Introduction Problem decomposition is a technique that breaks down complex problems into smaller subproblems. It’s widely used in computer science, engineering, and mathematics. Breaking down a problem into smaller parts simplifies the understanding and resolution process, helps us recognize problem elements and interconnections, and enables prioritization and tackling of subproblems. What Will You Learn? The fundamentals of problem decomposition. Steps to effectively decompose a problem. Types of decomposition methods. Examples of problem decomposition. Tips and best practices for successful decomposition. What Are The Fundamentals of Problem Decomposition? Effective problem decomposition follows these principles: ...

If you need to configure your shell environment, review this shell scripting tutorial. It’s a solid starting point for configuring your a environment. I’m here to share how I configure my shell environment. I configure my macOS shell environment in the following ways: I use the best package manager Homebrew, to install and manage software packages.

AI has changed everything. In my teens, computers were budding into usable technology. I traded my Sega Master System for a 286 computer with a 40MB hard drive to play Eye of the Beholder. It wasn’t long before I realized I needed an upgrade, and I bought a 486 on credit with 4MB of RAM and a 200MB drive! I upgraded to 8MB of RAM to play Ultima VIII: Pagan and hit the big time while breaking the bank. ...

Technical overconfidence has become a functional requirement in technical discussions. I used to be quiet, but now I must demonstrate profound confidence. While developing software, my primary goal includes serving user needs. In the past, software development meant living a quiet life with few interruptions. To avoid dealing with people explicitly, I switched from technical support to software development early in my career. Oh, how the world has changed, but it’s mostly better now. There are often cost overruns in software projects because programmers still spend months coding in isolation. ...
