Currently, my task is to create special numbers based on customer requirements and then sell them at different prices. Examples include: Quadruple digits: 1111, 2222, ... Sequential numbers: 123456, 234567, ... Palindromic numbers: 123321, 234432, ... I use regex to find these numbers (from a pre-generated list of 4-6 digit numbers). Now, I'm having difficulty with a specific pattern that consists of 6-digit numbers...

int main() { uint8_t bytes[] = {0, 126}; uint8_t *pointer = bytes; printf("Hex: %x", (*(uint16_t*)pointer)); } output Hex: 7e00 Why is output 7e00 ? shouldn't the bytes array look like this in memory 0x00 0x7e ? and when telling C to cast pointer to uint16_t* and print what it's pointing to I expect it to print 007e. But that wasn't the case!

I am working on a task to find the largest independent set in a graph. After researching various approaches, I found that backtracking is often recommended, but it has exponential time complexity, leading to a significant state space growth. To optimize my solution, I implemented a greedy approach with a slight variation. I represented the graph using an adjacency list and sorted the vertices...

I am on popos using gcc 11.4 The commands I tried: g++ -fopenmp-simd -O2 -S simd_reduction.cpp g++ -fopenmp-simd -O2 -mavx2 -march=native -S simd_reduction.cpp The code: #include <omp.h> float dot_product_simd(const float a[], const float b[], int n) { float dot = 0.0; #pragma omp parallel for simd reduction(+:dot) for (int i = 0; i < n; i++) { dot += a[i] * b[i]; } return...

Follow-up question to this question, where single argument use was not solved. Assume the following C++ concept: template <typename T> concept has_set = requires(T t, std::string s) { { t.set(s) } -> std::same_as<void>; }; }; I cannot use a concept for parameter s, e.g. template <typename T> concept has_set = requires(T t, std::convertible_to<std::string_view> s) { { t.set(s) } -> std::same_as<void>; }; }; will fail...

I am using Oracle database with AR8MSWIN1256, and unfortunately I cannot change the encoding to UTF8. Then I have defined a table with a column type of varchar2 and tried to run sql operations from a Java application. Based on the character set of windows-1256 it is possible to save characters like ی, that has encoding code EC and its table is mentioned in...

I'm implementing a Physics-Informed Neural Network (PINN) to solve a 2D elasticity problem, comparing results with FEM analysis. While most parameters (ux, uy, sigma_yy, sigma_xy) closely match the FEM results, the sigma_xx predictions are significantly off. import torch import torch.nn as nn import torch.optim as optim import matplotlib.pyplot as plt import numpy as np from matplotlib.path import Path import pandas as pd from torch.optim.lr_scheduler...

I'm working on a project where I display a series of YouTube videos stored in a JavaScript array retrieved from my database. Each video has a known orientation (portrait or landscape). I've made some adjustments to my CSS to ensure that the videos utilize the full viewport without any margins, as shown below: .fancybox-content { width: 99.1vw !important; height: 99.1vh !important; } .fancybox-slide {...

I'm trying to make a physics engine in javascript using not the usual canvas with vertices but instead used only svgs, and i've reached a point where I need to compute the normal vector at the collision point which is quite easy using this piece of code: let dx = 0.001; let after = a.getPointAtLength(i + dx).matrixTransform(a.getScreenCTM()) let before = a.getPointAtLength(i - dx).matrixTransform(a.getScreenCTM()) arr.push({x:...

An external system has a requirement that anyone accessing it should prefer TLS 1.3. How can I make my Java desktop application prefer TLS 1.3? I'm at Java 17, and TLS < 1.2 is disabled using jdk.tls.disabledAlgorithms. From a search it seems that jdk.tls.client.protocols might be the desired system property, but is it somehow in "preferred order"? E.g., if I try the following: jdk.tls.disabledAlgorithms=SSLv3,...

This seems to be a super basic question but I can't seem to find the answer. I am trying to set a nullable decimal to 1 but I always get a null reference exception with "xxx.HasValue" was null. I have something like this: public void Test() { decimal? xxx = 1m; } Surely this should work! What am I missing? This is using .NET...
