> Minikube is a free and open-source tool that allow us to setup a single node Kubernetes cluster locally on our system. Minikube is only used for learning Kubernetes and allow developers to build their test environment locally on their system.
> A checksum value is a short data block derived from a larger one. MD5 (Message Digest 5) checksum values are used to verify the integrity of files in Linux.
> First off, any SSD you want to use today will support what's called 'Deterministic Read After TRIM (DRAT)' (sort of cf), where the SSD will always return a fixed result when you read data after a TRIM operation. Some SSDs also promise to always return zeros in this situation; this is 'Deterministic read ZEROs after TRIM', variously abbreviated as 'DZAT', 'RZAT', or 'DRZAT'. These are the (S)ATA versions, but NVMe has a similar system. All of these mean that once you TRIM the entire drive, the previous data on the drive can't be read through normal means, so someone who gets your drive and puts it in a computer will get garbage (or possibly errors on NVMe drives).
> PHP is a general purpose scripting language that is used mainly for web development, it is pragmatic, easy to learn and use, it is constantly evolving with a wide community of developers who are in charge of enriching this popular programming language with new features, therefore it is constantly evolving.
> Iostat is a popular system monitoring and performance analysis tool widely used on Linux systems. It provides detailed information on system resources such as CPU utilization, disk I/O, and network utilization, which can help system administrators monitor and optimize their systems' performance.
> Brave Browser is a free and open-source web browser created by Brendan Eich, the co-founder of Mozilla and the creator of JavaScript. It is designed to provide users with a fast, secure, and privacy-focused browsing experience.
> Secure Copy Protocol (SCP) is a command-line tool that transfers files securely between remote servers using the SSH (Secure Shell) protocol. It is a convenient and secure way to move files between servers, particularly for system administrators who manage multiple servers.
> Extracting tar files is a fundamental task in Linux and Unix-based systems. The tar utility is designed to consolidate multiple files into a single archive file. This archive file can be compressed with various algorithms such as gzip, bzip2, and xz. After compression, the archive file can be extracted using the untar command.
