Introduction: It remains that, from the same principles, I now demonstrate the frame of the System of the World. -- Isaac Newton The practice of IT reminds me a lot of the practice of science before Isaac Newton. Aristotelianism was dead, but there was nothing to replace it. Then Newton came along, created a scientific revolution with his System of the World . And everything changed. That was New System of the World number one. New System of the World number two was written about by the incomparable Neal Stephenson in his incredible Baroque Cycle series. It explores the singular creation of a new way of organizing society grounded in new modes of thought in business, religion, politics, and science. Our modern world emerged Enlightened as it could from this roiling cauldron of forces. In IT we may have had a Leonardo da Vinci or even a Galileo, but we’ve never had our Newton. Maybe we don't need a towering genius to make everything clear? For years startups, like the frenetically inventive

Introduction: ZooKeeper is a high available and reliable coordination system. Distributed applications use ZooKeeper to store and mediate updates key configuration information. ZooKeeper can be used for leader election, group membership, and configuration maintenance. In addition ZooKeeper can be used for event notification, locking, and as a priority queue mechanism. It's a sort of central nervous system for distributed systems where the role of the brain is played by the coordination service, axons are the network, processes are the monitored and controlled body parts, and events are the hormones and neurotransmitters used for messaging. Every complex distributed application needs a coordination and orchestration system of some sort, so the ZooKeeper folks at Yahoo decide to build a good one and open source it for everyone to use. The target market for ZooKeeper are multi-host, multi-process C and Java based systems that operate in a data center. ZooKeeper works using distributed processes

Introduction: 3PAR Remote Copy is a uniquely simple and efficient replication technology that allows customers to protect and share any application data affordably. Built upon 3PAR Thin Copy technology, Remote Copy lowers the total cost of storage by addressing the cost and complexity of remote replication. Common Uses of 3PAR Remote Copy: Affordable Disaster Recovery: Mirror data cost-effectively across town or across the world. Centralized Archive: Replicate data from multiple 3PAR InServs located in multiple data centers to a centralized data archive location. Resilient Pod Architecture: Mutually replicate tier 1 or 2 data to tier 3 capacity between two InServs (application pods). Remote Data Access: Replicate data to a remote location for sharing of data with remote users.

Introduction: And by hot I also mean temperature. Summer has arrived. It's sizzling here in Silicon Valley. Thank you air conditioning! Scale the web by appointing a Crawler Czar? Tom Foremski has the idea that Google should open up their index so sites wouldn't have to endure the constant pounding by ravenous crawler bots. Don MacAskill of SmugMug estimates 50% of our web server CPU resources are spent serving crawlers. What a waste. How this would all work with real-time feeds, paid feeds (Twitter, movies, ...), etc. is unknown, but does it make sense for all that money to be spent on extracting the same data over and over again? Tweets of Gold: jamesurquhart : Key to applications is architecture. Key for infrastructure supporting archs is configurability.

Introduction: If you don’t cannibalize yourself, someone else will. -- Steve Jobs America as the New World has a long history of inspiring Utopian communities . Early experiments were famously religious. But there have been many others as new waves of thought have inspired people to organize and try something different. In the 1840s Transcendentalists, believing the true path lay in the perfection of the individual, created intentional communities like Brook Farm . We've also seen socialist , anarchist , hippy , and virtually every other kind of Utopia in-between. Psychologist B.F. Skinner wrote an infamous book, Walden Two , with a more "scientific" take on creating a Utopian community and Ayn Rand in Atlas Shrugged had her free market version. I believe in startup organizations we see the modern version of Utopian energy in action. We now call it by names like "culture hacking", but the goal is the same: to create a new form of human community to achieve a profound go

Introduction: I would like to compile a comparison matrix on the total cost of ownership for .Net, Java, Lamp & Rails. Where should I start? Has anyone seen or know of a recent study on this subject?
Introduction: In Algorithm Design for Performance Aware VM Consolidation we learn some shocking facts (gambling in Casablanca?): Average server utilization in many data centers is low, estimated between 5% and 15%. This is wasteful because an idle server often consumes more than 50% of peak power. Surely that's just for old style datacenters? Nope. In Google data centers, workloads that are consolidated use only 50% of the processor cores. Every other processor core is left unused simply to ensure that performance does not degrade. It's a VM wasteland. The goal is to reduce waste by packing VMs onto machines without hurting performance or wasting resources. The idea is to select VMs that interfere the least with each other and places them together on the same server. It's a NP-Complete problem, but this paper describes a practical method that performs provably close to the optimal. Interestingly they can optimize for performance or power efficiency, so you can use different algorithm
