy a gold tracking security will be fine. If it's to be used as a doomsday currency, then I think you're better off hoarding canned tuna, vodka and guns; things that you can either barter with, or use to force other human beings to do your wish.

I've used it and been happy. If you want something that's simple to use, know your schema partly but not entirely, and you don't mind losing a few writes, then mongo fits.

Relational databases place such emphasis on reliability. Mongo is generally reliable but only two or three nines, and it's simple.

For example, if you're collecting sub-cent line items for invoices, you might prefer to collect 99.x% of the line items simply over 100% at greater complication and expense, particularly if you can measure x.
Ok, I don't have this option, transferring between my own accounts is easy (requires a pin code) but transferring to someone else's account requires a separate device + your pinpas + your pincode + scanning the screen with this device + typing a generated code into the computer/smartphone.

It would be more stable with more wide spread adoption, I'd guess if shops were to use it they'd en masse refuse to fluctuate/change prices every day, dampening the trade induced fluctuations.
