Very few people have been on a plane performing a barrel roll, but we could fix this. Commercial aircraft could roll in revenue service, and if you had your window shade down you wouldn't even notice it.

While there are many ways to roll an airplane that would cause complete havoc inside the cabin, a barrel roll can be performed as a "1g" maneuver. With careful control of the aircraft, the forces can be balanced so that you only ever feel close to 1g of apparent gravity, and it always is pulling you down into your seat.

It's a holiday. The cousins are over, and the kids are having a great time. Unfortunately, that includes rampaging through the kitchen. We're trying to cook, so there's a "no cutting through the kitchen" rule. Imagine enforcement looks like:

Kid: [dashes into kitchen, pursued by cousin]
Adult: Out of the kitchen!
Kid: Sorry! [Continues their path, leaving through the other door; escapes pursuit from more rule-abiding cousin]

This doesn't work! The kid got what they wanted out of this interaction, and isn't going to change their behavior. Instead, I need to make it be not worth their while:

The "dance weekend" is a very common pattern for contra dance communities around the country. I think of the central example as something like:

• Two bands, two callers.
• Dancing (with short breaks) Friday 7pm-11pm, Saturday 10am-11pm, Sunday 10am-3pm.
• Saturday and Sunday daytime are a mixture of regular dances and workshops, sometimes with parallel tracks.

Examples, from my 2025 calendar: Beantown Stomp, Chehalis, Dance in the Desert, Dancing Fish, Five Borough Fling, Fleur de Lis Fling, Hashdance, and Summer Soiree.

I've seen a bunch of misunderstandings that come from people not being on the same page about what is normal: many dance weekends are organized by volunteers, some of which are doing it for the first time; performers often are new to this as well. As someone who has both played for and organized dance weekends, I thought it might be helpful to try and write down what I think of as typical if an event is bringing in a band or caller from out of town.

Note that I'm trying to document the status quo here, saying "this is" and not "this is what should be". I would be sad if in places where the status quo isn't great people pointed at this doc and said "Jeff says it's supposed to be that way"; this post is not doing that! Additionally, performers and events are of course free to agree on something that isn't the most common arrangement!

As of the beginning of 2026, here's what I think of as the most common arrangement:

I play for contra dances, and a core part of our culture is that we always have live music. It's not that live music is categorically better: if you ran a test where you put soundproof one-way glass in front of the musicians and secretly played a live recording from a great band playing for the same dance it would probably go really well. Instead, we insist on live music because that's the kind of culture we're trying to build, one where the performers are part of the community, where anyone can start playing for dancing, and where the music grows and changes with the culture.

Other groups went different ways. The late 1940s explosion in square dancing happened in part because of technological progress: it was now practical to record a band once and play it back millions of times to support dancing all over the country. Callers would buy a sound system, including a record player, and all they needed was some dancers and a hall. This let modern square dancing grow enormously.

Contra dance took a different path, coming through the 70s folk revival with a strong commitment to live music. Musicians were drawn to the dance form, and dancers learned to play. With regular opportunities to perform, they learned to adapt playing to support the dancing. As the choreography and musical sensibilities changed over the years, the live tradition could change with it. I love what bands are doing now, and if you compare hall recordings to decades ago it's impressive how much the genre has matured and flourished.

Our family has half a Honda Fit, and it's great! Reliable, pretty good mileage, holds our family of five plus a vacation's worth of luggage, seats fold flat for when I'm bringing sound equipment to dances. It would be nice, though, to be able to seat more than five people.

None of the options are very good: you pay a lot for a sixth seat, not just in price but in size and fuel economy. What I've wanted for years, though, is a six door car: the same height and width as a hatchback, with three rows of seats. All three rows would go in front of the rear axle, unlike a station wagon, so you have plenty of room for luggage and no one is sitting in the crumple zone. And you could fold both sets of rear seats flat, to get a really great cargo area when you needed that.

I had a very hard time getting LLMs to draw what I had in mind (they're stubbornly convinced, like most people, that cars do not have six doors) but I did eventually get Gemini to draw me a Fit Stretch:

I hear people talking about "skyrocketing" rents, with the idea that rent is going up quickly. This isn't my impression of what's happening, and when I look at the data it's not what I see either. Instead, rents are too high, and they were rising quickly pre-covid, but recently they've been stable in real terms.

Here's the data I know best, the price of a 2br that I calculate on my Boston Rent Map:
