A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander and has been adapted for various other disciplines, most notably computer science.
An organized collection of design patterns that relate to a particular field is called a pattern language. This language gives a common terminology for discussing the situations designers are faced with.
Documenting a pattern requires explaining why a particular situation causes problems, and how the components of the pattern relate to each other to give the solution.Christopher Alexander describes common design problems as arising from "conflicting forces" — such as the conflict between wanting a room to be sunny and wanting it not to overheat on summer afternoons. A pattern would not tell the designer how many windows to put in the room; instead, it would propose a set of values to guide the designer toward a decision that is best for their particular application. Alexander, for example, suggests that enough windows should be included to direct light all around the room. He considers this a good solution because he believes it increases the enjoyment of the room by its occupants. Other authors might come to different conclusions, if they place higher value on heating costs, or material costs. These values, used by the pattern's author to determine which solution is "best", must also be documented within the pattern.
Pattern in architecture is the idea of capturing architectural design ideas as archetypal and reusable descriptions. The term "pattern" in this context is usually attributed to Christopher Alexander, an Austrian born Americanarchitect. The patterns serve as an aid to design cities and buildings. The concept of having collections of "patterns", or typical samples as such, is much older. One can think of these collections as forming a pattern language, whereas the elements of this language may be combined, governed by certain rules.
Alexander's idea of patterns
Alexander's patterns seek to provide a source of proven ideas for individuals and communities to use in constructing their living and working environment. As such their aim is both aesthetic and political: to show how beautiful, comfortable and flexible built environments can be constructed, and to enable those people who will inhabit those environments to challenge any solution forced upon them.
A pattern records the design decisions taken by many builders in many places over many years in order to resolve a particular problem. Alexander describes a problem in terms of the so-called forces that act in it, and the solution is said to resolve those forces. If there are still unresolved forces, then additional patterns may be needed to balance these remaining forces.
In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. A design pattern is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations. Patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved. Patterns that imply mutable state may be unsuited for functional programming languages, some patterns can be rendered unnecessary in languages that have built-in support for solving the problem they are trying to solve, and object-oriented patterns are not necessarily suitable for non-object-oriented languages.
In September 2014, Portland, Oregon-based Top Level Design (TLD) won the right to operate the .design top-level domain after beating out six other applicants in a private auction. According to TLD's CEO Ray King, winning the auction was "very important" and one of the company's top priorities, evidenced by its name. He told Domain Name Wire, "Think of all the things that require design. Design permeates all aspects of culture.". design domain registrations became available to the general public on May 12, 2015. According to The Domains, more than 5,200 .design domains were registered on the first day of general availability.
CentralNic provides backend services through an exclusive distribution agreement and shares in the global revenues from .design domain names. Ben Crawford, CentralNic's CEO, said of the top-level domain, "It has impressive commercial potential, and it will be adopted more quickly than many other TLDs as it caters, among many other groups, to one of the best-informed professions on new Internet developments – website designers".
Thus "design" may be a substantive referring to a categorical abstraction of a created thing or things (the design of something), or a verb for the process of creation, as is made clear by grammatical context.
After a recommendation from high-ranking Dutch naval officers that the Koninklijke Marine (Royal Netherlands Navy) be bolstered so any attacker would have to "use such a large part of his military potential that there would be an unacceptable weakening of his capabilities in other theaters", the Minister of Defense ordered the Navy to prepare designs for a two or three-member class of battlecruisers. As they had not previously designed a modern capitalship, and the only information available on modern designs came from public literature and editions of Jane's Fighting Ships, the Dutch turned to Germany. This initially bore no results, as the two sides were unable to come to terms. During this time, a preliminary plan was drawn up without foreign assistance; completed on 11 July 1939, it was missing many of the post-First World War advances in warship technology. In particular, the armor protection was totally outmoded.
An adapter or adaptor is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one electrical connector to another.
An electric power adapter may enable connection of a power plug, sometimes called «travel plug», used in one region to a AC power socket used in another, by offering connections for the disparate contact arrangements, while not changing the voltage. An AC adapter, also called a "recharger", is a small power supply that changes household electric current from distribution voltage (in the range 100 to 240 voltsAC) to low voltage DC suitable for consumer electronics.
For computers and related items, one kind of serial port adapter enables connections between 25-contact and nine-contact connectors, but does not affect electrical power- and signalling-related attributes.

Design patterns allow us to use tested ways for solving problems but there are 23 of them in total and it can be difficult to know which ones to pay attention to. In this video I cover what exactly design patterns are and the top 5 that I have used the most in my career.

A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander and has been adapted for various other disciplines, most notably computer science.
An organized collection of design patterns that relate to a particular field is called a pattern language. This language gives a common terminology for discussing the situations designers are faced with.
Documenting a pattern requires explaining why a particular situation causes problems, and how the components of the pattern relate to each other to give the solution.Christopher Alexander describes common design problems as arising from "conflicting forces" — such as the conflict between wanting a room to be sunny and wanting it not to overheat on summer afternoons. A pattern would not tell the designer how many windows to put in the room; instead, it would propose a set of values to guide the designer toward a decision that is best for their particular application. Alexander, for example, suggests that enough windows should be included to direct light all around the room. He considers this a good solution because he believes it increases the enjoyment of the room by its occupants. Other authors might come to different conclusions, if they place higher value on heating costs, or material costs. These values, used by the pattern's author to determine which solution is "best", must also be documented within the pattern.
