How can I get the data inside a beast::flat_buffer? Posted: 22 Aug 2021 08:36 AM PDT I'm connecting to a websocket using the boost/beast libraries and writing the data into a beast::flat_buffer. My issue is that I'm having trouble getting the data from buffer. I have a thread-safe channel object that I can to write to, but I'm not sure how to pull the most recently received message from the buffer. beast::flat_buffer buffer; // send through socket send_socket( ws, get_subscribe_string(trade_tickers, bar_tickers, quote_tickers)); // read into buffer while (channel.running) { ws.read(buffer); // need to write the most recently received message into the channel } I can write to the channel with channel.write(std::string arg). Any ideas on how to pull from the buffer?

Using py2app to create standalone application Posted: 22 Aug 2021 08:36 AM PDT I'm trying to create a standalone app to facilitate editing of photos out of this project which provides a GUI as well. I'm following all the steps described in the project's README.md and I can successfully launch the GUI and edit my photos. After that, when I follow the steps from py2app to create the application, setting the gui.py as main, the application crashes. Any help would be highly appreciated. I have worked with py2app in the past but not with such complex projects.

How do I make a role in Discord.JS that is a bit higher than other roles on the Role Hierarchy? Posted: 22 Aug 2021 08:35 AM PDT Sort of a follow up to my other question but, I am making a slash command that'd make a role with customisable permissions, customisable colours, and a customisable place up in the Role Hierarchy. I've seen that it isn't possible to make a role that is higher up on the Role Hierarchy if the bot is lower than the role you want to put it above, unless done by a member with MANAGE_ROLES and a high role but, is it actually possible to make the bot do this or not? Any ideas? P.S: I have seen bots that, upon invited, request that you put their role at the top of the list. I might make something like that for my bot.

How to use arabert-v2 completely offline? Posted: 22 Aug 2021 08:36 AM PDT I want to use the arabert-v2 preprocess offline. but it seems saving model is not enough for arabert preprocess function. What else should I download? any ideas? The git repository: https://github.com/aub-mind/arabert

Checking if User is Logged in via Express.js and Firestore Posted: 22 Aug 2021 08:35 AM PDT I am trying to determine if a user is logged in via Express.js and Firestore. The idea is to have the login/create user form displayed on the url path, '/'. However, if the user is logged in, then the app will redirect the user to the user's dashboard page. This would happen when the user logs in or creates an account. When I run my code I get the error TypeError: admin.auth(...).onAuthStateChanged is not a function I've realized that the admin package doesn't have onAuthStateChanged as that is something that only exists for the client-side. However, I was wondering how I would implement loading a different view depending on if the user is logged in or not from the server side? Is it even good for me to do this via the server-side or is there a better way for me to approach this? const admin = require('firebase-admin') ... app.get('/', (req, res) => { admin.auth().onAuthStateChanged(function(user) { // render user dashboard if user is logged in if (user) { getRestaurant('KOBmyfQEu4urNGgBTuiJ').then(data => { let ambassadorPromise = getAmbassadorInfo('KOBmyfQEu4urNGgBTuiJ') let activityPromise = getActivityFeed('KOBmyfQEu4urNGgBTuiJ') var restaurantName = data['name'] var totalScans = data['total_scans'] Promise.all([ambassadorPromise, activityPromise]).then(values => { ... res.render('dashboard', {restaurantName, totalScans, ambassadorList, activityList}) }) }) } // render account creation/login page is user is not logged in else { res.render('auth') } }); })

How can I change the position of an <hr> element? Posted: 22 Aug 2021 08:37 AM PDT I just started in web dev and my first project is a resume website. I am trying to separate the education and experience sections with an hr element. It was working, then I used the float property in CSS to align education descriptions to the left and corresponding dates to the right. Now, the line that came after the education section is in the wrong area. Here is some code: <section> <h2>EDUCATION</h2> <p id='e1'><strong>M.A. in Teaching</strong>, University of North Carolina</p> <p id='e2'><strong>June 2021 - May 2022</strong></p> <p id='e1'><strong>B.A., Human Development & Family Studies major & Education minor</strong>, University of North Carolina</p> </section> <hr> <section> <h2>EXPERIENCE</h2> The id e1 just floats left, and the id e2 floats right. How can I get the hr element to actually appear between the two sections, instead of in the middle of the education section?

NullReferenceException when raycasting in unity Posted: 22 Aug 2021 08:35 AM PDT I am trying to use a raycast that writes the name of the object that hits and the position and when shooting the ray it gives a null reference exception. It happens at this line Ray ray = cam.ScreenPointToRay(Input.mousePosition); Here is the code. using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { Camera cam; // Start is called before the first frame update void Start() { cam = Camera.current; } // Update is called once per frame void Update() { if (Input.GetMouseButtonDown(0)) { //a ray is created Ray ray = cam.ScreenPointToRay(Input.mousePosition); RaycastHit hit; //it is then casted if (Physics.Raycast(ray, out hit)) { Debug.Log("We have hit " + hit.collider.name + " " + hit.point); } } } }

Random sample of points on a region of the surface of a unit sphere Posted: 22 Aug 2021 08:37 AM PDT I need to generate a random sample of points distributed on a region of the surface of a sphere. This answer gives an elegant recipe to sample the entire surface of the sphere: def sample_spherical(npoints, ndim=3): vec = np.random.randn(ndim, npoints) vec /= np.linalg.norm(vec, axis=0) return vec (vec returns the (x, y, z) coordinates) which results in: I need to restrict the sampling to a rectangular region. This region is defined by center values and lengths, for example: center coordinates, eg: (ra_0, dec_0) = (34, 67) side lengths, eg: (ra_l, dec_l) = (2, 1) where (ra_0, dec_0) are coordinates in the equatorial system, and the lengths are in degrees. I could use the above function in the following way: call it using a large npoints, transform the returned (x, y, z) values into the equatorial system, reject those outside the defined region, and repeat until the desired number of samples is reached. I feel that there must be a more elegant way of achieving this though.

Private string becomes null when called from another method Posted: 22 Aug 2021 08:36 AM PDT I am making a 'Who Wants To Be A Millionaire' game.

Why is my app crashing while emulating on Android Studio (Kotlin Multiplatform) due to Null ImageView? Posted: 22 Aug 2021 08:35 AM PDT Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ImageButton.setOnClickListener(android.view.View$OnClickListener)' on a null object reference The line this points to is sleepButton.setOnClickListener() {makeCurrentFragmentS(sleepFragment)} where sleepButton is a button within a fragment that someone presses, to open another fragment within a frame layout.

vuepress2: how to get Vue instance so I can use third part vue plugin? Posted: 22 Aug 2021 08:37 AM PDT I am trying to use v-wave in VuePress 2 (the VuePress powered by Vue 3) I followed the docs, try to use the v-wave as a local plugin of the VuePress 2 .vuepress/config.js const vwave = require('path/to/v-wave.js'); module.exports = { plugins: [ (options, app) => { app.use(vwave); // the `app` is a instance of VuePress not Vue return {name: 'v-wave'}; } ] }; But it didn't work, because the app isn't the Vue instance but the VuePress. How can I install v-wave to make it work in VuePress 2? Thanks a lot!

Is there a way to change someDataGridViewCell.Style.BackColor (&etc) at any time? Posted: 22 Aug 2021 08:35 AM PDT Documentation says it must be done inside someDataGridView.CellFormatting event, but how can you pass the needed color information into it and force CellFormatting to be triggered when needed ? someDataGridViewCell.Value is working fine for changing cell text from a System.Windows.Forms.Timer Tick event, but I can't seem to change the coloring at the same time. In my case, all the columns are built and changed dynamically from user menus, and there can be dozens of them. This is VS2015. Update: My issue was I used Color.FromName() which returns Empty (transparent) for misspelled names -- very very bad for grid background colors. (I required coloring in data streams I was using so name seemed handy.) CellFormatting event used in most examples assumes you can derive the color information from the visible cell contents which is too limiting.

Use existing session cookie in gin router Posted: 22 Aug 2021 08:35 AM PDT I'm building a simple webserver in Go / Gin and I want to use cookies to create a persistent session that keeps a user logged in if they navigate away or navigate across several pages. Ideally, this is the flow: initialize router check for an existing cookie if a cookie exists, take the cookie token value if a cookie does not exist, create a new random token value initiate session with token value use session with router Code later on will verify if the cookie token value is expired and/or corresponds to an active user in the database. The most recent iteration I've tried is: router := gin.Default(); token_value := func(c *gin.Context) string { var value string if cookie, err := c.Request.Cookie("session"); err == nil { value = cookie.Value } else { value = RandToken(64) } return value } cookie_store := cookie.NewStore([]byte(token_value)) router.Use(sessions.Sessions("session",cookie_store)) But this fails because token_value is type func(c *gin.Context) string, and not string. I know there's something I'm missing here, and I'd love some guidance in how to resolve this issue. Thanks!

Convert a JavaScript string in dot notation into an object reference Posted: 22 Aug 2021 08:37 AM PDT Given a JavaScript object, var obj = { a: { b: '1', c: '2' } } and a string "a.b" how can I convert the string to dot notation so I can go var val = obj.a.b If the string was just 'a', I could use obj[a]. But this is more complex. I imagine there is some straightforward method, but it escapes me at present.
