We don’t have much trouble yet with relativistic temporal distortions, but Earth’s motion causes us to lose about 0.152 seconds per year relative to the Solar system. Likewise we lose about 8.5 seconds per year relative to the Milky Way. I wonder when we’re going to start to care. Presumably there would be consideration of such issues while dealing with interplanetary spacecraft, timing burns and such.

Brush of the dyxlesia as well evidently.

Not at all, just a bit of word play. It's "officially" a meme even! Cheers

Here is the three original Postscript Books. They are the classic way to learn PS.

The Blue Book (Tutorial and Cookbook) https://archive.org/details/postscriptlangua0000unse

The Red Book (Language Reference) https://archive.org/details/postscriptlangua0000unse_l1h3

The Green Book (Language Design) https://archive.org/details/PSGreenBook

Haha! I used to do LOTS of work in PostScript. The biggest project was a system which was part Python for the management, but PS for the content of a database publishing engine, motivated by the the need to generate crazily complicated real estate books, back in the day. There was a whole huge template system for different kinds of commercial and residential property and all sorts of different sections, ranges and indices. It was responsible for generating hundreds of multi-hundred page documents per day for dozens of real estate boards across Western Canada. Each publication was about as complicated as a Yellow Pages and generated daily and automatically from ever-changing data. In fact, the underlying database schema could evolve automatically through the update mechanisms in RETS (the Real Estate Transaction System API), though that was on the Python side. The rendering happened using GhostScript out to PDF for printing and electronic distribution to realtors. A stupid amount of detail, but what else is a touch of the 'tsim for anyway?!?

My other PostScript stuff was mostly fun and experimental: some fractal hacks which made printers and typesetters groan and some collaborative knowledge visualization stuff. I got started with PostScript on my NextStation in 1991 and it served me well, being the basis of a whole career of programmatic visualization.

As a language it is lovely, if you're a fan of minimalism -- being stack-happy, like FORTH. It is well worth learning even just to flex the mind, but especially if you need to make complex diagrams and value stable APIs.

Check out Kroki for a multi-syntax wrapper around a bunch of text driven diagram generators —- including Mermaid, PlantUML, Ditaa, GraphViz, SVGBob, etc, etc

Same with android phones - a super-specific hardcoded phrase is much easier to work in the power budgets required for an "always on" part of the device.

It's why a manufacturer (like Samsung) can change that sort of thing on their devices, but it's not realistically something an end user (or even an app) can customize in software. It's not some "arbitrary" limitation.

Back in 1992 or so the NeXT could distinguish (was it 16 or) 64 fixed, trained, phrases. Point being, it doesn’t take too much compute with a finite vocabulary.

I've gravitated to the use of a 43" 4K TV as my main monitor (and have a few others scattered about for auxiliary purposes) and when hacking hard have a full screen emacs window split into lots of panes, vertically and horizontally a la Mondrian. I am confused about how others get anything done without a similar configuration! This new feature seems like it will be great fun.

Oh yeah, and I generally keep such a monster running in a GNU screen via mosh on servers too. Loverly! They can run for years.
