I'm updating an Excel workbook that I've inherited and had to figure out if/when/where Functions/Subs were being called. Ran into instances where in the code I couldn't find it being called and deleted/comment out, only to have it run into an error later on since a button uses it. The code that f...

I am a beginner in assembly. But that didn't stop me from making a simple operating system completely made in assembly. It's very simple and doesn't do much. It's just a proof of concept. I would like to know what I can improve. And feedback would be great. bits 16 mov dl, 0 ; Cursor position co...

Just for fun I have written a Conway's Game of Life in cmd batch file. I like writing in batch - its restrictions and limits are its appeal. However - it is slow, very slow on a large grid. Any tips to speed it up? I think the slowest part is the function GETNCOUNT - this gets the count of the ...

As part of my ongoing development of a 3D game engine based on PyOpenGL, I am trying to do some refactoring to make working with textures and framebuffers as painless as possible. I feel this refactoring is needed so that my texture class can handle all of these (and more!) use-cases seamlessly: ...

I want to make an easy game where you drive a little block around a field. I'm not really sure how to get started with the graphics and the physics (collision physics mostly). Looking for some tips to start off. Also, would it be preferable to work in Java or Python for a project like this?

Consider this code segment: if (empty($_GET)) { $page_number = 1; } else { $page_number = $_GET["page_number"]; } I wonder if there is a better, more succinct way to express that idea. I thought about using a ternary operator, but the improvement over the original is not substantial: ...

I have an app with a product model. Each product belongs to a category. I also have a characteristic model, which represents the characteristics of a product (size, color, etc). I need to put these attributes in categories to group them. Should I add a new table (e.g CharacteristicCategory) or ...

In golang I am finding that there is a definite pressure in the language itself and built-in libraries to do things in a canonical way.

I managed to write a minesweeper clone in C++ console. I am curious to you thoughts, questions and things I could improve in the future, especially the objective part of the code. Thank you very much for your time! https://github.com/TheTask/MineSweeperClone

I decided to write a (more or less simple) C++ calculator; init.cpp generally gets most of the user input, and calls the functions. Here are my files: //init.cpp (main file) #include "includes.hpp" int main() { char t = '\t'; //tab character, used for menu formatting char nl = '\n'; //new li...

My question is to print all possible codes for the string. Assume that value of a=1, b=2, c=3, d=4, .... z=26. E.g. for “1123” possible codes are aabc, kbc, alc, aaw, kw Here's what I could come up with. private static void printCodes(String str, String ans) { if (str.length() == 0) {...
