Design for Hackers: a design book for programmers and developers Design Patterns Quick Reference So every time I am designing something new I find myself either searching Google or opening up a gang of four (GoF) book to aid me. I searched for a bit trying to find a handy-dandy flash card showing class diagrams and purposes for the basic GoF patterns but was unable to locate a good one (for free). So I made my own.If you see any mistakes or improvements please post here and I will update the docs. If you find this useful, please consider making a donation, even if it is just a few dollars. There are multiple formats you can download in: PDF Cards: Get it! Poster: Get it! Page 1: Page 2: Enjoy!
Design Bundles | Free and Premium Design Resources Model View ViewModel MVVM facilitates a clear separation of the development of the graphical user interface (either as markup language or GUI code) from the development of the business logic or back end logic known as the model (also known as the data model to distinguish it from the view model). The view model of MVVM is a value converter[4] meaning that the view model is responsible for exposing the data objects from the model in such a way that those objects are easily managed and consumed. In this respect, the view model is more model than view, and handles most if not all of the view’s display logic (though the demarcation between what functions are handled by which layer is a subject of ongoing discussion[5] and exploration). The view model may also implement a mediator pattern organising access to the backend logic around the set of use cases supported by the view. History[edit] Microsoft MVP Josh Smith reported[6] that A notable Javascript implementation of this pattern is Knockout.js. Timeline[edit]
Design thinking Un article de Wikipédia, l'encyclopédie libre. Le design thinking (littéralement « penser le design »), en français démarche design[1] ou conception créative[2], est une méthode de gestion de l'innovation élaborée à l'université Stanford aux États-Unis dans les années 1980 par Rolf Faste. Cette méthode, qui se veut une synthèse entre pensée analytique et pensée intuitive, relève du design collaboratif, pratique du design qui implique les usagers dans un processus de co-créativité. Trois approches[modifier | modifier le code] Le design thinking comporte plusieurs étapes dont le nombre varie en fonction des auteurs : Approche en cinq étapes selon la d.school[modifier | modifier le code] La d.school[7] de l'université Stanford définit cinq étapes[8] qui s'enchaînent logiquement mais ne doivent pas être prises comme un processus linéaire : on peut et doit faire plusieurs cycles, revenir à l'empathie pendant qu'on prototype, etc.[5].

Presentation Model Represent the state and behavior of the presentation independently of the GUI controls used in the interface Also Known As: Application Model GUIs consist of widgets that contain the state of the GUI screen. Presentation Model pulls the state and behavior of the view out into a model class that is part of the presentation. Presentation Model may interact with several domain objects, but Presentation Model is not a GUI friendly facade to a specific domain object. Presentation Model is known to users of Visual Works Smalltalk as Application Model How it Works The essence of a Presentation Model is of a fully self-contained class that represents all the data and behavior of the UI window, but without any of the controls used to render that UI on the screen. To do this the Presentation Model will have data fields for all the dynamic information of the view.

Code Metrics, Code Smells, and Refactoring in Practice - The Cod Introduction Our team uses eXtreme programming practices to manage development on a mission critical system for a large retail chain. We have not adopted all the practices, but use the majority of the practices. Here is a list of the practices we use: Test-Driven Development (VSTS Testing Tools) Collective Code Ownership Coding Standards (FxCop, Code Metrics) Continuous Integration (daily builds, but we are looking to implement a CI environment soon) Planning Game (iteration planning and daily standup meetings) Customer Test (Fit, VSTS Web Tests) Small Releases (fortnightly UAT releases) Every morning at the standup meeting, the team lead will report on the nightly integration build. This report includes the following metrics: Unit tests passed, failed, ignored Fit test passed, failed, ignored, exceptions Test coverage (should be more than 80%) Cyclomatic complexity (should be less than 10) Code instructions (should be less than a 100) FxCop rule validations Background Here is the method:
