Outline for February 10, 1998:
History of Community Networking
7:00 Class
catch up from last week
amateur Bulletin Board Systems (BBSes)
- hosted by computer hobbyists, starting in 1978
- all costs absorbed by "sysop" (system operator)
- smaller BBSes had only one modem and phone line connected, so
chatting was impossible with anyone but the sysop
- services offered in addition to CMC included software archives and
multiplayer role-playing games
- each BBS in a town had its own unique flavor and community spirit (even though the same bunch of people might use them all) until Fidonet homogenized conferences into newsgroups (in my experience)
early community networks
- Community Memory, Berkeley, CA founded in early 1970s with
public terminals only: pay to post. All material local, contributed
anonymously by users. System phased out several years later when demand
declined.
- Old Colorado City, first community-oriented BBS, founded 1980
- St. Silicon's Hospital and Information Dispensary, Cleveland,
OH founded 1984 to distribute medical information through public Q&A
with doctors; later became Cleveland Free-Net
- The WELL, San Francisco, CA, founded 1985, first
community-oriented commercial online service
Cleveland Free-Net (CFN)
- founded in 1986 from St. Silicon's Hospital, which was an Apple ][
with a single modem, sponsored by Case Western Reserve University
- CWRU wrote a new software package (FreePort) to run CFN on UNIX
workstations, and later sold this software to other CNs.
- 12 years later, CWRU still operates CFN, which has become the
largest CN in the world.
Big Sky Telegraph
- in 1988, BST was the first organization to try the
networking-communities approach to CNs
- connected 40 rural schools and 12 rural libraries in Montana to each
other and later the Internet.
the National Public Telecomputing Network (NPTN)
- CFN's founder left CWRU to found NPTN in 1989
- NPTN's goal: help other cities start and maintain Free-Nets based on
CFN's model
- "the Blue Book" gave instructions on how to start a Free-Net
from the grassroots level
- NPTN served as a central, legitimate agency to channel major
grants to local communities, sometimes even buying the hardware and
software and delivering the Free-Net pre-configured to its destination
- "cybercast" content included electronic mailing lists on
Free-Net administration, teledemocracy, White House press releases, the
TeleOlympics (in which athletes compare achievements via computer), and
the Collaboratory (where students work together on science projects over
the Internet)
the WWW boom and civic networking
- The World Wide Web was created in 1992, but it didn't catch on until
the first graphical browser, Mosaic, was released in 1993
- "civic networks" are community Web sites, generally sponsored by
local government, allowing small businesses and nonprofit organizations to
publicize themselves very inexpensively
- analogy: if the Internet is like the Interstate Highway System,
most Web sites are like truck stops or billboards, but civic networks
attempt to be towns
- some civic networks have CMC features like those of community
networks
wired communities
- Blacksburg Electronic Village
founded 1993 as a dial-up CN with some public terminals
- Virginia Tech and the phone company helped bring ethernet networking
into apartments, businesses, and homes, putting off-campus computers as
directly on the Internet as those on campus
- chain reaction: BEV's networking encourages more and more
people to buy computers, which increases demand for more networking
- less ambitious projects include Playing to Win and Plugged In, which
wire community centers in disadvantaged areas into the Internet and
provide classes and activities to the community
money from heaven
- National Telecommunications and Information Agency (NTIA) announces
its Telecommunication and Information Infrastructure Assistance Program
(TIIAP) grants, 1994, funding many rural communities which had previously
not been able to afford CNs
- the California Department of Transportation creates the SmartCommunities project, 1995,
to wire California suburbs in order to allow more telecommuting (and
therefore less automobile traffic), using Davis Community Network and the
City of Chula Vista as test sites
NPTN collapses, November 1996
Association for Community Networking (AFCN) founded, October 1997
- AFCN includes many of the biggest movers & shakers in the CN
movement in its board of directors, ensuring that it will become the US
authority on CNs
- AFCN was originally intended to be a worldwide organization, but
Telecommunities Canada convinced it to limit its influence to the US
Do CNs work? What do they do well? What don't they do well?
- Clearly CNs are serving some members of the population, but are they
the targeted members? Do they represent the community? Few CNs collect
the demographic statistics necessary to answer these questions.
- CN users say they feel a sense of community, but is it the same
community that exists outside the CN? Sometimes yes, sometimes no.
- CMC will never replace some other forms of communication, but it can
help encourage communication where there was little before
- very few CNs have studied themselves sufficiently to prove that they
do what they say they do
CN Rule #2: Plan for evaluation!
Optional Workshop: operating systems and the Internet
- An OS is the software that lets people and programs interact with the
computer. Different OSes have almost identical functionality but
represent different priorities for interactivity, number of users, and
ease of use.
- Early OSes (c. 1940): one input (punched cards), one output
(teletype), one task at a time.
- The Mainframe Mentality (c. 1960): many users, each with own
input and output (terminal), many tasks simultaneously, high
interactivity. Minicomputers such as the VAX are examples of this
paradigm.
- UNIX (c. 1970): mainframe functionality, but "scalable" --
UNIX can be run on a supercomputer (intended for big tasks, low
interactivity), mainframe, or "workstation" (a souped-up PC allowing
remote login; like the ones in MathLAN). UNIX does not belong to any one
company.
- Personal Computers (c. 1970): one user, one input & output, but
intended for casual home or office use -- easy to learn. Primary PC OSes
(Windows and Mac OS) are becoming more and more similar to UNIX, due
mainly to the popularity of the Internet. On the other hand, the
popularity of Mac OS inspired Xwindows, a graphical interface for UNIX.
PCs can be made to support multiple users, but they require additional
software (hence the BBS software that became available in the 1980s).
- Network Computers (c. 1997): like very smart mainframe
terminals, able to use any server on the network (including the Internet).
Emphasis on interchangeability: sit down at any NC and stick in your
smartcard and password to access your files over the network. Built
entirely on "open" standards which belong to no one, so costs are very
low. However, functionality is also low.
- The Internet is a worldwide network of local networks
- Computer networks work because of "protocols" -- sets of rules
for who talks when, and what they can say.
- Local Area Networks (LANs) are like shouting in a crowded room:
everybody hears what everybody says, but they choose to ignore private
conversations.
- The Internet routes messages from one LAN to another, so it's more
like the U.S. Postal Service than a crowded room.
- The Internet is the only network that actually looks like a net;
many connections are redundant because it was designed to survive a
nuclear war.
- Protocols are independent of the medium, so Internet signals can
travel via satellite, fiberoptics, special high-speed copper wires, or
ordinary phone lines. Fiberoptics allow the fastest transfer of
information, phone lines the slowest.
- Computers that dial into Internet Service Providers (ISPs) with
modems are not actually "on the Internet," nor are they on a LAN. Signals
are routed by the ISP so that only those pertaining to a specific computer
are sent to that computer.
- Computers which are permanently on the Internet must have "IP"
(Internet Protocol) addresses which may have names associated with them;
for example, ac.grin.edu is 132.161.10.8. Computers that dial into ISPs
usually have only temporary IP numbers and no names.
