Today I had a successful POTA activation, logging zero QSOs.
How did I do that?
As a control operator of a club station, I supervised two new hams with Technician privileges making successful SSB QSOs on 20m, giving them a taste of what they'll be able to do on their own, once they get their General (or Amateur Extra) upgrades as each of them plans to do.
Also, I helped one of them work on CW.
I'll get my own 10 again another time.

I gave the Strangers in a Tangled Wilderness crew the significant challenge of trying to make me sound coherent in this interview with Inmn Neruin. I was managing some pretty significant sleep deprivation and a mild cold, but I think it turned out pretty good (despite my best efforts).
But I did talk a lot about my trauma related to some of my experience living in #rural areas, and in doing that I was definitely not as careful as I could have been to talk about that as a trauma experience rather than as reality. Some people get trapped in rural areas, but other folks live there because they find beautiful things.
Not only is #RuralOrganizing critical (Trumpism grew out of areas neglected by "the left"), but rural living can be beautiful and rewarding. I briefly mentioned growing up throwing knives. A friend of mine lived way out in the woods, and there's something special about having a playground that spans several square miles. Intertwined with the old settler colonialism, antisemitism, *phobias, and isolation, that is at the heart of a lot of my personal rural misery, there's also a joyous and feral thing that taught me a lot and, I think, helped me organize more fearlessly. That thing is both individualist and collectivist, in different ways, and I don't think it's well understood without experiencing it. There's far more nuance than I was able to offer (and I definitely could have been more careful not to play into anti-rural stereotypes).
I think I said, "no one wants to live there." People do. You do. So let me try to fix that by giving you a chance to talk about that. I also talked about how slow things move, how nothing changes, but there are also sometimes opportunities to change things in huge ways specifically because structures don't exist to stop those changes. So while I'm bumping this zine and interview, also I want to use this as an opportunity to welcome my rural comrades to help fill in the gaps:
What draws you to where you are?
Do you choose to live in a rural area vs urban, and why?
Is there any other thing I've said that you would like to correct?
What other things should folks know?

Giving some more thought to replacing my 2007 Mazda 3 with a used EV. The two-door electric Minis seem like a good fit in terms of size, range, and style. I also like the Fiat 500e, but it seems a little too small. What else is good?

Improved Approximation Guarantees for Groupwise Maximin Share Fairness

Abstract: We study the problem of fairly allocating a set of indivisible goods to a set of $n$ agents with additive valuation functions. We focus on the very demanding notion of \textit{groupwise maximin share fairness} (GMMS), which requires that each agent $i$ receives value comparable to their maximin share, where the latter is computed \textit{with respect to any subset of agents that contains $i$}. We show that it is possible to compute $(\phi-1)$-approximate GMMS allocations in polynomial time, where $\phi \approx 1.618$ is the golden ratio). This improves on the previously known guarantee of $4/7$ of Chaudhury et al. [SICOMP; 2021] and Amanatidis et al. [TCS; 2020]. We propose a simple algorithm that maintains the same main properties as the Draft-and-Eliminate algorithm of Amanatidis et al. [TCS, 2020] and we improve on the approximation guarantee analysis by carefully bounding the relevant value within any subinstance induced by the restriction of our allocation to a subset of agents. Our analysis is asymptotically tight for algorithms that share these properties and has the additional benefit of giving improved guarantees for restricted settings; in particular, when the agents agree on the top $n$ goods or when the number of agents is small. To illustrate the challenges of going beyond the guarantees of our algorithm, we also present a variant with an improved approximation of $(\sqrt{10}-1)/3 \approx 0.72$ for the case of three agents. To achieve this improvement we partially characterize the maximin share guarantees of short picking sequences for a small number of goods.

Worth looking at both the quoted text here and •especially• the linked page, which is quite good.
I’ll add another item of my own. The first screenshot mentions giving an LLM the task of “implementing an HTTP server in JavaScript from scratch” in 90 minutes. Sounds impressive, right? Until you remember that every open-source Javascript HTTP server in existence ••was in the training data••.
