Is Microsoft engaging in digital imperialism?

Windows, the common carrier of Microsoft, is such a sordid mess that it suffers regular glitches and conducts mass surveillance on users. Microsoft knows that without Windows it cannot survive, so dirty tricks resume in a very big way. This is not a beep on the radar but somewhat of a surge.

Numerous anonymous blogs were created to attack Munich over this and provocateurs of Microsoft loved citing them, only to be repeatedly proven wrong. Microsoft is trying to make an example out of Munich in all sorts of nefarious ways. We need to defend Munich from this malicious assault by the convicted monopolist and corrupt enterprise that’s acting as though it fights for its very survival (while indeed laying off tens of thousands of employees).

GSoC: Thumping the Malaria and voyaging in cosmos with KStars

Let's talk about my project now. KStars is desktop planetarium application under KDE Education Projects. I developed QML based cool interface to enable users to browse through image database of community of astrophotographers (i.e. astrobin.com) which contains more than 1,20,000 (number is increasing everyday) real time and very high resolution images along with various information related to them (i.e. Date on which image was captured, Bortle Dark-Sky Scale, RA Centre, DEC Centre, Telescope or Camera used, Description added by astrophotographer etc).
