HP Announces Support for OpenStack™

(This entry was posted by Emil Sayegh, VP, Cloud Services)


HP is pleased to announce our intent to join and support OpenStack™, an open source cloud infrastructure project.


As the world’s largest technology company, HP is in a unique position to bring together a portfolio that spans printing, personal computing, software, services and IT infrastructure at the point where cloud and connectivity converge. 


HP recognizes that open and interoperable cloud infrastructure and services are critical in delivering the next generation of cloud-based services to developers, businesses and consumers.  It is our belief that close collaboration with developer communities combined with HP’s global portfolio are cornerstones to delivering the right, seamless and secure experiences for our customers.


Over the past year, the OpenStack community has been focused on developing open source software for building private and public clouds.  Today, OpenStack has participation from more than 90 organizations with 1200 participants. 


HP is taking an active role in the OpenStack community and we see this as an opportunity to enable customers, partners and developers with unique infrastructure and development solutions across public, private and hybrid cloud environments.  In fact look for members of our cloud development teams that are already actively participating on OpenStack’s Launchpad and irc channel (#openstack on 


We are also sponsoring the OpenStack Design Summit and OpenStack Conference in October ’11, where we look forward to sharing and engaging with you further to bring about the future of open, interoperable cloud services. See you in Boston!


Please follow us on Twitter: @hpcloud and continue to check back here in the coming weeks and months for updates on our work with OpenStack.

HP Personalized Video App Allows You to Control Your Online Video Experience

(This entry was posted by Rony Thomas, HP India Corporate Communications)



With over 35 hours of video uploaded every minute on YouTube, the Internet has democratized video by giving users the power to easily create, package and distribute content. In fact, YouTube claims that more video is uploaded on their portal in a month than what the three major US cable networks have created in 60 years.  But how does a user more easily find relevant videos that he or she will enjoy, and how can the user better control this experience?


Our researchers at HP Labs in India have addressed these challenges by creating a personalized video application that uniquely combines personal recommendations and a TV-like “lean-back” experience for online video consumption. The recently launched beta application allows users to create channels using keywords that match a given preference.  The app will then pull in videos that match these keywords.


As with a TV, you can select a channel and videos will play one after the other without intervention, delivering a more personalized video viewing experience.  The application also integrates web pages related to the video being watched and allows for social sharing through Twitter and Facebook. 


The application is part of a larger vision to create simplified experiences and rich user interfaces for HP’s next one billion customers. In emerging markets such as India, the video web is expected to play a dominant role in the Internet experience due to its ability to transcend linguistic barriers associated with text-based content.

HP Labs study gives new insight into user behavior on Chinese social network Sina Weibo

Social media has exploded in popularity in China – HP’s launch of a Chinese-language blog two weeks ago is just one indication.  Still, scientists and sociologists around the world are only beginning to turn their attention towards understanding how these services are actually being used.


Adding to this nascent body of research, a paper published today by HP Labs delivers new insights into the content-sharing preferences of users on Chinese microblogging service Sina Weibo.


The paper, titled “What Trends in Chinese Social Media,” [PDF] highlights HP’s unique approach to data analysis and follows a series of recent announcements about the company’s investments in the areas of cloud computing, R&D and social media in China.



Why study social media in China?


As the country with the largest number of Internet-connected citizens (420 million as of June 2010 [pdf]), the rise of social media in China has been particularly explosive.


For example, Sina Weibo -- a Chinese microblogging site similar to Twitter -- has already amassed over 140 million users as of May 2011, nearly all of whom are located inside China and post in the Chinese language.


One of the principal tasks of the Social Computing research group at HP Labs is to create software analytics and algorithms that can add meaningful context to the huge data sets produced by those millions of social media users.


For example, in 2010 the Social Computing team introduced an algorithm that ranks Twitter users according to their influence.  This algorithm has a number of applications, from spam filtering or advertising targeting to recommending what users to follow.


 Key takeaways from the research


For their experiment, HP scientists examined the topics that are most popular on Sina Weibo during a 30-day period and compared them to previous findings from research on Twitter. According to the paper’s authors, Louis Yu, Sitaram Asur, and Bernardo Huberman, there are significant differences in the content shared in China, when compared to a global social network such as Twitter:


- In China, people tend to use Sina Weibo to share entertainment-type content such as jokes, images, and videos, and a significantly large percentage of posts are “retweets” (a re-posting of another user’s tweet).  The trends that are formed are almost entirely caused by retweets of this kind of content.


- In contrast, prior HP research shows that trending topics on Twitter have more to do with current events than entertainment and that the effect of retweets is not as large (although it is still substantial).


- There are more unverified accounts among the top 100 trend-setters on Sina Weibo than on Twitter, and most of the unverified accounts feature discussion forums for user-contributed videos, images, and humor.


“It is important to note that the differences in behavior between the two user bases are relative and not absolute,” says Bernardo Huberman, director of HP’s Social Computing lab.  “The study doesn’t suggest that news-sharing does not occur on Sina Weibo, because it certainly does.  However, our experiment does show that this type of behavior was relatively less common than on Twitter during the trial period.”


The paper also includes a brief history of social media in China and illustrates key differences in how Sina Weibo and Twitter work.


Future plans for researching Chinese social media


The HP Labs researchers responsible for this research are already planning to build on this initial work, as demand for social media analytics in China is sure to continue to grow.


“This paper is just the beginning,” adds Huberman.  “It is useful and interesting for us to understand at an aggregate level the type of content being shared on  services like Sina Weibo, but we believe there is even more value for HP and our customers in understanding the flow of content among specific, influential individuals on the network.”

Frequently asked questions about the research


Why are posts on Sina Weibo referred to as “tweets”?


On Sina Weibo, the act of “retweeting” is called “zhuanfa,” which actually means “retweet” in Chinese.  Rather than defining “zhuanfa” in the paper, the authors chose to use this translation.


What is a “trending topic”?


Trending topics reveal popular themes from current discussions on a social network.  Sina Weibo offers a list of 50 keywords that appear most frequently in users’ tweets over the past hour.  They are ranked according to the frequency of appearances.  Similarly, Twitter provides users a list of the top ten trending topics of the moment.


What is a “verified account”?


Both Twitter and Sina Weibo authenticate certain accounts, verifying the ownership and identity of the account holder.  This authenticity is communicated to other users via a badge or other visual cue.

Striving for Net-Positive Environmental Impacts

A diverse group came together again at the 2011 Aspen Ideas Festival to discuss big ideas, which included HP’s Chandrakant Patel, an HP Fellow and Director of the Sustainable Ecosystems Research Group of HP Labs. Patel presented on the sustainable city of tomorrow and cleantech innovations for the transportation sector, topics he explores in a video interview with Thomson Reuters:



 Part of the HP sustainability strategy that he discusses includes a focus on fundamentals, such as taking into account both energy supply and demand when designing systems, as well as factoring in energy use across the entire product lifecycle (i.e., mining, manufacturing, use and recycling).


Another key concept is tapping into the connectivity that millions of mobile and handheld devices offer new services, for instance, to streamline public transportation – without rebuilding our infrastructure. The interview also explores the micro-grid concept, including localized data center cooling and power grids fueled by wind, solar and bio-gas and the concept of a net-zero data center.
