Swap is a currency exchange rates library for PHP. It provides a single interface to conveniently work with currency exchange rates and integrates with more than a dozen of different exchange rates providers.
Some of the issues addresses by this library are the binding of the money amount to the currency, and currency conversion operations. If your code needs to deal with multiple currencies, you’ll definitely benefit from this library. But even if you are dealing with a single currency, it’s still pretty handy, making the code more transparent and future proof.
THE University of Nicosia (UNIC) has launched a six week, free and open enrolment online course called “Introduction to Digital Currencies”, aimed at anyone wishing to gain a greater understanding of the fundamentals of bitcoin and digital currency in general.
The MOOC (Massive Open Online Course) is due to start on May 15, with other sessions starting each month thereafter.
Cryptocurrencies are electronic cash, and as such, will be used by electronic agents to exchange value, verify contracts, and track identity and reputation. All of a sudden, the computing resources spent by the Bitcoin miners doesn’t seem wasted – it seems efficient, given that it can be used for congestion control and routing of other network resources.
Cryptocurrencies are an emergent property of the Internet – almost a fifth protocol in the Internet suite. If Satoshi Nakomoto did not exist, it would still be necessary to invent them. Someday, they will be used by the machines in our network, on our desk, in our garage, and in our pocket to exchange value and achieve consensus at blinding speeds, anonymously, and at minimal cost.
