Application Development is not only limited to the business or promotional field, but it also helps to provide the necessary services to the common people across the world by creating an interaction between the companies and the customers through the website. It also creates a platform for the common people who have the ability to attract the audience using their talent. We can take the example of various blog writers, online councilors and fashion influencers who have a large audience because of their quality content and knowledge in their field. We have generally seen how the electronic companies have marked their presence on the online platform via the website which enables the users to contact the company easily. Online retail companies interact with the users via website and provide the orders at the doorsteps of the people. There are various news agencies which had created their website which keeps the users updated with the latest national and international articles. The website development has helped to create a link between the people and the companies, but behind all these facilities there is a powerful language and commands that holds these computational activities and data transfers which helps to create a good interaction between the users and the website owners. Web developers are classified into Front-end and Back-end web developers, Front-end developers help to create an interactive interface that can be easily accessed by the users, whereas Back-end development deals with the main work that is done behind the screens. We can say that it helps to power the website by managing data transfer and other computational activities. In this project, the importance of Django and back-end web development is explained. Using the tools and commands of these languages we can make an interactive and user-friendly interface that can be easily accessed by people. Back-end was earlier known for limited purposes but now when it is explored thoroughly proved to be one of the best languages for website development, gaming, Artificial Intelligence, and highly advanced mobile applications.

In today's era of globalization, websites are very familiar, where many people easily use the web or website. Some can make their own and some ask for it to be made or rather buy. Just use it and then we just need to use it. Our partners are neighborhood associations 05 and 06 which are located in Perumnas Depok Timur, which have young women and men who are curious about website development, and some young women and men want to continue their studies at a higher level by majoring in information and communication. In making a website, they need several stages that they have to apply because our partners are teenagers who are unfamiliar with website creation, for that we here want to make a basic training in website creation which will later be useful for them in terms of application in their environment and society. Where in this training introduced HTML (hypertext markup language). It is hoped that by studying HTML, teenagers can understand how to create a website with HTML.

There are a growing number of jobs related to web development, yet there is little formal literature about the accessibility of web development with a screen reader. This article describes research to explore (1) web development accessibility issues and their impact on blind learners and programmers; (2) tools and strategies used to address issues; and (3) opportunities for creating inclusive web development curriculum and supportive tools. We conducted a Comprehensive Literature Review (CLR) to formulate accessibility issue categories, then interviewed 12 blind programmers to validate and expand on both issues in education and practice. The CLR yielded five issue categories: (1) visual information without an accessible equivalent, (2) orienting, (3) navigating, (4) lack of support, and (5) knowledge and use of supportive technologies. Our interview findings validated the use of CLR-derived categories and revealed nuances specific to learning and practicing web development. Blind web developers grapple with the inaccessibility of demonstrations and explanations of web design concepts, wireframing software, independent verification of computed Cascading Style Sheets (CSS), and navigating browser-based developer tool interfaces. Tools and strategies include seeking out alternative education materials to learn independently, use of CSS frameworks, collaboration with sighted colleagues, and avoidance of design and front-end development. This work contributes to our understanding of accessibility issues specific to web development and the strategies that blind web developers employ in both educational and applied contexts. We identify areas in which greater awareness and application of accessibility best practices are required in Web education, a need to disseminate existing screen reader strategies and accessible tools, and to develop new tools that support Web design and validation of CSS. Finally, this research signals future directions for the development of accessible web curriculum and supportive tools, including solutions that leverage artificial intelligence, tactile graphics, and supportive-online communities of practice.

The research is discussing the relevance of web technology based on its history, current development, future working process, threats, or attacks that are common in web technology, and its solutions to encounter the threats. Nowadays, web services have become one of the most vital components in peoples' daily lifestyle. People are talking how the advancement in the technology leads the world now. The evolution of network has triggered the demands especially in internet connection as everyone around the world are depending on the connection to do their activities especially for communication. It is required to have high speed internet and bandwidth to prevent poor connection. Besides that, due to advance development in computing products and network, people enables to catch up with the current trends which spark the existence of web development that are used to gather information.

Dashboard are relied upon to improve dynamic by enhancing cognizance and gaining by human perceptual capacities. Subsequently, premium in dashboards has expanded as of late, which is additionally obvious from the expansion of dashboard arrangement suppliers on the lookout. Regardless of dashboards' fame, little is thought about the degree of their viability, for example what sorts of dashboards turn out best for various clients or undertakings. In this paper, we direct a complete multidisciplinary writing survey with a plan to recognize the basic issues associations may have to consider while actualizing dashboards. Dashboards are probably going to succeed and take care of the issues of introduction organization and data load when certain perception standards and highlights are available (for example high information ink proportion and drill down highlights). We suggest that dashboards accompany some degree of adaptability, for example permitting clients to switch between elective introduction designs. Additionally, some hypothesis driven direction through pop-ups and alerts can assist clients with choosing a fitting introduction design.In this dashboard user can get notes of all subjects as well as all the stuff which help him grabbing a good job and also provide internships notification to users.The machine learning helps them what they require and the best result will come for them to support them.This also give the option of chatting so they can chat among the other users for any help.This also use cloud for saving their data and for faster access.So, this dashboard use web development, cloud and machine-learning and the languages for this are mainly Html,css,Bootstrap,Javascript and Php and some sqlUsers will provide the notification of many events like exam and hackathon through this dashboard.

The range of applications of artificial intelligence (AI) that is based on nature-inspired metaheuristics is rapidly increasing across various scientific fields as it is used to solve complex engineering problems. This work develops a cloud evolutionary machine learning system, called the nature-inspired metaheuristic optimization and prediction system (NiMOPS) that is composed of metaheuristic AI and web modules. The objective of the proposed system is to provide a user-friendly web analytics for making efficient, effective, and accurate predictions as solutions to engineering problems. For the purposes of web development, this work connects two programming languages, which are MATLAB and Java. A MATLAB Compiler is used to package the system into Java Archive (JAR) files, which provide the core modules for the development of the NiMOPS website using an integrated development environment (IDE). IDE compiles the JAR files, and web utilities (JavaScript, CSS, Servlet, and other utility files) to form the response-request connection between the user and the server. Therefore, the web-based system does not require the installation of an application by the users because they can access the cloud computing system ubiquitously with a browser or mobile device. Furthermore, it has many functions, including export—import file, train model, optimize prediction, save model and visualize results. Several case studies of this system, involving classification and regression problems, were examined. The analytic results of using the system to solve classification problems revealed that the system had a fault diagnosis accuracy of 96.5% and an accidental small fire accuracy of 52.4%. In solving regression problems, the root mean square errors were 28.58–68.82% better than those of previous methods. In particular, the proposed system performed multiple performance measures that were utilized in a regression analysis and were found to be more reliable evaluation metrics than used in elsewhere. The numerical experiments verified that cloud computing provides an innovative way to enable decision-makers to solve engineering problems.

The clinic as one of the public service agencies requires the awareness of an accurate and reliable information system, and is adequate to improve its services to patients and other related environments. With such a wide scope of service, of course there are many complex problems that occur in the service process in the clinic. The number of variables in the clinic also determines the speed of information flow required by users and the PHP clinic environment can also be integrated with HTML, JavaScript, Jquery, and Ajax. However, in general PHP is more widely used in conjunction with HTML-type files. By using PHP we can create a dynamic powerful website with the accompanied database management. In addition, the use of PHP, which can mostly be used on many platforms, is one of the reasons why you have to master PHP to become a reliable web development.

Many industries produce waste that cannot be reused, especially in the process of cutting raw materials. The use of raw materials that are not optimal indicates that the pattern of item placement on raw materials produces waste which cannot be used for other needs. This problem is known as cutting stock problem. This study aims to reduce the waste that arises when cutting raw material sheets into small pieces needed in the industry by developing a website as a tool in completing the placement of cutting patterns on raw materials. The developed website describes the results of optimal placement patterns in the form of images for 1 and 2 dimensions with the genetic algorithm method as an optimization algorithm using rectangle packing sequence in codification, cornerset modification algorithm on decoding, parameterized uniform crossover on crossover, roulette wheel on selection, and random generated mutations. Website development is made with hypertext markup language to display various information needed, cascading style sheets to arrange components in structured and uniform websites, and javascript to create genetic algorithm logic. This research resulted in the placement of cutting patterns on sheets of raw material on the canvas by labeling the names of each item.

Nowadays, operation management performed by electronic systems in different life sectors is distributed and expanded swiftly due to several advantages that can be achieved, such as time reduction process, simplicity, and high accuracy of running operations. In the educational sector, performing student feedback electrolytically (using PC, Tablet, or Mobile) rather than the ordinary paper-based methods saves staff and students' time and makes managing the data easier. This paper proposes a new approach for the Electronic Student Feedback Management System based on web programming, which consists of input, process, store, and retrieves information using a database. The system is based on the Accreditation Board for Engineering and Technology (ABET) questionnaire model, which is implemented using web development tools (HTML, CSS, Javascript, MySQL, and PHP with Apache web-server). As a result, the proposed system was implemented successfully. The Electronic Engineering College officially adopted it at Ninevah University to perform the student feedback for the academic year 2018-2019, in which 4,282 student feedback applications (SFA) have been recorded. After that, statistical operations were done for extracting useful information effortlessly and accurately. As a result, more than 800 students made 4282 records have participated in the proposed system. This information can be quickly recorded and utilized to identify the weaknesses to address them in the next academic year.

Movement data exploration presents a significant challenge due to the heterogeneity of movement datasets and analysis tasks. Furthermore, there is a lack of established tools for the exploratory analysis of movement data, as well as a lack of literature on best practices for applying corresponding concepts using commonly available data analysis tools. To address this gap, we present three open-source technology stacks for the exploratory analysis of movement data and discuss their capabilities and limitations.

The rapid growth in the number and diversity of Web APIs, coupled with the myriad of functionally similar Web APIs, makes it difficult to find most suitable Web APIs for users to accelerate and accomplish Mashup development. Even if the existing methods show improvements in Web APIs recommendation, it is still challenging to recommend Web APIs with high accuracy and good diversity. In this paper, we propose an integrated content and network-based service clustering and Web APIs recommendation method for Mashup development. This method, first develop a two-level topic model by using the relationship among Mashup services to mine the latent useful and novel topics for better service clustering accuracy. Moreover, based on the clustering results of Mashups, it designs a collaborative filtering (CF) based Web APIs recommendation algorithm. This algorithm, exploits the implicit co-invocation relationship between Web APIs inferred from the historical invocation history between Mashups clusters and the corresponding Web APIs, to recommend diverse Web APIs for each Mashups clusters. The method is expected to not only find much better matched Mashups with high accuracy, but also diversify the recommendation result of Web APIs with full coverage. Finally, based on a real-world dataset from ProgrammableWeb, we conduct a comprehensive evaluation to measure the performance of our method. Compared with existing methods, experimental results show that our method significantly improves the accuracy and diversity of recommendation results in terms of precision, recall, purity, entropy, DCG and HMD.

Multimedia based virtual learning system (MMVLS) is a web-based platform for teaching and learning with a virtual teacher within a virtual classroom. This research was motivated by the problems confronting the traditional institutions of higher learning in Nigeria which include inadequate funding, lack of infrastructures, inadequate teaching and learning facilities, limited slots for admission known as carrying capacity, a limited number of lecturers/instructors in the tertiary institutions in Nigeria. The objective of this research is to develop a multimedia based virtual learning system for Nigerian tertiary institutions to be used in academic processes for teaching and learning. The methodology used is Object Oriented Design Methodology (OODM) with the following web development tools PHP, JavaScript, Bootstrap 3, HTML5, CSS4, Apache, and MYSQL as database. The expected result is a multimedia based virtual learning system for tertiary institutions in Nigeria which is cost effective, innovative, vibrant, individualized, learner-centric, available anytime, any place even with mobile devices. It was concluded that multimedia based virtual learning system is a veritable tool for Nigerian tertiary institutions, which when fully implemented by Nigerian tertiary institutions would help to increase the number of candidates that are given admission into our tertiary institutions and drastically reduce school dropouts as a result of candidates not gaining admission due to insufficient tertiary institutions/carrying capacity.

In the good old days of web development, things were simple. You created a directory, maybe some subdirectories, if you were a bit more organized, and into it, you poured all your resources: a stylesheet or two here, a sprinkling of images, some HTML files, and a heaping helping of JavaScript files. Then, a single HTML file served as your entry point, and it would go out and load, by way of script tag references, to load all your JavaScript files, as well as your CSS files and images.

The correct creation of the site is responsible for the correct display of the content. The developer must create web-page, that will be displayed correctly in the browser, which will be the closest to the previously created layout design site, pre-designed in the graphic editors. There are many tools for creation websites, for example html, css, and different types of frameworks. There are «hard» (fixed) and «rubber» (adaptive) layout of the site. «Hard» layout makes all elements of the web page of fixed sizes, regardless of the size of the user’s monitor and the screen resolution set. Adaptive layout of the site allows you to resize page elements by adjusting to different sizes and permissions of monitors. The most significant and actively explored area of web development is adaptive layout. Due to the large variety of technologies that allow us to solve a number of problems facing the developer when designing adaptive websites, it’s worth researching the most effective ones. The article explores flexbox technology for adaptive web page development. The main features of the flexbox application are highlighted for solving basic tasks such as moving the blocks accordingly to the width of the screen, automatically determining the center for precise alignment of the containers on the page. The main features of the flexbox are for seeing the main headlines, such as the one for the graphic content of the screen width, which is automatically assigned to the center for the exact virtual container on the web-page. We explored the main advantages and perspectives of using flexbox technology in adaptive web page designing that contain dynamic content, which gives a clear idea of the further introduction of this technology into the web development process. Adaptive layout is used for correct display. To implement the adaptability of the site, additional styles are prescribed, which, in addition to the greater amount of work, entail thinking of the behavior of each element.

In recent time, the evolution of web applications have gained importance over the web development process and the factor of web evolution cannot be ignored by web developers. Web development has become complex and challengeable for web developers. The process of software evolution played an important role during the development of the software. Millions of web application have been developed every year around the world It has included various approaches, tools, and frameworks to reorganize the web applications with an improved version. Research has been shown that there are no proper and systematic techniques is available for evolving web applications. This special article has been written to make a comparative analysis of WordPress and Django web framework using Lehman’s laws of software evolution. It has been found that the six out of eight Lehman’s laws found valid during the evolution process for web frameworks.

Weaver discusses the Where to Publish, a website that takes a user's keyword search and returns data to address several concerns. WTForms, a Python module for generating and validating form input in web platforms, receives the user's search terms. The site's core script uses the Biopython module, which includes the National Library of Medicine's Entrez application programming interface, to return journals ranked by the number of times the journal has published papers that fit the search criteria. Where to Publish uses Clarivate Analytics' journal impact factor (JIF) as an indicator of journal quality in two respects. First, JIF is used by Cleveland Clinic in physicians' annual performance reviews. Second, by providing a list of journals with JIFs, Where to Publish ensures that authors will avoid low-quality journals due to Clarivate's rigorous journal selection criteria, especially as predatory journals have been getting their papers into PubMed via PubMed Central.

In this paper, a social media platform like LinkedIn and Facebook is made using MongoDB as a database. This paper aims to touch all the modern tools required to make an efficient web app, keeping in mind both the customer satisfaction and the ease for the developers to make their web designs, front-end and back-end. In this application, a user could make an account, add or delete details of their profile, education, and experience fields. The users could post, also comment and even like a post of other users. A monolithic architectural approach is used for simplicity in maintaining the database. Postman application programming interface (API) was used to check the working of the back-end. Git, Github, and Heroku were used to deploy the website. Node package manager (NPM) packages like bcrypt and validator are used to encrypt passwords and to validate a user during login. Media queries are used in cascading style sheets (CSS) to achieve a responsive design. Therefore, the users could view the website through a mobile phone, i-pad and also a personal computer (PC), maintaining the readability and design across all these devices.

The learning process in the STKIP PGRI West Sumatra Informatics Education Study Program still uses conventional learning methods, namely through face-to-face contact between lecturers and students in the class. The traditional learning method currently taking place has limitations that can hinder the learning process, such as limited time and space to interact with each other, especially during the Covid-19 pandemic. With these conditions, the online learning process is an alternative to support learning in its current state, with technological developments that can simplify the learning process and make the time more flexible and support the learning process anywhere, anytime, and anyone. An electronic learning system (E-Learning) was created from these conditions, which is expected to be an alternative solution for online learning to overcome the STKIP PGRI West Sumatra Informatics Education Study Program's limitations, especially in introductory web programming courses. E-learning is designed using the System Development Life Cycle (SDLC) method supported by the PHP programming language and implementing the Laravel Framework. The learning process using E-learning is designed using localhost as the central server. This study's results resulted in an E-learning application built based on the analysis and design recommended by the STKIP PGRI West Sumatra informatics education study program. With this application, it is hoped that it can simplify the online learning process, especially in existing introductory web programming courses.

It selects dynamic configurable data based on time objective function and comprehensive objective function, and designs a configurable data collection system. The simulation experiment results show that the data collection precision of this system is higher, more accurate and more feasible.

JavaScript has become one of the most widely used programming languages for web development, server-side programming, and even micro-controllers for IoT. However, its extremely functional and dynamic features degrade the performance and precision of static analysis. Moreover, the variety of built-in functions and host environments requires excessive manual modeling of their behaviors. To alleviate these problems, researchers have proposed various ways to leverage dynamic analysis during JavaScript static analysis. However, they do not fully utilize the high performance of dynamic analysis and often sacrifice the soundness of static analysis. In this paper, we present dynamic shortcuts, a new technique to flexibly switch between abstract and concrete execution during JavaScript static analysis in a sound way. It can significantly improve the analysis performance and precision by using highly-optimized commercial JavaScript engines and lessen the modeling efforts for opaque code. We actualize the technique via SAFEDS, an extended combination of SAFE and Jalangi, a static analyzer and a dynamic analyzer, respectively. We evaluated SAFEDS using 269 official tests of Lodash 4 library. Our experiment shows that SAFEDS is 7.81x faster than the baseline static analyzer, and it improves the precision to reduce failed assertions by 12.31% on average for 22 opaque functions.

Mind Frame is a web-application designed in proposed work that gives recommendations of music and movies to users based on their current mood. The proposed system identifies moods of the user such as happy, sad, peaceful and gives music and movie recommendations to the user based on mood identified. The OpenCV library of Python is used to extract the features from the facial expressions. Neural network is trained with labelled images of different emotional moods of the user, this trained model is then used to predict the mood of the user. Finally, the user is recommended the playlists of music or movies from the library created containing over hundred thousand music and movies. For storing and viewing the data and user details and also for processing requests from each user, Django is used as the web framework along with Python for front end and back-end.

Introduction. The article presents the results of the investigation of the impact of new information and communication technologies, namely Internet technologies of the social web, on the linguistic consciousness in the learning environment. The term covers a certain concept of the Global Web development, when the main functional task of a web service is aimed at maintaining interaction between network users. The method of a free and directional associative experiment was chosen as main research technique. It allows most accurately identifying the meaning of the word, seeing what is behind this word in the linguistic consciousness of a person. Associative series were identified for a number of concepts – the most popular social web services and Internet technologies (Internet, Instagram, social media, communication, Twitter, Telegram, WhatsApp, Youtube, Pinterest, Google, selfie). Results. The associative experiment showed that information, communicative and functional components of the Global net are actualized in the linguistic consciousness of the participants of the educational process most of all. Almost all social media services have both positive and negative connotations. The educational component of social media has been marked little, if at all, in the linguistic consciousness of the recipients which indirectly indicates that their use in the educational process has not become an institutional practice yet. Conclusions. The results of the research will contribute to the development of a new direction in modern linguistics – psycholinguistics 2.0 which studies psychological and linguistic aspects of human speech in social media, social and psychological aspects of using language in speech communication using web 2.0 platforms and services, and in individual verbal and thinking activity. The study is characterized by an interdisciplinary nature, being at the interface of psycholinguistics 2.0 and education 2.0, which contributes to a better understanding of the polyparadigmatic way of the development of humanitarian knowledge under the influence of technologies in general.

LKSA prasejahtera is a group of mothers who have todlers with poor phisically growth due to their poor daily nutrition. Those children’s problems because of their parents have low income and cannot suport their family. Therefore, the purpose of our program is to help them build an UKM online in order to help them increase their income. This UKM-online is very suitable for their business because of affordable for them compare with the conventional business. These people in the LKSA group do not need rent a place to run their business anymore so they can save more money as we know that the price to rent a strategic place is very high. Howevert, they still can able to run their business and reach more people even they do not have a strategic place. So the website able to help any kind of business because of it provide more detail about their product to many people in unlimeted range. However, this method still needs an expertice in website development in order to build an UKM websites.There are, three type of web developer which are front-end developer, back-end developer,and full-stack developer. Each of web developer has a different function and duty. While, programming language that usually is used in website programming which are, HTML,CSS, Javascript, PHP,and Java. Therefore, the output of this program is expected to be the progress of the business by utilysing an ukm-website. So the underpriviliged people are extpected able to increse their income as well as able to run their business eficient and easy.While, people outside of the LKSA also can take benefit from this ukm-online, because their eficiency of time, place,and budget is also increase and that will make their life more easy and less stress.

Uniform Resource Locators reveal a significant amount of metadata about user actions, in ways that inherently violate our natural expectations of privacy. Adequately protecting this information is an important issue tackled (sometimes partially) in areas such as secure transport protocols, terminal encryption and caching strategies. A different (and complementary) approach would be to design the application namespace to minimise privacy leakage. Our goal is to develop a different practical concept of this approach, where service providers enforce fully transient URL namespaces that intentionally conceal data through encryption. We aim to determine what would be the design challenges and required compromises to make this a feasible technique to protect data privacy. For starters, we gather requirements from the constraints of URLs in general and compatibility issues seen in web applications, and propose a mapping process for a namespace of encrypted URLs. We implement this approach over an existing web development framework, and analyse the outcome workload from different popular websites to measure its impact in various conditions. Based on our results, we discuss critical design and implementation choices, consider deployment issues that were encountered, and what compromises can be made to address them, if the web service providers want to embed user privacy in their services. Based on this analysis it can be concluded that this type of privacy approach is expensive, with a significant impact in performance and deployment costs that increases with the expected degree of privacy, but there is also room for improvement in various areas. Furthermore, privacy implemented in this way is not a replacement for other types of privacy solutions, but rather a complementary or even conflicting approach, driven by entirely different motives.

Online resources can help novice developers learn basic programming skills, but few resources support progressing from writing working code to learning professional web development practices. We address this gap by advancing Readily Available Learning Experiences, a conceptual approach for transforming all professional web applications into opportunities for authentic learning. This article presents Isopleth, a web-based platform that helps learners make sense of complex code constructs and hidden asynchronous relationships in professional web code. Isopleth embeds sensemaking scaffolds informed by the learning sciences to (1) expose hidden functional and event-driven relationships, (2) surface functionally related slices of code, and (3) support learners manipulating the provided code representations. To expose event-driven relationships, Isopleth implements a novel technique called Serialized Deanonymization to determine and visualize asynchronous functional relationships. To evaluate Isopleth, we conducted a case study across 12 professional websites and a user study with 14 junior and senior developers. Results show that Isopleth’s sensemaking scaffolds helped to surface implementation approaches in event binding, web application design, and complex interactive features across a range of complex professional web applications. Moreover, Isopleth helped junior developers improve the accuracy of their conceptual models of how features are implemented by 31% on average.

JavaScript is a powerful scripting programming language that has gained a lot of attention this past decade. Initially used exclusively for client-side web development, it has evolved to become one of the most popular programming languages, with developers now using it for both client-side and server-side application development. Similar to applications written in other programming languages, JavaScript applications contain code smells, which are poor design choices that can negatively impact the quality of an application. In this paper, we perform a large-scale study of JavaScript code smells in server-side and client-side applications, with the aim to understand how they impact the fault-proneness of applications, and how they are evolved by the developers of the applications. We detect 12 types of code smells in 1807 releases of 15 popular JavaScript applications (i.e., express, grunt, bower, less.js, request, jquery, vue, ramda, leaflet, hexo, chart, webpack, webtorrent, moment, and riot) and perform survival analysis, comparing the time until a fault occurrence, in files containing code smells and files without code smells. We also examine the introduction and removal of the code smells in the applications using survival models. All our analysis are conducted at the granularity of the line of code. Results show that (1) on average, files without code smells have hazard rates at least 33% lower than files with code smells. (2) Among the studied smells, “Variable Re-assign,” “Assignment In Conditional statements,” and “Complex Code” smells have the highest fault hazard rates. (3) Code smells, and particularly “Variable Re-assign,” are often introduced in the application when the files containing them are created. Moreover, they tend to remain in the applications for a long period of time; “Variable Re-assign” is also the most prevalent code smell. Overall, code smells affect negatively the quality of JavaScript applications and developers should consider tracking and removing them early on before the release of applications to the public.

Learning abilities vary among individuals, yet schools teach them in one classroom. Managing learning abilities could be difficult. This Online Course Management System integrates learning techniques which addresses this problem. The aim of this work therefore is to develop an adaptative e-Learning Software to enable the learner answer questions or solve problems based on his/her ability. This work is motivated by the need to address deep concern and awareness toward how learners learn best. This study develops an adaptive e-learning platform where the learner is allowed to answer questions or solve problems based on his/her ability or pace. It also provides an online classroom which will run alongside the traditional classroom. The software will adopt the waterfall model. VB.NET, an Object Oriented Programming Language will be used with AJAX and JAVASCRIPT web development tools. Furthermore, this study recommends new strategies & technologies to improve safety, quality, and overall standard of learning amongst learners in educational institutions.

Most websites use interactive online forms as the main contact point between users and website owners (e.g. companies, governmental institutions, ect.). Therefore, a proper design of such forms is crucial to allow smooth information exchange. It can be decisive on the success or failure of an online transaction. Users mostly visit a website with an intention that is related to the content of that site (e.g. purchasing an article, gathering information). Hence, they do not visit a website with the intention or goal of filling in a web form. Let us illustrate this with an online shopping example: Once users have chosen the items that they wish to buy, they want to finish their shopping as quickly, easily and safely as possible. But to successfully complete the shopping process users have to provide some personal data such as shipping address or credit card information. In the users perception, an online form may be perceived as a hurdle. There is evidence that unusable web forms lead to customers aborting the transaction prematurely, resulting in loss of profit (Wroblewski, 2008). To prevent such dropouts from the buying process, a revision of the form is necessary. A successful redesign of a suboptimal online form may result in an increased completion rate in the range of 10%-40% (Wroblewski, 2008). For instance, the eBay User Experience and Design Group reported that a redesign of the eBay registration form made a significant contribution to eBay’s business and user success (Herman, 2004). The World Wide Web contains a wide range of different web form design solutions for similar interface aspects and problems. Exemplarily, Figure 1 shows four different ways of implementing and communicating format restrictions to users. It can be seen, that even website developers of major companies choose very different ways to solve the same problems. This raises several important questions: Are these solutions equivalent or are there ways that lead to superior web forms in terms of an enhanced usability? Would it not be advantageous to use similar solutions for similar problems, so that predictability for users can be increased? Are there different solutions that may be used depending on the developer’s intentions? In the last years a growing body of research and guidelines have been published on how to make online forms more usable. They answer to a certain extent the questions mentioned

The paper presents an approach to developing new educational programs for information technologies (IT) specialists using job market analysis. We developed a set of innovative software tools for collecting data from job sites and analyzing the data using machine learning algorithms. The tools were used to create a dataset of job advertisements from popular Russian job site HeadHunter for a period from 2006 until 2020. Both tools and dataset are freely available on the Internet. In order to develop the educational programs, we analyzed the demand for IT professions and programming languages, as well as joint occurrence of skills in job descriptions. To demonstrate the possibilities of our approach, two educational programs were created: a JavaScript-based program for Web Development and a Python-based program for Data Science. Developing the educational programs based on the requirements of the job market allows graduates to increase their employability. During the programs, students not only study the foundation of the profession such as programming languages, but also acquire a complete set of skills required to work in demanded positions.

Website security is a major concern for large organizations as well as individual developers, the rarer the technology used the harder it becomes to come up with secure practices for developing a website. Vulnerabilities that are not fixed during development, and are deployed as such become easy targets for hackers. This could cause the company or the individual to lose a lot of money. It is not just the developers who are affected, end users who end up on vulnerable websites may get exposed to XSS attack which could compromise their system or an unsecured configuration of database system could lead to a potential data leak and hence the password of every registered user on the website is compromised, users who use the same password on multiple websites are affected the most The motivation for this paper comes from the fact that there is an overwhelming number of vulnerabilities in any application under development and every developer, experienced or not needs a starting point to patch these vulnerabilities that might have occurred in their application, this research provides the most common vulnerabilities which should be taken care of in any application and thus provide the much-needed starting point for developers. The objective of this paper is to design and develop a secure web application according to Open Web Application Security Project (OWASP) guidelines. This paper highlights the mitigation of vulnerabilities in the web application using configuration changes, coding and applying patches. The vulnerabilities SQL injection, Broken authentication, Sensitive data exposure, Broken Access Control, and XML external entities discussed in this paper are listed under the OWASP top 10 vulnerabilities. The security of the web application is tested and proved to have defense mechanism implemented for the mentioned vulnerabilities.

To meet the functional requirements of college students' network ideological and political education informatization, this paper puts forward the overall model of mobile innovation platform of Ideological and political education based on the mobile client of E-class, and Android environment. According to the requirement analysis of the system, we provide the overall design and architecture of the platform. Then, with web development and mobile communication technology as the core, the detailed design and implementation of each functional module are described combined with the user authentication data interface provided by E-class open platform. Finally, JSP script is used to complete the development of app, and the test and analysis are performed in the actual work. The results show that the system runs stably and performs well. It not only opens up the interface between E-class users and ideological and political education teaching, but also provides friendly experience for students.

With tons of efforts spent on its mitigation, Cross-site scripting (XSS) remains one of the most prevalent security threats on the internet. Decades of exploitation and remediation demonstrated that code inspection and testing alone does not eliminate XSS vulnerabilities in complex web applications with a high degree of confidence. This paper introduces Google's secure-by-design engineering paradigm that effectively prevents DOM-based XSS vulnerabilities in large-scale web development. Our approach, named API hardening, enforces a series of company-wide secure coding practices. We provide a set of secure APIs to replace native DOM APIs that are prone to XSS vulnerabilities. Through a combination of type contracts and appropriate validation and escaping, the secure APIs ensure that applications based thereon are free of XSS vulnerabilities. We deploy a simple yet capable compile-time checker to guarantee that developers exclusively use our hardened APIs to interact with the DOM. We make various of efforts to scale this approach to tens of thousands of engineers without significant productivity impact. By offering rigorous tooling and consultant support, we help developers adopt the secure coding practices as seamlessly as possible. We present empirical results showing how API hardening has helped reduce the occurrences of XSS vulnerabilities in Google's enormous code base over the course of two-year deployment.

To accurately grasp the characteristics and needs of the object, and enhance the pertinence and effectiveness of evening teaching of Ideological and political theory course, this paper designs an online teaching platform assisted by big data technology. According to the actual needs of the network teaching model, we make the overall planning and design of the functional modules of the platform. Then, in the key module of user classification and location, feature sets related to learning behavior are extracted from learners' behavior data, and a personalized model of user portrait based on improved K-means algorithm is constructed. Through the big data platform based on Hadoop distributed cluster, combined with data analysis algorithm, the data set is cleaned, standardized, analyzed and processed, and the user interests and preferences are analyzed. Finally, the function of the system is tested through web development, and the results show that our scheme can depict the different characteristics of learners, which provides a scientific basis for personalized recommendation and auxiliary learning of Ideological and political education.

The COVID-19 pandemic exacerbated the lack of accessible tech skills training for screen reader users. To address this gap, we developed remote tools and techniques to support screen reader users in learning web development. In this paper, we describe our design and implementation of a free, remote web development workshop, designed to introduce 12 screen reader users to HTML, CSS, and JavaScript. We taught the workshop remotely using synchronous lectures followed by 1-on-1 time with teaching assistants (TAs), and included a resource-rich website, tactile diagrams, and discussion forum. We evaluated the impact of the workshop, as well as techniques and tools using pre- and post-workshop surveys, observational field notes, exit interviews, and unit quizzes. At the end of the workshop, all students demonstrated their knowledge of web development basics by creating and publishing their own websites; showed an increase in self-efficacy; and maintained a high level of interest in the subject. Participating in this workshop benefited our TAs who reported increased confidence in understanding accessibility concepts, increased interest in pursuing work related to accessibility, and plans to apply what they learned. Based on these findings, we recommend techniques and tools to support remote screen reader users learning web development; and suggestions for engaging with post-secondary institutions to pair service learning with tech skills training. We close with recommendations for implementing and adapting the workshop using our open-educational materials.

Modern game engines like Unity allow users to create realistic 3D environments containing terrains as well as natural and artificial objects easily and swiftly. In addition, recent advances of game engine capabilities enable effortless implementation of virtual reality (VR) compatibility. 3D environments created with VR compatibility can be experienced from an egocentric and stereoscopic perspective that surpasses the immersion of the "classical" screen-based perception of 3D environments. Not only game developers benefit from the possibilities provided by game engines. The ability to use geospatial data to shape virtual 3D environments opens a multitude of possibilities for geographic applications, such as construction planning, spatial hazard simulations or representation of historical places. The multi-perspective, multimodal reconstruction of three-dimensional space based on game engine technology today supports the possibility of linking different approaches of geographic work more closely. Free geospatial data that can be used for spatial reconstructions is provided by numerous national and regional official institutions. However, the file format of these data sources is not standardized and game engines only support a limited number of file formats. Therefore, format transformation is usually required to apply geospatial data to virtual 3D environments. This paper presents several workflows to apply digital elevation data and 3D city model data from OpenStreetMap and the Open.NRW initiative to Unity-based 3D environments. Advantages and disadvantages of different sources of geospatial data are discussed. In addition, implementation of VR compatibility is described. Finally, benefits of immersive VR implementation and characteristics of current VR hardware are discussed in the context of specific geographic application scenarios. Moderne Spiel-Engines, wie zum Beispiel Unity, ermöglichen es Nutzern realistische 3D-Umgebungen, die sowohl Terrains, als auch natürliche und künstliche Objekte enthalten, einfach und schnell zu erstellen. Zusätzlich ermöglichen die jüngsten Fortschritte von Game-Engine-Funktionen die mühelose Implementierung von Virtual Reality (VR)-Kompatibilität. VR-kompatible 3D-Umgebungen können aus einer egozentrischen und stereoskopischen Perspektive erlebt werden, die die Immersion der „klassischen“ bildschirmbasierten Wahrnehmung von 3D-Umgebungen übertrifft. Nicht nur Spieleentwickler profitieren von den Möglichkeiten der Spiel-Engines. Die Möglichkeit, Geodaten zur Gestaltung virtueller 3D-Umgebungen zu verwenden, eröffnet eine Vielzahl von Möglichkeiten für geografische Anwendungen wie Bauplanung, räumliche Gefahrensimulationen oder die Darstellung historischer Orte. Die multiperspektivische, multimodale Rekonstruktion des dreidimensionalen Raums auf der Grundlage der Game-Engine-Technologie ermöglicht es heute verschiedene Ansätze der geografischen Arbeit enger miteinander zu verknüpfen. Kostenlose Geodaten, die für räumliche Rekonstruktionen verwendet werden können, werden von zahlreichen nationalen und regionalen öffentlichen Institutionen bereitgestellt. Die Dateiformate dieser Datenquellen sind jedoch nicht standardisiert und Spiel-Engines unterstützen nur eine begrenzte Anzahl von Dateiformaten. Daher ist normalerweise eine Transformation der Dateiformate erforderlich, um Geodaten in virtuelle 3D-Umgebungen zu übertragen. In diesem Artikel werden verschiedene Workflows zum Anwenden digitaler Höhenmodelldaten und 3D-Gebäudemodelldaten von OpenStreetMap (OSM) und der Open.NRW-Initiative auf Unity-basierte 3D-Umgebungen vorgestellt und die Vor- und Nachteile verschiedener Geodatenquellen erörtert. Zusätzlich wird die Implementierung der VR-Kompatibilität beschrieben. Zum Abschluss werden die Vorteile einer immersiven VR-Implementierung und die Eigenschaften aktueller VR-Hardware im Kontext spezifischer geografischer Anwendungsszenarien erörtert.

The World Wide Web (the Web) is rapidly transforming many business practices. The purpose of this chapter is to show readers how facility management tools provided by application service providers (ASPs) via the Web may represent a simple, cost-effective solution to their facility and energy management problems. All participants in the management of a facility, from building operations staff to tenants, can get convenient access to information and tools to meet their needs more effectively by simply using a web browser and an Internet connection. Further, energy tools that are integrated into these facility management software environments become readily accessible and can be linked to other tools for managing work orders for getting energy-wasting problems fixed. The chapter also describes how the Federal Energy Management Program (FEMP) is working to make such energy tools readily available.

Due to the unclear entity relationship logic of the traditional online teaching platform, the security of the platform is insufficient in practical application. Therefore, the design of online teaching platform for printing color course based on visualization technology is proposed. The platform architecture is designed based on B/S mode and PHP web development framework. With the support of the architecture, the database is designed to provide data support for the retrieval function of the design, meet the operation needs of users for teaching resources, and intuitively display the required teaching information to users through the designed visual page or interactive device. So far, the design of online teaching platform is completed. The experimental results show that: the designed online teaching platform of printing color course based on visualization technology has low memory leakage probability, fast response time and high fault tolerance rate, and its overall security performance is better than the traditional online teaching platform.

Users of the services can interact with the application using a browser or using mobile devices. The most popular mobile platforms today are iOS and Android. Development of any service includes backend (application logic, database) and frontend (interface) part. Development of frontend part for web, iOS and Android parts is carried out separately, but you can use a single API, which is implemented in the backend part, instead of implementing different backend parts for each platform. In this article, we will consider the architecture of a single API and describe the methodology of its development, which allows you to save resources when creating a service.

In the previous chapter, we learned how to create a space shooter with Pygame. We learned all about shooting at characters, collision detection, rendering text on a Pygame screen, and so much more.

In the previous chapter, we learned about web development with Python. We took a brief look into HTML, CSS, and JavaScript, and we created your first program with Flask. In this chapter, let’s create some more mini projects with the Python concepts you’ve learned in this book.

As the SQL injection attack is still at the top of the list at Open Web Application Security Project (OWASP) for more than one decade, this type of attack created too many types of issues for a web application, sensors, or any similar type of applications, such as leakage of user private data and organization intellectual property, or may cause Distributed Denial of Service (DDoS) attacks. This paper focused on the poor coding or invalidated input field which is a big cause of services unavailability for web applications. Secondly, it focused on the selection of program created issues for the WebSocket connections between sensors and the webserver. The number of users is growing to use web applications and mobile apps. These web applications or mobile apps are used for different purposes such as tracking vehicles, banking services, online stores for shopping, taxi booking, logistics, education, monitoring user activities, collecting data, or sending any instructions to sensors, and social websites. Web applications are easy to develop with less time and at a low cost. Due to that, business community or individual service provider’s first choice is to have a website and mobile app. So everyone is trying to provide 24/7 services to its users without any downtime. But there are some critical issues of web application design and development. These problems are leading to too many security loopholes for web servers, web applications, and its user’s privacy. Because of poor coding and validation of input fields, these web applications are vulnerable to SQL Injection and other security problems. Instead of using the latest third-party frameworks, language for website development, and version database server, another factor to disturb the services of a web server may be the socket programming for sensors at the production level. These sensors are installed in vehicles to track or use them for booking mobile apps.
