GitHub contributions graph

After reading Mark Story‘s “Coding every day” post, I started checking my own GitHub contributions chart once in a while.  Until today, I haven’t noticed that the chart has two different modes.  One is your public contributions, seen by people who are not part of your organization’s and private projects.  Here is how mine looks. (Notice the “Public contributions” title of the graph).

Yeah, I know, pathetic.  And here is how the full contributions chart looks like, for me and people who have access to see my private projects activities.  The graph is for the same period. (Notice a simpler “Contributions” title of the graph”).

Could be better, but not as bad anymore.  Now with that I’ll try to push more stuff to the Open Source side of things again.

Android now has 1 billion active users

Google is releasing some stats at their Google I/O event.  According to The Next Web, they’ve now switched from device activation counters to 30-day user activity metric.  Here’s how the growth over the last few years looks like:

That’s a lot in my book.  With about 7 billion people living in the world, that’s 1 in every 7 people on the planet uses an Android device.

Corruption in Cyprus

Around 55 per cent of companies in Cyprus who took part in a public tender over the last three years claim that corruption prevented them from winning the contract, the highest percentage in the EU, according to the Commission’s anti-corruption report published on Monday.

Conflicts of interest in bid evaluation were reported in 76 per cent of cases, collusive bidding in 68 per cent, abuse of negotiated procedures in 62 per cent, unclear selection or evaluation criteria in 61 per cent, and amendment of contract terms after the contract is concluded stood at 55 per cent.

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 table for querying the probable implications of data

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.
