The Frequency Clock Free Media System

Version 1.0 of a new open-source multimedia system known as The Frequency Clock has been announced. "We are very happy to let you know about a new open source software system which has been released today, which is a powerful mechanism to manage and control 'channels' of audio and video online. Its designed especially for not-for-profit organisations and the cultural sector, but can be used by anyone who has online audio and video."

The components of the Frequency Clock consist of:

• A Program Database: for containing information about live and pre-recorded programs.
• A Timetabling System: a tool that allows programs to be placed into the program database for scheduled playback.
• A Streaming Media Player: a multi-platform web-based scheduled audio/video playback application.

See the Functionality List for more details.

The system can be used to produce online channels of streaming video and audio for web sites. Media files can be chained together in a schedule for playback by site visitors.

One of the design goals is to have the Streaming Media Player be able to play a wide variety of streaming media formats such as WindowsMedia, Real, and Quicktime, allowing it to replace a collection of proprietary players.

The system has been designed for the following users: "community radio stations, community cable television operators, film and video organisations, museums and galleries, filmmakers and documentary-makers, artists, DJs and musicians."

The Frequency Clock looks like a well thought out system, be sure to check out some of the screen shots on the main web page.

Learning the New Jakarta Struts 1.1, Part One (O'Reilly)

Sue Spielman covers Jakarta Struts 1.1 on O'Reilly. "Over the last year, the Struts framework, a Jakarta open source project, has become practically the de facto standard for building Web applications. Based on the MVC architecture, Struts has proven to be a solid framework that can be used on systems of all sizes. In fact, I’d be hard-pressed to come up with a reason why you and your development team should spend cycles developing a custom MVC framework for a project. It just doesn’t make sense."

PHP Cookbook Trip Mapping with PHP (O'Reilly)

One of the distinctive images was a thick red line cruising across a map, showing Indiana Jones' routes when crisscrossing the globe and fighting bad guys. I don't think they used PHP for any of the special effects in 1981, but you can use PHP today to create a similar map of the United States. "

W3C Advances XForms 1.0 (Dr. Dobb's)

Dr. Dobb's covers the release of Candidate Recommendation 1.0 for XForms. "XForms is seen as the foundation for next-generation Web-based forms, using XML to make it possible to write forms in a number of markup languages and deliver them to diverse devices, from PDAs to cell phones and screen readers, without having to rewrite the forms. The specification achieves this by giving authors the ability to distinguish the descriptions of the purpose of the form from the presentation of the form and how the results are written in XML."

Its value attribute lets you name the number to insert, but if you really want to add a specific number to your result, it's much simpler to add that number as literal text."

The Zen of Comprehensive Archive Networks (use Perl)

use Perl has an article that describes some of the work behind developing a language archive site such as Perl's CPAN. "It seems that there is a lot of interest in having similar archives for other languages like CPAN is for Perl. I should know; over the years people from at least Python, Ruby, and Java communities have approached me or other core CPAN people to ask basically 'How did we do it?'. Very recently I've seen even more interest from some people in the Perl community wanting to actively reach out a helping hand to other communities. This 'missive' tries to describe my thinking and help people wanting to build their own CANs. Since I hope this message will somehow end up reaching the other language communities I will explicitly include URLs that are (hopefully) obvious to Perl people."
