Lesson 10 Design Pattern and Universal Design

Design Pattern and Universal Design

Design Patter are used by programmer by re-using a pattern to create a solution in a problem, notably in software engineering. It is formalized as the best practices that programmer can use to solve common problems when designing an application to minimize the errors.  These solutions were obtained by trial and error by numerous software developers over quite a substantial period of time.

Universal design is the process of creating products that are accessible to people with a wide range of abilities, disabilities, and other characteristics. In creating a universal design the programmer should be aware that it must be a usable, accessible and inclusive to the users.

usable - design that are usable to all the user without the need for adaptation or specialized design

accessible - design that are accessible to the needs of the people with disabilities that are specifically considered. 

inclusive - is about engaging authentically with the diverse people that make up markets and audiences, not just about providing usable accommodations or catering to specific needs.

despite of our differences regardless age, gender, culture, environment, size, health and etc. universal design are applied in all application by programmers to be equitable use, flexible in use, simple and intuitive, perceptible information, tolerance for error, low physical effort, size and space for approach and use for all the users.

Lesson 7 Web Application Design and Development

 The lesson 7 topic was all about Software Deployment.   Software deployment includes all of the steps, processes, and activities that are required to make a software system or update available to its intended users. Today, most IT organizations and software developers deploy software updates, patches and new applications with a combination of manual and automated processes. Some of the most common activities of software deployment include software release, installation, testing, deployment, and performance monitoring. Software deployment vs Software release So basically a  release  is a polished, tested version that is published, typically  with a  version number one greater than the last  release . To  deploy  means to push a new  release  to one or more machines, updating the current version. In web development, this means updating the version hosted on the production servers. note: even though a new version is release their...

Lesson 9 Javascript

  The lesson 9 topic was all about JavaScript contained 2 parts of the video. The first part was focused on knowing what is JavaScript.

JavaScript Commands - JavaScript code gives instructions to the  web browser . -JavaScript  commands  are usually called  JavaScript code . -Each command should end with a  semicolon . It helps your code be more readable to you and the browser, too. Most programming languages give commands to the computer. However, JavaScript commands the web browser.  Usually, programs contain many statements, which give instructions to the browser. In JavaScript programs,...

Lesson 6 Mobile Application Design and Development

 The lesson 6 topic was all about Mobile Application Design and Development.   Mobile technologies have transformed the way we live, work, learn, travel, shop, and stay connected. Not even the industrial revolution created such a swift and radical explosion in technological innovation and economic growth worldwide. Nearly all fundamental human pursuits have been touched, if not revolutionized, by mobile.  In June 29, 2007 the iPhone went sale and became fundamentally change the way people interact with phone because of it's interactive OS and design that are very convenient to the user. Then the raise of tablets became popular too because of it's larger screen but it comes with a drawback since tablet are way larger than smartphone, it also very uncomfortable sometimes for example: it can't fit on a pocket that it needed a bag to be able to carry it outside.
