The internet has plenty of advantages, but also (at least) two disadvantages for the digital human being: the constant availability of slightly interesting information and the constant possibility of getting a quick shot of self esteem through social media likes. Related to that, but fortunately only a temporary issue, is …
Update January 2017
The European commission came to similar conclusions as those below - and limited the effects of its end-of-roaming-initiative to disallow a real competition between carriers from different European countries. Unfortunately, we will still suffer from limited competitions and widely varying offerings within the single market.

Facebook and, to a lesser degree, twitter, are commonly referred to as social networks, i.e., as tools to organize friends, family and followers and communicate with them via messages, wall posts, status updates and tweets. But they also serve as a tool to keep …
Exercise 1
% there are several ways for creating these arrays
% 1 - squared brackets
A = [1 3 5; 3 6 3; 9 8 5]
% 2 - functions for array creation
A = rand(3)
A = magic(3)
b = [3; 4: 8] % 3 x 1 - column vector!
A * b(1)
A …Previous articles explored julia and its plotting facilities in the Winston package. The workflow used there, (i) data import, (ii) plotting and (iii) graphics export, will be used in this article as well, however, this time using Dataframes and Gadfly in julia and dataset arrays in MATLAB.
Dataset arrays are …
In the last posts I installed julia, some graphics packages and some dependencies on a Mac and compared one way of plotting in julia - using Winston and plotting several datasets into one plot - with the typical approach in MATLAB. This post will show how to plot each individual dataset into …
A number of excellent free open-source alternatives to MATLAB have arrived in the last couple of years that have managed to bite away parts of MATLAB's market share. Most notable are R, which is now the dominant language for statistical computing and bioinformatics and Python (with numpy, scipy etc.) which …
Julia is a relatively novel language intended for technical computing, basically a direct contender of MATLAB/Octave, Python/scipy/numpy or R. The crucial difference between Julia and the other languages is its powerful JIT compiler, which is responsible for some impressive benchmark results. I'm exploring Julia as a replacement …
