401  Bitcoin / Pools / Re: [400GH/s] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: March 06, 2013, 05:19:38 PM
It would be true, if we hash 10 times/day. But we have 300`000`000`000 hashes / second, so we CAN use it as fair number of tries and it "have" to balance .... in some point Smiley

The past has no outcome on future results. So, right now the current block has a 50% chance of taking between 3.4 to 4 days to find, and 50% of taking more than 4 days to find. (Median and mean are not the same in exponential probability distributions). The problem with p2pool now is that the relative variance is 27% greater than it was before ASICS (from 14 blocks per week +/- 3.7 to 9 blocks a week +/-3, poisson distribution)

Perhaps you can help with a conundrum with which I've wrestled for a while.

The number of shares required to solve n blocks can be described by a (shifted) negative binomial CDF, where size = number of rounds and p = 1/Difficulty.

As an example, the upper tail probability of more than 1.6 x 9 x Difficulty shares being submitted in 9 rounds is 0.05.

If the 10th round is more than 1.6 x Difficulty shares, the probability of this number of shares occurring in ten rounds is less than 0.04, and if the 10th round is less than 1.6 x Difficulty shares, the probability of this number of shares occurring in ten rounds is more than 0.04.

This relates back to rav3n_pl's comment, since it does imply that for an arbitrary number of runs of n rounds where the total shares submitted for the first (n-1) rounds is very unlikely, there will be more runs where CDF for the total of n rounds is closer to the median than further from it.

This means the nth round is more likely to be shorter than longer. Not shorter than average, but just shorter, and therefore luckier.

So I think I'm misunderstanding something about the way this "paradox" should be interpreted. Where am I going wrong?

Good question, heading out but want to think about it a bit more later. I think it may has to do with conditional probability, which ties into gambler's fallacy (unless I'm reading this too quickly). While it is far more likely to have 1 lucky round and 9 unlucky rounds than it is to have 10 unlucky rounds, if you are sitting at the tenth round it is equally probably to have a lucky or unlucky round regardless of what happened in the past. You can also approach this as a conditional probability problem when for isolated random events (P(A given B) = P(A)P(B)/P(B) when P(A) is not affected by event B)

Here is a worked out example showing that although it is far more likely to have a certain outcome in n-tries, the probabillity of an event occuring on the nth try is independent of the previous trials.

Eh, we just need few seriuous miners to put pool power over 700GH.
This way we will have over 3 blocks per day and all shares can be used in less than 24hrs of payout.
I`m surprised, that there is no new miners now, because (looking on L graph) it ALWAYS was big jump after hole like we have now.
Switch to P2pool NOW! Cheesy

Is 2122's argument, "because it is inconvenient to my business practice I will violate the license agreement?" So if I out-license a patent to you for a fee, will you just stop paying me because it's better for you to not pay me than pay me?

You can take that position, but license violations open you up to lawsuit liability (cease and desist at a minimum, and damages at a maximum).

If you don't believe me, google Aaron Swartz...

Also, Avalon agreed to the terms of the GPL by using the software. No one forced them to use it. If they don't want to disclose code, then just write your own miner software (like BFL did with easyminer...)

If you want to use cgminer, then follow the terms of the license. The alternative is not use cgminer.

EDIT: I'm in small business hardware and software. I sometimes choose GPL and sometimes not, depending on my strategy. Avalon can do the same.

Is the 30days from someone who recieved the binary and makes the request?

Or is the 30 days applicable from the day of releasing the binary to someone who doesn't have a right to ask for the source code. (not even a customer, did not receive the binary, ?therefore can't make it a request on legitimate grounds?)

When does the clock start running and what is the basis at which it starts the 30 day limit?

I actually do not know, that is why I am asking.

Well, technically, there is no 30 days. If a customer requests code, and you do not provide it, you are immediately in violation. Technically you're supposed to stop distributing immediately and are liable to legal action if you continue. At this point two things can happen:

1) you "fix" it and start distributing source code. After 60 days of "good" behaviour, the violation evaporates and you have the full license to distribute again.
2) you don't fix it, and a cgminer dev tells you you are in violation. The cgminer dev does not need to receive the software, but only needs to have evidence that one of your customers was denied access to the source code. At this point you have 30 days to fix it, if you do you get your full license back automatically.
3) cgminer devs can just tell you that your license is terminated, due to the violation, and you must cease distributing the software in binary form.

(see section 8 of GPL)

GPL disputes are best handled politely and in good faith, not with the copyright holder going after the fork with guns blazing and the fork going into a legal turtle shell. So there is language regarding 30 days to "cure the violation," but you really shouldn't be using it like a clock.

Did a business seriously start a public thread just to taunt the (volunteer) developer of their software platform? With friends like these, who needs enemies...

Summary of events:
1) Avalon wants miner software, decides cgminer is a good platform and decides to use it (OK)
2) cgminer's developer asks for hardware so he can properly include it in cgminer (OK)
3) Avalon declines the offer (OK) and finds someone else to code it (OK)
4) Avalon shipped devices with binary code (OK)
5) The cgminer developer requests source code via 6b of GPL-v3. (OK)
6) Avalon has 30 days to remedy the situation (section 8 GPL-v3, OK)
7) Avalon drags feet as to not give a competitive advantage to competitors (OK), cites "technical" reasons but it doesn't matter, they can just drag their feet.

Why taunt Kano? Fulfil the request (or be liable to legal action) and take care of customers - what's the point of this thread?

Your summery is pretty accurate, except for the fact that Kano can't request the source code, as he's not a customer, and I believe a Mod split this thread out of another one. I do love how they use cgminer software, and then bitch at a CGMiner dev for getting involved. Really?  Roll Eyes

Yeah, that's a GPL-v2 thing, not v3. Only those that actually receive the binary code can request it.

You sir are a real gem, one of a kind (I can only hope).

Are you often ignorant simply for the sake of being ignorant (I think yes!)

First of all LOL at lawsuits I am not even sure how you managed to get there from my post but ah OK cool!

Perhaps in its literal definition forced was not the perfect word.  I guess me assuming that someone reading the post could get the "jist" of it without translating every word literally we're just slightly optimistic?

Would you prefer if I said something like The current ASIC vendors have decided to only accept full payment pre-orders thus shifting the burden of risk from themselves to the customer?

I feel weird saying this, but I agree with Jeff. Customers chose to bear risk, and they may be rewarded (or burnt) by that choice. However, you should make the argument that ASIC vendors misrepresented the risk by over-promising. The counter to that is that all vendors, accept BitcoinASIC, have either delivered products or are offering refunds to anyone at any time.

So in the end, the only argument you have is that ASIC vendors made things inconvenient for you (if you were someone that priced risk somewhere between the initial offering and the current state) or that BitcoinASIC took your money and ran.

"You all knew the market was big enough that enough people would be willing to take any option given them, greed blinds after all." - Something is in such demand people are willing to buy it at all costs, isn't that economics 101? Put it differently, given the choice of no pre-sale or pre-sale, the market overwhelming is calling for a presale (this is demonstrated by the fact that they still have orders even after the delay and the risk became evident).

Why not just use the arduino itself? store in EEPROM:
http://arduino.cc/en/Reference/EEPROM

Or just put an SD card on to the Arduino:

both of which are much cheaper than FPGA. The cheapest is to print out a physical address and send it to your piece of paper.

Your English is terrible. "could be the dead of Silk Road". lol

"in the wiki". wow. good for you. I don't care.

The economy IS the exchanges. This is where the value is set. Who gives a shit if people use them for real world transactions. I'm not concerned with the economy past where I turn them into dollars.

Silk road and free market reloaded sell more than just drugs. You can buy guns, passports, poisions, and even have someone send a ricin bomb to a numpy like you.



Obviously you don't know anything about what economy is and how economy mechanism works. You obviously don't know anything about black market subject you just should shut the fuck up or educate yourself.

While I don't agree with the language, I agree with the argument. Value comes from what people are willing to trade for a real good. The reason why the exchanges exist at all is because people are willing to exchange real goods for bitcoins. They are also willing to exchange real goods for fiat. If at any time people no longer want to exchange goods for bitcoin or fiat, the exchange rate will skyrocket (or plummet). If no one wants to give you something for your bitcoins, they are worthless and the exchange rate will follow. [This excludes speculation, which can't be the basis for a stable economy]

Should be optional

It is optional, once you opted to publicly link the address to your bitcointalk screen name they are linked permanently. You made the choice, if you don't want to link them - don't post them together.

Same goes with facebook, twitter, etc. - if you don't want something going public, don't post it publicly.
417  Bitcoin / Hardware / Re: [Announcement] Avalon ASIC Ships on: January 21, 2013, 03:43:06 AM
One of the benefits of Open Source Software is that anyone can do anything with it, until they provide source code of all changes (correct for GPL and other similiar licenses, but not for BSD-like license for ex.). Kano, I suppose that you don't think, that you only one who can write code for cgminer? Avalon can release patch for it and you will decide include it in trunk or not. But I'm don't think, that Avalon will be upset, if you decide not to do so...

I think that is Kano's point: it's OSS, Avalon is free to patch it and support it however they like. Of course if they do, they have to distribute source code as well.

However, if they want Kano to patch and support it, he wants hardware in return. I think that's fair, and they can say "no thank you" to the deal, it's their choice.

You're allowed to sell GPLed software as long as you follow the license (provide source code).

I Cancel my 20 Jalapenos ... and its Done ...

You bought 20 Jalapenos? Even if they were shipping today you should cancel your order, that's a waste of money

20x4.5 GH/s = 90 GH/s for 20x$149 = $2980


For $2598 you could have had 120GH/s if you purchased 2 singles...

It appears that the discussion is over (no refutation of counter-arguments or clarification of the central argument by the OP), and it is clear that the First Law of ASICs does not stand on any sound position.

Bonker, for future reference you can practice getting better at arguing a position by reading Paul Graham's essay:
http://www.paulgraham.com/disagree.html
420  Bitcoin / Mining / Re: The First Law of ASICS on: January 07, 2013, 05:10:39 PM
What's in it for the manufacturers to delay? You say it's in their best economic interest, but why/how? Unless they are mining on their own with the hardware (which there is no evidence that they are), their only best interest is to sell as many for as much as possible. Delaying sales doesn't do anything for them, in fact it reduces the number of sales they can make.

1) If one of the ASIC manufacture sold devices a month earlier than everyone else they have a huge competitive advantage over their competitors, and that advantage has significant value. What do they gain by giving it up and delaying?

2) Some ASICs are not for sale, but for lease. They will mine on their own hardware and thus get it at cost. What benefit does that company have at delaying their own production and profit?
