Apparently my account on the site is/was now more than a quarter of a century old... Gonna try to avoid thinking on that too deeply. :D
There's been a non-zero number of occasions since that time where I've observed situations that mirror the trust-based challenges Advogato sought to solve.
It is perhaps telling that as prescient as Raph's work on trust metrics was he later moved on to the notoriously challenging realm of font rendering--presumably because it seemed more tractable. :D
I encountered the Sony MMCD when I fell down a rabbit hole *checks literal notes* around five years ago while researching Microsoft Encarta MindMaze[0] and its related file formats.
It turns out the data associated with MindMaze (& other encyclopedia data) changed storage format over subsequent releases of Encarta and these changes provide some interesting historical insights--including that if MS had had its way we'd all be writing web pages in RTF rather than HTML[1]. :D
You may ask, "What connection does this have to the Sony MMCD?".
Well, one of the storage formats used with early Encarta data is `.mvb` which is a format used by Microsoft Multimedia Viewer[2] (also known by multiple other names--none of which are any easier to web search :D ).
And, it turns out, "Multimedia Viewer could compile titles for Tandy Video Information System and other Modular Windows systems, as well as Sony Multimedia CD-ROM Player, a portable MS-DOS-based CD-ROM XA reader released in 1992."[2][3]
According to my research the tool "...includes software tools that simulate the look and feel of the Sony player titles on a PC" which is interesting in the context of the emulator for the Discman mentioned in the original post.
Anyway, that's the very short version of the rabbit hole--maybe in another five years I'll get around to writing up the rest...
Oh, sure, rpath/runpath shenanigans will work in some situations but then you'll be tempted to make such shenanigans work in all situations and then the madness will get you...
To save everyone a click here are the first two bullet points from Exhibit A:
* If an executable has `RPATH` (a.k.a. `DT_RPATH`) set but a shared library that is a (direct or indirect(?)) dependency of that executable has `RUNPATH` (a.k.a. `DT_RUNPATH`) set then the executable's `RPATH` is ignored!
* This means a shared library dependency can "force" loading of an incompatible [(for the executable)] dependency version in certain situations. [...]
Further nuances regarding LD_LIBRARY_PATH can be found in Exhibit B but I can feel the madness clawing at me again so will stop here. :)
I vaguely wondered if FreeHand would make an appearance in this thread. :)
Two features that come to mind as IIRC being unique (as compared to Illustrator) were multi-page documents and multiple page size multi-page documents. Ideal for the complete standard set of company branded print documents: business card, "With Compliments" slip, and letterhead. :D
Adobe's acquisition of Macromedia and subsequent killing of (the IMO superior) FreeHand contributed directly to my subsequent decision to avoid closed source application software--especially for creative tools--even if alternatives were "technically inferior".
(And, indeed, "creative tool killed/hampered for business reasons" is a story which has been repeated elsewhere multiple times in the quarter century[0] since.)
While Inkscape is still missing features compared to FreeHand it is however also still here many years later and is what I've used ever since when I need 2D vector design software. (Although I've also been keeping an eye on Graphite: https://graphite.rs)
(Always nice to see decade old effort still get referenced on occasion. :) )
