Appropriate technology, rule of least power, and minimal computing

Thanks to Ed Summers for sharing his presentation for iPres2020! In it, he covers many things, including significant properties in relation to designated communities, preservation through desiccation, and the Principle of Least Power (Rule of Least Power) in relation to minimal computing. For folks working with technologies that need to be sustained, and so need to be maintainable as they grow as with digital libraries and collections, ideas like minimal computing, the Rule of Least Power, and appropriate technology are foundational concepts.
