Learning PowerShell is a custom-built, handcrafted, painstakingly curated book designed to get you from total PowerShell newbie to confident PowerShell user in as little as four weeks. This book assumes no prior knowledge, perfect for non-developers and GUI addicts who recognize that PowerShell is the future but need a good bit of handholding to achieve mastery. It is also a simple guide for the hundreds of thousands of PowerShell users who have not attained the level of PowerShell knowledge that they really need. With Learning PowerShell at your side, you will see that you don't have to be a developer to use PowerShell and you don't need to be a scripting wizard to derive value from integrating PowerShell into your daily administrative activities. The book is a learning resource that covers every topic worth discussing for a PowerShell beginner, with a depth of explanation unparalleled by any book currently on the market. With this book, you don't have to have a lot of time to learn the language and you can begin applying what you master almost immediately. Even skeptics of PowerShell, and command lines in general, will come away with a renewed sense of respect for the language and ideas on how to put it to use.

In this paper, we present six new contributions: two novel definitions and four groundbreaking theorems related to the theoretical foundations of the integral T e transform, with a specific focus on analyzing functions with integrable modulus. The definitions referred to the T e window and the T e transform in two parameters, respectively. The theorems provide the main theoretical basis for the T e transform: the existence of the T e transform in two parameters, the T e transform ∈ L 1( R ) , the existence of the inverse T e transform, and uniqueness of the T e transform. These results reveal the importance of the fact that the T e transform only depends on two parameters (translation and dyadic frequency), obtaining its inverse transformation more directly; hence, breaking through a new approach in function analysis by representing a function in the scale-frequency plane. The theoretical results presented in this paper are supported by the previous works of the authors.

We present here \"Just Another Tool for Online Studies\" (JATOS): an open source, cross-platform web application with a graphical user interface (GUI) that greatly simplifies setting up and communicating with a web server to host online studies that are written in JavaScript. JATOS is easy to install in all three major platforms (Microsoft Windows, Mac OS X, and Linux), and seamlessly pairs with a database for secure data storage. It can be installed on a server or locally, allowing researchers to try the application and feasibility of their studies within a browser environment, before engaging in setting up a server. All communication with the JATOS server takes place via a GUI (with no need to use a command line interface), making JATOS an especially accessible tool for researchers without a strong IT background. We describe JATOS' main features and implementation and provide a detailed tutorial along with example studies to help interested researchers to set up their online studies. JATOS can be found under the Internet address: www.jatos.org.

Conducting research via the Internet is a formidable and ever-increasingly popular option for behavioral scientists. However, it is widely acknowledged that web-browsers are not optimized for research: In particular, the timing of display changes (e.g., a stimulus appearing on the screen), still leaves room for improvement. So far, the typically recommended best (or least bad) timing method has been a single requestAnimationFrame  (RAF) JavaScript function call within which one would give the display command and obtain the time of that display change. In our Study 1, we assessed two alternatives: Calling the RAF twice consecutively, or calling the RAF during a continually ongoing independent loop of recursive RAF calls. While the former has shown little or no improvement as compared to single RAF calls, with the latter we significantly and substantially improved overall precision, and achieved practically faultless precision in most practical cases. Our two basic methods for effecting display changes, plain text change and canvas  color filling, proved equally efficient. In Study 2, we reassessed the “RAF loop” timing method with image elements in combination with three different display methods: We found that the precision remained high when using either visibility  or opacity  changes – while drawing on a canvas  element consistently led to comparatively lower precision. We recommend the “RAF loop” display timing method for improved precision in future studies, and visibility  or opacity  changes when using image stimuli. We publicly share the easy-to-use code for this method, exactly as employed in our studies.

This contribution outlines a completely new, fully local approach for secure web-based device control on the basis of browser inter-window messaging. Modern smart home IoT (Internet of Things) devices are commonly controlled with proprietary mobile applications via remote servers, which can have significant adverse implications for the end user. Given that many IoT devices in use today are limited in both available memory and processing speed, standard approaches such as HTTPS-based transport security are not always feasible and a need for more suitable alternatives for such constrained devices arises. The proposed local method for lightweight and secure web-based device control using inter-window messaging leverages existing standard web technologies to enable a maximum degree of privacy, choice, and sustainability within the smart home ecosystem. The implemented proof-of-concept shows that it is feasible to meet essential security objectives in a local web IoT control context while utilizing less than a kilobyte of additional memory compared to an unsecured solution, thereby promoting sustainability through hardening of the control protocols used by existing devices with too few resources for implementing standard web cryptography. In this way, the present work contributes to achieving the vision of a fully open and secure local smart home.

This manuscript introduces MPSD (Malicious PowerShell Script Detector), an advanced tool to protect Windows systems from malicious PowerShell commands and scripts commonly used in fileless malware attacks. These scripts are often hidden in Office document macros or downloaded remotely via PowerShell, posing significant threats to corporate networks. A 2018 report revealed that 77% of successful cyberattacks involved fileless malware, with PowerShell being the primary attack method, as highlighted in Red Canary’s 2022 report. To counter these threats, MPSD leverages the Antimalware Scan Interface (AMSI) to intercept and analyze real-time PowerShell scripts, preventing their execution. It further utilizes VirusTotal to filter out malicious scripts. Unlike traditional methods that rely on direct access to scripts, MPSD detects them before execution, addressing the challenge of hidden or obfuscated scripts. Experimental results show that MPSD outperforms well-known antivirus engines, with a low false-negative rate of 1.83%. MPSD is highly effective against evasion techniques like concatenation, encoding, and reordering, making it a robust tool in the cybersecurity landscape.

In this paper, we present ParVis , an interactive visual system for the animated visualization of logged parser trace executions. The system allows a parser implementer to create a visualizer for generated parsers by simply defining a JavaScript module that maps each logged parser instruction into a set of events driving the visual system interface. The result is a set of interacting graphical/text windows that allows users to explore logged parser executions and helps them to have a complete understanding of how the parser behaves during its execution on a given input. We used our system to visualize the behavior of textual as well as visual parsers and describe here two of these uses. Moreover, in order to validate the efficacy of our system, we ran a user experiment where students analyzed a CUP-generated parser both with ParVis , instantiated to LALR parsers, and the standard CUP debug facilities. The results show that students can indeed analyze parser behavior and find mistakes in parser specifications more easily and quickly using ParVis . In particular, in some parser design tasks, using ParVis participants achieved a higher success rate of 50 % in 42 % less time with respect to the baseline system.

The objective of this study is to provide innovative model for the approach of language preservation. It is necessary to maintain indigenous languages in order to avoid language death. Script applications for indigenous languages are one of the solutions being pursued. This script program will facilitate communication through writing between speakers of indigenous languages. Additionally, the study illustrates the implementation of the Lontara script (Bugis-Makassar local language letters and characters). This script application is compatible with the Microsoft Windows operating system and the Hypertext Transfer Protocol (HTTP). This study employed the research and development (R&D) approach. Six stages are followed in this R & D study: 1) doing a requirements analysis to determine the viability of Bugis-Makassar indigenous languages in everyday life and also to determine ways to retain them 2) designing and constructing Lontara scripts with hypertext-based applications, 3) producing Lontara scripts with hypertext-based applications, and 4) validating the hypertext-based applications through one-to-one testing, small and large group testing. 5) Lontara application revision; and 6) Lontara application as a finished product. This product is designed to be used in conjunction with other interactive applications.

The newly updated inventory of palaeoecological research in Latin America offers an important overview of sites available for multi-proxy and multi-site purposes. From the collected literature supporting this inventory, we collected all available age model metadata to create a chronological database of 5116 control points (e.g. 14C, tephra, fission track, OSL, 210Pb) from 1097 pollen records. Based on this literature review, we present a summary of chronological dating and reporting in the Neotropics. Difficulties and recommendations for chronology reporting are discussed. Furthermore, for 234 pollen records in northwest South America, a classification system for age uncertainties is implemented based on chronologies generated with updated calibration curves. With these outcomes age models are produced for those sites without an existing chronology, alternative age models are provided for researchers interested in comparing the effects of different calibration curves and age–depth modelling software, and the importance of uncertainty assessments of chronologies is highlighted. Sample resolution and temporal uncertainty of ages are discussed for different time windows, focusing on events relevant for research on centennial- to millennial-scale climate variability. All age models and developed R scripts are publicly available through figshare, including a manual to use the scripts.

Software testing by using open source tool like Selenium windows applications cannot be automated, citrix based applications, flash websites and games. Computer vision based automation tools can be used to automate these kinds of applications.  These automation tools works based on screenshots of GUI objects like button, radio button, text box, images, dropdowns etc. In this paper a prototype of automation tool has been developed which can execute the automation scripts much faster than existing tools like Sikuli, which takes much time to run the Automation scripts. The execution time can be reduced by using this proposed tool.
