11.5 Issues and Trends

Rural Areas and Access to Information

One of the founding principles of many public library systems is to allow for free and open access to information. Historically, one of the major roadblocks to achieving this goal has been a simple one: location. Those living in rural areas or those with limited access to transportation simply could not get to a library. But with the spread of the Internet, the hope was that a global library would be created—an essential prospect for rural areas.

One of the most remarkable educational success stories in the Department of Education’s study is that of the Chugach School District in Alaska. In 1994, this district was the lowest performing in the state: over 50 percent staff turnover, the lowest standardized test scores, and only one student in 26 years graduating from college (U.S. Department of Education, 2004). The school board instituted drastic measures, amounting to a complete overhaul of the system. They abolished grade levels, focusing instead on achievement, and by 2001 had increased Internet usage from 5 percent to 93 percent.

The Department of Education study emphasizes these numbers, and with good reason: The standardized test percentile scores rose from the 1920s to the 1970s in a period of 4 years, in both math and language arts. Yet these advances were not exclusive to low-performing rural students. In Florida, the Florida Virtual School system allowed rural school districts to offer advanced-placement coursework. Students excelling in rural areas could now study topics that were previously limited to districts that could fill (and fund) an entire classroom. Just as the Interstate Highway System commercially connected the most remote rural communities to large cities, the Internet has brought rural areas even further into the global world, especially in regard to the sharing of information and knowledge.

The Cloud: Instant Updates, Instant Access

As technology has improved, it has become possible to provide software to users as a service that resides entirely online, rather than on a person’s personal computer. Since people can now be connected to the Internet constantly, they can use online programs to do all of their computing. It is no longer absolutely necessary to have, for example, a program like Microsoft Word to compose documents; this can be done through an online service like Google Docs or Zoho Writer.

“Cloud computing” is the process of outsourcing common computing tasks to a remote server. The actual work is not done by the computer attached to the user’s monitor, but by other (maybe many other) computers in the “cloud.” As a result, the computer itself does not actually need that much processing power; instead of calculating “1 + 1 = 2,” the user’s computer asks the cloud, “What does 1 + 1 equal?” and receives the answer. Meanwhile, the system resources that a computer would normally devote to completing these tasks are freed up to be used for other things. An additional advantage of cloud computing is that data can be stored in the cloud and retrieved from any computer, making a user’s files more conveniently portable and less vulnerable to hardware failures like a hard drive crash. Of course, it can require quite a bit of bandwidth to send these messages back and forth to a remote server in the cloud, and in the absence of a reliable, always-on Internet connection, the usefulness of these services can be somewhat limited.

The concept of the cloud takes into account all the applications that are hosted on external machines and viewed on a user’s computer. Google Docs, which provides word processors, spreadsheets, and other tools, and Microsoft’s Hotmail, which provides e-mail access, both constitute aspects of the “cloud.” These services are becoming even more popular with the onset of mobile applications and netbooks, which are small laptops with relatively little processing power and storage space that rely on cloud computing. A netbook does not need the processing power required to run Microsoft Word; as long as it has a web browser, it can run the Google Docs word processor and leave (almost) all of the processing to the cloud. Because of this evolution of the Internet, computers can be built less like stand-alone machines and more like interfaces for interacting with the larger system in the cloud.

One result of cloud computing has been the rise in web applications for mobile devices, such as the iPhone, BlackBerry, and devices that use Google’s Android operating system. 3G networks, which are cell phone networks capable of high-speed data transfer, can augment the computing power of phones just by giving the phones the ability to send data somewhere else to be processed. For example, a Google Maps application does not actually calculate the shortest route between two places (taking into account how highways are quicker than side roads, and numerous other computational difficulties) but rather just asks Google to do the calculation and send over the result. 3G networks have made this possible in large part because the speed of data transfer has now surpassed the speed of cell phones’ calculation abilities. As cellular transmission technology continues to improve with the rollout of the next-generation 4G networks (the successors to 3G networks), connectivity speeds will further increase and allow for a focus on ever-more-comprehensive provisions for multimedia.

Just Trust Me: Bias on the web

One noticeable thing on Paul Krugman’s site is that all of his book reviews are positive. Although these are probably real reviews, they may not be representative of his critical reception at large. Mainstream journalistic sources usually attempt to achieve some sort of balance in their reporting; given reasonable access, they will interview opposing viewpoints and reserve judgment for the editorial page. Corporate sources, like on Krugman’s site, will instead tilt the information toward their product.

Often, the web is viewed as a source of entertainment, even in its informational capacity. Because of this, sites that rely on advertising may choose to publish something more inflammatory that will be linked to and forwarded more for its entertainment value than for its informational qualities.

On the other hand, a website might attempt to present itself as a credible source of information about a particular product or topic, with the end goal of selling something. A website that gives advice on how to protect against bedbugs that includes a direct link to its product may not be the best source of information on the topic. While so much on the web is free, it is worthwhile looking into how websites actually maintain their services. If a website is giving something away for free, the information might be biased, because it must be getting its money from somewhere. The online archive of Consumer Reports requires a subscription to access it. Ostensibly, this subscription revenue allows the service to exist as an impartial judge, serving the users rather than the advertisers.

Occasionally, corporations may set up “credible” fronts to disseminate information. Because sources may look reliable, it is always important to investigate further. Global warming is a contentious topic, and websites about the issue often represent the bias of their owners. For example, the Cato Institute publishes anti-global-warming theory columns in many newspapers, including well-respected ones such as the Washington Times. Patrick Basham, an adjunct scholar at the Cato Institute, published the article “Live Earth’s Inconvenient Truths” in the Washington Times on July 11, 2007. Basham writes, “Using normal scientific standards, there is no proof we are causing the Earth to warm, let alone that such warming will cause an environmental catastrophe (Basham, 2007).”

However, the website ExxposeExxon.com states that the Cato Institute received $125,000 from the oil giant ExxonMobil, possibly tainting its data with bias (Exxon, 2006). In addition, ExxposeExxon.com is run as a side project of the international environmental nonprofit Greenpeace, which may have its own reasons for producing this particular report. The document available on Greenpeace’s site (a scanned version of Exxon’s printout) states that in 2006, the corporation gave $20,000 to the Cato Institute (Greenpeace, 2007) (the other $105,000 was given over the previous decade).

This back-and-forth highlights the difficulty of finding credible information online, especially when money is at stake. In addition, it shows how conflicting sources may go to great lengths—sorting through a company’s corporate financial reports—in order to expose what they see as falsehoods. What is the upside to all of this required fact-checking and cross-examination? Before the Internet, this probably would have required multiple telephone calls and plenty of time waiting on hold. While the Internet has made false information more widely available, it has also made checking that information incredibly easy.

Hacking E-mail: From LOVE-LETTER-FOR-YOU to Google in China

Another explosive scandal involving e-mail account hacking also occurred in late 2009, when Google’s Gmail service was hacked by IP addresses originating in China. Gmail was one of the primary services used by human rights activists due to its location in the United States and its extra encryption. To understand the magnitude of this, it is important to understand the history of e-mail hacking and the importance of physical server location and local laws.

In 2000, a computer virus was unleashed by a student in the Philippines that simply sent a message with the subject line “I Love You.” The e-mail had a file attached, called LOVE-LETTER-FOR-YOU.TXT.vbs. The suffix “.txt” is generally used for text files and was meant, in this case, as a distraction; the file’s real suffix was “.vbs,” which means that the file is a script. When run, this script ran and e-mailed itself across the user’s entire address book, before sending any available passwords to an e-mail address in the Philippines. One of the key aspects of this case, however, was a matter of simple jurisdiction: The student was not prosecuted, due to the lack of computer crime laws in the Philippines (Zetter, 1983).

The encryption that Gmail uses resulted in only two of the accounts being successfully hacked, and hackers were only able to see e-mail subject lines and timestamps—no message content was available (Zetter, 2010). Since the chaos that ensued after the “I Love You” virus, e-mail users and service providers have become more vigilant in their defensive techniques. However, the increased reliance on e-mail for daily communication makes it an attractive target for hackers. The development of cloud computing will likely lead to entirely new problems with Internet security; just as a highway brings two communities together, it can also cause these communities to share problems.

Can’t Wait: Denial of Service

Although many people increasingly rely on the Internet for communication and access to information, this reliance has come with a hefty price. Most critically, a simple exploit can cause massive roadblocks to Internet traffic, leading to disruptions in commerce, communication, and, as the military continues to rely on the Internet, national security.

Distributed denial-of-service (DDoS) attacks work like cloud computing, but in reverse. Instead of a single computer going out to retrieve data from many different sources, DDoS is a coordinated effort by many different computers to bring down (or overwhelm) a specific website. Essentially, any web server can only handle a certain amount of information at once. While the largest and most stable web servers can talk to a huge number of computers simultaneously, even these can be overwhelmed.

During a DDoS attack on government servers belonging to both the United States and South Korea in July 2009, many U.S. government sites were rendered unavailable to users in Asia for a short time (Gorman & Ramstad, 2009). Although this did not have a major effect on U.S. cyber-security, the ease with which these servers could be exploited was troubling. In this case, the DDoS attacks were perpetuated by an e-mail virus known as MyDoom, which essentially turned users’ computers into server-attacking “zombies.” This exploit—coupling an e-mail scam with a larger attack—is difficult to trace, partly because the culprit is likely not one of the original attackers, but rather the victim of a virus used to turn vulnerable computers into an automated hacker army. Since the attack, President Barack Obama has committed to creating a new post for a head of cyber-security in the government.

Net Neutrality Legislation: The FCC and AT&T

One of the key roadblocks to Internet legislation is the difficulty of describing the Internet and the Internet’s place among communication bills of the past. First of all, it is important to realize that legislation relating to the impartiality of service providers is not unheard-of. Before the 1960s, AT&T was allowed to restrict its customers to using only its own telephones on its networks. In the 1960s, the FCC launched a series of “Computer Inquiries,” stating, in effect, that any customer could use any device on the network, as long as it did not actually harm the network. This led to inventions such as the fax machine, which would not have been possible under AT&T’s previous agreement.

A key point today is that these proto–net neutrality rules protected innovation even when they “threatened to be a substitute for regulated services (Cannon, 2003).” This is directly relevant to a controversy involving Apple’s iPhone that culminated in October 2009 when AT&T agreed to allow VoIP (voice over Internet protocol) on its 3G data networks. VoIP services, like the program Skype, allow a user to place a telephone call from an Internet data line to a traditional telephone line. In the case of the iPhone, AT&T did not actually block the transmission of data—it just had Apple block the app from its App Store. Since AT&T runs the phone service as well as the data lines, and since many users have plans with unlimited data connections, AT&T could see its phone profits cut drastically if all its users suddenly switched to using Skype to place all their telephone calls.

Misleading Metaphors: It’s Not a Big Truck

Senator Ted Stevens, the former head of the committee in charge of regulating the Internet, said on the floor of the Senate that the Internet is “not a big truck…it’s a series of tubes (Curtis, 2006).” According to this metaphor, an e-mail can get “stuck in the tubes” for days behind someone else’s material, leading to poorer service for the customer. In reality, service providers sell data-usage plans that only set a cap on the amount of data that someone can send over the Internet (measured in bits per second, where a bit is the smallest measurement of data). If a service is rated at 1.5 million bits per second (megabits per second, or 1.5 Mbps), it may only reach this once in a while—no one can “clog the tubes” without paying massive amounts of money for the service. Theoretically, the company will then invest this service fee in building more robust “tubes.”

Net neutrality is difficult to legislate in part because it can be confusing: It relies on understanding how the Internet works and how communications are regulated. Stevens’s metaphor is misleading because it assumes that Internet capacity is not already regulated in some natural way. To use the superhighway analogy, Stevens is suggesting that the highways are congested, and his solution is to allow companies to dedicate express lanes for high-paying customers (it should be noted that the revenue would go to the service providers, even though the government has chipped in quite a bit for information superhighway construction). The danger of this is that it would be very difficult for a small business or personal site to afford express-lane access. Worse yet, the pro–net neutrality organization Save the Internet says that a lack of legislation would allow companies to “discriminate in favor of their own search engines” and “leave the rest of us on a winding dirt road (Save the Internet, 2010).” For areas that only have access to one Internet service, this would amount to a lack of access to all the available content.
