"Hugo Cornwall "The Hacker's handbook"" - читать интересную книгу автора None of this is easy and will probably involve breaches of several
laws, including theft of copyright material! However a number of news agencies also transmit services by radio, in which case the signals can be hijacked with a short-wave receiver. Chapter 9 explains. Historic news, as opposed to the current stuff from agencies, is now becoming available on-line. The New York Times, for example, has long held its stories in an electronic 'morgue' or clippings library. Initially this was for internal use, but for the last several years it has been sold to outsiders, chiefly broadcasting stations and large corporations. You can search for information by a combination of keyword and date-range. The New York Times Information Bank is available through several on-line hosts. As the world's great newspapers increasingly move to electronic means of production--journalists working at VDUs, sub-editors assembling pages and direct-input into photo-typesetters--the additional cost to each newspaper of creating its own morgue is relatively slight and we can expect to see many more commercial services. In the meantime, other publishing organisations have sought to make available articles, extract or complete, from leading magazines also. Two UK examples are Finsbury Data Services' Textline and Datasolve's d Reporter, the latter including material from the BBC's monitoring service, Associated Press, the Economist and the Guardian. Textline is an abstract service, but World Reporter gives the full text. In October 1984 it already held 500 million English words. held 16 million full text articles at that same date. All these services are expensive for casual use and are accessed by dial-up using ordinary asynchronous protocols. Many electronic newsrooms also have dial-in ports for reporters out on the job; depending on the system these ports not only allow the reporter to transmit his or her story from a portable computer, but may also (like Basys Newsfury used by Channel Four News) let them see news agency tapes, read headlines and send electronic mail. Such systems have been the subject of considerable hacker speculation. Financial Services The financial world can afford more computer aids than any other non-governmental sector. The vast potential profits that can be made by trading huge blocks of currency, securities or commodities--and the extraordinary advantages that a slight 'edge' in information can bring--have meant that the City, Wall Street and the equivalents in Hong Kong, Japan and major European capitals have been in the forefront of getting the most from high-speed comms. Ten years ago the sole form of instant financial information was the ticker tape--telegraphy technology delivering the latest share price movements in a highly abbreviated form. As with its news equivalents, these were broadcast services (and still are, for the services still exist) sent along leased telegraph lines. The user |
