Object oriented programming has since been shown to be a mistake??! That's NeWS to me. Can you provide a citation please?

What do you mean that NeWS or PostScript classes are not extensible? The little "e" in NeWS stands for "extensible".

And what is the correct number of stacks, in your opinion?

Please quantify what you can, and provide examples and links to code, and citations of other people who agree with your personal opinions like the number of stacks a language is supposed to have, the meaning of extensibility, or that object oriented programming languages are a mistake.

> The little "e" in NeWS stands for "extensible".

But maybe that capital N is for Non .. (kidding obviously)

I've always been curious about NeWS but the web is quite short of demos about it (not helped by newspapers called Sun either). Do you know sites with videos about it ?

[DonHopkins]

Thanks for asking! ;) I've put up some old demos on youtube, and made illustrated transcriptions of some, and written some papers and articles. Sorry the compression is so terrible on some of the videos. Here are some links:

SimCity, Cellular Automata, and Happy Tool for HyperLook (nee HyperNeWS (nee GoodNeWS)). HyperLook was like HyperCard for NeWS, with PostScript graphics and scripting plus networking. Here are three unique and wacky examples that plug together to show what HyperNeWS was all about, and where we could go in the future!

If you can find a library copy, The NeWS Book (e.g. https://www.waterstones.com/book/the-news-book/james-gosling...) might also be of interest for a static view, but I don't know how much was actually implemented, and I'm away from my copy.

I haven't had a chance to look at the videos for old time's sake, and they may make the point: a big part of it, as a developer experimenting with things, was the mode-less Smalltalk-like environment which allowed you to modify the system on the fly. (I don't know how much like, since I never used Smalltalk.)

Edit: "Scott McNealy ate my window system" :-(

Here it is!

The ability to "psh" to the NeWS server and play around with PostScript (much like the Chrome Developer Tools now lets you do with JavaScript) was crucial to making NeWS fun.

The PSIBER Space Deck was trying to make a visual Smalltalk-like or Lisp-Machine-like development and debugging environment for NeWS, that let you visually browse and edit PostScript code and data structures and objects and processes in the system.

The Shape of PSIBER Space: PostScript Interactive Bug Eradication Routines — October 1989

Written by Don Hopkins, October 1989. University of Maryland Human-Computer Interaction Lab, Computer Science Department, College Park, Maryland 20742.

Abstract

The PSIBER Space Deck is an interactive visual user interface to a graphical programming environment, the NeWS window system. It lets you display, manipulate, and navigate the data structures, programs, and processes living in the virtual memory space of NeWS. It is useful as a debugging tool, and as a hands on way to learn about programming in PostScript and NeWS.

Here's some fun stuff about NeWS and screen snapshots of the HyperTies hypermedia browser and Emacs authoring tool that I scanned (after printing them out as slides for a talk, then losing the original images) -- HyperTIES supported formatted hypertext, raster, and PostScript graphics, with plug-in extensible interactive "applets" programmed in PostScript, including pie menus, pop-up embedded image targets, widgets, form controls, scrolling text editors, etc. These screen snapshots were slides for a talk about building user interfaces in NeWS, using HyperTIES to explain and demonstrate itself and the technology it was implemented with:

And here are some ideas about visual programming and programming by demonstrations that I was thinking about while developing PSIBER, like a visually programmable window shell environment:

Oh yeah some are compressed to death. But most are ok. The precision pie curved lever was mindblowing, and I've seen some !

This should be a top-level article.

Yeah, I'd say GUI development is one of the places OOP really shines. I think a lot of the OOP was a mistake opinions come from its ubiquitous use in the enterprise, even in domains for which it was not well suited.

[nineteen999]

I would venture game development as well - UE4's actor and component model is a good example of this, it's a very flexible system that allows you to strike a good balance between inheritance and composition.
