I am specifically asking about software and needed libraries, not stuff like Wikipedia or the writings of Ernest Hemmingway.
To keep people from archiving all of github on thousands of shucked external hard drives cobbled together all Frankenstein-y to create a postapocalyptic data center assume a ~1TB storage limitation. Though I’m sure that person exists here on Lemmy somewhere :D
As a base: The Linux kernel source, GNU software sources and compiler binaries so I can - in theory - write missing software myself. For convenience probably some stable, offline-installable, ready to use distros.
I would probably also archive sources and binaries of day-to-day software like web-browsers (I might still have an intranet to use), office tools, photo management software, audio/video players and all the codecs, etc.
I think that’s a solid starting point but im sure I’m missing something important :D
I’d also keep DNS, DHCP and routing software,detailed manuals about how IPV4 and 6 work, nginx and maybe Wordpress, lemmy, Peertube, and other federated software
Good point! And Docker. Also: Encryption software
