Oracle Still Working On DTrace For Linux In 2018

Monday 12th of February 2018 01:08:55 PM
A decade ago Linux users were clamoring for Sun Microsystems to bring Solaris' DTrace and ZFS to Linux. While there are still petitions for Oracle to more liberally license ZFS so it could see mainline Linux support, it's been years since hearing much interest in DTrace for Linux. Over time other dynamic tracing implementations have come about and improved in comparison to DTrace, but for those still wanting this dynamic tracing framework that originated at Sun Microsystems, Oracle remains working on the Linux port...

  • State of Linux Containers
    In this video from the Stanford HPC Conference, Christian Kniep from Docker Inc. presents: State of Containers. “This talk will recap the history of and what constitutes Linux Containers, before laying out how the technology is employed by various engines and what problems these engines have to solve. Afterward, Christian will elaborate on why the advent of standards for images and runtimes moved the discussion from building and distributing containers to orchestrating containerized applications at scale. In conclusion, attendees will get an update on what problems still hinder the adoption of containers for distributed high performance workloads and how Docker is addressing these issues.”
  • ONS 2018: Networking Reimagined
    For the past seven years, Open Networking Summit (ONS) has brought together the networking industry’s ecosystem of network operators, vendors, open source projects, leading researchers, and investors to discuss the latest SDN and NFV developments that will shape the future of the networking industry. With this year’s event, taking place March 26-29, 2018 in Los Angeles, ONS will evolve its approach as the premier open source networking event. We’re excited to share three new aspects of this year’s ONS that you won’t want to miss:
  • AT&T contributes code to Linux open source edge computing project
    The Linux Foundation recently announced a new project, dubbed Akraino, to develop an open source software stack capable of supporting high-availability cloud services for edge computing systems and applications. To kick off the project, AT&T will contribute code made for carrier-scale edge computing applications running in virtual machines and containers.
  • AT&T Brings Akraino Networking Project to Edge of the Linux Foundation
    The Linux Foundation has been particularly busy in 2018 thus far consolidating its existing networking project under a single umbrella, known as LF Networking. That umbrella might need to get a bit larger, as on Feb. 20 the Linux Foundation announced the new Akraino project, with code coming initially from AT&T.
  • FreeOffice 2016 – An Efficient Alternative to Microsoft Office
    FreeOffice 2016 is the latest version of the Office software from SoftMaker. In fact, you wouldn’t be wrong if you called it the free version of SoftMaker Office 2018 seeing as it features the same suite of applications.
  • Stellaris 2.0 'Cherryh' patch & Stellaris: Apocalypse expansion released, over 1.5 million copies sold
    Stellaris: Apocalypse [Steam], the latest expansion for the grand space strategy game from Paradox Development Studio is out. The big 2.0 'Cherryh' patch is also now available. Paradox has also announced today, that Stellaris has officially passed 1.5 million copies sold making it one of their most popular games ever made. I'm not surprised by this, as I consider Stellaris their most accessible game.
  • Action-packed platformer with local and online co-op 'Vagante' has left Early Access
    After being in Early Access for quite some time, the action-packed platformer 'Vagante' [Steam, Official Site] has now officially left Early Access.

  • Getting Debian booting on a Lenovo Yoga 720
    I recently got a new work laptop, a 13” Yoga 720. It proved difficult to install Debian on; pressing F12 would get a boot menu allowing me to select a USB stick I have EFI GRUB on, but after GRUB loaded the kernel and the initrd it would just sit there never outputting anything else that indicated the kernel was even starting. I found instructions about Ubuntu 17.10 which helped but weren’t the complete picture. What seems to be the situation is that the kernel won’t happily boot if “Legacy Support” is not enabled - enabling this (and still booting as EFI) results in a happier experience.
  • Dell PowerEdge T30
    I just did a Debian install on a Dell PowerEdge T30 for a client. The Dell web site is a bit broken at the moment, it didn’t list the price of that server or give useful specs when I was ordering it. I was under the impression that the server was limited to 8G of RAM, that’s unusually small but it wouldn’t be the first time a vendor crippled a low end model to drive sales of more expensive systems. It turned out that the T30 model I got has 4*DDR4 sockets with only one used for an 8G DIMM. It apparently can handle up to 64G of RAM.
  • Quad-Ethernet SBC and controller tap new Renesas RZ/N1D SoC
    Emtrion’s Linux-ready “SBC-RZN1D” SBC, which will soon power a “Flex2COM” controller, features a Renesas dual-core -A7 RZ/N1D SoC and 4x LAN ports, and is designed for multi-protocol fieldbus communications. Emtrion, which recently announced its emCON-RZ/G1H module based on an octa-core Renesas RZ/G1H SoC, has unveiled a Renesas based, quad-LAN port SBC-RZN1D SBC focused on industrial communication. The SBC-RZN1D taps the Renesas RZ/N1D (R9006G032), one of a new line of RZ/N1D SoCs launched last year by Renesas for industrial multi-protocol communications. Renesas recently collaborated with Avnet to ship its own dual-Ethernet Renesas RZ/N1D Solution Kit (see farther below).
  • Postage-Stamp Linux
    There was a time when big operating systems ran on big iron. IBM, Data General, Burroughs, DEC, and other computer makers built big machines with big, blinking lights, and big price tags. They ran grown-up software and they supported multiuser operating systems. If you wanted a toy, you built a microcomputer. If you wanted a real machine for serious work, you bought a mainframe. Maybe a minicomputer, if it were for lesser tasks.
  • Most Popular Android Versions In February 2018 (Always Updated List)
    Android is the most used operating system on the planet. In fact, it’s almost omnipresent in the mobile ecosystem. Even the Android versions, like Nougat, Marshmallow, Lollipop, etc. have been able to build their individual fan following.

Red Hat and Fedora: David Egts, Radcom, Google Summer of Code 2018, FOSS Wave

  • Red Hat’s David Egts: Microservices Tech Could Help Simplify App Deployment
    David Egts, chief technologist for Red Hat’s public sector, told MeriTalk in an interview published Wednesday that the microservices technology works to help the developer split complex, large applications into small components and share them with other members of the DevOps team.
  • Radcom partners with Red Hat for NFV management
    Radcom announced it is collaborating with Red Hat to provide operators with a fully virtualized network visibility solution running on Red Hat OpenStack Platform. As operators transition to NFV, a critical first step is gaining end-to-end network visibility. This collaboration enables operators to attain cloud-native network visibility without the hassle of building their own private cloud infrastructure, the vendor said. Once the operator's transition to NFV matures, integration efforts with the NFV and MANO infrastructure can be simplified.

  • Justin W. Flory: Humanitarian open source work: My internship at UNICEF
    In December, I received the happy news of an offer for a internship position at UNICEF in the Office of Innovation. The Office of Innovation drives rapid technological innovation by rapid prototyping of new ideas and building full-stack products to make a positive impact in the lives of children. This is a simple answer, but a more detailed description is on our website. My internship at UNICEF is unique: I support open source community engagement and research as my primary task for the MagicBox project. For years, I’ve done this in open source communities in my free time (namely SpigotMC and Fedora), but never in a professional role. As I navigate my way through this exciting opportunity, I plan to document some of the experience as I go through blogging. My intent is that my observations and notes will be useful to someone else in the humanitarian open source space (or maybe to a future me).
  • Fedora participating in Google Summer of Code 2018
    GSoC is a summer program aiming to bring more student developers into open source software development. It enables students to spend their summer break working with open source organizations on projects proposed by participating organizations and supported by mentors.
  • FOSS Wave with Fedora at KGISL, Coimbatore
    Recently, I was invited by Prem to NASSCOM to give a brief talk on FOSS and Technology as part of the FOSS Wave community. Prem is doing a great job there by putting his effort in helping students from Tier2 and Tier3 cities. Around twenty enthusiastic students were selected and invited to Bengaluru to take part in such events. Mine was one of them. I conducted a GitHub session after Intro to FOSS and a brief intro about Fedora Project.

  • 3 reasons to say 'no' in DevOps
    DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority. Instead of saying no, it may be helpful to take a hint from improv comedy and say, "Yes, and..." or "Yes, but...". This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.
  • 5 rules for having genuine community relationships
    As I wrote in the first article of this three-part series on the power and importance of communities, building a community of passionate and committed members is difficult. When we launched the NethServer community, we realized early that to play the open source game, we needed to follow the open source rules. No shortcuts. We realized we had to convert the company in an open organization and start to work out in the open.

  • Rust Typestates
    A long time ago, the Rust language was a language with typestate. Officially, typestates were dropped long before Rust 1.0. In this entry, I’ll get you in on the worst kept secret of the Rust community: Rust still has typestates.
  • It's Time To Do CMake Right
    Not so long ago I got the task of rethinking our build system. The idea was to evaluate existing components, dependencies, but most importantly, to establish a superior design by making use of modern CMake features and paradigms. Most people I know would have avoided such enterprise at all costs, but there is something about writing find modules that makes my brain release endorphins. I thought I was up for an amusing ride. Boy was I wrong.

OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

  • OpenBSD Gets Mitigated For Meltdown CPU Vulnerability
    A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.
  • Meltdown fix committed by guenther@

    Meltdown mitigation is coming to OpenBSD. Philip Guenther (guenther@) has just committed a diff that implements a new mitigation technique to OpenBSD: Separation of page tables for kernel and userland. This fixes the Meltdown problems that affect most CPUs from Intel. Both Philip and Mike Larkin (mlarkin@) spent a lot of time implementing this solution, talking to various people from other projects on best approaches.

    In the commit message, Philip briefly describes the implementation [...]
