Problem I have a Flutter canvas with zoom/pan functionality using Transform and GestureDetector. The issue is that tap detection only works within the original viewport boundaries, even after panning or zooming. When I scroll the canvas, taps on visible content outside the original window bounds are not detected. Specific symptoms: Only the first 4 rows are clickable initially If I shrink the window height, even fewer rows become clickable Taps are only detected within the original canvas viewport size Content that has been panned into view from outside the original bounds cannot be tapped Complete Code 1. Canvas Painter Widget class ShapeData { final ShapeType type; final String label; bool isStart; final Color color; ShapeData({ required this.type, required this.label, this.isStart =

I am having trouble with the delete function for my table items. It keeps returning a modal with a value of 1. I have tried many possible solutions I found online, but I still have no luck. Could you please help? Thank you in advance. Controller: public function destroy($id) { $articleCategories = ArticleCategory::findOrFail($id); $articleCategories->delete(); return redirect()->route('article_categories')->with('message', 'Article category deleted successfully.'); } Vue: <script> import Title from "../Layouts/Components/Title.vue"; import PaginationLinks from "../../components/PaginationLinks.vue"; import TableEditButton from "../../components/TableEditButton.vue"; import { router, useForm } from "@inertiajs/vue3"; import { ref, watch } from

I wrote an XDP program in C that saves every packet, except some blocked ones, into a ring buffer map, which is sent to userspace. I also made an xdp_loader program in C++ that loads the XDP program and attaches it to an interface. However, bpf_xdp_attach is undefined and I can't attach it. It's probably not even the right way to do it, but I'm honestly confused. I didn't find very good resources online, so I hope this will help. Here's my code: int Load(DatabaseManager &db) { const char *iface = GetInterfaces().c_str(); // choose your interface if (iface == "") { std::cerr << "No valid interface chosen" << std::endl; return 1; } struct bpf_object *obj; int prog_fd; obj = bpf_object__open_file("xdp_sniffer.o", nullptr); bpf_object__load(obj); blockedip_map_fd = bpf_object__find_map_fd_by_name(obj, "blocked_ips");

I am working with a dataset that contains a significant amount of noise and outliers due to measurement errors and real-world variability. The data includes numerical features and is used for a supervised learning task (classification/regression). I want to understand which machine learning models generally perform better on noisy data and why. Are tree-based models like Random Forest or Gradient Boosting more robust than linear models or neural networks in such cases? Also, what preprocessing or regularization techniques are recommended to handle noise effectively?

I am not a professional programmer, so my question might be "incomplete". I am tinkering with lwIP. I use Pico SDK 2.2.0 in VS Code. I send a http GET request of this form: http://dude.local/cgi-bin/handler.cgi?value1=5&value2=3, I can see that the request is sent properly (F12 in browser). Status code is 200. I want to use the two values (5 and 3 in my example query) within the pico, process it (in my demo application I just want to add the two numbers) and then respond with the processed result (in my case "8"). I had first tried it with a CGI handler, but it did not work (but I cannot recall what was the exact issue, however on the PC browser side, it always showed some "incorrect response" error). I thus now generally use "fs_open_custom" to react to that query. This ge

I'm trying to use EnergyCorrelator and Nsubjettiness packages from fastjet-contrib. My goal is to calculate these features on jets clustered from tower objects read from a .root file, within a PyROOT macro. However, I can't find a way to use them in Python. Below is my code: import fastjet def to_pseudojets(constits): return [fastjet.PseudoJet( c.pt * math.cos(c.phi), c.pt * math.sin(c.phi), c.pt * math.sinh(c.eta), c.pt * math.cosh(c.eta) ) for c in constits] def compute_nsubjettiness(constits, R0=1.0, beta=1.0): jets = to_pseudojets(constits) axis_def = fastjet.contrib.KT_Axes() measure_def = fastjet.contrib.UnnormalizedMeasure(beta) tau1 = fastjet.contrib.Nsubjettiness(1, axis_def, measure_def)(jets) tau2 = fastjet.contrib.Nsubjettiness(2, axis_def, measure_def)(jets) tau3 = fastjet.contrib.Nsubjettiness

The problem appears when i have a big amount of values in my pandas df.When i take 27 or 54 values(1 or 2 columns) it works normaly, but when i take more columns it gives me this erorr (i import gs class from another file.

I'm trying to have a set of custom VisualEffects in SwiftUI and call them at runtime, but I'm struggling with the type generics. Here's some really simple code of what I'm after, but the error is Type 'any VisualEffect' cannot conform to 'VisualEffect'. In a View I would cast as AnyView, but not sure what to do for effects. Any ideas how to solve this? protocol CustomEffect { func visualEffect(content: EmptyVisualEffect, proxy: GeometryProxy) -> any VisualEffect } struct EffectA: CustomEffect { func visualEffect(content: EmptyVisualEffect, proxy: GeometryProxy) -> any VisualEffect { return content .blur(radius: 10) } } struct EffectB: CustomEffect { func visualEffect(content: EmptyVisualEffect, proxy: GeometryProxy) -> any VisualEffect { return content .opacity(0.5) } } Here's the view using it.

I am a new python learner, and was using numpy to filter a array of fake information where its formatted in [name, products, price]. I was trying to see a way to filter the array if the products value is 10 or greater. I want it to be a new array with people who have more than 10 products. enter image description here

I'm building a photo upload component in SwiftUI where the entire rectangular area should be tappable to show a Menu with options (Photo Library / Camera). The problem: No matter what I try, the Menu popup always appears anchored to the TOP of the label, but I need it to appear at the CENTER of my tappable rectangle. Current behavior: Expected behavior: Menu should appear in the center of this area: My current code: import SwiftUI import PhotosUI struct PhotoUploaderExample: View { @State private var selectedImage: UIImage? @State private var showingImagePicker = false
