(From )The big feature is that the VM and emulation can be loaded from a network server. That virtual machine then runs the old operating system and application. Llustration: Nicholas Little Layers of Abstraction: Olive requires many layers of software abstraction to create a suitable virtual machine. The new work adds yet more levels of indirection (“ We can solve any problem by introducing an extra level of indirection.“, per David Wheeler) This fall Mahadev Satyanarayanan of CMU writes about a improved system for creating this kind of VM emulation for old software. This isn’t a complete reproduction, but it’s a lot more than reading source code. With a VM running an emulator, it can be possible to actually run old code, long after the original system is gone. In recent years, archivists have been making heavy use of virtual machine technologies.

How much of that hardware and software can be preserved for future historians? And how? Possible or not, it is NARA’s job to archive it for the future. Think about it: the most important historic event of the twentieth century was the first moon landing. By now, there is not only digital records, but also software artifacts. In the US, the National Archives is tasked to preserve artifacts of “historical importance” (with the goal of preserving them for the “life of the Republic”-at least a century more). Contemporary efforts such as The Software Preservation Network (SPN) and The Internet Archive Software Collection are amassing collections of old source code. Librarians and archivists have been worrying and working on it for a couple of decades now.

These questions would be rather difficult to examine such analysis even with the source code (in IBM 360 assembler). It would be intriguing to discover influences and idioms that might be seen in the coding style. The result isn’t in question these days (it has been proved many times), but it certainly would be interesting to examine the original proof to see how it was coded, what the programmers “knew”, or if there were errors. The four color map problem was proved in 1976 with a computer assisted argument. This problem is even more acute in smaller niches, such as science. So this seminal phenomenon which led to so many descendants and created a whole conceptual category (“first person shooter”) is almost beyond reach of history. Could a historian recreate the experience? Not likely. Is there a record of that? Of course not. For example, I remember the first time I played Doom (it didn’t really interest me). This means that much of the history of digital culture is difficult to reconstruct. For another, the life time of software and hardware is short, so old stuff is soon gone. For one thing, the actual experience of digital life, what you really see and do, is not generally recorded. Worse, every mistake and lie may live forever, no matter how many times it is corrected or refuted.Īt the same time, many aspects of digital life are gone within seconds or days. We all have learned that anything you do on line may pop up years or decades later.

The digital world is a weird combination of ephemeral and eternal.
