A while back I had an idle wish for a firefox extension that autogenerated a 2d barcode (semacode or other) from the URL of the current page/thing/resource, so I could quickly snarf it into my mobile and take it with me.
Instantly-mobile deeplinky goodness with no fiddly typing.*
A random thought tonight while staring at my browser: how much info could I store in a favicon, if I made it a 2d barcode?
A favicon is 16×16, and readable datamatrix 2d codes go down to 10×10 and 3mm. Of course, readable here means by an industrial scanner from a crisp printed sticker, rather than a mobile phone and a fuzzy LCD display.
As you can see, a fair slice of the data is cropped if we try for 16×16 in order to make a favicon.
Still – I wonder if there’s anything doable there? Could something useful and/or diverting be done in this little space in the address field?
If not, my original lazyweb wish for a firefox extension to create instant takeaway datashadows still stands…
* Yes, before Charlie gets all-up-in-my-face (;-) – I know winksite has semacode integration – but I want EVERYTHING I visit to have a code ,whether they like it or not!
