Developing an Intranet for a Small Unit Capt Internet and Intranet Developing an Intranet for a Small Unit Capt. Dan Stormont U.S. Air Force The Theater Air Command and Control Simulation Facility (TACCSF) is a fairly small unit that works closely with contractors to develop simulation software and scenarios. The small size of the unit and the inter- action with contractors prompted us to develop efficient ways to share data and documentation. This article discusses the approaches the TACCSF has taken to set up an Intranet using limited resources. It addresses the use of shared memory devices and the problems associated with that approach as well as the efforts undertaken to develop a browser-based (Intranet) paradigm. The lessons learned from these attempts are presented, as are our current efforts and future plans to develop the most cost-effective solution that will satisfy our needs.

The law has allowed websites to host content created by users without, as the bill’s author, Rep. Chris Cox (R-CA), warned in 1995, “spending vast sums of money trying to define elusive terms that are going to lead to a flood of legal challenges.” Without the broad protections of 230(c)(1) in particular, websites would face “death by ten thousand duck-bites” in the form of massive litigation risks. NTIA asks the FCC to turn this law on its head, but the FCC has no authority to reinterpret the statute. The plain language and the legislative history of Section 230 demonstrate that Congress did not intend to grant any regulatory authority to the FCC. Instead, as Rep. Cox declared, Congress did “not wish to have a Federal Computer Commission with an army of bureaucrats regulating the Internet.” Under the statute’s express terms, the “interactive computer service” providers protected by Section 230 are not “information service providers,” nor are they otherwise subject to the FCC’s jurisdiction.

  • World Wide Web Distributed Authoring and Versioning (WEBDAV): an Introduction1
    World Wide Web Distributed Authoring and Versioning (WEBDAV): An Introduction1 E. James Whitehead, Jr. Dept. of Information and Computer Science University of California, Irvine Irvine, CA 92697-3425 Email: [email protected] Phone: (714) 824-4121 Fax: (714) 824-1715 1.0 Introduction Today the typical use of the World Wide Web is to browse information in a largely read- only manner. However, this was not the original conception of the Web; as early as 1990, a prototype Web editor and browser was operational on the Next platform, demonstrating how Web content could be read and written. Unfortunately, most of the world never saw this editor/browser, instead developing their view of the Web from the widely distributed text-based line mode browser. When NCSA Mosaic was developed, it improved the line mode browser by adding a graphical user interface and inline images, but had no provision for editing. As Mosaic 2.4 reached critical mass in 1993-4, “publish/browse” became the dominant model for the Web. However, the original view of the Web as a readable and writable collaborative medium was not lost. In 1995 two browser/editor products were released: NaviPress by NaviSoft and FrontPage by Vermeer. These products began developing a market for authoring tools which allow a user to edit HyperText Markup Language (HTML) [Ragg97] pages remotely, taking advantage of the ability to work at a distance over the Internet. In early 1996, NaviSoft and Vermeer were purchased by America Online and Microsoft respec- tively, presaging major corporate interest in Web distributed authoring technology.

  • Remember, the Dial-Up Era of Internet Access? Back Then There Were Line
    Remember, the dial-up era of Internet access? Back then there were line sharing mandates requiring the telephone company to allow firms like AOL, Prodigy, CompuServe etc to use the phone company’s network to supply dial-up Internet access into an individual’s home. You could use your home phone connection - suppose you had AT&T for your home telephone service and AOL in that case AOL could use your phone connection with AT&T or whatever phone company you had for an affordable cheap reasonable rate to connect you to their internet service. AOL could use AT&T’s phone network to connect an AT&T phone customer to the Internet. There were plenty of competitors in the dial-up arena from AOL and Prodigy to CompuServe, NetZero and even EarthLink to name a few of the commercial providers, What happened in the broadband era? When we started the broadband era in 2001 the U.S. was poised to lead the world in broadband and have the same level of competition as the dial-up market but the FCC under George W. Bush’s Presidency ended the line sharing requirement and any competition mandates by re-classifying broadband services under Title I of the Telecommunications Act as an information service. We need to get back to that. We need competition restored it is the best way after all to protect Net Neutrality. If competition mandates had been continued and phone companies had to provide access to their infrastructure to competitors today we would still have plenty of land-line or wire-line competition for the Internet.

Gravity and mass It is said to have been the sight of an apple falling from a tree that, around 1665, gave Isaac Newton the idea that the force that pulls an apple to earth is the same as that which keeps the moon in its orbit around the earth. The reason the moon does not fall to earth is because of the counteracting effect of its orbital motion. If the moon were to cease its orbital motion and fall to earth, the acceleration due to gravity that it would experience at the earth’s surface would be 9.8 m/s² – the same as that experienced by an apple or any other object in free fall. Newton’s universal law of gravitation states that the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. To calculate the gravitational force (F), their masses (m 1 and m 2) and the gravitational constant (G) are multiplied together, and the result is divided by the square of the distance (r) between them: F = http://ourworld.compuserve.com/homepages/dp5/gravity.htm 15.12.2006 Gravity and antigravity (1) Page 2 of 29 Gm 1m2/r². According to newtonian theory, the gravitational force between two or more bodies is therefore dependent on their masses.
