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.
Here’s the semacode for the wikipedia entry on Blogjects (it was the 2nd workshop that Julian and Nicholas have run on those blighters this week, so it seemed an appropriate choice!)
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!
