Cyberarcheology
Much like humanity, the yinrih's information age dawned around the same time they achieved spaceflight. Through the millennia their internetwork has grown in size and complexity as they settled throughout Focus, and by the time of First Contact they have amassed 95 thousand Earth years of digital information.
When you live over 700 years, you have to think long-term. There are data centers filled with storage servers that are built to operate independently for millennia. To err is vulpithecine, and sometimes these servers are left forgotten to run on their own.
The discipline of cyberarcheology specializes in ferreting out these lost archeonets and uncovering their secrets. Cyberarcheologists specialize in dead programming languages, obsolete data storage formats, outmoded hardware architectures, and long superseded network protocols.
The Farspeakers have a keen interest in cyberarcheology as they want to preserve the system their predecessors built. There is also a thriving amateur cyberarcheology community whose interests range from finding lost media from one's own puppyhood to preserving vintage tech from before the end of the Terran ice age.
