When Gosling was at Sun, he was one of two principal architects of the NeWS Window system. The X Window system was designed for "dumb" display devices and so the display elements were all static, not requiring much work from the server. NeWS was designed to run on a (Sun) workstation, where there was a lot of computational power available, so it was based on Postscript. A NeWS client would send a program to the server, not just static commands.

Gosling, unsurprisingly, designed Java with the NeWS model in mind, where web pages were programs, not just static HTML documents. When I got him to sign my copy of "The Java Programming Language", I asked him if Java was the revenge of NeWS. He just smiled.

The corollary of this was Display PostScript. At my first job we had a SPARCStation 2 with a SPARCprinter. The SPARCStation was a mighty wonder to behold, with a storage pedestal and a lovely OpenWindows GUI on a luxurious Sun monitor and color framebuffer. The operator sitting at the desk was often just a novice clerical worker, but we ran a few Internet services on the machine as well. However, our department depended on that SPARCprinter to spit out hundreds of sheets of paper daily.

We could not depend on the printer to stay functional, though. Have you heard of a Winmodem? SPARCprinters were essentially that: they were configured as a "dumb display device" where all the imaging logic was contained in the software and run on the server. A page was written in PostScript, rendered on the print server, and dispatched to the printer as if it were a framebuffer/monitor.

Unfortunately, for whatever reason, the server software was not so reliable, or the printer hardware wasn't reliable, and because of this peculiar symbiotic parasitism, whenever our printer wedged, our server was also toast. Every process went into "D" for device wait; load averages spiked and all our work ground to a halt. We would need to pull the worker off the desktop, reboot the whole server, and start over with the printer.

That printer haunted my dreams, all though my transition from clerk, to network operator, to sysadmin, and it wasn't until 2011 when I was able to reconcile with printers in general. I still miss SunOS 4 and the whole SPARC ecosystem, but good riddance to Display PostScript.

Just as we have a modern successor to X in Wayland, we also have a modern successor to NeWS: the browser with JavaScript, with PWAs and Electron providing a smoother desktop integration.

I wonder what Gosling thinks of the fact that NeWS ultimately won in the end, even on Microsoft systems.
