For some time I've watched as New Zealand businesses have been seduced by the so called advantages of Cloud Computing.
In a manner similar to drug pushers, they dole out free "hits", they eschew free services that entice business owners to send their IT provisioning to places unknown overseas. The glamour of the websites, extolling these services, appears to induce a feeling of security, all the while containing many a fish hook.

 In this article I will look at the new ways in which Moodle 2.0 handles files and resources.
Moodle Resources
In Moodle "Resources" are the documents and files we use to present information, or content for our Courses. They may be text, graphics, or multi-media.

When selecting a resource in Moodle 1.*
we had the following options

In Moodle 2.0 this is now updated to:

Moodle 2.0 was recently released, and I'll try here to give some idea of what the transition from the Moodle 1.* releases to Moodle 2.0 will mean to everyone.
Now there will be different effects depending upon whether you are a student, a teacher, administrator, or developer. I'll try and keep it simple.
Major System Rewrite
Moodle 2.0 is a major rewrite of the base Moodle software, with changes to the Themes, Modules & Blocks, and consequently all areas of functionality.
This means that the themes that worked for version 1.* may most probably not work for version 2.0. So one of the major effects will be the need to rewrite any custom themes that have been created.
However, the theme upgrade has given Moodle a much more cleaner look, and a faster execution. So well worth the move.

 An article on the BBC recently called for people to use stronger passwords in the wake of more computational power available to hackers. We know that security needs to scale as computers become more powerful because security is ultimately a numbers game. A hacker needs to guess the correct numbers to get to the encrypted data and security is all about the amount of time he will likely need to guess those numbers.
This article by Emmanuel Carabott explains the current state of play for hacking passwords.

Moodle Moment -Changing Domain Name |

 I often come across issues with Moodle when changing domain names. This happens when placing Moodle in a staging environment with a temporary domain name, and then moving it into production.
The problem is that Moodle by default loads images with an absolute URL. An absolute URL specifies the whole URL ... ie http://www.mydomain.com/moodle/myimage.jpg.
A better method would be to use a relative URL. This would just use the location of the file on your server ( in the example above, /moodle/myimage.jpg), and leave the browser to remember which server using the current domain. But this has to be done manually for each image loaded.
To solve this issue, there is a useful script that has been written by the Moodle gurus, and available for use by a user with administrator rights.
http://www.mydomain/admin/replace.php
Replace the www.mydomain with your own site address, and then fill in the details asked, and all is sorted in an instant, or two.

Rushing Too Fast to Online Learning? |

Science Daily reports on a new study released by the National Bureau of Economic Research (NBER) raises questions about that fast-growing trend in higher education.
 The study's strongest findings in favor of live instruction were for relatively low achieving students, male students and Hispanic students. While they may be better served by face-to-face education delivery, often those are the students who are most likely to receive online education.
You can read the original article here.
This article resonates with my own experience that lower achieving students need the personal hands on approach to give them the inspiration and support to make it through the course. This is a plug for blended learning which combines the value of study online and face to face interaction.
