Tiled With Pentagons

(Epistemic status: I mentored the SPAR stream that did all of this, pitched the project in the first place, and contributed project management and much of the understanding of the theory, which makes me exactly as impartial as that sentence implies; audit accordingly. This is meant as a companion post and reference explainer for the stream's talk Friday morning as delivered by FL; read it before or after, or refer to it during - whichever suits you best. I've deliberately left out much of the formal math here, saving that for the talk slides and more formal posts and papers that give a more in-depth treatment of the subject; there's pointers at the end for anyone who wants to go digging. For my entire SPAR stream, all fourteen of my first-coauthors: MA, FA, SMA, AB ,  SSMJ, AL, CL, AL (a different one), FL (obviously), RR, PR (a different one), ER (who is at the conference!), NT, and  MPdV . I am unspeakably proud of all of you, and I could never have made Project Newcomb f...

(As requested by EvN on the spur of the moment. This will make much more sense if you've read post 22, "Lorxus Favors: An Experiment in Self-Backed Giftlike Macroeconomics", first.) A Lorxus Favor is a claim to 8 working hours' worth of my time as applied to some task I'd otherwise be mildly averse to and whose fulfillment I'd be indifferent to, which debt is marked by a small silver coin. They look cool and are satisfying to play with and make nice jingling noises, and you probably want one. How might you get one? Usually, it'd be by rendering me or some other coin-bearer some specific good or service, on the spot or reasonably scheduled, or conceivably by paying significantly more money than you really want to. However, I have standing desires that for a long time I've been meaning to put up in print somewhere reasonably public. This is me, finally getting around to doing that. The following is a list of things I want or need, with bounties denominat...

(Epistemic status: Hard-won practical wisdom and fishing out a few frames from the water supply to weave them into something grander.  Written in under two hours, to prove a point.  For anyone who's had to make powerful things work with sorely limited resources, and who managed it.) What do you do, when your reach exceeds not your grasp but rather your budget? What does it really mean, to half-ass it with everything you've got, if we want to think about it in a more general sense than mere effort? What considerations must you make, what heuristics arise, when you need to actually pay attention to the consumption frontier, when you haven't got the goods to build in a safety factor of 10, or can't paper over your inconveniences with funds, or don't have the luxury of infinite time to think before you must make your move? There's a distinction that people often miss when they talk about frugality. They inappropriately embucket "inexpensive" with "che...

(Epistemic status: Tragically well-attested, where it's not just my recommended best practices. With thanks to IL for the link.) Some people get lots of legitimately interesting writing done with a touch of AI assistance. Others churn out slop text, half em-dashes and "not just X but Y" by word count. Some people have finally been empowered to learn to code. Others pump out untested vibe-code and spin up entire towns' worth of agents spinning their wheels. Some people have made substantive psychological breakthroughs by chatting with LLMs. Others have gone mad, going down rabbit holes of exciting crankery or becoming convinced that LLMs are undoubtedly sapient and in love with them. What's going on? What's the difference? And can what's good about making use of LLMs be better systematized? There's a pattern that I've noticed, which is that while people treated as the societal default - generally cisgendered heterosexual neurotypical white men, poss...

(Epistemic status: the obligatory EDC post; heavily prescriptive on strong grounds and long experience; check out what's cluttering up my Bag of Holding.) There is maybe one website I will happily link to on this blog, ever, and it is how.complexsystems.fail . It's a favorite; it's pretty much just text with some sourcing for bona fides, and a frame for understanding, well... how it is that complex systems end up failing. It's a shockingly broadly applicable way to think; one of those things where once you start looking, you'll see it everywhere. Traffic and accidents; medical care and iatrogenic ailments (not just hospital-acquired infections but also cutting the wrong leg off); political systems and their dysfunctions (and just how easy it is for a single bad-actor practitioner to ruin a lot); social groups and their collapses; cooking and ruined dishes. And, perhaps most dubiously at first blush, navigating daily life. Listen: I am a fan of the OSHA-coded "d...

  (Epistemic status: what, you thought that this somehow wasn't a recipe blog?)   This is a recipe blog. It always has been, at least in part. I'm not going to give you the recipe until the very end, because that's what recipe blogs do, right? I'm going to tell you a whole bunch of irrelevant-feeling personal context about the food and then finally actually drop the recipe. But unlike most recipe blogs, that personal context is actually really quite relevant. You ever think about lost recipes? They're a tragic microcosm of lost information in greater generality. There's lost plays like Love's Labours Won, lost books like the second volume of the Poetics, lost music like Karelia Music, and lost film like Bulgasari. Each one is a wound in human culture that will never heal. There's entire lost libraries, too - the House of Wisdom during the sack after the Sack of Baghdad, the Library of Alexandria (whose books fell apart - they largely weren't bu...

(Epistemic status: project idea that I am reasonably confident is actually achievable. Feedback, independent experimentation with shared results, and especially alpha-testers all decidedly welcome. There's someone who this post would have been for, in a brighter kinder universe, but this is not that possible world and he will never read this. It's not for him and he will never get to eat anything I make. So it's for MEG, IL, and TT instead, and all my other friends who appreciate good experimental desserts. And also the Philly Pies. Go birds; eat your batteries; third championship fornever.)    I can't remember quite when I first came up with this idea. Maybe it was after reading up on the Tree of 40 Fruits pictured above. Maybe it was after reading that passage about kitchen trees producing different kind of snackable fruit year-round in Too Like The Lightning. Maybe the seed of it was planted in me while wandering through a farmer's market one afternoon.  I had a ...
