Installing golang compiler in linux machine

Download the Go 1.12.1 binary archive suitable for your operating system from the official Go website (https://golang.org/dl/).

wget https://dl.google.com/go/go1.12.1.linux-amd64.tar.gz

Extract the downloaded archive to the /usr/local directory:

sudo tar -C /usr/local -xzf go1.12.1.linux-amd64.tar.gz

Add the Go binary directory to your system’s PATH environment variable by editing your shell profile file (e.g. ~/.bashrc or ~/.zshrc) and adding the following lines:

export PATH=$PATH:/usr/local/go/bin

Reload your shell profile to apply the changes:

source ~/.bashrc

go version

output:

go version go1.12.1 linux/amd64

lets print HelloWorld! from go
package main

import "fmt"

func main() {
	fmt.Printf("HelloWorld!")
}

Output:

HelloWorld!

Boosting Golang Application Performance with Query Result Caching

In the realm of Golang application development, optimizing database queries is a critical aspect of ensuring smooth and efficient user experiences. One powerful technique to achieve this is Query Result Caching . In this blog post, we will delve into query result caching strategies, focusing on caching frequently executed queries in an in-memory cache (using Redis as an example). You'll learn how to reduce database load and improve response times, all while enhancing your Golang application's performance. The Power of Query Result Caching Consider a scenario where your Golang application frequently fetches data from a database. Without caching, every request to retrieve the same data results in a database query, even if the data hasn't changed since the last request. This can be resource-intensive and lead to slower response times. Query result caching is the practice of storing the results of frequently executed queries in an in-memory cache, such as Redis or Memcached....

Enhancing Database Security and Performance with Parameterized Queries

In the world of database programming, security and performance are paramount concerns. One technique that addresses both of these concerns is the use of parameterized queries or prepared statements. In this blog post, we'll explore the significance of parameterized queries, their role in preventing SQL injection, and how they can potentially improve query execution speed. We'll provide practical examples to illustrate the power and versatility of this essential query optimization technique. The Importance of Parameterized Queries Parameterized queries , also known as prepared statements , are a mechanism in which placeholders are used for data values in SQL queries. These placeholders are later bound to actual data values when the query is executed. Parameterized queries offer several crucial advantages: Protection Against SQL Injection: One of the primary benefits of parameterized queries is their ability to prevent SQL injection attacks. By separating SQL cod...

Profiling CPU Usage in Go: Boosting Performance

Image
Profiling CPU Usage in Go Programs Profiling CPU usage in Go allows you to measure the time your program spends executing various functions and code paths. This insight is invaluable for optimizing your code. Go provides built-in tools to help you with this. To get started with CPU profiling, you'll need to: Import the net/http/pprof Package : This package exposes the profiling functionality via HTTP endpoints. Include it in your code like this: import _ "net/http/pprof" Start an HTTP Server : You'll want to start an HTTP server that serves profiling data. go func() { log.Println(http.ListenAndServe("localhost:6060", nil)) }() Instrument Your Code : Use the runtime/pprof package to start and stop CPU profiling within your application: import ( "net/http" _ "net/http/pprof" "os" "runtime/pprof" ) func main() { go func() { log.Println(http.Lis...
