Eric Brewer (scientist) Eric A. Brewer is the main inventor of a wireless networking scheme called WiLDNet which promises to bring low-cost connectivity to rural areas of the developing world. He was made a tenured professor at UC Berkeley. In 1996, Brewer co-founded Inktomi Corporation. He is known for formulating the CAP Theorem about distributed network applications.[1] He is currently on a sabbatical at Google.[2] Brewer received a BS in Electrical Engineering and Computer Science (EECS) from UC Berkeley where he was a member of the Pi Lambda Phi fraternity.[3] Later he earned an MS and PhD in EECS from MIT.
In 1999, he was named to the MIT Technology Review TR100 as one of the top 100 innovators in the world under the age of 35.[4] Brewer is the 2009 recipient[5] of the ACM-Infosys Foundation Award in the Computing Sciences[6] "for his contributions to the design and development of highly scalable Internet services. " In 2013, the ETH Zurich honored him with the title Dr. sc. tech. Brewer's CAP Theorem. On Friday 4th June 1976, in a small upstairs room away from the main concert auditorium, the Sex Pistols kicked off their first gig at Manchester’s Lesser Free Trade Hall.
There’s some confusion as to who exactly was there in the audience that night, partly because there was another concert just six weeks later, but mostly because it’s considered to be a gig that changed western music culture forever. So iconic and important has that appearance become that David Nolan wrote a book, I Swear I Was There: The Gig That Changed the World, investigating just whose claim to have been present was justified. Because the 4th of June is generally considered to be the genesis of punk rock6.
We know three chords but you can only pick two The Sex Pistols had shown that barely-constrained fury was more important to their contemporaries than art-school structuralism, giving anyone with three chords and something to say permission to start a band. Brewer’s (CAP) Theorem The Significance of the Theorem. Fallacies of Distributed Computing. The Fallacies of Distributed Computing are a set of assumptions that L. Peter Deutsch and others at Sun Microsystems (now Oracle Corporation) originally asserted programmers new to distributed applications invariably make. These assumptions ultimately prove false, resulting either in the failure of the system, a substantial reduction in system scope, or in large, unplanned expenses required to redesign the system to meet its original goals.

Paxos (computer science) Consensus protocols are the basis for the state machine approach to distributed computing, as suggested by Leslie Lamport[2] and surveyed by Fred Schneider.[3] The state machine approach is a technique for converting an algorithm into a fault-tolerant, distributed implementation. Ad-hoc techniques may leave important cases of failures unresolved. The principled approach proposed by Lamport et al. ensures all cases are handled safely.
The Paxos protocol was first published in 1989 and named after a fictional legislative consensus system used on the Paxos island in Greece.[4] It was later published as a journal article in 1998.[5] The Paxos family of protocols includes a spectrum of trade-offs between the number of processors, number of message delays before learning the agreed value, the activity level of individual participants, number of messages sent, and types of failures. The topic predates the protocol. Client Acceptor (Voters) Proposer Learner Leader Non-triviality Safety Liveness(C;L)
