The names of kings are scraped off coins in days, But Ahmad's name no coiner can erase! The name contains the whole phropetic line, the way that ten includes one through to nine. Rumi <Masnavi>. Is it Persian ref to binary base 2 number system or a subtlety lost in translation?

@linuxtoday @java Java contributes to popularisation of Object Orientated programming giving paradigms like polymorphish to express complex problems elegantly, whilst enforcing safety with type system & memory management, but even with modern IDE is it now too verbose?

@IngridEliseV Learn a new language, write it fluently, know it inside out, extend and add to it, develop tools, create a new language, write theoretical papers formalising concepts to enable new tech ecosystems... different perspectives on software dev
