My colleague Patrick, co-worker at OST (Python track) is flying out to New England to preach 2.x in company already using it and with no plans to ever upgrade. Mostly we both teach Python 3, e.g. for ONLC. They (the NH company) have a working machine, imagine a Victorian steam engine that doesn't break, and see no point whatsoever in moving to 3.x just for the hell of it (unlike Instagram, which made the leap and now advises others on how it's doable). On the other hand, teachers and developers are expected to be up on the latest, so I feel compelled to write little scripts using asyncio (see link below). We have different use communities. In science fiction, I imagine some venerable companies two hundred years from now still running some 2.x engine on a dedicated emulator, because it works and people are smarter in the future and spend less time fixing what's not broken. The business of this NH company has nothing to do with software directly. Imagine a dedicated box that just prints invoices on a particular device, and that's it. It's like a micro-controller or micro-service. We still have bacteria running the same DNA after a billion years, don't we? I'm still a tad confused on the Sage / on-line Jupyter Notebook situation, was surprised to see the kernel names other than vanilla Python 2.x / 3.x and instead seeing SAGE Python 2.7 and Anaconda 3.6 or whatever I saw. Jorge starts right off using not-Python-syntax I thought I witnessed, because Sage is somehow present on bootup? I booted up that cloud service myself and tried some stuff. Still scratching my head. Peter, do you use this service too? I do teach Jupyter Notebooks as a part of my Python classes. Getting students to realize they can run a web server locally and serve themselves, no need for the Internet, is a number one priority, after which JN makes more sense. Boot a web server, have your browser run some Javascript with JSON, and you're in business. JN as a front end to pandas is like Office on steroids, with web server Word and multi-dimensional Excel.
