I’m going to take a slight departure from my normal free stuff on Friday posts.

Don’t worry, this is still free, but it’s not just a “click here and look at this thing” kind of post.  This week, you’ll need to actually do a couple of things to get the full benefit of this post.  Basically, it’s a little Summer DIY project for the mildly geeky and social.

Have you ever been to someone’s home and had to ask for their WIFI…

Do you trust everything you see?

We’ve all seen QR codes, even if we may not have all recognized what they are.  These little, square dot patterns are everywhere these days, especially in advertising.  In fact, some people have gotten so used to scanning them with their smart phones to get more information about products and services that hackers are now exploiting them.  I recently read a very interesting article on TechRepublic by Michael Kassner titled Beware of QR Codes about an exploit found in the wild, and QR code exploits in general.  The problem is, we tend to trust them, mainly, I think, because they’re too new for us to have been burned bad by them yet, and they are popping up everywhere!  Pay attention as you go through your day and see how many of these little deals you bump into.  They’re in everything from magazine ads to product labels to posters to coupons!  Even Doonesbury has run a strip with a QR code in it!

So, as you swim out there, awash in the ocean of marketing and sales that we live in, pay attention to those who might subvert your complacency.  If it’s easy for you to use, it’s probably easy for someone to abuse, just like the QR code seems to be!

I guess QR codes aren’t quite dead yet!

Back in the day, hobos, or “gentlemen of the rails”, used to use a kind of code that let other hobos know important information.  For instance, if they marked a cat-like symbol on a fence, it meant that a kind-hearted woman lived at that house and might give a hungry drifter food.  Or, three diagonal lines means that the place is unsafe and a hobo should get out of there as quickly as they can.  (You can see more codes on Wikipedia.)
Well, someone has updated that for the modern world and smart phones.  That’s right, someone has made QR Code Hobo Codes.  Now, you can just print up templates and spray them with paint out there in the world and people can shoot them with their iPhone, or Droid, or whatever, and see the information.  And the codes have been updated for modern life, too!  Now, they’ve added things like “bad coffee”, “dangerous homophobes”, “camera perverts”, “no outlets”, and “insecure wifi”, among others.

So, who knew?!
Now, while you’re out adventuring this weekend, keep an eye out for QR codes to scan!  You may find some interesting things along your way!
Have a great Friday and enjoy your weekend!
