Maintenance of the storage system is a daily job for system administrators. Linux provides users with a wealth of storage capabilities, and powerful built-in maintenance tools. However, these tools are hardly friendly to system administrators while generally considerable effort is required for mastery. As a Linux built-in storage model, LVM provides users with plenty flexible management modes to fit various needs.

Nvidia has introduced a spin-down of the Jetson TX2 compute module that falls between the TX2 and the lower-end Jetson Nano. The Jetson TX2 NX runs Linux on the […]

Raspberry Pi's single-board machines have set the mark for cheap, real-world computing. With its model 4, the Raspberry Pi can host web applications with a production-grade web server, a transactional database system, and dynamic content through scripting. This article explains the installation and configuration details with a full code example. Welcome to web applications hosted on a very lightweight computer.

I'm a fairly recent convert to Rust, which I started to learn around the end of April 2020. But, like many converts, I'm an enthusiastic evangelist. I'm also not a very good Rustacean, truth be told, in that my coding style isn't great, and I don't write particularly idiomatic Rust. I suspect this is partly because I never really finished learning Rust before diving in and writing quite a lot of code (some of which is coming back to haunt me) and partly because I'm just not that good a programmer.

In this edition of our open source news roundup, learn about open source on Mars, System76's new keyboard, a 5G open source stack, and more.

It's your computer, not ours – but we may go ahead and update it for you, says team. The Linux Mint team has introduced a fix for a memory leak it does not fully understand: restarting the Cinnamon desktop.…

Pritunl is an open-source, simple and easy-to-use VPN server that allows you to setup virtualize your private networks across data centers within a minute. In this tutorial, we will explain how to set up a Pritunl VPN Server and Client on Ubuntu 20.04 server.

You may have heard of Grafana, a time-series dashboarding tool that helps you discover what's going on in your environment. People from hobbyists to enterprise professionals like to use it for visualizations because it is open source and can accept data from myriad sources. This article describes how to use it to monitor your Raspberry Pi as an example of Internet of Things (IoT) monitoring.

As a second-semester student in systems and digital media at the Federal University of Ceará in Brazil, I was given the assignment to remake the classic Atari 2600 Breakout game from 1978. I am still in my infancy in learning software development, and this was a challenging experience. It was also a gainful one because I learned a lot, especially about applying object-oriented concepts.

Neousys’ rugged “IGT-22-DEV” IoT gateway runs the open source Linux “ThingsBoard IoT” stack on a TI AM3352 with PoE PD, DIO, serial, USB, and mini-PCIe with uSIM. After years of playing a dominant role on the pages of LinuxGizmos, the Cortex-A8-based TI Sitara AM335x has faded in recent years in favor of IoT-oriented Cortex-A7 processors […]

This is the first in a series of articles about features that first appeared in a version of Python 3.x. Python 3.0 was first released in 2008, and even though it has been out for a while, many of the features it introduced are underused and pretty cool. Here are three you should know about.

In 2021, there are more reasons why people love Linux than ever before. In this series, I'll share 21 different reasons to use Linux. Here are four open source tools for turning any device into a Linux server. Sometimes I detect a certain mystique around the idea of a server. Many people, should they have an image in their mind at all, think servers must be big, heavy, rack-mounted machines, carefully maintained by an overly deliberate sysadmin and a group of magical tinker gnomes. Other people envision servers as vaporous clouds that somehow power the internet.

In August 2020, Ansible issued its first release since the developers split the core functionality from the vast majority of its modules and plugins. A few basic Ansible modules remain part of core Ansible—modules for templating configuration files, managing services, and installing packages. All the other modules and plugins found their homes in dedicated Ansible collections. read more

My wife and I moved into a new home in October 2020. As soon as it started getting cold, we realized some shortcomings of the home's older heating system (including one heating zone that was always on). We had Nest thermostats in our previous home, and the current setup was not nearly as convenient. There are multiple thermostats in our house, and some had programmed heating schedules, others had different schedules, some had none at all. read more
