Davidman had a lot of influence on the writing of "Till We Have Faces," but it was published before her death. "A Grief Observed" is the book Lewis wrote about the grief that followed.

The 1918 influenza pandemic killed tens of millions, disproportionately affecting young and healthy adults. Does that not qualify as super-deadly?

As a datapoint, yesterday's lockout affected my Apple ID that is based on a ~25-year-old mac.com address.

Christchurch is the logistics hub and support base for the US presence in Antarctica, so I believe all US facilities on the continent conduct their work in that time zone.

Maybe this has been fixed in recent models, but ten years ago it was easy to experience baffling laptop sleep states if you happened to set a working macbook down on top of another, similarly-sized macbook with its lid closed.

Similar experience here. I went to a new dentist who had one of those machines and he told me I needed at least nine fillings. I declined and found someone else. Over 16 years and multiple moves/new dentists since then, maybe three of those teeth have actually needed fillings.

The detector is made of thousands of light sensors arranged in a a km-scale 3D grid. When a neutrino interaction causes a flash of light inside this volume, multiple sensors detect the photons with nanosecond-level time resolution. So a 3D map can be made of where the light started and how it moved over time.

For a macroscale analogue, imagine a large 3D grid of microphones all recording sound. If you fired a cannon from inside this grid and looked at the waveforms from all the microphones, you could work out where the cannon was, and also form a pretty good guess of what direction it was pointed.

I recall reading about the craft using gasoline as an incompressible floatation fluid, but I hadn't realized the scale: 100 tons of gasoline, making up 2/3s of the craft's mass.

The timing and text of this announcement certainly suggest that they've been gearing up to be a launch title on Apple's headset.

Which makes me wonder if Apple's been funding development, perhaps for some time.

A local hobby shop sold a kit with ten bits, 1.0mm down to 0.1mm, which I bought on a lark several years ago.

The middle sized bits are occasionally useful to (carefully!) finger-drill a tiny hole through a plastic part. They're rigid, very sharp, but pretty breakable if you're not careful.

The 0.1mm bit is so small that it's upsetting even to look at. I've never taken it out of the case.
