This in essence is what @simonw dubbed as the lethal trifecta: an agent with access to internal data, untrusted content and external communication Muse is a great product (and so are the different claw flavors), but how to put the right guardrails in place i guess remains tbd
And once a Mac is exploited, you can interact with any of the users "connected" devices also running Muse. ...meaning you remotely task their mobile (iOS) Muse client ...invisibly 📲🔓👀 What can you do? Welll, some very neat iOS stuff!

OK — Kelpdao hacker, how much you want? Let’s just talk. With KelpDAO’s help, of course. It’s simply not worth it to sacrifice both Aave and KelpDAO and let them go down over this hack. You can’t spend $300 million anyway.

One of the most significant moments from the Trump Davos speech was when he said the quiet part out loud You cannot lower housing costs for young people without destroying millions in wealth for boomers "Every time you make it more affordable for somebody to own a house cheaply, you are actually hurting the value of those houses. I don't want to do anything to hurt the value of their house. If I wanted to crush the housing market, I could do that so fast that people could buy houses. But you would destroy people who already have houses." Our politicians are sacrificing people in their 20s and 30s for the prosperity of boomers Let that sink in

Great, now let’s actually do it!

Germany's Merz admits: It was a serious strategic mistake to exit nuclear energy. We are now undertaking the most expensive energy transition in the entire world. I know of no other country that makes things so difficult and expensive as Germany.

A killer feature would be for this coming USDH stable to natively accrue interest, just like IBKR distributes yield on idle cash

Probably the most important indicator of the cycle and quite opaque data - a pity it was last updated a week ago though?

We study how family background shapes life outcomes across the socioeconomic spectrum in Sweden. Using population-wide data and sibling correlations, we find that siblings from low-SES families are much more similar to each other than siblings from high-SES families.

🚨Gaza | June 13, 2025 Israel has killed more than 50 Palestinians across the Strip since dawn, amid a second consecutive day of total internet blackout. For the first time since the genocide began, both the Palestinian Ministry of Health and Gaza’s Government Media Office have been unable to issue public updates—likely due to the collapse of communications. Israeli forces have continued bombing relentlessly—from Jabalia, Beit Lahiya, and Beit Hanoon in the north to Khan Younis and so-called “safe zones” like al-Mawasi in the south. Sahat English reports that Israeli gunboats opened fire on tents along Gaza’s seashore. Footage from the scene shows four people killed and ten wounded. There are also reports of a massacre in the Shati Refugee Camp after tents were bombed. Earlier today, Anadolu Agency reported that 10 Palestinians were killed near a school shelter in Khan Younis. Reporting from Deir el-Balah, Al Jazeera journalist Hind Khoudary said the blackout is crippling emergency response, with ambulances unable to locate the wounded. Crews aren’t receiving calls from residents, making it nearly impossible to coordinate rescues. “It’s affecting lives being saved,” she said. Khoudary noted that Israeli forces “open fire every single morning” on Palestinians trying to collect aid from the Israeli- and U.S.-backed Gaza “Humanitarian” Foundation. “Earlier today, there were a lot of Palestinians killed at the sites,” she said. With Gaza under blackout, little footage is getting out—but the massacres are ongoing.

Thank you, thank you, thank you Dr @Tanyaalih for your courage, passion and eloquence. Watch EVERY MINUTE of this extraordinary interview about the grotesque murder of 9 siblings in Gaza. I just don't know how she holds it together. /1

“… anyway, so I’m very bullish this new SPAC I’m working on for selling weed at scale. Memo attached.”
I think marijuana is the most insidious of drugs. It is legal in many states, is socially acceptable to many and is relatively easy for kids to hide, access and consume (vape, gummies etc). But the science is beginning to tell a very ugly story. We should have never legalized it. But now that it is, I hope we do something to mandate standard toxicity and concentration labeling at a minimum. This stuff is turning a plurality of our kids into zombies. scientificamerican.com/artic…
