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

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.

I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops.

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

Penetrating Eigenlayer Token Economics: A New Social Consensus Mechanism to Solve Where ETH Can't

Course Introduction：After long-awaited announcements, Eigenlayer finally announced more details about its token economy today and announced that it will distribute 15% of EIGEN tokens to users who have previously participated in re-staking through linear unlocking. Does the EIGEN token itself have more value? What exactly is it used for? What impact can it have on re-staking and even the entire Ethereum ecosystem? The answers all lie in this more than 40-page token economy white paper released by Eigenlayer. Unlike general projects that scribble a few token release diagrams when introducing the token economy, Eigenlayer spent a lot of time explaining the role of the EIGEN token and its relationship with the ETH token in a detailed, meticulous and even technical way.
