海外TECH	DEV Community	"Take Me Out to the Ball Game" Algorithmically Remastered in Python	https://dev.to/dolbyio/take-me-out-to-the-ball-game-algorithmically-remastered-in-python-2o96	quot Take Me Out to the Ball Game quot Algorithmically Remastered in PythonThe  Jack Norworth and Albert Von Tilzer song Take Me Out to the Ball Game has been a classic staple across ballparks becoming synonymous with America s favorite pastime At over years old the original version of Take Me Out to the Ball Game was recorded on a two minute Edison Wax Cylinder by singer and performer Edward Meeker quickly becoming a beloved classic  With the baseball season getting underway this April th we thought it about time to dust off the gloves pick up our bats  step up to our Python environments and get to work algorithmically remastering the classic anthem with the Dolby io Music Mastering API Typically performed by audio engineers Mastering is a labor intensive post production process usually applied as the last step in creating a song and is the final polish that takes a track from good to great Because Take Me Out to the Ball Game was recorded and produced in the mastering and post production technology was very limited and hence it could be interesting to explore the impact of applying a music mastering algorithm on the original recording and the effect that has on the palatability of the track Picking a Version Before we can get started remastering Take Me Out to the Ball Game we first need to pick a version of the song Whilst we often hear the catchy tune played during the middle of the seventh inning  that version isn t the original and is subject to copyright protection For this project we will be using the version found here as it is now available in the public domain and free to use Unfortunately the highest quality version of the song is stored as an MP Whilst this works with the API Free Lossless Audio Codec FLAC or other lossless file types are preferred as they produce the best results during the mastering post production process    The Music Mastering API With our song in hand it s time to introduce the tool that will be doing the majority of the heavy lifting  The Dolby io Music Mastering API is a music enhancement tool that allows users to programmatically master files via a number of sound profiles specific to certain genres and styles The API isn t free however  the company offers trial credits if you sign up and additional trial credits if you add your credit card to the platform For this project the trial tier will be sufficient which is available if you sign up here Once you have created an account and logged in navigate over to the applications tab  select my first app and locate your Media APIs API Key An example screenshot of the Dolby io dashboard It s important to note that all Dobly io media APIs adhere to the  REST framework text A REST API also known by computer scientist Roy Fielding  meaning they are language agnostic For the purposes of this project I will be using the tool in Python however it works in any other language Adding it to the Dolby io ServerTo utilize the Music Mastering API we first need to store the MP file on the cloud This can be done with either a cloud service provider such as AWS or you can use the Dolby io Media Storage platform For simplicity we will use the Dolby io platform which can be accessed via a REST API call To get started we need to import the Python Requests package and specify a path to the MP file on our local machine import requests Requests is useful for making HTTP requests and interacting with REST APIsfile path Take Me Out to the Ball Game mp Next we need to specify the URL we want the Requests package to interact with specifically the Dolby io Media Input address In addition to the input URL we also need to format a header that will authenticate our request to the Dolby io server with our API key  url headers x api key YOUR DOLBY IO MEDIA API KEY Content Type application json Accept application json Finally we need to format a body that specifies the name we want to give our file once it is added to the server  body url dlb input example mp With the URL Head and Body all formatted correctly we can use the Requests package to create a pre signed URL to which we can upload our MP file to response requests post url json body headers headers response raise for status presigned url response json url print Uploading to format file path presigned url with open file path rb as input file requests put presigned url data input file Starting a Mastering JobOnce the audio file has been moved to the cloud we can begin calling a mastering job  The Music Mastering API includes a number of predefined profiles which match up to a selection of audio genres such as Hip Hop or Rock For the best results a Rock song should be mastered with the Rock profile however the process of picking a profile can require a bit of experimentation Because matching creative intent with different sound profiles can take a few trials the API offers a preview version  where you can master a seconds segment of a song with different profiles We format the body of this request to include this information as well as when we want the segment to begin body inputs source dlb input example mp segment start duration seconds is the start of the iconic chorus outputs destination dlb example master preview l mp master dynamic eq preset l Lets master with the Vocal profile destination dlb example master preview m mp master dynamic eq preset m Lets master with the Folk profile destination dlb example master preview n mp master dynamic eq preset n Lets master with the Classical profile The Header stays the same as the one we used to upload the file to the Dolby io Server and the URL changes to match the Music Mastering endpoint url headers x api key YOUR DOLBY IO MEDIA API KEY Content Type application json Accept application json We can use the Requests package to deliver our profile selections and start the mastering job  response requests post url json body headers headers response raise for status print response json job id response json job id This process can take a minute to complete To check the status of the job we can format another request to the same URL with the Job ID included in the body to check the progress of the master  url

status print response json The response from the request outputs the progress of the job between and Downloading the Mastered FileWith our file mastered it s time to download the three master previews so we can hear the difference The workflow for downloading files mirrors that of how the rest of the Dolby io APIs work Much like uploading a file or starting a job we format a header with our API key and a body that points to the mastering output on the Dolby io server import shutil File operations package useful for downloading files from a server url headers x api key api key Content Type

file shutil copyfileobj response raw output file Summary of mastering job workflow from locating the file to downloading results With the mastered files downloaded locally we can listen to both and hear the difference between the original and one of our Masters  The original version of Take Me Out to the Ball Game sung by Edward Meeker in Mastered version of Take Me Out to the Ball Game with the Dolby io Classical music profile Profile n focusing on wide dynamics and warm full tones for orchestral instruments We can also hear the subtle differences between the Masters Mastered version of Take Me Out to the Ball Game with the Dolby io Vocal music profile Profile l focusing on the mid frequencies to highlight vocals Mastered version of Take Me Out to the Ball Game with the Dolby io Folk music profile Profile m focusing on light touch with ample mid frequency clarity to let acoustic instruments shine in the mix Mastered version of Take Me Out to the Ball Game with the Dolby io Classical music profile Profile n focusing on wide dynamics and warm full tones for orchestral instruments For the purposes of this demo we only mastered with the last three profiles however there are  different music mastering profiles to pick from From my testing I like the Classical profile Profile n the best but everyone is different try it out yourself   A More Modern ExampleWhilst the classic still doesn t sound modern remastering the track does make it a little more clear and hence more enjoyable to listen to  Typically the Dolby io Music Mastering API is built for contemporary samples recorded on more modern equipment in lossless formats such as FLAC and is not designed to be an audio restoration tool For the purposes of this investigation we wanted to see the impact post production mastering would have on the track rather than attempting to outright fix the original  Currently the Dolby io team has a demo hosted here that lets you listen to before and after examples of licensed contemporary tracks which better exemplifies the use case of the API Because Dolby io owns the licenses to those songs they are allowed to host the content whereas for this project I wanted to pick a track in the public domain so anyone with an interest can test it out for themselves without fear of infringing on copyright law The Dolby io Music Mastering demo  available here If the Music Mastering API is something you are interested in further exploring check out the dolby io documentation around the API or the live demo mentioned above otherwise let s get excited for an awesome Baseball season ahead and root root root for the home team	2022-04-09 19:54:55

海外TECH	DEV Community	Bad Habits of Mid-Level React Developers	https://dev.to/srmagura/bad-habits-of-mid-level-react-developers-b41	Bad Habits of Mid Level React DevelopersIf you re a mid level React developer looking to become an advanced React developer this post is for you I ve been reviewing React code written by junior and mid level developers on a daily basis for a couple of years now and this post covers the most common mistakes I see I ll be assuming you already know the basics of React and therefore won t be covering pitfalls like don t mutate props or state Bad HabitsEach heading in this section is a bad habit that you should avoid I ll be using the classical example of a to do list application to illustrate some of my points Duplicating stateThere should be a single source of truth for each piece of state If the same piece of information is stored in state twice the two pieces of state can get out of sync You can try writing code that synchronizes the two pieces of state but this is an error prone band aid rather than a solution Here s an example of duplicate state in the context of our to do list app We need to track the items on the to do list as well as which ones have been checked off You could store two arrays in state with one array containing all of the to dos and the other containing only the completed ones const todos setTodos useState lt Todo gt const completedTodos setCompletedTodos useState lt Todo gt But this code is buggy at worst and smelly at best Completed to dos are stored in the state twice so if the user edits the text content of a to do and you only call setTodos completedTodos now contains the old text which is incorrect There are a few ways to deduplicate your state In this contrived example you can simply add a completed boolean to the Todo type so that the completedTodos array is no longer necessary Underutilizing reducersReact has two built in ways to store state useState and useReducer There are also countless libraries for managing global state with Redux being the most popular Since Redux handles all state updates through reducers I ll be using the term reducer to refer to both useReducer reducers and Redux reducers useState is perfectly fine when state updates are simple For example you can useState to track whether a checkbox is checked or to track the value of a text input That being said when state updates become even slightly complex you should be using a reducer In particular you should be using a reducer ANY TIME you are storing an array in state In the context of our to do list app you should definitely manage the array of to dos using a reducer whether that s via useReducer or Redux Reducers are beneficial because They provide a centralized place to define state transition logic They are extremely easy to unit test They move complex logic out of your components resulting in simpler components They prevent state updates from being overwritten if two changes occur simultaneously Passing a function to setState is another way to prevent this They enable performance optimizations since dispatch has a stable identity They let you write mutation style code with Immer You can use Immer with useState but I don t think many people actually do this Not writing unit tests for the low hanging fruitDevelopers are busy people and writing automated tests can be time consuming When deciding if you should write a test ask yourself Will this test be impactful enough to justify the time I spent writing it When the answer is yes write the test I find that mid level React developers typically do not write tests even when the test would take minutes to write and have a medium or high impact These situations are what I call the low hanging fruit of testing Test the low hanging fruit In practice this means writing unit tests for all standalone functions which contain non trivial logic By standalone I mean pure functions which are defined outside of a React component Reducers are the perfect example of this Any complex reducers in your codebase should have nearly test coverage I highly recommend developing complex reducers with Test Driven Development This means you ll write at least one test for each action handled by the reducer and alternate between writing a test and writing the reducer logic that makes the test pass Underutilizing React memo useMemo and useCallbackUser interfaces powered by React can become laggy in many cases especially when you pair frequent state updates with components that are expensive to render React Select and FontAwesome I m looking at you The React DevTools are great for identifying render performance problems either with the Highlight updates when components render checkbox or the profiler tab Your most powerful weapon in the fight against poor render performance is React memo which only rerenders the component if its props changed The challenge here is ensuring that the props don t change on every render in which case React memo will do nothing You will need to employ the useMemo and useCallback hooks to prevent this I like to proactively use React memo useMemo and useCallback to prevent performance problems before they occur but a reactive approach ーi e waiting to make optimizations until a performance issue is identified ーcan work too Writing useEffects that run too often or not often enoughMy only complaint with React Hooks is that useEffect is easy to misuse To become an advanced React developer you need to fully understand the behavior of useEffect and dependency arrays If you aren t using the React Hooks ESLint plugin you can easily miss a dependency of your effect resulting in an effect that does not run as often as it should This one is easy to fix ーjust use the ESLint plugin and fix the warnings Once you do have every dependency listed in the dependency array you may find that your effect runs too often For example the effect may run on every render and cause an infinite update loop There s no one size fits all solution to this problem so you ll need to analyze your specific situation to figure out what s wrong I will say that if your effect depends on a function storing that function in a ref is a useful pattern Like this const funcRef useRef func useEffect gt funcRef current func useEffect gt do some stuff and then call funcRef current Not considering usabilityAs a frontend developer you should strive to be more than just a programmer The best frontend developers are also experts on usability and web design even if this isn t reflected in their job titles Usability simply refers to how easy it is to use an application For example how easy is it to add a new to do to the list If you have the opportunity to perform usability testing with real users that is awesome Most of us don t have that luxury so we have to design interfaces based on our intuition about what is user friendly A lot of this comes down to common sense and observing what works or doesn t work in the applications you use everyday Here s a few simple usability best practices that you can implement today Make sure clickable elements appear clickable Moving your cursor over a clickable element should change the element s color slightly and cause the cursor to become a pointing hand i e cursor pointer in CSS Hover over a Bootstrap button to see these best practices in action Don t hide important UI elements Imagine a to do list app when there X button that deletes a to do is invisible until you hover over that specific to do Some designers like how clean this is but it requires the user to hunt around to figure out how to perform a basic action Use color to convey meaning When displaying a form use a bold color to draw attention to the submit button If there s a button that permanently deletes something it better be red Check out Bootstrap s buttons and alerts to get a sense of this Not working towards mastery of CSS amp web designIf you want to create beautiful UIs efficiently you must master CSS and web design I don t expect mid level developers to immediately be able to create clean and user friendly interfaces while still keeping their efficiency high It takes time to learn the intricacies of CSS and build an intuition for what looks good But you need to be working towards this and getting better over time It s hard to give specific tips on improving your styling skills but here s one master flexbox While flexbox can be intimidating at first it is a versatile and powerful tool that you can use to create virtually all of the layouts you ll need in everyday development That covers the bad habits See if you are guilty of any of these and work on improving Now I ll zoom out and discuss some big picture best practices that can improve your React codebases General Best Practices Use TypeScript exclusivelyNormal JavaScript is an okay language but the lack type checking makes it a poor choice for anything but small hobby projects Writing all of your code in TypeScript will massively increase the stability and maintainability of your application If TypeScript feels too complex to you keep working at Once you gain fluency you ll be able to write TypeScript just as fast as you can write JavaScript now Use a data fetching libraryAs I said in the Bad Habits section of this post writing useEffects correctly is hard This is especially true when you are using useEffect directly to load data from your backend s API You will save yourself countless headaches by using a library which abstracts away the details of data fetching My personal preference is React Query though RTK Query SWR and Apollo are also great options Only use server rendering if you really need itServer side rendering SSR is one of the coolest features of React It also adds a massive amount of complexity to your application While frameworks like Next js make SSR much easier there is still unavoidable complexity that must be dealt with If you need SSR for SEO or fast load times on mobile devices by all means use it But if you re writing a business application that does not have these requirements please just use client side rendering You ll thank me later Colocate styles with componentsAn application s CSS can quickly become a sprawling mess that no one understands Sass and other CSS preprocessors add a few nice to haves but still largely suffer from the same problems as vanilla CSS I believe styles should be scoped to individual React components with the CSS colocated with the React code I highly recommend reading Kent C Dodds excellent blog post on the benefits of colocation Scoping CSS to individual components leads to component reuse as the primary method of sharing styles and prevents issues where styles are accidentally applied to the wrong elements You can implement component scoped colocated styles with the help of Emotion styled components or CSS Modules among other similar libraries My personal preference is Emotion with the css prop	2022-04-09 19:03:09
