Managing to-do lists using mind mapping software


For more than ten years now I have been using a mind mapping software to manage my to-do lists and all the tasks I want to do during the next week. Before that I was struggling to keep track of all the things I wanted to do using text editors, post-its or even my (yikes!) unreliable memory.

Development of a hobby programming project

How ImagingInterface got started


I started many hobby programming projects in my life, and most were never completed. I recently started working on a new project which I hope I’ll bring to a more “finished” state than all the others I worked on. This project involves a lot of work, but the good thing is that it can become…
