In recent years, hardware virtualization has become commonplace in the computing industry and more available to end users. The idea behind it is a noble one. Why invest in allocating more server hardware and not utilize it to its full potential, when instead you can consolidate it all onto one or a few servers and share their resources?

iWave’s rugged, Linux-friendly, 95 x 75mm “Arria 10 SoC Module” expands upon the dual-core, ARM/FPGA SoC from Altera with DDR4 and 24 transceivers. The iWave Systems Arria 10 SoC Module builds upon Intel/Altera’s Arria 10 SX SoC, a faster, newer sibling to the Cyclone V SX, which iWave tapped for its Qseven based iW-RainboW-G17M-Q7 COM […]

Last Friday's massive DDoS that exploited online cameras and DVRs was simple to pull off -- and a new chapter in online attacks.

EMS computers in Guilford County, NC were exposed for an unknown length of time, because the server managing system updates was publicly available on the internet. The problem was discovered earlier this month by a researcher scanning the internet for Rsync servers.

Dozens of Opensource.com writers, moderators, and interviewees will converge in Raleigh, North Carolina this week at All Things Open. We've rounded up a list of their talks to help you track them down and meet them in person. Also be sure to stop by the Opensource.com booth to meet our editors and grab swag.

As a quick introduction, Kubernetes is "an open-source system for automating deployment, scaling and management of containerized applications" often referred to as a container orchestrator.

“Dirty COW” is a serious Linux kernel vulnerability that was recently discovered to have been lurking in the code for more than nine years. It is pretty much guaranteed that if you’re using any version of Linux or Android released in the past decade, you’re vulnerable. But what is this vulnerability, exactly, and how does it work?

While looking at the this year's All Things Open event schedule, a talk on wearables and open hardware caught my eye: The world of the blinky flashy. Naturally, I dug deeper to learn what it was all about. Though Gina Likins and Jen Krieger of Red Hat would like to leave a few surprises for the lucky folks who attend their talk, they told me they can promise at least the following: read more

This tutorial shows how to install an Ubuntu 16.10 (Yakkety Yak) server (with Apache2, BIND, Dovecot) for the installation of ISPConfig 3.1, and how to install ISPConfig. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers the installation of Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).

Well, here we go again with yet another new technology with a name that doesn't tell us much about what it is: Hyperledger. Hyperledger is related to Bitcoin, Ethereum, and blockchains... but, what are these things? They sound like science fiction: I have plenty of Bitcoins, so let's go splurge on a nice evening at the Ethereum.

Developers, distributors, and users of Free and Open Source Software (FOSS) often face a host of legal issues which they need to keep in mind. Although areas of law such as copyright, trademark, and patents are frequently discussed, these are not the only legal concerns for FOSS. One area that often escapes notice is export controls. It may come as a surprise that sharing software that performs or uses cryptographic functions on a public website could be a violation of U.S. export control law. read more

There are various things that make up an operating system. In any operating system, one of the most critical parts is powering on the machine. During this process, the computer will execute a small program in read-only memory (ROM) to... Continue Reading →

Since the first of the month, I've heard colleagues and others report each of the 10 security variants to Murphy's Law listed below. Murphy is not only alive but has been reincarnated.

Open source depends on a sustainable community to develop code rapidly, debug code effectively, and build out new features. Because community involvement is voluntary, people's skills, levels of involvement, and time commitments can vary. Given the variable nature of these factors, along with the fact that open source often relies on a philosophy of "release early, release often," quality assurance can be become challenging. read more

The great promise of a global open source software project like OpenStack is that it can bring together the best and the brightest from all around the world to together create something far greater than any one person, company, or nation could do on its own.

This article describes the general installation and tuning of EnterpriseDB Postgres Advanced Server database on IBM Power Systems servers running Linux. IBM Power servers offer significant advantages compared to similar configurations of Intel Xeon processor-based systems (Broadwell).

At the OpenStack summit taking place this month in Barcelona, Ildikó Váncsa will be speaking on metrics in her talk Metrics: Friends or Enemies?

Renesas has launched two Linux-ready R-Car starter kits optimized for AGL and GENIVI: an R-Car H3 based “Premier” and a “Pro” with a lower-end M3 SoC. Later this month, Renesas will begin selling two third-generation starter kits for its 64-bit ARM-based R-Car automotive SoCs. The kits are designed for ADAS, infotainment, reconfigurable digital clusters, and […]
