Santos, São Paulo, Brazil Updated 2025-07-16
Ciro Santilli lived in Santos from about the year 1998 to 2007, with a 10 month hiatus in Coventry, UK, until he went to the University of São Paulo.
Santos is the nearest beach city to São Paulo City, and for this reason:
Ciro idolizes Santos as the perfect location to live nature-wise due to its amazing wide sandy beach, in which Ciro spent endless hours walking on the sand and on the largest beachfront garden in the world (archive), meditating, and playing some soccer after school was over. Santos is also the city where Pelé first played professionally.
Ciro has visited Santos several times after leaving Brazil. Doing this gives him a weird feeling of having a separate life, in which time passes 2 weeks every few years. Of course, as your family grows, it gets harder and harder to go back home, and your family members might want to just go travel to more interesting places than just stay at your wonderful beach which you love in part due to nostalgia.
Ciro is also fond of the concept of the small public buildings near the beach garden (postos de praia), which serve different cultural activities: library, comic book store, art cinema, surf school. It is such a shame that the library and comic book ones are in such bad shape as of 2020, old books and poor people who go there to sleep a bit in the barely working air conditioning. Ciro fantasizes how those could instead be cultural hubs for the gathering of the brightest artists, and scientists, of town. Maybe they are just too small. Maybe it is not within the realm of possibility of public service. Maybe, we should focus instead in the poorer regions, far form the beach. But the dream remains.
Santos only has one natural defect: mosquitoes. By the sea it is fine because the wind is strong, and they don't like salt water. But anywhere else, you will be eaten alive, and maybe get dengue, Ciro got it once. Gene drive, please.

Canal 5 on the beach by VicTrindade (2017)
Source. This is one of Santos 7 old canals, which are still in use and serve to reduce floodings in the city, which are caused by the strong tropical rains that fall on the city. This is particularly important to keep the mosquito population under some control. All canals were built in the first third of the 20th century, except canal 7 which is from 1968[ref]. The canals have normally very shallow water when it is not raining, and since it is rain water they are basically clean. There are other canals which are/were used for sewage, but then are not open air. The canals now serve as handy reference points and practical avenues in town, as well as being surrounded with nice trees that provide shade and drop small inedible purple fruit that will stain your car for all eternity. They do scar the beach line a bit it must be said, but it's part of the charm of the city, and they serve as good reference points for runners.
The National Byway Updated 2025-07-16
It runs along quiet roads, rather than a mixture of roads and tracks like the National Cycle Network, making it more appropriate for road bikes.
TODO interactive online app? Ahh, those charities that try to make money by individual transactions... when they die, nothing will be left of all their work.
Edit: noticed that it is on by default on OpenStreetMaps web UI under the "Cycle Map" layer marked at "NB".

Is the only atom that has a closed form solution, which allows for very good predictions, and gives awesome intuition about the orbitals in general.
It is arguably the most important solution of the Schrodinger equation.
In particular, it predicts:
The explicit solution can be written in terms of spherical harmonics.

Sequelize Updated 2025-07-16
Some usage examples under: Section "Sequelize example".
As of 2021, this library is extremely painful to use. It does feel semi-mature, but there are just too much horrible things going on;
Some glaring issues are listed at the horrors of Sequelize.
Cardinality Updated 2025-07-16
The size of a set.
For finite sizes, the definition is simple, and the intuitive name "size" matches well.
But for infinity, things are messier, e.g. the size of the real numbers is strictly larger than the size of the integers as shown by Cantor's diagonal argument, which is kind of what justifies a fancier word "cardinality" to distinguish it from the more normal word "size".
The key idea is to compare set sizes with bijections.
Second generation immigrant Updated 2025-07-16
Our definition: first generation to be born in country parent immigrated to.

Being a first generation immigrant, this cartoon does make Ciro think about the future of his children.
Immigrating is incredibly time consuming and direclty limits what you can do in life later on. One can only hope that their children will take advantage of the new opportunities provided to them.
shakacode/react_on_rails Updated 2025-07-16
Uses Redux, while reactjs/react-rails appears to do that more manually
Live instance: www.reactrails.com/ with source at: github.com/shakacode/react-webpack-rails-tutorial Not the most advanced web-app (a gothinkster/realworld-level would be ideal). Also has clear dependency description, which is nice.
Oh, and the guy behind that project lives in Hawaii (Ciro Santilli's ideal city to live in), has an Asian-mixed son, and two Kinesis Advantage 2 keyboards as seen at twitter.com/railsonmaui/status/1377515748910755851, Ciro Santilli was jealous of him.

Worked on Ubuntu 20.10.
The UI is a bit too buggy to bear.

It's just too charming, and has some deep themes.
Sequence alignment Updated 2025-07-16
Sequence alignment is trying to match a DNA or amino acid sequence, even though the sequences might not be exactly the same, otherwise it would be a straight up string-search algorithm.
This is fundamental in bioinformatics for two reasons:
Server Side Public License Updated 2025-07-16
Created by MongoDB, attempts to be even more restrictive than AGPL by more explicitly saying that indirect automatic requests are also included in the "you must give source" domain: opensource.stackexchange.com/questions/8025/difference-between-mongodb-sspl-and-gnu-agpl
The base use case is:
which is what MongoDB is trying to ensure, which sounds fair.
