Ara is an automatic editor of RSS feed. Only the links towards the Web pages must be given to him. The project is able to retrieve the title and the description of the pages and to produce a syndication file in the RSS format.

It enables you to select the pages to be syndicated instead of publishing the last articles systematically as the generators included in content managers do it.
The Ara term means "Atom and RSS API", it is also the name of a species of parrots from South America.

Using Ara

The program is a set of PHP scripts which have to be stored on a Web site. One creates a feed from the browser by entering the URL of the interface, ara.php.
It is easier to use the program with two browsers, one to display the pages to include and to copy the URLs from the URL input field, the other to edit the RSS file. Thus by just a cut and paste action one transfers the URL from the field to the interface and one clicks on "Add" to add it to the list.

The EDIT button on the left of the link makes it possible to modify the title and description if one wants.

To generate the feed, one enters the nam.

Warning
Ara is not a simple editor, when a page is added, it is reads for extracting useful information and for this purpose Ara makes use of Ajax (with the Anaa framework ), but Ajax can read files only from the site where it is installed. Actually the goal is to build the feed of the site, just avoid to give URL to other sites.

How it works

It is an Ajax script with a backend in PHP 5. In the current version only the pages of the website where it is installed can be added to the feed.

It is necessary to be authenticated to use it, to this goal the install.php program allows to register a login and a password. This file must absolutely be be erased. Once registered, the user remains registered for the whole session, even if he reads other pages meanwhile.

To generate the contents automatically, the program loads the pages given in the list and reads in the head section the contents of the title and description tags. If they are missing, the first H1 tag in the body of the page will be used for the title instead.

The same if description misses, the text of the synopsis will be taken from the page instead.

Simple Equation makes it simple to put equations on the Web. Simple Equation project does not bother the user with the layout of the equation; it just displays it. The focus is on being simple to use.

One of the biggest obstacles to using mathematical expressions on the web is that the user currently needs to worry about layout. Web users should not have to learn a layout engine.

The class is built as a recursive parser. It is pretty easy to add operations to the parser, but it will not scale to a huge set of operations. That is OK, we want to keep things simple. At some point a layout engine may be required for a complexity level. This is not a layout engine.

Currently, only graphical output is generated, but it is hoped that MathML output can be generated automatically if the browser supports it instead of the graphic.

Site Editor is a CGI script which allows a user to manage their web space without needing ftp access.

With only a web browser you can browse your web space, edit text files, upload files, and create and remove directories. Site Editor also has ZIP support making it easy to grab an entire directory tree.

Site Editor is completely functional but is missing some features and polish which would make it easier to use. Currently it requires access control to be handled by the web server. On top of this the code is a little raw, hence this is not a 1.0 release.

To configure for your system the "site_editor" script needs to be modified slightly. In the "Config" section edit the following variables:

$BASE_DIR Root directory for editing files.
$BASE_URL Web location for $BASE_DIR files. Can be relative or absolute.
$TITLE Title prefix to be used for each page.
$ICON_URL Location of icons. It may be relative or absolute.
$ZIP The full path to your Info-ZIP binary. Comment to disable.

I have included a simple patch to Apaches suexec which will allow the script to be root owned. With suexec and the script owned by root the user wont be able to modify the scripts configuration but will still be able to create and modify their own files.

Any comments and suggestions are welcome.

keyTouch makes it possible to easily configure the extra function keys of a keyboard (like multimedia keys). keyTouch it allows the user to define which program will be executed when a key is pressed.
