as you may have noticed, i’ve added QR codes to this blog. QR codes (which stands for “Quick Response codes”) are 2D bar codes that can be scanned and decoded using a mobile phone — [i’ve written about them earlier over on my professional blog][xyzzy-qr]. by clicking on the “QR code for this entry” link in the header of each blog entry you’ll get an overlay featuring the QR code for that blog entry — which you can then scan and bookmark using the camera of your mobile phone (provided you have one of the QR code readers[^1] installed or a pre-installed one on your phone)

[^1]: newer nokia phones have the bar code reader application, but you can also install a reader from sites such as: [kaywa](http://reader.kaywa.com/) and others.
