  • There are numerous GIT workflow floating around like Centralized Workflow, Gitflow, Forking flow and Feature Branch Workflow

    Over the last 10 years, I have followed this really simple workflow, similar to the forking flow.
    • it allow Parallel Development, features branches can be merged to any release branches or ideally Master
    • Collaboration Feature branches also make it easier for two or more developers to collaborate on the same feature

    We consider Master the stable version of the product, this branch should be deployed automatically using continuous delivery

  • Agile testing is a software testing practice that follows the principles of agile software development. Agile testing is built upon the philosophy that testers need to adapt to rapid deployment cycles and changes in testing patterns. Providing and getting feedback early, fast and regularly is one of the testers main task.

  • joomlaloveRAD

    Rapid application development (RAD) is a software development methodology that uses minimal planning in favor of rapid prototyping. Something that was really slowing me a lot and making any builds or changes in my extensions a real pain to maintain was the packaging of code spread in the joomla tree. I did create numerous custom Phing builds to automate and reduce these pains (Phing is heavily derived from Apache ANT) and  2 months ago  Joomla-packager was born!

    My Joomla-packager is a generic Phing build script to build any Joomla 3rd extension, being a set of components, modules, plugins and or libraries, packages in a simple way.


    Developers of 3rd party extensions for Joomla

    Convention over configuration…

    • A single script to rule all your need of Joomla packaging: multi modules/ multi plugins/multi components/multi library is supported,
    • If you respect Joomla conventions, this packager will be able to create a build of any of your extensions or set of extensions,
    • just configure one file (like for example in buildCedThumbnails.xml), mainly listing what your extension is made of and run with minimal efforts,
    • Packaging Joomla extensions will always look look the same = repeatability = convention over configuration


    1. Download locally
    2. Download a copy of buildCedThumbnails.xml You only need to rename and touch this file, it is self documented.
    3. Download a copy of pkg_cedthumbnails.xml You only need to update this file if you alter the structure. (later Joomla-packager will create this file on the fly)
    4. Run the main target build of buildCedThumbnails.xml

    How it is working?

    This script implement ALL standard Joomla conventions to perform the packaging, and offer reusable Phing targets to package any number of extensions. Here is what is implemented:


    • 1. Code is located in /modules/mod_${xxxxx} and self contained
    • 2. Languages files are optional but if they exist are located at /language/xx-yy/mod_${xxxxx}.ini /language/xx-yy/mod_${xxxxx}.sys.ini
    • 3. Media files (css,js,images) are optional but if they exist are located at /media/mod_${xxxxx}
    • 4. name of zip files as follow:
      • mod_{yourextension1}.zip


    • 1. Code is located in /plugins/${type}/${xxxxx} and self contained
    • 2. Languages files are optional but if they exist are located at /plugins/${type}/${xxxxx}/language/ or anywhere else in directory at step 1.
    • 3. Media files (css,js,images) are optional but if they exist are located at /media/plg_${type}_${xxxxx}
    • 4. name of zip files as follow:
      • plg_${type}_{yourextension}.zip


    • 1. Code is located in /administrator/components/${xxxxx} and /components/${xxxxx} and is self contained
    • 2. Languages files are optional but if they exist are located at /administrator/language/xx-yy/${xxxxx}.ini and /language/xx-yy/${xxxxx}.ini and
    • 3. Media files (css,js,images) are optional but if they exist are located at /media/${xxxxx}


    • 1. one zip file which contains 1 to n other zip file + a manifest file named pkg_{yourextension}.xml
    • 2. manifest file named pkg_{yourextension}.xml has to be written manually for now and place beside your build{yourextension}.xml
    • 4. name of zip files as follow:
      • com_{yourextension}.zip

  • In this series of post I will outline some common techniques to help Joomla extensions development.

    As you know Joomla is shipped with Mootools library which assign $ also to Ajax. Here is 2 tips that will allow you to use jQuery scripts without any modifications (most of the time you will find tips to assign jQuery to something else than $ and rewrite your scripts)

    First it is recommended to include always mootools first to avoid jQuery conflict issues

    $document = JFactory::getDocument();
    $document->addScript(JURI::root() . "media/com_cedtag/js/jquery.1.7.2.min.js");

    then to run jQuery in noConflict mode. Note that here I do not assign jQuery to any alias.


    Till here, this is what you will find on all Joomla forums, posts over the internet. The last tips is what make the difference!

    Instead of using a different alias for the jQuery object (when using noConflict), you can write your jQuery code by wrapping it all in a closure. This can be done in the document.ready function

    $script = "jQuery(function($) { $();

    });"; $document->addScriptDeclaration($script);

    This way you are not force to rewrite your scripts to use another alias (replacing $ with jquery alias for example in all your scripts). This make inclusion of jQuery really easy!

    Happy Coding!

    jocomment I did install yesterday evening the latest version of !JoomlaComment

    !JoomlaComment is one of the first extensions for Joomla,that let you comment under articles.

    The !JoomlaComment system can be installed on any joomla website within seconds! Make
    your website more interactive!

    Main Features:

    • ajax-based
    • captcha protection
    • akismet support
    • ubb code support
    • threathed/nested comments
    • multilanguage support
    • mail, website input
    • See more features here

    Joomla support templates, depending on which templates you use

    • MTdefault-emotop, these templates MTxxxx use mootols 1.11
    • JQdefaut-emotop, these templates JQxxxx use Jquery
    • ..

    You may behind the scene include another additional AJAX library in Joomla!® frontend, this lead to performance issues:

    If !JoomlaComment use JQuery 1.1.4 and not the AJAX library of Joomla!, aka Mootools 1.11. Another huge JavaScript files that make my server busier!

    Since any static files can be offloaded to another server to gain more speed. For example, any static images, JavaScript or CSS files can be moved to a different server for more speed.

    In order to be able to offload this JavaScript library to Google code, you’ll have to do the following:

    In the template you are using, for example in components/com_comment/joscomment/templates/JQdefault-emotop/index.html

    Search for

    <script type="text/javascript" src="components/com_comment/joscomment/jscripts/jquery-1.1.4.pack.js"></script>

    and replace with

    <script type="text/javascript" src=""></script> 

    Note that I use here the latest JQuery version (1.3.2) and not the default version of !joomlaComment (1.1.4), here is why

    • This version 1.1.4 is not available at jquery"> :-)
    • I did test the frontend of !JoomlaComment 4.0 with JQuery 1.3.2 and it work great

  • I am searching such a solution since 2 months...
    It is not a graphics card. Rather it is a palm-sized box that sits outside of your system. DualHead2Go takes the existing single monitor display output (i.e. external VGA output) from your system and expands it into dual display outputs, allowing you to run your Windows desktop at up to 2560 x 1024 resolution stretched across two displays. Using DualHead2Go in conjunction with the built-in display of your laptop, you actually benefit from 3 displays at a time.

  • "For more than 50 years software has been a troublesome discipline. Software's problems are numerous and include cancelations, litigation, cost overruns, schedule overruns, high maintenance costs, and low levels of user satisfaction. The problems with software occur more often than not. My company's research indicates that more than half of large software projects will encounter some kind of delay, overrun, or failure to perform when deployed. But software does not have to be as troublesome as it has been. Some complex software projects do achieve their delivery schedules and cost targets, and behave properly when used. Throughout my career in software I've been interested in what distinguishes successful software projects from failures and disasters. It happens that the main factors leading to software success are easily identified when side-by-side comparisons of similar projects are performed, where one set was successful and the other set was troublesome. The successful software projects achieve excellence in software quality control, and they are able to do this because of excellence in software quality measurements. Although it might be thought that excellent software quality control is expensive, it turns out to yield a very positive return on investment. When canceled software projects and disasters are studied by means of "autopsies," they all have similar patterns: Early phases of troubled projects are handled carelessly without adequate requirements analysis or design reviews. After rushing through the early phases and seeming to be ahead of schedule, problems begin to mount during coding and testing. When testing begins in earnest, serious problems are detected so that schedules and cost targets cannot be achieved. Indeed, some software projects have so many serious problems—termed bugs or defects—that they are canceled without completion. By contrast, successful projects are more thorough at the start. The requirements are carefully analyzed and the designs are formally inspected. This takes some time and adds upfront costs, but once coding and testing begin, the value of careful quality control allows the projects to move rapidly to a successful conclusion. Stephen Kan and I both learned the importance of software quality control and good software quality metrics at IBM. Even though Stephen and I worked in different IBM labs during different decades, we have some common viewpoints. We have both been convinced by empirical evidence that without excellent software quality control, large system development is hazardous and likely to fail. We also both know that effective software quality control is built on a foundation of careful measurements using accurate metrics."

  • More sites using Google maps:

    And If You have a good idea and want to develp our own application  using Google Maps, You may ask How it works...

    Google maps is using Javascript, XML, XSLT, and CSS to create a web application that behaves more like a desktop application. With normal web programming, the user is presented with a form, the user inputs its data, the user submits the form, and finally the entire web page reloads with new content. AJAX, as this type of programming has been coined,  does not require the reloading of the entire interface.  The Javascript is able to make calls back to the server to get the required information and update only those parts of the interface that needs to change.

    You can start by registering for a key HERE, and start reading all blogs describing hacks an tips, for example:

    • Google Maps Mania: An unofficial Google Maps blog tracking the websites, ideas and tools being influenced by Google Maps.

    mod_pagespeed is the latest addition to our family of products, performing on-the-fly optimization in the Apache™ 2 HTTP Server. It provides webmasters and web developers that manage their Apache 2 configuration with technology that applies Page Speed performance best practices automatically. Webmasters can get the benefits of the optimizations without having to manually going back and fixing the performance issues that Page Speed detects.

    This solution is valid if you do not want to carefully optimize your site, and it come for now at huge initial CPU costs till the cache is filled up. The load on my server has proven to be unacceptable (for me) and I was forced to switch it off. But it may work on your server depending on the page size, number of visitors. Authors are working hard and communicating a lot on the official mailing list to reduce that load and improve the code in the coming weeks

    If you trust me, you can download the library module for Apache 2.2


    Check before installing the MD5 keys of this file

    # md5sum -b
    187995e3623a222ec5b54c331ee7ffaa *

    If it matches, drop it into your Apache library folder /usr/lib64/apache2/

    Build Apache module mod_pagespeed yourself

    On my OpenSuSE system, I was forced to install first

    zypper in gcc-c++

    Then read

    you should get after a successful build

    • ./out/Release/
    • ./out/Release/install/common/pagespeed.conf

    Install the module library

    cp ./out/Release/  /usr/lib64/apache2/


    After installing mod_pagespeed, it can be customized and configured by editing the Apache configuration file


    so you can run

    # cp ./out/Release/install/common/pagespeed.conf /etc/apache2/conf.d/pagespeed.conf

    Create some directories

    # mkdir /var/mod_pagespeed/
    # mkdir /var/mod_pagespeed/cache/
    # mkdir /var/mod_pagespeed/files

    Has to be writtable by apache

    chown -R wwwrun:www /var/mod_pagespeed/

    and finally restart apache

     apache2ctl restart

    There is a lot of available settings that are all well explained in this page

    Here is my /etc/apache2/conf.d/pagespeed.conf stripped of all comments as an example:

    Full support for Joomla 3.1 has been added to the project “Schema Validation for Joomla Extensions” (GitHub), tested with all 113 manifests of Joomla 3.1.5! (components, modules, plugins and templates)

    Without them, Joomla accept any entry in manifest xml and never complains about

    • Mistyping, like a valid xml but that the Joomla installer do not understand or only partially,
    • Wrong constructs, xml tag child misplaced,
    • Invalid data type, like a path not being a valid path, an expected integer being a text and so on…

    Joomla just silently die during install or install only partially extensions. These days are over and all developers with any decent IDE will be able to

    • Validate while typing,
    • Enjoy auto completion.
    • Have an up to date documentation of all possibilities in Joomla’s manifest.

    config.php is a custom or a copy of your configuration.php

    For your convenience, I provide a zip file (, unpack in your Joomla root and you’re done.

    Note when using PHPUnit 3.6 , Joomla should not need to include/require anything PHPUnit related since (at least) PHPUnit 3.6. This create errors otherwise.

    In PHPStorm

    Set Up PHPUnit

    Go to Settings, using CTRL+ALT+S, under PHPUnit, select the option “Use Bootstrap file” and use as value ${joomla_root}\tests\unit\bootstrap.php

    Set Up PHPUnit Skeleton Generator

    Go to Settings, using CTRL+ALT+S, under “Skeleton Generator”

    • Enter for “Path to phpunit-skelgen” the value is  ${xampp_root}\php, for example C:\xampp\php
    • Enter for “use bootstrap file” the value ${joomla_root}\tests\unit\phpunit.xml

    Your first Joomla test case

    Create a test case from any of your Joomla classes, by hitting CTRL+SHIFT+T, this will let you select the method you want to test and generate a runnable albeit incomplete test classes.

  • Bug Tracking Tool
    Work in progress

    or Why it is not possible to manage any software development without a bug tracking tool

    A bug tracking system is basically a database linked to  a frontend:
    • The frontend can be a FAT client, understand a windows or application running on your pc and that need to be install by each developer/client, or may be
    • Adhering to a light client server model: HTML frontend which submit queries to a server.



    When was the bug open, and closed, what is its status now. Who has reported it (login is required and all system support profile (user, tester, manager, developer, administrator) and/or isolation of project). Did It already existed in a previous version (regression in code), etc...


     Easily dispatch responsability or find quickly who was reponsible for solving it, how  much time was needed to close this bug, some system may send email automatically to developer to inform them... etc...


    How difficult will it be to solve this issues, (can be a bugnote add by other developer). Most of the time, technical leader decide of the value of this field together with developers.


    How many bugs are still open at a date "t", how do I determine the order in which I will solve them...etc

    Standardisation of records

    By forcing tester/customer to enter some mandatory fields in a graphical forms. It may avoid You to hear some ridiculous statement like: "the application is not printing, working". It force the user talking a language You have decide together, having agreed on a "bug category" list is a very good and common example.


    All modern bug tracking tool let You define and customize some part of the system according to your need.

    Addition of information

    A screenshot is better than thousand word, a file create by the application, a memory dump, anything that will help developer to reproduce the bug.


    A lot of very powerful queries can be executed. It is always interesting to know, how many improvement were done in the next/past releases, or if a team has use more power to develop new functionnalities (also changes request which interest the customer the most) or loose time tracking some low level bug priority.
    In case of reporting, Bugzilla support the following:
    • Tabular reports - tables of bug counts in 1, 2 or 3 dimensions, as HTML or CSV.
    • Graphical reports - line graphs, bar and pie charts.

    Al of the above will have a positive result on:
    • communication among the team of developers and customers,
    • It will improve the product quality by several magnitude,
    • Developer will be more productive as the will know what to concentrate on or what is worth to do.
    AND Your customers will be happier!!

    Golden rules

    1. A bug that can be reproduce can be analysed/corrected.
    2. Correcting a bug is not always trivial, a correction may introduce new bugs.
    3. The intrinseque quality of a software is always improved with a tracking tool over time

    Some open source software:

    Bugzilla ( is the more famous, use in a lot of open source application (Mozilla, Apache, and even eclipse) version 2.19.2 (MySQL+PHP, Solaris, Linux, Win32, MacOS X, BSD) 370 companies are currently using it. (Nasa, IBM, Mozilla and others)- Wikipedia has a very brief article on it, Features are listed here

    Mantis. ( A very simple bug tracking tool with limited search functionnality compared to bugzilla, a strong community but not so much stable release as expected.

    Buggit ( no new release since 2000 and bounded to MS access, aka running only unde windows. Listed Here because I use to play with it in 2001.

  • There's a new version of Xdebug released which fixes a major bug where inspecting static properties caused Xdebug to crash in XAMPP 1.8.0.

    Unfortunately, you’ll need to update manually the version of Xdebug shipped with XAMPP to Xdebug 2.2.1 rather than 2.2.0:

    Simply download the correct Xdebug binary (VC9 threadsafe PHP 5.4 VC9 TS (64 bit) (MD5: 81cacc87168c99c7f65ba202dc12c4b2)) and copy it in your XAMPP installation at xampp\php\ext\php_xdebug.dll

    restart Apache and you can continue debugging!
