The quad board is not their only product.
They have a wide variety of fpga products, so it can be possible the day the delivery guy was outweighed they had another big delivery.
But I do belive they've sold much of them already.

You changed from SHA256 to MD5.

Your Trust string looks like this:

md5("[[1,0,0,0,1],[0,1,0,1,1],[1,0,1,1,0],[0,1,0,0,0],[0,0,1,0,0]] 6194c0e2ffb667fa41385e16d9fb010b")

Due to weaknesses in MD5, it is entirely possible to fudge the array (on the left) and quickly compliment the arbitrary string (on the right) to generate a colliding MD5.

If you are going to continue using MD5, I recommend replacing the long arbitrary string with a sequence of 3 common dictionary words that maintains a strong entropy but makes colliding MD5 values nay impossible.

I would recommend just using a different hashing function.  Since the left side is of known structure, just differences between 1s and 0s, one could easily start a game with 24 mines, giving only 25 possible forms for the left side.  Then, it's just a three word dictionary attack... if you pull from too small of a pool of words then coming up with a rainbow table becomes relatively easy.  Someone could setup a bot to run you dry, irreversibly in a matter of minutes after the rainbow table was created.  Go with a different hash function.

The first line of the quote states that you went from SHA 256 to MD5.  Why?
I think you forget the 128 bits of the last part "6194c0e2ffb667fa41385e16d9fb010b"

I decided I don't like the fact I already have to pay the full amound and get the units months later, so instead I'll probably invest some money in buying bitcoins and investing them on glbse.
That way I already start making profit right now and I have less work to do myself. (I already have to much little hobby projects)

Ordered one jalapeno.
I got my confirmation email the 24th.
Got the email about the payment the 29th.
Decided to cancel it the 29th Tongue

Although I'm an atheist, I very like the idea of a shariah compliant fund. I don't believe I've seen anything like this, thus it creates a new market.
Good luck with it!
1628  Other / Beginners & Help / Re: SHA256 Collision Attack on: June 29, 2012, 07:30:40 AM
I don't know about the others, but you can have my 10BTC if you can show a sha256 collision.
But the bitcoin address is something else, I don't bet about that (yet?).

It is possible you have the keypair for the address with you name in it, but I don't know how you made it. It still is possible for you to have choosen your name because of that address.
However, if you really think you can generate a specific address, I can make a new address and put some bitcoins on it. Then I tell you the address and you generate the keypair and have the bitcoins.
But if it is possible to do that, why not just choose some used addresses and use the coins on it.
1629  Economy / Securities / Re: Can someone explain 2 factor auth to me? on: June 28, 2012, 09:19:29 PM
There is (was?) some kind of error in glbse when I first tried 2 factor auth.
If you first enable the 2 factor auth and then download and do the stuff with the google account, you don't get a barcode to scan to setup the app.
You have to mail support@glbse.com about it, they can reset it for you.

Unfortunately I'm in no position to prove this yet, as I don't know how to 'sign a message'
and have no BTC to spend... Sad

You now have 0.0638 BTC from me... assuming you have the private key to that address.  Send it anywhere, and your claim that you own the address is proven correct.
Following, http://blockchain.info/address/1ELECeJompinDox61L73eAUyaWpe3Q5HZB


How easy would it be to "vanitygen a bunch of 9-character semi-pronounceable string and pick one that looks best"?
The base58 part contains out of the characters "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
vowels : 3 uppercase, 5 lowercase. (AEUaeiou)
consonants : 21 uppercase, 20 lowercase.
numbers : 9

If you want it like JompinDox, 3x (consonant vowel consonant) with the first and seventh characters uppercase, your chance will be
21/58 * 5/58 * 20/58 * 20/58 * 5/58 * 20/58 * 21/58 * 5/58 * 20/58 = (5^3 * 20^4 * 21^2) / (58^9) = 8820000000 / 7427658739644928 = 1.1874535851954921019166981507839e-6
1 / 1.1874535851954921019166981507839e-6 = 842138 tries.

But IIRC the bitcoin address is a 1 followed by 33 characters of the base58 string.
So you have 25 places it can occur, making it 842138 / 25 = 33685.52 tries.

(about the last part I'm not 100% sure, but I know for sure it gives you a better chance so lowering your tries needed)

They've said somewhere in some thread (can't find it), if you placed the order on 23th, get the mail on the 26th, paid on the 27th, you paid in 1 day and ordered at 23th so placed at 24th in the queue.
1632  Other / Beginners & Help / Re: Pool Hardware on: June 27, 2012, 12:59:23 PM
You forget the bandwith.
If you count 1kB for each getwork from client to server, 20GH/s give you somewhere around 5kB/s for the getwork data.
5 kB/s = 421 MB/day = 12.5 GB/month
I have know idea how much data it costs to stay on the network (receiving new transactions and blocks), but that part is the same for each pool.

For the OS, I would advise the one your most familiar with, ubuntu in your case.

For 32 or 64 bit, if you don't have more than 4GB in your system 64 bits is useless.
64 actually costs a little more memory because the pointers are bigger.

About the rest I know nothing or close to nothing Smiley

I've sent 300 euro last week to intersango.
Bought bitcoins for my money and transfered them to my glbse account.
It all worked perfect and pretty fast.
1634  Other / Beginners & Help / Re: Development of a mining-client on: June 26, 2012, 11:46:37 AM
Oh, and if you change to something other like litecoin, you just have to update the sha256(sha256(work)) to scrypt(work).
You don't have to think about difficulty of little protocol changes.
1635  Other / Beginners & Help / Re: Development of a mining-client on: June 26, 2012, 11:45:03 AM
I would go with the getwork way.
Upside, a lot less protocol handling so faster result.
Downside, for solo mining you need to setup other software for your own pool.
1636  Economy / Services / Re: Gigamining / Teramining on: June 25, 2012, 12:52:42 PM
Giga is smart as hell : just like BFL is forcing the current FPGA buyers to spend even more on BFL so is giga forcing the current bond holders to upgrade for a fee so he gets even more $$$

Well played, gigavps !

Hats off to you.

I still believe pirate = gigavps = BFL = government but that is conspiracy theory so disregard it Wink !

If A=1, B=2, etc. then
PIRATE = 15 + 8 + 17 + 1 + 19 + 4 = 64
GIGAVPS = 6 + 8 + 6 + 1 + 21 + 15 + 18 = 75

You will notice the difference is 11.

9/11.

11 days ago, Gigamining was trading over 1.1 The same price as PPT.C. Pirate's code is 64. C=64. A machine favored by Hackers for it's versatility.

Also notice that there are 5 mHash/share for each GIGAMINING bond. GIGAMINING's code is 75. 75 divided by 5 is 15 -- which is the current valuation of a mining bond -- 15 bitcents per share.

GOVERNMENT = 6+14+21+4+17+13+12+4+13+19 = 123.

Easy as 123.

64 + 75 - 11 = 128. C=128. Commodore 128. The next machine in the series after the C=64. This will all make sense in a moment when I tie everything together.

Notice C=128. There are 28 days in 1 period of pirate dividends. GIGAMINING is 64, and pays out about 6% over 4 weeks. This is the first hard clue that PIRATE = GIGAVPS. Also note that the moon, which is represented by the cycle of 28 days per pirate dividend (PPT) has 13 months per year. I do not know how this fits in precisely but it obviously has something to do with the number of people involved in PIRATE and GIGAVPS. Perhaps another researcher can supply the missing link. I would start by considering the number of outstanding shares divided by 123+9/11.

Please, this is urgent. I have given you the tools now it is up to you to chip away the statue and reveal the TRUTH.
It all falls to place now!

Must... invest... more!...

Can I get one with my own private blockchain?
That way I can even increase the mining further by setting the 10 min/block to a lower value.

Anyone setting up a GLBSE share or bond for miners who can't affort a complete unit or doesn't have the correct energy to run this?
I'm willing to buy some shares/bonds right from the beginning of january 2010.
I'll probably send the dividend right back to january 2010 to buy even more shares.
