There is only one true way (the proper way) to program. Just as there is only one “reality”, one “truth” (which correctly describes What Is) and The Right Way (of the Buddha, which means being firmly grounded in What Is). Imagine, if you will, that you are writing a program for yourself which will trade your own life savings on some “exchange”. Not for other people, not other people’s money. You for yourself....
I finally found a well-written no-bullshit book about CS. It says, among other things: There is no need to define a representation of the values False and True in terms of values of some other type. Conceptually, values of type Bool are simply (denoted by) the expressions False and True. Of course, the computer’s internal representation of Bool and all other data is in terms of bits, but we don’t need to know any of the details of how that works to write programs....
A small disclaimer: I’ve lived in India for a few years, I have some good friends there and I think I begin to really understand the some cultural aspects which govern this vastly complex and spontaneous society. Nowadays everyone, it seems, is either a programmer or an AI researcher or both. When they are not a crapto “engineers”, of course. Just like chef Gusteau from the Ratatouille movie famously proclaimed – “Anyone can cook”....
AUTHOR: <lngnmn2@yahoo.com> First of all, abstraction barriers are very real (not merely abstract notions) and they are liteterally everywhere (at all levels, from molecular to social). The “most real” abstraction barrier is how what we call “atoms” are “used” by molecular (cell) biology. For cells atoms are is how ancient people used to conceptualize them - an atom is indivisible, indestructive, eternal, “just is”. More precisely, cell biology “is not concerned” with what atoms “really are” and use them as an abstraction, provided that there is no one to “see this”, aside from an “higher level” intelligent observer....
Emacs is a monument (just like Potala palace in Lhasa) of an old-school software engineering and classic languages – it is, indeed, a world heritage site of the golden age of programming. It also could be compared with the ghat complex of Varanasi, which began no one knows when and is constantly changing since then, being reshaped by the “waves” and “tides” of social dynamics. Visiting Emacs is like visiting one of such historic sites, and just like them, it has been re-shaped by the successions of mass-hysteria and zealous over-excitement about bullshit....
The Rust programming language has been hyped as a system programming language, which implies that it has to have an explicit “access” to the hardware-level abstractions, such as the Stack, the Heap and the Procedures, together with the operating system-level abstractions, such as following the particular calling conventions (a set of standardized interfaces) for an “arch and OS /duo”, and to be “aware of” the ABIs in general. Overview Rust is, in principle, an imperative language....
