Comparing Floating Point Numbers, 2012 Edition
We’ve finally reached the point in this series that I’ve been waiting for. In this post I am going to share the most crucial piece of floating-point math knowledge that I have. Here it is:[Floating-point] math is hard.You just won’t believe how vastly, hugely, mind-bogglingly hard it is. I mean, you may think it’s difficult to calculate when trains from Chicago and Los Angeles will collide, but that’s just peanuts to floating-point math.Seriously. Each ti...

C++11 multithreading tutorial
The code for this tutorial is on GitHub: https://github.com/sol-prog/threads. In my previous tutorials I’ve presented some of the newest C++11 additions to the language: regular expressions, raw strings and lambdas. Perhaps one of the biggest change to the language is the addition of multithreading support. Before C++11, it was possible to target multicore computers using OS facilities (pthreads on Unix like systems) or libraries like OpenMP and MPI. This tutorial is meant to get you st...

Thoughts on Python 3
I spent the last couple of days thinking about Python 3's current state a lot. While it might not appear to be the case, I do love Python as a language and especially the direction it's heading in. Python has been not only part of my life for the last couple of five years, it has been the largest part by far. Let there be a warning upfront: this is a very personal post. I counted a hundred instances of a certain capital letter in this text. That's because I am very grateful for all the opport...

Kubernetes Authentication & Authorization 101
If we want to build a system with user modules, Authentication and Authorization are something that we can never ignore, though they could be fuzzy to understand. Authentication (from Greek: αá½θεντικÏŒς authentikos, “real, genuine”, from αá½θÎντης authentes, “author”) is the act of proving an assertion, such as the identity of a computer s...

OT Power Grid System Development
Use PLC to Remote Control Circuit Breaker in Power Grid System Figure-00: Project Overview Diagram, version v0.0.2 (2024) Project Design Purpose: The objective of this project is to demonstrate how to utilize Programmable Logic Controllers (PLC) to remotely monitor and control circuit breakers within a power (grid/supply) system. Using a Schneider Electric circuit breaker, sensor, closer and PLC, the project will cover the physical hardware connections and provide a step-by-step guide for desig...
Python FTP Server and Client
Distributed Log File Automated Archive System This week, we will introduce the automated compute cluster nodes' log automated archive system project and FTP Communication utility library module. Program Design Purpose: This project aims to create an FTP server & client lib program for file transfer and a files management system for log data synchronization. We will develop an automated log file archive system that regularly collects newly generated log files from multiple nodes in a compute...
A re-introduction to JavaScript
Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

2D Indoor CQB Robot Simulation
Program Design Purpose: The integration of robots in Close Quarters Battle (CQB) represents a significant advancement in modern military and law enforcement tactics. These robots, designed to navigate tight spaces, gather real-time intelligence, and engage threats, are invaluable assets in high-stakes scenarios. Our goal is to develop a 2D tactical board simulation system, similar to a computer game, that can load building floor blueprints, display CQB squad (robot) positions, enemy locations, ...
