  • OCI Update: v1.0.1 Release and New Maintainer

    The OCI community continues to be hard at work, having just issued the first update to OCI v.1.0, after five months of focusing on stability. OCI 1.0.1 contains updates to both the image format and runtime specifications.

    We’re still growing and expanding, with even more collaboration since the launch of v 1.0. For example, we are now up to over 5,000 commits from 184 authors across 42 different organizations. Organizations like AWS, Docker, Cloud Foundry, CoreOS, Intel, Mesosphere, Oracle, Red Hat and Kubernetes have already taken advantage of the OCI v1.0 specifications, and with v1.0.1 now available, the industry is on the precipice of true portability and standardization. We had a strong showing on site at recent industry events, at both DockerCon Europe in Copenhagen and Open Source Summit Europe in Prague.

  • How enterprise IT uses Kubernetes to tame container complexity

    Running a few standalone containers for development purposes won’t rob your IT team of time or patience: A standards-based container runtime by itself will do the job. But once you scale to a production environment and multiple applications spanning many containers, it’s clear that you need a way to coordinate those containers to deliver the individual services. As containers accumulate, complexity grows. Eventually, you need to take a step back and group containers along with the coordinated services they need, such as networking, security, and telemetry.

    That’s why technologies like the open source Kubernetes project are such a big part of the container scene.

  • ARM emulator in a VM? Yup, done. Ready to roll, no config required

    Hacking low-level code on ARM processors just became a little easier after a researcher who operates under the name Azeria Labs put together virtual machines that emulate common hardware.

  • AMD Rolls Out ROCm 1.7 Platform For Supercomputing 17

    AMD has unveiled the Radeon Open Compute platform (ROCm) 1.7 release as part of their wares at this week's Supercomputing 17 (SC17) conference in Denver.

    The ROCm 1.7 update introduces multi-GPU support for "the latest Radeon GPU hardware" (presumably referring to Vega) while also supporting TensorFlow and Caffe via AMD's MIOpen libraries.

  • Red Hat introduces Arm server support for Red Hat Enterprise Linux
  • Red Hat Enterprise Linux for ARM64
  • Red Hat Enterprise Linux for ARM Hits General Availability

    Red Hat now considers their ARM support on Red Hat Enterprise Linux (RHEL7) to be supported under general availability "GA" terms.

  • Orange and Red Hat push open source NFVi development

    At the OpenStack Summit 2017, operator Orange has joined forces with equally colourful open-source software vendor Red Hat to promote NFVi innovation.

    Sadly the two companies have missed a trick by declining to name their mutual endeavour Orange Hat, but we mustn’t let that detract from the underlying cleverness. Orange seems to reckon network functions virtualization infrastructure is best done in the open-source environment and Red Hat unsurprisingly agrees.

  • China Pulls Ahead of U.S. in Latest TOP500 List

    The fiftieth TOP500 list of the fastest supercomputers in the world has China overtaking the US in the total number of ranked systems by a margin of 202 to 143. It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the US presence shrinking to its lowest level since the list’s inception 25 years ago.

GitLab Web IDE

  • GitLab Web IDE Goes GA and Open-Source in GitLab 10.7
    GitLab Web IDE, aimed to simplify the workflow of accepting merge requests, is generally available in GitLab 10.7, along with other features aimed to improve C++ and Go code security and improve Kubernets integration. The GitLab Web IDE was initially released as a beta in GitLab 10.4 Ultimate with the goal of streamlining the workflow to contribute small fixes and to resolve merge requests without requiring the developer to stash their changes and switch to a new branch locally, then back. This could be of particular interest to developers who have a significant number of PRs to review, as well as to developers starting their journey with Git.
  • GitLab open sources its Web IDE
    GitLab has announced its Web IDE is now generally available and open sourced as part of the GitLab 10.7 release. The Web IDE was first introduced in GitLab Ultimate 10.4. It is designed to enable developers to change multiple files, preview Markdown, review changes and commit directly within a browser. “At GitLab, we want everyone to be able to contribute, whether you are working on your first commit and getting familiar with git, or an experienced developer reviewing a stack of changes. Setting up a local development environment, or needing to stash changes and switch branches locally, can add friction to the development process,” Joshua Lambert, senior product manager of monitoring and distribution at GitLab, wrote in a post.

Record Terminal Activity For Ubuntu 16.04 LTS Server

At times system administrators and developers need to use many, complex and lengthy commands in order to perform a critical task. Most of the users will copy those commands and output generated by those respective commands in a text file for review or future reference. Of course, “history” feature of the shell will help you in getting the list of commands used in the past but it won’t help in getting the output generated for those commands. Read

Linux Kernel Maintainer Statistics

As part of preparing my last two talks at LCA on the kernel community, “Burning Down the Castle” and “Maintainers Don’t Scale”, I have looked into how the Kernel’s maintainer structure can be measured. One very interesting approach is looking at the pull request flows, for example done in the LWN article “How 4.4’s patches got to the mainline”. Note that in the linux kernel process, pull requests are only used to submit development from entire subsystems, not individual contributions. What I’m trying to work out here isn’t so much the overall patch flow, but focusing on how maintainers work, and how that’s different in different subsystems. Read more

Security: Updates, Trustjacking, Breach Detection

  • Security updates for Monday
  • iOS Trustjacking – A Dangerous New iOS Vulnerability
    An iPhone user's worst nightmare is to have someone gain persistent control over his/her device, including the ability to record and control all activity without even needing to be in the same room. In this blog post, we present a new vulnerability called “Trustjacking”, which allows an attacker to do exactly that. This vulnerability exploits an iOS feature called iTunes Wi-Fi sync, which allows a user to manage their iOS device without physically connecting it to their computer. A single tap by the iOS device owner when the two are connected to the same network allows an attacker to gain permanent control over the device. In addition, we will walk through past related vulnerabilities and show the changes that Apple has made in order to mitigate them, and why these are not enough to prevent similar attacks.
  • What Is ‘Trustjacking’? How This New iOS Vulnerability Allows Remote Hacking?
    This new vulnerability called trustjacking exploits a convenient WiFi feature, which allows iOS device owners to manage their devices and access data, even when they are not in the same location anymore.
  • Breach detection with Linux filesystem forensics
    Forensic analysis of a Linux disk image is often part of incident response to determine if a breach has occurred. Linux forensics is a different and fascinating world compared to Microsoft Windows forensics. In this article, I will analyze a disk image from a potentially compromised Linux system in order to determine the who, what, when, where, why, and how of the incident and create event and filesystem timelines. Finally, I will extract artifacts of interest from the disk image. In this tutorial, we will use some new tools and some old tools in creative, new ways to perform a forensic analysis of a disk image.
