What is the underlying language of Golang
In the earliest times, Golang was implemented in C and assembly.
Later Golang implemented bootstrapping and rewrote the compiler, so now it is implemented using Golang itself.
If you invent a new language CNifeLang, you first need to write a CNifeLang compiler in an existing language, for example, use Golang; you write a CNifeLang in Golang The compiler can successfully compile any legal CNifeLang source code into an equivalent target program. Then use CNifeLang to write a program, which has the same function as the compiler you wrote in Golang. Use the compiler implemented in Golang to compile the program, and you will get a CNifeLang compiler implemented in CNifeLang. Because the function of this program is exactly the same as the compiler written in Golang, you can use this compiler to compile CNifeLang, so CNifeLang implements bootstrapping.

The Mistral open source code model takes the throne! Codestral is crazy about training in over 80 languages, and domestic Tongyi developers are asking to participate!
Jun 08, 2024 pm 09:55 PM
Produced by 51CTO technology stack (WeChat ID: blog51cto) Mistral released its first code model Codestral-22B! What’s crazy about this model is not only that it’s trained on over 80 programming languages, including Swift, etc. that many code models ignore. Their speeds are not exactly the same. It is required to write a "publish/subscribe" system using Go language. The GPT-4o here is being output, and Codestral is handing in the paper so fast that it’s hard to see! Since the model has just been launched, it has not yet been publicly tested. But according to the person in charge of Mistral, Codestral is currently the best-performing open source code model. Friends who are interested in the picture can move to: - Hug the face: https
Golang framework vs. Go framework: Comparison of internal architecture and external features
Jun 06, 2024 pm 12:37 PM
The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.
How to save JSON data to database in Golang?
Jun 06, 2024 am 11:24 AM
JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.
What are the best practices for error handling in Golang framework?

Best practices: Create custom errors using well-defined error types (errors package) Provide more details Log errors appropriately Propagate errors correctly and avoid hiding or suppressing Wrap errors as needed to add context
How to find the first substring matched by a Golang regular expression?
Jun 06, 2024 am 10:51 AM
The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].
