Choux pastry (the kind used in eclairs and creampuffs) is very picky, and depends heavily on the chemical properties of eggs. Five years ago I played around with trying to make it eggless with aquafaba and xanthan gum. It didn't work, but now that we have vegan egg white protein, can we do this for real?

Nope. I gave it several tries over vacation, and wasn't able to get it to puff properly. Here's the closest I got:

I keep my recipies on my website, and like most of my website it grew over time instead of being designed. A couple years ago I added some progressive enhancement that puts checkboxes on the ingredients, and today I added a rescaler:

Our family is on vacation in North Carolina for a week, spending some time at a pool, and they're playing a (weirdly short) loop of music. Listening to She's In Love With The Boy for the fourth time I was thinking about how it's an example of a common pattern in country music: a repeating motif, recolored by the verses. In this case it's a father saying a boy isn't good enough for his daughter (verses 1 and 2) until his wife reminds him that her own father said the same thing about him (verse 3).

Some others with variations on this pattern:

I've been thinking more about disaster preparedness recently, and an important piece of that is food. And for many foods, before you can eat them you need to cook them. For example, a large fraction of the calories in our house are dry rice and pasta. These have ungelatinized starch, where the nutrition is bound up very tightly in starch granules. We mostly can't digest these as-is, but heat and water gelatinize the starch and make it bioavailable. [1]

This means you need some way to heat things up. If the power grid is working then you have lots of options, including immersion heaters and boiling water with a kettle, but in many disasters this is not an option. What else can you do?

A contra dance organizer in another city wrote to me a while ago because they were stuck: the dance was in a few days and they didn't have anyone to run sound. They were asking if they could use some of my recorded music for the dance. Here's a lightly edited and linkified copy of what I sent them:

This is a tricky situation, and I'm sorry you've ended up here. This is probably not what you want to hear, but I would not hold a dance with recorded music. Instead I'd:

Daniel Drucker pointed me at a fun bug in Google's calculator: the parsec is wrong when you do math on it.

As the earth travels around the sun, closer stars appear to shift back and forth against the distant background stars. The closer the star is the bigger this effect is. Think of how when you switch which eye you're looking through you notice near things shifting relative to farther ones. For example, holding up my finger I see this out of my right eye:
