Dryad: A general-purpose distributed execution platform
Google Tech Talks
November, 1 2007
ABSTRACT
Web search has generated the need and economic support for a new class of data-intensive supercomputing applications. Several computing platforms have been created to support this need: the first described in the literature is Google's MapReduce. I will describe the architecture of the Dryad system developed at Microsoft Research, and explain some of our design choices. Dryad allows more general computations than MapReduce, and has consequently been used as a middleware abstraction on which higher-level programming models can be implemented. I will also briefly discuss some of these.
Speaker: Michael Isard
Michael Isard started out as a computer vision researcher, but has gradually been lured into systems research by his colleagues, first at DEC/Compaq SRC and now at Microsoft Research Silicon Valley. He was closely involved in the design and implementation of the first version of Microsoft's in-house search engine, and his systems research subsequently has concentrated on programming models for parallel and distributed computing.

Using YouTube with a Purpose - Helping Kids in Bangladesh
"This is probably the coolest thing that has ever happened to me." - Hank Green
If it wasn't for YouTube, I couldn't have done this.
It's thanks to YouTube that I was able to team up with Rick Davis - an American school teacher in Bangladesh who got in contact with me after finding one of my videos on YouTube. He helped pay and plan this trip this rural village in a military-controlled and malaria heavy part of Bangladesh. And, of course, I couldn't have done this without the support of John and Hank Green and all the Nerdfigthers out there.
Hank Green's donation went to Rithanu - an 11 year old malaria survivor. Hank's YouTube channel is:

Patrick's donation went to help 7 year old Jack (who, if I heard correctly from the locals, is also a malaria survivor). Patrick's YouTube channel is:

The donation of a PermaNet (a long lasting insecticide treated mosquito net) was made possible with the help of Vestergaard-Frandsen. Vestergaard-Frandsen manufactures PermaNets along with other products that help control the spread of disease in the developing world. You can find more information at:

I was neither paid nor required to endorse their products. I endorse them because their products work - I've witnessed this first hand. If you'd like to donate one of their products, check out my recommended charities list:

Full Disclosure Regarding Rick Davis: Rick Davis (the teacher at the American International School in Dhaka) is associated with this NGO and helped design the sponsorship program. His involvement with this NGO is voluntary and unpaid. He was not paid nor financially benefits from endorsing this NGO's sponsorship program.

Common Purpose the Unseen Invasion - Brian Gerrish
Brian Gerrish discovered the hidden machinations of Common Purpose in Plymouth England some time ago. CP influence is seen in force throughout the BBC, Local Councils, Police, Schools, National Health Service, and many government agencies that run towns in the UK. Leading toward ever closer union, it is a subversive way to set up new leaders of the coming Totalitarian Socialist State (The European Union). Bringing people in through 'Self Improvement' courses, the talented are picked and indoctrinated in CP ideology. Destined to break up traditional viewpoints it is a very effective and hidden tool of manipulators behind the scenes. Many CP trained 'leaders' are well aware of the true purpose of the organization, most are not but are serving the goal as a result of their retraining in the CP mode of thinking. Brainwashing, a cult, a subversive organization, are terms redily applied to the methods and organization of the group. (check out my other videos on Google Video, Yahoo Video) (Disclaimer: Views and opinions presented here are for informational and educational purposes only and may not necessarily be those of the makers of this video.)

General Purpose, Low Power Supercomputing Using...
Google TechTalks
February 28, 2006
Prof. Bob Brodersen
ABSTRACT: The ability of FPGA technology to exploit the advances in IC fabrication technology has resulted in the present situation in which a FPGA computing fabric is the most power and area efficient approach for general purpose parallel computing. This has occurred because the Von-Neumann processor architectures are now power limited and can no longer fully exploit the technology advances (thus the move to multi-cores). Hardware composed of arrays of FPGA's and memory has been design that achieves a TeraOp/second of performance per board with over an order of magnitude higher efficiency for the computation per unit power over conventional...
