Another day, another small-form-factor PC. This one, the pcDuinos3S, meets that fine line between budget-friendly and usable, being priced at $99 and able to run either Android or Linux, depending on your needs. We've got a rundown of its features after the jump.
The pcDuino3S is a case-toting alternative to the slightly cheaper and case-lacking pcDuino3, which is sold for $77. With the 3S model comes the same features, as well as a white box around the board that saves those without DIY inclinations some hassle.
GS4 unveiled an autonomous, Linux-based robot security guard called Bob, based on a MetraLabs “Scitos A5″ robot programmed by the University of Birmingham.
U.K.-based security firm GS4 Technology has launched a three week trial at its Gloucestershire headquarters of a robot called Bob that was designed by the University of Birmingham School of Computer Science. GS4 will evaluate Bob’s performance as a trainee security officer. Bob is part of a £7.2 million ($12.2 million) project called STRANDS, hosted by the University of Birmingham, with an aim of expanding the role of robots in the workplace.
As it's been a while since last delivering any "4K" resolution OpenGL benchmarks at Phoronix, out today -- now that we're done with our massive 60+ GPU open-source testing and 35-way proprietary driver comparison -- are benchmarks of several NVIDIA GeForce and AMD Radeon graphics cards when running an assortment of Linux games and other OpenGL tests at the 4K resolution.
Writing poems about the Linux kernel has been enlightening in more ways than one for software developer Morgan Phillips.
Over the past few months she's begun to teach herself how the Linux kernel works by studying text books, including Understanding the Linux Kernel, Unix Network Programming, and The Unix Programming Environment. But instead of taking notes, she weaves the new terminology and ideas she learns into poetry about system architecture and programming concepts. (See some examples, below, and on her Linux Poetry blog.)
Ivan Shapovalov is back on track with his Reiser4 file-system contributions.
Shapovalov has been working on Reiser4 support for TRIM/Discard on SSDs. It's been some weeks since the last revision but the fourth version of the patches are now out there for this common file-system feature of being able to discard blocks by informing the solid-state drive about blocks that are no longer in use by the file-system. Most mainline Linux file-systems already support SSD discard, which is generally exposed via the discard mount option -- which is also the case for Reiser4.
If you've been following along with our earlier articles on next-gen filesystems like btrfs and zfs, but wanted an easy way to get started without having to learn anything on the command line (or need an easy way to take advantage even though you're a Windows-only user), you're in luck. Today, we're going to look at two ready-to-rock ZFS-enabled network attached storage distributions: FreeNAS and NAS4Free.
A journey from Windows through doubt, frustration and despair to relief and a finally joy. This journey started on 31 May 2014 the day after the release of Linux Mint 17 “Qiana” Cinnamon and finished on the 17 June 2014. I worked on this continually for 8 or more hours a day over this time can’t work at the moment so I had time on my side.
HP Helion uses its own version of Linux based on the the open-source Debian Linux operating system at its core, which is a shift away from Ubuntu Linux, the Linux distribution previous iterations of HP's cloud efforts had been using.
High-performance computing (HPC) for the past ten years has been dominated by thousands of Linux servers connected by a uniform networking infrastructure. The defining theme for an HPC cluster lies in the uniformity of the cluster. This uniformity is most important at the application level: communication between all systems in the cluster must be the same, the hardware must be the same, and the operating system must be the same. Any differences in any of these features must be presented as a choice to the user. The uniformity and consistency of running software on an HPC cluster is of utmost importance and separates HPC clusters from other Linux clusters.
While the open source community is filled with some of the most talented minds in the world, fresh perspectives from the next generation of developers is essential to the continued pioneering spirit of open source projects. Such an injection of youthful enthusiasm lends new creative blood to the open source community, allowing projects to stay cutting edge and in keeping with current trends.
To that end, the seeds of progress are often planted in the summertime as enterprising college students participate in the annual Google Summer of Code. The global program offers student developers stipends to write code for various free, open source software projects.
Both OS X and Windows 8 are fairly closed operating systems, merely allowing coders to run commands and pulling a veil over the internals of the software powering the machine. The same goes for hardware: all-in-ones, laptops, and tablets alike aren't easy for curious types to take apart and see what's inside.
It's a situation that's creating a generation of individuals that merely use their PCs, instead of using them to create.
A small British company with an Israeli founder, Yonatan Raz-Fridman, and strong Israeli ties, is trying to change that. Kano is offering a 'do it yourself' computer kit based on the popular Raspberry Pi $35 Linux PC, and designed to encourage users of all ages to explore and create with technology.
Building upon the major blk-mq work for the multi-queue block layer, the SCSI multi-queue code is now in good shape according to its developers, is delivering very promising performance results, and should be merged into the Linux 3.17 kernel cycle.
SCSI-mq is too late for Linux 3.16, but it was already anticipated it would come with Linux 3.17. SCSI-mq is about plugging the SCSI kernel code to take advantage of the multi-queue block layer code. "This patch adds support for an alternate I/O path in the scsi midlayer which uses the blk-mq infrastructure instead of the legacy request code. Use of blk-mq is fully transparent to drivers." The multi-queue block layer was first introduced in Linux 3.14 and is now fairly complete with Linux 3.16. The multi-queue block layer allows balancing I/O workload across multiple CPU cores and supports multiple hardware queues along with other performance optimizations.
Linux users need Wine to run applications from the Windows platform, but the bulk of apps accessed in this way is actually quite old. Sure enough, it's possible to run newer software as well, but most users need Wine for much older stuff.
One of the latest updates for Linux kernel 3.14.x brought some modifications and users found out that they couldn’t run Wine configured as Windows 9x, which is actually an important option.
ALSA 1.0.28 features various small updates to the alsa-oss and alsa-tools components, adds new sound firmware files for the Cirrus Logic CS46xx, boasts small changes to alsa-plugins, and as usual most of the work happened within the alsa-lib and alsa-utils components. Within the ALSA library for 1.0.28 are many API updates while within the ALSA utilities area are many updates to ALSA Control and Speaker Test.
