1781  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] profit switching auto-exchanging pool - middlecoin.com on: December 11, 2013, 11:52:29 AM
Lost a whole lotta money for ignoring this subforum. Was pointed toward here the other day. I've been thinking about GPU mining altcoins for the free heat (recently switched to electric heating, anyway), but didn't want to deal with all the hassle of keeping up with the 100+ different Bitcoin mutations and converting them into BTC. The 3% fee is really pretty generous considering how much time I'd be out otherwise just to have one card running, so even if OP's doing some extra skimmin', the payout's still pretty good, transparency be damned.  Smiley

ETA: Now I just need to build some mini-boxes to put around the house where the electric heaters are now and I'm all freakin' set! Once it warms up, just move 'em to the horse barn!

Ok so obviously I will create another wallet. But how long will it take for the BTC number to display on the Middlecoin website? Do I have to mine a certain time, amount?
No clue on that (maybe when your first share is accepted?). Sorry.

You appear to be trying to use a Blockchain.info wallet identifier as the username when you're supposed to use a bitcoin address like 1Ba11ooNy2b8EyPwW5F56mJnhauDK7va5Z

BTW, you generally shouldn't publish your Blockchain.info wallet identifier. You still need to verify your email address with them.

Or make smoking in that particular place uncomfortable.. maybe by installing some powerfull lights.
This sounds like pretty reasonable balance between passive and active aggression. Cheap spotlight aimed at his smoking spot. Hear a cough, turn light on. No more cough, turn light off.

If he asks, tell him it's sound-activated to keep away burglars. He'll probably be too stoned to figure out why that's BS.

1787  Economy / Digital goods / Wall Street Raider (complex finance-business game), now available for BTC on: December 10, 2013, 07:50:32 PM
After days of talking (technically, since 2011), it looks like Wall Street Raider is now "sort of" for sale for BTC. The full version (with digital manual) is regularly priced at $29.95, while the "lite" version (without manual) is available for $19.95. Coins are worth the equiv of $1000, here!
Full - BTC.02995
Lite - BTC.01995

Wall Street Raider is one of my favorites. It's not a very pretty game, but the level of depth and complexity is unmatched by anything in the genre, and it's extremely difficult to believe it was all coded by one guy. In Wall Street Raider, you play an outlandishly wealthy individual, competing either against AI or other humans. Your goal is to (wait for it...!) accumulate the most money. WSR has a near-endless way of earning (and losing) money, containing such details as a dynamic interest rate affected by market forces (including you, should you be large enough) and the Federal Reserve (or appropriate central bank based on the currency you select.... BTC support not yet added), short and long Treasury bonds, interest rate swaps, corporate bonds, commodities trading, futures trading, unique industry types (aside from each industry having a unique set of random events, some are mechanically different in operation), and 11 different forms of taxation (and many write-off events).

Summed up another way: there is no other game ever created where there is a dedicated button to manually "prepay your income tax."



There's really no way for me to describe all the different ways to play (outside of writing large walls of text). Luckily, there's a shareware version which'll give you a pretty solid idea of all the different ways to experiment: http://www.roninsoft.com/download.htm

WSR currently only runs natively on Windows, but should function fine on (at least) Parallels, Crossover, or WINE (run the shareware version, first, though).


This offer is not currently available through Roninsoft's site. Instead, you have to PM me your name (or other identifier) and email address. This is then forwarded directly to the developer who'll personally send you a copy of the program with proper registration data in it within two days (probably within a few hours). You can PM me for a unique bitcoin address, or send me the proper amount of coins to 1FZzNjTtFNLuFFFKX2U2fWdT7jLR6bseTc and sign a message with the address you sent from with your name and email address.

Updates (excluding hotfixes for bugs) are sold for $9.95, but always include major new gameplay elements. Updates are currently only available for BTC if you have previously purchased a full game with BTC, and at a 10% discount over the USD price. Escrow through an automated service is acceptable (I'll pay the fee for the first three purchases).

Well, this is bitcointalk.org, not altcointalk.org. Many altcoins have their own forums and usually don't piggyback on this one for long.

1791  Bitcoin / Bitcoin Discussion / Re: "Real" full-node bandwdith consumption on: December 10, 2013, 03:50:54 PM
Updated image. Complete Nov. data and partial Dec. I now use "d" instead of "QT," so won't have "unified" data going forward.

I realized my flaw in this after wondering why the numbers were so freakin' consistent month-over-month. The "real" minimum is significantly lower than 9.5kB/s TCP. QT still downloads transactions to add to queue and relay, however. Since this transaction queue exchange appears to take significantly more bandwidth than block exchange, the download bandwidth limit is almost always reached. QT possibly prioritizes bandwidth, giving top priority to block exchanges instead of transaction exchanges (clever behavior if true).

I'll see if I can find the "truer" minimum. Will let it run in 24h spans at different limits and find the lowest possible without generating a block backlog. Stats in OP are fairly useless with that in mind.
1792  Bitcoin / Armory / Re: Armory - Crash on: December 10, 2013, 03:12:55 PM
Did not use Armory since almost a year. Changed nothing.

But today I had a COMPLETE Computer CRASH
after clicking the upper right Help(?)-Button in Armory window "RECEIVE Bitcoins"
"Synchronizing" and "Scanning" was completed before.

Nothing worked. All dead.
Had to KILL my pc by BRUTAL FORCE and much trouble to reboot and get my system running again.
Lost different not yet saved datas.

Messages in HELP MENU

1. "About Armory": does -as always- NOTHING

2. "Armory version":
"Your armory installation is UP-TO-DATE!" "Installed version 0.88.1"

NO Message that 0.90/0.91? seems to be available now.
0.90 not even mentioned in bitcoinarmory.com downloads

3. Never even tried the strange button "Revert All Settings"

Are you using OSX?
1793  Bitcoin / Press / Re: 2013-12-09 JPMorgan Chase Building Bitcoin-Killer on: December 10, 2013, 02:53:17 PM
Umm... It sounds exactly like Chase QuckPay (along with many similar programs at other financial institutions), which is basically PayPal without the middleman (the middleman being PayPal). It's a clear step in the right direction for financial institutions. It removes some friction, theoretically costs less (but since fees are charged based on how much banks feel they can squeeze, kind of irrelevant),  and is much quicker than the horribly outdated US money transfer systems used to move money around banks today.

What'd be nice is if JPM didn't try to copy Paypal (where it looks like it's going to act as the middleman when someone doesn't have a JPM/Chase account), but instead tried to copy the Shared Branching model credit unions adopted, where you can transfer money free and instantly to any other credit union (participating in the Shared Branching program), instead of just between your credit union's branches.
1794  Economy / Speculation / Re: PayPal president David Marcus: Bitcoin is good, NFC is bad on: December 10, 2013, 02:23:46 PM
Wow! Amazing news. Looks like Paypal's finally offering that missing link, a dual-currency (BTC-fiat) debit card!

1795  Other / Beginners & Help / Re: can't access encrypted wallet.dat - looking for ideas on: December 09, 2013, 12:57:28 PM
Since it seems to be something very slightly off, at least the brute-forcing should be relatively quick. No idea what the issue could be aside from what was already suggested outside of something stupid-obvious, like mistaking a "0" for a "O."

what do you mean print them, im copy paste it from my pass doc... shall i be concerned?
Both wallets and private keys can be printed. Private keys provide access to individual public keys. Wallets are the collection of private and public keys. AFAIK, there is not currently an easy way to print off encrypted private keys, so you should keep in mind it's much less secure (except in cases where you need to protect against yourself).

Yes I am thinking of way to protect against my self.

So, as follow up I was able to "brute force it". I used the Ruby script from this thread https://bitcointalk.org/index.php?topic=85495.300 posted by Revalin. See my post #312 for all the details.

Very grateful to everyone who helped me think this through.
There can be no closure until you satisfy our curiosity. Smiley What was the mistake?
1796  Bitcoin / Project Development / Re: [ON HOLD] 2^256 Deep Space Vagabond on: December 09, 2013, 12:41:15 PM
What is the probability (per check) of finding a valid, activated credit card number and selecting the correct CVV, cardholder's name, and expiration date, assuming the expiration date is not beyond five years into the future?

Maybe just for a US Capital One MasterCard credit card, to keep things simple. Uses MOD 10 algorithm. http://en.wikipedia.org/wiki/Mod_10 The first six digits of these cards are 517805. Digits 7-15 are unknown - the account ID #. Digit 16 is the MOD 10 checksum number.

This means there is a total pool of 99,999,999 accounts. Assume 10,000,000 are activated.

Expiration date is simple. Most (all?) aren't valid for more than 5 years. That gives a 1/60 chance of getting only the expiration date correct per check.

Cardholder's name is more of a clusterfuck. Let's assume only looking at "black" and "white" names (we're looking for a US account, remember) gives you 85% of all total active accounts. Let's assume common names make up 60% of all total active accounts, and that there are 50,000 common name combinations.

CVV is easy, and we'll assume we don't know how Capital One comes up with these numbers, so it's a simple 1/999 chance.

So. We need to successfully correct all of them in one go, and we have one ~1/10 chance (account #), one 1/60 chance (exp. date), one ~1/83333 chance (cardholder name), one 1/999 chance (CVV).

I think the per-check probability of all this comes to .000000000020020100300621424707921073926538% (low confidence, someone smart should check this because I originally posted this post as a question but ended up giving enough data where I thought I could solve it).

Keep in mind, per-check chance of finding funded bitcoin address is ~0.0000000000000000000000000000000000000000034211388289180104270598866779539%.

To make the numbers a little easier to grasp, here is %chance of finding bitcoin address if "DSV-like software can check 5000 addresses (10M of which are funded or will be funded within 6 months) per second, and 100 botnets of 50,000 computers each":
Per century,
0.00000000000000000000053944517054379188413880293137978%
If 100 botnets of 50,000 computers could check only 1,000 addresses per second (5x slower than above stats for bitcoin), the chance of correctly guessing info on an activated credit card is:
Per century,
10.01005015031071235396%

ETA: I left out PIN number. Point still stands.
