Model–view–controller

Model–view–controller
Model–view–controller (MVC) is a software pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.[1][2] The central component, the model, consists of application data, business rules, logic and functions. A view can be any output representation of information, such as a chart or a diagram. Component interactions[edit] A typical collaboration of the MVC components In addition to dividing the application into three kinds of components, the Model–view–controller (MVC) design defines the interactions between them.[4] Use in web applications[edit] Although originally developed for desktop computing, model-view-controller has been widely adopted as an architecture for World Wide Web applications in all major programming languages.

VPython Design Then Code: Building iOS Apps From Scratch Before taking a crack at any Design Then Code project tutorials you'll need some knowledge of Xcode, Objective-C, Cocoa and UIKit. My goal is for this guide to help bridge the gap between having no knowledge of iOS development and having enough to start tackling more interesting projects. Tools Apple provides a number of tools to enable developers to build Mac and iOS apps. To download them, head to the Mac App Store and search for "Xcode". Here's a quick overview of the tools Apple provides. Xcode Xcode is an IDE (Integrated Development Environment) used by Mac and iOS developers to build applications. Interface Builder Interface Builder is an application that lets you build your interfaces visually. In my particular development workflow, I prefer not to use Interface Builder, mostly because I work on custom interface components and those still take a lot of code to get exactly right. Frameworks And the most important piece of the puzzle: frameworks. Introduction To Programming? @end

Don't repeat yourself Applying DRY[edit] DRY vs WET solutions[edit] Violations of DRY are typically referred to as WET solutions, which is commonly taken to stand for either "write everything twice" or "we enjoy typing".[2][3] See also[edit] References[edit] External links[edit] Python programming - creating PyQt4 gui applications, language introduction tutorials Interesting Articles IronPython introduction for Python developers - A quick look at IronPython for Python / Linux developersScripting Ximea machine vision cameras in IronPython - Imaging with Ximea cameras using IronPython scriptsWorking with virtualenvs using virtualenvwrapper - How to manage and use multiple virtualenv instances using virtualenvwrapperTokyo Cabinet and Python - Tokyo Cabinet is a scalable key-value database that can be used in high performance applications, including Python.Using MongoDB in Python and PHP - MongoDB is a no-relational document database.

Advanced Memory Management Programming Guide: About Memory Management Application memory management is the process of allocating memory during your program’s runtime, using it, and freeing it when you are done with it. A well-written program uses as little memory as possible. In Objective-C, it can also be seen as a way of distributing ownership of limited memory resources among many pieces of data and code. When you have finished working through this guide, you will have the knowledge you need to manage your application’s memory by explicitly managing the life cycle of objects and freeing them when they are no longer needed. Although memory management is typically considered at the level of an individual object, your goal is actually to manage object graphs. Objective-C provides two methods of application memory management. In the method described in this guide, referred to as “manual retain-release” or MRR, you explicitly manage memory by keeping track of objects you own. Good Practices Prevent Memory-Related Problems See Memory Management Policy.

Convention over configuration Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “sale”, that one needs to write code regarding these names. When the convention implemented by the tool matches the desired behavior, it behaves as expected without having to write configuration files. Only when the desired behavior deviates from the implemented convention is explicit configuration required. Motivation[edit] Some frameworks need multiple configuration files, each with many settings. Usage[edit] See also[edit] References[edit] External links[edit]

Active record pattern This pattern is commonly used by object persistence tools, and in object-relational mapping (ORM). Typically, foreign key relationships will be exposed as an object instance of the appropriate type via a property. Implementations[edit] Implementations of the concept can be found in various frameworks for many programming environments. For example, if in a database there is a table parts with columns name (string type) and price (number type), and the Active Record pattern is implemented in the class Part, the pseudo-code part = new Part() part.name = "Sample part" part.price = 123.45 part.save() will create a new row in the parts table with the given values, and is roughly equivalent to the SQL command INSERT INTO parts (name, price) VALUES ('Sample part', 123.45); Conversely, the class can be used to query the database: b = Part.find_first("name", "gearbox") This will find a new Part object based on the first matching row from the parts table whose name column has the value "gearbox".

pyFLTK Home Page A Checklist for Content Work In content strategy, there is no playbook of generic strategies you can pick from to assemble a plan for your client or project. Instead, our discipline rests on a series of core principles about what makes content effective—what makes it work, what makes it good. Content may need to have other qualities to work within a particular project, but this list is limited to qualities shared across all sorts of content. If this looks like theory, don’t be fooled. It’s really entirely practical: if we consciously refer to principles like these as we go about our work as info-nerds of various kinds, we’ll have an easier time making good, useful content, and explaining our priorities when we’re called to do so. Good content is appropriate#section1 Publish content that is right for the user and for the business There’s really only one central principle of good content: it should be appropriate for your business, for your users, and for its context. Right for the user (and context)#section2 Fig. 1.

What is CGI and How To Use Your CGI-BIN CGI Tutorial and Perl Introduction for Beginners A lot of people have Web pages but most feel that CGI scripts are "over their head". Nonsense! If you know basic HTML and know how to use an FTP program like WS_FTP to transfer files, chances are you can be using a CGI script on your Web pages in about 15 minutes. With so many free CGI scripts available (including Bestdam Logger Lite) you are really short-changing yourself if you are not using the CGI capabilities offered by your ISP or host provider to use CGI scripts. While there are a lot of "CGI Tutorial" pages out there, most deal with how to write CGI scripts. * Note: Java is not a scripting language. Even though the script code for PHP, ColdFusion, and ASP is embedded in the HTML code, it's not visible at the browser (when using View/Source). 1. If the answer to both of these questions is "Yes", you're good to go. "Server-Side Includes" are just that, commands (aka "directives") to the Web server to include some information the server has in the displayed Web page. Top of page
