Creational patterns were first described in the famous Gang of Four’s Design Patterns. The book presents each pattern in a dedicated chapter and follows a strict structure for each one: intent, motivation, applicability, structure, participants, collaborations, consequences, implementation, sample codes, known uses, and related patterns. The intent pattern presents a succinct goal of the pattern, while the applicability tells when you should use it. For example, here’s an excerpt fo| A Java geek
The Prototype Design Pattern is a creational pattern that lets us create new objects by cloning existing ones instead of instantiating them from scratch.| amritpandey.io

A Python dictionary has a simple & well-known API. It is possible to merge data using a nice & minimalistic syntax, without mutating or worrying about state. You're probably not gonna need classes.| Agile & Coding
The Singleton pattern is one of the quirkiest and most trivial patterns in existence. This pattern was created to fulfil the need for a single, one-time instantiation of an object that is shared among multiple components.| amritpandey.io
B+Trees are one the most common structures in the database world, especially in a context of indexing. They map well onto a page/block model used for persisting data on the hard drives and provide a nice "jack of all trades" route between capabilities (eg. sorting, range| Bartosz Sypytkowski

After my last post and generally the kind of indirect advertising I’m doing to the Go programming language for a few months now, I heard about and talked with a lot of people who started being interested in the language, so for once I decided to write what I don’t like about it instead, to provide a more balanced perspective of what’s my experience so far and maybe let some of those people realize that Go is not the right choice for their projects after all. NOTE 1 It’s important to s...| evilsocket
How can we make disabled buttons more inclusive? When do they work well, and when do they fail on us? And finally, when do we actually need them, and how can we avoid them? In this article, Vitaly Friedman will take a look to common usability issues with disabled buttons, how to fix these issues and when disabling buttons actually makes sense. We’ll start from the beginning, looking into when disabled buttons cause more trouble than help.| Smashing Magazine
Dynamic polymorphism (virtual functions) is central to Object-Oriented Programming (OOP). Used well, it provides hooks into an existing codebase where new functionality and behaviour can (relatively) easily be integrated into a proven, tested codebase. Subtype inheritance can bring significant benefits, including easier integration, reduced regression test time and improved maintenance. However, using virtual functions in C++ brings a runtime performance overhead. This overhead may appear inc...| Sticky Bits - Powered by Feabhas
