Announcing Rockstor 3.9.0

Filed under

Linux

We’ve just wrapped up a fun release cycle, and it’s my pleasure to announce Rockstor 3.9.0. Our community has been really active and we’ve prioritized nicely to improve on a few different areas. 5 contributors have come together for this release and besides working on new features and bug fixes, we made significant improvements to code quality. @phillxnet has made a big enhancement to the disk management subsystem. I’ve made large code quality improvement to backend Python stack. @MFlyer collaborated with me on that and took upon himself to do the same for all of Javascript stack. He made several ninja style contributions and helped fix many bugs. I’d say this is a nice release with some new stuff and a bunch of useful maintenance updates. Thanks to everyone that made this happen!

Hardware

WinSystems unveiled a rugged “PCM-C418” SBC with a dual-core, Vortex86DX3SoC, Fast and Gigabit Ethernet ports, SATA and CF storage, and PC/104 expansion.

The WinSystems PCM-C418 SBC offers a combination of PC/104 expansion, GbE and Fast Ethernet ports, shock and vibration resistance, and a Linux-friendly, x86-based Vortex86DX3 SoC — attributes shared by the Diamond Systems Helix and Adlink CM1-86DX3. Like the Helix, it also supports -40 to 85°C temperatures.

Blender - Your FOSS 3D Software

Filed under
Linux

If you are into game development, video editing, or 3D modeling as a professional or a hobby, then Blender is a tool you should definitely look at. Blender is a FOSS solution/alternate to many commercial tools that are available and it is able to strongly match most of these commercial tools. Blender is a cross-platform application which means you can not only run it on Linux but also on Windows and MacOS. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process. It supports the entirety of the 3D pipeline, anything from modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and game creation.

  • Performance analysis in Linux

    Dynamic profilers are tools to collect data statistics about applications while they are running, with minimal intrusion on the application being observed.

    The kind of data that can be collected by profilers varies deeply, depending on the requirements of the user. For instance, one may be interested in the amount of memory used by a specific application, or maybe the number of cycles the program executed, or even how long the CPU was stuck waiting for data to be fetched from the disks. All this information is valuable when tracking performance issues, allowing the programmer to identify bottlenecks in the code, or even to learn how to tune an application to a specific environment or workload.

    In fact, maximizing performance or even understanding what is slowing down your application is a real challenge on modern computer systems. A modern CPU carries so many hardware techniques to optimize performance for the most common usage case, that if an application doesn't intentionally exploit them, or worse, if it accidentally lies in the special uncommon case, it may end up experiencing terrible results without doing anything apparently wrong.

  • DevOps still very much a work in progress, survey suggests

    That's the key takeaway from a recent survey of 2,045 IT managers and professionals, released by Quali, an IT automation solutions provider. While most people in enterprises would say at this point that they have DevOps underway in some shape or form, achieving agility is another story.

    It's only a matter of time before every major cloud vendor offers a version of Kubernetes as a service. Now it’s IBM’s turn.

  • In The Virtualization Space, Containers Are Making A Move

    Wow has it been a whirlwind over the last ten years in the virtualization space. Where once Xen and then KVM sat on the pedestal, the baton has been passed to the projects revolved around containers. Names like Docker, Kubernetes and Mesos are most often mentioned. As is generally the case in the FLOSS arena, evolution is a constant. Therefore, if one is in the DevOps arena, it is time to familiarize yourself with containers if you have not already done so.

  • The DOE and NSA Construct Doomsday Scenario for American HPC

    One last point. The Chinese economy continues to expand faster than that of the US, and, depending on who you talk to, will reach the size of the US sometime between 2018 and 2028. Such an economy would be expected to field an HPC capability on par with that of the US. Furthermore, China and the US should both be able to maintain an indigenous and self-sustaining HPC capability for their own use, and it’s unreasonable to think either could prevent the other from doing so. In such a world, the US may no longer enjoy technological supremacy, but it can surely have the wherewithal to control its own future in HPC.

  • [Older] Getting Down To Bare Metal On The Cloud

    When you think of the public cloud, the tendency is to focus on the big ones, like Amazon Web Services, Microsoft Azure, or Google Cloud Platform. They’re massive, dominating the public cloud skyline with huge datacenters filled with thousands of highly virtualized servers, not to mention virtualized storage and networking. Capacity is divvied up among corporate customers that are increasingly looking to run and store their workloads on someone else’s infrastructure, hardware that they don’t have to set up, deploy, manage or maintain themselves.

  • Avoid complex infrastructure when building simple things

    For local development, go crazy. For real production use.. I think you should avoid this until you’re the size of business that someone else will do this for you. If this seems controversial do the math: include backing it up, patching it, keeping it highly available, the time spent not working on your differentiating features etc. There are plenty of datastore services available that will do all this for you and let you focus your limited time on your app, and they’re really very cheap when you consider the actual cost of running a production database. Write your app so that the cost of moving to your own database later if you need to is unlikely to be high. Managing a simple web app instead of managing a web app, a production database, a message queue etc is a big win.

Rugged, Linux-ready sandwich style SBC packs Skylake CPUs

Filed under
Linux

VersaLogic’s 125 x 85 x 37mm “Blackbird” offers Skylake CPUs, up to 32GB of DDR4, 3x mini-PCIe sockets, wide-range power, and MIL-STD-202G ruggedization.

VersaLogic calls its dual-layer Blackbird an Embedded Processing Unit (EPU). Like the other VersaLogic EPUs we’ve seen, such as the Atom-based Osprey EPU, the Blackbird is a three-layer sandwich consisting of a COM Express module in the middle, a same-sized I/O interface board on the top, and a heat spreader on the bottom. Compared to the Osprey, the Blackbird has a lot more real-world ports, making it more SBC-like rather than a COM with SBC-like characteristics. The Blackbird is “supplied fully assembled and tested, including heat plate, ready to install in a system,” says Versalogic.

Four Things a New Linux User Should Know

If you’re making the move from Windows or Mac (or even from Android or iOS), welcome to our world. These days, using Linux for doing everyday computer tasks isn’t that much different than using other operating systems — meaning the learning curve is only slight. In fact, my colleague Phil Shapiro works at a library that uses Linux on the computers its patrons use and says that hardly anyone even notices they’re not using Windows. It’s that easy. Read more
