Microwave source Updated 2025-07-16
Microwave only found applications into the 1940s and 1950s, much later than radio, because good enough sources were harder to develop.
One notable development was the cavity magnetron in 1940, which was the basis for the original radar systems of World War II.

Sometimes you are really certain that something is a required substep for another thing that is coming right afterwards.
When things are this concrete, fine, just do the substep.
But you have to always beware of cases where "I'm sure this will be needed at some unspecified point in the future", because such points tends to never happen.
YAGNI is so fundamental, there are several closely related concepts to it:

Terrible name, but very interesting dataset:
GitHub describes the input quite well:
The model takes as input a RGB image from the robot workspace camera and a task string describing the task that the robot is supposed to perform.What task the model should perform is communicated to the model purely through the task string. The image communicates to the model the current state of the world, i.e. assuming the model runs at three hertz, every 333 milliseconds, we feed the latest RGB image from a robot workspace camera into the model to obtain the next action to take.
TODO: how is the scenario specified?
TODO: any simulation integration to it?

Upside: superconducting above 92K, which is above the 77K of liquid nitrogen, and therefore much much cheaper to obtain and maintain than liquid helium.
Downside: it is brittle, so how do you make wires out of it? Still, can already be used in certain circuits, e.g. high temperature SQUID devices.
Ciro Santilli's drug experiences Updated 2025-07-16
Ciro Santilli never did any illegal drugs, because he:so don't expect any amazing stories here.
- doesn't want to help fund organized crime. Notably, Ciro is for complete legalization of drugs of all drugs
- already has better more sustainable drugs like love, cycling, learning the natural sciences and fame. He (or more realistically, the world) chose life for him.
Like LDS believers, Ciro never drinks coffee nor smokes, and only drinks alcohol and tea sparingly, because they are all addictive drugs and bring no net increase of energy and concentration.
Ciro prefers to only enjoy a glass of tea when going out cycling on a cold day (Earl gray, with milk, no sugar), or get a half pint of beer when going out with friends to a pub.
Ciro only got reasonably drunk twice on his life:
- once when he was quite young, likely pre-10 years old, while visiting an uncle's home, and adults were having a very nice sweet and thick type of alcoholic cocktail, and Ciro drank a bit too much and that made him really really stupid
- once while studying at University of São Paulo, somehow someone was giving free beers at one of the parties (at which Ciro practiced Cirodance). And since Ciro had always been a cheap-ass, he thought, hey, this is a good chance to try it out. Ciro remembers that this made him a bit euphoric, active, very stupid, and a bit horny (though of course, he got no pussy as usual).
Later in life, around the time of his wedding, there were guests around all the time, and he was drinking beer with them all the time. Then one day, during lunch, Ciro felt a weirdly strong desire to drink one more pint. It was at this point that Ciro realized first-hand what mild, but real, alcohol addiction felt like, and he didn't get that drink, and swore from then on to never drink more than one glass a week, and only with friends at a bar after work. Richard Feynman tells a very similar story on his book Surely You're Joking, Mr. Feynman chapter O Americano, Outra Vez!, see: Section "Richard Feynman's drug use".
Ciro Santilli's formal education Updated 2025-07-16
Ciro Santilli participated in a double degree program, so he obtained have engineering degrees in both:
- 2010 - 2014: École PolytechniqueMaster 2 degree in applied mathematics.
- Ciro Santilli's undergrad studies at the University of São Paulo
Despite studying in great institutions with great teachers, Ciro feels that:
- most of what he knows came from the Internet, man pages, books and his parents
- actual projects matter much more than those pieces of paper called Diplomas. You should not do like Ciro who basically did nothing but school mandated work, but instead grow some balls and focus much more or entirely on your projects
This motivated Ciro to work on OurBigBook.com.

This is unlike atomic systems like trapped ion quantum computers, where each atom is necessarily exactly the same as the other.

One day, someone will invent a way to take the hash of a piece of hardware and see its history log, like software engineers do with version control. Until then, this is as close as you can get.

Apparently they had a separate URL as just scitable.com, so they were somewhat serious about it before shutting it down.
As of 2022 marked:RIP.
This page has been archived and is no longer updated
www.nature.com/scitable/blog/student-voices/ has last entry 2015, so presumably that's the shutdown year.
