Is Gio UI Ready for Production ?

Gio UI is a graphics library built in Go programming language. Gio builts user interfaces in immediate mode which is popular in games industry. Gio UI library is efficient and fast. The documentation on the official website is good for experienced developers, but not good enough for beginners. Yes. Gio UI library is ready for production. But its current bottleneck problem is documentation and examples. So, we — here in ValueInBrief — will provide examples, samples and tutorials in the following days.

The Only Introduction to Go (Golang) You Need

Go, or also called Golang, is absolutely trendy, and rightly so. It is not as difficult to learn as C or C++, but still quite fast, and has a great community & many interesting and helpful packages and libraries. The language was also developed by some of the brightest minds in the computer science world at Google. These are probably enough reasons to look at the language in which Docker and Kubernetes were written.

Interactive Go Programming With Jupyter

For the past few years, the programming language Go (golang) is growing in popularity. I was a big fan of Python and I primarily used Python in my hobby projects three years ago. Now, I use Go instead of Python because I can be productive with Go from small-scale hobby projects to very large-scale projects in a large company. In the same period, Python is also growing in popularity as machine learning and data science became important.

Plain Socket Communication Between Two Go Programs, the Easy Way

Because there was an interesting discussion at reddit, suggesting using SSE, gRPC, Message queues (and there are plenty of others), I thought about making an article on (comparing) those communication protocols. But in the end, I decided otherwise. I see all those protocols as something that is adding more code to your project. I mean, you have to import something. You have to use an additional library. And I wanted something, that have less code below.

WebSocket Communication Between Two Go Programs, the Easy Way

This article was written with one idea in mind: to show you, how to make a communication between two Go programs, using WebSockets. The simplest possible way. When using WebSockets, one program has to act as a server. But there can be numerous other programs as clients. In this article we will create one server and one client. WebSocket Server The code for server is pretty simple. And because we don’t want to reinvent the wheel, we will use gobwas module.

Go: functions, methods, pointers and interfaces

This article was created especially for my son, who had hard times understanding using pointers and interfaces. To make the explanation complete, I added (with his help) two things: functions and methods. I see those two as a complement to pointers and/or interfaces. Or vice versa. This explanation is divided into six parts, each part adding onto previous part. I tried to make it all as simple as possible. The basics We will start with something very simple.

7 Reasons You Should Try Go

This article is written with 20+ years spent in development, 10+ years actively writing in Java, 7+ years actively writing in C# and 3+ years actively writing in Go. This article is a personal opinion. This article advocates you, to try and use Go language. Speed of development When I am about to write a piece of software nowadays (and I can surely write it in all three languages), I will always choose Go.

Why Go is better than Rust ?

First, it’s very important to say that both Go and Rust are absolutely excellent programming languages. My goal here is not to criticize any language. In this article, I’ll try to give a brief overview of where I think Rust is the ideal choice, and where I think Go is a better alternative. If you had to sit down and think of the programming languages which were best aligned with the motive to develop secure, microservice favoring frameworks and apps, you would again find yourself staring at the two languages.

How to Create File Chooser in Gtk using gotk3 ?

If you just want the complete code snippet, here is it. package main import ( "github.com/gotk3/gotk3/gdk" "github.com/gotk3/gotk3/gtk" ) func main() { gtk.Init(nil) win, _ := gtk.WindowNew(gtk.WINDOW_TOPLEVEL) win.SetTitle("sample app") win.Connect("destroy", func() { gtk.MainQuit() }) grid, _ := gtk.GridNew() win.Add(grid) imgview, _ := gtk.ImageNew() pbuf, _ := gdk.PixbufNewFromFileAtScale("./img/default.png", 400, 400, true) imgview.SetFromPixbuf(pbuf) grid.Attach(imgview, 0, 0, 1, 1) textentry, _ := gtk.

How to Tune Garbage Collector in Go Language ?

How to set the GOGC value ? You can set its value in the terminal like this. GOGC=200 Or you can change it in yaml file of the environment variable when using docker or kubernetes. What is the default value of GOGC ? The default value of GOGC is 100 which means that the garbage collection process will run when the allocations doubled from previous allocations count. What can I do to reduce the effect of garbage collection in Go ?
