Kotlin For Android (at DevFest İzmir 2016)

Rust is a multi-paradigm systems programming language that offers a blend of speed, safety, and concurrency. It uses a borrow checker to eliminate data races and memory leaks. The presentation introduces Rust's syntax, features like ownership and borrowing, and demonstrates its poker hands and borrow checker examples. Potential downsides discussed are long build times and lack of developers, but Rust aims to prevent common issues like null pointers and shooting yourself in the foot.

How to generate JAR file dynamically compiling Java code in Kotlin

Mitsunori Komatsu

This document discusses how to dynamically generate a JAR file by compiling Java code in Kotlin. It involves converting a Lisp AST to Java source code using a visitor pattern, compiling the Java code with Janino, extracting the Java bytecode using reflection, and creating a JAR file from the bytecode and dependent classes. Key steps include traversing the Lisp tree to generate Java source, using Janino to compile the source in-memory, accessing Janino's hidden bytecode field to obtain the bytecode, and packaging the bytecode and dependencies into a JAR file.

MongoDB World 2018: A Swift Introduction to Swift

MongoDB

Swift is a new programming language released by Apple in 2014 that is designed to be safer, more modern, and work seamlessly with Objective-C. The document discusses building a MongoDB driver in Swift, highlighting some of Swift's key features like protocols, extensions, generics, and optionals that make it well-suited for this task. Interfacing Swift with existing C-based MongoDB drivers also presents challenges around representing BSON data types and pointer types that the driver had to address. Future work on the driver includes implementing more of the MongoDB API and taking advantage of newer Swift features.

Our wish to Flowtype

Teppei Sato

This document summarizes a talk given about Flowtype, a static type checker for JavaScript. The talk discussed how Flowtype allows for strong type inference in React.js projects, checks propTypes statically, and is fast. While Flowtype is not a language itself and just a type checker, its type annotations use a colon instead of TypeScript's angle brackets. The speaker was eager for Flowtype's continued development, as its documentation and support for contributing were still incomplete.

Isomorphic Kotlin

Benjamin Snider

Isomorphism: the Holy Grail of code reuse. Is Kotlin up to the task? What do we even mean when we say isomorphism? We walk through the current state of the art with Kotlin, showcasing Kotlin's capabilities to run on targets such as iOS, Android, Web, and Server platforms. As well, we'll cover other approaches and platforms that promise similar code reuse. We'll take a detour and look at Kotlin/Native, comparing and contrasting it's approach. Along the way, we'll also explore some application architectures that make the most of shared code modules. In the end, we make an informed decision: is isomorphic Kotlin wired or tired?

Kotlin Multiplatfom In Action

Marko Mitic

This document discusses why and how to share code across platforms using Kotlin Multiplatform. It notes that sharing code can increase productivity by reducing duplicated code and bugs, while allowing apps to share features and business logic. However, performance may decrease and innovation could slow if too much code is shared. Kotlin Multiplatform allows writing code once that can run natively on multiple platforms, while each platform still gets optimized binaries and access to native APIs. It provides optional code sharing without limiting developers to a subset of platforms or requiring shared UIs.

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.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM

HODECEDSIET

Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems. ### How TDM Works 1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal. 2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned. 3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver. 4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots. ### Types of TDM 1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data. 2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel. ### Applications of TDM - **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot. - **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth. - **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium. ### Advantages of TDM - **Efficient Use of Bandwidth**: TDM all

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

gerogepatton

As digital technology becomes more deeply embedded in power systems, protecting the communication networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3) represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities. Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network (CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to train and test our model. The results of our experiments show that our CNN-LSTM method is much better at finding smart grid intrusions than other deep learning algorithms used for classification. In addition, our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection accuracy rate of 99.50%.
