*Almost ALL software was written by me ALONE from scratch and without any toolboxes etc. of other authors with very few exceptions (see co-authors about what they did)

**Of course, this is an approximate value : I calculated it by dividing the size of source files in bytes by an average length of a line of code (30). Also, I tried not to take into account code already counted in other projects

***Actually, utilities are the most common type of software for large projects and many are simply NOT MENTIONED here. Large projects usually require not only much programming, but also preparation of huge amounts of data. For example, for a navigational simulator we need to construct a binary representation of a visual scene, or tesselate sea region into triangles to learn if a ship is inside sea or not etc.
