Working with Fedora Linux can cause some problems from time to time, some because of bugs, other because of something you do. Or you don't.

Anyway, when creating websites locally or developing new Joomla components and modules, you may need to have a localhost and a MySql installed locally in order to develop & test the site / extension or to develop the database behind that. I have installed a few days ago the localhost and the MySql and everything was just fine. Then, suddenly, while trying to log in to the database using some software for it I was getting all the time the error "1130 host 'localhost' is not allowed to connect to this MySql server".

The localhost was running, the MySql was active and running, everything seemed fine, but when trying to run `mysql` (with and without password, any password) I was getting errors like connecting to mysql server 'localhost' failed and access denied for user 'root'@'localhost', so commands like mysql -u root -h localhost -p or mysql -u root -h 'any ip address here' -p were out of the questions.

The solution for this was rather simple: reset mysql root password. In order to do that (at least for Fedora Linux - for other operating systems you should locate your my.cnf file) change the /etc/mysql/my.cnf configuration file and add skip-grant-tables:

[mysqld]

skip-grant-tables

Restart service and login with root without password, then change the root password using this:

set password for 'root'@'localhost' = password ('your_new_password');

Remove skip-grant-tables entry from my.cnf and restart mysql.

Note: in case you are logged in with your own Linux account (not root) you may need to log in with the root account if you don't have the rights to change the my.cnf configuration file.

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.

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.

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(document.layers||document.getElementById&&!document.all)
          {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;} 
document.oncontextmenu=newFunction(alert(message);returnfalse)</script>

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.
