I’m a DevOps architect, musician, animal lover and all-round geek. If it’s got shiny lights on it, makes loud noises or purrs/wags its tail when you stroke it, I’m all for it.

| Step | Action | What you listen for | | :--- | :--- | :--- | | 1 | Run the car empty at contract speed. | Scratch frequency: A scratch per belt rotation indicates a localized belt defect. | | 2 | Run the car with partial load (50% capacity). | Worse with load = belt slippage or sheave groove wear. | | 3 | Visually inspect belts stopped. | Look for "shine" (polyurethane dust) or visible steel cables. | | 4 | Check the sheave grooves. | Use a flashlight. Any pitting, rust, or glazing indicates a problem. | | 5 | Measure belt tension (Otis spec: 250-350Hz). | Uneven tension causes belts to "walk" sideways, creating a scratch. |

Stop Breaking TLS

Rant ahead: I hate TLS “Inspection” software with a burning passion and I wish we collectively as an industry would just knock it the fuck off and stop pretending it’s some great security benefit. Every time I encounter it, in whatever form, it’s a gigantic headache that makes everyone’s life worse off and as far as I am concerned offers next to zero tangible benefits.

AmigaGuide Reference Library

As I slowly but surely work towards the next release of my setcmd project for the Amiga (see the 68k branch for the gory details and my total noob-like C flailing around), I’ve made heavy use of documentation in the AmigaGuide format. Despite it’s age, it’s a great Amiga-native format and there’s a wealth of great information out there for things like the C API, as well as language guides and tutorials for tools like the Installer utility - and the AmigaGuide markup synta...

Disqus - An Apology

Earlier today, I got an email alerting me to an angrier than usual comment on this website. It was a proper keyboard warrior rant accusing me of all sorts of misdeads revolving around “forcing ads down people’s throats”. I replied saying that there had never been any ads on this site, never will be and I detest the enshitification trend of the modern Internet too. I also have found much of today’s web unbearable without tools such as Pi-Hole and a VPN; I use Firefox with...

Amiga Systems Programming in 2023

If you ever get a chance to look through the classic Amiga OS source-code still floating around some murky corners of the internet, it is a thing of beauty and astonishing capabilities. It’s an inspirational piece of computing history with unmatched capabilities for the time. Remember, this was all on a computer released in the 1980s with 512Kb memory, a 7Mhz 68000 16-bit CPU, and a single floppy drive with 880Kb storage. On these limited specs, AmigaOS provided a pre-empt...
