...I started thinking about all the services I’ve used for taking notes and thought it would be a good idea to share them with you and while I’m at it, to make a list of any others that I find. Now, when it comes to note taking, I personally look for quick and simple. If I have something on my mind, I don’t want to go through some advanced system and climb a mountain just to save a note for myself. There won’t be all the note taking tools out there on my list, but ones that I feel get the job done well...

The goal of the study on Fun and Software Development (FASD) is to precisely assess the importance that fun has as motivation for software developers to engage in open source projects. A survey carried out both under open source developers and programmers working in Swiss software companies yielded that the fun motive accounts for about 27 percent to 33 percent of open source developers’ motivation.
Fun is a pervasive feature of software development, not only for open source programmers but in the area of commercial software development too: Open source developers that are paid for their work are observed to be very motivated and prepared for future effort, especially if they enjoy their development time. Furthermore, the fun that programmers experience functions as a good proxy for their productivity. Therefore, employers that want to enhance the programmers’ productivity can safely invest in an environment of fun for developers in their company.

What is GeoGebra? 
GeoGebra is a dynamic mathematics software for education in secondary schools that joins geometry, algebra and calculus.
On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.

On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.

These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa."
