BTC-E at 99. Given that Mt. Gox USD cannot be withdrawn easily right now, this is probably the best indicator of market price.
Edit: now 97.6
That is not true. Obviously you don't use Mt.Gox services. If you live in the US, the only ways out of Mt. Gox are through Camp BX and through Coinbase, both expensive. Some find it cheaper to buy BTC and withdraw that way. |

Ripples are not intended to store value. They are intended to facilitate transfer of things with actual value. Therefore, the market will not assign much value to ripples.
One Bitcoin buys you 10k Ripples currently. There are 100 billion Ripples in existence. You calculate the implied market capitalization. I wish people would stop falling for the OpenCoin propaganda that it's not a competitor. OpenCoin's business model consists of holding 50% Ripples and hoping they appreciate in value.The market capitalization is based on the promise that only half of all ripples will be distributed, with the rest owned by OpenCoin. So divide your implied market cap is only 5000000 BTC, less than half of all BTC in existence. |

I don't understand this sentiment that Ripple has no underlying value. How is that any different than bitcoin? Seems to be an entirely subjective valuation in either case. I certainly didn't mind making a few coins off the free ripple giveaway.  Value is based on value. It sounds stupid, but it's true. I can make an exact copy of Bitcoin and it would not be any different from Bitcoin, but the currency would have a vastly different value. Bitcoins only have value because people believe it has value. People believe it has value because that's what it was intended as. If Satoshi said Bitcoins should be used as reputation points, then I venture a guess that they would have far lower value. Ripples are not intended to store value. They are intended to facilitate transfer of things with actual value. Therefore, the market will not assign much value to ripples. |

I love bitpay, but this is a really bad thing. Now bitpay has control over how bitcoin will work. I'm not sure if anyone noticed, but what ever the devs put in the code, is whats in everyones bitcoin. It will now be what bitpay wants to see changed, not what the users want, because of course, no one is going to download the latest version from johnjoe who no one knows, over the dev for the past 3 years.
Other than that worry, congrats. I'm curious, are you being paid in bitcoin?
Did you know that Gavin once worked for CoinLab? Did you know he now works for Bitcoin Foundation? Linux development is partially from paid workers for RedHat, SUSE, etc. There's no reason Bitcoin should be different. |

They plan to distribute 50%. If the market would accept them holding 50% I don't know. Satoshi holds nearly 10% currently, so I guess it will come down to personal preference.
Either way. Within the Ripple ecosystem, Ripples are inherently superior to Bitcoins BY DESIGN. That's my point.
I'm not sure how it could be designed so that Ripples weren't superior to bitcoin unless we had a methodology for moving coins across chains, which would be doable, but would require fundamental protocol changes for every coin that wanted to be supported. Why are ripples superior to bitcoins? Like bitcoins, ripples have no underlying value. Unlike bitcoins, nobody is claiming that ripples have value. Put two and two together... As value is determined by markets anyways, it simply makes sense that the market will reject that ripples have any value. |

The gold thing is probably a conspiracy. Physical gold is traded for just as much as paper gold, and little more.

You are not texting, you are typing. Big difference. Translation: 2nd post got flagged. dafuq? I posted a hypothetical, rellevant question about someone s311ing their @ddera11. Why was it removed?
Means My second post has gotten flagged. Why? I posted a hypothetical, rellevant question about someone selling their *unknown translation*. Why was it removed? Now, can you quote the post to see of it violates anything, or the topic was self moderated? Even better: I am oblivious to why my second post was flagged. I had posted a hypothetical and relevant question about someone selling their adderall. Why was it removed?
And the answer to this would be: The forum does not allow posts directly incorporating or linking to illegal activity. |

With this kind of hashing capability, we can already birthday attack MD5/SHA1 fairly easily.  That's rather interesting, actually. Since MD5 is only 128-bit, a hypothetical Bitcoin network on MD5 would have likely found over 2000 collisions by now. Obviously, collisions are not a problem in this context. But it sheds light into just how powerful the Bitcoin network is. That hypothetical Bitcoin network would probably die in the near future from lack of space to adjust difficulty into. Bitcoin is lucky to be using 128-bit cryptography. |

I am working in PHP and I want to check if a given user submitted input is not too big or too small, where the input represents an amount in Bitcoins (don't worry I am sanitising the data and not blindly using it). 1. I am storing the amounts in the database as 64 bit integers (multiply them by 10^8 to avoid rounding errors in future calculations). I am limiting the amounts so that they cannot exceed the following precision: no more than 4 numbers after the decimal point. Also since no-one can have more than 100 million bitcoins, I also want to specify no more than 8 numbers precending the decimal point. How can I achieve this neatly? My current approach seems a bit hack-ish: //Check for existence of decimal point in string using strpos
//explode the string by the decimal point
//do a strlen on both the strings and check they dont exceed 8 and 4 respectively
//if no decimal point, simply do a strelen and check it's not greater than 8
2. Also, I don't want the inputted data to be smaller than 0.0001. I am proficient in php for web design not familiar with the math functions of php is there an easy way to handle this? Thanks for any tips  1&2. Convert the string to float, multiply by 100000000, round, and then take modulo with 10000 or check size. Code below: NB: I don't speak PHP, so this is JavaScript with whatever limited PHP I know. There might be problems with it.<?php
$fStr = 1e8 * floatval($str);
$iStr = round($fStr);
if ($iStr % 10000 != 0) {
// Too many decimal points
} else if ($iStr > 1e16) {
// Too big
} else if ($iStr < 1e4) {
// Too small
}
?>
Warning: You should probably limit the values below 100 million. It is possible for floating-point errors to take over at around that number, and results may be a satoshi off. |

i beg donation. go to college in the united states. need funds for school. i have exhausted my pell grant and am about 1800 dollars short. not sure how is in XBT, but every little donation count. i asked on my facebook and got .00326 donated so far. thanks for any little contribution. Am studying CSE for an associates applied science degree. plan on continuing for a masters and on my way to a MCSE. thank u bitcoiners

i am willing to offer services such as web design and graphic design such as logo's and psds for major donations. thank you
Does your school accept Bitcoin? If not, why don't you beg elsewhere? This community is not any more generous than a random person on the street would be. I feel for you, but this is a case where in-person contributions would be more constructive. Nobody will donate to some stranger on the Internet. |

I, like many others, am sick of all the 'Reputation Threads' flooding the Off-Topic board. It floods the stuff that people actually read there. This is why I propose we make a new Child Board of off topic or find another way to clear up the clutter of the Off Topic Board. Reputation threads sometimes are useful, but sometimes make you suspicious of the person making them. Why stress that you are so trust worthy, and make a whole topic about it? Either this or we find another way to solve this issue.
Another idea I had was each user would have a topic, only listed on their profile for the use of a reputation thread.
Please answer the poll above, and post any Ideas (or just a +1) below!
Best regards,
HeroC
A subboard of "Off-topic" does not make sense. "Off-topic" is, by definition, anything that does not fit anywhere else. |

But it's still probably just an estimate.
My understanding is that it may overshoot or undershoot between blocks (because it doesn't know the exact number, only the average) but the average over all these years should be very close to the real number. And what percent is that number, from all the possible 2^256 SHA256 hashes? That depends on whether or not double-SHA256 is reversible. For our purposes, we can assume it is. If it is, then the chances of a collision is near null and 2 70 is a very miniscule percentage of all possible double-SHA256 results. To be exact, 2 −186. NB: If a function f (x → y) is reversible over a domain D, that means that ∀y∈D ∃x such that f(x) = y. Here we define D to be all numbers between 0 and 2256−1. |

This is Satoshi critics to existing system Bitcoin should be opposite to. They breaking the Bible. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. From one patch to another, Bitcoin becomes what they try to get rid off. hmm... bitcoin BECOMES what they TRY to get rid off BITCOIN becomes what they try to GET RID off bitcoin becomes WHAT they try to GET RID OFF ....no, I still don't understand this phrase its simple: Bitcoin becomes what they try to get rid off. Maybe if of were used right, this phrase would be more understandable. Plus the terminating preposition is annoying. Try this: Bitcoin becomes what it tried to eliminate.

We like to throw these numbers around a lot, but counting the number of downloads of a country is meaningless. What's more important is per capita downloads. I made a chart here below of countries with at least 10000 downloads. | Country | Per capita downloads | Population | Downloads | | Finland | 0.005005 | 5435200 | 27203 | | Sweden | 0.004789 | 9566945 | 45813 | | Netherlands | 0.004454 | 16786100 | 74759 | | Norway | 0.003881 | 5051275 | 19602 | | Canada | 0.003689 | 35056064 | 129327 | | Denmark | 0.003592 | 5602628 | 20124 | | Australia | 0.003488 | 23019264 | 80292 | | New Zealand | 0.003218 | 4466900 | 14375 | | United States | 0.002964 | 315840000 | 936050 | | United Kingdom | 0.002838 | 63181775 | 179301 | | Ireland | 0.002810 | 4585400 | 12885 | | Germany | 0.002533 | 82029000 | 207814 | | Austria | 0.002475 | 8489482 | 21013 | | Switzerland | 0.002465 | 8036900 | 19807 | | Israel | 0.002311 | 8012400 | 18513 | | Slovakia | 0.002254 | 5410836 | 12198 | | Poland | 0.002010 | 38533789 | 77451 | | Bulgaria | 0.001866 | 7282041 | 13590 | | Czech Republic | 0.001790 | 10516125 | 18828 | | Belgium | 0.001766 | 11151495 | 19692 | | Portugal | 0.001435 | 10562178 | 15161 | | Greece | 0.001250 | 10815197 | 13523 | | Russia | 0.001175 | 143369806 | 168512 | | Ukraine | 0.001117 | 45529408 | 50854 | | Hungary | 0.001116 | 9906000 | 11052 | | Romania | 0.001112 | 19043767 | 21172 | | Spain | 0.001021 | 47059533 | 48038 | | France | 0.000825 | 65635000 | 54165 | | Italy | 0.000793 | 59530464 | 47213 | | Argentina | 0.000555 | 40117096 | 22245 | | South Africa | 0.000235 | 51770560 | 12162 | | Brazil | 0.000203 | 193946886 | 39367 | | China | 0.000194 | 1354040000 | 262613 | | Mexico | 0.000136 | 112336538 | 15294 | | India | 0.000018 | 1210193422 | 21776 |

What country are you from? - USA
- Bengladesh
- Honk-Kong
- Tanzania
- Bosnia
- Other countries
The poll should take some sort of reason for listing countries. You could do the largest countries: China, India, USA, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, Japan, Mexico, Other. I guess If you wanted to include Europe better in the poll, you could use the EU as a single entity, it would go between India and the USA. When talking about Bitcoin I think Internet access is pretty significant http://en.wikipedia.org/wiki/List_of_countries_by_number_of_Internet_usersI don't know if it's really that significant, though. Canada is pretty low on the list, but clearly a hub for Bitcoin use. A lot of this is cultural. |

I consider these regulations similar to a bank account. We will eventually have to take them out to fund the network, but that's not necessary now. So we'll earn some interest (the interest being the lack of spam and smaller blockchain sizes) in the meantime.

Here's today's update. As usual, these numbers only reflect BitcoinTalk and so should not be extrapolated to Bitcoin as a whole. §1. Overview20 languages (including the pseudo-language Skandinavisk) were enumerated at approximately UTC 0:00 for the past 6 days. These languages seem to be the only ones featuring greater than 100 posts on BitcoinTalk. 1287 posts could not be established as being of a particular language, and so were not enumerated. §2. Trends §3. AnalysisAs usual, languages can be split into 3 distinct categories. One category, the high-volume languages contains English exclusively. The second, the medium-volume languages, contains most of the languages with their own subforum. The final category, the low-volume languages, consists of Greek, Hebrew, Korean, and the Other language threads. High-volume languages are uneventful as usual. English, as a mature language, displays stable growth. Medium-volume languages are most spread out of any category. The spread seems to be decreasing, however, as Dutch grows faster than Russian (in relative terms). Dutch is gaining ground on Skandinavisk, and may pass it soon. By far most eventful, however, remains the rapid growth of Chinese. Although relative growth has stalled yesterday, absolute growth remains second to only English. The Chinese subforum has grown almost 50% in the past 6 days, likely driven by news reports in the Chinese mainland. The gap between Chinese and Portuguese, although still large, is shrinking. Low-volume languages are spread over an extremely narrow range. As usual, these languages display extremely erratic growth. Greek has recently shown rapid growth, likely accelerated yesterday by its promotion from thread to subforum. It is now comfortably ahead of a stalling Turkish thread. Greek's growth is most readily attributed to its new subforum. Also of note is Polish, a threaded language, which yesterday exceeded Korean, a language with a subforum. §4. RemarksIt will be interesting to watch the continued growth of Chinese and Greek. In terms of activity, measured by the absolute increase in posts for the last 6 days, Chinese is now second only to English. Greek activity is also on the rise, with more posts in the last 6 days than Skandinavisk. Some boards are stalling, likely due to low populations of speakers. Despite being 4 times larger, the Italian board has seen less activity than Romanian in the last 6 days. Similarly, Skandinavisk has been growing slower than Greek—surprising, given that it is almost 10 times as big. §5. AppendixWith 6 days of data, it is now possible to create a pie chart on posts made in the past 6 days only. This is demonstrative of the activity levels of a board. These data are important for considering how many moderators should be assigned to a particular board.  |
