In its final death throes, a medium-size star spews out its guts to form an effervescent planetary nebula, thin wisps of gas and dust surrounding the now-exposed core of carbon and oxygen at the center.

So, advanced users aren't going to be running ML or Linux games on M1 machines anytime soon. But this is still an impressive achievement. … [Read more...] about Corellium ports Linux to Apple M1 Mac mini
Life isn't quite so sweet in the third row. It's not the 29.6-inch (752mm) legroom so much as the fact that you're sitting only a couple of inches above the floor and your knees nearly at face level.
