     -   This creates natural boundaries between different code blocks, enforcing proper interfaces, and easing independent development to be conducted on various code parts at the same time, without the fear of running into conflicts.

I didn't find a way to turn that off (setting ptys to raw mode didn't change anything) and it's not mentioned anywhere on the Internet, so maybe it's something on my system.

 **Project**: Qubes Converters
 
-**Brief explanation**: One of the pioneering ideas of Qubes is to use disposable virtual machines to convert untrustworthy files (such as documents given to journalists by unknown and potentially malicious whistleblowers) into trustworthy files.  See [Joanna's blog on the Qubes PDF Convert](http://theinvisiblethings.blogspot.co.uk/2013/02/converting-untrusted-pdfs-into-trusted.html) for details of the idea.  Joanna has implemented a prototype for PDF documents.  The goal of this project would be to generalize beyond the simple prototype to accommodate a wide variety of file formats, including Word documents, audio files, video files, spreadsheets, and so on.  The converters should prioritise safety over faithful conversion.  For example the Qubes PDF converter typically leads to lower quality PDFs (e.g. cut and paste is no longer possible), because this makes the conversion process safer.

 **Expected results**: We expect that in the timeframe, it will be possible to implement many converters for many file formats.  However, if any unexpected difficulties arise, we would prioritise a small number of safe and high quality converters over a large number of unsafe or unuseful converters.
