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.

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 do some main board stocks become GEM stocks?

Course Introduction：Main Board stocks will not automatically turn into GEM stocks. The Main Board and GEM are two different sectors of the Chinese stock market, with different listing standards and trading rules. The main board market is mainly for mature companies, and the listing standards are relatively high, including financial indicators, company size, operating years and other requirements. The GEM is mainly for innovative and growth-oriented enterprises, and its listing standards are relatively low, but it has higher requirements for the company's innovation capabilities and technological content. If a company was originally listed on the main board, but due to certain reasons, such as a decline in company performance, violation of listing rules, etc., it may be suspended from listing or forced to delist. In this case, the company's shares will no longer trade on the main market. On the other hand, if a company meets the GEM listing standards and decides to
