Go: A Beautiful Mess

originally published on medium.com. I published it here because medium is blocked in some countries. An old school guy like me love statically typed language, even I tasted the convenience of dynamic typed languages for handling data with complex structure like JSON or operating data with SQL/NoSQL. The statically typed language avoids many ambiguous issues and let us figure out the mistake before before unit test reports it. So I love Go in many pieces, it leverages many concepts from other languages, has a easy understanding struct types, great tool set for production…etc, and most importantly, it’s easy to write and performance will not let you down, but I also got confused sometimes and found many ambiguous parts in Go.

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.

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.EntryNew() grid.AttachNextTo(textentry, imgview, gtk.POS_BOTTOM, 1, 1) btnChoose, _ := gtk.ButtonNewWithLabel("Choose An Image") grid.

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 ?

Is Go better than PHP?

First, “web development” is a very broad term and might, therefore, mean a lot of things including server-side rendered HTML pages, JSON APIs, microservices, etc. Second, let’s define what makes a programming language qualify for web development. (sorted by importance) Ecosystem Tooling Libraries Developer market Success stories Maintainability Language design Ecosystem consistency Performance Asynchronous execution for increased throughput Low latency Raw number-crunching performance Infrastructure Hosting and deployment Memory usage and cost in general So, let’s get ready to compare!
