Golang Log Example | Log Package In Go

In computing paradigm, a log file is a file that records either events that occur in the operating system or other software runs or messages between the different users of communication software. Logging is an act of keeping a log. In the simplest case, messages are written to the single log file. Let’s deep dive into Golang Log Example.

Golang Log

Large corporations that depend on the distributed systems often write their applications in Go to take advantage of the concurrency features like channels and goroutines (e.g., Heroku, Basecamp).

If you are responsible for building or supporting the Go applications, a well-considered logging strategy can help you to understand user behavior, localize errors, and monitor the performance of your applications.

What's new in the go 1.15

Go announced Go 1.15 version on 11 Aug 2020. Highlighted updates and features include Substantial improvements to the Go linker, Improved allocation for small objects at high core counts, X.509 CommonName deprecation, GOPROXY supports skipping proxies that return errors, New embedded tzdata package, Several Core Library improvements and more.

As Go promise for maintaining backward compatibility. After upgrading to the latest Go 1.15 version, almost all existing Golang applications or programs continue to compile and run as older Golang version.

Send Email in Golang using Go Mail Package | Emails in Go

Send an email with Golang using a popular package Gomail.

Gomail is a simple and efficient package to send emails. It is well tested and documented.
Gomail can only send emails using an SMTP server. But the API is flexible and it is easy to implement other methods for sending emails using a local Postfix, an API, etc.
Install Gomail: go get gopkg.in/gomail.v2

Golang Array Example | Arrays in Go Tutorial Explained

Golang array is a fixed-size collection of items of the same type. The items of an array are stored sequentially and can be accessed using their index. If we want to declare an array in Go, a programmer specifies the type of the elements and the number of items required by an array.

Golang array example

Golang programming language provides a data structure called an** array**, which can store the fixed-size sequential collection of items of the same type.

The array is used to store the collection of data, but it is often more useful to think of the array as the collection of variables of the same type.

Instead of declaring individual variables, such as no1, no2, …, and no99, you declare one array variable such as numbers and use no[0], no[1], and …, no[99] to represent individual variables.

“Go Has Indeed Become The Language Of Cloud Infrastructure“ - Rob Pike

Introduction

We spoke to Rob Pike, the co-author of the Go programming language, about a career spanning four decades, the evolution of Go over the last ten years, and into the future.

The Interview

Evrone: Unlike many developers today, you started your career decades ago at Bell Labs. What’s been the biggest change in the way we develop software that you can think of, given your rare perspective?

**Rob: **The scale is much bigger today. Not just of the computers and the network, but the programs themselves. All of Unix version 6 (circa 1975) fits comfortably on a single RK05 disk pack, which has just over 2MB of storage, with lots of room left over for user software. And that was a fine computing environment, or at least seemed like one at the time. Although I can, of course, explain much of the growth, it is astonishing and perhaps not all of it is justified.
