How To Setup Vagrant and Virtual Box for Ubuntu 20.04!!

A quick and easy guide to setting up a production environment on your local machine. Vagrant is an open-source software product for building and maintaining portable virtual software development environments, e.g., for Virtual Box, KVM, Hyper-V, Docker containers, VMware, and AWS.

Your First Vagrant Box

Virtual Machines, or VMs for short, are fairly popular in the Software industry and among developers. And for good reason — who would mind a disposable OS, within an OS! Right? They are fairly easy to use, allow you to run multiple OS’s on a single host OS, completely independent of each other (okay, there are some limitations in performance compared to bare metal performance, but let’s leave that aside for now).

Docker and Its Internals

Before we start talking about docker, we need to understand the problem which is solved by Docker efficiently and economically. Before Docker gained popularity.

16/32/64 Bit Assembly Programs

Ok so before we move on and jump into writing and running 64 bit programs (because all programs today are 64bit these days no? j.k.) let's have a look how to compile a simple program for each of those architectures. This knowledge should also help you better understand how to start a nano VM and "debug" problems that might arise.

Kubernetes: Virtual Clusters For CI/CD & Testing

The use of virtual clusters (vClusters) in Kubernetes, i.e. running virtual clusters inside of physical clusters, has the potential to disrupt the use of Kubernetes in a variety of settings, from cloud-native development to machine learning experiments. (For an overview of the general benefits of virtual clusters and their use cases, refer to this article). One of these settings is continuous integration/deployment (CI/CD) and the related testing of software. In this post, I will describe how virtual clusters can be used for CI/CD and testing and what their benefits are for this use case. How virtual Kubernetes clusters can solve current issues of integrating Kubernetes in CI/CD and testing processes.

x86 Handling Exceptions

In previous article we got our CPU into 64 bit mode and were able to run 64 bit programs. Our vCPU is already very useful but it doesn't deal well with issues like division by zero.
