海外TECH	DEV Community	Automating EC2 Instance Start/Stop using Serverless Code and CloudWatch Rule	https://dev.to/kerisnarendra/automating-ec2-instance-startstop-using-serverless-code-and-cloudwatch-rule-429p	Automating EC Instance Start Stop using Serverless Code and CloudWatch Rule IntroductionIn this blog post I am going to show you how to use serverless and a CloudWatch rule to automate starting and stopping EC instances in AWS This is particularly useful for teams that need to frequently scale up and down their infrastructure We ll also cover the cron syntax used to specify the schedule for the CloudWatch rule including an important limitation to be aware of By automating this process you can save time and reduce costs by only running EC instances when you need them PrerequisitesBefore we get started make sure you have the following An AWS account with permissions to create EC instances CloudWatch rules and Lambda functions An EC instance that you want to start and stop based on a schedule A basic understanding of serverless and the AWS CloudWatch service Step by Step GuideTo create a CloudWatch rule that invokes a Lambda function to start and stop an EC instance using serverless code follow these steps Set up a new serverless project in AWS by running the command serverless create template aws nodejs path ec scheduler Navigate to the ec scheduler folder and open the serverless yml file Under provider add the following lines to allow the Lambda function to start and stop EC instances iam role statements Effect Allow Action ec StartInstances ec StopInstances Resource Under custom add the instance ID of the EC instance you want to start and stop as well as the cron expressions for starting and stopping the instance For example custom instanceId i f start cron MON FRI stop cron MON FRI This will start the instance at AM UTC every Monday through Friday and stop the instance at PM UTC every Monday through Friday The cron expression syntax should conform to the following where all six fields are required and must be separated by a white space cron Minutes Hours Day of Month Month Day of Week Year Each field can have the following values wildcards Notes Make Sure You re Not Using in Both the Day of Month and Day of Week FieldsUnder functions create two functions start and stop These functions will call the startInstances and stopInstances methods of the EC service respectively For example functions start handler handler start events schedule rate self custom start input id self custom instanceId region self provider region stop handler handler stop events schedule rate self custom stop input id self custom instanceId region self provider region Create the handler js file and define the start and stop functions that will be called by the start and stop functions defined in the serverless yml file For example use strict const AWS require aws sdk module exports start event context callback gt const ec new AWS EC region event region ec startInstances InstanceIds event id promise then gt callback null Successfully started event id catch err gt callback err module exports stop event context callback gt const ec new AWS EC region event region ec stopInstances InstanceIds event id promise then gt callback null Successfully stopped event id catch err gt callback err Deploy the project by running the command serverless deploy aws profile aws profile in dot aws folder This will create the CloudWatch rule and Lambda function in your AWS account Once the deployment is complete verify that the CloudWatch rule and Lambda function have been created in the AWS console Test the solution by waiting for the scheduled time to start and stop the EC instance You should see the instance status change in the AWS console FAQQ Can I schedule different start and stop times for different instances A Yes you can modify the custom section of the serverless yaml file to specify different instance IDs and schedules for each instance Q What if the Lambda function fails to start or stop the instance A The Lambda function will return an error message if it fails to start or stop the instance You can view the error message in the AWS console or in the CloudWatch logs Q Can I use this solution with other AWS services besides EC instances A Yes you can modify the Lambda function code to interact with other AWS services ReferencesIf your aws account is using mfa check if the cron expression syntax and values are correct ConclusionAutomating the start and stop of EC instances based on a schedule can help you save time and reduce costs by only running instances when they are needed Using serverless code and a CloudWatch rule makes it easy to implement this solution in your AWS account With this solution in place you can focus on other important tasks while your infrastructure scales up and down automatically	2023-05-12 04:47:00
海外TECH	DEV Community	Using useReducer and Redux Toolkit Together: A Powerful Combination for State Management	https://dev.to/sathishskdev/using-usereducer-and-redux-toolkit-together-a-powerful-combination-for-state-management-3b2h	Using useReducer and Redux Toolkit Together A Powerful Combination for State ManagementDevelopers may hesitate to use useReducer in React because it requires a different approach to managing state than the more familiar useState hook While useState provides a simple way to manage state within a component it can become unwieldy for more complex state management needs While useReducer can be more efficient than useState it requires additional boilerplate code to set up the reducer function and manage state updates Redux Toolkit provides a more modern and user friendly approach to managing state in your React application with a simpler API better performance and fewer bugs It is a great option for developers who want to take advantage of the benefits of Redux while minimising the complexity and boilerplate code that comes with traditional Redux If you re using useReducer in your React application you may be missing out on the full potential of Redux Toolkit s powerful API With features createSlice Manage creating reducer creating action and state Redux Toolkit streamlines the process of managing state in your app reducing the need for writing custom reducers and actions by hand A Practical Example with useReducerLet s take an example of good old fashioned Todo app In this example We need below boiler plates for managing tasks Action TypesActionsReducer We no longer need this boilerplate code in useReducerWe will add redux toolkit in this app It provides a createSlice function that generates useReducers reducers action creators and action types in a concise manner This simplifies the process of defining and managing state in useReducer Creating reducersBy defining the initialState within the slice file useToolKitReducer js We centralize the initial state configuration alongside the corresponding reducer logic Adding reducer to the componentWe can get initial state reducer and actions from this useToolKitReducer slice Redux Toolkit utilizes the immer library internally enabling you to write code that appears to mutate state directly within the reducers Under the hood immer ensures immutability by producing new immutable states This simplifies the process of updating state and avoids common pitfalls associated with manual immutability handling Avoiding manual dispatch actions and bindingWe can use bindActionCreators to avoid manually dispatching actions and binding them to the dispatch function in your components It simplifies the process and provides a convenient way to use action creators directly as functions abstracting away the details of dispatching actions in our component code Using Action Creator as functionsNow we can use these action creators as functions in our component No need to manually wrap dispatch in action creators The Benefits of combining useReducer and Redux Toolkit Minimize Configuration Overhead and Save Time Streamlined state management Built in immutability immer and ease of updates Improve maintainability of our codebase For improve maintainability further you can check our blog Separation of concerns in React and React Native Sathish Kumar N・May ・ min read react bestpractice designpatterns modularity Please give your feedback and questions on comments section Happy Coding	2023-05-12 04:06:44
海外TECH	DEV Community	Working with Rust as a C++ Programmer	https://dev.to/malwarebo/working-with-rust-as-a-c-programmer-1af8	Working with Rust as a C ProgrammerRust is a modern programming language that is quickly gaining popularity It is known for its safety speed and expressiveness Many C programmers are finding that Rust is a great language to learn as it offers many advantages over C In this post we will discuss the similarities and differences between Rust and C and we will provide some tips for C programmers learning Rust IntroductionRust is a multi paradigm general purpose programming language designed for performance and safety especially safe concurrency Rust is syntactically similar to C but can guarantee memory safety by using a borrow checker to validate references Similarities between Rust and C There are many similarities between Rust and C Both languages are statically typed compiled languages that support object oriented programming Rust also supports many of the same features as C such as pointers arrays and functions Here are some of the similarities between Rust and C Syntax Rust s syntax is very similar to C Both languages use curly braces to group statements and both languages have similar keywords Ownership and borrowing Rust s ownership and borrowing system is similar to C s memory management system In both languages it is important to manage the lifetime of objects carefully to avoid memory leaks Memory management Rust uses a borrow checker to manage memory safety The borrow checker ensures that references to objects are always valid and that objects are never destroyed while they are still in use Generics Rust supports generics which allow you to write code that can be used with different types of data Traits Rust supports traits which are similar to C s interfaces Traits allow you to define a set of methods that a type must implement Function pointers Rust supports function pointers which are similar to C s function pointers Function pointers allow you to pass functions as arguments to other functions Lambdas Rust supports lambdas which are similar to C s lambdas Lambdas allow you to create anonymous functions that can be passed as arguments to other functions Differences between Rust and C There are also some important differences between Rust and C These differences include Safety Rust is a much safer language than C Rust s borrow checker ensures that references to objects are always valid and that objects are never destroyed while they are still in use This helps to prevent many common programming errors such as dangling pointers and memory leaks Concurrency Rust has a very powerful concurrency model that is designed to be safe and easy to use Rust s concurrency model is based on the concept of ownership and borrowing This allows you to write concurrent code that is safe and easy to understand Modules Rust s modules system is much more powerful than C s namespace system Rust s modules system allows you to organize your code into logical units and it makes it easy to import and export symbols from different modules Cargo Rust has a build system called Cargo that makes it easy to manage Rust projects Cargo can automatically download and build dependencies and it can also publish your projects to crates io which is a central repository for Rust crates C programmers learning RustIf you are a C programmer who is interested in learning Rust here are some tips Focus on the similarities first Rust and C have many similarities so it is helpful to focus on these similarities when you are first learning Rust Don t try to learn everything at once Rust is a complex language so it is important to take your time and learn one thing at a time Use the Rustonomicon as a reference The Rustonomicon is a comprehensive reference for Rust It is a great resource for learning about Rust s features and syntax Ask for help in the Rust community The Rust community is very welcoming and helpful If you have any questions don t hesitate to ask for help on the Rust subreddit or the Rust forum I hope this post has been helpful If you are a C programmer who is interested in learning Rust I encourage you to give it a try Rust is a powerful and expressive language that can be used for a wide variety of tasks	2023-05-12 04:02:05
