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

'Files' is a much better name than 'Nautilus', IMO.

If you've ever spent some time teaching Linux to a non computer literate person, you come to appreciate sensible does-what-it-says GUI program names and the non-obvious names start to stick out.

And a special curse for all those people who decide to name their programs in part by the language or toolkit that it uses. What on earth are you thinking? Users don't care about your little details, you are just making things awkward for them.

But this sub-thread is about searching for help.

How is a new user supposed to search for help with Files? Including the distro name doesn't help. And if the rename is complete then no-one should be calling it nautilus in the forums either, so knowing that it used to be called something else doesn't help.

Call it something like Nautilus File Manager or Gnome File Manager or Fedora File Manager.

But "files" on its own is a useless name.

I converted the code to compile with Visual Studio and ran it. PaperBack was able to input a text file, create a "BMP", and read it back in. The destination file was the same as the source.

However the BMP files that PaperBack generates are not recognized and cannot be read by other programs. PaperBack can't read BMP files created by other applications.

I didn't try scanning the printed page directly with PaperBack. I used a separate computer to scan the page and create a BMP.

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 Sut…

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.

>a) The key used for (en|de)cryption in version 1.00 provides at most an effective key strength of less than 50 bits (and likely far less, perhaps on the order of 15-25 bits, depending on password quality) instead of the expected 256 bits. Version 1.10 derives the encryption key from the password via key stretching, significantly improving key strength. This change causes a small delay in the encryption step.

>b) PaperBack version 1.0 implements ECB mode symmetric encryption. This mode is subject to a watermark attack and leaks information about the encrypted data. Version 1.00 changes the encryption mode to CBC, which mitigates this attack.

These are classic newb mistakes, and great reasons to not trust any encryption on any product unless it has been vetted by others.

This is a revolution for transporting confidential information through customs :) If it's not electronic they won't even bother checking it!

No, sorry, it's not. That's already trivial: Take a microSD card with your info. Put it together with a couple of tablespoons of oatmeal into a tightly and well wrapped plastic package. Swallow it. Travel. Arrive. Poop. Voila. Also, if you bring big stacks of paper it will often be inspected, since a common way of smuggling currency is putting hundred-dollar bills between the pages of books.

Example of PaperBack's output: https://a248.e.akamai.net/f/574/7105/8d/www.extremetech.com/...

I wonder, why so many alignments (or, why such small blocks)? Is this the most efficient size?

Probably to give the scanning software a way to re-sync and correct for skew, etc.

I think you (unintentionally?) are proving the OP right. Because it's far easier to swallow and poop out a plastic bag with a microSD card in it than it is to put a piece of paper in your carry-on. Plus--wouldn't full-body scanners catch something like this?

It depends on the amount of information you want to transfer, and how likely it is that you'll get a full customs inspection. A single microSD card can hold 512 GB of data; try bringing that in paper format through customs.

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…

Yeah, I think Awesome WM has reached enough users that the specific phrase is now recognized by google. But I remember this was a pain about five years ago.
