I build for me….

I build tools for my use. Hardware, Software, and services. I build not to sell, rent and/or give to others. One cannot solve the problems of others, until she can solve her own.

While I am supporter of Free Software, both beer and freedom, I most importantly support the freedom to do what you want. This is because I don’t want anyone telling me what to do with my life.

If I follow your instructions, know that it is because I deem it in my own best interest. Our goals have been aligned. Nothing more, nothing less.

Automata

Leave a reply

Automata theory is the study of abstract machines and automata, as well as the computational problems that can be solved using them. It is a theory in theoretical computer science and discrete mathematics (a subject of study in both mathematics and computer science). The word automata (the plural of automaton) comes from the Greek word αὐτόματα, which means “self-acting”.
