What if I could double-spend just my losing bets?  That would cost them plenty.

Yup, I guess I should have qualified my statement by saying payouts for wagers that end up being double spends don't cause a loss to SatoshiDICE.

We know that to do that type of double spend (using the Finney attack) is expensive. And a mitigation should SatoshiDICE start to see these occur, is to delay disclosing WIN/LOSS status long enough so that a financial loss is ensured for anyone attempting this strategy.

has there been any larger test cases for a mesh net ?

Yes, and there is an org that is doing testing of a wireless mesh WAN, although I can't think of the name just now.  I believe they are working in Arizona right now, but they already have a nationally allocated frequency band license from the FCC, so this is no fly by night operation.

Sounds like Free Network Foundation.   They have a nationwide license for 3.6 GHz  (for backhaul of a Kilometer-wide range).
They are operating a mesh in Kansas City right now.

2724  Other / Beginners & Help / Re: Transaction change vanished on: December 02, 2012, 04:40:37 AM
The history of transactions (all of them from now unknown addresses since this backup was so old) came up, but towards the end the same problem with the -1BTC followed by the -99BTC came in. And after that the latest transaction of -99BTC this time displaying also the corresponding change of -1BTC!  So, the problem was repeted, and the account is now empty. [/quote

Now I'm confused.  You said the 99 went in transaction 724d1caf9cc4302d02564908fcbd1d47878732b6eb4da818a3495709d595944c:

So from that transaction I see that the 1 BTC went to 1NNdZiBH3yLsBSxrdVrJRptaj99hQwvbKy:
 - http://blockchain.info/address/1NNdZiBH3yLsBSxrdVrJRptaj99hQwvbKy

But that 1.0 BTC amount hasn't been spent since that transaction.  And that address later had another 99 BTC sent to it, so it now holds 100 BTC.

Have you tried launching the Bitcoin-Qt from the command line with -rescan?

2725  Bitcoin / Mining speculation / Re: Reward Half without ASICs = Bad for miners? on: December 02, 2012, 04:04:49 AM
Are you one of those?

Heh, nope.

Also, how long do you think GPU miners with free electric will keep mining, even AFTER the ASICs hit?

If the GPUs are providing needed heat for the winter, maybe springtime.  Or earlier, especially with the noise.

Just like nobody messes with CPU mining anymore, once 100+ Thash of new capacity comes online, those GPUs won't be doing any good even with free electricity.

Now there could be continued life with CoinLab's HPC effort ... especially for those with a low cost of electricity.

Shut the site down ASAP!
And Fix this ASAP,
before the hole is dug too deep.

LOL.

Just in case anyone else is unaware of how SatoshiDICE works, the payouts include coin from the original wager.  This is the innovation that allowed them to do instant payouts without having to wait for confirmations.  From another thread:

Incidentally, wagers that are double spends don't cost SatoshiDICE a thing, because even if they sent a payout for the WIN already the payout will not confirm either as it too will be a double spend.  And it is then no different from having never made a payout at all.

When these situations happen with SatoshiDICE, they can take a day or two to resolve.

There's nothing you can do but wait.

lightlord,

you will get your $717.88 in 72 hours.

I will even bet 18.572 bitcoins. If accept and get your $717, you send me 18.572 btc. If not, I give you my entire wallet in 72hrs.

The countdown starts when you accept.

Heh.   Don't do it. lightlord or at least ask for like 100:1 odds.

[Edit:  TradeFortress ... at least make it look somehow fair.  "If not, I give you my entire wallet in 72hrs."]

I just hope they didn't lost too much, to declare bankruptcy and forfeit everyone winning payments.
I notice they are doing all the little payments.

FFS, Would you just relax.

This is not the first time this happened.  Every transaction on SatoshiDICE that is a WIN eventually gets paid.    This is provable using the blockchain.

Your transaction confirmed.  It shows WIN.  You will get paid, just not right now apparently for whatever reason.

2729  Other / Beginners & Help / Re: Mining on a laptop? on: December 02, 2012, 03:16:27 AM
My question is- Does it make sense mining on this laptop?

Even when GPU mining was profitable this was not recommended because it is so easy to harm either the GPU or the laptop with mining with this form factor.

After halving occurred a few days ago, unless you pay less than about half the average rate for electricity you are not going to be able to mine for profit on a GPU.  

The average electric rate is $0.15 per kWh, so if your cost of electricity is 0.075 per kWh or more, mining on a GPU now (and going forward, most likely) is a money-losing proposition.
2730  Other / Beginners & Help / Re: buy linden dollars without second life? on: December 02, 2012, 03:06:25 AM
6.5 year veteran of Second Life here.  I don't see how it would be possible to do this.  Linden Dollar balances only exist on the Second Life servers, tied to an account name.  Even Virwox itself and the Second Life company account (named "Supply Linden") have account names.  To have an account name, you must open an account on Second Life.

A.) If you are transferring Linden dollars from someone else, then yes -- you must register an avatar to receive them before you can send them to VirWoX to convert to BTCs.

B.) If you already have Second Life account and just want to sell your SLLs through VirWoX, then you update your VirWoX account with your avatar id, and then use the VirWox terminal in-game to transfer the SLLs to VirWoX.

C.) If instead you are first buying SLLs from VirWox and only using them to buy bitcoins, then it is all handled within VirWoX's ledger.  i.e., SLLs never left VirWox's account.  It is just a book entry.  And thus you don't need to touch Second Life or register an avatar.

I'm not trying to sound like a jerk,

And the first couple of times you expressed your concern, you didn't.

There seem to be extended delays at SatoshiDICE.com right now, from looking at their site:
 - http://satoshidice.com/lookup.php?tx=&limit=1000&status=ALL

If you are hoping for fast payouts, you might want to not make any new wagers until SatoshiDICE staff gets things resolved.
2732  Economy / Gambling / Re: SatoshiDICE.com - The World's Most Popular Bitcoin Game on: December 02, 2012, 02:28:45 AM

Isn't the reason we put money in the bank is for the safety and security of our funds?

Exactly, and that's why I think the banks should do their absolute best to secure said funds. And if they don't they should rightfully be punished.

Does a bitcoin exchange have that same level of responsibility?

2735  Other / Beginners & Help / Re: Well, Hi There! on: December 01, 2012, 10:49:10 PM
I have a few labs of computers at my school at my disposal for mining,

You are allowed to use those for the purpose of converting the school's electricity into bitcoins for personal financial gain?   Have you gotten permission (in writing, to be safe).

As far as whether or not it is worth it even if you get permission is another topic.

Are you aware of the performance levels the ASIC mining hardware is being promised to deliver?
2736  Bitcoin / Mining / Re: Three days out, and network hashrate unaffected? on: December 01, 2012, 10:45:50 PM
Do we need a poll?  Are you:
A Still mining

Baffling, isn't it?

I'm suspecting inertia.  When the next power bill comes in and the bitcoins earned don't cover it there'll be some GPUs going dark.
2737  Bitcoin / Mining speculation / Re: Reward Half without ASICs = Bad for miners? on: December 01, 2012, 10:44:04 PM
So this is more of a question to those people who WANTED the ASICs to be delayed to extract more from their GPU rigs: Do you still feel the same way?

Here's who is happy right now.

Has investment in GPU rigs, pays about half or less of the average eletric rate (average is $0.15 per kWh so pays $.075 or less), is not likely to be among the first ones to receive an ASIC.

The longer this drags on at current BTC/USD and difficulty levels, the longer those GPUs will remain profitable.

As soon as ASICs ship, even those remaining mining on GPUs will find that the GPUs are no longer useful.

The bank should of course pay up on cases like these. Also, you can't expect all businesses to be experts at information security,

Anyone storing $3K nonetheless $300K should be well aware of two factor authentication.
2739  Economy / Services / Re: Coinbase - Solid or not? on: December 01, 2012, 09:31:50 PM
Do they require me to give withdraw access to my bank account?
Or can I just allow them deposit only?

To use Coinbase for buying or selling coins you would link a bank account, just like you would with PayPal or Dwolla.  That link allows Coinbase to push funds to you as well as pull from you.  They do not provide a method to link for only pushing funds to your account.

They are a startup that has a lot investment backing (as far as bitcoin startups go).

Not that this will help anyone find who did it, but just to let you know that I got no help from paypal even though I sold the bitcoins with a tangible item and a delivery confirmation number

I'm just curious about the details here.  So the recipient had to redeem the funds?  (.e.g, Mt. Gox redeemable code, or private key, or Instawallet URL) that was delivered, or did you send the coins some other method?
