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.

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 Do Command Lines Still Exist ?

GUI (graphical user interface) is easy to use and goodlooking. But CLI (command line interface) is faster and easier to automate. Advantages of Command Line over Graphics Graphics are fancy but lack clarity and prone to errors and crashes and uses alot of resources (RAM, CPU and GPU). Here are some advantages. Lightweight Text Interface If you accomplish a task like converting mp4 to mp3 on command line using ffmpeg, it will be faster than using any other GUI program such as Format Factory (for Windows OS).
