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). Before, I had just a MySQL server in a Docker container and everything was fine, but when I also made my web server a service, it couldn't connect to the MySQL server, so now the application doesn't work. Below is the code snippet of the server database initialization connector in the application fromfastapiimportFastAPIimportmysql.connectorapp

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

Build high-performance microservices using Go language

Course Introduction：Using Go language to build high-performance microservices With the rapid development of the Internet, microservice architecture is becoming more and more common in the development field. Microservices architecture breaks a single large application into multiple small, independently running services, each responsible for handling specific business functions. The advantages of this architecture are decoupling between services, flexible scalability, independent deployment and maintenance. The high performance and concise syntax of the Go language make it an ideal choice for building microservices. Go language is a compiled language with garbage collection mechanism and coroutine concurrency model.

How many Transformer layers are used in the BERT model?

Course Introduction：BERT is a pre-trained language model that uses Transformer as the network structure. Compared with recurrent neural network (RNN), Transformer can be calculated in parallel and can effectively process sequence data. In the BERT model, a multi-layer Transformer is used to process the input sequence. These Transformer layers utilize the self-attention mechanism to model the global correlation of the input sequence. Therefore, the BERT model is able to better understand contextual information, thereby improving the performance of language tasks. The BERT model consists of two main stages: pre-training and fine-tuning. The pre-training stage uses a large-scale corpus for unsupervised learning to learn contextual information of the text and obtain language model parameters.

How to create a dynamic website using PHP/javascript/HTML/CSS?

Course Introduction：Overview A dynamic website is a website where users send requests from the client to the server and render data on the backend. Since PHP is a server-side scripting language, it plays a major role in creating dynamic websites. Some dynamic websites are like website admin panel or search content for specific users. Therefore, HTML, CSS, and JavaScript are used on the client side of the website to create the user front-end, and PHP is used as the back-end scripting language to render and retrieve user data and send it back to the user on the front-end. The algorithm downloads and installs the XAMPP server from the official website. Now start the apache server to run the website on your local machine. Now open the "htdocs" folder inside the XAMPP folder in the directory. Now create a
