Introducing Google Cloud Datastore -

nosql:

Urs Hölzle in a post summarizing some of the announcements at Google I/O:

Google Cloud Datastore is a fully managed and schemaless solution for storing non-relational data. Based on the popular App Engine High Replication Datastore, Cloud Datastore is a standalone service that features automatic scalability and high availability while still providing powerful capabilities such as ACID transactions, SQL-like queries, indexes and more.

I’m heading over to the project’s site to read more.

What Open Source Hadoop Coming to Windows Means to IT -

nosql:

This will open up Hadoop to a large number of organizations that have no in- house Linux skills. Shaun Connolly, vice president of Corporate Strategy at Hortonworks, explains the thinking behind moving HDP to Windows in this way: “Essentially it’s a market-driven decision,” he says. “Hadoop is built for the scaleout commodity hardware market, and the commodity hardware market is 70% Windows by install base and expertise.”

Employees in Windows-only companies will be able to make use of Hadoop easily because Excel can be used as a business intelligence tool to view the results of Hadoop Big Data analysis (whether Hadoop is running on Windows or Linux). “Ideally we want Microsoft users to be oblivious to the fact that everything is coming from Hadoop,” says Connolly. “If end users can consume data without any learning curve, thanks to tools like Excel, then they get more value.”

Either the data or the logic above is not sound:

  1. those Windows machines that make up the 70% of the market are probably running Excel
  2. those 70% of the market Windows machines are not going to run Hadoop

Based on this sort of market-share decisions, tomorrow we should see Hadoop for iOS and Android and Nokia. Sometime soon Microsoft will release Excel for iOS and maybe Android.

The Man Behind the Google Brain: Andrew Ng and the Quest for the New AI  There’s a theory that human intelligence stems from a single algorithm. The idea arises from experiments suggesting that the portion of your brain dedicated to processing sound from your ears could also handle sight for your eyes. This is possible only while your brain is in the earliest stages of development, but it implies that the brain is — at its core — a general-purpose machine that can be tuned to specific tasks. About seven years ago, Stanford computer science professor Andrew Ng stumbled across this theory, and it changed the course of his career, reigniting a passion for artificial intelligence, or AI. “For the first time in my life,” Ng says, “it made me feel like it might be possible to make some progress on a small part of the AI dream within our lifetime.” In the early days of artificial intelligence, Ng says, the prevailing opinion was that human intelligence derived from thousands of simple agents working in concert, what MIT’s Marvin Minsky called “The Society of Mind.” To achieve AI, engineers believed, they would have to build and combine thousands of individual computing modules. One agent, or algorithm, would mimic language. Another would handle speech. And so on. It seemed an insurmountable feat. When he was a kid, Andrew Ng dreamed of building machines that could think like people, but when he got to college and came face-to-face with the AI research of the day, he gave up. Later, as a professor, he would actively discourage his students from pursuing the same dream. But then he ran into the “one algorithm” hypothesis, popularized by Jeff Hawkins, an AI entrepreneur who’d dabbled in neuroscience research. And the dream returned. It was a shift that would change much more than Ng’s career. Ng now leads a new field of computer science research known as Deep Learning, which seeks to build machines that can process data in much the same way the brain does, and this movement has extended well beyond academia, into big-name corporations like Google and Apple. In tandem with other researchers at Google, Ng is building one of the most ambitious artificial-intelligence systems to date, the so-called Google Brain. This movement seeks to meld computer science with neuroscience — something that never quite happened in the world of artificial intelligence. “I’ve seen a surprisingly large gulf between the engineers and the scientists,” Ng says. Engineers wanted to build AI systems that just worked, he says, but scientists were still struggling to understand the intricacies of the brain. For a long time, neuroscience just didn’t have the information needed to help improve the intelligent machines engineers wanted to build. What’s more, scientists often felt they “owned” the brain, so there was little collaboration with researchers in other fields, says Bruno Olshausen, a computational neuroscientist and the director of the Redwood Center for Theoretical Neuroscience at the University of California, Berkeley. The end result is that engineers started building AI systems that didn’t necessarily mimic the way the brain operated. They focused on building pseudo-smart systems that turned out to be more like a Roomba vacuum cleaner than Rosie the robot maid from the Jetsons. But, now, thanks to Ng and others, this is starting to change. “There is a sense from many places that whoever figures out how the brain computes will come up with the next generation of computers,” says Dr. Thomas Insel, the director of the National Institute of Mental Health.

WhatsApp is bigger than Twitter -

courtenaybird:

According to WhatsApp CEO Jan Koum, the service now has more than 200-million users, making it a larger overall network than Twitter. Moreover, it is being employed heavily by those users, with 8 billion inbound and 12 billion outbound messages every day and no reported drop off since its decision to charge $0.99 a year. With competition growing from Chinese rival WeChat and its 300 million users, of whom 40 million live outside of China, it will be interesting to see how WhatsApp’s growth continues going forward.
