According to blockchain.info, the block 210000 was solved on 2012-11-28 15:24:38 GMT, and was relayed by Slush's Pool. The pool's Stats page also claims to have solved that block. It has also been stated that the block was solved by pool's user by the nickname of laughingbear.
Short answer: 4 [Prior to the March 12, 2013 fork]
The Value Overflow incident seems to be the longest ever blockchain split. The problem with blockchain forks is that once they are resolved the only trace they leave is a log entry.
To reconstruct the following I used the printblocktree output that theymos gave me in this question and the information from ...
Script was in the first version of Bitcoin. Satoshi developed Bitcoin in private before releasing the fully-usable Bitcoin 0.1, and he said very little about his thought-process, so we'll probably never know exactly why many things were done the way they were.
Script had several serious bugs when Bitcoin was first released, and some bugs still exist. It's ...
The March 12, 2013 blockchain fork started with 225430 and so far has reached block 225461, so it is 31 blocks long. Some of those were mined long after the fork supported by v0.7 clients had regained longest chain. At the peak the fork which supported by v0.8 clients was at least a dozen blocks higher meaning transactions that had more than ten ...
I've got an answer on Reddit:
It's likely to have been written in a PM or an email to some developers, and it seems that Mike Hearn (BitcoinJ) was the one who published this statement:
Mike Hearn - February 25, 2013, 12:48:54 PM
He communicated with a few of the core developers before leaving. He
told myself and Gavin that he had moved on to other ...
The "Linode problem" is storing Bitcoins on a managed device. That managed device might be server hosting from Linode, for example, or a cloud server at RackSpace for another example. In both instances, by simply gaining root access using the service provider's systems, tens of thousands of bitcoins were stolen.
The incident in which the "Linode problem" ...
The current testnet is on its third iteration, somewhat unimaginatively titled testnet3.
It was put that way by this commit:

According to Bitcoin and Cryptocurrency Technologies (BaCT), the Princeton Bitcoin textbook, the block chain dates back to a "paper by Haber and Stornetta in 1991. Their proposal was a method for secure timestamping of digitaldocuments, rather than a digital money scheme." (BaCT p.15)
The chaining of Merkle trees instead of single documents was proposed in ...
Pay to Public Key Hash has existed for the entirety of Bitcoin's life. P2PKH addresses have existed since the earliest release of Bitcoin. Creating P2PKH addresses and sending to P2PKH addresses was possible to do with Bitcoin 0.1.0.
However these early versions of Bitcoin also supported a Pay to IP address feature where your wallet would contact the ...
Yes - it's feasible.
Bitcoins are released at a constant rate determined by the protocol. At the time, 50 Bitcoins were being generated for every block(this is now 25); and blocks are supposed to be found every 10 minutes. Miners compete amongst each other for this prize.
In 2009, you could mine using your computer's CPU and you were only competing with ...
This is a known bug in the early days of bitcoin.
Was fixed by BIP-30 https://github.com/bitcoin/bips/blob/master/bip-0030.mediawiki
There is a discussion here: https://bitcointalk.org/index.php?topic=216938
And yes, 50+50 bitcoins are missed forever.
In fact, there are much more missed bitcoins. For example, 2500 bitcoins were gone to nowhere
in block ...
Have a look at the early sources here: http://www.bitcointrading.com/forum/bitcoin-clients/original-bitcoin-source-code-archives/
there is a small piece of code in script.cpp:

which allows to spend ANY UTXO with just a very simple scriptSig OP_1 OP_RETURN
Bitcoin Pizza Day is celebrated on May 22nd. On this day in 2010, a BitcoinTalk member bought pizza in exchange for 10,000 BTC. This represents more or less the first known transaction using bitcoins for actual goods.

The very first icon (created by Satoshi) is visible here:
Satoshi later updated this using the B with two vertical strokes
He never posted much about why he chose this symbol. It was not in use before Satoshi put it in the logo.
This is what I see for a search on pgp.mit.eud, which points to this key:
That is a surprising result. If we download the key purported to be Nakamoto's from Bitcoin.org, we get the following fingerprint:

According to the mailing list archives, the mailing list received Satoshi's email at Fri Oct 31 14:10:00 EDT 2008. However the mailing list is moderated so perhaps the email was not received by everyone until a day later on November 1st. The first response to the email was sent on November 2nd, so it may be that the email was not forwarded to the list for a ...
Litecoin was not the first altcoin. It actually uses ideas for altcoins that precede it but had died before it was created. This is mentioned in its announcement thread on bitcointalk.. The very first altcoin was actually Namecoin, announced in April 2011. Namecoin was actively used and mined, and can still be used today.

The first non-coinbase transaction in the chain is in block 170. Not sure what you would consider a 'real' versus a 'test' transaction, but given that there is an entirely separate blockchain for test transactions I'd consider it as real as any other.
I'll list the mentions I've found in reverse chronological order.
It first showed up on StackExchange on August 30, 2011.
However, I often hear the term Satoshi as if it was a monetary unit.

I'll use the term "Satoshi", as previously coined by others, to mean the current smallest ...
This is not true. Code and code comments in v0.1.5 (the oldest tagged version in git) enforce that there always is a coinbase transaction and that it must always be the first. There cannot be a coinbase transaction elsewhere in the block. Coinbase transactions are defined as transactions with one input whose previous transaction hash is all 0's and whose ...
It depends on how you define release.
Satoshi sent the email to the Cryptography mailing list on Jan 8 2009 UTC. However because the Cryptography mailing list is moderated, that email did not reach email subscribers until Jan 9 or 10 2009 (it's actually Jan 10 2009 at 1 AM UTC).
The discrepancy you see is that many people refer to The Mail Archive source. ...
According to MtGox, the hacker got about 2000 BTC. A few real customers also appear to have purchased bitcoins at an artificially low price during the incident, withdrawn them, and kept them. This is estimated to amount to less than 650 BTC.
The details given at the above link are:

In order of date:
13th June 2011, 25,000 BTC stolen from an early adopter "allinvain": A single user claims they were hacked and lost an enormous quantity of Bitcoins.
15th June 2011, 650 (?) BTC stolen from MtGox exchange: This attack probably made the news more than any other because the apparent market price plunged to $0.01/BTC, but withdrawal limits ...
This post from SmokesTooMuch seems to be the first time GPU mining was suggested:
Since the coins are generated faster on fast machines, many people will want to use their GPU power to do this, too.
So, my suggestion is to implement a GPU-computing support using ATI Stream and Nvidia CUDA.

This much less likely for a number of reasons:
Banks have advanced, robust and well-tested anti-fraud infrastructure, making such thefts much more likely to be detected.
Legally it is much much easier to prosecute for fraud cases in fiat than BTC (I do not know any prosecution over stolen Bitcoins)
Fiat transactions are reversible meaning the exchange could ...
