- MAP18: GOPHER (PART 1)
- ----------------------
-
- "I have found that a great part of the information I have was
- acquired by looking for something and finding something else
- on the way." -- Franklin P. Adams
-
-
- When I was in elementary school, I was a rather "spirited" child.
- I remember constantly asking my teachers why I had to learn long
- division when I could just as easily use a calculator to come up
- with the answer.
-
- Needless to say, may parents heard from my teachers ... often.
-
- What does this story have to do with this lesson? Well, I am
- proud to announce that we have just finished learning the "long
- division" of the Internet (FTP).
-
- This week we are going to start using the "calculator" of the
- Internet -- a client/server package called "Gopher". (If you have
- Level One connectivity, I will show you on Friday how to access
- Gopher using nothing but E-mail!!)
-
- Gopher was developed at the University of Minnesota, and it is
- a menu-driven application that allows you to hop around the globe
- looking for information. Gopher's interconnected menus allow you
- to "burrow" deeper and deeper until you find the information that
- you are looking for.
-
- Imagine that I decide to gather together all of the information
- that I can find about power line-chomping squirrels, and I put
- that information into a menu-driven library. Also imagine
- that someone else who is interested in the uses of yak fur
- creates a menu-driven yak fur library.
-
- If these two menu-driven libraries are interconnected, anyone who
- has access to my squirrel library will also have access to the
- yak fur library (and vice versa).
-
- Now imagine if THOUSANDS of these specialized libraries were
- interconnected. That is what Gopher does, and all of these
- interconnected Gopher libraries make up what is called
- "Gopherspace."
-
- Think of Gopherspace as being a huge stadium filled with information
- on a myriad of different topics. If you have ever been to a major
- sporting event, you will remember that your ticket to that event
- told you which gate you had to pass through to enter the stadium.
-
- Once you entered the stadium, however, you were free to roam around,
- buy a hot dog, and make fun of the opponent's fans. You had access to
- EVERYTHING in that stadium, regardless of which gate you entered
- through.
-
- Gopherspace is set up the same way. Your "gate" is the client that
- you use to enter Gopherspace. Once are in, however, you are free
- to roam around and take advantage of everything that is inside the
- "stadium".
-
- Why is Gopher so special? Well, unlike Archie which just tells
- you where the information that you want can be found, Gopher actually
- goes out, GETS the information that you want, and puts the information
- on your computer screen! (You could even say that Gopher actually
- "goes fer" the information that you want).
-
- A TOUR OF GOPHERSPACE
-
- I'll explain Gopher access and Gopher commands tomorrow. Today, I
- want to take you on a little tour of "Gopherspace."
-
- We are going to start our tour at GOPHER.SQUIRREL.COM -- a gopher
- site that I have totally made up for this tour. Remember, it
- does not matter where you start -- as long as you are in
- Gopherspace, you have access to the same information that everyone
- else has.
-
- When you access your Gopher client, you will start out in your
- client's "root menu". Each root menu is different, but they all
- have the same basic stuff.
-
- I am going to be using a UNIX Gopher client for today's tour.
- As I said earlier, we'll talk a little more about the commands
- tomorrow, but for now I want you to remember two things:
-
- 1. Your site's root menu will be different from my example.
-
- 2. In a UNIX Gopher client menu, the symbols at the end of
- each menu item tell you what that menu item is. The
- following guide will help you decipher the symbols:
-
-
- / gateways to other menu options
-
- . text, graphic, or program files
-
- <?> requests you can make to a database
- for information
-
- <CSO> phonebook requests you can make to
- a database for information
-
- Also, in a UNIX Gopher client the --> selects which menu item you want
- to enter. You move the --> up and down by using the up and down arrows,
- and you select the menu item by using the enter key.
-
- With that said, let's begin the tour! Our tour starts on the
- GOPHER.SQUIRREL.COM root menu:
-
-
- Root gopher server: gopher.squirrel.com
-
- --> 1. Information about the Squirrel Gopher Server.
- 2. What's new in the Squirrel Gopher.
- 3. Network Resources, Services and Information/
- 4. Squirrel Staff Directory <CSO>
- 5. Squirrel Human Resources Information/
- 6. Potpourri, Miscellaneous Topics/
- 7. Local Squirrel Archives/
- 8. Other Gopher and Information Servers around the World/
-
-
- I move the --> up and down by using the up and down arrows. When I
- finally find a menu item that I want to select, I put the -->
- next to that menu item and press the enter key.
-
- Since the first menu item -- "Information about the Squirrel Gopher
- Server" -- is a file (it has a "." at the end of it), let's see if
- we can get into it!
-
- I move the cursor up to "Information about the Squirrel Gopher
- Server," press enter, and the following appears on my screen:
-
-
- WELCOME TO THE SQUIRREL.COM GOPHER SERVER
-
- The SQUIRREL.COM gopher was created by Patrick "P-Crispy-One" Crispen
- to serve as a repository for more information about squirrels than
- anyone could ever possibly want to know.
-
- While you are here, please check out our special Sally Struthers
- menu which contains ...
-
-
- COOL! Unlike ftp, Gopher allows us to read files before we GET
- them! That's going to save us a whole bunch of time! :)
-
- Let's go back to the root menu and start a REAL journey.
- I'm going to take you to a site we visited just the other day --
- SURAnet!
-
- So I go back to the root menu:
-
-
- Root gopher server: gopher.squirrel.com
-
- 1. Information about the Squirrel Gopher Server.
- 2. What's new in the Squirrel Gopher.
- 3. Network Resources, Services and Information/
- 4. Squirrel Staff Directory <?>
- 5. Squirrel Human Resources Information/
- 6. Potpourri, Miscellaneous Topics/
- 7. Local Squirrel Archives/
- --> 8. Other Gopher and Information Servers around the World/
-
-
- I want to visit other Gopher sites around the world, so I use
- the down arrow to move the cursor down to "Other Gopher and
- Information Servers around the World", press enter, and watch as
- the following appears on my screen:
-
-
- Other Gopher and Information Servers around the World
-
- 1. All the Gopher Servers in the World/
- 2. Search All the Gopher Servers in the World <?>
- 3. Search titles in Gopherspace using veronica/
- 4. Africa/
- 5. Asia/
- 6. Europe/
- 7. International Organizations/
- 8. Middle East/
- --> 9. North America/
- 10. Pacific/
- 11. Russia/
- 12. South America/
- ... snip snip snip (these are my Internet scissors) ...
-
- WOW! This is COOL!
-
- This menu allows me to access Gophers all over the world! I'm going
- to have to remember this.
-
- Let's keep today's tour close to (my) home. I move the cursor down to
- "North America", hit enter, and the following appears on my screen:
-
-
- North America
-
- 1. Canada/
- 2. Costa Rica/
- 3. Mexico/
- --> 4. USA/
-
-
- Well, that certainly narrowed things down a little :)
-
- Let's keep going. I move the cursor down to the "USA" menu, press enter,
- and a new menu appears on my screen:
-
-
- USA
-
- --> 1. All/
- 2. General/
- 3. Alabama/
- 4. Alaska/
- 5. Arizona
- ... snip snip snip ...
- 51. West Virginia/
- 52. Wisconsin/
- 53. Wyoming/
-
-
- Uhh ... 53 entries? Yep -- one for each of the 50 states, one for
- Washington, D.C., one for "All", and one for "General".
-
- I feel like an adventure. I move the cursor up to the "All" menu, press
- enter, prop my feet up, and wait for the following new menu to appear
- on my screen:
-
-
- All
-
- 1. 1994 California Voter information/
- 2. AACRAO National Office, Washington, DC/
- 3. AATF - American Association of Teachers of French/
- 4. ACADEME THIS WEEK (Chronicle of Higher Education)/
- ... snip snip snip ...
- 988. SUNY Office of Library Services
- --> 989. SURAnet NIC/
- 990. Safety Information Resources on the InterNet/
- 991. Sailor - Maryland's Information Network/
- ... snip snip snip ...
-
- WHOA! SURAnet!!! We've been there!
-
- Let's drop in and see if they missed me. I move the cursor to "SURAnet",
- press enter, and the following menu appears on my screen:
-
-
- SURAnet NIC
-
- 1. About this Gopher.
- 2. Databases and Network Information/
- --> 3. FTP gateway link to ftp.sura.net/
- 4. Information about SURAnet/
- 5. Monticello Electronic Library/
- ... snip snip snip ...
-
- This is starting to look familiar.
-
- It turns out that the SURAnet ftp site is also linked to Gopher.
- Instead of having to use a whole bunch of weird ftp commands, we can
- use Gopher to look around the ftp site!
-
- (Note: not all ftp sites are accessible through Gopher. That is why
- I spent all last week teaching you ftp)
-
- Last week we used ftp to get the file fall91.issue from the
- SURAnet ftp site. Let's see if we can do the same thing using
- Gopher!
-
- I move the cursor down to "FTP gateway link to ftp.sura.net", press
- enter, and the following menu appears on my screen:
-
-
- FTP gateway link to ftp.sura.net
-
- 1. README.
- 2. SURAnet/
- 3. archie/
- --> 4. articles/
- 5. books/
- ... snip snip snip ...
-
-
- THIS IS THE DIRECTORY WE GOT THE FIRST TIME WE ENTERED SURANET!!
- Is this cool or WHAT?!
-
- I remember that the fall91.issue file is in the articles menu, so
- I move the cursor down to "articles", press enter, and the following
- menu appears on my screen:
-
-
- articles
-
- 1. editors.box.txt.
- --> 2. fall91.issue.
- 3. spring91.issue.
- 4. sub.form.text.
- 5. summer91.issue.
- 6. winter90.issue.
-
-
- We're in the home stretch now!
-
- I move the cursor down to fall91.issue, press enter, and the following
- appears on my screen:
-
-
- ... snip snip snip ...
-
- On September 11th, SURAnet and MCI completed an agreement
- which will deliver unprecedented benefits to all SURAnet
- members ...
-
-
- Neat, huh?
-
- We just repeated last week's example, only this time:
-
- 1. We did not have to use any weird commands (all we
- used was the up and down arrows, and the enter key).
-
- 2. We were able to see a directory of every menu we passed through,
- and we never had to type DIR.
-
- 3. We were able to read the fall91.issue file without having
- to GET the file, and without having to leave the Gopher
- program.
-
-
- Tomorrow, we'll talk about Gopher commands :)
-
- HOMEWORK
-
- Divide 14,682 by 269 ... by hand (I'm kidding).
- BTW ... I know the answer, so DON'T MAIL IT TO ME :)
