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.

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

Why are few people using win8? Attachment: The main reasons why Windows 8 is not popular

Course Introduction：Win10 is really easy to use, both in terms of functions and operations. I have to say that it is win8 that gives everyone this impression. Because win8 is so bad, it is simply a divided system! Microsoft can make the Metro style user interface into an independent software, similar to Windows Media Center. However, Microsoft chose to tightly integrate the Metro style user interface with the system, and users need to touch and use it whether they like it or not. Such an approach is actually to pave the way for Windows tablets. Windows8 attempts to infiltrate Metro style operating habits into users' habits, in order to make it easier for users to use Windows8 tablets. Met
