"...divides a single image into many different images, then compresses them separately." Wouldn't it be better to go the other way and backpack-algo the pages into a consolidated texture atlas based on edge similarity, and then run compression on the result?


From what I understand, it segments the image into text and a background image, does something like JBIG2 on the text (building a global dictionary of glyphs and placing them on the page), and does a lossy compression on the background image.

There aren't a lot of viewers out there for DjVu and the encoding side is patent encumbered, so I'm not interested in the format.

You can get pretty close with JBIG2+Jpeg2k in a PDF file, I believe archive.org does this, but I don't know of an open source encoder that does it and sometimes PDF viewers don't decode jbig2/jpg2k efficiently.


I'm surprised I haven't seen Fuchsia mentioned... anywhere. https://en.wikipedia.org/wiki/Google_Fuchsia


Do any melodic/rhythmic transmission protocols exist?


If you count 10MHz and up as rhythmic then yes! But kidding aside it would be really nice to have a musically encoded version of TCP/IP that sounds nice to the ear.

You could start by picking a major key and then dividing up all bytes to be transmitted into groups of three bits (have fun with the shifting...), that way all 8 tones get to be played, and since it will be monotone it should not sound too bad. Major points if you can do this with chords that sound harmonious.


Combining Zipf distribution, Levenshtein distance, and chords/scales -- might lead to something accommodating with aesthetic qualities.


Olivia sounds kind of nice. See the audio samples on wikipedia.

Beautiful. That sounds like alien birdsong.


Research connected to cellular metabolism seems to be gaining momentum, I recall something on high levels of folic acid [1] not too long ago.

It'll be interesting how the energy landscape gets defined in the near future. Of note, there's a funded kickstarter that stores energy in residential flywheels that appears to be another promising solution: http://www.kickstarter.com/projects/1340066560/velkess-energ...


With all these companies listed I'm surprised Willow Garage didn't join up with Google; given that the founder was a googler.


In effect, they did. Willow Garage was restructured into Redwood Robotics. Google purchased Redwood Robotics. There are certainly lots of messy details, but the key projects (ROS & OpenCV) and the engineers from Willow Garage are now at Google.


I count five failed attempts within two days (190.39.254.6, 201.209.39.192, 85.152.192.118 ,186.88.197.41, 190.200.20.207). Good to know the password -that I almost manage to forget- is strong enough.
