Sometimes you need to scan a QRCode while sitting at your desktop computer and you do not want to pull out your phone to do it. You could take a screenshot and upload it to a website to let it decode, but no, why not using a simple webapplication to scan it?

I wrote an JavaFX application today.

Simply click HERE, accept the signature, move the window above the code (and adjust the size), press Enter you will get the result!

It is simple, but powerful. More features and better usability can be discussed. You can also save the application on your drive for later use.

Requirements for Windows: Java 6 Update 10. Works with latest Java Update on MacOSX. Get the latest Java for your browser. This application takes advantage of the javaFX transparent window feature. Decoding is powered by zxing.

I got the chance to collect some data from the playlists of some of the radio stations, which belong to the public northern German broadcasting, NDR. I created some tables, where you can see, which songs and artists where played most in the last 100 days. I am sure, the NDR has his own statistics, but I’ve never seen them in public. That is why I am showing a little view at it here.

After I decoded a lot of QR Code images, it was an easy step to download Data Matrix Code images and find out, what kind of content people encode in these. For those, who are interested, for the decoding, I used the libdmtx library. As a backup, I used other libraries to check, if the code was really a Data Matrix or if the content of the image contained other types of codes. Therefore in some cases, I found QRcodes and 1D Barcodes, which is effected by the results of the image search engines.

IPhone users and application logo designers, here is the iPhone App alphabet. When I saw all the logos with just the letters inside, I thought, I should look for fun, if there is a complete alphabet.

And it is not complete! The V and the O are missing or I just didn’t find them. Have a look at this little collection of logos and enjoy. For an interactive version of the alphabet, please visit this link.

I recently decoded a lot of images containing a QR Code finding them using image search engines like Google, Yahoo or Flickr. Please see the QR code webimage analysis for the results.
