If the active elements were convex instead of concave, I can imagine this being useful for people with visual impairments. How does this compare to existing technologies for braille displays?

The present US government would delight in finding a new way to funnel more yachtloads of cash to Larry Ellison, legally or otherwise, as long as someone in the regime gets something out of it.

The greatest enemy of a free market is a successful capitalist.

In taxicab geometry, π=4 https://en.wikipedia.org/wiki/Taxicab_geometry

Cosine similarity of two normalized vectors is just the length of the projection of one vector on the other. That gives a very intuitive geometric meaning to cosine similarity. https://en.wikipedia.org/wiki/Vector_projection

No, you're probably thinking of this: https://news.ycombinator.com/item?id=18340693 (He4 exposure temporarily messes up iPhones by glitching their MEMS clocks)

It boils down to the DoJ wants to force "Super Apps" like WeChat. That is something I absolutely don't want because then everyone will be forced to use it, like in China. Super Apps are what's intrinsically anticompetitive.

Yeah. It must have been a typo for “have been found”.

For decades, Gaussian basis functions have been used for quantum chemistry: https://en.wikipedia.org/wiki/Basis_set_(chemistry)

Water famously does not always stay stable as a water molecule and in fact has extremely complex behavior. https://en.wikipedia.org/wiki/Self-ionization_of_water

How long until it freezes you until you accept the EULA update? https://news.ycombinator.com/item?id=37587510

Calculating the mean field of a thousand electrons is easy for a classical computer. Calculating the exchange and correlation energies of a thousand interacting electrons is not. Quantum computers would have an enormous advantage there.

There used to be two forms of letter s, long s when medial and short s when final, similar to the two forms of sigma in later Greek. The integral sign derived from this. https://en.wikipedia.org/wiki/Long_s

When sugar dissolves in water, it stays sugar. When salt dissolves in water, it becomes separate Na+ and Cl- ions.

Most of what's in these handouts, and much, much else, is just in their heads--at least the part that's relevant to their field, obviously an organic chemist is going to have slightly different things memorized than a geochemist. For things that you have to look up, for decades the first thing you reach for would be the CRC Handbook https://en.wikipedia.org/wiki/CRC_Handbook_of_Chemistry_and_... although it's on the web now https://hbcp.chemnetbase.com/contents/ContentsSearch.xhtml?d... as well as other reference materials.

The airlines’ pricing irrationality is akin to the https://en.wikipedia.org/wiki/I486SX where it cost Intel extra money to disable the floating point unit.

Some ingredients of life likely came from deep space. That doesn’t mean that life did.

A number of MacBook users leave their laptops shut and plugged into external monitors a large fraction of the time, making the sensor awkward to get to.

You’re mixing up two different models. You’re thinking of the $55 Yubico YubiKey 5C NFC https://www.yubico.com/product/yubikey-5-series/yubikey-5c-n... What they chose is the $29 Security Key C NFC by Yubico https://www.yubico.com/us/product/security-key-c-nfc-by-yubi... (note the word YubiKey does not exist in this model name) which does not have that feature.

Source: My company started providing these to employees and I was also initially confused by Yubico selling two different products with almost the same name.

It’s not an amalgam (that means a mercury alloy) or any metallic alloy. It’s an oxide (more complicated than that but there’s more oxygen atoms than metal atoms).
