One more cool article about the fmt package: io.reader, printf, println functions, formatters, work with strings and STDIN. All that you want to know, but were afraid to ask about the output printing process in GoLang 🙂

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.

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 :)

Hello, there! One GoLang feature proposal about immutability is here 🙂
It’s a really interesting idea with pros and cons inside, it has a good explanation, use cases and examples for the following proposed changes: fields, arguments, variables, return values, methods reference types (Pointers, slices, maps, channels). This approach merits attention if you are interested in paths of GoLang development, so, have a good reading! 😉
