Excited to share some upcoming live performances. First up, I will be performing a solo set at Wonder Valley Experimental again this year. It's a tiny festival of adventurous music in the desert just north of Joshua Tree National Park, and it's always a fun time 😺🎹🏜️

I’m working on an AI policy for my org that allows us to opt out of AI note taking and prohibits AI in our comms/storytelling. here is my list of reasons for the policy, but my board is asking me to cite sources. Can you help me with any good references you would cite for any of these? (Or an edit or restatement where I’ve gotten it wrong or inaccurate?)

*if you want to argue about why I shouldn’t have this policy kindly crawl into a hole in the ground and cover yourself with soil

I wouldn’t say I’m a good guitarist, but playing guitar does make me feel good.

My wildly overpriced, overcomplicated, upselling, triple-billing, nonfunctional and newly AI-ridden web hosting package just expired. I bought another month to restore my email access, but I need to switch to something else.

I have a few domain names, and a pretty simple Wordpress site, with no actual dynamic content. It could just as well be static html, but with a future blog.

Priorities: cheap, stable, simple, reliable, fast, I guess now preferably not U.S. based.

Any recommendations?

If you are ever near or in NY City you must visit the National Museum of Mathematics MoMath. I can’t wait to go there. Great for kids too!

NO KINGS North Kingstown · Mobilize

When leaders sidestep the courts, undermine due process, tear families apart, and put the wealthy ahead of working people, it’s time to say: enough. History shows real change doesn’t come from intimidation — it comes from people standing together with courage. And in North Kingstown, when we unite, our voices are stronger than any one person in power. No Thrones. No Crowns. No Kings. Bring your family. Invite your neighbors. Let’s fill this space with courage, kindness, and unity. Please keep this in mind when making your signs. Volunteers needed. Please sign up here if you are interested bit.ly/NK3inNKVolunteer TANK is supporting the Big Table Rhode Island initiative at this event. Please bring a non-perishable food item to donate to the NK Food Pantry if you are able. **We have the power and are claiming it together. No Thrones. No Crowns. No Kings.** What began in 2025 as a single day of defiance has become a sustained national resistance to tyranny, spreading from small towns to city centers and across every community determined to defend democracy. Our peaceful movement is bigger than ever. When our families are under attack and costs are pushing people to the brink, silence is not an option. We will defend ourselves and our communities against this administration’s unjust and cruel acts of violence. On March 28th, rise up, take to the streets, and say it loud: no thrones, no crowns, no kings. We’re not watching history happen—we’re making it. Join us. *A core principle behind all No Kings events is a commitment to nonviolent action. We expect all participants to seek to de-escalate any potential confrontation with those who disagree with our values and to act lawfully at these events. Weapons of any kind, including those legally permitted, should not be brought to events.*

So looking for information on heat pump experience in the Eastern Ontario climate.

Anyone have anything to share with someone thinking about a switch? We're on an outdoor wood burning furnace right now.

I love rice and beans, okay?
