Email Administration Utility provides an IMAP-based email account management utility.
The Email Administration Utilities package can be used to manage email accounts with a series of PHP-based scripts through a browser.
Addition, Removal, and modification of accounts is possible as long as an IMAP port is available on the mail server.
The Mailadmin project was originally designed to help owners of domains that were hosted by Hub.Org Networking Services. The company wanted users to be able to create, remove or modify email accounts when ever they wanted, giving them a quicker turnaround for Mail Administration Purposes.
As the utility was developed, tested and matured into what it is today, many users requested more features or contributed reports of issues to help improve the utilities stability. Hub.Org has given me permission to release the utility as an Open Source package so that others may also benifit from the simplicity that the Mailadmin utility offers to those who need complete control over email accounts.
With this in mind, I intend to continue development by adding new features as they are requested and fix any issues that may pop up. The more users who use and test the features that the Mailadmin utility offers will help to improve the functionality offered by Mailadmin. I have opened a Sourceforge account to help manage the development and releases of the utility as it matures into what users and developers see the Mailadmin to be.
Main features:
- Administrator:
- Adding/Deleting Email accounts.
- Setting Account Quotas.
- Obtaining Administrative Access Over Older Accounts.
- Changing An Accounts Password.
- Interfaces with the Cyrus IMAP/POP3 server.
- Transaction Log system, allowing you to track changes or to help debug issues.
- Standard User:

- Transaction Log system, allowing you to track changes or to help debug issues.

Server Web Administration Tool is a self-extracting shell script that installs a perl module called Linux::Statistics and a bunch of perl scripts that provide detailed information about a server.
Information includes : memory usage, disk usage, cpu usage, file usage, network usage, swap usage inode and file handle usage, socket information and information about paging on the server etc. There is also a script to check whether a particular process/daemon is running or not.
You can run the script by running "sh swat-1.0.0.sh" as root.
Enhancements:
- This version comes with a bundled installation of the Apache 1.3.29 Web server.

Open Admin for Schools is a School Administration Program. It is a freely available, open source software package and is licensed under the GNU General Public License.
Open Administration for Schools project is entirely web based and can run from a centrally located division wide server or a single computer in a school. It is designed to support an entire division on one or more central computers but can also work just fine for a single school.
Currently several school divisions use this approach and have 15+ schools on a single central server. This is because it is designed to be lightweight both in server resource requirements and in communication bandwidth.
It is secure. Each school has two or more virtual websites and each is protected with password(s). One site, the admin site, is used by the school office and another, the teacher site, is used by teachers in the classroom.
The teacher site also has password access for entering attendance by teachers and also uses cookies that expire in a short period, further limiting access. Another site, a parent/student site, is controlled by parent/student userids and passwords. A fourth virtual site may be used by school liason officers from outside agencies to give them a slightly different access to school information. (Community Schools)
Main features:
- Demographics - It stores student and family information that can be viewed and printed in a variety of ways.
- Attendance - Attendance can be entered either by secretaries in the school office or by teachers in the classroom. It features the ability to do different numbers of periods per day for elementary grades vs high school and middle years. This will allow elementary classes to have 2 classes per day (AM/PM) with a homeroom teacher while higher grades can have attendance done on a per subject period basis (and be subject based). Attendance reports are integrated with report cards/progress reports. A variety of attendance reports are available. A variety of attendance entry methods are available for use by teachers and/or secretaries to allow it to integrate with normal school practice.
- Discipline - A simple discipline module to track student discipline events and track outcomes, etc. Behaviours may be categorized and statistical reports may be printed. Enrollment changes are also posted into this system.
- Report Card System - a flexible reporting system with per subject objectives (up to 20), integrated attendance reporting, etc. All report cards are printed as PDF reports and may include a school logo. All subjects may have unlimited length text comments, and can have any desired ordering. Attendance reporting will now do days open, days enrolled, days absent, and times late as standard.
- IEP (Special Needs) Site that is integrated at the division level that allows special needs teachers to tailor individual student programs that can be viewed from each schools teacher site. This includes the ability to add student medical history, testing done, student teams (and responsibilities), and objectives chosen from lists of thousands, categorized in a variety of ways. There can be up to 32 objectives per subject and each subject is specific to that particular child. His/her program would consist of a variety of subjects in areas such as fine motor control, etc.
- This system can generate progress reports (for use with the report card system) as well as a comprehensive IEP report containing the yearly plan for the child. This IEP can also viewed from the teacher site, to ensure compliance throughout the year.
- Export/Import Modules - to allow students to easily transfer schools within divisions without re-entry of demographic information. Export of data to other programs. Export of data to Provincial authorities via an automated XML based transfer mechanism.
- Saskatchewan SDS support for direct XML transfers of student demographic, subject and enrollment marks to provincial authorities.
- Online Gradebook to allow teachers to enter marks and assessments onine from school or home. It can group and weight assessment items and post directly into the report card system.
- Parent Viewing scripts to allow parents to view attendance, gradebook(where allowed), and report card marks. This is easily integrated into existing school sites.
- Upcoming: Family functions, Parent-Teacher Interview Scheduling, Wherever schools want to go...
- Further out... Multi-language support (demand for a Spanish version exists currently), Student timetabling.
Enhancements:
- A new Fees System to allow fee charging (predefined or new, with various groups), invoice printing, payments and receipts, and the ability to export summary journal transactions to an external accounting program.
- A new teacher logout to remove session data has been added.
- There is a new 70 page User Documentation PDF and a 40 page Administration Documentation PDF (also available in HTML versions).

Template::Tutorial are template toolkit tutorials.

This section includes tutorials on using the Template Toolkit. Subjects currently include an general overview of the Template Toolkit, showing users how to get quickly up to speed building web content, and a tutorial on generating and using data files, with particular reference to XML.

Template::Tutorial::Web

Generating Web Content Using the Template Toolkit

This tutorial provides an introduction to the Template Toolkit and a "quick start" guide to getting up to speed. Its primarily focus is on using the Template Toolkit to build web content and it covers 4 basic areas: using tpage and ttree; using the Template.pm module in CGI scripts; writing Apache/mod_perl handlers; and extending the toolkit by writing plugins.

Template::Tutorial::Datafile

Creating Data Output Files Using the Template Toolkit

This tutorial gives an overview of the Template Toolkit, showing in particular how to use it to read and write data files in various different formats and styles. It was written by Dave Cross and first appeared as a lead article at http://www.perl.com/ earlier in the year (2001).

Gantry::Docs::Tutorial is a Perl module for The Gantry Tutorial.

Gantry is a mature web framework, released in late 2005 onto an unsuspecting world. For more information on the framework, its features and history, see Gantry::Docs::About.
Here we will explore the basic workings of Gantry by constructing a very simple application. Dont let the simplicity of this example fool you -- this framework has extreme flexibility in delivering applications with web and scripted components. The example in this document is only to get you started.

This document begins by describing a simple one-table management application. It walks through the process of building the application. Then, it shows a tool -- called Bigtop -- which can be used to build the application from a relatively small configuration file. Finally, it shows how to add another table and regenerate the app via Bigtop.

All System Info is a system info SuperKaramba theme. Simple english version...
It shows:
- System Info
- CPU usage
- Network Usage
- Memory Load
- HDD usage

XML::Smart::Tutorial is a Perl module with tutorials and examples for XML::Smart.

SYNOPSIS

This document is a tutorial for XML::Smart and shows some examples of usual things.

Template::Tutorial::Datafile is a Perl module for creating Data Output Files Using the Template Toolkit.

This tutorial gives an overview of the Template Toolkit, showing in particular how to use it to read and write data files in various different formats and styles. It was written by Dave Cross and first appeared as a lead article at http://www.perl.com/ earlier in the year (2001).

Introducing the Template Toolkit

There are a number of Perl modules that are universally recognised as The Right Thing To Use for certain tasks. If you accessed a database without using DBI, pulled data from the WWW without using one of the LWP modules or parsed XML without using XML::Parser or one of its subclasses then youd run the risk of being shunned by polite Perl society.

I believe that the year 2000 saw the emergence of another must have Perl module - the Template Toolkit. I dont think Im alone in this belief as the Template Toolkit won the Best New Module award at the Perl Conference last summer. Version 2.0 of the Template Toolkit (known as TT2 to its friends) was recently released to the CPAN.

TT2 was designed and written by Andy Wardley. It was born out of Andys previous templating module, Text::Metatext, in best Fred Brooks plan to throw one away manner; and aims to be the most useful (or, at least, the most used) Perl templating system.

TT2 provides a way to take a file of fixed boilerplate text (the template) and embed variable data within it. One obvious use of this is in the creation of dynamic web pages and this is where a lot of the attention that TT2 has received has been focussed. In this article, I hope to demonstrate that TT2 is just as useful in non-web applications.
