海外TECH	DEV Community	Use Isolates to prevent ui Jank | Flutter multiprocessing	https://dev.to/ramgendeploy/use-isolates-to-prevent-ui-jank-flutter-multiprocessing-nm8	Use Isolates to prevent ui Jank Flutter multiprocessingAs you might know flutter runs asynchronously on a single thread often called the main thread and also where the UI is running now when you need to run heavy computational function you find that you app freezes and janks because is busy with that function Here is where Isolates come into action this is a way to spawn threads in dart flutter and prevent the main thread to halt Isolates are a little finicky but they are useful when the situation comes and this was the perfect situation I needed to load an image and send it to an API for processing this was janking the main thread but it can be done on an isolate and prevent that Let s see one of the easiest ways of using isolates with the compute function Function to runFirst we need a function to execute this function loads the image and sends it with http to the API Future lt UintList gt requestImg RequestInputs reqInputs async File file File reqInputs filePath final http MultipartRequest request http MultipartRequest POST Uri parse server uri final Map lt String String gt headers lt String String gt Content type multipart form data final img proc Image tmp img proc decodeImage await file readAsBytes final List lt int gt tosend img proc encodeJpg tmp request files add http MultipartFile fromBytes file tosend filename aism source contentType MediaType image jpeg request headers addAll headers request fields addAll reqInputs settings final http StreamedResponse res await request send debugPrint Request settings sent UintList responseImage await res stream toBytes return responseImage Now my function needed more than one argument but the compute function only accepts functions with one to solve this I use a custom class to pass all of the data class RequestInputs final String filePath final Map lt String String gt settings RequestInputs this filePath this externalPath this settings Compute functionGreat we have the function and the custom class let s see how to use compute to run it on an isolate compute lt StickerRequestInputs UintList gt requestImg StickerRequestInputs imgPath storage settings then value gt setState loading false if value null imgBytes value saveImage value else debugPrint Error We first need to declare the function input and output types in the compute statement compute lt Q R gt Q is the input type and R is the return type Then we pass the function and the input to run in this case we instantiate the custom class that we declared The compute is a future of the return type R we can use either async or then to do something after it finishes in this case we update the state with the new data or we print an error if it fails Watch the video for a walkthrough of all the code subscribe to see the progress of the app DAlright and that s it I will continue working with isolates and see what we can do with them but as i said the are a little tricky to work with regardless they are a good option when you need them	2022-08-21 18:38:53
海外TECH	DEV Community	Data Engineering 101: Introduction to Data Engineering	https://dev.to/gathurum/data-engineering-101-introduction-to-data-engineering-5f7f	Data Engineering Introduction to Data EngineeringData Engineering is the process of building data pipelines and making quality data available for efficient data driven decision making A person who performs these activities is called a Data Engineer But what are data pipelines exactly In data processing there is the flow of data from say a point A to B to C i e from an application to a data warehouse or from a data source to the database This series of processing steps is called a data pipeline In these series of steps each step delivers an output that is the input to the next step This continues until the pipeline is complete However in some cases independent steps may be run in parallel What s the difference between a data analyst and a data engineer Data scientists and data analysts analyze data sets to gain knowledge and insights Data engineers on the other hand build systems for collecting validating and preparing that high quality data which is then used by data scientists to promote better business decisions With that said these are some of the Essential skills required to be a Data Engineer in Data StructuresSQLNoSQLUnderstanding of Data Lakes and Data WarehousePythonBig Data Hadoop Apache Spark PySpark Hive and Apache KafkaCloud Services AWS Microsoft Azure Google Cloud Snowflake etc Visualization Tableau PowerBI Looker Qlikview etc I wish you all the best as you choose to pursue this journey Thanks for reading Any questions Leave your comment below to start fantastic discussions	2022-08-21 18:32:46
海外TECH	DEV Community	How much do you need to know before starting?	https://dev.to/noriller/how-much-do-you-need-to-know-before-starting-4o8o	How much do you need to know before starting I was pondering whether you need to know about React Class Components before learning React Functional Components A little background about me I work in an internal department commonly called “shadow IT because it s not part of the official IT This is important to say because most people I ve known came from different backgrounds than that in Computer Science and similar I myself didn t come from a CS background And because of reasons where I work we can t just hire people we have kind of pick people in other areas to come work with us and this usually means people with little to no experience in programming even when they actually want to I ve already put some of my thoughts on this before check my other posts but this time I got into a discussion about whether you need or not to learn React Class Components before learning React Functional components This is an old discussionThis is not about React In the frontend alone we had Vue and Vue also AngularJS and Angular also the era of jQuery lodash and moment js This is also not about frontend or frameworks We had python and python and JS before and after ECMAScript This is just the top of my mind and there are many more that I myself have no idea or experience with Examples are welcomed in the comments How much do you need to know about what was For a beginner my opinion is that you don t need to know anything but whatever is freshest out there When I learned React I knew class components existed and that was it Functional components were enough for everything I needed and even today as far as I m aware you need class components for one case only Error Boundary and even then there are packages that neatly abstract that into functional More than that if you re starting now you would have multiple sources using the latest versions and a lot of people to learn with along than if you choose to start in an outdated or niche language framework Imagine trying to learn COBOL as a first language today In the case of React the problem is of course legacy In React you can have the legacy part side by side with the new code In other languages frameworks you would have only the legacy or it somehow segregated in a small part or microservice The overhead cost of the legacy stackIn the case of React depending on your source and your legacy code you would expose newbies to class components Redux and probably moment and lodash A totally valid stack back then probably sprinkled with functional components hooks and a different version of ECMAScript functions being used depending on when it was written All of that before actually having to use the “current stack and learn all the business rules and project structure Meanwhile today you can start with functional components hooks including Context API some basic JS the business rules and project structure and you tackle anything else you might need as you go The basics are important just not now One would probably start to actually code a lot sooner and without a lot of unneeded preconceptions than the other one that with luck would only mix and stumble on a lot of things that they learned…that is if they didn t give up before that There s no need to “appreciate all that came before otherwise you would need to start in Assembly code all the Data Structures and Algorithms in C and do all the Design Patterns in Java to finally do a “Hello World in JS Types Data Structures Algorithms Design Patterns and the older version of the framework language and packages you use today…that comes later and probably with a problem attached to it How much to start out Ignore all but the essentials and make it work Ask for reviews and make it right Learn some more and make it better Yes I m parodying Kent Beck s phrase Make it work Make it right Make it fast In other words Learn the least necessary to make it work Don t try to understand all of it just trust that it works and be happy for now Have mentors and ask for code reviews In other words code and show people your errors Learn from the feedback and code some more Learn yet more go as deep as you need or want and code more and better Your turn If you re beginning code and show us the code Else comment on how you ve started coding or why I m wrong Cover Photo by Braden Collum on Unsplash	2022-08-21 18:04:29
