Before I hear your jibber jabber on politics, I need you to recognize this is the median voter:

`git clean -d -f -x .` seems to have worked, seems like I had a bunch of old stuff cached that wasn't getting rebuilt after a `git pull`
thanks for the help!

A Farcaster post from amadon.eth Worldcoin opened a LA location and somehow thought it was a good idea to have me speak. Spent 25 min calling out proof-of-person as a spoofable scam, warning about the surveillance state they’re helping to build, and telling everyone why they should never give up their biometric data. The looks on the Worldcoin staffers’ faces were priceless.

Can any ATProto gurus give the lowdown on why I need to enter my password on a different domain from my PDS? For ex, here's deer.social's login page. Why is OAuth not a thing here? It breaks password managers (read: phishing waiting to happen)

True, but that's just self declared in the token contract, there's no official naming system like ENS for tickers. Tickers can change between exchanges. For example, I followed Status which had $SNT, but some random AI trading bot started trying to ursurp the $SNT tag on X. But CG choses one:

Ser, per the FAQ
A screenshot from ecashact.us that says: "Importantly, E-Cash is not: 1. A CBDC (Central Bank Digital Currency). Although E-Cash is a form of digital dollar, it is issued by the Treasury, not the Federal Reserve, and accordingly is not a CBDC. 2. In competition with a CBDC. E-Cash is intended to complement and be developed in parallel to other forms of digital public finance, including CBDCs, FedAccounts, Postal Banking, and Public Banking."

I'm a big fan of the new tipping meta on Farcaster. Reward people for the value they bring into your feed. Zero crypto required (it's all stablecoins).

And it actually works! (unlike the lightning network)

Not to bury the lede, but we don't even know who the insurance company is, shouldn't they get credit for taking the risk of approval with this experimental treatment?
Screenshot that says: His pain never let up. One day he said to Deborah, “Mommy, I’m in pain every single day.” Kendric wants to be like other kids, but fear of pain crises has held him back. He became increasingly sedentary, spending his days on his iPad, watching anime or building elaborate Lego structures. Despite his many absences, Kendric kept up in school, maintaining an A average. Deborah and Keith began to hope for gene therapy. But when they found out what it would cost, they lost some of their hope. But their insurer approved the treatment in a few weeks, they said. Now it has begun.

Privacy is normal.
A poster from ZCash that says: Privacy is normal. Privacy is for good guys. It's for moms and bike messengers and foodies. Privacy is for business meetings and voting booths. It's why we have shower curtains It's why we have that little padlock icon in our browser bar. Privacy protects you from discrimination and from identity theft, and it keeps your food-delivery history under wraps. It can also shield you from those creepy somebody-has-definitely-been-listening-to-my-thoughts ads on social media apps. Privacy isn't about shutting out everyone and everything, Instead, privacy gives you the power to choose what and with whom you'll share. It provides safety, control and the right to grant access Privacy gives you the ability to express yourself, to be creative, to spend your time and your money in whatever manner you like, without the scrutiny of others. It protects our intimate moments, our most embarrassing ambitions, our radical ideas and the ability to be our true selves. Privacy is freedom, consent, dignity and security. Privacy is normal.
