reCAPTCHA for eZ Publish

The other day I came across a site that was using the reCAPTCHA CAPTCHA. I'd heard of the project but hadn't had time to investigate.

The reCAPTCHA project (of the School of Computer Science at Carnegie Mellon University) provides both text and audio CAPTCHAs via a web service. It uses words scanned from books in the Internet Archive that have failed to be recognised by OCR, so using this on your site is helping to digitalise those books. See http://recaptcha.net/learnmore.html for more info on how it works.

With the Christmas break and the fact that we've had an intense low hanging about for the duration (strong winds & rain) I thought I'd check it out and see how easily it could be integrated into eZ Publish.

Turns out it was pretty simple. I've created an extension with a reCAPTCHA datatype that can be used in both regular content class (for forums, comments etc.) and as a information collector (feedback forms etc.). The datatype doesn't store any information but utilises datatype validation methods to check the CAPTCHA and return a pass or fail.

It's an initial version and I've only tested on eZ4.0. Hopefully I'll be able to test on earlier versions in the coming days. Mapping of languages also needs looking at.

For those interested it can be downloaded at http://ez.no/developer/contribs/applications/recaptcha

    Just found this post searching for eZ captchas.

    Thanks for your post (and also -of course- for your contribution, which I just installed in one of my sites).

    I'll let you know if I find coding that needs to be added or changed in order to make it better (though it seems already fine to me) ;o)

eZ Publish Admin Prototype extension

Note: If you enable the extension via the admin interface (Setup -> Extensions) this will effect all site accesses including your front end ones.  Things to check out in the prototype: Lack of Shop and Design tabs - these are disabled by default in eZ Publish 4.3 Hidden right menu.

eZ Publish 5 Virtual Machine

One of the most common issues of newcomers to eZ Publish is the setup of a system suitable for running it. Without a correctly configured system in place they usually do not get beyond the installation process and abandon their evaluation before having experienced the product.  The eZ Publish puppet module is an attempt to codify the requirements  for running eZ Publish and provide a means for automatically creating a system suitable for running it - no more following a checklist of "setting up eZ Publish on XYZ". The eZ Publish 5 Virtual Machine can be found on github at  https://github.com/brucem/vagrant-puppet-ezpublish .   It combines Vagrant, VirtualBox & Puppet to generate a VM with the current eZ Publish community version (2013.4) installed and ready to be configured. The README.md  provides details of the requirements and how to use it. Vagrant is a system that  orchestrates the automatic creation and configuration of s...

eZ Publish Admin redesign - Dashboard = OpenSocial?

Image
In the preface to the current Admin interface specification the last paragraph caught my eye: A overview of user task need a dashboard , where she can follow here own content, approval and other tasks she might do on a regular basis. I recently saw a demo of the latest version of the bug tracking system JIRA 4.0 by Atlassian . It used an OpenSocial dashboard to allow users to customise their homepage to access and interact with information that was important to them.  The system not only displays JIRA widgets but any OpenSocial widgets (and those from other Atlassian products ). You can check out a video of it in action here and more information on how Atlassian is using OpenSocial here . What is OpenSocial? From the official site: OpenSocial defines a common API for social applications across multiple websites. With standard JavaScript and HTML, developers can create apps that access a social network's friends and update feeds. Google personal home page is an example o...
