The Traditional Way Of Learning In the olden days, you had to go to school or college to educate yourself. In the classroom, listen to the lectures, make notes and enjoy some discussions with the lecturer and classmates. At home, you would refer to textbooks and complete the work suggested in the curriculum. Other than college, you had and have the option of private tuition. There are many brick and mortar training academies that supplement the colleges and universities.

Data Structures And Algorithms Data Structures: A data structure is a technique of storing data in a computer so that it can be accessed and modified efficiently. Algorithms: An algorithm is a step-by-step instruction to perform a task. Why Should I Learn Data Structures And Algorithms? Enhance your problem solving skills. Write efficient code that is performant and scalable. Specialized fields: machine learning, data science, artificial intelligence and other engineering fields deal with complex data and require efficient processing.

Introduction This is an anchor post about machine learning and artificial intelligence. Observations On AI Revolution in Text Generation: Generative AI is making significant strides in text production, promising a surge in the quality and quantity of text-based content. This encompasses everything from blog posts and articles to comprehensive reference books, transforming how information is created and disseminated. Advancements In AI-Generated Imagery: The evolving capabilities of AI in image generation are noteworthy.

In a previous series of blog posts, we discussed the Kubernetes objects typically used to run a web application. We covered, Namespace, Pod, ConfigMap, Secret, Service, Deployment, ServiceAccount, Ingress, PDB, HPA, PV, PVC, Job and CronJob. In this post, we will discuss some fundamental building blocks for the Kubernetes cluster administration: RBAC objects. In most situations, Kubernetes API server is started with the flag --authorization-mode=RBAC which enables RBAC in the cluster.

Introduction We have the host machine with the OS Ubuntu 22.04. On this PC or server, we will create two virtual machine guests: myubuntu2204test01 having static IP of 192.168.122.146 myubuntu2204test02 having static IP of 192.168.122.147 The guest VMs will use the default network created by libvirt. The gateway IP for the default network is 192.168.122.1. We will achieve automation using libvirt, qemu and cloud-init. To go through the article and exercise, you should have a rudimentary understanding of Linux system administration and networking.

This is a guide to write a Kubernetes controller. We will kick off by inspecting the Kubernetes API from inside a pod within the cluster. Minikube suffices for this exercise. But you can conduct the exercise to any Kubernetes cluster. The controller watches events related to Kubernetes pods using the Kubernetes API. When there is a new event, the controller logs the event’s type and the name of the affected pod.

So, you have an SSH key pair. The public key has been added on to the server. On the client, ie your laptop/desktop you have your private key. For some reason, your private key has not been loaded into memory. All you have to do is start the ssh-agent and then load the key into memory via ssh-add. Step 1: Start the agent eval $(ssh-agent) Step 2: load the key into memory

Using Linux KVM, Expose Virtual Guests On The LAN Audience: The blog post is for beginner to intermediary Linux system administrators. You should have a thorough understanding of the shell commands and be comfortable on the command line be able to install and configure packages, etc. be able to start and stop services using systemd be familiar with Linux configuration files be able to set Linux kernel parameters using sysctl be able to enable and disable Kernel modules be comfortable installing and using guest VMs using libvirt You should have a rudimentary understanding of networking concepts and tooling such as

Purpose Of Having Naming Conventions For An Ansible Project Consistency: Adopting a naming convention standardizes naming across the project and organization. This makes it easier for developers to switch between projects. Typically, an organization with an infrastructure team will have several Ansible projects and source code repositories. A developer working on one such Ansible project can seamlessly switch to another given a standard naming convention. Error Reduction: With improper naming there can be pitfalls.

Ansible Prerequisites Before jumping on to learning Ansible, have a firm grounding in Linux system administration and shell scripting. You can use Ansible for a lot of automation projects. The primary target audience for this blog post are DevOps engineers, IT infrastructure engineers and system administrators who create and manage IT infrastructure to run workloads. A good understanding of YAML is required before starting to write Ansible playbooks. A background in at least one programming language helps.
