2 weeks from now, 28 November 2014, The imitation game movie will hit the cinemas and we'll watch Alan Turing's (Benedict Cumberbatch) story about the period during the World War II, and breaking the Enigma code at Bletchley Park. In this clip he is interrogated about his role in that and he explains the machine consciousness.

This website is not intended for movies, but any programmer's / software engineer's dream is to create or, at least, to work with an artificial intelligence. A machine who's more than software and hardware, who's capable of intelligent thoughts and rational thinking. So, this clips is (or it should be) an exception.

You have heard about Shellshock Bash bug, right? It affects the machines running Linux and / or Mac OS X (including your PC's, web servers, your smartphones, some of your devices at home) by making them vulnerable via the Unix command shell Bash, which happens to be one of the most common applications in those operating systems. The shell or command prompt is a piece of software that allows a computer to interact with the humans by interpreting text typed via the keyboard. A malicious user can get access to your input and inject code to the system, taking control or damaging it and its data.

This bug was baptized Shellshock by Security Researchers and you can find more information about it over here. This issue is not critical, but it can create severe problems. Keep yourself informed and watch for updates... then updated your computer / server / smatphone and other devices as quickly as you can.

Let's start with your computer. If you have a Mac OS X or Linux system, open the Terminal and run this line of code:

env x='() { :;}; echo Shellshock Bash makes you vulnerable' bash -c 'echo this is a test'

If you see the text "Shellshock Bash makes you vulnerable" as an answer, your system is, well... vulnerable. Three of the most popular Linux distributions, Fedora, Red Hat and Ubuntu already have patches available, probably Apple will soon release its fix.

Somebody asked me yesterday what have to be done in order to disable copy/paste function and to stop the visitors (or, at least, most of them) to copy the content of her articles. Well, I prepared the answer, but you can learn from it as well... So I am posting it here, hoping it will help.

Apply this code in your html document inside the <body> tag in order to disable drag and select (and copy/paste using the Ctrl+C/Ctrl+V keys).

ondragstart=’return false’ onselectstart=’return false’

Practically, the tag should look like this (considering there is no onLoad or other stuff like that already added):

<body ondragstart=’return false’ onselectstart=’return false’>

Apply this script in your html document before closing after the starting and before the closing the <head> tag:

<script type="text/javascript">var message=FunctionDisabled!;function clickIE4()
{     if(event.button==2) { alert(message);returnfalse;}}function clickNS4(e)
          {if(e.which==2 || e.which==3) { alert(message);returnfalse;}}}if(document.layers)
     document.captureEvents(Event.MOUSEDOWN); document.onmousedown=clickNS4;}elseif(document.all&&!document.getElementById)
    { document.onmousedown=clickIE4;} 

Add some necessary security CSS elements to the <body> tag.

For example, add in the CSS file

body {
    user-select: none;
    -moz-user-select: none;
    -webkit-user-select: none;
    -o-user-select: none;

In case you want to place them as CSS style in the html document, the <body> tag will look like this:

<body ondragstart=’return false’ onselectstart=’return false’ style=’user-select: none; -moz-user-select: none; -webkit-user-select: none; -o-user-select: none;>

This is basic protection only! That will help you in most of the cases, but advanced users will bypass it with ease by disabling JavaScript on their browser or using firebug to see the html source.

A few months ago I wrote about this error that appears when someone is trying to install a module, extension or template design for previous Joomla versions. It's not the single time when this warning appears when trying you're trying to install or upgrade something.

Let's take for example the following code:

<?xml version="1.0" encoding="UTF-8"?>
<extension type="module" version="3.0" method="install">
<name>Joomla SlideShow</name>
<author>Supravirtual SRL</author>
<copyright>(C) 2013 webdesign-software-code-seo.com. This module is released under the GNU/GPL v2 License</copyright>
<authorEmail>This email address is being protected from spambots. You need JavaScript enabled to view it.</authorEmail>
<description>Joomla horizontal and vertical Slideshow</description>
<license>http://www.gnu.org/licenseses/gpl-2.0.html GNU/GPL</license>

The  XML file continue with the rest of the necessary code for a module. The error what I am referring to appears when one is changing the "and" from description to "&". Everything else is OK, the code is OK, but you can't install or upgrade your Joomla extension as long as you are using & in the file.

Especially useful information for beginner web designers... just watch the video and you will understand why.

Joomla 3 is out for more than a month now. If you already upgraded your existing Joomla (or made a clean install) to the latest version you might have had a little surprise when you tried to install a new package (component, module or plugin) or to update a new one.

Warning JInstaller: :Install: Cannot find Joomla XML setup file

The reason of this error message is simple: the XML file present uses the <install> tag in the xml file which was deprecated at the end of Joomla 1.5 (although still worked in 2.5) however this function has now been removed from Joomla 3.0, hence it can't find a function that works.

The solution: open the xml file used for installation for editing and modify the <install> tag with the  the <extension> tag. For example, the following code

<?xml version="1.0" encoding="utf-8"?>
<install type="component" version="1.6.0">

... installation code...


will become

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="1.6.0">

... installation code...


Then save the file and repack to a zip archive (the installation package) the extension.

One of the errors triggered by the usage of extensions created for previous Joomla versions looks like this:

Joomla Fatal error: Class classname cannot extend from interface JController

The reason: It looks like the interface JController has been removed, and now you have to specify which controller you're using.

So, the following code

$controller = JController::getInstance('classname');

will become

$controller = JControllerAdmin::getInstance('classname');

Also, there is one thing you should change:

class ClassnameController extends JController

will become


class ClassnameController extends JControllerAdmin

programmer eye No comment. It’s clear there is a difference between normal people see and a programmer sees.

Some of you are familiar with this Wordpress error, it appears from time to time depending of what plugins you have installed. I've met it earlier when I upgraded an Wordpress package to version 3.5 and the plugins on that particular website triggered this error... and locked me out for a few minutes from the administrator section.

The solution  was very simple: I logged in using the ftp, I renamed the plugin directory and I tried to access again the administrator section. Of course, another error appeared: some plugin files were missing. I renamed the plugin directory to the original name and the access was restored.

Usually you can find that directory in your-wordpress-directory/wp-content/plugins/. A lot of people are installing wordpress package in the root of their blog, but that is not a rule, it's just a habit.
