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.

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.

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

14 priorities and trends for CIOs in 2024

Course Introduction：GenAI will become the most important technology trend in 2024, and for CIOs, reviewing new tools, configuring infrastructure, responding to new risks, and delivering new user experiences will become top priorities. While most vendors are rolling out new GenAI capabilities, it can be difficult for CIOs to determine whether they are truly valuable rather than leading to costly failures. Therefore, CIOs need to develop a business case for these tools to ensure they deliver real value. New GenAI tools and infrastructure will impact CIOs far beyond expectations.
