PostgreSQL: Migrating from int to bigint

Resources

PostgreSQL zero-downtime migration of a primary key from int to bigint (with Ruby on Rails specific notes)

• This approach requires setting up a PostgreSQL trigger to keep the mirrored bigint column in sync with the existing int column until it is time to swap them out.

"""A quick benchmark comparing the performance of:

- msgspec: https://github.com/jcrist/msgspec
- pydantic V1: https://docs.pydantic.dev/1.10/
- pydantic V2: https://docs.pydantic.dev/dev-v2/

The benchmark is modified from the one in the msgspec repo here:
https://github.com/jcrist/msgspec/blob/main/benchmarks/bench_validation.py

I make no claims that it's illustrative of all use cases. I wrote this up

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

Se você quiser adicionar mais algum tópico deixe seu comentário, o objetico é facilitar para os iniciantes ou aqueles que buscam dominar JavaScript, quais tópicos são importantes para dominar JavaScript.

São tópicos para quem sabe o minimo de JavaScript (declarar variáveis), a ordem em que eles aparecem são por importância para o dominio como um todo. Mesmo que você já tenha experiência com JS, recomendo que leia os links de cada tópico para fortalecer suas bases teóricas e ter um comportamento mais profundo da linguagem.
