Have you tried the "ignore" function?  With some discipline, I am able to remove low-IQ contributors, whilst keeping most of those who have something to contribute - even if I totally disagree with it.

I just learned a Russia Today reporter promotes bitcoin, which answers the title question IMO.
Now you are starting to sound like idiots you were criticizing.

I followed RT on Facebook for a couple of year, because I am critical of Israeli and American foreign policy and consider myself a type of anti-Zionist but I was shocked by the outrageous anti semitism shown by so many of the commenters: I have never seen so many anti-Semites commenting in one place. Perhaps it is something to do with Russian society, or just that crazies always tend to intermingle with thoughtful dissidents (which is what happened at occupy in my city).

TLDR: a lot of racist people happen to like RT.
I may have missed it. I thought you were referring to the RT journalists, but sounds like it's the commentators. I never looked at the comments, just watch RT occasionally.

If he isn't right, then Bitcoin is destined to go up in a mushroom cloud.

why?

Bitcoiners tend to be enthusiasts who forget what a minority fringe phenomena that Bitcoin still is and tend to over estimate the present day significance of the coin. This is why so much drivel about the fundamentals pushing up the price during the recent bull run was disseminated and widely consumed on this forum and no doubt across the Bitcoin world.

Relatively few could recognise that a classic speculative bubble was what was actually happening, and quite probably, a bubble that was being manipulated into existence.

Yet that is what it was. If that is all that Bitcoin is to be in the future then Bitcoin will never develop any substance and will sooner rather than later, fail.

Mass investment psychology will ultimately be the kiss of death on any stock or intangible asset that isn't based on anything or forcibly held in place by some powerful third party.

Bitcoin needs real businesses and real people en masse, trading goods and services, and transferring wealth to each other, using Bitcoin. In recent times, Bitcoin couldnt be less appealing to anyone with anything other in mind than pure profit seeking speculation.

Too much speculation on any asset is a parasite on the organism which will ultimately kill it.
This is the best post I've read in many days.

Hey people, I really want to understand this, but you're ahead of me.  I need this to be explained like I'm a 5 year old.

I am familiar with the wallet.dat file.  It's an object, a FILE, that I protect.  But I do not understand where, when, or how I extract a "private key".  Nor do I understand how the private key relates to blockchain.info.  

Can someone explain this stuff or give me a link?  

I've been waxing on to my friends about bitcoin, but when we get to wallet security enthusiasm wanes.

Thanks.

Private key is a random number (may be expressed as a string of random characters, of course). It is private because, presumably, only the person who created it knows it. Note, "random" can be anything (with some technical limitations), including, for example, a hash of a sentence. This is convenient if you wish to store private keys in your brain.

Public key is calculated from the priv key using the ECDSA. Note, this is a one-way function: calculating the publoc key from the private key is easy, finding out the priv key when a public key is known is practically impossible.

Bitcoin address is calculated as a one-way function of the public key. Specifically, it is a double hash of pub key, ripemd160(sha256(pubkey)).

To spend (send) coins currently associated with a given address, your client (wallet program) signs a message about the spend from the corresponding public key, and message is signed with the corresponding private key. Note, the way digital signature works is that anyone who knows the public key can check that the signature was made using the valid private key, without knowing the private key. All nodes in the network can then verify that the message is valid, and broadcast it further. Eventually, a mining node will create a new block (every 10 minutes on average), and include this message ("spend") into this block, thus making it official. Note, you can only spend the complete amount of coins associated with an address. If what you are sending is less than that, the rest goes to a new address of yours. Your total balance is still correct, of course.

What your wallet software (bitcoin-qt client, multibit, or any online wallet service) does is it creates key pairs for you, manages them, and checks balances associated with the keys/addresses you own (typically only showing you the total).

===================

Most clients will let you export ("dump") private keys. Refer to the documentation about the particular client you're using. You can then preserve private key(s) using any method discussed here. Most people print them out ("paper wallets").

You can keep the physical embodiments of your private keys hidden and secure, or you can encrypt the keys beforehand, or both. Note, bitcoin-qt client offers encryption of private keys in your wallet.dat.

I suggest everyone should immediately quit discussing strategies and legal options in this public thread. Communicate via email/skype/in person, and even then make sure you are not communicating with Ian's puppet accounts.

As I already pointed out, I have no stake in this matter anymore. The reason I sold out and quit dealing with Bakewell was that I decided not to waste any more time or money on him. This is still so.

I am sorry for those of you who have not seen things the same way, and continued dealing with him. I wish you best of luck recovering your belongings. In case any of you decide to report this matter, a good place to start is

Ian, if you read this thread - read it again.

I'm stupid...where are you monitoring lag at?

You can see it on most live charts like ClarkMoody's or Bitcoinity.
In addition, this is the call to check it yourself: https://data.mtgox.com/api/1/generic/order/lag

Great thread OP.

Put your money where your mouth is, and make a bet on the price.

I will bet 1 BTC that MtGox USD is over $100 7 days from now.

In 7 days? I don't disagree with you.

Tomorrow? Let's see what happens.

it's at 103 USD atm.

Below 100 atm. Everything is going to plan. Bull trap activated, prepare for freefall.

Play nice! Don't be making fun of BFL's workforce. They're special!



Don't laugh. Computing hashes can be done like shown in the picture.

Soon, a game will be developed to rival Angry Birds, cleverly dubbed Bust My Balls.

Off the top of my head:

Player one has a tiny ball on their screen, the size of which they can barely see. Upon turning it on, it creates a new ball of which is numbered, in this case it is number 1. Number 1 ball leaves the screens to travel eventually appearing on somebody else's screen who has their own ball showing. The goal is to get a visiting numbered ball to hit your ball so that it can grow in size.

The larger your ball is, the better the odds of having it make contact with a visiting ball. The closer the people are who simply have the app on their smartphones, the more numbers balls will enter your domain.

You're only allowed to send out one ball per day, unless... (still thinking on this)

Since numbered 1 is the first and will be in the wild the longest, it would most likely make the most contacts. Each time it does such, it travels faster through the system, interacting with more users. This does not mean it travels faster across your screen. It's always at the same pace allowing you time to make contact with it. It can only be on one screen at a time.

A website can be created to show what numbered balls you have made contact with, alone with keeping a tally.

Just figured it out: As you level up, you'll be able to send out more numbered balls per day. You also gain points as your created balls make contact.

Further thinking: Assign one satoshi to each created numbered ball. Design the game so that it is very easy to play, but there's a monetary reward each time your created balls make contact. The more balls you create, the potentially more money you can earn, albeit it's only satoshis--at first.

Somebody will have to create and maintain the BallChain to keep track of the contacts/transactions.

And players can purchase access to the big picture: the more they pay, the wider field of view - so they see what's coming, how many players are nearby. You pay to expand your horizon, and thus anticipate, plan, and position yourself better.

No, he is not making a profit. Only if he sells coins at that price, he will be making a USD profit.
493  Economy / Speculation / Re: The Crash Then and Now - 2011 v 2013 how big are the differences? on: April 13, 2013, 02:48:45 PM
just plot it on a log sale and you can compare directly, thats what log scale was made for.

Yes. A percent scale would also be alright. Since we are only looking at ~10x change in price within the time span of interest, linear scale is not too badly distorted compared to the (more appropriate) log scale.

Sounds good to me. Don't obsess over how much you would get this hour or the next if you sold or bought your coins. Look at what is, not what would have or should have been.
You've got your 2.5 coins. Great.

How about make a plan? when price hits X, I'll sell Y coins. When price drops to P, I'll by Q coins, assuming fundamentals still seem good to me.

If I need cash urgently, I'll sell coins no matter what. I won't waste time calculating how much I would have gotten had I sold them yesterday instead. I didn't, so it's pointless.

How about using bitcoins instead of just investing? Would that work for me? Do I have a need for fast, cheap international payments and transfers? Can I offer work/expertise/products for bitcoins?

Etc.

Introduction: Hash functions are computer algorithms that protect information and secure transactions. In response to the NIST’s "International Call for Hash Function”, we developed a biological hash function using the computing capabilities of bacteria. We designed a DNA-based XOR logic gate that allows bacterial colonies arranged in a series on an agar plate to perform hash function calculations. 

Results and Discussion: In order to provide each colony with adequate time to process inputs and perform XOR logic, we designed and successfully demonstrated a system for time-delayed bacterial growth. Our system is based on the diffusion of ß-lactamase, resulting in destruction of ampicillin. Our DNA-based XOR logic gate design is based on the opposition of two promoters. Our results showed that Plux and POmpC functioned as expected individually, but Plux did not behave as expected in the XOR construct. Our data showed that, contrary to literature reports, the Plux promoter is bidirectional. In the absence of the 3OC6 inducer, the LuxR activator can bind to the Plux promoter and induce backwards transcription. 

Conclusion and Prospects: Our system of time delayed bacterial growth allows for the successive processing of a bacterial hash function, and is expected to have utility in other synthetic biology applications. While testing our DNA-based XOR logic gate, we uncovered a novel function of Plux. In the absence of autoinducer 3OC6, LuxR binds to Plux and activates backwards transcription. This result advances basic research and has important implications for the widespread use of the Plux promoter.
