• How Can I Configure Storybook to Use React-App-Rewired ?

  8 août 2022, par joseph

  I'm working on a project that implements react-app-rewired to send headers to the server in order to bypass ReferenceError: SharedArrayBuffer is not defined (I'm getting this error from using the @ffmpeg/ffmpeg library).

  


  // config-overrides.js
const {
  override,
  // disableEsLint,
  // addBabelPlugins,
  // overrideDevServer
} = require('customize-cra')

module.exports = {
  devServer(configFunction) {
    // eslint-disable-next-line func-names
    return function (proxy, allowedHost) {
      const config = configFunction(proxy, allowedHost)

      // Set loose allow origin header to prevent CORS issues
      config.headers = {
        'Access-Control-Allow-Origin': '*',
        'Cross-Origin-Opener-Policy': 'same-origin',
        'Cross-Origin-Embedder-Policy': 'require-corp',
        'Cross-Origin-Resource-Policy': 'cross-origin'
      }

      return config
    }
  }
}


  


  // package.json
"scripts": {
  "start": "react-app-rewired start",
  "build": "react-app-rewired build",
  "test": "react-app-rewired test  --transformIgnorePatterns \"node_modules/(?!siriwave)/\"",
  "eject": "react-scripts eject",
  "storybook": "start-storybook -p 6006 -s public",
  "build-storybook": "build-storybook -s public"
}


  


  Though this works when I run npm start, meaning the headers get sent to the server, it doesn't work when I run npm run storybook, and I still get the SharedArrayBuffer is not defined error. I'm assuming it's because npm run storybook still uses react-scripts as opposed to react-app-rewired under the hood, but I'm not sure where I can change the configurations for this. Any ideas ?

  


• checkasm : Serialize read_time() calls on x86

  8 octobre 2014, par Henrik Gramner

  checkasm : Serialize read_time() calls on x86
  Improves the accuracy of benchmarks, especially in short functions.
  To quote the Intel 64 and IA-32 Architectures Software Developer’s Manual :
  
  "The RDTSC instruction is not a serializing instruction. It does not necessarily
  
  wait until all previous instructions have been executed before reading the counter.
  
  Similarly, subsequent instructions may begin execution before the read operation
  
  is performed. If software requires RDTSC to be executed only after all previous
  
  instructions have completed locally, it can either use RDTSCP (if the processor
  
  supports that instruction) or execute the sequence LFENCE ;RDTSC."
  RDTSCP would accomplish the same task, but it’s only available since Nehalem.
  This change makes SSE2 a requirement to run checkasm.

• Cut audio / Video using ffmpeg on the server [on hold]

  8 décembre 2016, par Mohammed Hussein

  I am rebuilding a project that I built with meteor js from scratch using asp.net mvc and c#

  the project is basically used to cut audio and video given the start time and the end time using ffmpeg on the server,

  but I am facing a problem in both projects,

  if during the process of cutting the audio / video file i lost my internet connection the operation doesn’t complete. what i want is that the operation should complete and write the changes to the database and create the new file on the server despite the fact that i am no longer connected .

  is that possible to do or not ?
