We are organizing a dev talk on "Extension Functions In Depth", Where will learn about What is #kotlin class, extension functions, how to create one, how it looks in java language and etc.
In this PDF you can learn about Kotlin Basic as well as Intermediate part. As also you can develop the android apps and publish in a google play store.
Slides from a talk and live-coding session about Koin, a pragmatic and lightweight Dependency Injection framework for Kotlin. This talk was given at Auckland Android Community on Dec 5.
https://www.meetup.com/Android-Meetup/events/256734688/
Learn about the basic fundamentals of java and important for the different company's interview. Topics like JRE, JDK, Java Keywords, Primitive DataTypes, Types of Variables, Logical, Shift and Bitwise Operator working, Command Line Argument, Handling Arrays, Array Copy, and different programs and output based programs.
The document discusses dependency injection and declarative services in OSGi. It provides an overview of different implementations of dependency injection in OSGi including Declarative Services, iPOJO, Spring DM, and Peaberry. It then focuses on Declarative Services version 1.0 and 1.1, describing the component lifecycle, configuration, and use of XML descriptors and annotations. Key upcoming changes in version 1.1 include more flexible component lifecycle method signatures and support for private properties.
1. The document discusses functions in Python, including built-in functions, user-defined functions, and anonymous functions. It provides examples of functions with different parameters and return values.
2. It explains the differences between local and global variables and functions. Local variables exist only within their function, while global variables can be accessed from anywhere.
3. The document also summarizes mutable and immutable objects in Python. Immutable objects like strings and tuples cannot be modified, while mutable objects like lists can change.
The document provides an introduction to the Python programming language. It discusses what Python is, its creator Guido van Rossum, and how to write a simple "Hello World" program. It also covers Python data types, operators, flow control using conditionals and loops, functions, input/output operations, and the Zen of Python philosophy guiding Python's design. The document serves as the first day of instruction in a Python course.
This document summarizes a presentation about Kotlin features for Android development. It discusses Kotlin's concise syntax, null safety, lambdas, extension functions, and higher-order functions. It also covers Kotlin collections, coroutines, Anko for layouts and SQLite, and migrating existing Android projects to Kotlin. The presentation provides code examples for many of these features and recommends additional Kotlin learning resources.
This talk presents the simple yet powerful way of dependency injection as defined by the OSGi Compendium Declarative Services specification. Besides covering the basics of Declarative Services this talk also explains the many useful additions of the Declarative Services 1.1 in OSGi R 4.2.

The document discusses dependency injection in OSGi environments. It describes several implementations of dependency injection for OSGi including Declarative Services, Apache Felix Dependency Manager, OSGi Declarative Services, Apache Felix iPOJO, Spring DM, and Peaberry. It provides details on Declarative Services versions 1.0 and 1.1, including their use of XML descriptors and annotations for component configuration and lifecycle management.
Attributes allow flexibility in C# by extending metadata. Common built-in attributes include Obsolete, DllImport, and Conditional. Custom attributes can be created by defining attribute classes. .NET components are executable code known as assemblies. Reflection allows reading metadata from assemblies, including attribute information.
This document summarizes several proposed changes for Java 7 including better integer literals with underscores for clarity, improved type inference for constructors and argument positions, new features like string switches and automatic resource management, and new libraries such as NIO2 and the fork/join framework for parallel programming.
The document provides information about various Python concepts like PEP 8, pickling, lambda functions, generators, modules, packages and more. It also includes questions about memory management in Python, tools for static analysis, decorators, iterators, slicing, and other common Python interview questions.
The document discusses operator overloading in Kotlin using the example of a Coin enum and Wallet class. It defines a Coin enum with values for common coins (PENNY, NICKEL, etc) that each have a cents value. A Wallet class is defined with a plusAssign operator function that allows adding Coin values to the wallet amount. Examples are shown incrementing a wallet variable by adding Coin values like QUARTER to demonstrate operator overloading.
This document discusses Express.js, a popular Node.js web application framework. It begins by explaining that Express makes developing websites, web apps, and APIs easier by providing route support and templating engine integration. It then demonstrates how to install Express and a templating engine like Jade. Several code examples are provided, including creating a simple REST API with routes, using Express to serve multiple pages with query parameters, and building a RESTful API for a resource like dogs. Resources for further learning about Express and Node.js are listed at the end.
The Ring programming language version 1.4 book - Part 3 of 30Mahmoud Samir Fayed
This document summarizes the new features and changes in Ring 1.4. It describes improvements to the Ring Notepad including using QPlainTextEdit, displaying line numbers, and auto-complete functions. It also discusses new features for the Emacs editor, updated standard library functions, changes to the Loop|Exit command, and new functions like PackageName() and Swap(). Additional sections cover classes returning by reference, using < and : operators as 'from', embedding Ring code without shared state, the new RingZip library, and the included Form Designer.
1. Inline functions are small functions whose code is inserted at the call site instead of generating a function call. This avoids overhead of function calls but increases code size.
2. Function overloading allows different functions to have the same name but different parameters. The compiler determines which version to call based on argument types.
3. C++ classes allow defining data types that bundle together data members and member functions that can access them. Classes support data hiding and inheritance.
Kotlin Advanced - language reference for Android developers STX Next
StxNext Lightning Talks - Mar 11, 2016
This presentation contains the second talk on Kotlin language we had at STXNext. We try go deeper into language specifics and look at the positive impact new syntax can have on boilerplate removal and readability improvement.
Kotlin really shines in Android development when one looks at “Enum translation”, “Extension functions”, “SAM conversions”, “Infix notation”, “Closures” and “Fluent interfaces” applied to lists. The talk, however, compares language-specifics of Java & Kotlin in terms of “Type Variance”, “Generics” and “IDE tools” as well.
We present real-world example based on Stx-Insider project written in Kotlin which incorporates Dagger 2, Kotterknife, Retrofit2 and is composed of 5+ Activities.

Sébastien Deleuze, Pivotal
"In this new talk, I will explain why Spring <3 Kotlin and how you can leverage Spring official support for Kotlin (in Framework, Boot, Data) to build your next Spring project more efficiently and with more pleasure.
I will describe gradually how you can transform your Spring Boot 1.0 Java + Javascript project with into a Spring Boot 2.0 pure Kotlin project running on top of the new WebFlux functional web framework."
Kotlin is a statically typed programming language that runs on the Java Virtual Machine and is fully interoperable with Java. It was developed by JetBrains as an alternative to Java for Android development, with improvements like null safety, lambdas, and concise syntax. Kotlin aims to be a safer language than Java by eliminating NullPointerExceptions and adding features like data classes, extensions, and higher-order functions. These features allow for more readable, concise code compared to Java.
C++ (pronounced "see plus plus") is a computer programming language based on C. It was created for writing programs for many different purposes. In the 1990s, C++ became one of the most used programming languages in the world.
The C++ programming language was developed by Bjarne Stroustrup at Bell Labs in the 1980s, and was originally named "C with classes". The language was planned as an improvement on the C programming language, adding features based on object-oriented programming. Step by step, a lot of advanced features were added to the language, like operator overloading, exception handling and templates.
C++ is an object-oriented programming language created by Bjarne Stroustrup in 1985 that maintains aspects of C while adding object-oriented features like classes. C++ can be used to create small programs or large applications across many domains. Key concepts covered include functions, classes, inheritance, polymorphism, and memory management techniques like realloc() and free().
This document provides an overview of Java programming concepts covered in a course. It discusses:
- Sections of the course covering topics like Applets, Multithreading, AWT, Swing, Networking and JDBC.
- A brief history of Java and its versions.
- Core Java concepts like objects, classes, inheritance, interfaces, strings and exceptions.
- Other features like being platform independent, secure, robust and portable.
- Data types, operators, methods, constructors, access modifiers and this keyword in Java.
The key difference between Java and Kotlin is given with details. Java is great and highly accepted across platforms, but its getting old.
Why is Kotlin taking so much preference and why should one prefer Kotlin? All the details are explained here.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
