Page: Feed: --- ## [The High-Performance Team Simulator Guide](https://notionparallax.co.uk/2026/team-simulator-guide) _2026-08-14 · Notion Parallax_ This is another completely AI generated post. I’m going to work through it and probably do a bunch of rewriting as I play around with these ideas. This is a working guide for using games — video, tabletop, and DIY — as a low-stakes sandbox for the specific communication habits that make teams reliable under pressure: closed-loop confirmation, shared mental models, and blameless debriefs that… ## [Manufactured Incompetence](https://notionparallax.co.uk/2026/manufactured-incompetence) _2026-07-24 · Notion Parallax_ This is still early days for this. I’m in the middle of editing, I’m trying out a new way of writing essays with AI rather than doing it all solo, or all AI. There’s a LOT to do here, but we’re getting there. We are busy in order to have leisure. — Aristotle, Nicomachean Ethics A scenario: A senior person is handed a difficult idea. They read the first page, skim the rest, and conclude that the… ## [Book Analysis Revisited](https://notionparallax.co.uk/2026/book-redux) _2026-07-08 · Notion Parallax_ Back at the end of 2019 I did some analysis of the books I’d been reading , and it wasn’t an especially diverse experience. I used a pretty clumsy method but it worked a bit to give me some insight. As a result of that I had a crack at trying to read more diversely , which was really enjoyable, but surprisingly difficult to get the full bingo card, but I stuck with it for a few years. Then I… ## [Catalytic Hydrogen Rebreather (CHR): Concept Proposal](https://notionparallax.co.uk/2026/catalytic-hydrogen-rebreather-concept-proposal) _2026-06-13 · Notion Parallax_ Table of Contents The Problem Being Solved Background: Hydrogen Diving History The Key Constraints: ICD and Combustion The Proposed Architecture Gas Management Strategy Feasibility Analysis: ICD and Scrubber Rate Representative Dive Profiles Engineering Challenges Prior Art Open Questions References 1.

Naïve me thought that if 50% O₂ got me to the surface in x minutes, then 100% O₂ would get me there in half the time, but that’s super wrong. You can use a leaner mix at a deeper stop, meaning that it’s useful for… ## [Printing a reel](https://notionparallax.co.uk/2024/reel) _2024-09-10 · Notion Parallax_ I have a thing that happens in my brain, maybe it’s because of a brief time as a person who made things, that I think I can make things. It means that I’m pretty resourceful, but it’s also got me into some serious pickles over the years. I’ve thought about it a lot, and I’m able to catch myself before I get into serious trouble—mostly—but I’ve found an upside to it. By making things myself, I…
