At one time, in the 90’s, I had mastered 25 different programming/coding languages, but soon recognized I had to become focused, so even before I moved 100% to the Linuxs OS in 2007, I began to focus on PHP as I saw it becoming the pre-dominant internet language and when the IISC, annouced the legal vs. illegal languages, in 2012, I knew I had made the right choice.
So now I am focused on just PHP, BASH and PHP written frameworks, speicializing on extending capabilities for those frameworks.
