I use github.com/diamondburned/gotk4/pkg/gtk/v4. I'd like to create a modal dialog, like this: dialog := gtk.NewMessageDialog( &window.Window, gtk.DialogModal|gtk.DialogDestroyWithParent, gtk.MessageInfo, gtk.ButtonsOK, "Some info I want to let the user know", ) dialog.SetTitle("Information") dialog.SetVisible(true) Only, NewMessageDialog() is declared like this: func gtk.NewMessageDialog(parent *gtk.Window, flags gtk.DialogFlags, typ gtk.MessageType, buttons gtk.ButtonsType) *gtk.MessageDialog Unkike the C function gtk_message_dialog_new(), the Go one doesn't have the message_format argument, nor the ... (parameters for message_forma

Here is a permutation generator which takes a whitespace-delimited list of strings on stdin: echo a b c | perl -aE ' sub p { @_ && # <-- why is this line needed? map { my $f = $_[$_]; map [$f,@$_], p(@_[0..$_-1, $_+1..$#_]); } 0..$#_ } say "@$_" for p(@F) ' and outputs the permutations: a b c a c b b a c b c a c a b c b a @_ can never have fewer than zero elements $#_ will be -1 when @_ is empty map { ... } 0..-1 performs no iterations So it seems to me that the explicit test that @_ is not empty is unnecessary - when there are no arguments, the map should not run. However, if I remove the check, the code produces no output. I don't understand why. Enabling strict complai

The Arsenal’s championship win inspired me to create a C# console application as a practice exercise. Currently, everything is contained in a single file. I would like to know how the project structure should be properly organized. What is the best and most correct approach for this? For example, is it good practice to separate the code so that one file contains the data model and another contains the application logic? Here is the code: using System; using System.Collections.Generic; using System.IO; using System.Linq; namespace ConsoleApp1 { public class Player { public string PlayerId { get; set; } public string Name { get; set; } public int BirthYear { get; set; } public string Nationality { get; set; } public string Position { get; set; } public string ClubId { get; set; } public string ClubName { get; set; } public int ShirtNumber { get; set; } p

I have to check if the generation of Rust sources files from YANG files is working the way we are expecting it to do. According to the crate information below, I have to put my YANG files into a yang-models directory, and a cargo build will handle the generation, provided rustnetconf_yang is a dependency of the project: rustnetconf-yang YANG model code generation for rustnetconf. Generates typed Rust structs from YANG models so your network config is validated at compile time. How it works Place .yang model files in your project’s yang-models/ directory Add rustnetconf-yang as a dependency Run cargo build — the build script generates Rust structs in OUT_DIR Use the generated types with edit_

My UI button in unity doesn't work on the thor. I am using unity 6000.3.13f1. I have tested multiple ways of trying to fix this but couldn't come up with the correct sollution. However I have found that it does reconize where I touch the screen for both the top and bottom screen this works. (testing with unity remote and also making builds) I did find a half workaround, but this somehow only works for the top screen. (by simulating a click when a press is shorter than .2 seconds) anyone who could help me further with this?

I am writing UI integration tests for a Jetpack Compose Android application using the Firebase Firestore Emulator hosted on a local test server. I want every single test case to start with a clean slate. Before each test runs, my local server populates the Firestore emulator with specific test data so that every test begins with the exact same database state. The Problem Running tests individually: If I run each test case manually one by one, they all pass Running tests in a suite (together): If I execute the whole test class / group, the tests start to fail. The UI displays old data belong to the previous test case, even thought I verified that the Firestore emulator itself contains the correct, newly populated data. It seem like the App is caching the data locally on the dvice between test runs, meaning the UI reads from the locale cache instead of fetching the fresh data from the emulated firestore database.

Triggered by this question I was reading about out of bounds access via std::span::operator[] here: If idx < size() is false, the behavior is undefined.(until C++26) Why is it specified explicitly to be undefined? With std::span s{ptr,size}; I see two cases: The underlying array has only s.size() elements, attempting to call s[s.size()] is undefined, because ptr[size] is undefined. That span::operator[] is specified to be undefined does not actually change that. The underlying array has more than s.size() elements. In that case s.data()+size can be dereferenced without problem, yet s[s.size(

I have two different Simple Subscription products. When I add both products to the cart and complete the checkout, WooCommerce creates a single subscription containing two line items. However, I need WooCommerce to create two separate subscriptions—one subscription for each Simple Subscription product purchased. Can you suggest a custom code solution or a plugin that can achieve this behavior? WooCommerce Version: 10.7.0 WooCommerce Subscriptions Version: 8.7.1 Product Type: Simple Subscription Monthly billing No trial period No sign-up fee Example: Product A (Monthly Subscription) Product B (Monthly Subscription) When both products are added to the cart and checkout is completed, WooCommerce creates: Subscription #100 Product A Product B Required: Subscription #101 Product A Subscription #102 Prod

For those working with JavaScript whether client-side, server-side, or both how much of a necessity is TypeScript in 2026? I keep seeing videos and forum threads where developers swear they'll always reach for TypeScript whenever JavaScript is involved. But how true is that in practice, on an actual job? Is it just hype ?

I want to delete a record from the selected table using an SQL query, but first I want to check whether any value is associated with that record. To do this, I need to use this validation in the SQL query ? if (result.length > 0) { return res.status(400).json({ "message": "The record cannot be deleted!" }); }
