A beta tester recently told me that ZitaFTP Server didn’t work on his Windows Home machine. It works fine on my Windows 10 Pro machine (and also Windows Enterprise), so we suspect that it might be a Windows Home specific problem. Remote debugging is a pain, especially with Windows services. However, I only have one […]
Almost all modern GPUs use the Single-Instruction Multiple-Thread (SIMT) architecture. With SIMT a group of threads (or wavefront) execute the same instruction in lock-step. Apart from making it a pain to program, it also means that when threads execute different code paths (e.g., if/else), the GPU must execute each branch one-by-one instead of simultaneously. This […]
Years ago someone asked me if I would add the ability to write shader assembly to the graphics drivers I was writing. My reply was: you really don’t want to do that. I’ve been working on adding switch support to Warp3D Nova’s drivers, and decided to explain why writing GPU code is hard: Modern GPUs […]
Daily journalling is a key part of how I keep my projects moving. Without it I’d be wasting time every day trying to remember what I was up to, and what I should do next. That wasted time quickly adds up. This is particularly true when I switch between projects (currently weekly).The ProcessHere’s what I […]
I’ve written multiple articles about eliminating waste in software development. This time, I’m going to delve into the biggest waste ever, which is:Writing software that nobody wants, or that you’re unable to sell.I’ve been there. Spending years writing software only to discover that nobody really wants it. And it hurt. A lot. Not earning money […]
A few weeks ago I decided to check out Raylib, an open-source game engine written in C. It’s different from other game engines such as Unity, Unreal, or Godot, because it has no editor to build levels and write scripts. Raylib has only the game engine core, and you build your game using that and […]
A few weeks ago I watched Ian Cooper’s talk titled “Test Driven Design (TDD) – Where Did it All Go Wrong?” In it, he suggests being more like a duct tape programmer (first time round). It sounded great, so I decided to try it and hit a snag almost immediately…Duct Tape ProgrammerA “duct tape programmer” […]
I just checked, and it’s been over 4 months since the last ZitaFTP Server update! The 5 month mark is approaching rapidly. I distinctly remember saying that I was aiming to have more regular releases after streamlining processes. So, what happened? Followers of this blog may recall my search for a C++ web framework to […]
If you’ve taken a programming course, the chances are that you’ve been told to write reusable code when possible. It certainly sounds great. Writing software is time consuming, so being able to reuse code instantly improves your productivity.I’m going to push back a little. Yes, code reuse is great. I reuse code; I use libraries […]
When I release software to testers, I don’t actually want them to send me bug reports. I want them to tell me that it’s working perfectly! Sadly, there’s no way to prove that code has zero bugs. And, given the complexity of the software we work on, bugs are simply a fact of life.I also […]
