Like others[1] I was saddened that Mac's Preview program stopped opening .ps/.eps files with the release of Ventura in late 2022. I never understood exactly why; I guess security issues around the PostScript interpreter. But that made it lot less convenient to hack around in .ps files. Ghostscript's interactive display program(s?) never seemed as convenient as Preview.

Still, this book is awesome and I've been inspired by it for awhile. I used to love whipping up diagrams and simple vector art in .ps/.eps files. In a fit of procrastination in ~2006 I created a minimalist horizontal rule for an IEEE conference submission, and that diamondrule.eps[2] has now become the standard. I would say that EPS is still more convenient than SVG as a format to contain, in one self-contained file, raster graphics with overlaid vector graphics.
