The Five Most Dangerous Security Myths: Myth #3

by Erik Larkin When the Web was young and blink tags abounded, it wasn’t hard to avoid the bad stuff online. You could generally tell by looking at a site if it was unsavoury or even dangerous, and if you were careful with your surfing and your e-mail, you could generally have gone without antivirus. Not anymore. These days crooks like nothing more than to find a security flaw in a benign but vulnerable site and use the flaw to insert hidden attack code. Once in place, that hidden snippet will scan for security flaws on your PC any...

The Five Most Dangerous Security Myths: Myth #2

by Erik Larkin Sure, the Web is today’s Wild West, with digital guns blazing and no sheriff in sight. But as long as you use a good antivirus program, you’re completely safe, right? Wrong. A good security program will help a good deal, but no program can catch everything. Antivirus companies are locked into a constant battle with the bad guys, who put all their effort into staying one step ahead of antivirus detection with a flood of new techniques and programs. Security software can often deflect those threats. But sometimes, the bad guys get the upper hand. Antivirus...

by Erik Larkin Note: This is the first of five parts. For the next part, click on the link at the bottom. Still think that today’s computer viruses and other malware come from some maladjusted teen out to vandalize your PC to make a name for himself? Think again. The persistent myth is a holdover from days long gone, and it’s important to dispel it if you want to know what you’re up against – and how to protect yourself. The splashy worms and malicious viruses that clogged entire networks and indiscriminately wiped hard drives are essentially gone. Today,...

Committee humour, and yet it is sad…

If your job involves work with a committee, you will appreciate the following two jokes I heard at a conference I recently attended: “A committee is best composed of three people, with one who is always sick and another who is always absent.” “A committee is composed of people who individually can do nothing, who come together to conclude that nothing can be done.” As someone who has spent a career working in and with membership organizations, and with committees, I laughed pretty hard when I heard these wisecracks.  And yet, there is a rather sad truth to the...

Visual Literacy – what is it?


Notice: Undefined offset: 0 in /home/blogs/public_html/wp-content/mu-plugins/avatars.php on line 690

Notice: Undefined offset: 0 in /home/blogs/public_html/wp-content/mu-plugins/avatars.php on line 690
There are many groups of scholars and academics who have attempted to define the concept of Visual Literacy, but as with any group of individuals there is little general consensus so far. This is certainly due to the fact that those representing the different disciplines and archetypes are each wanting to interpret Visual Literacy in a way that reflects and supports their own contribution or way of thinking. The tragic result is that a theoretical concept was created with seemingly little practical value, and cannot be used productively until an agreed definition is established. It should be self-evident that...
