This is what happens when you apply a DC voltage across a Josephson junction.

It is called "AC effect" because when we apply a DC voltage, it produces an alternating current on the device.

By looking at the Josephson equations, we see that $V(t)=k$ a positive constant, then $\phi$ just increases linearly without bound.

Therefore, from the first equation:we see that the current will just vary sinusoidally between $\pm I_c$.

This meas that we can use a Josephson junction as a perfect voltage to frequency converter.

Wikipedia mentions that this frequency is $484GHz/mV$, so it is very very high, so we are not able to view individual points of the sine curve separately with our instruments.

Also it is likely not going to be very useful for many practical applications in this mode.

An I-V curve can also be seen at: Figure "Electron microscope image of a Josephson junction its I-V curve".

If you shine microwave radiation on a Josephson junction, it produces a fixed average voltage that depends only on the frequency of the microwave. TODO how is that done more precisely? How to you produce and inject microwaves into the thing?

It acts therefore as a perfect frequency to voltage converter.

The Wiki page gives the formula: en.wikipedia.org/wiki/Josephson_effect#The_inverse_AC_Josephson_effect You get several sinusoidal harmonics, so the output is not a perfect sine. But the infinite sum of the harmonics has a fixed average voltage value.

And en.wikipedia.org/wiki/Josephson_voltage_standard#Josephson_effect mentions that the effect is independent of the junction material, physical dimension or temperature.

All of the above, compounded with the fact that we are able to generate microwaves with extremely precise frequency with an atomic clock, makes this phenomenon perfect as a Volt standard, the Josephson voltage standard.

TODO understand how/why it works better.

A pre-Jesus-like figure, likely possibly a mentor or competitor with Jesus.

He would have deserved a scene in Jesus Christ Superstar (1973).

Matthew 10:16-23 Coming Persecutions, where Jesus before being persecuted warns his disciples that there is evil in the world and that they must be aware of it, all while being pure at heart:

One is reminded of Nick Leeson.

One things must be said: the root cause of all of this is the replication crisis.

This is why he managed to go on for so long.

People felt it was normal to have to try for one or two years to replicate a paper.

Turkish Islamic sect.

Ciro Santilli once was at student a hackthon, where he proposed working on OurBigBook.com to others.

The only person who showed interest was a follower of the sect.

It seems that they put a lot of emphasis in education.

Also, their self-name is Hizmet, which translates as "service".

That day, Mr. Fethullah Gülen gained some Cirocoins.

Hardcoded and unique network addresses for every single device on Earth.

Started with 48 bits (6 bytes), usually given as 01:23:45:67:89:AB but people now encouraged to use 64-bit ones.

How they are assigned: www.quora.com/How-are-MAC-addresses-assigned Basically IEEE gives out the 3 first bytes to device manufacturers that register, this is called the organizationally unique identifier, and then each manufacturer keeps their own devices unique.

One of the least evil of the big tech companies of the early 21st century, partly because Sergey Brin's parents fled from the Soviet Union and so he is anti censorship, although they have been tempted by it.

Google only succeeds at highly algorithmic tasks or at giving infinite storage to users to then mine their data.

It is incapable however of adding any obvious useful end user features to most of its products, most of which get terminated and cannot be relied on:

This also seems to extend to business-to-business: twitter.com/MohapatraHemant/status/1343969802080030720 ex-Googler tells how they lost the cloud to Amazon.

More mentions of that:

Too many genius engineers. They need some dumber people like Ciro Santilli who need to write documentation to learn stuff.

Ciro Santilli actually attempted two interviews to work at Google in the early 2010's but very quickly failed both on the first phase, because you have to be a fast well trained coding machine to pass that interview.

Ciro later felt better about himself by fantasizing how he would actually do more important things outside of Google and that they would beg to buy him instead.

He was also happy that he wouldn't have to use Google crazy internal tools: someone once said that Google's tools make easy tasks middle hard, and they also make impossible tasks middle hard. TODO source.

But whatever the case: Ciro will not, ever, spend his time drilling programmer competition problems to join a company.
