海外TECH	DEV Community	Making a page builder with CloudCannon	https://dev.to/cloudcannon/making-a-page-builder-with-cloudcannon-3kmm	Making a page builder with CloudCannonBy Jordan TrbuhovicPage builders give editors an intuitive and easy way to manage and build websites All editing can be done within CloudCannon s Visual Editor in real time Live editing on CloudCannon is enabled with the use of Bookshop Bookshop is a component development workflow for static websites which currently supports Jekyll and Eleventy and will support a wider variety of static site generators in the near future Bookshop helps you to create a component based file structure which works out of the box with CloudCannon s array structures See our documentation on array structures for more information This setup allows CloudCannon to immediately re render any changes to page components and edits within the Visual Editor Getting StartedDownload or fork our example repositories Jekyll ty from GitHub If you ve downloaded the example website you will need to unzip it With your terminal change directory into the website e g cd desktop page builder example jekyll To run the website locally run the following commands Install ty npm iInstall Jekyll npm i amp amp bundle installRun the stack npm startYour website can now be opened in a web browser by visiting the URL listed in your terminal Once the website is built and uploaded to CloudCannon you will be able to use the live editing features Directory structureAfter unzipping or cloning the example website you will see the following directories cloudcannon This is a hidden directory so it will only be visible if you open the website with your text editor component librarybookshopcomponentssharedsiteThese are all necessary for Bookshop and enable live editing with CloudCannon cloudcannon contains a pre build script that tells CloudCannon to install any dependencies and run the Bookshop script Without this live editing on CloudCannon won t be possible component library has three directories which contain the website components shared styles Bookshop config etc The components directory is where all of your components should be built Each component has its own folder which holds everything relating to it component lt framework gt The component templatecomponent bookshop toml The configuration front matter settings for the component on CloudCannoncomponent scss The styles for the componentThis gives you an easy to manage component library with self contained components Bookshop automatically compiles the styles on build and turns all components into array structures for CloudCannon You don t need to worry about adding including or importing these files anywhere site contains all of the Jekyll or Eleventy files for your website You can build your website as you would with any other site within this directory Your site is separated from Bookshop for better organization Creating new componentsPage components give editors a collection of different content types layouts that can be used to build pages Bookshop only enables live editing for components so if you have other hard coded content structures these will not live update when modified via front matter When creating new components they should be added to a folder with the name of the component inside the component library gt components folder This component folder must contain the three files mentioned in the Directory structure section component template file component TOML file component styles An example of a new component would look like this component library components my new component my new component bookshop toml my new component jekyll html my new component scssTo help with this process you can run the Bookshop gen command which will create a skeleton for any new component npx bookshop gen name my new component Using ComponentsTo give editors access to components you need to add the content blocks key to the front matter of any page you want components to be accessible on Example index html title Welcome to our websitecontent blocks Once the website has been built on CloudCannon content blocks will be shown as a button within the Visual Editor that lets you choose which components to add to the page content blocks links to the structure listed in the TOML file of each component which auto populates the component picker Components that get added to the content blocks array are rendered onto pages with the following code which is located in the default page layout lt body gt lt main gt lt The page include loops through all content blocks and renders them Using a bookshop tag here means that live previewing will catch new components gt bookshop include page content blocks content blocks lt main gt lt This tag registers live previewing on CloudCannon gt bookshop live cloudcannon bookshop live js lt body gt page lt framework gt referenced in the codeblock above for block in content blocks lt div class cms editor link data cms editor link cloudcannon content blocks forloop index gt lt span class cms editor button gt lt span gt bookshop block bookshop name bind block lt div gt endfor You can modify the default page layout in the example website if you want to change the way components are rendered Uploading syncing to CloudCannonTo get your new Bookshop site on CloudCannon you need to log in to your account and create a new site You can choose to sync a repository upload a folder or upload the zip downloaded from this post If you re uploading a folder make sure the cloudcannon folder is checked when selecting files to upload If this is unchecked you will get build errors and won t be able to use the live editing features SummaryAfter learning the basics of how Bookshop can be integrated into a website you should now have live editing for components in CloudCannon s Visual Editor The structure in the example website is a good base for starting or converting any static website to a Bookshop component based website To dive deeper into Bookshop and how it works check out the Bookshop Guides You can also use Bookshop in a theme to save duplicating components and styles across websites that use the same themes or layouts We do this for our Bookshop templates which are free for anyone to use and modify For further reading on themes see our other posts on creating themes with GitHub or with Gemfury	2021-10-06 16:52:02
海外TECH	DEV Community	Create a Simple Stopwatch using JavaScript	https://dev.to/shantanu_jana/create-a-simple-stopwatch-using-javascript-3eoo	Create a Simple Stopwatch using JavaScriptIn this article you will learn how to make a simple stop watch using JavaScript Stopwatch is a simple JavaScript project that is important enough for beginners This type of project is used to count some time The most important point of this design is that here you can count milliseconds i e hours minutes seconds and milliseconds Watch its live demo to learn how it works First I designed the webpage and then created a box In that box I have made a display where the counting times can be seen It has three buttons which are used to start the countdown stop it and start the countdown again If you know basic JavaScript you can easily understand For beginners I have given full details explanation Step Basic structure of stopwatchWe have created the basic structure of this stop watch using the following HTML and CSS codes First I designed the web page with the help of CSS code Here I used the background color blue of the page I have used box width and minimum width px Border radius px is used to round the four corners of the box lt div class container gt lt div gt before after padding margin box sizing border box body background aff container background color ffffff width min width px position absolute transform translate top left padding px padding bottom px border radius px Step Create a display to see the timeI created a display in this box using these HTML and CSS codes This display will help to see who is counting time Here you can see the count of hours minutes seconds and milliseconds A shadow has been used around this display which has enhanced its beauty Also using font size px here will increase the size of the time a bit lt div class timerDisplay gt lt div gt timerDisplay position relative width background ffffff left padding px font family Roboto mono monospace color bb font size px display flex align items center justify content space around border radius px box shadow px rgba Step Create buttons in the JavaScript stopwatchNow the following HTML and CSS codes have been used to create three buttons in the stopwatch Each button has a width of px and a height of px I have used font size px to increase the size of the text in the button lt div class buttons gt lt button id pauseTimer gt Pause lt button gt lt button id startTimer gt Start lt button gt lt button id resetTimer gt Reset lt button gt lt div gt buttons width margin px auto auto display flex justify content space around buttons button width px height px background color e color ffffff border none font family Poppins sans serif font size px border radius px cursor pointer outline none Using the css below I set the background color of the second and third buttons Above we set the blue color for the background of the button but now using nth last child I set different colors for the second and third buttons buttons button nth last child background color d buttons button nth last child background color b Step Activate the stopwatch using JavaScriptNow is the time to activate this stopwatch using JavaScript Above we have completed the complete design work using HTML and CSS If you know basic JavaScript you can easily understand your own JavaScript explanations I have determined the value of some information using the following three line code First I set the value of hour minute second millisecond to zero This means that these values ​​will be zero when the countdown starts With set a constant of the display id let milliseconds seconds minutes hours let timerRef document querySelector timerDisplay let int null Now I have executed the start button using JavaScript below As a result the countdown will start when you click on that button Under normal circumstances the countdown value will be The countdown will increase every millisecond when you click on it document getElementById startTimer addEventListener click gt if int null clearInterval int int setInterval displayTimer I have implemented the pause button using these codes The countdown will stop when you click on this button document getElementById pauseTimer addEventListener click gt clearInterval int I have implemented the reset button using the following codes As a result when you click on the reset button the time in the display will return to the previous state ie zero When you click on this button the value of hours minutes seconds milliseconds will become zero document getElementById resetTimer addEventListener click gt clearInterval int milliseconds seconds minutes hours timerRef innerHTML Now I have used the if function here to make the stopwatch work I ve tried to give a full explanation of how it works I have used the if function three times and using each function I have given a specific condition First I set the time in milliseconds ➤When the value of milliseconds is equal to we will see zero in the millisecond cell and the number of seconds will increase by one Because we all know milliseconds equals second ➤I have given the condition that when the value of the second is we will see zero in the second cell and one increment in the minute cell ➤The third time I used the if function I executed the time in minutes When the minute time reaches you will see in the minute cell and in the hour cell This way you can run a countdown of many more pieces of information such as days months etc by following the same rules function displayTimer milliseconds if milliseconds milliseconds seconds if seconds seconds minutes if minutes minutes hours Now using the following four lines of JavaScript I have added one zero to the case of one number of times When the value of the countdown time is less than ten we add a zero Here we have given the condition when the value of hour minute second and millisecond is less than then one zero is added to it Then that time will be transmitted in h m s ms You can watch its live demo As you can see below I have used a little extra code in milliseconds This is because milliseconds are made up of four numbers which means there are zeros So in this case I have added the condition twice The first time I used the condition when the time value is less than two zeros will be added A zero will be added when the value of time is less than let h hours lt hours hours let m minutes lt minutes minutes let s seconds lt seconds seconds let ms milliseconds lt milliseconds milliseconds lt milliseconds milliseconds As you can see above we have stored all the time of the countdown in h m s ms Now you have to sort all this information into the display using innerhtml innerhtml helps to organize any information in the HTML page For your convenience I have given below a picture which will help you to know how the code below works timerRef innerHTML h m s ms The above explanation I have tried my best to explain the codes If you have any more questions you can ask me directly on my Instagram foolishdeveloper Final javascript codeBelow we have put together the complete JavaScript code for your convenience let milliseconds seconds minutes hours let timerRef document querySelector timerDisplay let int null document getElementById startTimer addEventListener click gt if int null clearInterval int int setInterval displayTimer document getElementById pauseTimer addEventListener click gt clearInterval int document getElementById resetTimer addEventListener click gt clearInterval int milliseconds seconds minutes hours timerRef innerHTML function displayTimer milliseconds if milliseconds milliseconds seconds if seconds seconds minutes if minutes minutes hours let h hours lt hours hours let m minutes lt minutes minutes let s seconds lt seconds seconds let ms milliseconds lt milliseconds milliseconds lt milliseconds milliseconds timerRef innerHTML h m s ms Hopefully from this article you have learned how to create this simple stopwatch timer using JavaScript You must comment on how you like this design You can visit my blog for more tutorials like this	2021-10-06 16:20:29
海外TECH	DEV Community	Container Runtime in Rust - Part II	https://dev.to/penumbra23/container-runtime-in-rust-part-ii-34em	Container Runtime in Rust Part IIPart I of the series described the filesystem layout and how the runtime jails the container process inside the root filesystem of the container Part II dives a bit deeper into the implementation and shows how the runtime creates the child process and how they communicate until the point where the user defined process kicks in It will also describe how a pseudo terminal is set up and show the importance of Unix sockets By the end of this part we should have a basic runtime that s interoperable with Docker ClonePart briefly explained the clone syscall It s like fork vfork but with more options to control the child process Actually some implementations of fork propagate the call to clone Besides controlling which parts of the execution context get shared from the parent process the clone call offers the possibility for us to create a separate memory block for the child s stack The nix implementation of clone has the following signature pub fn clone cb CloneCb lt gt stack amp mut u flags CloneFlags signal Option lt c int gt gt Result lt Pid gt The signal argument if specified is sent back to the parent when the child process terminates Here is the code snippet depicting the create command and the parent child relation pub fn create create Create let container id create id let root create root let bundle create bundle Load config json specification file let spec match Spec try from Path new amp bundle join config json as path Ok spec gt spec Err err gt error err exit const STACK SIZE usize MB let ref mut stack u STACK SIZE STACK SIZE Take namespaces from config json let spec namespaces spec linux namespaces into iter map ns to flags ns reduce a b a b let clone flags match spec namespaces Some flags gt flags None gt CloneFlags empty let child clone Box new child fun stack clone flags None Parent process One problem that arises from viewing the above is the communication between parent and child In the case of spawning a thread one could say that creating an in memory channel would solve the issue Rust has excellent support for multithreading and thread safe multi producer single consumer queue In our example this is not the case because it s creating or better say cloning a new process with its separate memory space Inter process communication IPC is a set of techniques that allows processes to communicate with each other The two most widely used are shared memorysocketsIn our example we ll use Unix sockets AF UNIX to establish a client server channel between the parent and the child processes The container process is going to bind to that Unix socket and listen for incoming connections from the parent process Both processes will use the socket connection to inform each other when different parts of the execution pass or fail The socket connection also comes in handy when the start command is being invoked to inform the container process to start the user defined program The following diagram describes the protocol better Unix SocketsFor those unfamiliar with Unix domain Sockets this Linux feature will hopefully be mind blowing at least for me it was Unix sockets are an inter process communication mechanism that establishes a two way data exchange channel between processes running on the same machine One can think of them as TCP IP sockets that don t use the network stack to send and receive data but a file on the filesystem In the case of the container runtime Unix sockets offer a bi directional data exchange for the runtime parent and child process That exchange channel is essential for the container runtime What if something breaks down in the child process How can the parent process continue Or how does the child know when the start command gets invoked For these purposes the container runtime implements IPC channels Those are bidirectional channels using Unix domain sockets One process acts as a server and the other processes known as clients connect to the server process To shorten up the story here s a rough idea of how that Rust code might look pub struct IpcChannel fd i sock path String client Option lt i gt impl IpcChannel pub fn new path amp String gt Result lt IpcChannel gt let socket raw fd socket AddressFamily Unix SockType SeqPacket SockFlag SOCK CLOEXEC None map err Error msg unable to create IPC socket to string err type ErrorType Runtime let sockaddr SockAddr new unix Path new path map err Error msg unable to create unix socket to string err type ErrorType Runtime bind socket raw fd amp sockaddr map err Error msg unable to bind IPC socket to string err type ErrorType Runtime listen socket raw fd

socket to string err type ErrorType Runtime Ok IpcChannel fd socket raw fd sock path path clone client None pub fn accept amp mut self gt Result lt gt let child socket fd nix sys socket accept self fd map err Error msg unable to accept incoming socket to string err type ErrorType Runtime self client Some child socket fd Ok pub fn send amp self msg amp str gt Result lt gt let fd match self client Some fd gt fd None gt self fd write fd msg as bytes map err err Error msg format unable to write to unix socket err err type ErrorType Runtime Ok pub fn recv amp self gt Result lt String gt let fd match self client Some fd gt fd None gt self fd let mut buf let num read fd amp mut buf unwrap match std str from utf amp buf num Ok str gt Ok str trim to string Err gt Err Error msg error while converting byte to string to string err type ErrorType Runtime pub fn close amp self gt Result lt gt close self fd map err Error msg error closing socket to string err type ErrorType Runtime std fs remove file amp self sock path map err Error msg error removing socket to string err type ErrorType Runtime Ok The server calls the new method and binds to the  sock file Then it calls accept and waits for incoming connections On the other hand the client just calls connect with the same  sock file and after that the server and client can exchange messages In the end both processes call close and the communication is finished Note that I ve used SOCK SEQPACKET sockets because the messages come in order it s connection based and the message gets flushed all at once opposite to SOCK STREAM TerminalTo have a nice interaction with the container once it starts the runtime should be able to provide a terminal interface if the user requested a terminal When running a Docker command like this one docker run alpine ping  you will see the output of the ping command sending ICMP requests to Google s DNS The output of the ping command is piped through Docker but when we want to stop the command by using Ctrl C nothing happens That s because when pressing the SIGINT key combination the signal is sent to Docker which isn t passing the command to the actual container process On the other side when running docker run it alpine ping and pressing Ctrl C the command terminates immediately as if it runs on the host machine Why is that That s because in the first example the container process doesn t have a terminal instantiated therefore the user nor Docker can t forward the signal to the container via tty Luckily for us the t option sets the terminal true flag inside the config json file After that it s the container runtime s responsibility to create a so called pseudo terminal pty To simplify things a PTY is a master slave pair of communication devices that act like a real terminal Any command sent to the master gets forwarded to the slave end from text input to process signals PTYs are a very important and used feature of the Linux kernel ssh uses it Now it s simple if terminal true the container runtime creates a PTYthe slave descriptor goes to the child processthe master descriptor goes to the calling process in this case Docker But how does the child process send the master descriptor to Docker Sigh…This was a real PITA to find out and the solution was outside the scope of the OCI runtime spec runc developed a solution for which the steps are described here TLDR our friend Unix sockets came to help Docker creates a Unix domain socket and passes it to the container runtime as console socket argument After the container runtime creates the PTY it sends the master end to that same Unix socket with SCM RIGHTS ConclusionFinally we have a ready to test OCI container runtime  This part explained the clone syscall and how it detaches the execution context from the parent process It also has a flexible API so that we can specify the new stack for the process Unix domain sockets play a big role here because they sync the whole parent child communication and handle potential scenes when errors show up on both sides Part II rounds up the Container Runtime in Rust series The whole source code for the experimental container runtime can be found on this Github repo Feel free to ask questions or point interesting things out in the implementation	2021-10-06 16:13:20
海外TECH	DEV Community	Understanding and Using a Web3 Wallet	https://dev.to/coffeecraftcode/understanding-and-using-a-web3-wallet-17mg	Understanding and Using a Web Wallet IntroductionIn this tutorial you will learn what a web wallet digital wallet is why you would use one and how to use the popular wallet MetaMask To understand what a web wallet is it can help to learn a few terms you may not be familiar with BlockchainWhen you have physical currency you store it in a wallet purse or in your bank With digital currency there is no physical money to store Instead the data for a digital currency is stored on a blockchain A blockchain is a running ledger of transactions similar to a bank statement Unlike your bank statement a blockchain ledger can be read by anyone Private and Public KeysIf you store your money in a bank you have an account number This account number can be shared with others so that they can send you money Like an account number a public key is code you can share that allows you to receive digital currency When you use online banking or a debit code at am ATM you have a password or pin to access your money Likewise you use a private key to access your cryptocurrency Like your pin or password a private key should remain private Do not shared with others or they could access your funds Hot and Cold WalletIn this walkthrough we will be using a hot wallet also known as a software wallet A hot wallet stores your private and public keys online It is important to know this because it could mean your information is more vulnerable A cold wallet is generally considered a less vulnerable form of digital wallet A cold wallet is hardware that generates and stores your private key offline What is a Web Wallet A web wallet is hardware or software that allows you to send receive or store cryptocurrency securely without the need for a rd party like your bank Why use a wallet Your web wallet is your key to access your funds The wallet will store your digital currency similar to how you store paper money in a physical wallet If you want to send cryptocurrency or receive it you will also need a wallet By the end of this tutorial you will have your own web wallet set up on your browser of choice Note The digital wallet in this tutorial MetaMask is specific to Ethereum After setting up the wallet you will be able to buy send or receive Ethereum s cryptocurrency ETH and any ETH based token There are other wallets available for different cryptocurrencies PrerequisitesBefore you begin this guide you ll need to have one of the following supported browsers to use the MetaMask extension ChromeFireFoxEdgeBraveSafari is currently unsupported How to use MetaMask Step Downloading the Browser ExtensionIn this step you ll download the MetaMask browser extension for your supported browser In this tutorial the Chrome Browser extension is used as an example Navigate to the Chrome web store and search metamask Click the MetaMask option to redirect to the extension Now click the Add to Chrome button to download the extension You will be asked for permissions If you are comfortable with the permissions requested click Add extension The extension should start to download and take you to a Get Started page Click the Get Started button to continue Step Creating an AccountIn this step you will create an account to use with your MetaMask Wallet If you already have a wallet you can choose to import it If not click the Create a Wallet button You will be asked for more permissions If you are comfortable with the requested permissions click I Agree You will then be prompted to create a password This password is different than the private key that will be generated It is a good idea to use a strong password You will need to read and agree to the Terms of Use and than you can click CreateYou will now be shown a secret backup phrase This phrase will allow you to restore your account and recover your funds Note This phrase should not be shared Anyone with this seed phrase could recover and use your funds There are tips on how you should save this password Take the time to back up your phrase and store it in a secure place Once you have stored your phrase you can click Next You will be prompted to verify the secret backup phrase Once you add the phrase click Confirm to continue You should now see a Congratulations page You can click All Done to continue You can now view your wallet as a small extension on your browser or you can expand the view to see your wallet Step Buying Selling or SwapingNow that your wallet is set up you can buy sell or swap ETH or other ETH based tokens Send and Receive ETHTo send ETH you will need the recipients Account Number You will also need to share your account number to receive ETH from another account For a full walkthrough on how to send ETH please see the article How to send ETH and ERC tokens from your MetaMask wallet Note Your public key is your account number You can share this key to receive payments BuyTo buy ETH you will need to connect your wallet to a debit card or bank This is done through Wyre or Transak Viewing Your Private

海外TECH	DEV Community	How to Create an Interactive Word Tree Chart in JavaScript	https://dev.to/andreykh1985/how-to-create-an-interactive-word-tree-chart-in-javascript-1l3	How to Create an Interactive Word Tree Chart in JavaScriptData visualization is not only useful for communicating insights but also helpful for data exploration There are a whole lot of different chart types that are widely used for identifying patterns in data One of the lesser used chart types is Word Tree It is a very interesting visualization form quite effective in analyzing texts And right now I will teach you how to quickly create nice interactive word tree charts using JavaScript Word trees display how a set of selected words are connected to other words in text data with a branching layout These charts are similar to word clouds where words that occur more frequently are shown bigger But they are different in the sense that word trees also show the connection between the words which adds context and helps find patterns In this tutorial I will create a lovely word tree from the text of the very famous book The Little Prince by French aviator and writer Antoine de Saint Exupéry Check out a demonstration of the final chart below and keep reading to learn how this and any other interactive JS word tree can be built with ease Making a Basic JavaScript Word TreeAn interactive JS word tree chart can look complicated But follow along to learn how to build it in just four really simple steps Create an HTML page Include the required JavaScript files Prepare the data Add some JS code for the chart Create an HTML PageThe initial step is to create an HTML page that will hold the chart In the page add a lt div gt element with an id that will be referenced later lt html gt lt head gt lt title gt JavaScript Word Tree Chart lt title gt lt style type text css gt html body container width height margin padding lt style gt lt head gt lt body gt lt div id container gt lt div gt lt body gt lt html gt To make the word tree occupy the whole page specify the width and height parameters as This can be adjusted as per the requirements of your project Include the Required JavaScript FilesIt is convenient to use a JavaScript charting library to create the word trees The best part of using such libraries is that out of the box charts can be quickly made without advanced technical skills In this tutorial I am working with AnyChart based on its word tree documentation It is free for non commercial use but anyway it is only an example The logic of data visualization remains quite similar for all JS charting libraries So basically you can use this learning to create charts with others that have pre built word trees too I will include the required JS files from the CDN of AnyChart in the lt head gt section of the HTML page For the word tree chart I need to add two scripts the core module and the word tree module lt html gt lt head gt lt title gt JavaScript Word Tree Chart lt title gt lt script src gt lt script gt lt script src gt lt script gt lt style type text css gt html body container width height margin padding lt style gt lt head gt lt body gt lt div id container gt lt div gt lt script gt All the code for the JS word tree chart will come here lt script gt lt body gt lt html gt Prepare the DataI downloaded the text of the famous book The Little Prince by Antoine de Saint Exupéry from an online library and created the data file that you can download here To access the data file I need jQuery and therefore include its script in the code lt script src gt lt script gt Now that all the preliminary steps are done let s get to the main part You are going to love how quickly a functional interactive word tree chart can be made with so few lines of JavaScript code Add Some JS Code for the ChartBefore writing any code the first thing I do is add an enclosing function that executes the code inside it only after the page is ready and then loads the data file using Ajax anychart onDocumentReady function ajax done function text Next I create the chart using the wordtree function of the JS library var chart anychart wordtree text In a word tree an important part is defining the root words which branch out to various sentences in the text Here I define The as the start of the root and drill down to prince as the end of the root so the combined root words become the little prince set the root wordchart word The drill down to the next word in the treechart drillTo prince Finally I just need to set the container and draw the chart set container id for the chartchart container container initiate chart drawingchart draw Voila that s all I do to bring the interactive word tree to life on the web page You can check out this initial version of the JS word tree chart with the code below or on CodePen or on AnyChart Playground lt html gt lt head gt lt title gt JavaScript Word Tree Chart lt title gt lt script src gt lt script gt lt script src gt lt script gt lt script src gt lt script gt lt style type text css gt html body container width height margin padding lt style gt lt head gt lt body gt lt div id container gt lt div gt lt script gt anychart

set container id for the chart chart container container initiate chart drawing chart draw lt script gt lt body gt lt html gt This looks great but there is so much more that can be done to make the word tree look more polished and I will show you how to do that Customizing a JS Word Tree ChartJS charting libraries are great to have a basic visual ready very fast and then a plethora of options to customize the chart Let me show you how to make this word tree more beautiful and personalized Formatting the ConnectorsConfiguring the Font Size and ColorAdding Custom Drill Down and Drill Up
