The paper will give an example and an overview of how we can set up and maintain web applications using a Docker. We will define what Docker is, what containers are and how to use them. Developers often find themselves in a situation where their program works properly on a computer in the laboratory environment in which the application was developed, but after installing the program on the production server, the program does not work as expected. In such circumstances, it is difficult for a programmer to determine why a program is not working. Docker solves this problem by placing applications and virtual containers that run on the same operating system.

One example of the growing information technology today is mobile learning, mobile learning which refers to mobile technology as a learning medium. Mobile learning is learning that is unique for each student to access learning materials anywhere, anytime. Mobile learning is suitable as a model of learning for the students to make it easier to get an understanding of a given subject, such as math is pretty complicated and always using formulas.The design method that I use is the case study method, namely, learning, searching and collecting data related to the study. While the development of engineering design software application programs that will be used by the author is the method of Rapid Application Development (RAD), which consists of 4 stages: Requirements Planning Phase, User Design Phase, Construction Phase and Phase Cotuver.

With the mounting demand of web applications, a number of issues allied to its quality have came in existence. In the meadow of web applications, it is very thorny to develop high quality web applications. A design pattern is a general repeatable solution to a generally stirring problem in software design. It should be noted that design pattern is not a finished product that can be directly transformed into source code. Rather design pattern is a depiction or template that describes how to find solution of a problem that can be used in many different situations. Past research has shown that design patterns greatly improved the execution speed of a software application. Design pattern are classified as creational design patterns, structural design pattern, behavioral design pattern, etc. MVC design pattern is very productive for architecting interactive software systems and web applications. This design pattern is partition-independent, because it is expressed in terms of an interactive application running in a single address space. We will design and analyze an algorithm by using MVC approach to improve the performance of web based application. The objective of our study will be to reduce one of the major object oriented features i.e. coupling between model and view segments of web based application. The implementation for the same will be done in by using .NET framework.

Perangkat lunak komputer merupakan sebuah program komputer yang menjembatani pengguna komputer dan perangkat keras yang digunakannya. Dengan kata lain perangkat lunak merupakan penerjemah antara manusia sebagai orang yang memberi instruksi dan komputer sebagai pihak yang menerima instruksi. Perangkat lunak memang tidak tampak secara fisik dan tidak berwujud benda namun bisa untuk dioperasikan. Perangkat lunak secara garis besar software atau perangkat lunak dapat diklasifikasikan menjadi tiga bagian yaitu, perangkat lunak sistem operasi, perangkat lunak sistem aplikasi dan bahasa pemograman.Kata kunci : Perangkat Lunak KomputerAbstractComputer software is a computer program that bridges computer users and the hardware they use. In other words software is a translator between humans as the person who gives instructions and the computer as the party who receives instructions. The software does not appear physically and is not tangible but can be operated. Software outline software or software can be classified into three parts, namely, operating system software, application system software and programming languages.

Perangkat Lunak merupakan salah satu perangkat yang dibutuhkan dalam menjalankan komputer. Perangkat lunak adalah perangkat yang tidak dapat dilihat dan disentuh secara langsung, namun dapat dioperasikan oleh user atau penggunanya. Perangkat lunak komputer (software) merupakan sekumpulan data elektronik yang disimpan dan diatur oleh komputer, data elektronik yang disimpan oleh komputer itu dapat berupa program atau instruksi yang akan menjalankan suatu perintah. Perangkat lunak disebut juga sebagai penerjemah perintah-perintah yang dijalankan pengguna komputer untuk diteruskan atau diproses oleh perangkat keras. Melalui software atau perangkat lunak inilah suatu komputer dapat menjalankan suatu perintah. Secara garis besar software atau perangkat lunak dapat diklasifikasikan menjadi tiga bagian yaitu, perangkat lunak sistem operasi, perangkat lunak sistem aplikasi dan bahasa pemograman.Kata Kunci : Perangkat Lunak AbstractComputer software is one of the devices needed to run a computer. Software is a device that cannot be seen and touched directly, but can be done by the user or the user. Computer software (software) is a collection of electronic data collected and compiled by a computer, electronic data stored by a computer may consist of programs or directions that will execute an order. Software is also referred to as a translator of commands run by computer users to be forwarded or processed by the hardware. It is through this software or software that a computer can run a request. Broadly speaking, software or software can be divided into three parts, namely, operating system software, application system software and programming languages.Keywords: Computer software

Mobile software application development process must be matured enough to handle the challenges (especially market related) associated with the development of high quality mobile software development. Ever increasing number of both mobile users and mobile applications had presented software engineers with the challenge of satisfying billions of users with high quality software applications to be delivered within deadline and budgets. Always there had been a lot of pressure to develop complex software categorized by thousands of requirements, under resource constrained environment. Requirement prioritization is one of the activities undertaken by software engineer to deliver partial software product to its customers such that most important requirements are implemented in the earliest releases. During next releases some changed and pending requirements are implemented, an activity that generates ripple effects. Such ripple effects need to be tested by executing modified source code against test cases of previous releases (regression testing). Regression testing is a very effortful activity that requires a software tester to select test cases that have high fault detection capability, execute the modified code against selected test cases and performing debugging. This regression testing activity can be lowered to the maximum extend by considering dependencies between requirements during the time of requirement prioritization. Thus requirement prioritization will be carried out not only against aspects like cost, time, risks, business values etc but against dependencies also. The aim is to implement almost all dependent highest priority requirements in current release so that implementation of new requirements is unlikely to have ripple effects. Changes in requirements might not be related to variable usage and definition and might not involve a change in functionality. In such cases there is no need to select already executed test cases of previous versions. Module dependencies can lead to test case selections of previous versions if changes of requirement lead to ripple effects. This paper aims to implement highest priority requirements such that regression testing is performed to minimum thereby improving development process of mobile applications. The proposed technique had been successfully evaluated on Android based notification software application that meets the specification of Aakash tablets.

Technology is being used and improved by human beings over a long period of time now and Smartphones is one of them. Smart Phones contain touch screen, built in keyboard, high resolution camera, front side camera for video conferencing, etc. They are used for making and receiving calls, sending and receiving messages, accessing the Internet, digital media, incorporating audio/video recording etc. Different smart phones have different operating systems and mobile applications are developed for each operating system in smart phones, tablet or mobile phones, in order to serve the needs of the user. These apps are either preinstalled or downloadable from online app market that can do almost everything. Apps make a mobile be like a portable computer having multi core processors, gigabytes of memory and a real operating system. Originally mobile apps were made available for only calling, messaging and informational purposes like calendar, weather forecast, e- mail, etc. With improvement in technology and increase in user demands, developers started making apps for other purposes like games, banking, video chats etc. Some apps are also used to present data in the same format as on a computer website and also allow you to download content that you can use when there is no Internet. There are many apps available in market today for different Operating Systems in which Android is having the maximum market share these days.

The domain of the activity is technology for the society whereas the focus is practical computer science for the society. The background of our activity is based on the needs of YPK junior high school in Malang city, Indonesia. The school need to develop computer-based school report card and also daily grade card for teachers. The method for software/application development is spiral model which consist of the cycle of system identification, risk analysis, and enhancement of the prototype to be an operational prototype. Evaluation of the product was based on the Computer System Usability Questionnaire (CSUQ) from IBM. The CSUQ using 5 scale of Likert scale contains three categories: 1) system usefulness (SYSUSE), 2) information quality (INFOQUAL), and 3) interface quality (INTERQUAL). The mean rank’s result in order from the greatest to the lowest is SYSUSE, INTERQUAL, and INFOQUAL, respectively. It was reported that SYSUSE category was superior to INFOQUAL (U = 3369.5, p = 0.0005). Overall, the user satisfaction score is 78.4%, which is in the “worthy” category
