At launch, Java was the only officially supported programming language for building distributable third-party Android software. Android Native Development Kit (Android NDK) which will allow developers to build Android software components with C and C++. In addition to delivering support for native code, Google is also extending Android to support popular dynamic scripting languages. Earlier … Read more
Some of the basic data structures in programming languages such as C and C++ are stacks and queues. The stack data structure follows the “First In Last Out” policy (FILO) where the first element inserted or “pushed” into a stack is the last element that is removed or “popped” from the stack. Similarly, a queue … Read more
It doesn’t mean anything. It is rather a common naming convention for private member variables to keep them separated from methods and public properties. For example: class Foo { private int _counter; public int GetCounter() { return _counter; } public int SetCounter(int counter) { _counter = counter; } }
Since you say “embedded system” and “small and fast” and “integrate nicely” I would say you are correct that Lua is the number one if not the only choice. But I no longer agree that the programming language has “quirky corners”. Firstly, the book Programming in Lua is simply splendid, one of the best books … Read more
Watch this lecture. The idea is that your program is a combination of a datatype and operations over it. The problem asks for an implementation that allows to add new cases of the type and new operations without the need for recompilation of the old modules and keeping static type safety(no casts or runtime type … Read more
Myth: That Scala’s “Option” and Haskell’s “Maybe” types won’t save you from null. 🙂 Debunked: Why Scala’s “Option” and Haskell’s “Maybe” types will save you from null by James Iry.
There is a programming language called Inform that, in its most recent incarnation, Inform 7, looks a lot like natural language…in particular, written language. Inform is very specifically for creating text adventure games, but there is no inherent reason that the concepts couldn’t be extended into other realms. Here’s a small snippet of Inform 7 … Read more
Static Typing Static typing means that types are known and checked for correctness before running your program. This is often done by the language’s compiler. For example, the following Java method would cause a compile-error, before you run your program: public void foo() { int x = 5; boolean b = x; } Dynamic Typing … Read more
You can do it like this: class Example { private $__readOnly = ‘hello world’; function __get($name) { if($name === ‘readOnly’) return $this->__readOnly; user_error(“Invalid property: ” . __CLASS__ . “->$name”); } function __set($name, $value) { user_error(“Can’t set property: ” . __CLASS__ . “->$name”); } } Only use this when you really need it – it is … Read more
I’m glad you’re starting by asking about a specification rather than implementation first. There are a lot of ideas floating around about what FRP is. From the very start in the early 90’s (when I was working in interactive graphics at Sun Microsystems and then Microsoft Research), it has been about two properties (a) denotative … Read more
