Applications on iOS and macOS are packaged differently from applications on other platform, most notably Windows.
How do banks pay each other? When banks want to transfer money to each other, perhaps upon instruction from a customer, they don’t put bundles of banknotes in a van and drive it off to the recipient. They pay each other digitally. How does this work?

There are four main interbank payment systems in the UK: CHAPS, BACS, Faster Payments and C&CC. These were previously operated under the umbrella of the Association for Payment Clearing Services (APACS). Now run as independent companies.
By default, variables in Rust are immutable. When a variable is immutable, once a value is bound to a name, you can't change that value. These checks are made at compile-time. Variables can be made mutable by adding mut in front of the variable name. Difference between variables and constants Constants are declared using the… Continue reading Rust: Variables and mutability
Rust neither uses garbage collection nor automatic reference counting nor manual memory management. It has chosen a rather different approach: memory is managed through a system of ownership with a set of rules that the compiler checks at compile time.
Rust is a statically typed language so it must know the types of all variables at compile time.
Compared to all the other machines around us, the most unique feature of the digital computer is its amazing versatility. How does a machine with a finite hardware perform seemingly infinite array of tasks, from games to word processing to scientific simulation?
