The provided Bash and PowerShell script helps automate the creation of Amazon Machine Images (AMIs) from existing AWS Elastic Compute Cloud (EC2) instances. This is particularly useful for creating point-in-time backups or disaster recovery. I mostly use the script to quickly clone an EC2 instance for testing or troubleshooting.

The previous article discussed installing an ACME-compatible certificate authority server. This post explains how to install step-cli (ACME client) on a client system to install the new certificate authority (CA), make it trusted, and request a TLS certificate.

Firehol is an open-source tool used to configure Linux firewalls, such as those based on iptables. Advanced users can delve deeper into the rule set with optional parameters. Firehol ensures that the rules are coherent in both directions.

In my previous post, I shared a Bash and PowerShell script that enables you to swiftly generate an Amazon Machine Image (AMI) from an EC2 instance. In this post, I will be explaining how you can promptly launch an EC2 instance using the AMI.

In my previous article, I discussed merge conflicts, specifically line merge conflicts, and how to resolve them on GitHub. In this article, I will focus on another type of merge conflict, the modify/delete conflict, and how to resolve it using Git.
