In this 1 hour guided project, you will learn how to use one of the most versatile Linux networking utilities tcpdump to capture and analyze TCP traffic. Popular among all ranks of networking professionals, tcpdump will definitely empower you in daily networking operations. Basic network experience and shell script basics are highly recommended as prerequisites.

By the end of this project, you will Create React Forms Using Hooks. React Hooks were added so that state and lifecycle could be addressed within a React Functional component. This simplifies state and component lifecycle management. This project is for learners who want to gain a good foundation using React Hooks in a React Form to build a web application.

Do you want to know how robots work? Are you interested in robotics as a career? Are you willing to invest the effort to learn fundamental mathematical modeling techniques that are used in all subfields of robotics? If so, then the "Modern Robotics: Mechanics, Planning, and Control" specialization may be for you. This specialization, consisting of six short courses, is serious preparation for serious students who hope to work in the field of robotics or to undertake advanced study. It is not a sampler. In Course 1 of the specialization, Foundations of Robot Motion, you will learn fundamental material regarding robot configurations, for both serial robot mechanisms and robots with closed chains. You will learn about configuration space (C-space), degrees of freedom, C-space topology, implicit and explicit representations of configurations, and holonomic and nonholonomic constraints. You will also learn how to represent spatial velocities and forces as twists and wrenches. This material is at the core of the study of anything that moves (e.g., robots). This course follows the textbook "Modern Robotics: Mechanics, Planning, and Control" (Lynch and Park, Cambridge University Press 2017). You can purchase the book or use the free preprint pdf. You will build on a library of robotics software in the language of your choice (among Python, Mathematica, and MATLAB) and use the free cross-platform robot simulator V-REP, which allows you to work with state-of-the-art robots in the comfort of your own home and with zero financial investment.

In this course, application developers learn how to design and develop cloud-native applications that seamlessly integrate managed services from Google Cloud. Through a combination of presentations, demos, and hands-on labs, participants learn how to apply best practices for application development and use the appropriate Google Cloud storage services for object storage, relational data, caching, and analytics. Learners can choose to complete labs in their favorite language: Node.js, Java, or Python. This is the first course of the Developing Applications with Google Cloud series. After completing this course, enroll in the Securing and Integrating Components of your Application course.

In this 1-hour long project-based course, you will learn how to: - Manage the file requirements to optimise and export a pattern, - Get started with GIMP 2.10 editing tools - Design customised patterns using GIMP 2.10 By the end of this project, you will learn how to use Gimp to create simple customised patterns. You’ll discover how to create different types of patterns, either by drawing simple shapes directly on GIMP or starting from an existing image. In graphic design and visual arts, a pattern is a design in which the same shape is repeated at regular intervals over a surface. Patterns are used to customise fabrics, prints, wallpaper, gift papers, and any kind of surface your imagination can reach. GIMP version 2.10 is a cross-platform image editor available for many of the most popular operating systems. It is largely used by graphic designers, illustrators, artists, or photographers as an open-source alternative to image editing software. Its interface is user-friendly so it can be enjoyed by anyone interested or involved in jobs related to graphics and visual arts. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

This course extends object-oriented analysis and design by incorporating design patterns to create interactive applications. Through a survey of established design patterns, you will gain a foundation for more complex software applications. Finally, you will identify problematic software designs by referencing a catalog of code smells. You will be challenged in the Capstone Project to redesign an existing Java-based Android application to implement a combination of design patterns. You will also critique a given Java codebase for code smells. After completing this course, you will be able to: • Demonstrate how to use design patterns to address user interface design issues. • Identify the most suitable design pattern to address a given application design problem. • Apply design principles (e.g., open-closed, dependency inversion, least knowledge). • Critique code by identifying and refactoring anti-patterns. • Apply the model-view-controller architectural pattern.

This Course is the first of a series of courses that make up the Core Java Specialization. The Core Java Specialization, in turn, is part of a series of programming specializations, derived from LearnQuest's private Java Bootcamps, designed to provide the skill set necessary to be hired as an IT developer using Java in many corporate environments. This course includes hands-on practice and will give you a solid knowledge of the Java language. After completing this course, you will be able to identify Java’s benefits, program in basic Java syntax using Java data types, and incorporate branches and loops. The audience for this course: - Anyone interested in learning Java - Programmers - Technical Managers - Application Developers Prerequisites: To be successful with this course, you should understand the fundamentals of software development in either a procedural or object-oriented language.

In this course, you learn how to secure your APIs. You explore the security concerns you will encounter for your APIs. You learn about OAuth, the primary authorization method for REST APIs. You will learn about JSON Web Tokens (JWTs) and federated security. You also learn about securing against malicious requests, safely sending requests across a public network, and how to secure your data for users of Apigee. Through a combination of lectures, hands-on labs, and supplemental materials, you will learn how to design, build, secure, deploy, and manage API solutions using Google Cloud's Apigee API Platform. This is the second course of the Developing APIs with Google Cloud's Apigee API Platform series. After completing this course, enroll in the API Development on Google Cloud's Apigee API Platform course.

In the previous course in the Specialization, we learned how to compare genes, proteins, and genomes. One way we can use these methods is in order to construct a "Tree of Life" showing how a large collection of related organisms have evolved over time. In the first half of the course, we will discuss approaches for evolutionary tree construction that have been the subject of some of the most cited scientific papers of all time, and show how they can resolve quandaries from finding the origin of a deadly virus to locating the birthplace of modern humans. In the second half of the course, we will shift gears and examine the old claim that birds evolved from dinosaurs. How can we prove this? In particular, we will examine a result that claimed that peptides harvested from a T. rex fossil closely matched peptides found in chickens. In particular, we will use methods from computational proteomics to ask how we could assess whether this result is valid or due to some form of contamination. Finally, you will learn how to apply popular bioinformatics software tools to reconstruct an evolutionary tree of ebolaviruses and identify the source of the recent Ebola epidemic that caused global headlines.
