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 […]
ERROR A new ZitaFTP Server update is available. It fixes a bug that literally prevents completely new users from trying it out. Here’s what went wrong…I thought I’d tested it thoroughly, testing both upgrading an existing installation and installing a new one. I tested the wizard in each case. Everything looked good, so ZitaFTP Server […]
After a very long delay, I’m pleased to announce that the next update to ZitaFTP Server has finally been released! The previous release was back in May. Let’s have a quick look at what’s inside…What’s New in ZitaFTP Server 1.16The big new feature is the internet (web) based configuration User Interface (UI). This allows both […]
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 […]
ERROR The next ZitaFTP update was supposed to be released yesterday. I was on track to finally get this long awaited and much delayed update finished, but then sickness hit. That left me with two choices: push on and suffer the consequences, or rest and get well as soon as possible. I chose the latter […]
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” […]
Last week I stumbled on a documentary about 5G. The title suggested that 5G will bring about catastrophe. So, I decided to watch it…It was easy to watch, thanks to good editing and pacing. The information about health risks identified for existing mobile technologies (including 4G, wifi, etc.) was interesting. I’d heard that new research […]
