While the EXT4 changes and XFS alterations for the Linux 3.14 kernel weren't too exciting, the Btrfs file-system update was submitted today for Linux 3.14 and it's definitely exciting.

After the recent tests of AMD's Kaveri APU with DDR3-800MHz to DDR3-2133MHz Linux memory testing and following up with AMD Kaveri DDR3-2400MHz testing on Ubuntu Linux, many Phoronix readers followed up with a request of new memory testing done on the Intel side. In this article are benchmarks of a Core i5 Haswell CPU looking at the CPU and graphics performance impact with memory frequency scaling on Ubuntu 14.04 with the Linux 3.13 kernel.

Sweden-based Enea is known for its telecom and networking middleware based on the Enea OSEck RTOS, but it has flirted with Linux for years. Back in 2006, it began selling embedded Linux stacks based on MontaVista Linux for those customers who wanted to mix Linux and OSEck products in their product offerings. In 2011, the company introduced a Timesys-based Linux distro linked to NetLogic Microsystems processors. In recent years, it launched a full-fledged Enea Linux embedded distribution based on Yocto Project code.

The Joomla! community, inside and outside the company, is diverse and multi-cultural. It is made up of all sorts of people with two things in common: a love for Joomla! and a willingness to reach out and help others on the other side of the keyboard.

When you walk into the cavernous, old tire plant of Canal Place in Akron, Ohio, the last thing that you'd expect to find in this big building is such a "tiny" treasure. Unexpected though it may be, this is where Ken Burns and the TinyCircuits team has set up shop, and it's where they make tiny open source hardware treasures: miniaturized Arduino compatible circuits.

Intel’s Linux-friendly (Next Unit of Computing) mini-PCs are aimed at home theater applications, as well as other general-purpose mini-PC duties. Previous models have featured Intel Core processors, including 4th Gen. “Haswell” CPUs, but for the first time, Intel has launched a NUC Kit DN2820FYKH model based on the Celeron N2820. This 2.4GHz dual-core processor shares the same 22nm “Silvermont” architecture as the Atom E3800 (Bay Trail-I).

pax is one of the lesser known utilities in a typical Linux installation. That's too bad, because pax has a very good feature set, and its command-line options are easy to understand and remember. pax is an archiver, like tar(1), but it's also a better version of cp(1) in some ways, not least because you can use pax with SSH to copy sets of files over a network. Once you learn pax, you may wonder how you lived without it all these years.

After this weekend carrying out a 25-way open-source Linux graphics driver comparison featuring AMD Radeon, Intel HD Graphics, and NVIDIA GeForce hardware, the tables have now turned to look at nearly the same assortment of hardware but when using the high-performance, proprietary Linux graphics drivers. We've also upped the demanding OpenGL benchmarks used -- including the Source Engine -- as we see how the AMD and NVIDIA binary graphics drivers are doing to start 2014.

Yesterday I delivered some interesting results showing Freescale's i.MX6 quad-core ARM SoC outperforming one of the original Intel Atom SOCs, with both devices being from low-powered Linux-friendly CompuLab PCs. While the full review of the i.MX6-based CompuLab Utilite is still being written, here's some more preview benchmarks comparing the quad-core i.MX6 to the Atom Z530 to a NVIDIA Tegra 2 to a low-power Ivy Bridge CPU.

The Matrix MXE-5400 updates Adlink’s MXE-5300 model released in 2012, which ran on the “Sandy Bridge” generation of Intel Core i7/i5/i3 processors. Adlink skipped over the 3rd Generation “Ivy Bridge” core processors and went straight for Intel’s 4th Gen. “Haswell” line of Core CPUs, specifically targeting the quad-core, 2.4GHz Core i7-4700EQ. The company is also working on a Matrix MXC-2300 model that runs on an Intel Atom E3800 (Bay Trail-I) processor.

Michael Davies, a part of the Linux.conf.au (LCA) conference talk review committee, spent a session at this year's conference talking about how they review talk submissions and choose which ones to accept for this large Australian open source conference. While he spoke specifically about LCA, his tips are largely applicable to those interested in submitting a talk proposal to any conference. The LCA papers committee consists of experienced LCA attendees and volunteers who are both active in their communities and familiar with the conference. They try to keep a balance from year to year of fresh voices with experienced reviewers. The repeat reviewers help ensure that the conference maintains the same feel from year to year, so they use the previous year's papers committee with a few new members. They also consider the balance of the committee members.

Servers — whether used for testing or production — are primary targets for attackers. By taking the proper steps, you can turn a vulnerable box into a hardened server and help thwart outside attackers. Learn how to tighten Secure Shell (SSH) sessions, configure firewall rules, and set up intrusion detection to alert you to possible attacks on your GNU/Linux® server.

From its beginning, KDE has been a leader in innovation in free (libre) and open source software (FLOSS), but there is a threat to that leadership in one of the fastest growing areas of technology. The advantages of free and open development and use are clear for software; now closed and proprietary strategies have become standard in other kinds of technology. The need for technology freedom has moved from software to other more corporate-controllable areas—notably hardware and the Internet.

Sustainable open source projects are those that are capable of supporting themselves. Simply put, they are able to meet their ongoing costs. However, from the viewpoint of selection and procurement, sustainability also means that the project is capable of delivering improvements and fixing problems with its products in a timely manner, and that the project itself has a reasonable prospect of continuing into the future. Elsewhere on our site you can find articles describing some of the many formal approaches to evaluating open source software as part of the Software Sustainability Maturity Model.

Amazon is one of the most technically influential companies operating today – but you wouldn't know it, thanks to a dearth of published research papers and negligible code contributions to the open-source projects it relies on. This, according to multiple insiders, is becoming a problem. The corporation is described as a "black hole" because improvements and fixes for the open-source software it uses rarely see the light of day. And, we're told, that policy of secrecy comes right from the top – and it's driving talent into the arms of its rivals.

Back in 2006, Italian embedded Linux manufacturer Acme Systems shipped a penguin-shaped Tux Case for its original Fox single board computer (SBC). The new Arietta G25 computer-on-module (COM) is equipped with the same Atmel AT91SAM9G20 processor used by an updated Fox G20 SBC, as well as a newer 24-Euro Aria G25 COM that is more closely related to the Arietta G25 (see farther below). The Tux Case is still available, as well.

The cash-strapped OpenBSD Foundation has raised $100,000, potentially saving it from the brink of oblivion. The Foundation has had pledges of "around" $100,000 from individuals and organisations following its appeal to cover a $20,000 server electricity bill.

In December, the Italian government issued final rules implementing a change to procurement law that now requires all public administrations in the country to first consider re-used or free software before committing to proprietary licenses. Importantly, the new rules include an enforcement mechanism, which can, at least in theory, annul decisions that do not follow these procedures.

If you're looking around for 3D printers that are both inexpensive and open source friendly, the Printrbot Simple Kit will probably catch your attention. This Kit sells for close to $300, and for our team required a full-day of DIY assembly, though skilled makers might be able to put it together in four hours or so. Our team was made up of three PhDs and two R&D engineers, and it took us close to eight hours to complete the assembly, which of course included some philosophical and licensing discussions and a couple of trips to the hardware store. It was indeed a lot of fun!

In addition to the annual Embedded Linux Conference, Linux Kernel Summit, and LinuxCon events in North America and Europe, the LF’s 2014 events include a Linux Foundation Collaboration Summit, an Android Builders Summit, and an expanding series of events focused on networking, cloud services, virtualization, and other specialized technologies. This year’s LinuxCon and CloudOpen North America will be co-located with the Linux Kernel Summit, while LinuxCon and CloudOpen Europe will co-located with the Embedded Linux Conference, KVM Forum, and Linux Plumbers Conference.
