maybecorrect··on SR-71 Blackbird Speed Check Story
Correcting myself, I was thinking of Zinc Oxide. But it's still pretty inert. I wouldn't want a plate of it, but whatever level of toxicity it possesses, it is low enough that it requires careful study to detect.

I'm pretty sure titanium dioxide is pretty inert. It's a primary ingredient in sunscreen and diaper cream.

Otherwise, I agree with your point.

maybecorrect··on Why Google+ Failed
I think it means Individual Contributor (level) 6 - which is described as "Staff SWE" by https://www.levels.fyi/?compare=Google&track=Software%20Engi...
maybecorrect··on Why Doctors Reject Tools That Make Their Jobs Easier
I think the common thing between restaurant POS systems and EMR is that they aren't optimized for the user, they're optimized for management.

I thought the trick was you spin the egg, then stop it - a raw egg will continue to rotate because the fluid inside is moving, but a cooked egg won't restart because nothing inside it is moving.

This link shows a hardboiled egg spinning on its end, but otherwise seems to agree with me, though it doesn't quite contradict you: http://www.planet-science.com/categories/experiments/magic-t...

maybecorrect··on Asterisks in Python
It is a function - print() is being called as a function, taking a number of positional, arguments followed by named argument. I don't think you're correct about this being special syntax, except for the '*' is being used to expand a list into the positional arguments.
maybecorrect··on The First Rule of Microsoft Excel: Don’t Tell Anyone You’re Good at It
I have a joke I tell about Excel:

Excel is amazing, because it's the wrong tool for everything! Which is really impressive, since there aren't many tools you can do everything with!

I realize it's not a very funny joke, but I do think it's true.

maybecorrect··on What are “actual pictures” of atoms actually pictures of?
In the simplest configuration have a X-Y stage that you raster, along with Z axis control - generally these are all piezo controlled. Your signal is then acquired by maintaining a constant tunneling current while you raster, so you track the Z axis position as you raster.

This means that you're getting a "pseudo-height" map - if you had a surface with 2 types of atoms, both the same size, but with different tunneling barriers, you would see them appear to be different sizes.

maybecorrect··on How jumbo jet engines are made [video]
Thanks for that pointer - that is a seriously cool channel - I wasn't sure what to expect, but I'm really digging the videos discussing how to correctly assemble a jet engine.
