Vector Calculus by Marsden is a very good book for getting a grasp of the meaning and application of basic concepts such as Poisson and Langrange equations, and Maxwell equations. You will see that in R^3 those concepts can be represented graphically.
when I disable websocket with network.websocket.max-connections = 0, then whatsappweb doesn't work, so perhaps someone can develop a related attack here?
You are right, wikipedia: According to Apple Confidential by Owen W. Linzmayer, the original code name for the Dylan project was Ralph, for Ralph Ellison, author of the novel Invisible Man, to reflect its status as a secret research project.
Ralph was the initial name of the project, from the film the invisible man. More about dylan history:(1)
Ralph used prefix notation, dylan infix notation. Here you can find an implementation of ralph:(2)
From (2): Ralph is a Lisp-1 dialect that compiles to JavaScript. It is heavily inspired by an early version of Dylan (also known as "Prefix Dylan"), as described in Dylan – An object-oriented dynamic language.
Also (3) is about a Lisp to Dylan translator. There is also norvig lisp to dylan translator cited in (3).
