THE FUTURE of SCREENS from James Stanton a Little Bit About Me
THE FUTURE OF SCREENS From james stanton A little bit about me. Hi I am James (Mckenzie) Stanton Thinker / Designer / Engineer / Director / Executive / Artist / Human / Practitioner / Gardner / Builder / and much more... Born in Essex, United Kingdom and survived a few hair raising moments and learnt digital from the ground up. Ok enough of the pleasantries I have been working in the design field since 1999 from the Falmouth School of Art and onwards to the RCA, and many companies. Ok. less about me and more about what I have seen… Today we are going to cover - SCREENS CONCEPTS - DIGITAL TRANSFORMATION - WHY ASSETS LIBRARIES - CODE LIBRARIES - COST EFFECTIVE SOLUTION FOR IMPLEMENTATION I know, I know, I know. That's all good and well, but what does this all mean to a company like mine? We are about to see a massive change in consumer behavior so let's get ready. DIGITAL TRANSFORMATION AS A USP Getting this correct will change your company forever. DIGITAL TRANSFORMATION USP-01 Digital transformation (DT) – the use of technology to radically improve performance or reach of enterprises – is becoming a hot topic for companies across the globe. VERY DIGITAL CHANGING NOT VERY DIGITAL DIGITAL TRANSFORMATION USP-02 Companies face common pressures from customers, employees and competitors to begin or speed up their digital transformation. However they are transforming at different paces with different results. VERY DIGITAL CHANGING NOT VERY DIGITAL DIGITAL TRANSFORMATION USP-03 Successful digital transformation comes not from implementing new technologies but from transforming your organisation to take advantage of the possibilities that new technologies provide. -

The clients running in the Web browsers traditionally render only pre-computed views fetched from the server. -
Notes - Javascript - Commonjs Modules
Notes - JavaScript - CommonJS Modules Dr Nick Hayward A collection of notes &c. on plain JavaScript modules, in particular usage of CommonJS modules and Node.js. Contents Intro General usage Folders as modules package.json index.js require pattern Dynamic require for modules Module design Intro CommonJS is a module library and pattern popularised by Node.js. It is still in regular use for modern apps, both Node.js and client-side based apps. For client-side, we may use build tools, such as WebPack and Browserify, to bundle module dependencies for online usage in a browser-based environment. General usage In CommonJS, every file is a module. Each module has an implicit local scope, and the global scope needs to be accessed explicitly. The module code is wrapped in a function by the loading call, which provides this local scope. CommonJS modules may export a public interface for consumption in apps - dependencies are resolved using require function calls. require function calls are synchronous, returning the exposed interface for the required module. By default, functions in a module will be local to that module. We may then choose the functions, properties &c. to export in the public API for the module. e.g. // CONSTRUCTOR - create basic keyboard object for testing... function Keyboard(keyDetails) { ({ total: this.total, x: this.x, y: this.y, white: this.white, black: this.black } = keyDetails ); } module.exports = Keyboard; The function Keyboard is now available to other files (modules) by requiring the file, const keyboard = require('./basic1'); Local, relative modules may use the standard Unix path to define file access for the module relative to the application, e.g. -
Restraining Technical Debt When Developing Large-Scale Ajax Applications
WEB 2013 : The First International Conference on Building and Exploring Web Based Environments Restraining technical debt when developing large-scale Ajax applications Yoav Rubin, Shmuel Kallner, Nili Guy, Gal Shachor IBM Research - Haifa Haifa University Campus Haifa, Israel {yoav, kallner, ifergan , shachor}@il.ibm.com Abstract - Addressing technical debt during the software automatic refactoring transformations on code written in a development process relies heavily on a refactoring phase, in dynamic language such as Ruby [10] or JavaScript [11]. which automatic code transformations are used as a crucial Each such tool tried to overcome the lack of type mechanism to reduce a system's technical debt. However, information, which is essential for correct refactoring automatic refactoring is not an option when developing Ajax transformations [5], by using other sources of information. applications. Therefore, an approach that restrains the accumulation of a system's technical debt is needed. In this In the refactoring of Smalltalk codebase, the automatic tool paper, we present and evaluate such an approach and its used a combination of test-cases, results of dynamic reification as a framework. We conclude that our proposed analysis, and method wrappers [6]. Another technique is framework enables restraining technical debt in a large-scale static pointer analysis, which was the vehicle that drove Ajax application without the need for automatic code automatic refactoring in JavaScript codebases [9]. Another refactoring tools. strategy was to rely not only on the analysis of a project's codebase, but rather on additional information provided by Keywords: software engineering; dynamic languages; code the developers, as was done in a Ruby codebase refactoring reuse; technical debt; Ajax mechanism [8]. -

Opinions expressed and conclusions arrived at, are those of the author and are not necessarily to be attributed to the NRF. Abstract The Vula wiki tool is under-utilized in the computer science department at UCT, and in some other departments has been replaced by alternative wiki tools that are easier to use. Since the wiki can be a valuable educational tool, it was decided thatgamificiation should be used to increase the usability of the Vula wiki on mobile phones. This led to the development of a system for computer science undergraduate students which used an iterative user-centered design approach; consisting of a design, implementation and evaluation of a prototype in each stage. Initially, two low-fidelity then two high-fidelity prototypes are developed whilst incorporating user feedback from the previous iteration. At the same time, gamification rules, which are influenced largely by the GameFlow criteria for player enjoyment in games, are refined continually.
