Milestones

IL motore di ricerca, quello con la G, ha raggiunto quota un trilione (1,000,000,000,000) di pagine indicizzate, e commenta con giusto un filino di spocchia, peraltro giustificatissima, la grandezza dei dati:

Today, Google downloads the web continuously, collecting updated page information and re-processing the entire web-link graph several times per day. This graph of one trillion URLs is similar to a map made up of one trillion intersections. So multiple times every day, we do the computational equivalent of fully exploring every intersection of every road in the United States. Except it'd be a map about 50,000 times as big as the U.S., with 50,000 times as many roads and intersections.

As you can see, our distributed infrastructure allows applications to efficiently traverse a link graph with many trillions of connections, or quickly sort petabytes of data, just to prepare to answer the most important question: your next Google search.

 Auguri per il traguardo, anche se il gogool di pagine indicizzate è ancora lontano :)
