Jeff Garzik

Jeff Garzik, Co-Founder of Bloq Inc, was a contributor to Bitcoin Core before and including 2015.
Garzik was a participant in the SegWit2x debacle. At one point, Garzik was against raising the block size.I am against changing block size, FWIW. I think the market will properly intervene, bitcoin will reach a steady state where all blocks are 1MB, and the best bidding gets block placement." also "IMO I think the current bitcoin's endgame is as a not-high-volume settlement network.

Jercos

Jeremy Sturdivant (jercos) was the counter-party to Laszlo Hanyecz in the first documented purchase of a tangible good or service using bitcoin. On May 22, 2010 Laszlo Hanyecz famously declared success in his four day quest to trade 10,000 BTC for “a couple of pizzas”, posting on a bitcointalk forum page:
 
“I just want to report that I successfully traded 10,000 bitcoins for pizza.
Thanks jercos!”
According to jercos the transaction was finalized over IRC chats.
Jercos was 18 at the time of the transaction. 
At one time in late 2013 10,000 bitcoins was worth over USD$12million.

July 2015 flood attack

The July 2015 flood attack was a large "stress test" of the Bitcoin network. The possibly distributed attack has provoked hundreds of thousands of transactions, leaving over 80,000 in the mempool at one time. The attack is subsequent to stress tests executed in June.
Some charities and organizations, including WikiLeaks and Voat, have received thousands of dust outputs. Additionally, some single-word brainwallets ("password", "cat", etc.) have been the recipients of thousands of transactions, leaving 0.00001 BTC outputs. F2Pool has been concatenating these outputs in huge 1MB transactions. These transactions fill up an entire block on their own, and are far too large to be relayed by nodes; they have only been confirmed because F2Pool dedicated blocks to them. Some nodes reported having spent over 20 seconds verifying one of these transactions, explaining momentary but extreme latency and downtime on block chain explorers.
Gregory Maxwell later contacted F2Pool, advising them to use the same signature for each input in the large transactions. This made the transactions highly compressible and far easier to verify.
As a result of this attack, most mining pools updated their software to produce 1 MB blocks, as originally most capped their blocks at sizes such as 250 kB or 750 kB. The attack seems to have concluded by July 15.
==Motivation==
The attackers may have had an agenda related to the blocksize debate, attempting to demonstrate the infeasibility of 1MB blocks including transactions of hundreds of thousands of users. Specifically, the Chinese mining pools (AntPool, BW Mining, F2Pool, BTC China, & Huobi) have expressed distaste towards Gavin Andresen's proposals to increase the blocksize limit, citing concerns of relatively low bandwidth compared to that available in the United States and Europe. The flood attack may have been attempting to discredit the pools, and subsequently force them off the network after the raised blocksize limit is in effect.
It is unlikely that the attack was used in an attempt to damage or shut down Bitcoin, as it appears to have been controlled and benevolent. It has also resulted in the donation of over 30 BTC to various sites.
==Suspects==
Coinwallet.eu, who had executed the previous stress tests, may have something to do with this attack as one of their bitcoin addresses had been used in both efforts. However, Coinwallet.eu did not announce involvement in this attack, as they had in the stress tests.
Peter Todd had previously offered to execute a stress test for $7,000 but he denies involvement in this attack.
A redditor has published the private keys to hundreds of addresses which have been recipients of dust outputs in 2013, perhaps in an attempt to incite additional spam as redditors try to claim the funds.
Satoshi Nakamoto has been (perhaps jokingly) labeled a suspect, as he had mentioned that the block size should be increased when it is needed and may be campaigning for this change without revealing his involvement.

KnCMinerOverclocking

=== Overview ===
The KnC Miner hardware runs as a BeagleBoard controlling a number of ASIC modules. Each of the ASIC modules has 4 or 8 "dies". During the starting of the miner the clock rate of the ASICs is set via the SPI protocol to each die. Therefore we can adjust the clock rate of each die to find a good balance for each miner.
The BeagleBoard is running a minimal Linux operating system. You'll need to understand a bit about ssh, bash and maybe scp in order to achieve an over-clock.
=== Model Differences ===
The October released miners have the "easiest" firmware to modify, the commands to set the speed of the dies is located within /etc/init.d/cgminer.
With the November miners we'll need to add similar code to perform the setting of the clock rate.
=== Frequency Values ===

=== Over-clocking Guide ===
# Determine miner model
# Setup SSH access to miner
# Install bgminer
# Update /etc/init.d scripts to use bgminer
# Setup method to monitor temps/current/voltage/wattage
# Update init.d scripts with new clock rate
# Restart bfgminer
# Monitor temps/etc
# If performing badly or temps/draw very high stop mining go back to 6
# Profit!
Krad Miner

Krad Miner is a Firefox 4 extension that uses WebCL and the video card (GPU) to mine bitcoins. According to its home page Krad Miner is "1,000 - 30,000 times faster than a Javascript based Bitcoin miner".
As of June 22, 2011 a statement left on http://kradminer.com indicates that due to denial of service attacks and other mischief krad miner will be shutting down. The author goes on to state that he wrote the software in about 5 days and had intended to open source the software. However no one he spoke to was willing to purchase the software rights for the price of 50btc, the reasoning for not opening the codebase is vague and uncertain. 
"So unless a better offer comes along I have no intention to release this specific code, since it will likely just be used for pathetic rip off sites." - quote from krad miner
On Sept 4th, 2011 someone posted a query to the the bitcoin stackexchange wondering what happened to Krad Miner. 
On June 3rd, 2012 user temujin9 answered that he had purchased the code from Krad for 50 btc in order to open source it. Temujin9 has renamed Krad Miner as Tumen Miner and published the source code on his github account.

Labcoin

labcoin was purportedly a company run by iTec Pro Limited which made claims to several ASIC hardware developments and sought investment by common members of the public.
Many of its claims were refuted and media released was claimed to have been manipulated or be of infeasible design for the claims. By the 5th of November, some of the investors made claims to begin a lawsuit against the people involved in what they believe to have been a scam.
