  • Docker as a High-Performance Enabler for Cloud Storage

    The container-based service Docker is gaining massive momentum in the industry, and for many good reasons. The current appeal of Docker stems from issues associated with running VMs, namely that each one has to be provided with virtualized memory and storage resources. Containers make it far easier to run enterprise-grade services and address concerns for data portability, scaling, processing, performance, extensibility and latency.

  • Is Docker ditching Ubuntu Linux? Confusion reigns

    Docker has long relied on Ubuntu Linux as the default host environment for Docker apps, but comments from the company's CTO recently suggest that might not be the case much longer.

    "We have hired Natanael Copa, the awesome creator of Alpine Linux, and are in the process of switching the Docker official image library from Ubuntu to Alpine," a user named shykes wrote in a Hacker News thread 10 days ago.

Rosa Is a Real Powerhouse

Filed under
Linux
Reviews

The Rosa Desktop Fresh R series is one of the most impressive and productive Linux releases I have seen in quite some time. Its performance is top notch.

It gets high marks in all the right places: Installation is flawless, the KDE integration is innovative, and the software is reliable.

KDE is one of the most complex desktop environments, so potential users who are less familiar with the Linux OS should approach the default KDE release with the idea that it is a great computing platform but might not be what they need. Rosa developers offer enough options to meet the skill levels and needs of all user classes.

  • Unikernels, Docker, and Why You Should Care

    Docker's recent acquisition of Unikernel Systems has sent pulses racing in the microservice world. At the same time, many people have no clue what to make of it, so here's a quick explanation of why this move is a good thing.

    Although you may not be involved in building or maintaining microservice-based software, you certainly use it. Many popular Web sites and services are powered by microservices, such as Netflix, eBay and PayPal. Microservice architectures lend themselves to cloud computing and "scale on demand", so you're sure to see more of it in the future.

  • Now You Can Use uTorrent Without Ads, Thanks To New Subscription Model
    In the past, the parent company Bittorrent Inc. has relied on an ad-based revenue model to keep uTorrent up and running, but now they have realized the need for a premium experience for the users by charging a nominal amount. Until now, bundled software that hides inside the uTorrent installation package has only consumed space on your computer. The development team is well aware of this issue and that’s why they have come up with the ad-free uTorrent.

Kernel Space: Linux, Graphics

  • Linux kernel bug delivers corrupt TCP/IP data to Mesos, Kubernetes, Docker containers
    The Linux Kernel has a bug that causes containers that use veth devices for network routing (such as Docker on IPv6, Kubernetes, Google Container Engine, and Mesos) to not check TCP checksums. This results in applications incorrectly receiving corrupt data in a number of situations, such as with bad networking hardware. The bug dates back at least three years and is present in kernels as far back as we’ve tested. Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical). If you use containers in your setup, I recommend you apply this patch or deploy a kernel with this patch when it becomes available. Note: Docker’s default NAT networking is not affected and, in practice, Google Container Engine is likely protected from hardware errors by its virtualized network.
  • Performance problems
    Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things noticeably faster. The code got merged in v4.0 and that was that, I kept on kicking a few more ideas for optimizations in this area around but that was that until the past month.
  • Compute Shader Code Begins Landing For Gallium3D
    Samuel Pitoiset began pushing his Gallium3D Mesa state tracker changes this morning for supporting compute shaders via the GL_ARB_compute_shader extension. Before getting too excited, the hardware drivers haven't yet implemented the support. It was back in December that core Mesa received its treatment for compute shader support and came with Intel's i965 driver implementing CS.
  • Libav Finally Lands VDPAU Support For Accelerated HEVC Decoding
    While FFmpeg has offered hardware-accelerated HEVC decoding using NVIDIA's VDPAU API since last summer, this support for the FFmpeg-forked libav landed just today. In June was when FFmpeg added support to its libavcodec for handling HEVC/H.265 video decoding via NVIDIA's Video Decode and Presentation API for Unix interface. Around that same time, developer Philip Langdale who had done the FFmpeg patch, also submitted the patch for Libav for decoding HEVC content through VDPAU where supported.

Unixstickers, Linux goes to Washington, Why Linux?

  • Unixstickers sent me a package!
    There's an old, popular saying, beware geeks bearing gifts. But in this case, I was pleased to see an email in my inbox, from unixstickers.com, asking me if I was interested in reviewing their products. I said ye, and a quick few days later, there was a surprise courier-delivered envelope waiting for me in the post. Coincidentally - or not - the whole thing happened close enough to the 2015 end-of-the-year holidays to classify as poetic justice. On a slightly more serious note, Unixstickers is a company shipping T-shirts, hoodies, mugs, posters, pins, and stickers to UNIX and Linux aficionados worldwide. Having been identified one and acquired on the company's PR radar, I am now doing a first-of-a-kind Dedoimedo non-technical technical review of merchandise related to our favorite software. So not sure how it's gonna work out, but let's see.
  • Linux goes to Washington: How the White House/Linux Foundation collaboration will work

  • Why Linux?
    Linux may inspire you to think of coders hunched over their desks (that are littered with Mountain Dew cans) while looking at lines of codes, faintly lit by the yellow glow of old CRT monitors. Maybe Linux sounds like some kind of a wild cat and you have never heard the term before. Maybe you have use it every day. It is an operating system loved by a few and misrepresented to many.
