The idea of using laser interferometer for detecting gravitational waves was first proposed in 1962 (shortly after inventing lasers) by M. Gertsenshtein and V. Pustovoit [1]. So it took more than 50 years from the idea to its implementation

Covariance can be thought of as a mechanism for overriding functions. Assume there is a (base) function f: X -> Y We want to override it by providing a new mapping from U to V: f: U -> V This mechanism is said to be

It could be a technological (column-oriented) alternative to what map-reduce in general and Spark with RDDs in particular are doing. It might be easier to define a data processing workflow as a number of column definitions rather than as

(I can be wrong but) as far as I understand E is based on objects and messages as primary mechanisms, that is, we do not know where objects exist, how they are managed and how messages are transferred. Concept-oriented programming (COP) is

Would like to mention concept-oriented programming [1] which is work in progress but has highly ambitious goals of changing the way we think of programming. The initial idea is to make references active and customized elements of the pr

The author focuses on the algorithmic and computational aspects of programming. Yet, nowadays programming is much more than this beautiful classical view on programming. Programming is more about describing a complex system by taking into

What they describe is actually (very) shallow feature engineering and these methods have been used for decades. These techniques can hardly help in really difficult data analysis tasks where abstract features need to be either manually defi

Concept-oriented programming http://conceptoriented.org . Not a language yet but an attempt to generalize OOP. It introduces concepts instead of classes and inclusion instead of inheritance.

Nowadays BI has (at least) two sides: visual analytics, and data wrangling. There are many tools aimed at visualization. But there is a lack of tools for easy data wrangling. I have been working on such a data wrangling tool, called Data Co
