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

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.

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.

A typical UNIX or Linux machine creates many log files during the course of its operation. Some of these contain useful information; others can be used to help you with capacity and resource planning. This article looks at the fundamental information recorded within the different log files, their location, and how that information can be used to your benefit to work out what is going on within your system.

Aitech and EFSI have teamed up to integrate NASA’s cFs (core Flight System) using the SP0-S, Aitech’s latest space-ready CompactPCI SBC and EFSI’s Linux distribution. Aitech and Embedded Flight Systems (EFSI) have announced a partnership to integrate NASA’s cFS (core Flight System) into Aitech’s modular SP0-S space CompactPCI (cPCI) SBC.
