new feature: QR codes

QR code blog entry headeras 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.
