bringing data (blog buggy layout)

What do you do if the location for your workplace does not allow any memory devices such as thumbdrive, portable hdd, sd cards?

Smuggle with paper. A typical A4(1682 × 2378mm) page can print a lot of data. Physically 2 side, but if you add a bit of colors, the dimension increases. An example use of this is at Northe/Northey History Part II

A binary QR code can store Max. 2,953 bytes at 150 modules per inch.

25 by 25 module matrix is 12.5 mm (0.5") square

177 by 177 = 7x 25module=7*12.5mm=87.5mm

1682/87.5=19

2378/87.5=27

subtract printer margin = 17x25modules

data storage at 425modules*2953bytes=1,255,025bytes

1 MB of text on one side.  A very slow sneaker net. But hay, one MB worth of zip text is a lot. 

Add a color dimension to the qr code and see how many layers you can overlay it. 3 more channels via RGB (watched National Treasure?)  or CMY. 

As you noticed, I didnt solve the inital problem of how are you going to bring the software to print the QR code above? via mime in email? writing the software if you are a programmer?

I once came across an article. You can create a debugger using copy con and the alt key and entering a list of alt numbers. After building up the debugger, the author proceed to code the virus via debugger (my memory is bit fuzzy) Not the very first, but nonetheless demostrates the idea example.

haha, I seriously doubt anyone will use the method above. But kind of cool for me to have this insight. Years of tree saving efforts pays off.
