Not only has the DNS become the standard but lazy way to serve out domain-related information for other purposes and protocols, DNSSEC is now relatively easy to implement.

For the past year, I've been teaching students how to build and program robots using the LEGO Mindstorms EV3 platform. From the outset, I wanted to find a way to use Scratch and other open source programming languages to extend the capabilities of the platform. That search led me to BrickPi, a Raspberry Pi add-on board from Dexter Industries that easily interfaces with Mindstorms sensors and motors. read more

The Ibus typing booster is a predictive text input method. The project goal is to empower existing keyboard layouts with predictions to allow users to boost their typing speed without compromising on data accuracy. This project started in 2010 with... Continue Reading →

I sat down at the Open Source Leadership Summit to record a podcast with Mikeal Rogers, who heads the Node.js Foundation, a collaborative project under the Linux Foundation. read more

In this tutorial, we will be going through the installation steps for Elasticsearch followed by the installation of Kibana and then we will use Kibana to store and retrieve data. Elasticsearch is a production ready search engine written in java and is extremely powerful. It can be used as a standalone search engine for the web or as a search engine for e-commerce web applications.

Three years ago, the Heartbleed vulnerability in the OpenSSL cryptographic library sent the software industry and companies around the world into a panic. Software developers didn't know enough about the open source components used in their own products to understand whether their software was vulnerable - and customers using that software didn't know either.

When I first started considering container use in production environments, a question came to mind: When a container may exist across a cluster of servers, how do I get others (people, or applications) to connect to it reliably, no matter where it is in the cluster?

Aries’ “M6UL” COM expands on an i.MX6 UltraLite SoC with 4GB eMMC, dual Ethernet ports, and dual CAN ports, as well as DRM ID, encryption, and secure boot. Germany-based Aries Embedded has announced a “M6UL” computer-on-module as a drop-in replacement for its earlier i.MX28-based M28 COM. The new device keeps the SODIMM-style form factor, but advances to NXP’s i.MX6 UltraLite (UL) SoC.

The tBOX324-894-FL computer is designed for train management, truck fleet management, transportation controller, data transfer, and security surveillance, as well as infotainment controllers in vehicle, railway, and marine markets, […]

There comes a time in your life when you have to share one or more files with someone, whether that someone is a friend, a family member, a colleague or collaborator, or a client. Many people stay true to their open source convictions by doing the job using applications like ownCloud, Nextcloud, or SparkleShare. read more

GNU Screen (or just Screen) is a useful and versatile, but somewhat under-appreciated utility that, as part of the GNU project, is included or available in nearly every Linux or UNIX distribution. Screen is a terminal multiplexer, similar to what you would find in a window manager. It is an especially helpful utility if you are restricted to working on a computer or a virtual machine either over an SSH link or through a terminal session on the console. read more

If you think about it, isn't the Internet just a giant mesh network? If we deviate slightly from the standard definition that requires that all nodes to assist in data distribution, the answer is a resounding yes. However, traditional network technologies and the vendor-provided hardware required to run them is often far too expensive to deploy without deep pockets. Open source software aims to solve these problems and enable network connectivity to marginalized groups all around the world. read more

In this tutorial, I will guide you step-by-step to use docker-compose to create a LEMP Stack environment (LEMP = Linux - Nginx - MySQL - PHP). We will run all components in different docker containers, we set up a Nginx container, PHP container, PHPMyAdmin container, and a MySQL/MariaDB container.

You'll find that the quickest way to build components of an IoT ecosystem is to use embedded Linux, whether you're augmenting existing devices or designing a new device or system from the beginning. Embedded Linux shares the same source code base as desktop Linux, but it is coupled with different user interface tools and other high-level components.

If you are installing Linux on your IBM® Power® System S822LC server, then the instructions in this article can help you to start and run your system. These instructions are specific to installing CentOS 7 on an IBM Power System S822LC server for high-performance computing (HPC).

Today’s software supply chain is fundamentally different than it was only a few years ago, and open source programs at large enterprises are helping to drive that trend. According to Sonatype’s 2016 State of the Software Supply Chain enterprises are both turning to existing open source projects to decrease the amount of code they have to write, and increasingly creating their own open source tools.

More than 1 million websites running the WordPress content management system may be vulnerable to hacks that allow visitors to snatch password data and secret keys out of databases, at least under certain conditions.

In this blog series, we’re laying out a set of baseline recommendations for Linux workstation security to help systems administrators avoid most glaring security errors without introducing too much inconvenience. Last week, we covered security considerations for choosing your hardware.

NComputing’s RPi 3-based “RX300” thin client can be used as client for its vSpace Pro 10 virtualization platform, as well as in standalone Raspbian mode. NComputing has been delivering Linux- and Windows-compatible virtual thin clients for over a decade, with a special focus on the education market and a secondary focus on small businesses.
