3. The Blog of the Week: “The possibilities of exploring the Internet in our life time let alone in one course is probably impossible. The Internet effects our lives in all different ways, some good and some bad. I compare the Internet to space; there’s no point asking about the how comes or what ifs. I don’t think the Internet will ever be regulated to protect the innocent. Its too invisible and the possibilities are endless. The evolution of the Internet is a phenomenon in itself. I feel that the better technology gets the worse we are. It almost seems that humans are becoming extinct and machines are the way of the future. Our lifestyles are evolving to be machine dependant. We could never go back to life before the computer or the Net. Laziness is a natural trait and the invention of the Internet was a dream come true.”

4. Judge Roberts Confirmation “Since you've talked about the Internet, let me turn to a disturbing trend in regards to the Internet. And that has, quite frankly, to do with pornography. We have passed several bills in Congress -- Communications Decency Act -- to protect our children. The Supreme Court struck it down. I'm not going to ask you to comment about that. A few years later, we passed the Child Online Protection Act, again, with the intent to protect our children. Again, the court struck it down. Unlike the traditional public square, the Internet has really become a place for the distribution of some, I find, very troubling material, and that is pornography. …. Few of us would march our sons and daughter off to war to preserve the citizens' right to see, quote, 'specified sexual activities,' end of quote, exhibited in the theaters of our choice, end of quote” - Sen. Michael DeWine (R-Ohio)

6. What is the Internet? “The Federal Networking Council (FNC) agrees that the following language reflects our definition of the term "Internet". "Internet" refers to the global information system that -- (i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons;(ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and (iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein."

10. What is ARPA? Created "for the direction or performance of such advanced projects in the field of research and development as the Secretary of Defense shall, from time to time, designate by individual project or by category." Source: http://www.darpa.mil/body/arpa_darpa.html

11. The Visionary of the Internet In August 1962, J.C.R. Licklider, a VP at BBN, describes the idea of a “Galactic Network”. He envisioned a globally interconnected set of computers through which everyone could quickly access data and programs from any site.

12. A Vision of HyperText and HyperLinks • In 1965, Ted Nelson gave a presentation titled "A File Structure for the Complex, the Changing, and the Indeterminate." Nelson described to the scientific community his interconnected "docuverse“, an idea similar to Licklider’s Gallactic Network. • Nelson coined the term "hypertext“ and “hyperlink”

13. What is HyperText? hypertext n. 1. The organization of information units into connected associations that a user can choose to make. An instance of such an association is called a link or hypertext link or a hyperlink. Source: http://www.indrum.com/planet/glossary.htm

14. What is ARPANET? • August 30, 1969 –ARPANET, the first Wide Area Network, is introduced. The first manifestation of ARPANET connected four universities. • Implements TCP/IP and packet switching Source: http://schools.keldysh.ru/sch444/MUSEUM/PICTURE/ARPANET.JPG

15. Networked Email • Ray Tomlinson sent the first network email in 1971 using a program called SNDMSG Source: http://openmap.bbn.com/%7Etomlinso/ray/ka10.html

16. CSNET • 1980, NSF funds the development of a network for universities not doing research for DARPA (previously known as ARPA) • Estimated one day to build • Limited to computer science departments because commercial interests were deemed impractical. • Connected ARPANET and CSNET • 56 Kbps network Dr. Lawrence Landweber

17. USENET • Started in 1979 as a “poor man’s ARPANET” at Duke University. • Postings to USENET are called articles. Postings are categorized into newsgroups.

18. MILNET • Started between 1983 and 1984, it separated the Military part of ARPANET from the academics. • Only carried unclassified information • Still exists today

19. FIDONET FidoNet was invented in 1984 by Tom Jennings to move messages to Bulletin Board Services (BBS). The entire system was done through telephone calls during the National Mail Hour. It was organized entirely by private citizens.

He later renamed the browser Nexus. • Author of the first website: http://nxoc01.cern.ch/hypertext/WWW/TheProject.html • Alternative names he considered naming the Web • Mine of Information (MOI) • The Information Mine (TIM) • Information Mesh

21. The First Popular Browser: Mosaic

22. And along came Netscape . . . • In 1993, Marc Andreessen was making $6.85 an hour working at the University of Illinois at Urbana Champlain. • By the end of 1995, he was worth over $170 million Source: http://www.usatoday.com/tech/news/2003-03-09-internet_x.htm

23. Never to be outdone • In 1975, Bill Gates drops out of Harvard University and starts Microsoft. • Nov. 16, 1995, Goldman, Sachs & Co. removed Microsoft's stock from its “recommended for purchase” list. • Turns Microsoft around and becomes wealthiest man in the world.

24. Open Source Goes Mainstream • Linus Torvalds, a Finnish college student, creates Linux, an open source version of UNIX in 1991. • Soon a worldwide network of programmers began developing features and using Linux. • Linux, a free Operating System, rivals Microsoft in Web Servers. • In June 2002, Steve Balmer of Microsoft states, "Linux is a cancer that attaches itself in an intellectual property sense to everything it touches."

25. The Meow Wars on USENET "I suggest that we start either posting or crossposting to alt.tv.beavis-n-butthead. I also suggest that we use big words and perfect grammar, and refuse to write as the young ruffians in question speak. This could lead to some interesting 'dialogue.' “ -Matt Bruce Source: http://madfishwillies.mu.nu/archives/016097.html

26. Yahoo! “The two founders of Yahoo!, David Filo and Jerry Yang, Ph.D. candidates in Electrical Engineering at Stanford University, started their guide in a campus trailer in February 1994 as a way to keep track of their personal interests on the Internet. Before long they were spending more time on their home-brewed lists of favorite links than on their doctoral dissertations. Eventually, Jerry and David's lists became too long and unwieldy, and they broke them out into categories. When the categories became too full, they developed subcategories ... and the core concept behind Yahoo! was born. The Web site started out as "Jerry and David's Guide to the World Wide Web" but eventually received a new moniker with the help of a dictionary. The name Yahoo! is an acronym for "Yet Another Hierarchical Officious Oracle“ Source: http://docs.yahoo.com/info/misc/history.html
