Gooogle is still the only company whose name is synonymous with the verb search

The story of Google's algorithm begins with PageRank, the system invented in 1997 by cofounder Larry Page while he was a grad student at Stanford. Page's now legendary insight was to rate pages based on the number and importance of links that pointed to them - to use the collective intelligence of the Web itself to determine which sites were most relevant. It was a simple and powerful concept, and - as Google quickly became the most successful search engine on the Web - Page and cofounder Sergey Brin credited PageRank as their company's fundamental innovation.

But that wasn't the whole story. "People hold on to PageRank because it's recognizable," Manber says. "But there were many other things that improved the relevancy." These involve the exploitation of certain signals, contextual clues that help the search engine rank the millions of possible results to any query, ensuring that the most useful ones float to the top.

Web search is a multipart process. First, Google crawls the Web to collect the contents of every accessible site. This data is broken down into an index (organized by word, just like the index of a textbook), a way of finding any page based on its content. Every time a user types a query, the index is combed for relevant pages, returning a list that commonly numbers in the hundreds of thousands, or millions. The trickiest part, though, is the ranking process - determining which of those pages belong at the top of the list.

In an age of open source, custom-fabricated, DIY product design, all you need to conquer the world is a brilliant idea.

The door of a dry-cleaner-size storefront in an industrial park in Wareham, Massachusetts, an hour south of Boston, might not look like a portal to the future of American manufacturing, but it is. This is the headquarters of Local Motors, the first open source car company to reach production. Step inside and the office reveals itself as a mind-blowing example of the power of micro-factories.

In June, Local Motors will officially release the Rally Fighter, a $50,000 off-road (but street-legal) racer. The design was crowdsourced, as was the selection of mostly off-the-shelf components, and the final assembly will be done by the customers themselves in local assembly centers as part of a “build experience.” Several more designs are in the pipeline, and the company says it can take a new vehicle from sketch to market in 18 months, about the time it takes Detroit to change the specs on some door trim. Each design is released under a share-friendly Creative Commons license, and customers are encouraged to enhance the designs and produce their own components that they can sell to their peers.
