Several words about Golang

Go, also known as Golang, is a programming language developed by Google in 2009. It was designed to be a fast, statically-typed language with simple syntax, easy concurrency, and efficient memory management.

One of the main features of Go is its support for concurrent programming, which allows developers to write programs that can perform multiple tasks at the same time. Go uses goroutines, which are lightweight threads of execution, to achieve this. Goroutines are easy to create and manage, and they can communicate with each other using channels, which provide a way to send and receive data between goroutines.

Go is also known for its simplicity and readability. It has a small set of keywords and a straightforward syntax, making it easy for new developers to learn and for experienced developers to read and understand code written in Go.

In addition to its concurrency and simplicity, Go is also known for its performance. It compiles to native machine code, which means it can execute quickly without the need for an interpreter. Go also has efficient memory management, with a garbage collector that helps to keep memory usage low.

Go has a growing community of users and developers, and it is widely used in the industry for a variety of applications, including web servers, distributed systems, and networked programs. It is also commonly used for developing command-line tools and utilities.

Overall, Go is a powerful and efficient programming language that is well-suited for a wide range of applications. Its support for concurrent programming, simplicity, and performance make it an attractive choice for many developers.

Go has a number of built-in types, including integers, floating-point numbers, strings, and booleans. It also supports composite types such as arrays, slices, and maps. Go does not have classes, but it does have structs, which allow developers to define custom types with fields and methods.

Go also has a number of built-in control structures, including if statements, for loops, and switch statements. It also has support for defer, which allows developers to specify a function to be executed just before the surrounding function returns.

Go has a strong emphasis on testing and debugging, with a built-in testing framework and support for debugging tools such as the delve debugger. Go also has a number of formatting tools, such as gofmt, which automatically formats Go code according to a set of predefined rules, and goimports, which automatically manages imports for Go packages.

In addition to its standard library, Go has a large and growing ecosystem of third-party libraries and frameworks. These include libraries for web development, database access, networking, and more.

Go has been widely adopted in the industry, and it is used by companies such as Google, Dropbox, and Docker. It has also gained popularity among open-source developers and is used in a number of high-profile projects, including Kubernetes and Terraform.

In conclusion, Go is a powerful, efficient, and easy-to-use programming language with a growing community of users and developers. Its support for concurrent programming, simplicity, and performance make it a strong choice for a wide range of applications.

One of the advantages of Go is its cross-platform support. Go programs can be compiled for a variety of platforms, including Windows, macOS, Linux, and even embedded systems. This makes it easy to write code that can be run on multiple platforms without the need for platform-specific modifications.

Another advantage of Go is its focus on simplicity and readability. Go has a small set of keywords and a straightforward syntax, making it easy for new developers to learn and for experienced developers to read and understand code written in Go. This simplicity also helps to reduce the risk of introducing bugs and other issues into code, as there are fewer opportunities for mistakes.

Go is also known for its strong support for testing and debugging. Its built-in testing framework makes it easy to write and run unit tests, and its support for debugging tools such as delve makes it easier to identify and fix issues in code. This can help to improve the quality and reliability of Go programs.

In addition to its simplicity and support for testing and debugging, Go is also known for its performance. It compiles to native machine code, which means it can execute quickly without the need for an interpreter. Go also has efficient memory management, with a garbage collector that helps to keep memory usage low. This can make Go programs faster and more efficient than programs written in other languages.

Overall, Go is a powerful and efficient programming language with a strong focus on simplicity and reliability. Its support for concurrent programming, simplicity, and performance make it a strong choice for a wide range of applications.

Go is a statically-typed language, which means that all variables must have a specific type defined at compile time. This can help to prevent bugs and other issues that can arise when variables are used in unexpected ways. Go has a number of built-in types, including integers, floating-point numbers, strings, and booleans. It also supports composite types such as arrays, slices, and maps.

One of the key features of Go is its support for concurrent programming. Go uses goroutines, which are lightweight threads of execution, to achieve this. Goroutines are easy to create and manage, and they can communicate with each other using channels, which provide a way to send and receive data between goroutines. This makes it easy to write programs that can perform multiple tasks at the same time, which can be useful for improving the performance and scalability of Go programs.

Go also has a number of built-in control structures, including if statements, for loops, and switch statements. It also has support for defer, which allows developers to specify a function to be executed just before the surrounding function returns. This can be useful for managing resources and cleaning up after a function has completed.

In addition to its standard library, Go has a large and growing ecosystem of third-party libraries and frameworks. These include libraries for web development, database access, networking, and more. This can make it easier for developers to build complex applications without having to reinvent the wheel.

Overall, Go is a powerful and efficient programming language with a strong focus on simplicity and reliability. Its support for concurrent programming, simplicity, and performance make it a strong choice for a wide range of applications.

New social network

I like Twitter, and I am used to it. But in my opinion, Musk killed Twitter, and most important he killed the spirit of Twitter.

 I decided to create a new social network that will be open and free for everyone!

This social network will be written on Golang. So it will be a reason to write more posts on this blog.

I will try to write about all aspects of creating a social network.

SSH Menu

 Today I want to present to you one of my utilities which were written to automate some routine processes.

This utility is called SSHMenu.

URL: https://github.com/ZanMax/sshmenu

For me, it's very hard to keep all my servers in memory. So I decided to write this utility. 

It will help you to keep the list of your ssh connections in one place.

So enjoy ;)

P.S. I have more utilities written on Go in my Github.

Generics in Golang

Why generics are so important and why they can save you tons of time. 

Let's try to figure it out.

Start with a simple example: 

func sumOfSome(input int64) int64 {
	var sum int64
	for _, v := range input {
		sum += v
	}
	return sum
}

But what to do if we need not only int64?

In this case, generics will help us.

type Number interface {
	float64 | int64 | int
}


func sumOfSome[T Number](input []T) T {
	var sum T
	for _, v := range input {
		sum += v
	}
	return sum
}

First of all we need create an interface with all types (float64, int64, int) which we whant to sum.
