After some more programming and debugging and printing, I now have version 2 of the folded-bore shakuhachi. To my surprise, this one is already a useful musical instrument with a clear, easy tone. It's a strong indication that this is a useful path and I'm so happy about it! Guitar pick for scale... this is small.

Voting is harm reduction. Even if you think taking heroin is bad, you can still support health treatment for addicts.

I present to you the world's first folded bore shakuhachi.

If you need to keep maskless assholes from getting too close to you in public, it turns out that bartitsu and la canne de combat have a lot more practical use than I imagined when I was studying them.

Not to let peaceful reform get out of hand or anything, but now that more people can see the structural incentive mismatches that prevent the police from being agents of true justice, it's worth noting: pretty much the same things apply to elected officials and their appointees.

I recently realized that English has a double genitive form after thinking about the question of whether to include the apostrophe s in a sentence like:

[*?] I want to speak to a friend of John.

I want to speak to a friend of John's.


Sourdough crepe, made with cheese and curry in the batter, served with apricot jam.

Since so many people have not asked, I have brought the "is Trump in prison yet" bot here.

I have a joke about BDSM but first I need your enthusiastic consent.

There are refinements to be made before it is a real professional-quality instrument, but I feel like the approach has been validated and I now have little doubt that it's an achievable goal. For the most part this one plays in tune and with excellent tone, which the crappy webcam mic doesn't really let you hear. But so exciting....

Literally as soon as I started playing shakuhachi ~20 years ago I started thinking about 3d printing them, but hadn't taken any real steps in that direction until recently. David Brown, who makes the finest shakuhachi I have ever played, has been kind enough to share his expertise, measurements, and techniques with me, and a couple months ago I started working on a set of programmatically-modeled shakuhachi. My 3d printer is still in shipping limbo, but due to a friend's generosity I have one!

How should we deal with people who are as mean and horrible as Mark and Patricia McCloskey? I can think of a lot of fun, possibly legal, revenge pranks to reward them for being such horrible humans.

Maybe I should start a foundation focused on (legal) pranks against horrible people. That actually sounds like fun. Talk me into it?

I am ready to dispense opinions for public consumption in response to responses made to this post.

I just realized something really scary.

The way that fb and the horrible birdsite display their news feeds: an infinite scrolling list in rough order of what they think will cause you to react... is based on my early work with (and arguably invention of) collaborative filtering in the early 90s. It was a good idea, but in widespread adoption has seemed to cause some terrible, real problems.

I'm really sorry, everybody.
