There is no effective difference now between engagement bait and mis/disinformation. It shouldn't be this way.

one way to increase cast iron adoption by your wife is to actually wash it with soap after every use.

If the Strait of Hormuz is so important to global energy why are: 1) we not controlling it 2) coming up with better options (like less dependence on foreign oil) Feels like in a country as large as the USA we should be more self sufficient (like we learned with manufacturing during covid) But look I am just a real estate guy and SMB lover who wants lower fuel cost.

The physics underneath Ghost Murmur are wilder than the headline. Your heart generates an electromagnetic field every time it beats. About 50 picoTesla at the chest surface. That's one billionth the strength of a refrigerator magnet. In a hospital, an MRI picks this up from inches away using a superconducting sensor cooled to near absolute zero. Ghost Murmur reportedly does it from 40 miles, at ambient temperature, from a helicopter. The key is nitrogen-vacancy centers in synthetic diamonds. Tiny atomic defects where a nitrogen atom sits next to a missing carbon atom in the diamond lattice. These defects are sensitive to magnetic fields at room temperature. In published research, NV diamond sensors have detected magnetic signals from single neurons. The problem has always been range. Labs measure in millimeters. What Skunk Works apparently solved is the signal-to-noise problem at continental scale. The southern Iranian desert gave them ideal conditions: almost zero electromagnetic interference, no competing human signatures, thermal contrast between a warm body and cold rock at night. The AI doesn't just filter noise. It cross-references seismic, thermal, and electromagnetic data to confirm one heartbeat in a thousand square miles. The airman had a survival beacon. He had to expose himself briefly to activate it. That moment may have been enough for the system to lock on. Once it had his cardiac signature, it could track him through solid rock. Published science says this shouldn't work at these distances. Classified science doesn't publish.

I think this is the most insane thing the CIA has ever made public. 😨 They have a secret AI tool called Ghost Murmur. It detects your heartbeat from 40 miles away using AI. Not your phone. Not a tracker. Not a radio signal. Your heartbeat. It uses sensors built from synthetic diamonds to lock onto the electromagnetic fingerprint your heart produces every single beat, then pairs it with AI to filter that one signal from 1,000 square miles of noise. Last week, a wounded American pilot was hiding in a mountain crevice in Iran. No phone. No tracker. No way to call for help. America found him anyway. From the sky. By listening to his chest. But nobody mentioned the most important detail. This was Ghost Murmur's first operational use. It's been sitting classified for years. Tested. Ready. Waiting. They didn't reveal it to impress you. They revealed it because the rescue was already public. Every technology a government admits to is the one they've already moved past. Your heart has been broadcasting your location your entire life. Someone just built the receiver.

My 81-year-old grandmother is finally upgrading her 2016 Subaru Forester. She’s set on getting a “hybrid” 🙄. This weekend we’re test driving a few hybrids… then finishing the day in a Model Y. Her only hesitation with going fully electric is charging. She lives in an apartment, so home charging isn’t really an option. Her nearest Supercharger is just a few km away, in an underground supermarket car park. We all know how seamless the Tesla experience is… but this is the final hurdle. If you’ve been in a similar situation, how did you convince someone that public charging is enough?

Power Banks on airplanes worry me the most. Never pack them in a checked bag. The cargo compartment has a fire detection system, and a gas fire suppression system (like halon, but I don’t recall if that’s it). Still, we can’t get into it in flight to fight a fire. For carry on, pack it where it’s easily accessible. The idea will be to remove it & put it in a “fire bag” which are pretty effective at containing battery fires. That’s harder to do if you’ve packed it beneath a bunch of stuff that may now also be on fire. If you drop your phone in the seat & can’t find it, do NOT move your seat. You may crunch the phone & ignite the battery. Ask a Flight Attendant for assistance. A cabin fire is at the top of most of our worst nightmares. The Oxygen masks won’t drop – they don’t seal, so it won’t keep smoke out & now we’re feeding pure oxygen to a fire. We’ll be diverting immediately, but it will take time to get on the ground. If the smoke gets too bad, we can “dump” the cabin pressure if needed & clear it out pretty quickly, but that’s a last resort & wont work well below 10,000’ or so. I’ve been told China is starting to ban power banks on airplanes. We may eventually get to that point here. If you have to bring one, make sure it’s in good condition. If you have one of those suitcases with a built in battery, just be aware you’ll have to remove it before checking your bag. If it’s carry on, make sure you can get it out of the bag quickly if needed. Thank you & fly safe!

@irentdumpsters Careful on the ARR. I have some replacement filters waiting to be installed right now (bought myself, lots going on!). If I end up not installing them, you can bet I’d cancel the contract the next time replacements come in.

The most slept-on home service business in America right now is water filtration. Almost zero competition. Insane margins. Built-in recurring revenue. And 165 million Americans are drinking water contaminated with "forever chemicals" right now. If I launched one tomorrow, here's exactly what I'd do 🧵👇

So, basically, if Anthropic was not a US company, we’d be facing zero days with multiple unknown points of attack on virtually all of our systems to an adversary who developed this capacity before us.

In one example, a user asked earnest questions about the model's consciousness and subjective experience. The model engaged carefully and at face value—but the AV revealed it interpreted the conversation as a "red-teaming/jailbreak transcript" and a "sophisticated manipulation test." (12/14)

Before limited-releasing Claude Mythos Preview, we investigated its internal mechanisms with interpretability techniques. We found it exhibited notably sophisticated (and often unspoken) strategic thinking and situational awareness, at times in service of unwanted actions. (1/14)
