Google may be taking the ill-conceived Nexus Q back to the drawing board, but the Nexus 7 tablet has been quite a hit since it went on sale a few weeks ago. Since then, though, Google has faced a number of supply issues and the company even suspended sales of the 16GB for a few days to catch up with demand. The latest data from ad network Chitika shows how those supply issues have stalled the growth of Google’s first tablet – at least when measured by web traffic from Nexus 7 owners. Just a few weeks ago, Chitika reported that the Nexus tablet was on its way to surpass the Kindle Fire in its traffic rankings. By now, the company predicted, the Google tablet was supposed to be ahead of the Fire. Instead, its latest data shows that it’s still trailing Amazon’s tablet by quite a bit.

A newly discovered water source could supply half of Africa's driest sub-Saharan country with 400 years of water, reports Matt McGrath of BBC . The new aquifer – called Ohangwena II – flows under the border between Angola and Namibia, covering an area of about 43 miles by 25 miles on Namibia's side. The water is up to 10,000 years old and cleaner to drink than many modern sources.  Project manager Martin Quinger told BBC that the stored water could last 400 years based on the area's current supply. Currently the 800,000 people living in the northern part of the country get their drinking water from a 40-year-old canal that brings the scarce resource from Angola. Quinger added that Ohangwena II could change the nature of farming in the area, which has only been viable near two rivers in the region, and could act as a natural buffer for up to 15 years of drought.
