The difference is that humans emit their own heat. Combined with our funny tendency to wear insulative clothing that can asymptotically approach zero net heat exchange with the atmosphere, acceptable temperatures skew wildly towards and beyond freezing.

Meanwhile, without some kind of acting cooling mechanism, any temp even slightly above fever temp is inevitably fatal. You can only take off so many layers. What are you going to do, take off your skin? Sweating helps us humans a lot, but evaporative cooling can only do so much to reverse the heat gradient.

50 F is excellent… with a light jacket or a blanket. Not so much if you’re naked.

The correct rebuttal is that 69 degrees is ideal ambient temperature.

The other day I learned that you can just grep an unmounted filesystem device. It will read the entire disk sequentially like it’s one huuuuge file. And it will reveal everything on that disk… whether a file inode points to it or not.

Used it to recover data from a file I accidentally clobbered with an errant mv command. It’s not reliable, but when you delete a file, it’s usually not truly gone yet… With a little luck, as long as you know a unique snippet that was in it, you can find it again before the space gets something else written there. Don’t even need special recovery tools to do it, just use dd in a for loop to read the disc in chunks that fit in RAM, and grep -a for your data.

I mean, yeah, kind of. In the same way pilots fly planes out of a stubborn sense of pride for knowing what all the flight deck controls do.
