It would be interesting to create a solution using two or three cameras mounted on the corners of the monitor, creating a simulated image of a camera watching the user from the center of the screen. I wonder how clear and realistic an image can be generated this way, and how much the quality would depend on the size of the monitor and the distance to the face. What do you think?

Visited Princeton to see Princeton University. A very pleasant town, not at all like typical America. Founded in 1746, it has expanded since: everywhere you look, there is Romanesque, Gothic architecture, Empire style, modern. In one of the photos – Albert Einstein’s house. Simple, no plaque, private residence. It seems Albert did not want to turn himself into an idol, and even left instructions to scatter his ashes in a place known only to his family. So you won’t find him in the local cemetery. The house where, after Einstein, Nobel laureate Frank Wilczek also lived, was sold in 2012 for 1.4 million dollars to the university where Einstein worked (IAS)

This is what a toilet looks like at a car wash. Price-wise, it’s a regular wash. Well, maybe a buck more expensive than the one at the gas station.

Toilets here are almost always free. I can’t remember the last time I paid. Probably, there are still pay toilets in mega-cities. But you can’t find those in our village.

By the way, in five years, I have not yet encountered a toilet anywhere without toilet paper. I mean everywhere, including toilets at the beach, in the forest, in parks, at gas stations. The last time I saw a real mess was during a car trip from California to Las Vegas, but that was six years ago. Apparently, they have some quirks 😉

Watched in one breath today. Seven episodes, over four hours.

The story of three nuclear programs: German, American, and Soviet. Despite being a viewpoint from “Channel One”, I don’t want to argue with 99% of what was heard. Strangely, they only briefly mentioned the Rosenbergs, who were executed on the electric chair in the USA, and since then, questions about the fairness of their execution crop up occasionally. A lot of attention was given to the Soviet nuclear program (Kurchatov, Khariton, Kapitsa, Joffe, Flerov), the Manhattan Project (Oppenheimer, Groves), the role of Niels Bohr, the German nuclear program (Heisenberg, but oddly not Otto Hahn), espionage scientists infiltrated into the heart of the Manhattan project (Fuchs, Hall, and others like Harry Gold – not a scientist, but a spy), supplying developments to the USSR “to prevent war”. Strangely, there was nothing about Landau and Sakharov.

It was interesting to learn about George Gamow, who tried everything to escape the USSR: skiing to Finland or kayaking from Crimea to Turkey, but nothing worked out. Eventually, due to an oversight, he was allowed to go on a business trip and he defected to the USA, where he further helped the Americans make the hydrogen bomb. In contrast, the USSR did not allow Petr Kapitsa to return to Cambridge where he lived and worked.

Another thing I liked: “After returning from Munich, Chamberlain said on the airplane stairway, ‘I have brought back peace.’ It meant – it’s time to urgently prepare for war.” Seems like everyone understood it already 🙂

In general, an interesting series, highly recommend. It can generally be watched at 2x speed.

Last night I went out hunting for gasoline. Apparently, some Russian hackers (according to the FBI) or non-Russian hackers (according to Biden) recently broke a pipeline across half the country, and as of yesterday, more than half of the gas stations were depleted. I barely (on the fourth try) found a gas station with a long line, which only had ultra 93 for $3.5 per gallon (usually, we pay $2.8). The state governor has declared a state of emergency. We don’t have public transportation in our areas, and stores are not within walking distance, so it’s really bad for many. The government has now allocated money and introduced tax breaks to fuel companies to give them more flexibility in supplying gas stations.

We are observing. In fact, it looks like the IT guys just missed a virus (ransomware), and it seems that the information security there was below par (roughly speaking, like staff listening to Spotify and surfing the web on critical process computers). And then one day, the computer doesn’t boot up, displaying the message “give us money or we won’t turn it on.” And here again the question arises – what about backups? What about a contingency plan? So, I really don’t see anyone’s fault except for colonial pipeline. Of course, it is not excluded that the virus was written for a specific target, and somewhere social engineering worked. But that’s what security experts are hired for.
