I'm making a site and it has 3 index files as of now, but one of my index file isnt working with the hover in CSS I gave it, it has the same class with no changes, but nth works. I double-checked the CSS and nth worked. Is it my HTML?

I'm trying to join an ACS Room call using the JavaScript Calling SDK. The room is created successfully, participants are added via the Rooms REST API, but when calling callAgent.join({ roomId }), the returned call object stays in "None" state indefinitely. SDK telemetry reveals roomJoin: false and IsGroupCall: true, suggesting the SDK isn't recognizing the join attempt as a room call despite using the correct locator format. I've tried AI (Codex and Claude Code) but no success figuring it out. I seem to be going in circles on this now and could use some human insight. Environment: @azure/communication-calling: 1.40.1 @azure/communication-common: 2.4.0 @azure/communication-rooms: (backend, latest) Platform: React + Vite, deployed to Azure Static Web Apps

I'm implementing hidden line removal for a 3D wireframe renderer using HTML5 Canvas 2D. When rendering a solid object with wireframe overlay, edges behind solid faces should be hidden. Drag to rotate. Toggle "X-Ray" to see the difference between with/without hidden line removal. The hidden line removal is not working correctly - edges that should be hidden are visible, and edges that should be visible are sometimes hidden. Approaches I've Tried 1. Depth Buffer Simulation Create an offscreen canvas as a depth buffer, render front-facing faces with grayscale values encoding depth (darker = closer), then sample points along each edge and compare depths: function drawFaceToDepthBuffer(verts, nearZ, farZ) {   for (let i = 1; i < verts.length - 1; i++) {     const v0 = verts[0], v1 = verts[i], v2 = verts[i + 1];     const avgZ = (v0.z + v1.z + v2.z) / 3;     const normDepth = (avgZ - near

I have a product schema. Each product will have default fields: title, price, stock, description, and category. Depending on the category (clothing, technology) selected from the front end, I send additional fields: clothing: sizes: [String], gender: String, colors: [String], typeClothing: String, technology: brand: String, techType: String The problem I'm having is that when I send a technology product, which doesn't have sizes or colors in the database, these values ​​are saved as empty arrays. I understand this is because their data type is an array of strings. How can I prevent this? Adding `default: undefined` worked for me, but I'm not sure if this is correct.

I have a vectorized (ensemble) Q-network implemented using Flax Linen that works as expected. Each critic in the ensemble has separate parameters, and the output is stacked along the first dimension (n_critics). I am trying to port this implementation to Flax nnx, but I am struggling because nnx.vmap does not have the same API or semantics as flax.linen.nn.vmap. In particular, I am unsure how to correctly create an ensemble of nnx.Modules with independent parameters. import jax.numpy as jnp from flax import linen as nn from typing import Optional class QNetwork(nn.Module): action_dim: int rew_dim: int hidden_dim: int = 256 @nn.compact def __call__(self, obs, w, deterministic: bool): x = nn.Dense(self.hidden_dim)(obs) x = nn.relu(x) x = nn.Dense(self.action_dim * self.rew_dim)(x) return x clas

My computer had a black screen saying "Couldn't connect to the network," and it wouldn't start, so I had to restart my OS, removing all of my apps but retaining most of my files. After I reset my computer, only TDM-GCC was still there, so I just reinstalled VSC. When I tried to run a program in C++ that I had made, it gave me the following error: "PS C:\Users\thebe\OneDrive\Fortran Projects> cd "c:\Users\thebe\OneDrive\Fortran Projects\" ; if ($?) { g++ something.cpp -o something } ; if ($?) { .\something } g++ : The term 'g++' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:60" I knew the g++ function had something to do with TDM-GCC, so I figured that it was the issue. All of my extensions were already there when I reinstalled VSC, so it couldn't hav

Using this regex: // Match plural words (cats, dogs, boxes) - including words ending in x/ch/sh which add 'es' $pattern = "/^[a-zA-Z]+(s|es|xes)?$/"; Can I apply this as a suffix on $_POST['USER']? A suffix is the end of a string, like a namestring for example. So in Stanley's ' and s are suffix

I get this error when trying to launch my spring boot application on IntelliJ at the build : java: java.lang.ExceptionInInitializerError com.sun.tools.javac.code.TypeTag :: UNKNOWN The jdk installed is the jdk 25 but the project is set to java 21. I made some research i find that the problem is linked usually to lombok and try differents solutions, but still can't resolve the problem. I try to compile the project using mvnw but i get this error : ./mvnw clean install The JAVA_HOME environment variable is not defined correctly, this environment variable is needed to run this program. Or the JAVA_HOME is correctly set in my environments variables. Here is a part of my pom.xml : <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi=
