海外TECH	DEV Community	Probability for Data Science	https://dev.to/es404020/probability-for-data-science-244e	Probability for Data ScienceProbability is a branch of mathematics that deals with the study of random events and the likelihood of their occurrence It plays a crucial role in our everyday lives from the likelihood of winning the lottery to the probability of a weather forecast being accurate In this article we will explore the basics of probability and provide well detailed examples that anyone can relate to Understanding Probability Probability is a measure of the likelihood of an event occurring It is expressed as a number between and with meaning that the event will never occur and meaning that the event is certain to occur For example the probability of flipping a coin and getting heads is which means that there is an equal chance of getting either heads or tails Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes For example if you roll a six sided die the probability of getting a is because there is only one way to get a and six possible outcomes Well Detailed Examples Rolling Dice Suppose you roll a pair of dice What is the probability of getting a total of To answer this question we need to know how many ways we can get a total of and how many total outcomes are possible There are six ways to get a total of and There are a total of possible outcomes x Therefore the probability of getting a total of is or Flipping Coins Suppose you flip a coin three times What is the probability of getting two heads and one tail To answer this question we need to know how many ways we can get two heads and one tail and how many total outcomes are possible There are three ways to get two heads and one tail HHT HTH and THH There are a total of possible outcomes x x Therefore the probability of getting two heads and one tail is Weather Forecast Suppose you are planning a picnic for next weekend The weather forecast says that there is a chance of rain What is the probability that it will not rain To answer this question we need to subtract the probability of rain from Therefore the probability of not raining is or Conclusion Probability is an essential concept in mathematics that is used in many fields from science and engineering to economics and finance Understanding probability allows us to make informed decisions based on the likelihood of certain events occurring The examples provided in this article are just a few of the many ways that probability can be used in everyday life By applying the principles of probability we can better understand the world around us and make better decisions	2023-04-15 04:40:05
海外TECH	DEV Community	Are you using VS Code Shortcuts?	https://dev.to/crvanetten15/are-you-using-vs-code-shortcuts-592b	Are you using VS Code Shortcuts Overview IntroductionShortcutsTLDR Using the mouse although a valid way to navigate VS Code tends to slow me down Being able to add keyboard shortcuts to your VS Code workflow can improve your coding efficiency IntroductionOne thing as a developer that I believe to be important is efficiency Code efficiency for specific problems is important but so is the speed of code production in our work How fast a programmer is able to produce a file or method can be extremely beneficial For this article I d like to share some ways you might be able to become more efficient within your own development process specifically within Visual Studio Code Within programming there tends to be a negative stigma between developers that use a mouse when editing code and navigating there environment and those who only use a keyboard Now although I don t condone gatekeeping or looking down on other programmers for the way they make there code there seems to be some benefit to using only the keyboard atleast for me The main benefit can be sometimes be seen is performance When using a mouse it can feel like I am taking a break from my normal coding to select an item but it tends to hinder my workflow As I switch between two different motor skills I tend to spend an extra half second or two adjusting to my new peripheral Now this being said I have seen programmers who are able to still maintain a consistent and effortless workflow using both their mouse and keyboard but I feel more often than not it slows me down Now you may be thinking its milliseconds of time and overall it s not a big deal but time does compound over a day It reminds me of the quote A death by a million cuts In this comparison the little cuts are time wasted from using our mouse and although insignificant in the moment they will add up to a more significant amount of time wasted As for me I wanted to make sure that I was more efficient as I developed code within my chosen environment The way I achieved this was through keyboard shortcuts Not having to remove my hand from the keyboard to open windows select files etc has limited the amount of breaks I usually needed to take with my mouse Luckily VS Code comes preloaded with a large amount of premade commands that you can start utilizing now In the next section I will share my used shortcuts to help improve my development speed ShortcutsWindows GuideFor MacOS replace Ctrl with ⌘Show Command PaletteCtrl Shift P or FThis is the command for when you forget all other commands This shortcut opens a menu with all the commands available by search Quick Open Go to FileCtrl PWhen you need to open a new file within your directory this shortcut gives you a menu of all files to select Close EditorCtrl WIf you have finished all development on the file in the current editor window use this shortcut to close that tab Cut LineCtrl XLets say you don t want to keep copying and deleting all your console log s this is the shortcut for you Go to LineCtrl TMore of a specific shortcut but after it is entered you may tell VS Code what line you would like to be redirected to New FileCtrl NOnce the directory is made and opened use this shortcut to make a new file in the current folder Select All Occurrences of SelectionCtrl Shift LEspecially helpful when you want to change all occurrences of a selection Remember hitting ESC will remove the extra cursors Open Integrated TerminalCtrl backquoteFor beginner programmers sometimes the terminal is scary but trust me the more familiar you are with it the better off you are This shortcut will get you there Toggle Sidebar VisibilityCtrl BDefinitely a necessary shortcut for those who have only one screen or work on a laptop Remember this shortcut is a toggle therefore if it is missing this will make it reappear Open Keyboard Shortcut PreferencesCtrl K Ctrl SLastly if you feel that any shortcuts involve the wrong keys for your preference use this shortcut to open preferences and change them Thank you for Reading Feel free to comment if you have any other commands that you use daily that I may have missed Cheers	2023-04-15 04:24:52
海外TECH	DEV Community	Overcoming Front-End Back-End Coupling with AWS Event-Driven Architecture	https://dev.to/marawanxmamdouh/overcoming-front-end-back-end-coupling-with-aws-event-driven-architecture-3ob9	Overcoming Front End Back End Coupling with AWS Event Driven Architecture introductionAs a developer I ve always been interested in event driven architectures EDAs and how they can improve the overall performance and scalability of web applications However I never truly understood the power of EDAs until I faced a real problem with a project I was working on The project was a web application that required real time updates to be displayed on the user interface Users needed to be able to see changes made by other users in real time without having to manually refresh the page Initially I implemented a solution that involved continuously polling the server for updates but this approach was not only resource intensive but it also led to a slow and unresponsive performance It was then that I realized that what I needed was an EDA that would allow me to send real time updates to the front end without continuously polling the server I knew that this would require a lot of work and was unsure where to start That s when I decided to turn to AWS a cloud computing platform that offers a wide range of serverless services including AWS Lambda AWS API Gateway and AWS SNS These services would allow me to build a scalable and efficient EDA that would work seamlessly with my front end application How AWS Serverless Services Helped Me Build an EDAI started by using AWS Lambda a serverless compute service that lets you run your code without provisioning or managing servers With Lambda I could write a function that would be triggered whenever an event occurred I wrote a function that would be triggered whenever a user made a change to the application The function would then send a message to an SNS topic using the AWS SNS service AWS SNS or Simple Notification Service is a fully managed pub sub messaging service that enables you to send messages to multiple recipients at once With SNS I could create a topic and subscribe to all the clients that needed to receive real time updates to that topic Whenever a message was sent to the topic SNS would automatically distribute it to all subscribed clients To connect the front end application to the AWS SNS service I used AWS API Gateway a fully managed service that makes it easy to create deploy and manage APIs at any scale With API Gateway I created an endpoint that would receive messages from the SNS topic and send them to the connected clients using web sockets Benefits of Using AWS Serverless Services to Build EDAsThere are many benefits to using AWS serverless services to build EDAs These benefits include Scalability AWS serverless services are designed to scale automatically with demand This means that you don t have to worry about provisioning or managing servers and you can focus on building your application Reliability AWS serverless services are highly reliable and are designed to be highly available This means that your application will be available even if there are problems with individual servers or regions Cost effectiveness AWS serverless services are very cost effective You only pay for the resources that you use and you don t have to worry about upfront costs or long term commitments The ResultThe result was a highly scalable and efficient EDA that allowed real time updates to be sent to the front end application without continuously polling the server The front end application was now highly responsive and provided an excellent user experience In ConclusionEvent driven architectures have become a crucial aspect of modern web development and using AWS serverless services has made it easier than ever to build highly scalable and efficient EDAs By leveraging services like AWS Lambda AWS SNS and AWS API Gateway developers can build highly responsive and scalable web applications that provide an excellent user experience To those who are considering implementing an EDA I highly recommend exploring AWS serverless services With a little bit of effort and some knowledge of these services you can build highly efficient and scalable EDAs that will take your web development projects to the next level	2023-04-15 04:15:49
