A free Basic UNIX-training with muLinux


Notes: This Text is roughly translated (German to English) by a translating program. Sorry, but I have not time for the translation. Maybe you can do this.

The WWW Browser Quark

Above all it is to be owed to the World Wide Web that that became so popular Internet today. The simple operation with the Surfen enables to get it to everyone without many previous knowledge the correct information from the Internet. Besides the Web became Sites optically more attractively in the last years. Every now and then however the clarity suffers from it. Site by the way means in English property, area, place or workstation. Please not with side (English for lateral) mistake.

Over of hyper+link too hyper+link to surfen needs one a WWW Browser. The Browser (English for schmoekern, regard) must understand hypertext transfer Protocol (HTTP). Usually the Browser controls also still different logs (Gopher, ftp, E-Mail, Wap...) and Technologieen (JavaScript, Flash...). Unfortunately so far no Browser adheres perfectly to the given standards.

The gebraeuchlisten Browser is the Internet Explorer of Microsoft and the Netscape Communicator. One spoke until recently over-bid by a Browser war, since Microsoft and Netscape did not standardize themselves mutually by new, usually, features. The Internet Explorer is used at present at most. However the development does not stop.

AOL took over Netscape, which became source code of the Netscape Communicator however as open SOURCE defined. This Browser is developed further now as Mozilla ( http://www.mozilla.org). It is written almost by reason on new. Target is to be adhered as perfect as possible it to the standards. Further the Office package Staroffice (http://www.sun.com/products/staroffice ) is likewise available to open the SOURCE and thus freely. (there are actually still people those the perfectly made too expensive M$-Office buys?) StarOffice has also a WWW Browser. So the open SOURCE municipality has to initiate good cards a new Browser generation.

Increasingly more use the Browser Opera ( http://www.operasoftware.com ) finds to these is very slim and fast. It is untersuetzt at present the only Browser that directly also WAP. The Wireless Application Protocol is used by Wap fahigen mobile telephones, in order to suerfen in the Internet. WAP is very similar to the HTML. By the small bandwidth the representation is very much text-oriented. One returns thereby again to the roots of the Internet. ;-) An Java applet to the Surfen with WAP finds under the address http://www.space2go.de/html/demo-ps.html

A shadow existence had so far the purely text-oriented WWW Browser lynx . In addition, its disadvantage, no diagrams or nerve-ends Flash animations to display to be able, is its advantage. It is with distance the fastest Browser. lynx heard to the scope of supply of most Linux versions. It gives also lynx for DOS , Windows and Mac.

Each Web designer should creates Website also also lynx test. Whereby it does not depend thereby on the beauty. Important it is itself by the Site also lynx navigate to be able. I know the opinion of many Web designers: " Why should I mean Site with such an ancient Browser to test? " I want to convince over sake sky none here this to do. Times apart from the fact that lynx - it is constantly developed further - has it is not ancient a substantial advantage.

[Netscape Fehlermeldung]
Unfortunately possess lynx and quark no such graphic surface.

lynx the Website sees just as as most artificial surfer, i.e. as the search machines. These go leaving very very essentially to the work and not from beautiful Multimedia applications to impress itself. In the opposite. The search machines understand only pure HTML left with JavaScript, image maps or Flash are usually insurmountable obstacles. Also the Frame technology, which becomes extinct obviously slowly again, can prove for the popularity of the Website as very harmful. Each Web designer should normally make the Site for all Browser usable.

Best viewed with any browser

So, now I have so the boost for lynx agitated, this section dedicates itself however to a Browser named quark . Why? We start quark simply times. 

/# quark

                              Web Micro Browser v 0.2

                 (C) 1998 M. Andreoli, Rustic Software Foundation.


                  netscape-v4.02        size 8486176  bytes
                  mosaic                size 2745372  bytes

 cursor up/down, pag up/down to move                       vxx, hyperlink mode

The problem for Michele Andreoli is probably the lack of space on a muLinux diskette. In earlier muLinux versions belonged lynx to the scope of supply. Now is lynx on an ADD on diskette. We return therefore later to him. The size of (English size) of lynx occupied with 470,664 kbytes simply too much workstation. Michele Andreoli programs probably everything briefly and small.

Operation

With the programming of quark it has itself at the operation of lynx oriented. Who quark to serve can, also comes along lynx by right. There a mouse at the disposal takes place the operation is not to us (still) by means of the keyboard. Who the few keyboard contractions knows is faster than with the mouse.

   [q]    [ q]uit

In the section " of the Web servers PYGMY " we have already the meaning of the key q become acquainted with. Thus becomes quark terminated.

Start with URL

One can quark also equal the URL as parameters transfer. URL is for uniform resource Locator and is " a map reference " in the Internet. A URL consists of a log (e.g. HTTP, ftp, telnet, Gopher, news, mailto, file), the drawing sequence "://", a host name or an IP address, as well as (optionally) the directory or a Dateienamen. quark control the following logs:
  •   file://
  •   http://
  •   ftp://
  •   mailto:

/# quark http://localhost

The local Web server must have been activated in addition.

           Picture up/down

The move forward and back by page take place with the keys Screen up/down.

[Cursor hoch]    [Cursor runter] From URL to URL branch

With most WWW Browser unfortunately the possibility from URL for URL is missing to branch. This is however very practical.

   [u]    [ u]rls    - URLs of the document list

Likewise conventional WWW Browser does not have all URLs of the current HTML file the ability to list. With q one leaves this display mode again.

   [h]    [ h]elp    - assistance

Before we the assistance of quark to use, change we want into the second console also [ Alt][F2 ] , log in us and start quark . Opposite other WWW Browsern can quark do not open a new window, in order to open another URL e.g. at the same time or assistance give themselves. We go around this, by we on the second console quark again start.

The assistance text appears to the key after pressing h . With the cursor keys we can move in the short text and these if necessary again also q left. The simple operation of quark requires no long assistance texts. Interesting which one here something to quark - technology experiences quark uses the " NetCat " port scanner to gets the HTML files and classical UNIX text Tools how sed , tr , awk , and m4 for conversion HTML >txt. Here the advantages of Unix become effective. Small, reliable Porgramme can be assembled for complex functions such as modules.

   [g]    [ g]o    - URL input

To input the URL serves g as contractions for go (English for goes). We leave in addition the assistance or change back to the first Kosnole. After we g to have input we can input the URL in the lower line. So z. B.

URL: file:///usr/quark/Logo

   [b] or [Cursor links]   [ b]ack    - back

Over again at the last file to arrive one presses b or the left cursor key

   [r]    [ r]eload    - new load

If the page should have changed in the meantime, one can also r the display refurbish.

   [v]    [ v]iew    - source code display

Who the HTML source text to be displayed to be able wants can this also v do.

   [s]    [ s]ave    - memory of the current HTML file

For storing serves the displayed HTML file s .

   [d]    [ d]ownload - link download

If link is current, the gelinke document can also d are downloaded.

   [P]    [ P]rint    - printing

Zus printout of the current document serves P .

For People Who want to Know More

Who itself gladly times the source code of quark to look at wants: 

/# vi `wich quark`

Notes to Netscape / Mozilla / Explorer

Some remarks for users of conventional Browser.

Banner stop

Every now and then banner advertisement on WWW Sites nervt. There are possibilities these to filter. A simple version is to be assigned the appropriate AD server ( ad vertise, English for advertisement) easily the local IP address. In addition the file must / etc./host are edited. With Windows this is also possible (Win9x - c:\window\hosts , Windows NT - c:\winnt4\system32\drivers\etc).

***TRANSLATION ENDS HERE ***

Vielleicht fragen sich einige warum Netscape Stop? Die deutsche Version von Netscape (auch in der Version 6) nimmt nach dem Start erst mal Kontakt zu kundenserver.de auf. Das muß ja nicht sein.

Eine umfangreiche Liste befindet sich in http://feh.net/adblock/adblock.shtml .

Cookies in den Müll bei Netscape

Wer keine dauerhafte Cookies auf seinen Rechner haben will, kann die Datei cookie löschen und diese als Link auf den Unix-Mülleimer wieder anlegen. 

ln -s /dev/null ~/.netscape/cookies
