Nice overview how to avoid NullPointerExceptions in your Java code. I learned about: Nullable, NotNull annotations and the existence of a NullObject Pattern.
A NullPointerException in Java application is best way to solve it and that is also key to write robust programs which can work smoothly. As it said “prevention is better than cure”, same is true with nasty NullPointerException. Thankfully by applying some defensive coding techniques and ...

TOTALLY BADASS!
I have just discovered a whole new dimension to classical sculpture. If you dress the sculptures as hipsters it gives them an awesome new look. They become contemporary and totally badass. Needless...

Microsoft protests against data protection:

This and much more can be found on the platforms https://lobbycloud.eu/ and http://lobbyplag.eu/ which make the influence of lobbies in politics more transparent! 

This is REALLY GREAT!

I have written a text as a pupil about (infinite) collections of circles rolling ontop of each other.  I needed 10 years and a phd in mathematics before somebody points out this intimate relation to FourierAnalysis!! Thank you +Iman Matani !
 
The smooth motion of rotating circles can be used to build up any repeating curve even one as angular as a digital square wave. Each circle spins at a multiple of a fundamental frequency, and a method called Fourier analysis shows how to pick the radiuses of the circles to make the picture work. Decomposing signals like this lies at the heart of a lot of signal processing .

Der NSA-Abhörskandal zieht immer weitere Kreise -- doch der Mann, der durch seinen Mut die Lauschangriffe aufgedeckt hat, steckt nach wie vor in Russland fest. Kanzlerin Merkel, deren Handy jahrelang angezapft wurde, hat nun endlich reagiert. Sie könnte ein wichtiges Zeichen setzen: Asyl für Snowden in Deutschland. Endlich kommt Bewegung in den Fall Snowden -- angesichts der jüngsten Enthüllungen wird bereits von mehreren deutschen Politikern ge...

Yes, the sides follow a tan-graph. See https://en.wikipedia.org/wiki/File:Unitcircledefs.svg
