• How to Visualize Ping Responses on Linux With gping

  If you don't fancy the text-based output of the ping command, consider installing gping, a CLI utility that visualizes ping responses on Linux.

  ping is a simple yet essential tool for diagnosing network issues on Linux. It can help you check your network connection, see if a remote machine is online, and play a vital part in analyzing connectivity issues, such as dropped packages or high latency.

  But as important as the ping command is, it's not the most interesting to look at, and interpreting its output in a useful way can be difficult. gping is a graphical command-line utility with additional features which make it easy to visualize ping responses from multiple targets.

• 10 Useful tar Commands in Linux With Examples | LinuxCloudVPS Blog

  This blog post will show you the ten most used tar commands in Linux with examples.

  The tar command in Linux provides archiving functionality for compressing or decompressing archive files and modifying and maintaining them. With the tar command, we can create tar, gz, bz2 and gzip archives. Administrators use these commands when they want to save some disk space on the servers or when they are migrating files over two host machines.

  In this tutorial, we are going to execute the tar commands on Ubuntu 22.04 OS, but you can choose any Linux distro. Let’s get started!

• Creating a modifiable gzipped disk image | Richard WM Jones

  Dusty Mabe set me a challenge yesterday. He wants to create several compressed disk images that have slightly different content, but are otherwise mostly the same. The disk images are large and compressing them takes a long time (30 minutes each, apparently), so ideally what we’d want to do is compress the disk image just the once and then do the updates on the gzipped image.

  Modifying a file which has already been compressed is not usually possible.

  However if we make some relatively uncontroversial assumptions and accept a few limitations then we can create a compressed disk image which is modifiable in this way, certainly for gzip and xz (I need to investigate zstd).

• Improve Website Performance Using gzip and Nginx on Ubuntu 22.04 | LinuxHostSupport

  A website’s performance depends on many factors, and choosing a suitable web server is one of them. You can choose from many web servers, like Apache, LiteSpeed, Nginx, etc.

  Nginx is an open-source web server, it was initially developed by Igor Sysoev and released in October 2004. In Nginx, gzip compression can significantly reduce the size of transmitted data to website visitors.

  Modern web browsers support GZIP compression by default. However, we need to configure our server to serve the compressed resources to our website visitors properly. Without a proper configuration, it could make your server load higher and even slower. This article will show you how to improve website performance using GZIP and Nginx on Ubuntu 22.04.
