Security: Updates, SDNs, Oklahoma’s Department of Securities (ODS)

Filed under
  • Security updates for Monday
  • Break free from traditional network security

    From a security stance, the network is becoming perimeterless, and rather than a hard network barrier, the corporate network needs to be porous; security inside the network has to be zero-trust.

    The experts Computer Weekly contacted regarding perimeterless network security generally agree that such an architecture is not easy to achieve, but software-defined networking (SDN) and containerisation offer network security architects a sound foundation on which to implement a perimeterless network security strategy.

  • State agency exposes 3TB of data, including FBI info and remote logins

    Oklahoma’s Department of Securities (ODS) exposed three terabytes of files in plain text on the public internet this month, which contained sensitive data including social security numbers, details of FBI investigations, credentials for remote access to computers, and the names of AIDS patients.

    Researchers at security company UpGuard found the files using the Shodan search engine, which indexes internet-connected devices. In this case, they ran across an unsecured rsync server registered to ODS.

    Rsync is a utility commonly found on Unix and Linux systems that enables administrators to synchronize files between different computers. It is used for ‘delta’ syncing, in which one computer copies to another only the parts of files that have changed, enabling them to maintain identical copies of the files in different locations.

  • Daniel Stenberg: QUIC and missing APIs

    I trust you’ve heard by now that HTTP/3 is coming. It is the next destined HTTP version, targeted to get published as an RFC in July 2019. Not very far off.

    HTTP/3 will not be done over TCP. It will only be performed over QUIC, which is a transport protocol replacement for TCP that always is done encrypted. There’s no clear-text version of QUIC.

  • Huge Supercomputers Still Exist. Here’s What They’re Being Used for Today

    The term “Supercomputer” implies one gigantic computer many times more powerful than your simple laptop, but that couldn’t be farther from the case. Supercomputers are made up of thousands of smaller computers, all hooked up together to perform one task. Each CPU core in a datacenter probably runs slower than your desktop computer. It’s the combination of all of them that makes computing so efficient. There’s a lot of networking and special hardware involved in computers of this scale, and it isn’t as simple as just plugging each rack into the network, but you can envision them this way, and you wouldn’t be far off the mark.

    Not every task can be parallelized so easily, so you won’t be using a supercomputer to run your games at a million frames per second. Parallel computing is usually good at speeding up very calculation-oriented computing.

    Supercomputers are measured in FLOPS, or Floating Point Operations Per Second, which is essentially a measure of how quickly it can do math. The fastest one currently is IBM’s Summit, which can reach over 200 PetaFLOPS, a million times faster than “Giga” most people are used to.

  • Google dominates code contributions across Cloud Native Computing Foundation projects

    Even without counting Kubernetes, Google is far and away the largest code contributor to the Cloud Native Computing Foundation (CNCF) open source group.

    Google accounts for 53% of all code commits to the Linux Foundation's CNCF and has seven times more contributions than Red Hat, which only accounted for 7.4% of the contributed code.

    The analysis of code contributions was done by Stackalytics, which is an open source code analysis framework that is hosted by the OpenStack Foundation and sponsored by Mirantis.

OpenSUSE/SUSE: SLES for SAP and Christian Boltz Introduced

Filed under
  • SUSE Linux Enterprise Server for SAP Applications support update

    SUSE has announced effective December 1, 2018, two changes to its SUSE Linux Enterprise Server (SLES) for SAP Applications product.
    SLES for SAP Applications now includes support for a given service pack for 4.5 years with the regular subscription while the basic codestream is general available and itself fully maintained. This change reflects the request from clients to align OS upgrades with hardware life cycles.
    To explain this a bit further, this change affects SLES for SAP Applications 12 and 15 code streams. SLES for SAP Applications 11 is at the end of the general availability already, therefore SLES for SAP Applications 11 SP4 is the last service pack. If clients choose to stay on SLES for SAP Applications 11, then they will need to purchase LTSS to ensure ongoing support. This is especially true for clients that run SAP HANA 1 workloads on IBM Power Systems servers in Big Endian mode.

  • Homebrew 1.9 Adds Linux Support, Auto-Cleanup, and More

    The latest release of popular macOS package manager Homebrew includes support for Linux, optional automatic package cleanup, and extended binary package support.

    Linux support, merged from the Linuxbrew project, is still in beta and will become stable in version 2.0. It also enables the use of Homebrew on Windows 10 systems with the Windows Subsystem for Linux installed.

    Auto-cleanup is meant to optimize disk space occupation by removing all intermediate data that Homebrew generates when installing packages. This can be a significant amount when Homebrew actually builds the packages from sources instead of just installing binaries. Auto-cleanup is opt-in by setting the HOMEBREW_INSTALL_CLEANUP. This behaviour will become opt-out in version 2.0, where you will be able to set the HOMEBREW_NO_INSTALL_CLEANUP environment variable to disable auto-cleanup.

  • Counteracting Code Complexity With Wily - Episode 195

    As we build software projects, complexity and technical debt are bound to creep into our code. To counteract these tendencies it is necessary to calculate and track metrics that highlight areas of improvement so that they can be acted on. To aid in identifying areas of your application that are breeding grounds for incidental complexity Anthony Shaw created Wily. In this episode he explains how Wily traverses the history of your repository and computes code complexity metrics over time and how you can use that information to guide your refactoring efforts.

  • Ben Cotton: Inclusion is a necessary part of good coding

    Too often I see comments like “some people would rather focus on inclusion than write good code.” Not only is that a false dichotomy, but it completely misrepresents the relationship between the two. Inclusion doesn’t come at the cost of good code, it’s a necessary part of good code.

    We don’t write code for the sake of writing code. We write code for people to use it in some way. This means that the code needs to work for the people. In order to do that, the people designing and implementing the technology need to consider different experiences. The best way to do that is to have people with different experiences be on the team. As my 7th grade algebra teacher was fond of reminding us: garbage in, garbage out.

Graphics: Vega, Radeon, Wayland on BSD

  • Vega 10 & Newer Getting More Fine-Grained PowerPlay Controls On Linux

    With the upcoming Linux 5.1 kernel cycle, discrete Radeon graphics cards based on Vega 10 and newer will have fine-grained controls over what PowerPlay power management features are enabled and the ability to toggle them at run-time.

    Queued into the work-in-progress AMDGPU code for the eventual Linux 5.1 kernel cycle is now a ppfeatures for sysfs. This new "ppfeatures" file on sysfs will allow for querying the PowerPlay features state and toggling them individually. This includes features like GFXOFF (the ability to turn off the graphics engine when idling), automatic fan control, LED display for GPU activity, the dynamic power management state for the various blocks, and other features. Up to now the PowerPlay features couldn't be toggled individually but just a blanket enable/disable.

  • AMD Radeon 7 Will Have Day One Linux Support

    Linux gamers shouldn't see a repeat performance of the Radeon RX 590 situation.

  • Wayland Support On The BSDs Continuing To Improve

    While Wayland was designed on and for Linux systems, the BSD support for Wayland and the various compositors has continued improving particularly over the past year or so but it's still a lengthy journey.

    In a little more than one year, the FreeBSD Wayland support has been on a steady rise. It's looking like this year could even mark the KDE Wayland session for FreeBSD potentially getting squared away. Besides KDE, the GNOME Wayland work for FreeBSD has advanced a bit and is available in some FreeBSD Ports but there has been some complications around libinput and its Linux'isms. Details on the current state of Wayland-related components in FreeBSD is drafted at the FreeBSD Wiki.

Mesa 18.2 vs. 18.3 vs. 19.0 January Benchmarks For RadeonSI/RADV

Filed under

With Mesa 19.0 entering its feature freeze before the month is through, here are fresh benchmarks of the very latest RadeonSI OpenGL and RADV Vulkan performance on Polaris and Vega graphics cards compared to the current stable Mesa 18.3 series and the former 18.2 release. This testing is complementary to last week's Mesa 19.0 RADV vs. AMDVLK vs. AMDGPU-PRO Vulkan tests.

For the purposes of seeing how the latest Mesa 19.0 is stacking up on the Radeon side, tests were done with a Radeon RX 580 Polaris and Radeon RX Vega 56. Tests were done using Mesa 19.0-devel from the Padoka PPA built against LLVM 8.0 SVN AMDGPU and then against Mesa 18.3.1 stable with LLVM 7.0.0 (from the Pkppa) and then Mesa 18.2.2 built against LLVM 7.0 as is shipped by default currently on Ubuntu 18.10. So not only are we looking to see the current performance benefits of Mesa 19 but also whether the performance upgrade is worthwhile for those otherwise using the stock Mesa shipped by the current Ubuntu release.

12 Best Free Linux Project Management Software (Updated 2019)

Filed under

Project management tools encompass many different types of software such as scheduling, resource allocation, collaboration software, quality management, and cost control / budget management. This type of software is typically used by project managers looking to plan and control resources, costs and schedules to meet the objectives of a project.

To help plan a project, there are a number of different types of project management tools. One of the industry standards is the Gantt Chart, which provides a graphical displays of all the tasks that a project is composed of. Each bar on the chart is a graphical representation of the length of time the task is planned to take. Other popular tools include PERT charts (a method for analyzing the tasks involved in completing a project), Product Breakdown Structure (a hierarchical tree structure of components that make up a project deliverable), and Work Breakdown Structure (a hierarchical tree structure of deliverables and tasks that need to be performed to complete a project).

Project management tools offer many advantages when it comes to project planning and tracking. Gantt charts are synonymous with project management. The ability to get an overview of a project visually in the form of a simple to understand chart should not be underestimated. But good project management software offers so much more functionality.

  • Why did Fedora Modularity fail in 2017? A brief reflection

    For the ISTE-430 Information Requirements Modelling course at the Rochester Institute of Technology, students are asked to analyze an example of a failed software project and write a short summary on why it failed. For the assignment, I evaluated the December 2017 announcement on Fedora Modularity. I thought it was an interesting example of a project that experienced initial difficulty but re-calibrated and succeeded in the end. And it is a project I am biased towards, as a Fedora user and sysadmin.

    I thought sharing it on my blog might be interesting for others. Don’t read into this too much – it was a quick analysis from a single primary source and a few secondary references.

  • Some Radeon ROCm Packages Pending Review For Fedora

    Earlier this month was word that Fedora developers were looking at packaging Radeon Open Compute (ROCm) to make it easier for their distribution users to enjoy this open-source Radeon GPU computing software from OpenCL to a TensorFlow port. Some of the early packages of ROCm are now under review for Fedora.

  • A Red Hat-backed open source project warns that a controversial new plan to take on Amazon and other tech titans is only causing 'Fear, Uncertainty, and Doubt'

    Open source software companies like MongoDB are making drastic moves to protect their intellectual property from cloud giants like Amazon or Alibaba — but a clash between MongoDB and $31 billion software giant Red Hat highlights the potential pitfalls of that strategy.

    Fedora, a Red Hat-sponsored open source operating system, has dropped support for the very popular MongoDB database. Although Fedora is sponsored by Red Hat, and has project leaders who work at Red Hat, it's technically a separately-run open source project. Fedora cited concerns over the company's controversial new licensing agreement, and indeed, Fedora has tacked MongoDB's SSPL onto its "bad license" list.

    This comes months after Red Hat, which is on the cusp of being acquired by IBM, removed MongoDB support from its Red Hat Enterprise Linux OS in November.

    There's a number of Early Access game that I'm keeping a close eye on for having a huge amount of promise, Deadly Days is one such title that has come along very nicely recently.

    It's what the developers are calling a 'unique strategic zombie survival rogue-lite' and that's a pretty reasonable description. You loosely control a group of survivors during the apocalypse and it's your job to oversee their survival. You have 15 days to scavenge what you can, in the hopes of finding some medicine to prevent them turning.

  • I’m in shock at just how well Overwatch runs with the latest DXVK and Lutris

    You might remember, that back in September last year I talked a little about Lutris and Overwatch [Official Site] together and how it was working well. Here’s an update on how it’s been going.

    Overwatch, developed by Blizzard, is an online team-based shooter that feels a lot like Team Fortress 2 from Valve. However, as much as I’ve tried to get into TF2 it just doesn’t stick. TF2 feels like it has no identity, it feels…bland.

    Overwatch on the other hand, is an incredibly exciting experience and I’m still very much a beginner. It has a pretty loud and proud identity, along with various animated shorts which help to suck you into the world. It’s something friends play practically religiously too, so it’s one of those times where I’ve felt a bit left out, well—no more!

    When I tried it previously back in September last year, the performance was pretty good. Fast-forward multiple months, a few new versions of DXVK have come along and the experience is mind-blowing. I don’t want to oversell it, but seriously it’s so smooth I completely forget that the work done to get it working on Linux wasn’t done by Blizzard directly.
