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.

Outside the body is one thing. The EU banned it as a food additive last year and some US states are considering it too. TiO2 has genotoxic traits, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8323234/

I always found it odd that my acrylic paint and my toothpaste share this ingredient.

Dihydrogen monoxide too!

Water isn't genotoxic. Titanium is. It's fair to be concerned about chemicals when the chemicals cause objective harm.

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 think it means Individual Contributor (level) 6 - which is described as "Staff SWE" by https://www.levels.fyi/?compare=Google&track=Software%20Engi...

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...

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.

I believe they meant replacing the special * syntax with a use of apply so that there was no special syntax to achieve that functionality at all.

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.

This is great, thanks for sharing.

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.

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.
