COBOL: Completely Obsolete But Omnipresent Language

The programming language COBOL is a nuisance, something everyone wants to get rid of; however, I’m about to advise you to learn it. It might be a gold mine. The IT world is a fast paced one where obsolescence is the rule and where things evolve so fast that any person who wants to understand it has to continuously learn and train. Languages, methodologies and technologies keep on changing, evolving to make programming easier, safer more robust and above all, faster. As to every rule, there is one exception. In 1959, convinced that the English language would be more suitable for programming than machine code or the assembly language, Grace Hopper creates the first ever human-readable programming language that would survive for over fifty years: COBOL COBOL, 55 years old and still in its youth, not ever thinking about retirement, has become a nuisance, something everyone wants to get rid ...

The goal is to describe relationships among people and systems at work in the DevOps world and discuss approaches to making systems more transparent (to coders and non-coders!).   The Trusted Image Organizations like Amazon, Canonical, and Red Hat provide virtual machine images of popular operating system distributions. It’s common to launch these images directly “as-is” and install software onto them after launch. However, there are advantages to specializing one (or several) of these images and using ...
