Ways to fix issue 2003 (HY000): Unable to connect to MySQL server 'db_mysql:3306' (111)

I recently tried to containerize my FastAPIPython server (also for replication/doubling purposes).

Below is the code snippet of the server database initialization connector in the application fromfastapiimportFastAPIimportmysql.connectorapp

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri

Shortest way to convert all PHP types to string

I'm writing a general system that I hope can one day be applied to fields like medicine (i.e. it's "scientific"). I think the best way is to represent all the data in php with strings (true will be "true", false will be "false" and so on). The reason for this is that in php any value has a unique string representation (such as the php code itself). I post this question to speed up the design process of this program. Some values are easily converted to strings: numbers, booleans, etc. Some are not easy: objects, arrays, resources. I think the transfer object and

GPT Store encountered problems immediately after its opening: copycats, volume brushing, and prohibited content emerged one after another.

Course Introduction：I never expected that the newly opened GPTStore would be famous for being "chaotic". No, in the "Trending" list, an application called NewGPT-5 suddenly appeared, and it ranked first. However, sharp-eyed netizens immediately discovered the clue - it was fake! OpenAI official side also dealt with this matter extremely quickly, and the fake GPT5 has now completely disappeared. Even if you click on the original link, the "open method" is 404: As soon as this incident came out, many netizens came to complain.

The first government review of ChatGPT may come from the US Federal Trade Commission, OpenAI: not yet trained GPT5

Course Introduction：Produced by Big Data Digest ChatGPT has become a "target" in the AI ethics community after receiving an open letter signed by hundreds of well-known artificial intelligence experts, technology entrepreneurs and scientists. On March 30, the U.S. Federal Trade Commission (FTC) received a new report from the Center for Artificial Intelligence and Digital Policy (CAIDP), requesting an investigation into OpenAI and its product GPT-4. The complaint states that the FTC already stipulates that the use of artificial intelligence should be "transparent, explainable, fair, and empirically reasonable while promoting accountability," but claims that OpenAI's ChatGPT4 "does not meet these requirements" and is "unauthorized." is biased, deceptive, and poses a risk to privacy and public safety."
