Until now, it was particularly difficult to obtain reliable figures on the results of the Android operating system in China. Indeed, there is no “centralized app store” and most smartphones sold in the country do not use Google services, including activation. In fact, it is very difficult to know the actual results. The search engine Baidu has corrected this by publishing a report on trends in the mobile internet for the 3rd quarter 2013. It appears that there would be now 270 million active users of the Google platform in the country (more than 20% of the total population). Growth would, however, decrease with a small 13% against 55% for the same period last year but up 10% compared to Q2 2013.

BayesDB, a Bayesian database, lets users query the probable implications of their data as easily as a SQL database lets them query the data itself. Using the built-in Bayesian Query Language (BQL), users with no statistics training can solve basic data science problems, such as detecting predictive relationships between variables, inferring missing values, simulating probable observations, and identifying statistically similar database entries.
BayesDB is suitable for analyzing complex, heterogeneous data tables with up to tens of thousands of rows and hundreds of variables. No preprocessing or parameter adjustment is required, though experts can override BayesDB’s default assumptions when appropriate.
BayesDB’s inferences are based in part on CrossCat, a new, nonparametric Bayesian machine learning method, that automatically estimates the full joint distribution behind arbitrary data tables.

Reportr is a complete application which works like a dashboard for tracking events in your life (using a very simple API). With a simple interface, it helps you track and display your online activity (with trackers for Facebook, Twitter, GitHub, …) or your real-life activity (with hardware trackers or applications like Runkeeper).
The project is entirely open source and you can host your own Reportr instance on your own server or Heroku.
