Servers connected to the internet are seeing a constant level of attacks and scans all day. While a firewall and regular system updates are a good first defense to keep the system safe, you should also check regularly that no attacker got in. The tools described in this tutorial are made for these sanity checks, they scan for malware, viruses and rootkits.

This is my first article for a new column here on Opensource.com about music from an open point of view. Some things I won't be doing: I won't be concentrating solely on music released under an open license. I won't be writing (much) about making one's own music. I won't be writing (much) about music theory or professional matters, or probably really very much of anything of interest to professional musicians. read more

I like to think of every day on Opensource.com as I love Free Software Day, but we couldn't miss celebrating the official I love Free Software Day 2016, too. Granted, the official day to say "thank you" is on February 14th, so we're showing our love a little early to make sure you don't miss it. read more

Qualcomm unveiled a Snapdragon Wear 2100 chip for wearables, plus a 14nm octacore Snapdragon 625, and 28nm Snapdragon 435 and 425 SoCs. Only a few years ago, announcements of new Qualcomm Snapdragon announcements were somewhat tangential to embedded Linux and Android developers. Increasingly, however, Snapdragons are appearing on embedded SBCs and COMs and finding their way […]

I love video game emulation. My favorite games were produced in the 1980s and 1990s, so if I want to play them, I almost always have to emulate the old systems. There is usually a legal concern about ROM files for games, even if you own the original cartridges, so I'm not going to tell you where to find ROMs to download or anything like that.

If there is one word that often percolates conversations hailing the benefits of open source, it is choice. We often celebrate many of the 800+ Linux distributions, the countless desktops, applications, frameworks, and more. Choice, it would seem, is a good thing. Interestingly, choice is also an emotive thing. read more

LiteSpeed web server is a popular choice for replacing an Apache web server. Its features include an optimization of the web content and content delivery which maximizes the download speed and combines better performance with a smaller memory footprint. Being compatible with Apache features is also an added benefit, which helps to reduce downtime during migration from Apache to LiteSpeed. This tutorial shows the installation on a CentOS 7 server.

As a programmer I sort and collect a lot of research, and my problem has always been finding a place to store it all. I had Jekyll in mind for a while, but it always seemed so daunting to get into. After a few days of configuration, I was able to create a Jekyll workflow that enables me to do a few things: read more

In Soviet Russia, computer uninstalls you! The Russian government says it is looking to dump Microsoft and adopt Linux as the operating system for agency PCs.…

At the same time, Canonical is finally delivering on its promise to deliver one codebase for all devices. The upshot is you'll be able to use the first Ubuntu tablet, the Aquaris M10 Ubuntu Edition tablet, as a PC as well as a tablet.

Most people who use computers understand at least the basics of how they work. There's the hardware, that actually does the computing; an operating system, that sits on top and serves as an interface between the computer hardware and the programs run by users, and then the actual applications we use which sit on top of that. Sometimes, though, it's a little more complex than that simple abstraction. read more

Mentor Graphics has updated Mentor Embedded Linux (MEL) with Yocto Project 2.0 code, SMACK security, and support for CANopen, BACNet, and 6LoWPAN. Mentor Graphics has spun a more secure and industrial IoT-ready version of its commercial Mentor Embedded Linux (MEL) distribution and development platform that moves up to a modern Linux codebase built around Yocto […]

I’ve been going to FOSS (free and open source) conferences since 2006. My first open source conference was FreedomHEC in Seattle, a little 30-person conference for Linux users to protest Microsoft’s WinHEC. My next open source conference was OSCON, which had over a thousand attendees. They were both very different conferences, and as a college student, I really didn’t know what to expect. Going to your first open source conference can be intimidating, so I’ve complied ten tips for people who are new to the conference circuit.

Elesar’s “Titanium” is a feature-rich board based on TI’s AM5728 SoC, featuring dual Cortex-A15, dual DSP, and dual Cortex-M4 cores, plus a dual-core GPU. It’s not too often that a workalike board ships before the original, but that appears to be the case for UK-based Elesar’s Titanium development board. The Titanium is not really a […]
