Burn To The Brim

**Burn To The Brim** is a highly efficient archiving utility designed to solve the classic subset-sum (bin packing) optimization challenge. It intelligently selects and groups files and directories (documents, high-fidelity media, or raw back-ups) to optimally fill recordable Blu-Rays, USB drives or custom-capacity storage drives. By recursively scanning your designated folders, BTTB matches item sizes to your media capacity, finding a near-perfect selection in milliseconds and an absolute perfect packing configuration in just a few seconds. Burn to the Brim 4.0.0 introduces state-of-the-art machine learning semantic coherence logic to BTTB's classical packing algorithms.

RAWImaging

Forensic (but not only) graphical frontend to work with binary images (RAW) of media in GNU/Linux. These images are universal and can be installed using both standard operating systems and popular forensic software such as Encase, Sleuthkit/Autopsy, etc. in all operating systems). The idea of the project is to implement a fast, convenient and safe making of legal copies and manipulating with images, by means of GNU/Linux, without the need for expensive hardware write lock on the media, it is necessary in the existing solutions under Windows. Also the program can be used as a last chance to rescue data from a dying media by software.
