海外TECH	DEV Community	Denoising time series data by using wavelet transformation	https://dev.to/atimin/denoising-timeseries-data-by-using-waveletbuffer-121a	Denoising time series data by using wavelet transformationA popular approach for conditional monitoring of mechanical machines is to embed vibration sensors into a machine and start listening to it The data from the sensors must be stored somewhere So the more efficient we compress them the longer history we can keep When we deal with sensors we always have noise from them and when a machine is stopped we have only noise which wastes our storage space WaveletBuffer was developed to solve this problem by using the wavelet transformation and efficient compression of denoised data However a user must know many settings to use it efficiently In this tutorial you will learn how to find denoising parameters to get rid of white noise in your data BasicsFor an educational purpose I brought two samples from a vibration sensor which is maintained on a real machine You can find them in the directory docs tutorials buffer signal bin contains a second of the signal when the machine is working buffer no signal bin has only noise because the machine is stopped Both files are serialized buffer without any denoising so they have equal sizes but different amount of the information We need to separate white noise and information so we need the sample with the working machine Let s deserialize it from wavelet buffer import WaveletBuffer denoiseimport numpy as npimport matplotlib pyplot as pltblob b with open buffer signal bin rb as f blob f read print f Initial size len blob kB buffer WaveletBuffer parse blob print buffer Output Initial size kBWaveletBuffer lt signal number signal shape decomposition steps wavelet type WaveletType DB gt You can see that the signal has about points and the size of the file is about kB Let s have a look at the signal inside signal buffer compose plt plot signal plt show Looks noisy right When we ve restored the original signal we can use WaveletBuffer to denoise it We use some random threshold for the demonstration Later we learn how to find the optimal parameter When we pass denoise Threshold a b in WaveletBuffer decompose method it set to all values in hi frequency subbands which less than a x b where x is a decomposition step of the current subband buffer decompose signal denoise Threshold a b this a x where x is a decomposition stepdenoised buffer compose plt plot denoised plt show Information Loosing DetectionThe denoised signal looks the same but we actually don t know if we removed only the noise or we removed some part of the signal To figure out it we can take the difference between the denoised and original signals and check if it has some information or only noise It has some information and means we deleted with denoising err denoised signalplt plot err plt show To check if the difference err has something more than only noise we can find autocorrelation of error and test if all the values lie within sqrt n sqrt n where n is the size of sample For more detail see here def autocorr x result np correlate x x mode full return result int len result def test corr np ndarray thr np sqrt len corr tests np where np abs corr lt thr return tests sum corr autocorr err print test corr OutputFalse Optimal Denoise ParametersYou can see that for denoise Threshold we removed something important from our signal However the desnoised signal looked the same To find the optimal threshold we can start from and increasing the threshold with a little step until we fail the test threshold step for x in range threshold step x buffer decompose signal denoise Threshold threshold err buffer compose signal corr autocorr err if not test corr threshold threshold step print f Optimal threshold threshold breakOutput Optimal threshold You see that the threshold way less than our initial assumption Let s check the size of serialized signal buffer decompose signal denoise Threshold threshold print f Compression size len buffer serialize compression level kB signal buffer compose plt plot signal plt show Output Compression size kBLooks like it got times smaller after the demonising However the most interesting thing is compression of the sample when the machine was stopped blob b with open buffer no signal bin rb as f blob f read buffer WaveletBuffer parse blob buffer decompose buffer compose denoise Threshold threshold signal buffer compose print f Compression onlynoise size len buffer serialize compression level kB plt plot signal plt show Output Compression onlynoise size kBThe compressed size is times smaller now because we don t have valuable information in the sample ConclusionWaveletBuffer provides a pipeline wavelet transormation gt denoising gt compression which is useful for efficient compression of height frequency time series data This approach has an additional advantage for data sources which don t provide valuable information all the time but are requested continuously References White Noise Model Time Series Analysis Regression and ForecastingWaveletBuffer A universal C compression library based on

海外TECH	DEV Community	CUDOS Developers’ value to the Decentralisation of Cloud networks Goals	https://dev.to/mrbitee/cudos-developers-value-to-the-decentralisation-of-cloud-networks-goals-55ic	CUDOS Developers value to the Decentralisation of Cloud networks GoalsCudos is a decentralized cloud network that enables users to leverage their unused computing power storage and bandwidth resources to earn Cudos tokens Cudos aims to expand its developer community by providing opportunities for developers to contribute towards the development of its eco system We are looking for experienced developers who would like to join our Rangers program and help us build the next generation decentralized applications Virtual machineVirtual machines are the backbone of cloud computing These software constructs allow us to launch servers databases and even entire operating systems on demand They give us the possibility to migrate quickly from one location to another or even use different hardware configurations IBM introduced virtual machines in the late s as an operating system feature for their mainframes to run multiple applications on one machine without having each application know about the other ones running on it like a modern day container In this early form these virtual machines were not very flexible but they did help solve some problems that could not be solved with previous technologies like dual booting or using an emulator for example In Roland Haitz invented a technique called “para virtualization which allowed him to add some additional instructions in his guest OS so that it could do things that were usually done by hypervisor code aka guest OS This enabled him to run multiple OS instances with different instruction sets e g x vs PowerPC inside one physical host machine ーi e no need for emulators anymore The downside is that this new design required significant changes throughout entire guest OS stack including drivers etc which means the ots of work upfront before being able to reap benefits later down road not something everyone can afford spendingto spendlottime on right now Our developers are working toto spendDOS users have an amazing experience in gaming eshopping etc using virtual machines Our Developers create shopping system friendly Blockchain networkIf you are a developer and have been following Cudos and the blockchain space you know how important it is to have an ecosystem built around your project This means you need developers building your platform s tools apps and dApps The more builders build on your network the apps off it will be in the long run The same goes for all projects in this space if you want a strong community using your token or dApp then there need to be incentives for them to do so aka rewards In order for that reward system to work effectively though to be enough people using said Dapps o therein them aka usage Decentralized pipelinesIf you re familiar with the concept of a pipeline you know that it s a set of tools and services that are used to build test and deploy applications A DevOps toolchain is the backbone of any pipeline It s a series of stages that move code from development to production Most organizations have an established process for creating their pipelines ーbut when we talk about Cudo s developer driven cloud networks we re talking about decentralized pipelines Blockchain oracleThe blockchain is a decentralized ledger That means that it s distributed across many computers and there s no single authority or company that controls its contents In order to verify the truthfulness of data recorded on this ledger one needs an independent source of information ーwhat we call an oracle An oracle acts as a trusted source of information that can be used to verify the truthfulness of data recorded on the blockchain Decentralized storageDecentralized storage is a key component of any decentralized cloud network It s important to understand how Cudos developers can help create a decentralized storage solution that meets the needs of your business Cudos developers have the technical skills needed to create decentralized file systems databases and other forms of decentralized storage solutions for your project or organization These solutions are designed with security and scalability in mind so you can rest assured that your data will be safe from attacks from hackers or other malicious actors who want access to it without your permissionLearn how to contribute to the Cudos network and become a Cudos Ranger You can become a Cudos Ranger and contribute to the network by developing applications for it A Cudos Ranger is an individual who contributes to the Cudos network They do this by creating software that uses interacts with or otherwise supports the Cudos protocol and network These individuals are rewarded for their contributions by being provided with some amount of tokens from a pool owned by the token holders This is called contributing towards becoming a “Cudos Ranger as it implies that they will help guide others through uncharted territory while exploring all that is possible within this new frontier Recent UpdatesWhen it comes to the CUDOS site they made some improvements too The UX for the re delegation process was improved A problem with accessing a direct link to an improvement proposal was resolved On the Validators page there was a caching problem that was fixed When assigning a task to a validator we fixed the “Max button They completed the “My Delegations tab s implementation on the Staking page ConclusionIf you are interested in joining us as a Cudos Ranger then please contact us at any time We would love to have you please contact us anytimeJoin the communityTwitter Mainnet	2022-09-12

海外TECH	DEV Community	Building an interactive screen-sharing app with Puppeteer and React 🤯	https://dev.to/novu/building-an-interactive-screen-sharing-app-with-puppeteer-and-react-12h7	Building an interactive screen sharing app with Puppeteer and React What is this article about You want to give a user the ability to browse a webpage through your system and feel like it s a real browser Why did I create this article For a long time I tried to create a way to do onboarding for members to go through some web page and fill in their details I searched for many open source libraries that can do it and found nothing So I have decided to implement it myself How are we going to do it For this article I will use Puppeteer and ReactJS Puppeteer is a Node js library that automates several browser actions such as form submission crawling single page applications UI testing and in particular generating screenshot and PDF versions of web pages We will open a webpage with Puppeteer send to the client React a screenshot of every frame and reflect actions to Puppeteer by clicking on the image To begin with let s set up the project environment Novu the first open source notification infrastructureJust a quick background about us Novu is the first open source notification infrastructure We basically help to manage all the product notifications It can be In App the bell icon like you have in the Dev Community Websockets Emails SMSs and so on I would be super happy if you could give us a star It will help me to make more articles every week How to create a real time connection with Socket io amp React jsHere we ll set up the project environment for the screen sharing app You ll also learn how to add Socket io to a React and Node js application and connect both development servers for real time communication via Socket io Create the project folder containing two sub folders named client and server mkdir screen sharing appcd screen sharing appmkdir client serverNavigate into the client folder via your terminal and create a new React js project cd clientnpx create react app Install Socket io client API and React Router  React Router is a JavaScript library that enables us to navigate between pages in a React application npm install socket io client react router domDelete the redundant files such as the logo and the test files from the React app and update the App js file to display Hello World as below function App return lt div gt lt p gt Hello World lt p gt lt div gt export default App Navigate into the server folder and create a package json file cd server amp npm init yInstall Express js CORS Nodemon and Socket io Server API Express js is a fast minimalist framework that provides several features for building web applications in Node js  CORS is a Node js package that allows communication between different domains Nodemon is a Node js tool that automatically restarts the server after detecting file changes and Socket io allows us to configure a real time connection on the server npm install express cors nodemon socket ioCreate an index js file the entry point to the web server touch index jsSet up a simple Node js server using Express js The code snippet below returns a JSON object when you visit the http localhost api in your browser index jsconst express require express const app express const PORT app use express urlencoded extended true app use express json app get api req res gt res json message Hello world app listen PORT gt console log Server listening on PORT Import the HTTP and the CORS library to allow data

project to create a real time connection Before the app get block copy the code below Next add Socket io to the project to create a real time connection Before the app get block copy the code below New imports const socketIO require socket io http cors origin http localhost Add this before the app get blocksocketIO on connection socket gt console log socket id user just connected socket on disconnect gt console log A user disconnected From the code snippet above the socket io connection function establishes a connection with the React app then creates a unique ID for each socket and logs the ID to the console whenever a user visits the web page When you refresh or close the web page the socket fires the disconnect event showing that a user has disconnected from the socket Configure Nodemon by adding the start command to the list of scripts in the package json file The code snippet below starts the server using Nodemon In server package json scripts test echo Error no test specified amp amp exit start nodemon index js You can now run the server with Nodemon by using the command below npm start Building the user interfaceHere we ll create a simple user interface to demonstrate the interactive screen sharing feature Navigate into client src and create a components folder containing Home js and a sub component named Modal js cd client srcmkdir componentstouch Home
