The Interpreter design pattern allows us to implement a simple language to use inside an application. In this article we look at a design example of the interpreter pattern.
The Proxy design pattern is a structural pattern. IA proxy is a stand-in for something else. The Proxy pattern provides a surrogate placeholder for another object to control access to it.
The Mediator pattern is a design pattern that encourages loose coupling between objects. The Mediator pattern keeps objects from referring to each other explicitly, by having a central class that handles the interactions between the other objects.
Android: An automaton in the form of a human being. The science fiction of yesterday is often the science of tomorrow. I don’t think robots will take over the world and wipe out humans any time soon. But many jobs are being affected or even replaced by automation. The past
The command design pattern is a proven solution to the problem of tightly coupled invokers and receivers. The command pattern is a way to encapsulate a request as an object, so that you can parameterize clients with different requests.
Ennui: a feeling of utter weariness and discontent resulting from lack of interest; boredom. I remember when Black Friday was not an event in South Africa. After all the Black Friday emails I received this week, I’m confused.
The Bridge pattern separates the abstraction from the implementation, so that each can vary independently of the other. This allows us to change the classes in each hierarchy independently of the other classes. The bridge design pattern helps to reduce the risk of breaking any existing code.
Queuer: a person who waits in a queue. I didn’t know there was a word for a person who waits in a queue. But this is part of our new normal: longer queues. Especially at government offices. Last week I had to queue at the Tshwane Municipal offices. It was
The Chain of Responsibility pattern is a behavioural design pattern that is commonly used. This pattern decouples classes by passing a request from one class to another until the request is recognised. The receiving objects are chained, and the request is passed along the chain until a specific object handles it. Each object in the chain is given a chance to handle the request.
Computer rage: negative psychological response towards a computer due to anger or frustration. In April 2015, a Colorado man was cited for firing a gun in a residential area. Why? He shot his computer eight times with a pistol. We’ve all experienced that frustration. Hardware failure is very stressful. But
