Bit Rot is In Your Future

If you are over the age of 55 or 60 you may well have some 8-track cassettes still stashed in the trunk (or boot if you’re a Brit) of your car. If you’re over 50 it’s possible that you may have some old floppy disks or regular music cassettes stored in a bottom drawer. If you’re over 40 you’re likely to have boxes of old VHS tapes and crate-loads of CDs (or even laser disks) under your bed. So, if you fall into one of these categories most of the content memorized on any of these media types is now very likely to be beyond your reach — your car (hopefully) does not have an 8-track player; you dumped your Sony Walkman for an iPod; and your CDs have been rendered obsolete by music that descends to your ears from the “cloud”.

[Of course, 45s and 33s still seem to have a peculiar and lasting appeal — and thanks to the analog characteristics of vinyl the music encoded in the spiral grooves is still relatively easily accessible. But this will be the subject of another post].

So our technological progress, paradoxically, comes at a cost. As our technologies become simpler to use and content becomes easier to construct and disseminate, it becomes “bit rot” for future generations. That is, our digital present will become lost to more advanced technologies in the future. One solution would be to hold on to your 8-track player. But, Vint Cerf, currently a VP at Google and one of the founding fathers of the internet, has other ideas.

From the Guardian:

Piles of digitised material – from blogs, tweets, pictures and videos, to official documents such as court rulings and emails – may be lost forever because the programs needed to view them will become defunct, Google’s vice-president has warned.

Humanity’s first steps into the digital world could be lost to future historians, Vint Cerf told the American Association for the Advancement of Science’s annual meeting in San Jose, California, warning that we faced a “forgotten generation, or even a forgotten century” through what he called “bit rot”, where old computer files become useless junk.

Cerf called for the development of “digital vellum” to preserve old software and hardware so that out-of-date files could be recovered no matter how old they are.

“When you think about the quantity of documentation from our daily lives that is captured in digital form, like our interactions by email, people’s tweets, and all of the world wide web, it’s clear that we stand to lose an awful lot of our history,” he said.

“We don’t want our digital lives to fade away. If we want to preserve them, we need to make sure that the digital objects we create today can still be rendered far into the future,” he added.

The warning highlights an irony at the heart of modern technology, where music, photos, letters and other documents are digitised in the hope of ensuring their long-term survival. But while researchers are making progress in storing digital files for centuries, the programs and hardware needed to make sense of the files are continually falling out of use.

“We are nonchalantly throwing all of our data into what could become an information black hole without realising it. We digitise things because we think we will preserve them, but what we don’t understand is that unless we take other steps, those digital versions may not be any better, and may even be worse, than the artefacts that we digitised,” Cerf told the Guardian. “If there are photos you really care about, print them out.”

Ancient civilisations suffered no such problems, because histories written in cuneiform on baked clay tablets, or rolled papyrus scrolls, needed only eyes to read them. To study today’s culture, future scholars would be faced with PDFs, Word documents, and hundreds of other file types that can only be interpreted with dedicated software and sometimes hardware too.

The problem is already here. In the 1980s, it was routine to save documents on floppy disks, upload Jet Set Willy from cassette to the ZX spectrum, slaughter aliens with a Quickfire II joystick, and have Atari games cartridges in the attic. Even if the disks and cassettes are in good condition, the equipment needed to run them is mostly found only in museums.

The rise of gaming has its own place in the story of digital culture, but Cerf warns that important political and historical documents will also be lost to bit rot. In 2005, American historian Doris Kearns Goodwin wrote Team of Rivals: the Political Genius of Abraham Lincoln, describing how Lincoln hired those who ran against him for presidency. She went to libraries around the US, found the physical letters of the people involved, and reconstructed their conversations. “In today’s world those letters would be emails and the chances of finding them will be vanishingly small 100 years from now,” said Cerf.

He concedes that historians will take steps to preserve material considered important by today’s standards, but argues that the significance of documents and correspondence is often not fully appreciated until hundreds of years later. Historians have learned how the greatest mathematician of antiquity considered the concept of infinity and anticipated calculus in 3BC after the Archimedes palimpsest was found hidden under the words of a Byzantine prayer book from the 13th century. “We’ve been surprised by what we’ve learned from objects that have been preserved purely by happenstance that give us insights into an earlier civilisation,” he said.

Researchers at Carnegie Mellon University in Pittsburgh have made headway towards a solution to bit rot, or at least a partial one. There, Mahadev Satyanarayanan takes digital snapshots of computer hard drives while they run different software programs. These can then be uploaded to a computer that mimics the one the software ran on. The result is a computer that can read otherwise defunct files. Under a project called Olive, the researchers have archived Mystery House, the original 1982 graphic adventure game for the Apple II, an early version of WordPerfect, and Doom, the original 1993 first person shooter game.

Inventing new technology is only half the battle, though. More difficult still could be navigating the legal permissions to copy and store software before it dies. When IT companies go out of business, or stop supporting their products, they may sell the rights on, making it a nightmarish task to get approval.

The Future Tubes of the Internets

CerfKahnMedalOfFreedom

Back in 1973, when computer scientists Vint Cerf and Robert Kahn sketched out plans to connect a handful of government networks little did they realize the scale of their invention — TCP/IP (a standard protocol for the interconnection of computer networks. Now, the two patriarchs of the Internet revolution — with no Al Gore in sight — prognosticate on the next 40 years of the internet.

From the NYT:

Will 2014 be the year that the Internet is reined in?

When Edward J. Snowden, the disaffected National Security Agency contract employee, purloined tens of thousands of classified documents from computers around the world, his actions — and their still-reverberating consequences — heightened international pressure to control the network that has increasingly become the world’s stage. At issue is the technical principle that is the basis for the Internet, its “any-to-any” connectivity. That capability has defined the technology ever since Vinton Cerf and Robert Kahn sequestered themselves in the conference room of a Palo Alto, Calif., hotel in 1973, with the task of interconnecting computer networks for an elite group of scientists, engineers and military personnel.

The two men wound up developing a simple and universal set of rules for exchanging digital information — the conventions of the modern Internet. Despite many technological changes, their work prevails.

But while the Internet’s global capability to connect anyone with anything has affected every nook and cranny of modern life — with politics, education, espionage, war, civil liberties, entertainment, sex, science, finance and manufacturing all transformed — its growth increasingly presents paradoxes.

It was, for example, the Internet’s global reach that made classified documents available to Mr. Snowden — and made it so easy for him to distribute them to news organizations.

Yet the Internet also made possible widespread surveillance, a practice that alarmed Mr. Snowden and triggered his plan to steal and publicly release the information.

With the Snowden affair starkly highlighting the issues, the new year is likely to see renewed calls to change the way the Internet is governed. In particular, governments that do not favor the free flow of information, especially if it’s through a system designed by Americans, would like to see the Internet regulated in a way that would “Balkanize” it by preventing access to certain websites.

The debate right now involves two international organizations, usually known by their acronyms, with different views: Icann, the Internet Corporation for Assigned Names and Numbers, and the I.T.U., or International Telecommunication Union.

Icann, a nonprofit that oversees the Internet’s basic functions, like the assignment of names to websites, was established in 1998 by the United States government to create an international forum for “governing” the Internet. The United States continues to favor this group.

The I.T.U., created in 1865 as the International Telegraph Convention, is the United Nations telecommunications regulatory agency. Nations like Brazil, China and Russia have been pressing the United States to switch governance of the Internet to this organization.

Dr. Cerf, 70, and Dr. Kahn, 75, have taken slightly different positions on the matter. Dr. Cerf, who was chairman of Icann from 2000-7, has become known as an informal “Internet ambassador” and a strong proponent of an Internet that remains independent of state control. He has been one of the major supporters of the idea of “network neutrality” — the principle that Internet service providers should enable access to all content and applications, regardless of the source.

Dr. Kahn has made a determined effort to stay out of the network neutrality debate. Nevertheless, he has been more willing to work with the I.T.U., particularly in attempting to build support for a system, known as Digital Object Architecture, for tracking and authenticating all content distributed through the Internet.

Both men agreed to sit down, in separate interviews, to talk about their views on the Internet’s future. The interviews were edited and condensed.

The Internet Ambassador

After serving as a program manager at the Pentagon’s Defense Advanced Research Projects Agency, Vinton Cerf joined MCI Communications Corp., an early commercial Internet company that was purchased by Verizon in 2006, to lead the development of electronic mail systems for the Internet. In 2005, he became a vice president and “Internet evangelist” for Google. Last year he became the president of the Association for Computing Machinery, a leading international educational and scientific computing society.

Q. Edward Snowden’s actions have raised a new storm of controversy about the role of the Internet. Is it a significant new challenge to an open and global Internet?

A. The answer is no, I don’t think so. There are some similar analogues in history. The French historically copied every telex or every telegram that you sent, and they shared it with businesses in order to remain competitive. And when that finally became apparent, it didn’t shut down the telegraph system.

The Snowden revelations will increase interest in end-to-end cryptography for encrypting information both in transit and at rest. For many of us, including me, who believe that is an important capacity to have, this little crisis may be the trigger that induces people to spend time and energy learning how to use it.

You’ve drawn the analogy to a road or highway system. That brings to mind the idea of requiring a driver’s license to use the Internet, which raises questions about responsibility and anonymity.

I still believe that anonymity is an important capacity, that people should have the ability to speak anonymously. It’s argued that people will be encouraged to say untrue things, harmful things, especially if they believe they are anonymous.

There is a tension there, because in some environments the only way you will be able to behave safely is to have some anonymity.
