Not all Muslims speak Arabic." For example, Ismail said, the world's largest Muslim nation is Indonesia, which is not anywhere near the Middle East. "People just don't realize that." It's not just the portrayal of Muslims that is problematic. In several video games, images of the Arab and Muslim world are often inaccurate.

The Google Chrome extension is similar to a spell check function, except instead of flagging misspelled words, it identifies insults and hateful messages and then prompts the user to write something else. That's from the website for Reword, a new Google Chrome extension designed to combat cyberbullying. The tool identifies insulting words in online posts and messages, and then crosses them out with a red line. Developed in Australia by Headspace, which is Australia's National Youth Mental Health Foundation, and ad agency Leo Burnett Melbourne, Reword aims to address online abuse by preventing hateful messages before they're even posted. "Sadly, online bullying is endemic," Headspace CEO Chris Tanti said in a news release.

Changing world: "As the first generation of self-driving cars and battlefield warbots filter into society, scientists are working to develop robots with moral decision-making skills." THE World Science Festival held in Brisbane in early March confirmed that robots, artificial intelligence and machine learning were now part of our lives. Thousands attending the festival came to watch, touch and play with cute, shiny robots capable of dodging objects, following commands and engaging in smart banter. However, if the future has arrived, now we have to deal with it. The World Science Festival was also an important forum as world experts discussed robot morality and ethics and what role we wanted robots to play in the future.

One of the tropes of science fiction is the uncanny valley -- the phenomenon of a robot looking eerily human-like but not quite right in some intangible way. Another is the breakdown in the distinction between human and machine. And a third is artificial intelligence becoming so complex and sophisticated that humans are no longer able to understand or control it. Well, not to be the bearer of bad news, but all of those tropes from the movies are already happening. The good news is that some of these advances have the potential to make our lives a lot better.

Summary: At least one instance of Real Time Predictive Model development in a streaming data problem has been shown to be more accurate than its batch counterpart. Whether this can be generalized is still an open question. It does challenge the assumption that Time-to-Insight can never be real time. A few months back I was making my way through the latest literature on "real time analytics" and "in stream analytics" and my blood pressure was rising. The cause was the developer-driven hyperbole that claimed that the creation of brand new insights using advanced analytics has become "real time".

When Google's AlphaGo program beat grandmaster Lee Se-Dol four games to one, both programmers and professional Go players were surprised. The general consensus was that it would be years before a computer could defeat a human at the complex board game, which players describe as requiring elegance and imagination. Director of the MARCS Institute for Brain, Behaviour and Development and electrical engineering professor, Jon Tapson, said AlphaGo's victory was cause for a re-evaluation of how we use artificial intelligence (AI). "They could find ways of manipulating the stock market -- maybe by buying and selling shares in rapid succession to create the illusion of a change in market sentiment," he said. He said unless there was reason to go looking, it was unlikely humans would notice that kind of behaviour, and that it would be difficult to program or regulate the actions of an AI if we do not know how it makes decisions.

Throughout that history, technology has brought comfort, ease, and prosperity. And all along it has taken jobs, disrupted lives, and changed the way people live and think. Each new age of innovation has brought a revolution. First, there was steam, then mass production, and late last century information technology. Now, researchers and thought leaders have declared a Fourth Revolution: an age of Artificial Intelligence (AI), advanced automation, and sophisticated robotics.

Every day new travel sites and apps are launched that promise to make trip planning easier. Some do and some don't. Here are two free tools optimized for smartphones that I tested and really liked: Lonely Planet's free Guides app for iOS and Android, and Destinations on Google, which makes it easy to aggregate information for your next travel adventure. The app includes more than 35 free importable guides to international and U.S. destinations, from Bangkok to London and Boston to San Francisco. I tested New York, Kyoto and Vancouver.
