    ARITA

    ARITA

    Extraordinary audio player for FreeBSD & GNU/Linux

    Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end.

    Bitcoin Black Core

    Bitcoin Black Core

    BLACK use peer-to-peer technology to operate with no central authority

    Bitcoin Black Core is a peer-to-peer electronic cash system that aims to become sound global money with fast payments, micro fees, privacy, and high transaction capacity (big blocks). In the same way that physical money, such as a dollar bill, is handed directly to the person being paid, Bitcoin Black Core payments are sent directly from one person to another. As a permissionless, decentralized cryptocurrency, Bitcoin Black Core requires no trusted third parties and no central bank. Unlike traditional fiat money, Bitcoin Black Core does not depend on monetary middlemen such as banks and payment processors. Transactions cannot be censored by governments or other centralized corporations. Similarly, funds cannot be seized or frozen — because financial third parties have no control over the Bitcoin Black Core network. Bitcoin Black Core combines gold-like scarcity with the spendable nature of cash. With a limited total supply of 10,5 million coins. Transactions are fast.
