Transaction retries are inevitable, as some sQL isolation levels
Doesn't seem to have any simple built-in mechanism?
Example: nodejs/sequelize/trigger_count.js
There is of course no built-in support for SQL TRIGGERs in Sequelize, but we can add our own: stackoverflow.com/questions/29716346/how-to-create-a-trigger-in-sequelize-nodejs/76215728#76215728
The normal navigation to them was paywalled, but the static files are served without login checks if you know their URL. One way to go about it is to search by prefix on the Wayback Machine: web.archive.org/web/*/https://www2.physics.ox.ac.uk/sites/default/files/contentblock/2011/06/03/*
The last handbooks we can find are 2020/2021, they might have move to a new more properly paywalled location after that year.

At least they have a fucking clear course schedule unlike the undergrad.
Good overgrown section in the middle of Fresnel's biography: en.wikipedia.org/w/index.php?title=Augustin-Jean_Fresnel&oldid=1064236740#Historical_context:_From_Newton_to_Biot.
Particularly cool is to see how Fresnel fully understood that light is somehow polarized, even though he did not know that it was made out of electromagnetism, clear indication of which only came with the Faraday effect in 1845.
spie.org/publications/fg05_p03_maluss_law:
At the beginning of the nineteenth century the only known way to generate polarized light was with a calcite crystal. In 1808, using a calcite crystal, Malus discovered that natural incident light became polarized when it was reflected by a glass surface, and that the light reflected close to an angle of incidence of 57° could be extinguished when viewed through the crystal. He then proposed that natural light consisted of the s- and p-polarizations, which were perpendicular to each other.
Matches the quantum superposition probability proportional to the square law. Poor Étienne-Louis Malus, who died so much before this was found.
Have a look at some interesting examples under nodejs/sequelize/raw/many_to_many.js.

Ciro's word of caution for 2019 aspiring system programmers: Should you waste your life with systems programming?
This is basically a direct consequence of backward design.
The higher the level you can operate at, the better.
The ideal level to operate at, and one of humankind's greatest ambitions is "AGI, make me money", the highest possible level.
Only go down a level when it seems necessary.

Can produce two entangled particles.
Described for example in lecture 1.
Each transaction isolation level specifies what can or cannot happen when two queries are being run in parallel, i.e.: the memory semantics of the system.
Remember that queries can affects thousands of rows, and database systems like PostgreSQL can run multiple such queries at the same time.
Good summary on the PostgreSQL page: www.postgresql.org/docs/14/transaction-iso.html

Free University Brighton has been working since 2012 to provide an alternative and for the last five years we’ve been running ‘freegrees’. These are University level courses, open to all regardless of qualification. Our courses range from 4 week long introductory courses aimed at First Years (people who have never been to University before) to 12-week long Humanities, Social Sciences and Philosophy courses that rival anything in a ‘traditional’ University. We do this all with no money exchanged anywhere - no fees, no debt.
Shut up and show us the courses.
There are unlisted articles, also show them or only show them.
