222  Other / Meta / Please Highlight The "News" Section... Especially Right Now! on: June 20, 2011, 10:03:30 AM
With all that is going on.. I feel it is important that the news be read at the top of the forum. Right now it is fairly easy to glance over it, but the announcement about the mtgox hacking is a must-know for any bitcoiner and should be highlighted more thoroughly I believe.
223  Bitcoin / Mining / Re: What are some of the dangers of voltage tweaking GPUs? on: June 20, 2011, 09:34:02 AM
Take a heatgun and point it at the VRM/power intake.

I'll give you a hint: It's about 110 celsius when you operate at stock frequencies which is well past boiling point.

It jumps up to 130-140c even with a 15% overvolt.

Yes it can be sustained for a short time, but it's simply dumb for 24/7 operation.
It makes no sense for bitcoin mining. It might make sense for short term gaming gains.

Core temp of the chip itself tells nothing of stability like pointed above (but it has a much lower thermal threshold than VRM; it will downthrottle at about 100c.

What card are you using that has 110 celcius at stock freqs? And is that when bitcoin mining is going on at 100% load you mean?

UPDATE:

So it wasn't my video cards, motherboards, PSUs, or anything that I paid decent coin for...

It was a fucking $3 cable from Hong Kong that melted almost instantly after it reached above 500 Watts of power.

The thing was rated 10A 250V but was thinner than a strand of my hair. I should have thought about that before but it was hidden (tucked away) behind my tower of rigs and thus explains why I couldn't see or smell any noticeable damage.

My carpet is now burnt to a crisp and I am lucky I didn't burn down my entire place.

I'm glad we heard back from you - I thought you tried this and roasted yourself.

Lol thanks for the kind words Wink
226  Bitcoin / Pools / Re: Do Pools Generally Keep The "Generated Fees" Associated With Each Block? on: June 20, 2011, 07:43:27 AM
Yes.

I guess this is because

1) Getting the value of the transaction is harder than just setting it to 50BTC.
2) Pools aren't trivial to run, and they deserve some benefits.

I'm running a trial on my pool where we pay out the fees on the block as well as the 50BTC, but I don't know how sustainable it is in the long term.

A lot of pools only payout up to 2 decimal places. If a user leaves your pool, can they withdraw all 8 decimal places of their BTC?

This irks me too.

It's like a hidden tax for using their services if you cannot cash out 100% of your earnings.

I am sure that as the bitcoin client progresses however that the larger pools will implement such things.

Bit rot is only one of many problems. Worse would be complete failure of the device.

I recommend paper as a long term archival solution: http://www.ollydbg.de/Paperbak/index.html

Thanks for that, pretty amazing you can store 3MB on a sheet of Paper.

I remember buying a Mac 15 years ago that only had about 80 MB of hard disk space... or about 27 sheets of paper's worth Tongue

yeah, please do. Mt Gox claimed the attack originated from Hong Kong.

How come nobody else has been able to do this yet?


Because MtGox_client.exe was not the "thing" or "person" responsible for hacking MtGox. Only sending spam emails.
229  Bitcoin / Bitcoin Discussion / Re: Mtgox charity fund on: June 20, 2011, 07:05:22 AM
Mtgox lost a lot of money in their downtime that they would've made in transaction fees. Also they will have to reimburse someone for $1000. Would anyone like to contribute to a charity fund for Mtgox?

Obvious troll is obvious.

Great work.

Please do keep us updated.

Note: That is probably note the actual hacker of mtgox, but the bastard spammer who tries to steal your bitcoins via email because of all the recent mtgox hype.

233  Bitcoin / Bitcoin Discussion / Would it be beneficial to copy your wallet.dat file across an entire backup usb? on: June 19, 2011, 07:17:18 AM
I was reading about bit rot and began wondering about my backup ideas.

If I copied my wallet.dat file 1,000,000 times across the entire partition of my usb drive... or perhaps created ~20 partitions that each contained a copy of the wallet.dat file...

Would I somewhat protect myself against bit rot?

It sounds like it only affects single bits at a time and on a specific area of the drive. So if I made multiple copies on the same drive then surely one copy would work correct?

Obviously I will be replacing my backup media every year or two but the less often I have to the better.

If I could just create 1 million copies of my wallet.dat file and leave it on a USB until the product itself deteriorated that would be amazing.

Somebody told me about OTP (One Time Programmable) solutions as well but they are not easily attainable, or so it seems. Know of any good links?
234  Other / Meta / God Almighty, Where Are The SHARE BUTTONS?! on: June 19, 2011, 07:06:52 AM
Come on now people... we are experiencing a massive influx of users.

Let us use this to our advantage and place web 2.0 "share" buttons on every page of this site.

It doesn't have to intrude on anything whatsoever.

If nobody knows how, I will offer up my time to create a custom banner of the top 10 "submit your link" type sites as well as email/browser favorite saving and we could place it right up beside the title of the "Bitcoin Forum" in the top left of the page perhaps?

I could make a "Share this page" html button that opens a list of "shareable" sites when hovered over or whatever you want really...

Or there are tons of tutorials online that will help whoever is running this site set it up themselves.

Either way, it's pretty silly not to have something like that on a site such as this.

If the right person tweets or facebooks us... we could receive free advertising worth tens of thousands of dollars... and it doesn't cost us a thing.

PM me if you need me to do anything. I don't check the meta subforum often.

I'm trying to get some bitcoins/mtgox money with my moneybookers account in USD, what options do I have?

I know there's VirWox but the volume on there seems very low, and the fees seem high.

Thanks

Try cashing out the moneybookers and simply buying a money order from your local bank/post office?

So wait...are you trying to sell all 10,000 at once?  I need enough to register 1 domain.  If you can provide me that I'll pay ya a little.


Pretty much, yes. Don't have much interest in retail sales.

Will leave this thread open and bump it from time to time until they're all gone.

That's right, I just found I got accepted to speak at DEFCON 19 about bitcoin.

I'm open for input, giving a 20 minute talk.

Input?

We need programmers, we need programmers, we need programmers.

That is all.

EDIT: For the bitcoin client, startups, oss, anything bitcoin related!

240  Bitcoin / Bitcoin Discussion / Re: The point of bitcoin on: June 19, 2011, 02:42:49 AM
Recently I've read a lot of claims that Bitcoins don't have intrinsic value. I've come to a different conclusion. Bitcoins have intrinsic value if they enable desirable interactions that are not possible without them. Bitcoin is a theoretical and practical breakthrough that makes it possible to decentralize services we couldn't previously decentralize.

To elaborate: Bitcoin isn't just a currency but an elegant universal solution to the Byzantine Generals' Problem[1], one of the core problems of reaching consensus in Distributed Systems. Until recently it was thought to not be practically solvable at all, much less on a global scale. Irrespective of its currency aspects, many experts believe Bitcoin is brilliant in that it technically made possible what was previously thought impossible.

The Byzantine Generals' Problem roughly goes as follows: N Generals have their armies camped outside a city they want to invade. They know their numbers are strong enough that if at least 1/2 of them attack at the same time they'll be victorious. But if they don't coordinate the time of attack, they'll be spread too thin and all die. They also suspect that some of the Generals might be disloyal and send fake messages. Since they can only communicate by messenger, they have no means to verify the authenticity of a message. How can such a large group reach consensus on the time of attack without trust or a central authority, especially when faced with adversaries intent on confusing them?

Bitcoin's solution is this: All of the Generals start working on a mathematical problem that statistically should take 10 minutes to solve if all of them worked on it. Once one of them finds the solution, she broadcasts that solution to all the other Generals. Everyone then proceeds to extending that solution - which again should take another ten minutes. Every General always starts working on extending the longest solution he's seen. After a solution has been extended 12 times, every General can be certain that no attacker controlling less than half the computational resources could have created another chain of similar length. The existence of the 12-block chain is proof that a majority of them has participated in its creation. We call this a proof-of-work scheme.

If that sounds confusing, don't worry. What it means is just that consensus is reached, because computational resources are scarce. You vote with work. To rig the vote an attacker would need to control more computational power than the honest nodes. To ensure it's more expensive for an attacker to purchase the computational power needed to attack the system, Bitcoin adds an incentive scheme. Users who contribute computational power get rewarded for their work. If the value of a Bitcoin rises and thus attacking the system becomes more profitable, it also becomes more profitable for honest users to add computational resources. At any given point, one would expect miners to invest as much resources into mining as is profitable for them. Bitcoin is a currency, because it needs incentives to protect the consensus process from attackers. This computational process ("mining") is not wasteful at all, but an incredibly efficient way to make attacks economically unprofitable. Bitcoin never uses more computational resources than neccessary to protect the integrity of its interactions.

Now let's go back to discussing the value provided by Bitcoin. Essentially it's a means to make consensus in highly distributed large-scale systems, which would otherwise never be able to reach consensus. The value of this is, that it's now possible to build applications in a decentralized fashion, that we previously thought could not be built without a central authority. The most obvious value of Bitcoin is as a medium of exchange for goods and services that can't be easily bought or sold using cash issued by a central authority. But there's more. Bitcoin also makes it possible to fully decentralize the DNS (Domain Name System). In that case, every Bitcoin Domain Name already comes with a cryptographic key pair. That means it also allows us to solve the PKI (Public Key Infrastructure) problem - every name you connect to has an encryption key associated with it that can be verified without trusting a central authority. In case network traffic monitoring prevents people from accessing information either at all or anonymously, Bitcoin makes it feasible to pay for internet relays that anonymize or reroute traffic - that is, it makes it easier to remove central control and fight censorship. The list goes on, I've been hard-pressed to find any decentralization schemes that would not benefit from Bitcoin integration

The pattern here is: Pretty much all of these applications can already be built in centralized form. But often the centralized solution comes with a whole bunch of weaknesses. In the PKI case you'll have to trust over 300 Certificate Authorities every time you make an https:// connection, many of which are located in countries with repressive governments. If any of those 300 entities get compromised or malevolent attackers will be able to read your email, access your bank account, and violate your privacy. DNS is getting censored by governments because they can. And every time you store value in currency, you're trusting a central authority that it isn't mismanaged and thus depreciates in value.

Is there value in Bitcoin? Let me ask a counter question: Is decentralization valuable? If you think that we'll increasingly lose trust in the central authorities that manage the infrastructure we rely on, you might expect Bitcoins to rise a lot in value. If not, that is you believe that authorities will be able to tackle the challenges of the future better in centralized form, then from your perspective Bitcoins don't add value. We'll see.

Let's not get into the habit of post-jacking (STEALING) other peoples write ups on bitcoin guys...

Especially the smaller websites.

If this guy spends the time to do a huge writeup on bitcoin and only gets 5-10 page views... what are the chances he will write about it again?

In the future please go the the site and read the article there.
