I continue to looking for interesting articles about the IO package and today I’ve found one more good post in last Medium Digest by Vladimir Vivien from Kubernates. It calls “IO Streaming в GoLang”.
Main points of it:
- A structure and internal processes of io.Reader and io.Writer;
- Custom implementations of them;
- Useful types and packages for IO(os.File, os.Stdout, os.Stdin, and os.Stderr, io.Copy(), etc);
- Pipe writers and readers.

This article is completely of technical info, examples and illustrations 😀 Enjoy reading 📖!

Hi there 👋 and have a good weekend to everyone! I like to share some interesting pet projects and one of them calls GoCraft. Here is an GoLang implementation of famous Minecraft game 🙂 and it has some features:

- Basic terrain generation
- Add and Remove blocks.
- Move and fly.

#news #games #development

System requirements from Readme are:
macOS, Ubuntu/Debian-like Linux, CentOS/Fedora-like Linux but I think you are able to try to launch it on Windows if you want 😉

Good day 👋 I would like to share following 7 advices in short article by Kartik Khare how to increase your code quality in GoLang. Of course, before using it you should understand reasons for each advice in the post. As example Kartik writes:

#6 Use int as keys instead of strings in Map.

It’s a good way but here we can get optimization for optimization 🤔

Why are goroutines not lightweight threads?

Kartik Khare shows us his meaning about goroutines, lightweight threads and their difference in GoLang. There are no code examples inside but good thoughts about parallelism, threads and useful links at the end of the article :)

Hi, there! I found one interesting topic, which calls

The State of Developer Ecosystem Survey in 2018

Here is a whole report about GoLang usage by Jetbrains company includes frameworks, libraries and testing analytics. You are also able to pick another languages and technologies because this report contains only to the developers who chose Go as one of their three primary programming languages.
