Will check it out, with my tools related to my sig.

In light of this, I received an email from CampBX(somehow), but it was in my SPAM folder in my Gmail account. Coincidence? Phishing?

i just noticed that newegg seems to be selling some
very misleading "miner packs"... computing parts
that would be fine for anything BUT mining Bitcion.

What's up with that?



Geforce rig for over $1000....... WTF are they thinking, is this a 2012 noob mistake?
It isn't, the nvidia cards can now mine altcoins...as efficiently or even better than AMD.

On a somewhat related topic I wonder how cost effective a small nuclear power source would be in powering ASICs.
If you are dead from radiation poisoning before the miner sends a share, not much.

Thanks again for the comments everyone. The 0.1 payouts are done now, so any more comments about mathgate.info will be for free.  Smiley

It is good to have gotten this feedback. We'll make use of it.
Perfect. We are in 2014, your layout looks like it was done in 1999, no joke there. There are dozens of free templates out there(that could kill a Core2Duo). Honestly, the website is painful to look at.

Wow, an image strung together by incoherent meanings. People usually write whitepapers for these kind of things.

well, at least it's not complaining about a missing file anymore - progress Wink

But it says it can take minute, then nothing happens :/
It exits for some reason.

How do you know Gatekeeper isn't going to share the winnings with those who contributed to solving the puzzle? Instead of bashing him, why don't you post your addresses and see what happens....
Because he shouldn't have attempted to win this, he has 1510btc, in one address(which is bad), and he claimed ANOTHER prize. I say somebody else should have gotten this, I mean the dude has almost a million $ from BTC, yet he also got 3.5btc more
790  Bitcoin / Bitcoin Discussion / Re: ARG Puzzle with 3.5 BTC Private Key Prize **Game Over** on: July 06, 2014, 11:37:47 PM
I also think the solution is idiotic. No way could anyone find it without not one but two hints:
- "One small now is tall."
- Picture with Alice with letter "W" marked all over it.

What's the point of a puzzle that can not sustain itself, and relies on numerous hints to be solved?

I agree with this. This was terrible, and there were many points in the puzzle that relied on incredibly arbitrary leaps of logic, and therefore, clues from OP. I'm not a genius at puzzles, but who would've swapped the 'W' case without being told about it? I think the answer is obviously: nobody.
I don't think so, some people have solved Cicada 3301 puzzles way more complex without anybody's help.

That seems to have gotten the speed back up to what it was.

I still have the system crash if I run two instances of it with different video cards...any idea what is causing that?

I map one instance to -D 0:0 and one to -D 0:1 and still have a third un-used GPU in the system but the system crashes.
This sounds like a driver issue to me.

Running 14.4 Catalyst -- any suggestions on what to do differently? I must have misunderstood, I thought the driver issue was the problem your binaries were solving?
No, the problem being solved was this one

Quote
CPU hash: 62877214296428cff20ae302409afcabd66b05f1
GPU hash: 86c80e8df57566f7401c78c932b0862b13269b7e

The mismatch basically.

Friends, I can't tell you how impressed I am with all of you. I have been following since the start, but had nothing to add. This was way out of my league, yet I have followed obsessively. I have learned so much from all of you. Such brilliance! And great collaboration. Please don't bash the OP. She's an uber-talented, multifaceted woman--an artist, a coder, a puzzler--Wow Wink! She generously donated her brilliance, her time, and her btc. We all were intellectually stimulated and entertained for 2 weeks. The experience was its own reward. Nice job, everyone!
I was out of it's league as well, but the end result is that somebody with 1500 btc got the prize, that was not only anticlimactic, but greedy.

Woah, somebody with over 1k btc got the prize? That's pretty...pathetic.
795  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: July 06, 2014, 11:22:44 PM
Alright, looks like user nonnakip was on the right path, it's the BFI INT patch that causes this problem. Try these binaries https://www.dropbox.com/s/o5genfs5ul4ryuw/OCLVanitygen.zip.

For an actual source code patch, find this

Code:
			//if (dvn && strstr(dvn, "cl_amd_media_ops"))
//quirks |= VG_OCL_AMD_BFI_INT;
and
Code:
		//if (drv && (strstr(drv, "1112") || strstr(drv, "1113")))
//quirks |= VG_OCL_CATALYST_WORKAROUND;

remove them and recompile.

Don't forget to remove old .oclbin files.

I spend several hours getting oclvanitygen working with AMD Radeon 7xxx on 64-bit Linux - Ubuntu 12.04 and Ubuntu 14.04. In the end only the following is needed:

  • Ubuntu drivers
  • vanitygen patch
  • 1 userspace library file from AMD APP SDK v2.7

I created a minimal instruction text file. Maybe this will save someone some hours of searching the internet.

https://nastyfans.org/download/oclvanitygen.txt
A similar patch for Windows exist, I've detailed it in my post above.

I've downloaded your patch and overwrote the files that were included in my oclvanitygen folder with those that were in your binary dropbox zip. I'm running a Windows 7 rig with 3x R9 280x with Catalyst 14.4 and it is hashing much slower now.

Previously I was using this command:

Code:
oclvanitygen64 -D 0:0 -k -v -o output.txt -F compressed 1RainMan

Now I'm running it with:

Code:
oclvanitygen -D 0:0 -k -v -o output.txt 1Rainman


and am getting around 5.6 Mkeys/s on a r9 280x ... that's significantly slower than what I was getting before (around 15 Mkeys/s+).

Any idea what I'm doing wrong?

Thanks!
Hmm, now that I look at it, I don't think it's producing valid addresses. Try testing with an address say 1abc and see if the output starts with 1abc. Looks like Mr. Yu wasn't correct. But I wasn't paying attention myself.

6EQUJ5 is a reference to the Wow! code: http://en.wikipedia.org/wiki/Wow!_signal
Maybe we need to do something with 6EQUJ5 and the code we extracted. Just don't know how.

OP posted

- 6EQUJ5
- No sha or hash needed
Confirmed. I saw it too Wink
800  Bitcoin / Development & Technical Discussion / Re: Why no minimum # of TX in a block? on: July 06, 2014, 03:51:12 AM
The number of transactions in a block is determined by the max block size, which in turn is determined by the size of transactions. Also, the bigger the fee, the higher the chance the tx gets included in a block. But some miners might decide, hey, I want only high fee transactions, in which case max block size may never get hit, and only say 50 TXes get included in a block.

yes i know that, however that block which I linked has no tx other than the network subsidy
The reason for this is, because the block was found so soon after the previous, the mempool of the miner was empty at the time, i.e it didn't choose to not add TXes, it just happened.
