I am using the video_player package in Flutter to play videos, and when switching to fullscreen mode, I see black bars on the sides or top and bottom. I want the video to fully fill the screen without these black bars, either by stretching or adjusting the aspect ratio properly: What I have tried: Using BoxFit.cover – This scales the video to fill the...

Given the following setup, N_r = 21; N_theta = 18; N_phi= 36; r_index = N_r-1; [phi,theta,r_sphere] = np.meshgrid(np.linspace(0,2*np.pi,N_phi),np.linspace(0,np.pi,N_theta),np.linspace(a,b,N_r)); X = r_sphere[:,:,r_index] * np.sin(theta[:,:,r_index]) * np.cos(phi[:,:,r_index]); Y = r_sphere[:,:,r_index] * np.sin(theta[:,:,r_index]) * np.sin(phi[:,:,r_index]); Z = r_sphere[:,:,r_index] * np.cos(theta[:,:,r_index]); rho = 1/r_sphere**2*np.sin(theta)*np.cos(theta)*np.sin(phi) I have set up my 2D X, Y, and Z coordinates converted from spherical coordinates, and a density variable in spherical coordinates that I...

I am trying to install some packages upon newly created conda environment. But weirdly it is already full of packages, which have been used in other previous conda environments. For example, I noticed var conda environment already share the packages with other environments although I never asked to - I used conda create --name var -y python=3.10 command: (base) XXX@XXX-XXX:/home/nas/XXX/B/C$ conda activate var (var)...

How can implement dark mode in TailwindCSS v4 using Vite in React project? I did the below code but it didn't work? vite.config.js import { defineConfig } from 'vite' import react from '@vitejs/plugin-react' import tailwindcss from '@tailwindcss/vite' // https://vite.dev/config/ export default defineConfig({ darkMode: "media", plugins: [ react(), tailwindcss(), ], })

Here is the structure of DEA in my book. I have to construct a Regular Expression for it. I do not understand 1 thing. First of all, we have to construct steps: Then we simplify it in math. format: Eventually, we substitute etc. In my book, the L3 is simplified but I cannot figure it out, how exactly it was simplified... Can someone please...

When using TailwindCSS 3 in a Next.js app you could console log the theme in layout.tsx when you were implementing a tailwind.config.ts: import resolveConfig from 'tailwindcss/resolveConfig'; import tailwindConfig from '../../tailwind.config'; const { theme } = resolveConfig(tailwindConfig); console.log({ theme }); Since TailwindCSS v4 is going away from the config and using a CSS-first approach and tailwindcss/resolveConfig doesn't seem to be present how could someone in...

I am using Jest in my React module and encountering an error where it cannot find the classes for SVG elements like SVGPathElement and SVGPolylineElement. The specific error message is: ReferenceError: SVGPathElement is not defined Here is the sample code that reproduces the issue: import '@testing-library/jest-dom'; class MyClass extends SVGPathElement { } it('first test', () => { }); I have defined several prototypes for...

I’m looking to create a line chart which shows, for each day, the age of all tickets (I have jira ticket created date and ticket status resolved available). I need to show the max ticket age, the min ticket age, the average ticket age. E.g. if the max ticket age is an outlier of 1350 days old today then today will have 1350 days...

I have a Redis Cluster spanning multiple data centers. Initially, the number of nodes in each data center was different. However, during a network partition, the cluster was split into two parts, and due to the failure pattern, each partition ended up with the same number of nodes. Now that the network has recovered, I'm trying to understand how Redis Cluster consolidates the data.

I'm using CodeBERT to compare how similar two pieces of code are. For example: # Code 1 def calculate_area(radius): return 3.14 * radius * radius # Code 2 def compute_circle_area(r): return 3.14159 * r * r CodeBERT creates "embeddings," which are like detailed descriptions of the code as numbers. I then compare these numerical descriptions to see how similar the codes are. This works...

I have a large .xlsx file (180 MB, containing 300K lines with 150 columns each) I need to perform some operations within. I am having problems with loading this file (OutOfMemoryError), as POI has a large memory footprint on XSSF (xlsx) workbooks. I checked java.exe memory usage, it increases linearly to 17 GB and after that it becomes stale. In this line : XSSFWorkbook...

I have a situation where I have a templated class that contains a tuple. The elements must be initialized (they all have compatible constructor), but cannot be moved. Simplified code showing the problem: #include <tuple> struct A { int i{}; A(int i) : i(i) {} // This causes a compile error in the tuple constructor: A(A&&) = delete; }; struct B { int i{};...

I'm trying to fetch the full error responses from a Qualtrics API response with httr2, however, the error-catching from httr2 itself fails because the error response body is not what httr2 expects. My problem is twofold: When running the API call, it errors (rightly so), but doesn't create an R object from where I can fetch the error information. I solved this problem by...

I'm guessing 'billing export to bigquery' is stopped around February 3rd. But i would like to know the exact time when does it stopped. I tried to check it using logs explorer but it failed.

I've been trying to follow the code/examples in How to disable logging images in nginx but still allow the get request?, but so far have not been successful in limiting the entries in the NginX access log. My goal it to not "clutter" up the access log with entries for images which are displayed in my web pages. Here are the relevant sections from...

For some reason I'm getting an error in inRange saying that overload resolution failed, upperb is not a numerical tuple. Expected Ptr for argurment 'upperb'. I don't understand why lowerb works but upperb doesn't. colorSorter.py import cv2 import numpy as np from util import get_limits yellow = [0,...

Suppose I have an RGB24 image in which the color of each pixel evenly encodes a (raw) data byte. Scheme: Channel red encodes Bit 7:6 (R: 0-63 = 0b00, 64-127 = 0b01, 128-191 = 0b10, 192-255 = 0b11) Channel green encodes Bit 5:3 (G: 0-31 = 0b000, 32-63 = 0b001, 64-95 = 0b010, 96-127 = 0b011, ...)

I was working on practice problems for a job-interview, and I came across this problem that stumped me. The Problem The task is to reconstruct a string of a specific length from a probability distribution of substrings of length L. Given: L: Length of substrings n: Length of the output string p: A probability distribution over all possible length-L substrings A dictionary mapping each...
