In the previous tutorial, we discussed multiple concepts related to pointers in C programming language. One of the concepts we discussed was an array of pointers.

Fedora IoT is an upcoming Fedora edition targeted at the Internet of Things. It was introduced last year on Fedora Magazine in the article How to turn on an LED with Fedora IoT. Since then, it has continued to improve together with Fedora Silverblue to provide an immutable base operating system aimed at container-focused workflows. […]

This is the first article in a series about interprocess communication (IPC) in Linux. The series uses code examples in C to clarify the following IPC mechanisms: read more

Mercurial is a distributed version control system written in Python. Because it's written in a high-level language, you can write a Mercurial extension with a few Python functions. There are several ways to install Mercurial, which are explained in the official documentation. My favorite one is not there: using pip. This is the most amenable way to develop local extensions! read more

I'm no stranger to diagnosing hardware problems on Linux systems. Even though most of my professional work over the past few years has involved virtualization, I still enjoy crouching under desks and fumbling around with devices and memory modules. Well, except for the "crouching under desks" part. But none of that means that persistent and mysterious bugs aren't frustrating. read more

MICROSOFT WAS NOTIFIED BUT DECLINED TO PATCH. Page said he notified Microsoft about this new IE vulnerability on March 27, but the vendor declined to consider the bug for an urgent security fix in a message sent to the researcher...

In the first part of this series, we introduced something called idempotency, which can provide the ongoing improvements to your server estate’s security posture. In this article, we’ll get a little more hands-on with a look at some specific Ansible examples.

Ansible is a simple automation tool that automates software application deployment, cloud provisioning, and configuration management. In this tutorial, we're going to show you how to create basic Ansible Playbook for provisioning the LEMP Stack on Ubuntu 18.04 Server.

We recently interviewed Joe Doss on how he uses Fedora. This is part of a series on the Fedora Magazine. The series profiles Fedora users and how they use Fedora to get things done. Contact us on the feedback form to express your interest in becoming a interviewee. Who is Joe Doss? Joe Doss lives […]

The concept of pointers is indeed one of the very important concepts in the C programming language. Up until now, we have discussed several aspects of pointers in C. Expanding on that, in this tutorial, we will be discussing a few more pointer concepts.

A few months ago, I was asked to design some posters for a local Free Software Foundation (FSF) event. Richard M. Stallman was visiting our country, and my friend Abhas Abhinav wanted to put up some posters and banners to promote his visit. I designed two posters for RMS's talk in Bangalore.  read more

Four years ago, I interviewed Nathan Currulla, co-founder of ByWater Solutions, a major services and solutions provider for Koha, a popular open source integrated library system (ILS). read more

Scrum is built on the three pillars of inspection, adaptation, and transparency. Our empirical research is really the starting point in bringing scrum, one of the most popular agile implementations, to smaller teams. As presented in the diagram below, we are now taking time to inspect this framework and principles by testing them in real-world projects. read more

Network File System (NFS) is a popular distributed filesystem protocol that enables users to mount remote directories on their server. The system lets you leverage storage space in a different location and write onto the same space from multiple servers in an effortless manner. It, thus, works fairly well for directories that users need to access frequently. This tutorial explains the process of mounting NFS share on an Ubuntu 18.04 server in an simple and easy-to-follow steps.
