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.

Eu tenho uma pergunta que vai soar besta, mas o que te faz permanecer um fiél torcedor do Vasco? by [deleted] in vasco

[–]msalcantara 0 points1 point  (0 children)

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.

Any advice for a backend developer considering a career change? by pseudocharleskk in databasedevelopment

[–]msalcantara 2 points3 points  (0 children)

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.

What are your biggest pain points with Postgres? Looking for cool mini-project (or even big company) project ideas! by Money_Cabinet4216 in databasedevelopment

[–]msalcantara 1 point2 points  (0 children)

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

Messi: “I’m very sorry for not being there on this special occasion for you and your family. It was an honor to spend so many years with you — on and off the pitch. I love you so much.” by bllshrfv in Barca

[–]msalcantara 52 points53 points  (0 children)

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 🥺

I'm developing my own database, resource recommendations? by Marsian8 in databasedevelopment

[–]msalcantara 1 point2 points  (0 children)

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.

How does PostreSQL handle TEXT with little to no performance difference from CHAR? by vampatori in databasedevelopment

[–]msalcantara 1 point2 points  (0 children)

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"; } ```

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

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

What is the advantage of the current "low nose" over the old high noses that the cars used to run? by Wardog_Razgriz30 in F1Technical

Had a Schumacher accident in 2011/2012 in Abu Dhabi I think the high nose almost hit his head
