Thursday 9-14
Write two or more sentences responding to Koan 6.
Koan 6: Nothing Goes Away
That is the number of bits that were created and stored away in 2007,

according to one industry estimate. The capacity of disks has followed its own version of Moore’s Law, doubling every two or three years. For the time being at least, that makes it possible to save everything though recent projections suggest that by 2011, we may be producing more bits than we can store.

In financial industries, federal laws now require massive data retention, to assist in audits and investigations of corruption. In many other businesses, economic competitiveness drives companies to save everything they collect and to seek out new data to retain. Wal-Mart stores have tens of millions of transactions every day, and every one of them is saved—date, time, item, store, price, who made the purchase, and how—credit, debit, cash, or gift card. Such data is so valuable to planning the supply chain that stores will pay money to get more of it from their customers. That is really what supermarket loyalty cards provide—shoppers are supposed to think that the store is grant- ing them a discount in appreciation for their steady business, but actually the store is paying them for information about their buying patterns. We might better think of a privacy tax—we pay the regular price unless we want to keep information about our food, alcohol, and pharmaceutical purchases from the market; to keep our habits to ourselves, we pay extra.
The massive databases challenge our expectations about what will happen to the data about us. Take something as simple as a stay in a hotel. When you check in, you are given a keycard, not a mechanical key. Because the key- cards can be deactivated instantly, there is no longer any great risk associ- ated with losing your key, as long as you report it missing quickly. On the other hand, the hotel now has a record, accurate to the second, of every time you entered your room, used the gym or the business center, or went in the back door after-hours. The same database could identify every cocktail and steak you charged to the room, which other rooms you phoned and when, and the brands of tampons and laxatives you charged at the hotel’s gift shop. This data might be merged with billions like it, analyzed, and transferred to the parent company, which owns restaurants and fitness centers as well as hotels. It might also be lost, or stolen, or subpoenaed in a court case.
The ease of storing information has meant asking for more of it. Birth cer- tificates used to include just the information about the child’s and parents’ names, birthplaces, and birthdates, plus the parents’ occupations. Now the electronic birth record includes how much the mother drank and smoked dur- ing her pregnancy, whether she had genital herpes or a variety of other med- ical conditions, and both parents’ social security numbers. Opportunities for research are plentiful, and so are opportunities for mischief and catastrophic accidental data loss.
And the data will all be kept forever, unless there are policies to get rid of it. For the time being at least, the data sticks around. And because databases are inten- tionally duplicated—backed up for security,
The data will all be kept forever, unless there are policies to get rid of it.


or shared while pursuing useful analyses—it is far from certain that data can ever be permanently expunged, even if we wish that to happen. The Internet consists of millions of interconnected computers; once data gets out, there is no getting it back. Victims of identity theft experience daily the distress of having to remove misinformation from the record. It seems never to go away.

Gordon Moore, founder of Intel Corporation, observed that the density of integrated circuits seemed to double every couple of years. This observation is referred to as “Moore’s Law.” Of course, it is not a natural law, like the law of gravity. Instead, it is an empirical observation of the progress of engineering and a challenge to engineers to continue their innova- tion. In 1965, Moore predicted that this exponential growth would continue for quite some time. That it has continued for more than 40 years is one of the great marvels of engineering. No other effort in his- tory has sustained anything like this growth rate.

The speed of a computer is usually measured by the number of basic operations, such as additions, that can be performed in one second. The fastest computers available in the early 1940s could perform about five operations per second. The fastest today can perform about a trillion. Buyers of personal comput- ers know that a machine that seems fast today will seem slow in a year or two.
For at least three decades, the increase in processor speeds was exponential. Computers became twice as fast every couple of years. These increases were one conse- quence of “Moore’s Law” (see side- bar).
Since 2001, processor speed has not followed Moore’s Law; in fact, processors have hardly grown faster

at all. But that doesn’t mean that computers won’t continue to get faster. New chip designs include multiple processors on the same chip so the work can be split up and performed in parallel. Such design innovations promise to

achieve the same effect as continued increases in raw processor speed. And the same technology improvements that make computers faster also make them cheaper.
The rapid increase in processing power means that inventions move out of labs and into consumer goods very quickly. Robot vacuum cleaners and self- parking vehicles were possible in theory a decade ago, but now they have become economically feasible. Tasks that today seem to require uniquely human skills are the subject of research projects in corporate or academic lab- oratories. Face recognition and voice recognition are poised to bring us new inventions, such as telephones that know who is calling and surveillance cameras that don’t need humans to watch them. The power comes not just from the bits, but from being able to do things with the bits.

Koan 3 is about how we lose information, even digital information for different reasons. Do you agree?  Can you think of examples?  Will storage devices go away?  Will we always have CDs?

Koan 3: There Is Want in the Midst of Plenty
Vast as world-wide data storage is today, five years from now it will be ten times as large. Yet the information explosion means, paradoxically, the loss of information that is not online. One of us recently saw a new doctor at a clinic he had been using for decades. She showed him dense charts of his blood chemistry, data transferred from his home medical device to the clinic’s computer—more data than any specialist could have had at her disposal five years ago. The doctor then asked whether he had ever had a stress test and what the test had shown. Those records should be all there, the patient explained, in the medical file. But it was in the paper file, to which the doc- tor did not have access. It wasn’t in the computer’s memory, and the patient’s memory was being used as a poor substitute. The old data might as well not have existed at all, since it wasn’t digital.
Even information that exists in digital form is useless if there are no devices to read it. The rapid progress of storage engineering has meant that data stored on obsolete devices effectively ceases to exist. In Chapter 3, “Ghosts in the Machine,” we shall see how a twentieth-century update of the
eleventh-century British Domesday Book was useless by the time it was only a sixtieth the age of the original.
Or consider search, the subject of Chapter 4, “Needles in the Haystack.” At first, search engines such as Google and Yahoo! were interesting conven- iences, which a few people used for special purposes. The growth of the World Wide Web has put so much information online that search engines are for many people the first place to look for something, before they look in books or ask friends. In the process, appearing prominently in search results has become a matter of life or death for businesses. We may move on to purchase from a competitor if we can’t find the site we wanted in the first page or two of results. We may assume something didn’t happen if we can’t find it quickly in an online news source. If it can’t be found—and found quickly—it’s just as though it doesn’t exist at all.


Try these scratch cards to do the disapearing act.

Koan 2: Perfection Is Normal
To err is human. When books were laboriously transcribed by hand, in ancient scriptoria and medieval monasteries, errors crept in with every copy. Computers and networks work differently. Every copy is per- fect. If you email a photograph to a friend, the friend won’t receive a fuzzier version than the original. The copy will be identical, down to the level of details too small for the eye to see.
Computers do fail, of course. Networks break down too. If the

power goes out, nothing works at all. So the statement that copies are nor- mally perfect is only relatively true. Digital copies are perfect only to the extent that they can be communicated at all. And yes, it is possible in theory that a single bit of a big message will arrive incorrectly. But networks don’t just pass bits from one place to another. They check to see if the bits seem to have been damaged in transit, and correct them or retransmit them if they seem incorrect. As a result of these error detection and correction mecha- nisms, the odds of an actual error—a character being wrong in an email, for example—are so low that we would be wiser to worry instead about a meteor hitting our computer, improbable though precision meteor strikes may be.
The phenomenon of perfect copies has drastically changed the law, a story told in Chapter 6, “Balance Toppled.” In the days when music was distributed on audio tape, teenagers were not prosecuted for making copies of songs, because the copies weren’t as good as the originals, and copies of copies would be even worse. The reason that thousands of people are today receiv- ing threats from the music and movie industries is that their copies are per- fect—not just as good as the original, but identical to the original, so that even the notion of “original” is meaningless. The dislocations caused by file sharing are not over yet. The buzzword of the day is “intellectual property.” But bits are an odd kind of property. Once I release them, everybody has them. And if I give you my bits, I don’t have any fewer.

Koan 1: 
It’s All Just Bits Your computer successfully creates the illusion that it contains photographs, letters, songs, and movies. All it really contains is bits, lots of them, patterned in ways you can’t see. Your computer was designed to store just bits—all the files and folders and different kinds of data are illusions created by computer programmers. When you send an email containing a photograph, the computers that handle your message as it flows through the Internet have no idea that what they are handling is part text and part graphic. Telephone calls are also just bits, and that has helped create competition—traditional phone companies, cell phone companies, cable TV companies, and Voice over IP (VoIP) service providers can just shuffle bits around to each other to complete calls. The Internet was designed to handle just bits, not emails or attachments, which are inventions of software engineers. We couldn’t live without those more intuitive concepts, but they are artifices.   There is no difference between a text, picture, song or phone call to the computer.  Underneath, it’s all just bits.
