I did not know this, do you have a source?

Many projects fall in this trap. I use Awesome as my window manager, and the Awesome theming library is called Beautiful. Now try googling "awesome beautiful wallpaper"...
UPD: http://i.imgur.com/TVLZgqw.png I don't know, how google did it, but the first result for exactly the query of yours is: http://awesome.naquadah.org/wiki/Beautiful What surprises me, is that it works in firefox private mode, where neither of search customizations should work, in theory (fresh clean cookies and local storage, isn't it?). However, yeah, I do indeed google awesome-related stuff from time to time. UP…

Its real name is nautilus
Which is not present in the icon, the menu bar, the about dialog or the help file. http://imgur.com/v4jH7Yf At least they've managed to be consistent with the rename. Compare this to Packages, which is called "packages", or "software", or "software install" or "packagekit". http://imgur.com/dFidCWL
For example the binary for their file archive program is file-roller, but the entry in XDG compatible menus are Archive Manager.
Frankly i find that Freedesktop has been another example of "the road to hell is paved with good intentions". More and more Freedesktop projects reminds me of the kind of Windows stuff i moved to Linux to get away from.
Re: PaperBack – How to store data on a single A4/Letter sheet
#104this has some pretty powerful applications for example for politics or mass dissemination of paper based digital files for the public to quickly consume. Imagine, if students could start posting free textbook pdf files just by handing out a piece of paper which you could scan, or maybe with a phone one day, and instantly receive the file. Why not QR code? QR code needs connectivity while this solution would just requ…
Back then (and i think the law is still in place) anything beyond something like a 90-bit key was considered a military weapon, and thus needed relevant export licenses.
But this only applied to working binaries, not the code printed on paper. So what some researchers did was to get the code printed in a book, using a OCR friendly font, and then ship the book to something like Switzerland where it was scanned, compiled, and put online.

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 b…

#107So I'd like this on medium that's a bit more permanent than paper, but with similar information density per kg, and similar re-creatability without having any of the original tools available. I'd like to store data for say 100 thousand years.
You'll want something that an unsophisticated civilization can make copies of. Might be interesting to have a stylized form of a modern language with layout that incorporates simple integrity checks. The monks who copied documents in the middle ages made a lot of errors.
Not sure whether "stamp" is the right word. I'm talking about this: http://www.stempel-wolf.de/de/img/stempel/herstellung/gravur...

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