From the The Physics arXiv Blog: “The way we view online recipes reveals how our eating habits change over time, say computational sociologists….it’s no surprise that computational sociologists have begun to mine the data associated with our browsing habits to discover more about our diets and eating habits. Last year we looked at some fascinating work examining networks of ingredients and the flavours they contain, gathered from online recipe websites. It turns out this approach gives fascinating insights into the way recipes vary geographically and into the possibility of unexplored combinations of flavours.
Today, Robert West at Stanford University and Ryen White and Eric Horvitz from Microsoft Research in Redmond, take a deeper look at the electronic trails we leave when we hunt for food on the web. They say the data reveals important trends in the way our diets change with the season, with our geographical location and with certain special days such as Thanksgiving and Christmas. And they conclude that the data could become an important tool for monitoring public health.”

Quarter of time online is spent on social networking
Experian: “Insights from Experian, the global information services company, reveals that if the time spent on the Internet was distilled into an hour then a quarter of it would be spent on social networking and forums across UK, US and Australia. In the UK 13 minutes out of every hour online is spent on social networking and forums, nine minutes on entertainment sites and six minutes shopping.”
Africa’s digital divide: still gaping
Peter Vanham in the FT’s Beyond Brics blog: “Don’t let success stories like M-Pesa in Kenya fool you: the worldwide digital divide is still increasing and Africa remains the biggest victim.” So says Soumitra Dutta, Dean of Cornells’ Johnson School of Management, talking to beyondbrics at the launch of the World Economic Forum’s Global Information Technology Report 2013.
M-Pesa, the highly successful mobile payments service in Kenya, has attracted global attention. Used by the vast majority of Kenyans, M-Pesa is so successful that, according to Quartz, a massive 31 per cent of Kenya’s GDP is spent through mobile phones.
It was proof that technological progress could happen in low-income countries with poor infrastructure. It has been copied in other emerging markets, leading some to believe the so-called digital divide between the developed and the developing world was ready to fall.
But the opposite is true, says the Indian born Dutta, a founding author of the WEF’s IT report….
To support his claim, Dutta refers to the latest available data on access to different mobile technologies (see graph – click to enlarge).”:
New OECD paper on Machine-to-Machine Communications
Machine-to-Machine Communications – Connecting Billions of Devices: “This document examines the future of machine-to-machine communication (M2M), with a particular focus on mobile wireless networks. M2M devices are defined, in this paper, as those that are actively communicating using wired and wireless networks, are not computers in the traditional sense and are using the Internet in some form or another. While, at the global level, there are currently around five billion devices connected to mobile networks, this may by some estimates increase to 50 billion by the end of the decade. The report provides examples of some of the uses to which M2M is being put today and its potential to enhance economic and social development. It concludes that to achieve these benefits, however, changes to telecommunication policy and regulatory frameworks may be required. Some of the main areas that will need to be evaluated, and implications of M2M assessed, include: opening access to mobile wholesale markets for firms not providing public telecommunication services; numbering policy; frequency policy; privacy and security; and access to public sector information.”
Map of the internet could make it stronger
From the Scientist: “In many ways the internet is like another country. It has its own communities, cultures and even currency. But its infrastructure – the fibre optic cables that span the globe, and the thousands of buildings housing servers and routers – passes through almost every nation…. Previous attempts to map the internet have been from within, using “sniffer” software to report the IP addresses of devices visited along a particular route, which, in theory, can then be translated into geographical locations. But this approach doesn’t work,… Barford and Roughan head up two separate projects that are attempting to change that. Instead of relying on sniffers, they are scouring ISP databases to find published information about local networks, and piecing these together into a global map. Roughan’s Internet Topology Zoo is a growing collection of maps of individual networks. Barford’s Internet Atlas expands on this, adding crucial buildings and links between networks to flesh out the map. So far the Internet Atlas, perhaps the most comprehensive map of the physical internet, maps 10,000 such structures and 13,000 connections.”
