I got a ( TSSP: Theoretical Solid State Physics ) PhD ( [login to view URL] ) at UCSD in 1983. Later on I was involved in simulation of Complex Systems: I introduced an order parameter for the TSP ( Traveling Salesman Problem ) and TSSP. As a byproduct I became involved in the support of web site at Caracas for around 4 years. I am heavily involved with tools as HTML, HTML5, CSS, CSS3, JavaScript, PHP, LaTeX, C and C++. Several years ago, I was using Java but I left it when JavaScript started with <canvas>. I started to use JavaScript from the very begining ( around 20 years ago ).
