Developer s challenge Why would you want to clarify your own vision rather than assisting others in nding theirs Developer s follow-on response If the Two cannot think of an answer or gives an unconvincing answer, say: It doesn t sound like you really want to do something for yourself, then wait for the response. If the Two gives a convincing response, say: It sounds as though this is really important to you. Please tell me more about this and what you would gain from giving more attention to your own needs and desires.

The boolean-expression must produce a bool result. (This expression is also called a predicate.) There can be more than one where clause in a query. In the program, this where clause is used:

Layer 3: IP switching. With the most intense battle for ATM acceptance being in the LAN and corporate backbone, some new technological developments have started to appear; they aim to make use of the speed of ATM, without the complexity of ATM protocols (such as signaling, LANE and MPOA), and therefore gain acceptance as a viable alternative to ATM. Foremost among these developments is IP switching (from Ipsilon), where ATM switches classify flows of IP data transfer as either long or short. Short flows, such as those from SNMP and other IP protocols, are routed as normal by each IP switch. Long flows, such as those from FTP, are allocated direct ATM connections and are switched at ATM speeds through the network of IP switches (Figure 11.14). Other rival techniques also have been announced, such as Tag switching (from Cisco). While these new technologies do appear to offer advantages over ATM technology, particularly in today s IP networks, they currently do not address the need for QoS capabilities. As users start to demand real-time service guarantees over the

In January 1996, companies began to announce their DVD plans for the coming year. The road ahead looked smooth and clear until the engineers in their rose-colored glasses, riding forecast-fueled marketing machines, crashed headlong into the protectionist paranoia of Hollywood. As the prospect of DVD solidified, the movie studios began to obsess about what would happen when they released their family jewels in pristine digital format with the possibility that people could make high-quality videotape copies or even perfect digital dubs. Rumors began to surface that DVD would be delayed because of copyright worries. On March 29, the Consumer Electronics Manufacturers Association (CEMA) and the Motion Picture Association of America (MPAA) announced that they had agreed to seek legislation that would protect intellectual property and consumers rights concerning digital video recorders. They hoped their proposal would be included in the Digital Recording Act of 1996 that was about to be introduced in the US Congress. Their recommendations were intended to j allow consumers to make home video recordings from broadcast or basic cable television, j allow analog or digital copies of subscription programming, with the qualification that digital copies of the copy could be prevented, and j allow copyright owners to prohibit copying from pay-per-view, video-ondemand, and prerecorded material. The two groups hailed their agreement as a landmark compromise between industries that often had been at odds over copyright issues. They added that they welcomed input from the computer industry, and input they got! A week later, an agitated group of 30 computer and communications companies fired off a list of critiques of the technical specifications that had been proposed by Hollywood and the consumer electronics companies. They were less than thrilled that MPAA and CEMA had attempted to unilaterally dictate hardware and software systems that would keep movies from being copied onto personal computers. The computer industry said it preferred voluntary standards for content protection and objected to being told exactly how to implement things. Hollywood countered that the computer industry had been invited to participate early on but did not, either due to laziness or arrogance. The news media was filled with reports of DVD being stalled, embattled, and derailed. In anticipation of the imminent release of DVD, and with content protection details still unresolved, the MPAA and CEMA announced draft legislation called the Video Home Recording Act (VHRA), designed to legally uphold content protection, which included the insertion of a 2-bit identifier in the video stream to mark content as copy-prohibited. The two groups had been working on the legislation since 1994, apparently without directly consulting the computer industry, which filed a letter of protest against the proposed legislation, requesting that an encryption and watermarking scheme be used as a technical alternative to legislation. The content protection technology eventually became the much more complex CSS, and the legislation mutated into the Digital Millennium Copyright Act (DMCA). On June 25, Toshiba announced that the 10 companies in the consortium had agreed to
