somewhat contrary to the previous post: another pet peeve is people (some classic libertarians, others paleoconservatives) saying that "there is no free lunch".

there are certainly zero-sum, no-win situations that occur in life sometimes. and the phrase is often also used in some fatalistic, eschatological, broad heat-death-of-the-universe sense. sure sure, second law.

but as the great MC hawking put it: the earth's not a closed system, it's powered by the sun. there's an effectively unlimited massive fusion reactor in space we literally all live off of, and for all practical purposes we always have and always will. it is very much a free lunch! concretely: every lunch you have ever eaten and will ever eat is a free lunch given to earth by the sun.

also like .. any technological improvement that increases efficiency of some work is a metaphorical free lunch. if there were no free lunches to be had from R&D we may as well be banging rocks together as using any later developments.

also any positive-sum games or interactions, social relationships, political organization, economic cooperation .. the list of free lunches goes on and on.

enjoy your free lunches!

flywheels, again

reading some technology reporting today and they're using the term flywheel, a pet peeve of mine. I have written about this before on some ephemeral social media, but I am moved now to repeat my objection in a place of greater posterity.

the word "flywheel" seems to have entered the business-writing lexicon with a book about amazon called "good to great". I have not read this and have no intention of reading it. perhaps the metaphor was used sensibly there. it is no longer used sensibly. here are a couple representative samples I just found via google of the way it is used nowadays (emphasis mine):

By definition, a flywheel is a heavy revolving wheel that is used in a machine to increase momentum and therefore provide greater stability to the machine. Given its weight, the flywheel is difficult to push from a standstill, but once it starts moving it gradually builds momentum, which eventually enables the wheel to turn by itself and create even more of its own momentum through a self-reinforcing loop.

or:

A flywheel is a massive metal disk, or wheel, that often weighs over 2,000 kgs. It takes a lot of effort to get it started, but once it starts to turn there are counterweights around the outside of the wheel that start to take effect and it starts to build momentum almost by itself. From that point, the same effort can be placed on the flywheel and it will start to turn faster and faster.

this is characteristic of the way people use the term now. they talk about "getting the flywheel going" on their business, because once you're over some kind of threshold the flywheel will somehow magically start spinning faster and faster on its own.

that is not what a flywheel is or what it does at all.

a flywheel is a kinetic battery. you put angular momentum into it when you have a surplus and you can take some back out when you have a deficit (assuming friction hasn't lost it all yet). other metaphors that have a similar effect are account balances, or warehouse inventory, or queues. or taking an average of something noisy over time. take your pick.

a wheel that somehow went faster of its own volition would be a perpetual motion machine. a fantastical solution to all the world's energy needs. but also fairly prohibited by .. physics. there is no such thing.

people using the metaphor this way seem to be getting it confused with positive feedback phenomena. which do exist! even in business! here is a classic one: sales volume up => unit production cost down => sale price down => customer demand up => sales volume further up. a.k.a. "economies of scale". great stuff, bravo capitalism. it has some other positive feedback loops that are not so great like "overproduction crisis" or "market panic" but we need not dwell on those.

there are also lots of other non-capitalism examples of positive feedback phenomena. population growth, cytokine storms, even the digital flip-flop circuits storing this post are positive feedback systems.

but: a flywheel is not a positive feedback system. not at all. please, I beg you: for pity sake stop using it as a muddled metaphor for one.

I just noticed this post from around when I first learned the term "substructural type system" is (almost) 20 years old. That sure was a while ago.

(I knew the space of ideas already but was working my way through more legit treatments of it. amusingly none of the research links in that post are live anymore -- back then arxiv.org was still "xxx.lanl.gov" haha)

The paperwork for my credential has FINALLY gone through, so I am actually done with BCIT. Unless I need to get a transcript or something, I guess. \o/

Meanwhile, have some links. Roughly zero percent of these are cheerful.

The culture war is a metaphorical war (for now), but the metaphor is valid makes two points, neither in as much detail as I would like.

One: "We liberals really need to acknowledge that (a) we are in a culture war and (b) we are the aggressors. Racism, sexism, and homophobia have been features of the dominant culture since... well, pretty much forever. We are engaged in a conscious effort to marginalize -- and, if possible, extirpate -- these tendencies, and we are using whatever means we have at our disposal to do so, including the sword of the state."

Two: "...[A] very deep cultural and psychological problem on the liberal-left, which is a pervasive tendency toward various types of Whig history, in which history itself is more or less assumed to move in an inevitable direction, with a sort of vaguely Marxisant or quasi-Christian eschatological faith that in the end the good guys have to win because that’s the ultimate plot line."

I do not, in fact believe that 'the moral arc of the universe ... bends towards justice,' because why would it? Any bending has to be done by us, by people who act to bend it, and in the face of thousands of years of tradition, fear, and resource-insecurity.

San Francisco in the middle sixties was a very special time and place to be a part of. ... There was a fantastic universal sense that whatever we were doing was right, that we were winning. And that, I think, was the handle - that sense of inevitable victory over the forces of Old and Evil. Not in any mean or military sense; we didn't need that. Our energy would simply prevail. There was no point in fighting -- on our side or theirs. We had all the momentum; we were riding the crest of a high and beautiful wave. So now, less than five years later, you can go up on a steep hill in Las Vegas and look West, and with the right kind of eyes you can almost see the high-water mark -- the place where the wave finally broke and rolled back.
--Hunter S Thompson, "Fear and Loathing in Las Vegas"

Related, I Want No One Else To Succeed: "I've been doing this experiment on classes for the past 10 years and not one class has agreed unanimously because there’s always somebody who doesn’t want someone to have what they have because they don’t think they deserve it."

Also related, [personal profile] rachelmanija reviews Dying Of Whiteness: "[W]hite people perceive their own interest as upholding white supremacy and punishing people of color and liberals. They value this so highly that they are willing to deprive themselves of money, material goods, and even their own lives in pursuit of this goal. And they are doing exactly that: literally killing themselves as a side effect of killing people of color, in a kind of cultural murder-suicide." Erik at LG&M reviewed it some years back as well. His concluding words feel prescient. "Until whites stop preferring to kill themselves rather than admit non-whites as full citizens of the nation, fascism will continue to be a serious threat to the rest of us. And to themselves too, but they will be A-OK with that."

Who Goes MAGA?, a fictitious analysis of various personalities. "It attracts those who mistake confidence for competence, who confuse being loud with being right, who think that admitting uncertainty is weakness." (Also links to Dorothy Thompson's 1941 essay "Who Goes Nazi?", also worth a read.)

And, in case the previous weren't depressing enough: Assuming the can opener of free fair elections and a subsequent Democratic victory in 2026 and 2028: "Will America’s non-fascist party have the will to purge the government of fascists?" In which the FBI is conducting witch-hunts against employees who were friendly with people on the director and deputy director's 'enemies lists'. Primarily concerned with There Will Be No De-Trumpification:
Imagine it is 2028 and Democrat X has won the presidency. Kash Patel will only be four years into his term as FBI director. Dan Bongino is now a career employee of the bureau. The entire agency will be stacked, top to bottom, with Trump loyalists.

Would a Democratic administration have the will to purge these Trumpist elements from federal law enforcement?

I’m pretty sure I know the answer. And you’re not going to like it.

There will be no housecleaning of any Federal agencies; Trump appointees will remain in place despite their commitment to opposing Democratic governance and priorities. There will be no significant rollback of ICE's increased budget and powers.

We have the model for this: Obama in 2008 declining to go after the banks; Biden's appointment of Merrick Garland to fail to investigate the 6 January coup attempt. Hell, the pardon and rehabilitation of Richard Nixon.

Well. Two hundred fifty years was a good run, I guess.

I decided to be a bit lazy with July’s stationary choices, so we’re continuing 2 pens from last month and just adding in the pen that I had been using for todo lists, and repeating the bunny sticker sheet that I hadn’t finished. I did get some new puppy stickers for my calendar (I’m currently tracking which days I spend some time writing). It’s a bit of chaos here this month as I finish my job, work on writing for a little fanfic event I decided to join, and then do some travel to visit family, so I don’t think I’ll be doing much actual journal writing.





Pens, Ink and stickers for July 2025.  They're described in more detail in the post.




Inks & Fountain Pens:






  • Pilot Metropolitan <CM> with KWZ Gummiberry




  • Pilot E95S <M> with Pilot Iroshizuku kon-peki




  • Ooly duo with original pink cartridge and orange highlighter





Stickers:






  • Meowashi bubble tea dogs




  • Stickii books and bunnies




  • Mind Wave puppies




  • The Latest Kate elephants





No changes to paper this month either!





Notes from last month:






  • I picked up an Endless Phantom retractable fountain pen during their kickstarter and it arrived. Unfortunately it seems to dry out constantly, so I’m going to try reseating the gasket (they have a video on how to do this) and we’ll see if I have better luck after that. I spent a bit extra to get a fude nib and it writes beautifully when it writes, but it’s been pretty frustrating!

In Minneapolis, where it is overly Warm but where there were decent fireworks and a lightning-filled thunderhead last night. Feeling some kind of way about the political situation, for sure.

Have some links.

UPDATE! Breaking News: Everything Is Bad. (This is absolutely worth your two and a half minutes, I promise.)

Edward Gorey’s "Great Simple Theory About Art" is essential reading for writers: "[T]he theory ... that anything that is art ... is presumably about some certain thing, but is really always about something else, and it’s no good having one without the other, because if you just have the something it is boring and if you just have the something else it's irritating." That last bit puts me in mind of James Nicoll's "I don't object to hidden depths but I insist that there be a surface."

ICEBlock: "ICEBlock is an innovative, completely anonymous crowdsourced platform that allows users to report Immigration and Customs Enforcement (ICE) activity with just two taps on their phone." US only, and iOS only at the moment. Via jwz, who notes "The cowards at Time wrote a whole article about the app and didn't include a link to it".

methaphone: "methaphone can help you manage cravings and withdrawal symptoms. It can fill that hole in your back pocket. ... methaphone looks like a simple acrylic slab -- and it is." I kinda want one. (I am a sucker for glass and lucite.)

We're having to rebuild the search server again (previously, previously). It will take a few days to reindex all the content.

Meanwhile search services should be running, but probably returning no results or incomplete results for most queries.
