Programming Definition and 1000 Threads

It has been over 15 years since I completed a Masters of Science in Electrical Engineering. However that alone does not really date me much. So far I have yet to find a source of employment that lasts long enough or is of enough compensation to pay off student loans before I can even begin to...

I'm trying to code a script for a character in my game. This will tell the character if the player is in front or behind them. Basically I know the coordinates of the character and their angle of rotation (if rotated 45 deg, that is where they are looking) Perpendicular to their angle is a...

So I'm trying to teach myself C++ programming and I'm having trouble writing a password program. Essentially I want to program to ask the user to input a password, and then compare that input with the correct password. If the user input matches the password I want the program to output a message...

Hey, this is my first time posting and I've been looking everywhere but can't find a decent water model. I hacked a program together to decently simulate water physics, but it's not nearly robust enough for what I need. So, in this world, everything is based on a grid. Any non-wall tile can...

Where can I learn to break the habit of using time steps and instead use mathematical frameworks to preserve time symmetry when programming simulations? I recently visited a site ( bugman123.com ). He's got a lot of STEM experience. He's written simulations and programs for a lot of things...
