This course teaches you intermediate Linux commands. Linux is a computer system that is widely used in servers and many different devices. If you are a Linux user, you can use the commands in this course to become a pro Linux user. You will learn to filter output, how to use the AWK command, see disk usage and more commands. These should work with any Linux system. Even if you use an online simulator, you should be able to run the commands.grep searches for file patterns. If you're looking for a specific pattern in the output of another command, grep will highlight the relevant lines. Use this command to search log files, specific processes, and more. If you want to see if Apache Tomcat is started, you might be overwhelmed by the number of lines. By piping this output to the grep command, you can isolate the lines that indicate server startup.This course is an intermediate course, you should already have some familiarity with the Linux command line. If you want to learn more about Linux, this is a good course. You will learn some new commands but you should have already used the Linux command line before starting with this course. It doesn't matter if you use Ubuntu, Arch, Debian or any other system.

Svelte is a modern JavaScript framework that stands out for its unique approach to building user interfaces. Unlike traditional frameworks like React or Angular, which use a virtual DOM to update the user interface, Svelte shifts much of the work to compile-time. During this phase, Svelte converts your application into highly optimized vanilla JavaScript code. This innovative approach results in faster runtime performance and smaller bundle sizes, as there's no overhead of a virtual DOM or additional libraries to handle reactivity at runtime.The core philosophy of Svelte is to write less code to achieve more functionality. It introduces a simpler and more intuitive syntax for declaring reactive variables and handling state changes. When a variable changes, Svelte automatically updates the DOM in the most efficient manner. This reactivity is built into the language without the need for additional libraries or tools, making state management straightforward and less error-prone.Svelte's compiler-centric design not only leads to performance benefits but also enhances the developer experience. By handling dependencies and reactivity at compile time, Svelte ensures that only the necessary code is executed, eliminating dead code and reducing the final size of the application. This streamlined process simplifies debugging and speeds up the development cycle.In conclusion, Svelte offers a refreshing and powerful alternative to more traditional JavaScript frameworks. Its compile-time magic, enhanced reactivity system, and leaner final code make it an appealing choice for developers looking to build fast, efficient, and maintainable web applications. As web development continues to evolve, Svelte's innovative approach positions it as a key player in the future of frontend frameworks.

If you are involved or will be involved in data acquisition and control of equipment spread over large geographical areas, then you need to have a working knowledge of the DNP3 protocol. If you work in the areas of Electrical Transmission and Distribution, Water and Waste Water Management, Oil/Gas or Security systems, then having a working knowledge of the DNP3 protocol is a significant asset.This course has been designed with practicality in mind. At the end of this course, you will know how DNP3 devices represent data in memory and the types of messaging that they use to exchange data. You will also perform practical exercises using simulation software, allowing you to get first hand experience in configuring DNP3 devices for communications. Essentially, you will have a new practical skill in the field of SCADA Telemetry and Wide Area Communication. Specifically, in this course, you will learn:- The difference between SCADA and Factory Automation protocols.- How DNP3 devices represent data in memory.- DNP3 network messaging types..- DNP3 terminology: RTU, FIU, Report By Exception, Polled and Unsolicited Communication.- Configuration of settings in DNP3 devices.- Configuration and simulation of DNP3 communication.- Implementation levels and standards.- DNP3 data frame formats.and much more ...

In retail business, retail stores and eCommerce websites generates large amount of data in real-time. There is always a need to process these data in real-time and generate insights which will be used by the business people and they make business decision to increase the sales in the retail market and provide better customer experience. Since the data is huge and coming in real-time, we need to choose the right architecture with scalable storage and computation frameworks/technologies.Hence we want to build the Data Processing Pipeline Using Apache NiFi, Apache Kafka, Apache Spark, Apache Cassandra, MongoDB, Apache Hive and Apache Zeppelin to generate insights out of this data.The Spark Project is built using Apache Spark with Scala and PySpark on Cloudera Hadoop(CDH 6.3) Cluster which is on top of Google Cloud Platform(GCP).Apache Spark is an open-source unified analytics engine for large-scale data processing. Spark provides an interface for programming clusters with implicit data parallelism and fault tolerance.Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds.Apache Hadoop is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. It provides a software framework for distributed storage and processing of big data using the MapReduce programming model.A NoSQL (originally referring to "non-SQL" or "non-relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.

This course is meant for anyone curious about InfoSec and just starting out in this field. Terminology and concepts are explained with the goal of being clear even to those who hear of them for the very first time.The following topics are covered mainly with definitions and theoretical explanations, but also with some practical examples:- The need for InfoSec- CIA Triad (Confidentiality, Integrity, Availability)- Non-repudiation- Risk Assessment Risk Management- Cryptography and it's place in InfoSec- Authentication and Authorization- Governance and Information Security Policies- Security Auditing- Laws Regulations related to Security and Privacy of Data- Security Detection and Response- Vulnerability Management- Security Patching- Penetration TestingAs an experienced Cybersecurity expert, I've changed a few roles and seen different approaches to security, mainly in large corporations. I'm happy to provide insight into how those systems operate, and more importantly, how they're secured. You will learn that it's not all about advanced technology you hear about these days, but also about people, processes, education, and analytical thinking. I truly hope you will find value in these lessons, and feel free to reach out shall you have any questions, suggestions, or ideas to share.Later on, I will add tests in between lessons, including some additional information on differences between all the security disciplines: infosec, cybersec, physical, fraud...
