If you want to submit a talk for FrOSCon in June, you will have to hurry: The deadline for the call for papers is approaching.

Talks can be submitted until March, 15th 2006. The organizers ask for talks about free software and open source. Expert knowledge on programming languages, free software on the desktop, security, administration and networks is in demans. Talks about the philosophy of free software and experience with free software in business settings is another focus of the conference.

Besides the conference program, the organizers have a special offer for open source projects: Projects can apply for a developer room at FrOSCon. This room is managed by the project and can for example be used for developer meetings. Members of the project can meet in this room, exchange ideas, socialize and hack code. The conference provides the infrastructure.

Applications for developer rooms should be submitted until March, 31st 2006. Please include the name of the project, the number of participants you are expecting and the URL of the project's web site.

More information about the Call for Projects can be found here, information about developer rooms is available here.

DevShed has posted the last article in their "Enforcing Object Types in PHP" series today - "Using the Type Hinting Feature in PHP5".

[Returning] to the subject of this last tutorial, I'll introduce another method for enforcing object types in PHP 5: the "Type Hinting" feature. It can also be used in conjunction with the "instanceof" operator that you learned about before, in order to develop PHP applications that implement thorough routines for filtering unwanted objects. Generally speaking, when you finish reading this article, you should be armed with a few more methods for forcing object types in PHP, in this way expanding your overall knowledge of object-oriented programming.

They start with an introduction to type hinting and some basic examples of its use. From there, they build up a relevant example with the help of their (X)HTML widget class they've used throughout the series.

The first version of the user manual for eZ publish 3 is now available online. The manual is a non-technical guide for end-users of eZ publish.

On his blog today, Justin Silverton has posted this brief new tutorial covering the use of PEAR's cache_lite package.

Cache_lite is a php/pear caching module that is designed for high traffic sites. It is different than most caching systems because it has a built-in locking mechanism that will prevent cache corruption that can sometimes occur when there are a large amount of concurrent users trying to read and write to your cached data.

He wastes no time getting to the examples, showing first a very basic example of chacing/looking for a cache of your data. There's no installation HOWTO, but if you're familiar with the PEAR system, installation should be a simple matter.

In the past few days I’ve released two new versions of my regular expression datatype for eZ publish, regexpline. Version 1.1 contains these changes: Fixed: CS issues Fixed: Only use internal function to fetch the regular expression Fixed: Naming pattern (title function) does not return an empty string when given no input or invalid input Added: Custom name pattern [...]
