The bitcoin wallet is stored at ~/Library/Application Support/Bitcoin/. All versions look to the same user directory location for your wallet.

Yet I did a search and couldn't find bitcoin anywhere on my comp. Also why did it disappear from my desktop?
205  Bitcoin / Bitcoin Technical Support / Re: Forced to upgrade to 5.1 - Can someone explain why? on: January 09, 2012, 04:34:36 AM
maybe the mac client stores the wallet in a place that doesn't disappear upon deletion? keychain comes to mind for me.

i'm not a mac expert, so i'm not 100% sure Tongue

Never deleted the wallet or the client.
206  Bitcoin / Bitcoin Technical Support / Forced to upgrade to 5.1 - Can someone explain why? on: January 09, 2012, 03:33:26 AM
Using a mac here. Yesterday my bitcoin application logo had a question mark superimposed on it. Clicking on it did nothing. I searched my computer for any application or file containing the word "bitcoin." I thought my bitcoins were lost.

I later downloaded the latest version of the app - 5.1. Upon opening the client for the first time, the bitcoins from my old client appeared.

All's well in the end, but can someone explain how this occurred? How did my old client just disappear? And how did my coins re-appear in the new client?

Didn't see a poll, and was interested.
208  Economy / Goods / FS: Nearly Complete Set of THE OBECTIVIST (by Ayn Rand, Nathaniel Branden, etc) on: January 03, 2012, 11:14:04 PM
Formerly The Objectivist Newsletter, The Objectivist was issued monthly from January of 1966 to September of 1971. This is nearly a complete set. Of the 69 issues of The Objectivist, this set is only missing 1 (Sep 1971). You can periodically find a replacement on eBay. Writers include Ayn Rand (or course), Nathaniel Branden, and Leonard Peikoff. Asking 40 BTC. You could pick up in NYC (preferred) or I can mail.

These completely original soft-cover mailings have been put into a custom hard-cover binding, but the originals are still removable.



209  Bitcoin / Bitcoin Discussion / Re: Increases in bitcoin prices are bad for merchants on: January 03, 2012, 08:25:15 PM
Personally, I spend more bitcoins when the price goes up. Since I bought low, I feel I am getting more value for my money.
210  Economy / Speculation / Re: A way to buy bitcoins by credit card or paypal? on: December 30, 2011, 01:52:41 AM
eBay is probably the easiest, but there's a bit of a premium.
211  Other / Beginners & Help / Re: Had a dream about BTC prices... on: December 11, 2011, 05:42:54 PM
Like the Mt. Gox crash in reverse?
212  Economy / Speculation / Re: Can someone explain the price difference between Tradehill and MtGox? on: November 20, 2011, 05:44:33 PM
There's a discrepancy because it's two different sets of traders. Because people like you are aware of the difference in price, and want to profit from that difference, you'll try, and doing so draws the prices together like a magnet. Let's say you do buy on Mt. Gox for $0.20 cheaper and xfer to TH to sell. First, you'd need enough volume to make the fees from BitInstant and TH justifiable. You also risk the TH price dropping while your BTCs are in transit. You sell your coins, which pulls the price closer to the Mt. Gox price if you aren't able to find buyers for all your BTCs.
213  Other / Politics & Society / Re: So, I looked up what Rand had to say about humility... on: November 11, 2011, 03:25:44 PM
I think humility is valid in the sense that you are always subservient to reason and evidence. If you make a claim which later turns out to be false, then humility may allow you to admit that you were wrong and embrace the truth.

In other words, I think humility is about loyalty to the message of philosophy, rather than the messenger. A philosopher without humility can never change their viewpoint even in the light of new evidence in support of a contrary viewpoint. A philosopher with humility with always look at everything from first principles, and change his mind when appropriate.

Does that make sense?
214  Economy / Marketplace / Re: Is There Any PROOF the FBI was Contacted in Relation to Mybitcoin.com? on: August 31, 2011, 12:27:00 AM
I got exactly what I expected from a government organization to which I have donated hundreds of dollars to involuntarily - that is, nothing.
215  Economy / Marketplace / Re: Is There Any PROOF the FBI was Contacted in Relation to Mybitcoin.com? on: August 31, 2011, 12:10:32 AM
This is very interesting. Is there anyone here that contacted the FBI about MyBitCoin? I never used MyBitCoin in the first place, but watched the entire drama unfold. It just never felt right, but then again I'm an overcautious person.

I filed a report with the FBI. It was only 70 bitcoins, but I figure the more people who file, the better the chance there is they will do something - still unlikely

217  Bitcoin / Bitcoin Discussion / Re: Bitcoin = Communism? on: August 25, 2011, 10:30:58 PM
Random thought...

Bob might be working his ass off to improve bitcoin, which in turn raises the price of bitcoin. But Joe sits back and enjoys the fruits of Bob's labor by simple holding on to a bunch of bitcoins he did almost no work to acquire.

If Bob minds his own business, then we don't really have a problem. But if Bob wants to maximize his returns for the work he puts in...


...then he can buy bitcoin, sit back and relax, just as Joe did. This further increases the price, stabilizes the market, and gives more incentive for others to improve bitcoin.

In communism, property is publicly owned and controlled. In bitcoin land, private parties own and hold bitcoin. Those private parties chose when to buy, and when to sell. If bitcoin was communism, then there would be some type of central entity - call it a "central bank" which controls the supply of the money and distributes it to those who need it most, from those who produce. So I'd chime in about now that our current Federal Reserve system is more communist than BTC can ever be.
218  Economy / Speculation / Re: Monday after Conference rally fizzles on: August 22, 2011, 07:07:35 PM
There were so many positive aspects about the conference, I'm surprised we didn't see a bigger rally. But yes, the price has done a short-term peak around 11.5, methinks. We'll see.

I've really got to stop watching the charts. I'm pretty sure I can ignore bitcoin completely for a year or so, then fire up my client, take a look at the price, and be quite happy.
219  Economy / Services / Re: MadGenius.com, a great webhost offering 30% for the Bitcoin Community on: August 18, 2011, 08:26:00 PM
I was in the market to buy a domain name, so I took you suggestion and went to this site. I was disappointed to find that:

A. The 30% discount does not apply to domain name registration.
B. They is no option to pay in bitcoin!
220  Bitcoin / Development & Technical Discussion / Re: Could the Power of the Bitcoin Miner Network be Used Elsewhere? on: August 17, 2011, 02:30:54 AM
The mining is not arbitrary waste-of-time kind of work.  It serves the purpose of securing the network, and cannot just be replaced with other activities.  The biggest weakness of Bitcoin is if any one entity, or group of cooperating entities control more than 50% of the entire global computation on the BTC network.  This is because, in order to execute a double-spend, you have to be able to write blocks faster than the non-cooperating nodes.  In this sense, when we talk about "difficulty", it's not just difficulty in generating coins, it's also difficulty in attacking the network.  

If a bunch of miners were to switch to some other problem, even temporarily, that would open the door for someone with a lot of resources to take a shot at double-spends, which could do quite a bit of damage to people's overall confidence in BTC.  I'd say that no one has the resources to do this at this point, but you mentioned governments, which are probably the only entities left with "feasible" resources to do it.   So the best way to defend against the attackers/governments is actually to do exactly what we're doing already, which is mining as fast as we can to max out the difficulty.

Now, the question has come up before, is there any other kind of computation that could serve the same purpose as hashing for the BTC network, but also be useful in some other application?  There's two criteria for this:

  • (1) The "problems" to be solved must have flexibility to impose arbitrary difficulty of solving -- so that the network difficulty can be calibrated to the global computation speed
  • (2) A solution to the problem in (1) must be extremely fast to verify.

Hashing to a set number of zeros is great because the target hash can impose just about any level of difficulty on the network, and while it takes 2^52 hashes for you to find a block with 52 zero bits in front, it takes everyone else exactly one hash to verify you found a solution.  This is why it's called a "proof-of-work" security.  It requires a ton of computing power to produce a valid solution, and easy to "prove" that you did it.   If you can find another problem that has this kind of flexibility and solve/verify relationship, it might be possible to use it.  But it would most definitely be in another blockchain... and lord knows we have enough of those already...


I really appreciate your detailed response. I know that the work of the miners is not for naught - it provides the essential and elegant solution to network security - I was just wondering if the power could ever be re-directed to some other purpose. Thanks again.
