Researchers at Lab42 wanted to know “what makes certain codes so scanworthy,” so they conducted an online survey via social networks of 500 Americans over 18, and found out that many people don’t even know what a QR code is.

“popurls is the dashboard for the latest web-buzz, a single page that encapsulates up-to-the-minute headlines from the most popular sites on the internet.”

I love it. popurls is now my start page. The basic idea is that it is a single page RSS feed aggregator. It provides a single page mashup to see what the hive mind has is paying attention to. With a glance, you can see the top stories in Digg.com, del.icio.us, reddit.com, flickr.com, youtube,…

Very cool.

Apparently getting USTREAM.TV to work on a MacBook Pro is easy, but not so for a MacBook. Not sure why there is a difference, but this is what I had to do.

First off, I’m using Firefox on my Black MacBook. There are some users reporting that USTREAM is not happy with Safari. I haven’t validated this, so YMMV.

USTREAM uses Adobe Flash Player as the basis for connectivity. So to get it to work, you have to access some control panels that I didn’t even know existed.

The tips that seems to get things working are:

- Go to Adobe Flash Player Settings Manager – Website Privacy Settings Panel
and delete all the websites from the list.
- When you try to connect, another window will open that will say connecting. Right-click/Ctrl-Click to get to “Settings”. There, you’ll have to click on the webcam icon and set the camera type to “USB Video Class Video.”

That should do it. Let me know if it works for you. Have fun!
