            How do purely functional languages handle index-based algorithms?
            Asked 2022-Apr-05 at 12:51

            I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.

            For example, consider the following Java code:

            This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]:

            You need to specify the events which you want your bot to receive using gateway intents.

            Instead of

            const client = new Discord.Client();

            Use

            const client = new Discord.Client({ intents: [Enter intents here] })

            For example

            const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })

            The ItemProperties component has multiple root nodes because it renders a list in the root with v-for.

            Based on the class name (infobox-item-properties), I think you want the class to be applied to a container element, so a simple solution is to just add that element (e.g., a div) in your component at the root:

            Group and create three new columns by condition [Low, Hit, High]
            Asked 2022-Feb-10 at 16:22

            I have a large dataset (~5 Mio rows) with results from a Machine Learning training. Now I want to check to see if the results hit the "target range" or not. Lets say this range contains all values between -0.25 and +0.25. If it's inside this range, it's a Hit, if it's below Low and on the other side High.

            I now would create this three columns Hit, Low, High and calculate for each row which condition applies and put a 1 into this col, the other two would become 0. After that I would group the values and sum them up. But I suspect there must be a better and faster way, such as calculate it directly while grouping. I'm happy for any idea.

            Since C++17 the order of evaluation is specified such that the operands of = are evaluated right-to-left and those of << are evaluated left-to-right, matching the associativity of these operators. (But this doesn't apply to all operators, e.g. + and other arithmetic operators.)

            W/FlutterActivityAndFragmentDelegate(18569): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.

            To avoid that warning you just need to remove that API usage from your project. Remove these lines of code from the AndroidManifest.xml file.

            Previously, Android Flutter apps would either set io.flutter.embedding.android.SplashScreenDrawable in their application manifest, or implement provideSplashScreen within their Flutter Activity. This would be shown momentarily in between the time after the Android launch screen is shown and when Flutter has drawn the first frame. This is no longer needed and is deprecated – Flutter now automatically keeps the Android launch screen displayed until Flutter has drawn the first frame. Developers should instead remove the usage of these APIs. - source


            UPDATE (FLUTTER 2.8.0)

            As per the flutter 2.8.0 update, The newly created project doesn't have this warning.

            They removed unused API from Androidmanifest.yml but still have belove mentioned code.

            Run yarn run start to start the server at localhost:8000. It might take a couple of minutes for the server to start.
            The project requires some environment variables to be set to work properly. In the .env file a few things need to be set up:. Unless you need to use the shortener locally, you can leave these values blank. Otherwise, ask your backend engineer. If you are testing with a local backend, the values in .env.example match the default development configuration of the backend. Otherwise, your backend engineer should provide you with the configuration for the staging and/or production backend. n is an integer starting from 1. The numbers must be consecutive i.e. if you have 5 authentication providers, the numbers must be 1, 2, 3, 4, and 5. The following properties are used for the Playground Google Drive integration. You can leave them blank if you are not using or testing that feature locally. See here a guide on obtaining the above values from the Google API Console. The frontend can be configured to disable itself (based on user's system time) during certain periods e.g. during e-exams. Note that this is not foolproof, but it can be combined with other strategies e.g. taking down the frontend entirely (but this is needed to counteract the service worker).
            REACT_APP_BACKEND_URL: The base URL of the backend. If you are testing with a local backend, the value in .env.example matches the default development configuration of the backend.
            REACT_APP_USE_BACKEND: Set to false if not running together with the backend.
            REACT_APP_MODULE_BACKEND_URL: The base URL from which Source modules are loaded. (This is a js-slang feature, but of course it has to be configured here.) You can just use the default value in development.
            REACT_APP_SHAREDB_BACKEND_URL: The base URL of the ShareDB collaborative editor backend. The protocol must be HTTP or HTTPS (it will automatically be set to WS/WSS as appropriate). Must end in a trailing /.
            REACT_APP_URL_SHORTENER_SIGNATURE: The API key for the YOURLS URL shortener.
            REACT_APP_URL_SHORTENER_DOMAIN: The base URL of the YOURLS URL shortener. Unless you need to use the shortener locally, you can leave this blank. Otherwise, ask your backend engineer.
            REACT_APP_OAUTH2_PROVIDERn: The provider ID of the nth authentication provider. This must match the backend configuration.
            REACT_APP_OAUTH2_PROVIDERn_NAME: The name of the nth authentication provider shown on the login screen.
            REACT_APP_OAUTH2_PROVIDERn_ENDPOINT: The authentication endpoint of the nth authentication provider.
            REACT_APP_GOOGLE_CLIENT_ID: The OAuth2 client ID issued by Google.
            REACT_APP_GOOGLE_API_KEY: The Picker API key issued by Google.
            REACT_APP_GOOGLE_APP_ID: The project ID of the Google API project.
            REACT_APP_DISABLEn_START: The time from which to disable the frontend.
            REACT_APP_DISABLEn_END: The time until which to disable the frontend.
            REACT_APP_DISABLEn_REASON: Optional. A reason shown for the disablement.
            REACT_APP_PLAYGROUND_ONLY: Whether to build the "playground-only" version, which disables the Academy components, so only the Playground is available. This is what we deploy onto GitHub Pages.
            REACT_APP_ENABLE_GAME: Whether to enable the game. Off by default.
            REACT_APP_ENABLE_ACHIEVEMENTS: Whether to enable the incentives/achievements system. Off by default.
            REACT_APP_ENABLE_GITHUB_ASSESSMENTS: Whether to enable the GitHub Assessments feature. Off by default.
            There are a few additional environment variables that are used when building and deploying for production.
            REACT_APP_VERSION: A version string shown in the console on app launch.
            REACT_APP_ENVIRONMENT: An environment string. Currently it is only used to differentiate different deploys in Sentry.
            REACT_APP_SENTRY_DSN: The Sentry DSN for error monitoring.
            REACT_APP_SW_EXCLUDE_REGEXES: A JSON array of regexes as strings. The service worker will ignore paths matching any of these regexes. This is used in our GitHub Pages deploy so that it does not conflict with the subsites we host on GitHub Pages.
            REACT_APP_CADET_LOGGER: Log server URL. To test with cadet-logger on localhost, set it to http://localhost:8001/assessment-logger.
            REACT_APP_CADET_LOGGER_INTERVAL: The interval (in ms) that the frontend should upload logs.
