Last year, Google announced Caffeine project to improve on web page indexing, accuracy and comprehensiveness of results and now, Caffeine is ready to be rolled out.
Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.
With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.
Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles. – official blog
As web content goes real time, Google needs to keep indexing them as and when the fresh content arrives – Caffeine does exactly that.
Twitter has an official URL shortening service, t.co
Twitter, in a blog post has announced the launch of an official URL shortening service, t.co to wrap the URLs present in tweets. Not necessarily a bit.ly (and other shortening service) killer, the service is aimed at displaying links in a way that removes the obscurity of shortened link and lets you know where a link will take you.
For instance, a NextBigWhat.com post could be displayed as http://www.NextBigWhat.com/cell-id-location-based-service-platform-for-indian-mobile-developers-loc8-297/ or NextBigWhat.com/celli-d.. or simply shorten it using the official shortener (though, we have implemented our own shortener – e.g.. http://NextBigWhat.com/?p=7852 ). The meta data will be used to collect metrics for each and every tweet (that contains URL).
In addition to a better user experience and increased safety, routing links through this service will eventually contribute to the metrics behind our Promoted Tweets platform and provide an important quality signal for our Resonance algorithm—the way we determine if a Tweet is relevant and interesting to users. We are also looking to provide services that make use of this data, an example would be analytics within our eventual commercial accounts service. – blog

- Twitpic has launched Face Tagging.
- Apple has launched Safari 5, which has plugins/extensions as well. No doubt that Safari 5 renders Pluggd.in faster than Chrome (and is much better experience than Opera)
