With HCCB (High Capacity Color Barcode) of which an implementation is Microsoft Tag you can get 1.5 MB with 600dpi color on a A4. If you add the best compression techniques (cmix v7) depending on the source material you could get 8 times as much english text, easily fitting the pearls or religion: Tenach, New Testament, Quran, Mahabarata, The Dhamapada, the Atthakavagga and the Parayanavagga, Rhinoceros and Lotus Sutra, The Book of the Dead and the Sri Guru Granth Sahib and explanatory texts and commentary on one single A4. Or you could get 4 minutes of stereo music, Opus@40Kbps or half an hour of speech Opus@6Kbps - (Vinyl LP seems to be more efficient and simpler for that). Or the best 25 classical pieces in MIDI, for example Beethoven Symphony #5 in C minor is a 322 KB midi file (compressed 60 KB). With compressed ABC or Alda notation you could even fit 10 times as much. Or you can just read the ABC and automatically 'hear' the music in your head (is there a similar notation for human movement or dance i wonder...). Even so perhaps a better and more cost effective system is microfilm, here an example of the bible printed on a 2 inch film: http://www.amazon.com/Microform-Bible-Much-Like-First/dp/B00FXHBBOO http://www.amazon.com/Microform-Bible-Much-Like-First/dp/B00... - you don't need a computer, just a lensing system. It has one downside, the blind cannot use this unless you'd make an OCR to TTS or braille display converter on top of it. Or as described in the book Mindhacker you could use Dutton Speedwords/Briefscript word abbreviations preferrable tailored to Esperanto to double the text on the microfilm or on your handwritten A4. https://github.com/leonardoce/bumot https://github.com/leonardoce/bumot

I commend your enumeration of religious and mystic texts.

  Yes I was also impressed. But in making the point, the poster surely went overboard - Mahabarata (I just read about it on Wikipedia) is the "longest poem ever written", ten times as long as the combined Iliad and Odyssey, and at 1.8 million words that is going to be hard to fit into 1.5 megabytes even by itself - unless it is massively redundant I don't see how you can do it. The entropy per word has to be about ~1 byte which is cutting it very, very close. Add in all of the other mentioned texts and commentary and I don't buy it. The mentioned compression (cmix v7) surely won't fit it all http://www.byronknoll.com/cmix.html http://www.byronknoll.com/cmix.html

    And it would also require unicode, so it gets even more harder since you have to go out of ASCII range.

      Yes, it would require unicode if I'd include the native language versions. But in this example I meant the english versions I have for personal use - so it's pure ascii markdown. Except for the greek I don't understand arabic, hebrew, sanskrit, pali or the gurmuki script.

    Yes, I must confess it was an educated guess and I was not precise enough. The Mahabhrata is huge so I use an abridged translation (the one by Ramesh Menon). The complete translated Mahabhrata (by Bibek Debroy) is 12 Mbyte uncompressed. Still it's a challenge to get my pearls of wisdom collection down to 1.5 Mbyte (with either an abridged Mahabharata or the Bhagavad Gita section) even without the commentaries as the combined english plain text files are 1.7 Mbyte compressed - 200 Kbyte to much - (from 11 Mbyte uncompressed ascii with the Mahabharata epos substituted by the Bhagavad Gita). So I went a bit overboard, but I still think it's possible to get there, some redundant lines, tabs, introductions and spaces can still be removed. Perhaps I can remove and include certain texts to conform more to what I personally consider the religious highlights of humanity. Removing the ceremonial descriptions, Revelation, chronicles and battles and including The Tao te Ching, The Upanishads, The Gospel of Thomas or The Veda's or make a more contemporary selection including the dark night of the soul, imitation of christ, Rumi and certain hadiths on the life of Mohammed. 10 Mbytes of ascii should be enough for every spiritual adept (and fit 1 A4 of multicolor matrix barcodes), it for sure fits on a 2M formatted floppy.

Regarding notation for human movement, there's Siteswap (https://en.wikipedia.org/wiki/Siteswap https://en.wikipedia.org/wiki/Siteswap) for juggling :)

I might like to save my most important source code as microfilm. So it would be future-proof. No fancy encoding - just text.

I imagine someone in a post apocalyptic world carrying around a single sheet like this without anyway to replay it but taking solace in knowing it exists somewhere in there.

  Ha, yes i don't think an android phone or e-reader will last very long in a post-apocalyptic world. For a surprisingly slight trade-off in capacity one could opt to carry around a A4 sized microfiche (or 4 stacked microfiches) with 500 pages on it with 10K ascii a page (multi columned) which results in 5 MB uncompressed text. You can add a braille grade 2 or briefscript type compression (which is readable) and get 1-2 extra MB of data, contrast that to all the trouble of getting the 8 MB of data on the same 600dpi surface through multi-colored 2D codes and compression. In this case you just need a good portable magnifying lense. It uses even less power then an e-reader. http://www.rootschat.com/forum/index.php?topic=58324.0 http://www.rootschat.com/forum/index.php?topic=58324.0
