2601  Alternate cryptocurrencies / Altcoin Discussion / Re: Anyone with a lot of MH/s want to fork the TerraCoin chain? on: November 09, 2012, 12:24:17 PM
It's actually worse than pointless, since the addresses used start with a 1 the same as bitcoin.  This is something that the creators of the other alternate chains did not mess up!  A terracoin address is not easily identifiable as a terracoin address.

+1 I think this was a terrible idea.  What happens if we send bitcoin to terracoin addy?  Lost coins?

Actually I thought about it and no- the coins are not lost. If you sent Bitcoin to a Terracoin address, then the private key of the owner of the terracoin address you INTENDED to send to, will be the same private key as the Bitcoin address you did send to and vice versa. So basically you may have to ask nice, but the intended recipient on either chain will have the private key for the corresponding address in the other chain. So, no- they aren't lost coins.
And if I remember correctly, since sending from one chain to another is not possible, the coins can be recovered by doing some hacks on the wallet.

Do you plan to run off with people's money once you have about 25,000 Bitcoins?
Do you plan to run off with any ammount deposited?
2603  Bitcoin / Project Development / Re: HowTo: Viewing VRM temperatures under Windows(x64 as well). on: November 08, 2012, 02:30:01 PM
Because it allows building of more robust tools. It for instance now allows me to continue development of my program which monitors GPU sensors and tries to keep the system from overheating,fan failure. But VRM sensors were not exposed via the AMD ADL SDK.
Now I will monitor VRM temps trying to keep the system nice and cool. Plus, there is absolutely no information on the internet on how to do it.

And if everything goes as planned, allows me to develop a commercial non-free application. I just shared the instructions so everyone has a chance.
2604  Bitcoin / Project Development / Re: Viewing VRM temperatures under Windows(x64 as well). on: November 08, 2012, 02:26:31 PM
I was not asking for a tool. I was providing directions on how to build an application that is able to access VRM temperatures on Windows. Plus, GPU-Z is closed source and does not provide any code/tips on how to do it.
2605  Bitcoin / Project Development / HowTo: Viewing VRM temperatures under Windows in your application(x64 as well). on: November 08, 2012, 02:24:24 PM
Hi all.

A while back a user posted a tool called radeonvolt for Linux that was able to display the VRM temperatures and other sensor data for the HD5850. The tool was Linux only. I decided that something must be done for Windows as well, and came to a conclusion with satisfying results. While the GPU mining era is over, there will still be people mining with them various alt-coins even after ASIC hits.

Development in Windows is tricky, more so when you want to map physical memory to userspace. In Linux, you do it with a couple of lines of code, in Windows you need a kernel mode driver and must be digitally signed for x64 variants of Windows(which the majority of us use).
I tried with the KMDF framework, but apparently, Windows didn't like that, so I instead stopped on WDM(Windows Driver Model). Not knowing how to actually map memory, I googled and discovered this awesome driver on CodeProject that does exactly this.

I went in, and compiled PhyMem for Windows 7 x64, and pmdll which is a wrapper for accessing the driver with Visual Studio 2012(Was going to use MinGW but was advised not to for kernel drivers). I had compiled pciutils for Windows x64 last year, so I used radeonvolt with minimum changes to the code. PCIUtils for Windows is great, but apparently does not fetch the PCI Region size under Windows so I had to act blind on which address to use to map memory, for my 5850 under Windows it was the 2nd I believe.
After compiling radeonvolt with the needed changes, I was able to successfully display VRM,Voltage,Current and whatnot.
I noticed that the 5870 is similar to the 5850 in regards to the GPU registers and whatnot, so it was possible to make the code display sensor data from it, I don't know of any side effects though. Make sure you do not have multiple tools that do I2C on the card, or you may cause damage.
As for other cards, we need technical documents to understand the internals and write code for it.

In order to run self-signed drivers on Windows x64, test-signing must be enabled(Driver signing is not enforced on Windows x86). I was also given a link to a project that apparently bypasses driver signing requirement under Windows x64, but I have not tested it and I'm not going to discuss the legality of that now. Link http://code.google.com/p/bypass-x64-dse/

Mapping Physical Memory to userspace is dangerous. Any person with malicious intent aware of such a map may use it to gain control over the system, elevating privileges or doing severe damage with the power of just overwriting data on a specific memory address. Use with care.

I've had it too. It's a driver issue. Update the drivers if you have not done so, or downgrade to an earlier version.

2610  Bitcoin / Development & Technical Discussion / Re: SHA-256 broken, collisions found... Bitcoin then? on: October 27, 2012, 01:47:34 PM
Every world cryptographer has no reservations about SHA-224, SHA-256, SHA-384 or SHA-512, which is why a few of them including Bruce Schneier (who submitted Skein) thought the new SHA-3 standard wasn't necessary just yet, but NIST chose one anyways a month ago. http://csrc.nist.gov/groups/ST/hash/sha-3/winner_sha-3.html

I would assume bitcoin is fine, and they can probably go to SHA-3 whenever it needs to be done

SHA-1 is the problem http://www.schneier.com/blog/archives/2012/10/when_will_we_se.html
"A collision attack is therefore well within the range of what an organized crime syndicate can practically budget by 2018, and a university research project by 2021"
Ugh, no they can't. Since ASIC devices will be obsolete then. And if they are as expensive as today, well you can guess what happens then.
2611  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: October 27, 2012, 11:48:10 AM
Bitcoin also uses OpenSSL, and I noticed that they feed OpenSSL a seed on Windows. Is this perhaps required for Vanitygen for Windows, too(unless it already uses it)?

The OpenSSL documentation also states
Quote
OpenSSL makes sure that the PRNG state is unique for each thread. On systems that provide /dev/urandom, the randomness device is used to seed the PRNG transparently. However, on all other systems, the application is responsible for seeding the PRNG by calling RAND_add(), RAND_egd(3) or RAND_load_file(3).

In the first post it is mentioned that the Android heap limit is 4MB, on other devices it is 16 and 24 respectively. However, this heap limit applies to Dalvik, and not for Native code, so that's a solution, unless the author has already found a solution.

The average Joe cannot check file signature. An attacker could compile the client with malicious code and claim as original.

Hey all paranoid bitcoiners (like me)
What if one day 1 Bitcoin is worth 100 or even more usd, could there be modifications to bitcoin protocol, Because if 1 bitcoin is worth that much one day and its like 99% Stable at that point, could there be modification to  the official bitcoin protocol to avid something called "Getting a gun pointed to your head for BTC"

Yes i know it sounds CRAZY, but hey there are people putting guns to people heads for currency's like WoW Gold and of course USD haha..
Is USD the currency of every country? I think not, so please refrain from mentioning USD when instead you should have said fiat currency as to avoid proclaiming USA as the only country on the planet and USD as the only fiat currency.
2617  Alternate cryptocurrencies / Mining (Altcoins) / Re: [LTC] An (even more) optimized version of cpuminer on: October 20, 2012, 07:00:39 PM
Adding curses to the miner will make it seem more like cgminer and I don't think he wants to make "another" cgminer.
libcurses isnt an invention of cgminer!
Yes, it isn't. But it utilizes it, and since cgminer is based on cpuminer from which this cpuminer is based. He might think it will become a "cgminer". Of course, I do not represent his wishes or anything. Whatever he decides, is his own choice.

PPC = Digital Cash IMHO.  Cheesy

FTFY  Tongue

PPC needs people to adopt it or it wont go anywhere  Wink

With over 2 billion coins there is enough for everyone  Cheesy

The hard limit is 2 billion, it in fact does NOT have any limit to coins(yet or not ever).
2620  Alternate cryptocurrencies / Altcoin Discussion / Re: Why should/shouldn't I use PPCoin? on: October 19, 2012, 11:33:59 PM
Well, for starters, it's not just a copy of Bitcoin this time(not a full one at least). I've seen and participated in every single alt-coin so far, but all of them were blatant copies of Bitcoin with minor changes to protocol(such as difficulty).
PPcoin aims for 0% energy use, though that is not entirely true as the coins need to be mined for a while(hybrid design), but then you needn't mine to generate blocks. Proof of Stake is something very interesting imho.
