Dart is a programming language mainly backed by Google and developed with open source community. It is a client-optimized programming language for developing high-performance apps on multi-platform, such as mobile, desktop, web, and server. Dart was unveiled at the GOTO conference in Aarhus, Denmark, October 10–12, 2011. Long story short, during the keynote of Google Developer Days in Shanghai in September 2018, Google announced Flutter Release Preview 2, the last major release before Flutter 1.0. Until now, Flutter 3 and Dart 3 stable releases has been unveiled and performing very well both on market share and performance compared to other hybrid/cross-platform framework competitors.

Developing software by teams which adopted the agile development methodology such as Scrum seems totally natural in industry. On the other hand, students belonging to graduate schools of information science who have some experience on the agile team software development are rare. In the initial education on the Scrum, there exists some challenges. The first one is a concept of self-organization. In the Scrum project, members of the team determine how best to accomplish the tasks by themselves. However, it is challenging for students with less experience on team software development to cultivate the self-organizing team by themselves. The 2nd one is inequality on task assignment. In the Scrum project, each member pulls tasks to perform, and do not wait to be assigned by Project Manager. The assignment behavior may cause inequality on task assignment. As a result, such inequality may also cause inequality on learning opportunities to acquire skills and knowledge on the process and the product. In this paper, we propose quantitative assessment methods for the Scrum project with using TiDD(Ticket Driven Development) for the initial education on the Scrum framework and web application production. We report on our basic PBL(Project-Based Learning) course which involved 49 students. The use of quantitative criteria enabled students and teachers to assess the Scrum projects in the viewpoints of quality, assignment, and delivery of projects. http://dl.acm.org/citation.cfm?id=2591162

The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: java.util.stream and java.util.function. After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created. Session at the IndicThreads.com Confence held in Pune, India on 27-28 Feb 2015 http://www.indicthreads.com http://pune15.indicthreads.com

Flutter is an open-source framework developed by Google for building user interfaces (UI) for mobile, web, and desktop applications from a single source code. It allows developers to quickly create beautiful, responsive applications using the Dart programming language. OOP (Object-Oriented Programming) is a programming paradigm that focuses on organizing and modeling software based on objects that include data and methods that operate on that data. This approach allows developers to create structures that are more organized, modular, and easy to understand. Flutter state management is a way to manage and update state in a Flutter application. In application development, state Refers to data that can change over time, such as user text input, authentication status, or values obtained from API calls.

Convolutional Neural Networks (CNN) for Computer Vision represent a powerful approach in image analysis. The process begins with a comprehensive understanding of Artificial Neural Networks (ANN) as a foundational concept. Data preprocessing plays a crucial role, involving tasks like image normalization and augmentation to enhance model robustness. Leveraging the TensorFlow framework, the model is constructed, encompassing convolutional layers for feature extraction and fully connected layers for classification. Evaluation metrics such as accuracy and loss are employed to assess the model's performance. Finally, deployment involves integrating the trained CNN into real-world applications, ensuring its seamless integration and functionality for image recognition tasks.

The "Introduction to Machine Learning" material covers the fundamental aspects of machine learning and data science through a series of key concepts. Starting with the understanding of data and information, the material elaborates on various types of data and the distinctions between large data, high dimension data, and big data. It encompasses the stages of machine learning, such as Data Preparation, Training, and Testing, providing practical application examples. Terminology such as samples and features is introduced, while metrics like confusion metrics are utilized to evaluate model performance. Concepts like the learning curve, supervised learning, and the differences between classification and regression are also briefly explained. The material also includes basic techniques like cleaning data (handling missing values and duplicates) and data transformation (changing data types). Finally, the concept of data visualization is introduced through examples involving scatter plots, histograms, and other visualizations to enhance understanding and interpretation of data more effectively. Overall, this material establishes a strong foundation for comprehending machine learning concepts and acquiring practical skills in manipulating and analyzing data.
