…if you’re into paper books (and a hefty table) the DK complete world atlas includes a lot of geographic information, or if you prefer a dryer, more-authoritative presentation, the times world atlas is the grandaddy of the format…

…it looks like DK also offers a digital version of their previous editon…

(i have the millenium editions of both atlases, and they’re both fantastic tomes, but i think the DK complete atlas is more of what you’re looking for)

…that’s the POWER model: the unit posted above is the consumer version with the SX chip, no math coprocessor and fewer function keys…

…NeXTstep was built on mach and, although i’m unsure if any antecedents remain in macOS, it was certainly production-ready in its day; i remember a couple of decades ago there were stopgap versions of the HURD built on top of mach instead of their own microkernel but i thought that was only ever intended as a temporary workaround…

…i presume on that basis that sustained developer interest was its greatest hurdle, no pun intended…

edit: …is this the post-mortem you mentioned?..

…i’m absolutely ignorant of its current state, but every time i’ve checked in on progress of GNU/hurd over the past three decades, it still hasn’t matured into a stable production-ready platform: i’m not sure if that’s an artifact of technical viability or developer interest…
