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).

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

Cars transformed into 'mobile game arcades”

Course Introduction：Cars have transformed into "mobile game arcades". Is this what users need, or is it because manufacturers are not doing it right? On June 11, 2021, Musk showed the actual game screen of "Cyberpunk 2077" through the 17-inch car screen in the car at the Model SPlaid delivery ceremony (picture from Tesla). In the era of software-defined cars, It's not unusual for something like this to happen. However, there is a prerequisite behind this - the Model SPlaid at that time was equipped with AMD Navi23 GPU core, equipped with 8GB GDDR6 video memory, and the overall performance specifications were not much different from Sony PS5. Musk proudly announced at the press conference that Tesla Model SPlaid was the best, The fastest, safest and most sustainable vehicle with
