  • How to use the history command on CentOS 8

  • How to Create EC2 Duplicate Instance with Ansible | Linux Journal

    Many companies like mine use AWS infrastructure as a service (IaaS) heavily. Sometimes we want to perform a potentially risky operation on an EC2 instance. As long as we do not work with immutable infrastructure it is imperative to be prepared for instant revert. One of the solutions is to use a script that will perform instance duplication, but in modern environments, where unification is an essence it would be wiser to use more common known software instead of making up a custom script. Here comes the Ansible! Ansible is a simple automation software. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. It is marketed as a tool for making complex changes like zero-downtime rolling patching, therefore we have used it for this straightforward snapshotting task.

  • Cryptographic Autonomy License (CAL-1.0): My first license review [Ed: Openwashing licences (i.e. faking 'Open Source' for proprietary software nonsense)]

    The bookmark was creeping on my browser’s toolbar for months. “Cryptographic Autonomy License” CAL-1.0 on the Open Source Initiative webpage.

The Cryptographic Autonomy License is one of newest Open Source licenses on the block. The Open Source Initiative approved it in February 2020. This license also made ripples when it came through. But the question I had, and could not find a clear answer to, was why is it so interesting? This blog post is my attempt to do a casual coffee-table review of the license. If you agree or disagree, I encourage you to leave a comment and share your opinion and why!
