  • The Idaho researchers observed that reversing the intrinsic angular momentum, or “spin,” of thorium-229’s outermost neutron seemed to take 10,000 times less energy than a typical nuclear excitation. The neutron’s altered spin slightly changes both the electromagnetic and strong forces, but those changes happen to cancel each other out almost exactly. Consequently, the excited nuclear state barely differs from the ground state. Lots of nuclei have similar spin transitions, but only in thorium-229 is this cancellation so nearly perfect.

    Basically, thorium-229 can be excited by conventional lasers instead of gamma rays. Instead of millions of electron volts, it takes less than 10, which means it’s more reliable and more precise.






  • I’ve had exactly two dishwashers completely stop functioning in my entire life. Both were GE post Haier and within the last 6 years. Also had a Haier made GE microwave completely fail.

    I replaced the microwave (and the matching stove) with Samsung and haven’t had one bit of trouble with either.

    I thought I had just gotten a lemon, but three separate failures within a couple of years has really soured my opinion of them. I was a lot more worried about the Samsung appliances I bought, but they’ve been a dream.

    Note: I am not recommending Samsung appliances, at all. I got an amazing deal and fully expected them to fail shortly after the warranty was up. I’ve had to repair several of my friends and family’s washers, dryers, and refrigerators. Samsung’s poor reputation is well earned, I just got lucky






  • Apples AI is mostly processed on device. That’s why it takes an iPhone 15 pro or an M-series processor. They also claim that what is processed in the cloud is neither identifiable nor stored, just processed. We will know if that’s true (at least what is being sent) as soon as it gets out into the public and we can start picking apart the traffic.

    There is no mention of opt-out or not yet, probably because we’re several months away from the actual release. I’m sure we’ll get more information before then.






  • They’ll have to get a new SAS controller unless the RAID controller has an HBA mode. Running ZFS under a RAID controller is the best way to lose all of your data.

    ZFS is wonderful but it takes quite a bit of planning and specialized knowledge to implement properly. Your fear of a failed RAID controller is a bit much, too. I’ve had to deal with a single controller failure in 30 years of IT (and I’ve done warranty work for all of the major OEMs in corporate IT for most of those 30 years)
