Winter wonderland in Wisc-a-nsin

It looks like I will likely start being a lot more active on here.

Hi guys!

Talking to former Twitter trust & safety folks... and they note that *normally* under existing policy, accounts are supposed to get strikes for violating policy, not be immediately permabanned.

Remember how Elon said no content moderation policies have changed?

Well, I'd say... that's changed.

The Koide formula is a mysterious relation between the 3 charged leptons:

the electron,

the muon (like an electron but ~206.768 times heavier),

the tau (like an electron but ~3477 times heavier).

Nobody knows whether it's really true or just a coincidence.

For the most part, serious physicists have given up seeking relations between masses of elementary particles, because it's so hard to *explain* any such relations.

Hello Mastodon!

the growth of AI mostly makes me despondent. i like systems that are constructive, built from understandable parts, repairable, possibly provably having some property or other, freedom-enabling, using universally available hardware -- all things that "AI" isn't. but it appears to be an essential part of life in the next decades

Well this is interesting. Compare the images below. Two years ago, Northwestern canceled an event with a gay musician at its campus in Qatar. Its partner the Qatar Foundation said it was canceled for offending Qatari values. Northwestern denied this. Now a former dean says the Qatar Foundation ordered the shut down. It sure looks like Northwestern isn't being honest about free speech on its Qatar campus.

Need the area of a broken polygon?

Don't bother fixing it.

Just sum up the cross product of the two endpoints, and divide by two.

[Here u × v := u₁v₂ − u₂v₁. Works even if the polygon is nonconvex. Caveat: all segments must point counter-clockwise, since u × v = −v × u!]

My favorite memory of Jason Calcanis was when PVRblog was happily chugging along, it made me several grand a month in revenue as my spot to talk about TV and streaming. Then Weblogs inc started PVRwire and after a couple months he reached out to inquire about acquiring PVRblog and when I asked for a number, the number was zero, but I’d get paid some percentage of ad revenue from my work.

So: hand over the domain, my content, and all control instead of keeping 100% of my own site’s revenue.

Can't get this shot of Gritty in a Philly airport mural out of my mind. He is feeling FINE.

hello all! i don't know how to use this site yet or if we're allowed to be funny on here!!!! this is the real me (apparently there is an impostor account with my old profile pic and my bio which is alarming). you can tell i'm the real me because i will now share a secret that only you and i know: possible worlds are real

Is this thing on?
I joined twitter 9 years ago, skeptical of what I would find. But it turned out to be incredibly valuable for me. I'm sad to see what has come of it, and not very hopeful. I'm glad there is an alternative. I like a lot of the ideas behind mastodon, but I'm also a bit skeptical in a different way. But I'll give it a shot. Hopefully, I'll be pleasantly surprised again.

i liked the site better when i could toot
