Detect recursion using state variables
As you might know Perl version 5.10 has introduce a keyword called state that allows the creation of so-called state variables. These are very similar to the static variables of C. You declare them insied a function. They are scoped to the function so you cannot reach them from the outside, but they never get destroyed and they are initialized only once.
Dave Horsfall suggested to use this feature to detect unwanted recursion. Or calling the same function twice.
Course Management Application in Mojolicious
In my training course I give exercises to my students. They can (and in some of these course they must) submit them. I can then review them and give comments. I would like to have a web application to keep track of all the exercises and the submission.
In this experimental project Mark Gardner and myself will develop this application using live pair programming.
Course Management Application in Mojolicious - part 2
The second part of the live development course management application using Mojolicous together with Mark Gardner.
