I have multiple pre-compiled dynamic libraries that use the same extern "C" methods names. The methods can behave differently for each dynamic libraries. Ultimately these methods will be accessed in a SystemVerilog simulation via DPI (Direct Program Interface). When trying to link all the librari...

So I'm trying to read data and store it in an array as fast as possible and the fastest method I found of doing so was this. var filePath = "data.dat"; FileStream fs = new FileStream(filePath, FileMode.Open); bool[] buffer = new bool[fs.Length]; TimeSpan[] times = new TimeSpan[500000]; Stopwatch...

Tic-Tac-Toe from scratch. Code Ugliness check before I implement the win-condition and maybe get set in to bad habits. Questions: As implemented: Better to pass board between functions or set as a global variable? OK to use same variable name within different functions? OOP: Would you recommend u...

Contexte Postgresql has an INHERITS keyword which lets you inherit one table from another, but it is known to have several caveats, mainly because it is not a true column-based inheritance. I implemented a working solution using views and rules, detailed below, and I'd be glad to get some feedba...

A few days ago I requested a review of my functools extension library. Since I did not have any unit tests for it, I started writing some for the revised version of this library. I'd like some feedback on whether these tests are sensible and how they may be improved upon. Revised library (test su...

In my application (rails 6.1.4), I'm using pay gem. Everything is set up fine, but only thing remaining is to listen to the webhook on when a charge has been successful to update the order/table. In their docs, they already have webhooks ready and I just need to listen to them. This is what they ...

I have this tool for permuting bits in BitSets: com.stackexchange.codereview.util.BitPermutation.java: package com.stackexchange.codereview.util; import java.util.BitSet; import java.util.Objects; /** * This class is responsible for representing the bit permutations of * {@code long} values....

Could someone please review my stored procedure? I have two questions. Is it correct to use updlock, readpast with UPDATE query? In my past I have not used any hint with UPDATE, I have used nolock only with SELECT. Is this correct to use IF XACT_STATE() <> 0 to rollback? I have also not used th...

I've got this code, to display the current text cursor position of the last printed character on the terminal screen. It's using ctypes to get the (old non VT) Windows API, for this. However, I feel the code is a bit too long and not very transparent regarding what is going on. #!/usr/bin/env pyt...

I'm relatively new to programming, as in my second semester of college. To practice C, I started work on a chess game. I'm wondering if there are ways I could improve my code, make it look more professional, or reduce some blocks of inefficient code. I have more ideas on things to add to the game...

The minimax algorithm isn't working, it always picks the last move, I've been trying to figure it out but I just don't understand it. I expect the problem to be in any of the following functions: game_loop(), best_move(), minimax(). import time import pathlib import pygame pygame.font.init() # -...

Given a number as a string, no leading zeros, determine the sum of all integer values of substrings of the string. Given an integer as a string, sum all of its substrings cast as integers. As the number may become large, return the value modulo 10**9+7. Example: n='42' ans=4+2+42=48 Full problem:...

first post ever on a stackexchange website. Pardon any mistakes. I've tried to write an event dispatcher for a GLFW/Glad library however I am not very used to writing efficient code (Spent the majority of my life writing in C# and performance was never really the focus of what i learnt in univers...

I have a legacy project that has a lot of linkage done using #pragma comment(lib, "libname.lib"). Moreover, some projects define linker directives in mixed ways - this is very frustrating and inconsistent. There are over 100 projects in the solution, so I don't want to even try to fix them by han...
