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).

The studio executives are trying to extinguish quality movies because they only want predictable mainstream cliches that can churned out inexpensively in enormous volume from AI on a regular schedule.

I’d rather reduce the weight on my face by combining the computer with the external battery.
