It’s the layered software and execution model built around the GPU: Together, these form one of the most influential computing stacks of the last two decades. From Graphics Card … Read more

Violence facilitates change.

by

It moves things.Breaks things.Forces outcomes where none seemed possible. But let’s not dress it up. Violence doesn’t open doors. Violence breaks them down. Splinters the frame.Shatters whatever was holding things together. And it doesn’t just break structures. It breaks people. Communities that took generations to form.Families that don’t come back together.Lives that are never lived. … Read more

Good Days Are Built, Not Found

by

Some days don’t arrive as “good days”. They just… arrive. A bit flat.A bit heavy.Like you’re already behind before you’ve even started. And there’s this quiet expectation — that somewhere in the day, it should turn.That something will click and suddenly it becomes a good one. But more often than not… it doesn’t. It just … Read more

The Carry Forward Principle

by

I don’t think I realised how much energy I was wasting starting over every day. Not physically. Mentally. Every morning had this quiet reset baked into it: And before that, even earlier, there was another version of it: “The sun will come up tomorrow, and it won’t be nearly as bad as you think.” That … Read more

AI Assistants Compared — Architecture vs Marketecture

by

Executive Summary The current wave of “AI comparison charts” (ChatGPT vs Gemini vs Claude vs others) are not wrong—but they are not reliable. They conflate: This article reframes the comparison using: The Core Problem Most comparisons: 👉 Example flaw:“Perplexity = best for research”→ In reality, it is a retrieval + UX layer over models, not a … Read more

This Old Dog Is Still Learning Old Tricks

by

I’ve been working with UNIX/Linux for 30–40 years. You’d think by now I’d have seen every trap. Turns out — some of the oldest ones are still the sharpest. The Setup I’ve got a simple media pipeline: Except… the disk wasn’t mounted when I first built it. Linux didn’t complain.It just quietly wrote everything to … Read more

Falling Off the Wagon

Morning numbers:B6.8 / K0.1 – Ketones need to be above 1.0No glucose detected. Not terrible. Not great either. Yesterday was a good reminder of something easy to forget. Made muffins.Off-the-shelf mix.Licked the bowl like a 8-year-old.Picked at the crumbs after they came out. Breakfast was baked beans.Then a couple of stolen chips off a plate.Kumera. … Read more

Do You Believe — Are There Aliens Out There?

by

It’s one of the oldest modern questions. Not whether something strange has been seen,but whether anything is actually out there. Not stories.Not lights.Not interpretations. But intelligence. The Scale Problem Start with the numbers. There are hundreds of billions of galaxies.Each with hundreds of billions of stars.Many of those stars host planets.Some of those planets sit … Read more

Breaking 90kg

by

What Actually Changed. There’s something psychologically significant about seeing the scale start with an 8 again. Not because 89-point-something is some grand final destination. It isn’t. But because it marks a boundary crossed. Proof that change is no longer theoretical. Proof that momentum is real. This morning the number was 89.65kg. And that matters. Not … Read more

Westall UFO — Memory, Mystery, and Meaning

by

Some stories refuse to die. Not because they were proven, and not because they were explained, but because they landed somewhere deeper than facts alone. The 1966 Westall UFO incident sits in that category. A schoolyard. Broad daylight. Students and teachers. A strange object. Confusion, excitement, disbelief, and then, over time, the slow hardening of … Read more
