The barball strategy, popularized by Nassim Taleb, is a way to navigate risk/reward tradeoffs when you’re skeptical about the accuracy the risk estimates. While it originated in financial investing, it can apply to product and business strategy. Imagine a menu of investments ranging from low-risk & low-reward to high-risk & high reward. The barbell strategy picks mostly conservative low risk investments to cap losses, and a few high risk bets …

A common mistake I see in web components is this: class MyComponent extends HTMLElement { constructor() { super() setupLogic() } disconnectedCallback() { teardownLogic() } } This setupLogic() can be just about anything – subscribing to a store, setting up event listeners, etc. The teardownLogic() is designed to undo those things – unsubscribe from a store, remove event listeners, etc. The problem is that constructor is called once, when the component …

To escape the neutral, I had long since forsaken the being for the persona, for the human mask. When I humanized myself, I’d freed myself from the desert. I’d freed myself from the desert, yes, but had also lost it! and also lost the forests, and lost the air, and lost the embryo inside me. The mask—humanisation—that we put on to help us elude the harshness of reality. A personal …

2023 has come and gone. Compared to the several preceding, it was a year pleasantly free of drama for me. I photographed opportunistically close to home for much of it, with three more substantial outings. I was very happy to have a great if short photo backpack in the big scenery of the Salmon River canyon, a longstanding wish fulfilled. Making the acquaintance of the true North Cascades was great …

I’ve been thinking alot about civic participation in machine learning systems development. In particular, involving non-experts in the potentially value-laden translation work from specifications that engineers do when they build their models. Below is a summary of a selection of literature I found on the topic, which may serve as a jumping-off point for future research. Abstract The literature on participatory artificial intelligence (AI) reveals a complex landscape marked by …

Thursday, January 11, 2024 a concise theory of notes about notes Previously: notes on notes 2020: meta meta 2020: the zettelkasten / the zeitgeist I came across an argument about what exactly makes something a zettelkasten, and then thought: “Zettelkasten” is a pretty great example of how one of the best ways to fuck up a neat idea is to have a bunch of people get really excited about it. …

This nebula is very, very dim and therefore it's not very popular with astrophotographers as it takes a long time to get a decent image. All in all this image took me over 50h of total exposure time over multiple weeks.The nebula itself is quite similar to many other nebulas with a center that glows from oxygen and sulphur emissions embedded in a larger area of hydrogen gas. There's also …

To understand how far the modern Republican Party has fallen, please read this famous speech by President Dwight Eisenhower. Ike’s thoughtful reflection is a breathtaking contrast with the bombastic idiocy of the most recent Republican to live in the White House. (Eisenhower would likely take Joe Biden to task, too, for the current president’s strike in the Middle East, and for the escalation of violence in a region already suffering …

Happy new year everyone! It’s been fairly quiet on here and there’s a second instalment on the AudioMoth deployment at Lady Bay Reef which is currently in the works. This has taken much longer than expected to pull together, largely owing to going out too deep (pardon the pun) and having to rein myself in again. Between this heave-ho, I’ve been creating some new videos which provide an overview of …

Speaking of extremely helpful error messages, recently this error greeted me upon retrieving my phone from my running belt after finishing a run. I guess it’s a… non-modal modal? It doesn’t allow you to do anything until dismissing it, but it also doesn’t stop anything – notably, it skips the broken track within a millisecond and just continues playback. It happens so quickly that even when actively observing you have …

The amount of content on the web is so large, that it's tricky to find the stuff worth reading. One of my strategies is to follow people I trust and read what they share. For anyone with interests similar to mine, I've opened a Links section on this website, too (with it's own RSS feed). My plan is to publish no more than a couple of links per day (if …

The Inconvenient Mind paper on the climate mind and the polycrisis, argues that in times of growing uncertainty, fear and anger we need to move away from facts and seriously start listening and engaging with emotions Source Related posts: Communicating the Future, Guv How to Get a Job in PR Free Ebook: How to Become a Freelance Consultant Moss Graffiti Privacy

$\newcommand\F{\mathbb{F}}\newcommand\R{\mathbb{R}}\newcommand\C{\mathbb{C}}\newcommand\Z{\mathbb{Z}}\newcommand\tr{\operatorname{trace}}\newcommand\End{\operatorname{End}}$ The trace of a sqaure matrix $A$ is defined to be the sum of the elements along the diagonal. A basic fact is that for any invertible matrix $M$, \begin{equation}\tag{*} \tr(M^{-1}AM) = \tr(A). \end{equation} Let $V$ be an $n$-dimensional vector space over a field $\F$. The trace of a linear transformation $L: V \rightarrow V$ is usually defined as follows: Let $(v_1, \dots, v_n)$ be a basis of $V$. …

So you’ve got a log. Maybe its a tree that came down nearby, or maybe somebody heard you’re a woodworker and offered you a log. And you have a bandsaw. You start wondering if you can mill this log into boards yourself. Sure, you could invest in an Alaskan chainsaw mill, or you could try to find someone nearby who runs a hobby sawmill to cut it up for you. …
