AWS open source newsletter April th Instalment WelcomeHello and welcome to the AWS open source newsletter an Easter special This week sees more great new projects including redshift test drive a set of essential tools for Amazon Redshift users simple database archival solution a nice tool to help you archive your data attribution gen a Go tool to help you build open source attribution documents aws glue data catalog federation a library to help you federate your Glue catalog subnet utilization monitor for amazon vpc a handy tool to keep on top of your IP address allocation AlexaGPT a demo of integrating Alexa with you know what and more We also have some great posts covering your favourite open source projects which this week include Swift Apache Airflow Kubernetes OpenSearch AWS Controllers for Kubernetes Redis Prometheus AWS SAM Terraform Streamlit Steampipe Grafana and more FeedbackPlease please please take minute to complete this short survey and bask in the warmth of having helped improve how we support open source Celebrating open source contributorsThe articles and projects shared in this newsletter are only possible thanks to the many contributors in open source I would like to shout out and thank those folks who really do power open source and enable us all to learn and build on top of what they have created So thank you to the following open source heroes Isaac Levin Sebastien Stormacq Elamaran Shanmugam Aaron Stuyvenberg Sheetal Joshi Liwen Wu Alejandro Molina Anandhi Bumstead Nicholas Knize Bill Beckler Kris Freedain Daniel dB Doubrovkine Shubham Shah Marcin Sodkiewicz Emre Yılmaz and Mukesh Murugan Latest open source projectsThe great thing about open source projects is that you can review the source code If you like the look of these projects make sure you that take a look at the code and if it is useful to you get in touch with the maintainer to provide feedback suggestions or even submit a contribution Toolssimple database archival solutionsimple database archival solution s an open source solution which you can deploy in your AWS account to archive data to AWS SDAS will connect to your database which can be on premises or in the cloud map the schema perform validation and finally transfer data to AWS for storage in Amazon S This is accomplished by primarily leveraging AWS Step Functions and AWS Glue The main purpose of SDAS is to provide an out of the box solution that easily allows customers to archive data in the cloud coming from on premises or cloud hosted databases redshift test driveredshift test drive is an amalgamation of a number of useful Redshift tools These consists of Workload Replicator Replay Analysis External Object Replicator and Node Config Customers are always trying to reproduce issues or workloads from clusters or to do what if scenarios A customer can easily clone a production cluster but replicating the workload is more complicated Workload Replicator was created to bridge that gap working together with Replay Analysis External Object Replicator replicates COPY commands objects Copy manifest objects and Spectrum objects in source cluster to the target s location Finally Node Configuration Comparison utility answers a very common question on which instance type and number of nodes should we choose for your workload on Amazon Redshift Each tool has a separate and detailed README to help you get started attribution genattribution gen is a useful tool for Go developers and helps you generate license attributions files Currently it only works with Go projects using modules As the README states We hope you find this tool useful please verify the accuracy of the detected third party code and licenses aws glue data catalog federationaws glue data catalog federation enables you to link your external metastores to AWS Glue Data Catalog This eliminates the need to migrate your metastore into the AWS Glue Data Catalog in order to leverage other AWS services such as AWS Lake Formation Amazon Athena Amazon Redshift amp Amazon EMR These are open source base implementations of federation connectors These connectors provide the necessary translation layer between AWS Glue Data Catalog and your external metastore Currently the only support external federation to the Apache Hive Metastore subnet utilization monitor for amazon vpcsubnet utilization monitor for amazon vpc This sample deploys a Lambda function that monitors IPv utilisation for Amazon VPC Subnets and published the metrics to CloudWatch as custom metrics It provides metrics around the number of available IPv IPs Total IPs Used IPs and IP utilisation Check out the README for more info The tool is easily deployed via a CloudFormation template AlexaGPTAlexaGPT is a project for those of you who

Learn Open Closed Principle in C# (+ Examples) |

Learn Open Closed Principle in C Examples The Open Closed Principle OCP is a core tenet of the SOLID principles in object oriented programming By understanding and applying the OCP in C developers can create maintainable scalable and flexible software systems This article will discuss the Open Closed Principle in C provide examples and share best practices to help developers craft clean and robust code Defining the Open Closed Principle OCP The Open Closed Principle introduced by Bertrand Meyer states that software entities such as classes modules and functions should be open for extension but closed for modification In other words developers should be able to add new functionality to a class without changing its existing implementation This can be achieved through abstraction inheritance and polymorphism Why is the Open Closed Principle Important Adhering to the OCP promotes a more maintainable flexible and scalable codebase By ensuring that classes are open for extension and closed for modification developers can add new functionality without altering existing code minimizing the risk of introducing bugs or breaking existing features This principle encourages the use of abstractions and promotes a modular architecture that is easier to understand test and refactor Open Closed Principle in C Key ConceptsTo understand the OCP in C let s explore some key concepts AbstractionAbstraction is a technique that allows developers to hide the internal implementation details of a class and expose only its essential features By using abstraction developers can create flexible and extensible designs that are less susceptible to change Inheritance and PolymorphismInheritance is a mechanism in C that allows one class to inherit the properties and methods of another class while polymorphism enables a class to have multiple implementations based on the context These concepts play a crucial role in achieving the Open Closed Principle as they allow developers to extend classes without modifying their existing implementation Open Closed Principle C ExampleLet s consider an example to demonstrate the Open Closed Principle in C Suppose we have a Shape class and a AreaCalculator class that calculates the area of different shapes public class Shape public double Width get set public double Height get set public class AreaCalculator public double CalculateArea Shape shape return shape Width shape Height In this example the AreaCalculator class can only calculate the area of rectangles If we want to add support for other shapes such as circles and triangles we would need to modify the existing implementation of the AreaCalculator class which violates the Open Closed Principle To adhere to the OCP we can use abstraction and inheritance to create separate classes for each shape type and provide a consistent method for calculating the area public abstract class Shape public abstract double CalculateArea public class Rectangle Shape public double Width get set public double Height get set public override double CalculateArea return Width Height public class Circle Shape public double Radius get set public override double CalculateArea return Math PI Math Pow Radius public class AreaCalculator public double CalculateArea Shape shape return shape CalculateArea Now the AreaCalculator class adheres to the Open Closed Principle as it can support new shapes without modifying its existing implementation Strategies for Implementing the Open Closed Principle in CHere are some strategies to help implement the Open Closed Principle in C Using Abstract ClassesAbstract classes can be used to define a base class with common functionality and provide a consistent interface for derived classes By creating abstract methods developers can enforce that each derived class implements its own version of the method allowing for extensibility without modifying the base class Leveraging InterfacesInterfaces in C can be used to define a contract that classes must adhere to By implementing interfaces developers can create flexible designs that can be easily extended and modified without affecting existing implementations Applying the Strategy PatternThe Strategy Pattern is a behavioral design pattern that enables selecting an algorithm at runtime It can be used to implement the Open Closed Principle by encapsulating different algorithms within separate classes and providing a common interface for them OCP Best PracticesTo ensure adherence to the Open Closed Principle follow these best practices Use abstraction and inheritance to create extensible designs Leverage interfaces to define flexible contracts Encapsulate varying behavior using design patterns such as the Strategy Pattern Open Closed Principle and Other SOLID PrinciplesThe Open Closed Principle is an integral part of the SOLID principles ensuring that software entities are open for extension and closed for modification Adhering to the OCP often goes hand in hand with following the other SOLID principles resulting in a maintainable and flexible codebase Real World Applications of the Open Closed PrincipleApplying the Open Closed Principle in real world scenarios can lead to cleaner more maintainable software systems For example when designing a payment processing system adhering to the OCP helps evelopers easily add support for new payment methods without altering existing code By creating an abstract Shape class or an IShape interface new payment methods can be added as separate classes ensuring that the core payment processing logic remains unchanged and adheres to the OCP ConclusionThe Open Closed Principle is a fundamental concept in object oriented programming and a core tenet of the SOLID principles By adhering to the OCP in C developers can create maintainable scalable and flexible software systems that are easier to extend and modify By understanding key concepts such as abstraction inheritance and polymorphism and following best practices for implementing the Open Closed Principle developers can craft clean and robust code that stands the test of time |
