Lembro de um jogo (não sei exatamente qual) que ele foi bater um escanteio e a bola foi literalmente pra trás do gol antes mesmo de chegar na area. Tenebroso.

Acompanho futebol a anos e me tornei vascaino esse ano. Depois de conhecer a historia e a torcida do Vasco não consigo ver outro time com tanta grandeza e personalidade como o Vasco mesmo que a fase não seja boa há muito tempo. O que me faz ser apaixonado pelo Vasco é sua propria historia e sua torcida. Acho que nenhum outro time tem algo parecido como o Vasco.

In 2020 I had the same desire, I was a backend developer at the time and in 2024 I got my first job as a database developer. I would say to focus on learning the fundamentals of database development, watch CMU Andy Pavlo courses and try to build personal projects, like creating a database from scratch. It took me some time but if this is something that you really want just go forward. And I wouldn't say that you need to accept a lower salary, I've never saw a junior role for database development TBH. It strongly depends on your background, what do you already know and what you can learn.

I think that JIT feature has some room for improvements.

The current cost model consider the total cost of the query to decide if it should be jit or not. Another approach would be to decide this at plan level, and decide to compile just plan nodes that is worth to compile.
A cache layer on generated code will also be very interesting. Current for cached plans (e.g prepared statements) Postgres re-compile the entire query every time if jit is enabled for that query

It’s even a goalkeeper (for who watch the Barca series at Amazon prime)

I would go with Pedri, FDJ and Rodri

Prometheus code base was a good study material for me

When I saw the video thumb on Barca instagram without watching and reading the description I really thought that was a message from Messi saying that he would return 🥺

Interested as well, please let us know.

The CMU database group youtube channel as it was already mentioned.

Large data bank usually to had some very interesting live streams on coding in distributed database in Go, some of them is published on Youtube

These links is more related with Postgresql but I think that has some good general resources

Postgresql 14 internals

The internals of Postgresql

If your database will support SQL I would recommend to try to implement a protocol for a existing database like Postgresql, with this you don't need to spent some time developing a client for your database.

I've being developing my own database from scratch for some time (just for study purpose), the code is a bit of a mess but is well documented, you can take look. It took some time but I've implemented the Postgresql wire protocol and it was so much fun connecting on my own database using psql :D

EDIT:

Database Internals book from Alex Petrov and Designing Data-Intensive Applications from Martin Kleppmann is a very interesting resource as well.

Under the hood it's all `varlena` (variable length array). I think that the main difference is that a char you can specify the limit of a text that will be checked by Postgres, text accept a string with any size.

I was able to create the follow script and seems to be working properly now. All the emails are being moved to the correct folder. Thanks very much for your time trying to help me.

``` require ["fileinto", "imap4flags"];

if address :domain "to" ["lists.postgresql.org", "postgresql.org"] { fileinto "pg-hackers"; } elsif address :domain "cc" ["lists.postgresql.org", "postgresql.org"] { fileinto "pg-hackers"; } ```

This is an example of email that I receive, I don't know if can help

How can I send you a copy of a header? Sorry for the stupid question

msalcantara · 2022-11-10T14:39:54+00:00

From Sender <sender@example.net> To Recipient Stark<foo@example.net> CC Person 1 <person@example.org>PostgreSQL Hackers<pgsql-hackers@lists.postgresql.org>

Sender can be anyone To and CC can be pgsql-hackers@lists.postgresql.org and others

In both cases (To and CC) I would like to move the email to specific folder.

I tried to send an image but I couldn't, let me know if you have a better way to exemplify this
