    Easy Beginner's Environment in QT

    Easy Beginner's Environment in QT

    This is a port of the ebe programming environment to QT.

    The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.

    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.
