Therefore, the export control determination has to be made by the project’s registered administrator on SourceForge, which for Bitcoin is lead developer Gavin Andresen

Well, I imagine Matonis is a little conflicted at this point, given that he is sitting on the board of The Bitcoin Foundation alongside the chief dev who has blocked Iranians from downloading the software .... seems like there might be a case for a hidden service on Tor mirroring bitcoin "official" repo.
The developers don't have a choice. Bitcoin uses strong cryptography, which, for reasons which don't really make sense, is legally classified as a military weapon under the Wassenaar Arrangement, and therefore illegal to export to "certain" countries. Simply making the source code available for download worldwide is legally equivilant to selling bombs to Iran. As fucked up as the law is, it must be obeyed if you want to avoid being jailed for arms trafficking.

Warning: Moderators do not remove likely scams. You must use your own brain: caveat emptor. Watch out for Ponzi schemes. Do not invest more than you can afford to lose.

The first line in the disclaimer shows how complicit the moderator's are in the criminal acts performed on this forum.
No it doesn't, for the reasons I already explained. It's not even a disclaimer in any case: where does it even say that anyone is disclaiming liability of anything? It's just a warning and a reminder that brain use is required. Normally such warnings would not be required, but since we're potentially dealing with the same people who apparently can't drink coffee without burning themselves and then suing everyone who didn't warn them that hot things can cause burns, it pays to play it safe and just include stupid warnings for stupid people.

In the eyes of the law, this makes them conspirators. Not to mention this forum could face penalties under the RICO act for protecting and promoting the criminals that fill the lending and securities forum.
Warning people about potential scams makes one a conspirator in the eyes of the law? What crazy law are you talking about here? And you've got a long way to go if you think that simply refusing to censor lawful communications based on unproven accusations of unlawfulness counts as racketeering.

Exactly which politicians are pushing for Bitcoin to "open up its data", and do they realise how silly they look when not only is all the data (both the code and the transaction database) already completely open to "close government scrutiny", but being so open to scrutiny is precisely the entire point of Bitcoin (since that's how it prevents fraud without relying on trusted third parties)?

Bitcoin banks? Does he mean the exchanges?
No. He's talking about the MyBitcoin fiasco. Though, he's got a lot of other things confused:

Quote
When Bitcoin was launched in 2008, each Bitcoin traded at three US cents each;
Quote
With such a tempting rate, many people piled in – as many as 500,000 Bitcoins were sent to Pirate, giving a value before interest of almost $7 million entering Bitcoin Savings and trust.

The allegation that Pirate was running a Ponzi scheme dropped the value of the currency by almost 30 per cent.

3965  Bitcoin / Development & Technical Discussion / Re: Dropdown of Current Label/Addresses on: October 08, 2012, 11:09:23 AM
This is already implemented. In the Transactions tab, type the address you're interested in (or it's label) into the search bar, then click Export. Open the resulting file in your spreadsheet software. You now have a list of all transactions associated with that specific address in spreadsheet form, ready for you to calculate totals, copy part or all of it into another spreadsheet, or whatever else you want to do with it.

Yes, people get scammed with anything of value. Sane communities try to stop the scammers; this community actively promotes them and allows them to thrive.

Look at the disclaimer over the lending forum and tell me this forum doesn't promote scammers.
It doesn't. Anything which can be proven to be a scam is deleted on sight (though this is rarely noticed as nobody except moderators can see deleted threads). Moderators do not (and should not) delete things which are "likely" to be a scam when there's no real proof, to avoid inadvertently ruining the reputation of honest borrowers. People are considered innocent until proven guilty.
3967  Economy / Scam Accusations / Re: Butterflylabs Huge SCAM on: October 07, 2012, 06:15:54 AM
I said it was a scam as well, but forum moderator "psy" saw it fit to delete my post.  Seems to go in line with this forums policy to protect and promote scans.
Do you have proof that it's a scam? Remember, they've already delivered on their FPGAs, as promised, and they function as advertised, so they would seem to be a legitimate company, albeit one with extremely poor customer service. You can't just accuse a legitimate company of being a huge scam without evidence. You can say it might be scam, and you can list reasons why it's probably a scam, but you can't outright say it is a scam unless you have damn good evidence to support your claim.

Funny how the whole libertarian freedom thing goes out the window once you go against the moderator's personal veiws.
You clearly have absolutely no understanding of freedom, in particular freedom of association. Freedom of association means that if a private association has certain rules, and you voluntarily agree to those rules in order to join said association, then the association's leaders have the freedom to punish you if you break the rules you agreed to. If you disagree with the rules, you have the freedom to leave and form your own association, with your own rules. You do not have the freedom to make accusations without any supporting evidence when this is against the rules you voluntarily agreed to.

https://bitcointalk.org/index.php?topic=83794.0

Is this acceptable to the community? (To be clear, this is an incomplete list as far as I can tell)

How much money needs to be stolen before the community accepts that there is a problem?  Some of you get it, others still want to be part of the problem, apparently.
Bitcoins (along with gold, and dollars, and many other things) are valuable. Criminals try to steal, embezzle, or otherwise fraudulently obtain things that are valuable. Sometimes they succeed. This isn't a problem with Bitcoin, or the Bitcoin community (or gold or dollars for that matter). It's just a fact of life. If you really are an SEC agent, you would know that already, and you would also know that it's your job to make some attempt to actually investigate these crimes instead of just complaining about them, since most of us here are mere private citizens who have neither the authority nor the ability to do so.
3969  Other / Beginners & Help / Re: Bitcoin scams on: October 07, 2012, 03:12:25 AM
Cant tell, FUD or Micon with a new strategy.
There is also a third option: an actual SEC agent who's never used the Internet before, and while he probably learnt in his training that scams of various kinds are prevalent on the Internet, he hasn't the faintest idea of just how prevalent they are, and the impossibility of getting rid of them without outright banning discussion of any business proposals of any kind (which obviously isn't an acceptable solution on a forum about Internet currency). Hell, I've seen scams advertised on well-moderated furry porn sites ffs; the very idea that all scams can be eliminated from a site devoted to money represents a ludicrous level of wishful thinking.

That said, I tend to stay away from the lending forum for exactly this reason. What exactly goes through people's heads when they're told "Please irreversibly transfer your money to my anonymous account. I'll pay you back. Honest."? I mean, seriously, stuff like this makes you wonder how a fool and his money ever got together in the first place.

The number of Bitcoins generated per block starts at 50 and is halved every 210,000 blocks (about four years).

I heard another "halving" will start in December.
It's not another halving, or a special one, it's just the first (regular) halving. Block number 210,000 is expected to be mined sometime in December of this year (which is just under four years after the Bitcoin network became operational).

I began visiting this forum a few months ago, and since I have been here I have been baffled by the proliferation of banking and security scams and frauds. Every "business" I have looked at has been nothing more than a poorly hidden scheme to seperate fools from their money.
What, every one? Look harder.

So, why do you think scams are operated so freely here? Lack of moderation on the forum? A community to greedy to care? Is it just the anonymity and the (until recently) lack of punishment and law enforcement?
If you look past the obvious answers, you'll see one that's even more obvious. Specifically, there are scams everywhere. These forums actually have relatively few scams, at least when compared to the rest of the Internet, or even just my spam folder.

Why shouldn't the forums (and bitcoin overall) be shut down?
Go shut down the U.S. Dollar. It's involved in far larger and far more numerous scams and illegal transactions than Bitcoin ever has.

Why shouldn't a central authority be set up to tackle the frauds that are so endemic in this community?
We already have one. It was established long ago as a government agency, a commission if you will, in charge of regulating the exchange of things like securities and other investments. I just can't remember what it's called. The Commission of Exchange of Securities? No, that's not it... Oh wait, I remember now, it's called the Securities and Exchange Commission. You may have heard of it. Why aren't they doing something about all this?
3972  Economy / Speculation / Re: Is Bitcoin Going to the moon? on: October 06, 2012, 12:22:18 AM
Of course not. The light-speed delay will mean more stale blocks. Although non-mining nodes may go to the Moon, all the hashing action is going to remain on Earth until the InterplanetartyCoin fork (with day-long confirmation times) gains acceptance.

You're right, but to be fair, you could have chosen your words better. I mean, what about all the women without vaginas, did you ever think about their feelings? You really should have said "humanoids without a Y chromosome". No wait, that doesn't work in all cases either (eg those with Swyer syndrome or de la Chapelle syndrome). You know what, how about we just forget about classifying individuals based solely on the appearance of their genitalia and instead just call them all "people" and treat them all equally?
3974  Other / Off-topic / Re: Did NSA Put a Secret Backdoor in New Encryption Standard? on: October 03, 2012, 08:38:07 AM
So there is a backdoor, and you know what it is?   Grin
There definitely exists a "magic number" which allows whoever knows the magic number along with 32 bytes of the PRNG output to completely predict the rest of the output. The algorithm designer may (or may not) have had a specific magic number in mind when designing this algorithm. If so, it's a backdoor. If not, it's not (but there's no way to know for sure). Consider also that this algorithm is about a thousand times slower than other PRNGs and produces random numbers with a slight bias, making it an extremely poor choice even if it doesn't have a backdoor. The only reason I can think of for the NSA to endorse such an obviously flawed algorithm is that it's the only one they were able to get a backdoor into. What other explanation is there?
3975  Bitcoin / Bitcoin Discussion / Re: "All cryptography is breakable" criticism on: October 03, 2012, 07:38:41 AM
I apologize if this has been asked here already and I missed it (it seems obvious) - are there recent examples of cryptographic algorithms being broken in a sudden, catastrophic fashion? I see it much more likely that a "weakness" is published first, thus giving everyone some time to migrate to a new signature algo and send their coins to the new system.
I don't think this has ever happened to any reputable modern algorithm (someone please correct me if I'm wrong). All now-broken cryptographic algorithms that I know of were widely known to be broken long before an actual attack was successfully demonstrated.

How hard would it be technically to enable spending of "old" ECDSA coins into the network based on a different signing algorithm?
Of course it's possible to send "old algorithm" coins to an "new algorithm" address. It's already happening: compressed public keys technically function as a new algorithm, even though it's all ECDSA.
3976  Other / Off-topic / Re: Basic encryption questions on: October 02, 2012, 08:22:01 PM
If I encode a message with an RSA public key and then transmit it over a completely insecure network, is it possible for an attacker to see that the receiver (known by the public key) received a message?
Yes. That's the whole point of using encryption in the first place: for those situations where you know (or at least suspect) that an eavesdropper will see all your messages, but you want the eavesdropper to be unable to determine the content of the messages that they see. If you need to prevent an attacker from knowing a message was sent at all, encryption won't help; you need to use other techniques to hide your messages, such as steganography.

Is the answer different for ECDSA? Is it different for other public key algorithms?
No, as that's not what encryption does or is supposed to do.

Next question:
I remember reading something about ECC having a property where one could extract the public key from some other piece of information efficiently and that Satoshi wasn't aware of this property. Could someone remind me of this property?
I have no idea what you're talking about. Wait - extract the public key efficiently? How is that even a problem?
3977  Other / Off-topic / Re: Did NSA Put a Secret Backdoor in New Encryption Standard? on: October 02, 2012, 08:03:09 PM
The headline is misleading, as Dual_EC_DRBG is a pseudo-random number generator, not an encryption standard.

Anything to worry about?
Only if you use Dual_EC_DRBG. Bitcoin doesn't use it, or any other PRNG for that matter, instead relying on the OS's entropy source, which (normally) produces random numbers from hardware sources. Note that ECDSA (which Bitcoin does use) is not related to Dual_EC_DRBG in any way other than being based on the elliptic curve discrete logarithm problem, and does not have this backdoor.

And why make it a one-timer? Polymer frames are a reality today.
Polymer frames are easy. Designing polymer barrels that don't instantly disintegrate from the combination of heat, pressure, and friction is a slightly harder engineering challenge.
3979  Other / Beginners & Help / Re: How to determine the sender? on: September 26, 2012, 07:35:31 AM
They're just addresses, they don't "want" anything. More to the point, A, B, and C are addresses that belong to either the same person (who probably doesn't even know or care about individual addresses in the same way that a person using cash doesn't bother keeping track of individual coins and notes), or (though this is far less likely) multiple people acting jointly as a single entity (in which case there is no way to tell what each individual was thinking, other than that they were all in complete agreement as to how the money was to be distributed - exactly how they came to that agreement is their own business and no-one else's).
3980  Other / Beginners & Help / Re: How to determine the sender? on: September 25, 2012, 07:30:10 PM
The first link is an example showing trasaction from multiple senders and at most two receivers ( refering from Ch 9 in orginal bitcoin paper).
Suppose we have a transaction as A and B and C send total amount of 5 bitcoins to D and E. From the transaction, we can tell how many
bitcoins sent by A or B or C and how many received by D or E. But how can we tell how many bitcoins sent from A to D?
A, B, and C are almost certainly different addresses in the same wallet, and belong to one person. But in case you're wondering, clicking "Show scripts & coinbase" in blockchain.info will show you exactly how much came from each address.

The second link is an example of transaction from single sender to multiple receivers(more than 2) which is not shown in origianl paper.
Is this introduced by newer version in bitcoin?
No, this has always been around. In fact, it's pretty rare to find a transaction that doesn't send to two or more addresses, since transactions usually have to make change.

Both of these situations are explained in Chapter 9 of the whitepaper. Note that there's actually no limit on the number of outputs, and although a transaction from one person to another will normally only have two outputs, it is possible to use more than two outputs, for example when sending to multiple people with one transaction. The whitepaper only provides examples of the most common situation.
