    In this video, I am going to show an overview of Netrunner 19.08 Indigo and some of the applications pre-installed.

  • How to use the LXD Proxy Device to map ports between the host and the containers

    LXD supports proxy devices, which is a way to proxy connections between the host and containers. This includes TCP, UDP and Unix socket connections, in any combination between each other, in any direction. For example, when someone connects to your host on port 80 (http), then this connection can be proxied to a container using a proxy device. In that way, you can isolate your Web server into a LXD container. By using a TCP proxy device, you do not need to use iptables instead.

    There are 3³=9 combinations for connections between TCP, UDP and Unix sockets, as follows. Yes, you can proxy, for example, a TCP connection to a Unix socket!

  • Management of snaps in a controlled, enterprise environment

    Few enterprises want all their computing devices to be fully exposed to the internet. In an environment of ever-growing security threats, isolating internal networks from the wider internet is not simply best practice, but borderline essential.

    However, with all the benefits that restricted networks provide, it can pose challenges for enterprises who are looking to take advantage of certain technologies. One of these is the automatic update feature of snaps which enable a low-friction process and a fast release cadence. If an enterprise has a restricted network, then this will prevent snaps being able to automatically update due to the necessity for an external internet connection and potentially upsetting change management policies.

  • Dominique Leuenberger: openSUSE Tumbleweed – Review of the week 2019/3

    Seems we’re settling at 3 snapshots per week. It seems to be pretty hard at the moment to get stagings fully built and tested (build are constrained by only few workers able to build e.g. Firefox, and since Leap started the dev cycle, the load on OBS and those few workers massively increased). So, 3 snapshots, or roughly one every other day, does not sound so bad overall. During this week, we released  0829, 0902 and 0904.

  • Improved Common Agricultural Policy compliance with publicly available and user-generated data

    The open source RECAP platform is currently available under the GNU General Public License. The remote sensing components are also market-ready. Both can be hosted either on project partners' servers or on the client's own servers.

How should open source projects handle copyright notices?

Copyright notices in source code are inconsistently applied and poorly maintained. As a result, such notices are poor sources of information. Should more resources be applied to the maintenance of copyright notices? No. Copyright notices are one-line strings that typically include the word "Copyright" (or some substitute, like ©), a name (usually a person or company), and a year. In this article, I am not focusing on licenses or license notices (which may sometimes include a copyright notice). My suggestion for low prioritization of investment in copyright notice maintenance does NOT apply to license information. License information should be clearly presented and maintained to be accurate. If you invite others to take and do something with your software, please make the permissions that are being given clear by presenting and maintaining clear license information. Read more

Firefox 82 is Out with New Sync Options, Malicious Download Blocking

Firefox 82 is due for formal release later today (October 20) but as that tend to happen when I’m in bed I’m posting this post a tiny bit early. Firefox 82 downloads are up on the release server. Indeed, feature development for Firefox seems to be slowing down in general — Mozilla did recently sack a sizeable chunk of the brower’s development team — but a welcome round of enhancements and changes are available through this uplift.

Ubuntu and Debian Get Patches for Bluetooth Remote Code Execution Flaws, Update Now

Discovered by security researcher Andy Nguyen in Linux kernel's Bluetooth L2CAP and Bluetooth A2MP implementation, as well as the Bluetooth HCI event packet parser, the CVE-2020-12351, CVE-2020-12352, and CVE-2020-24490 vulnerabilities are affecting Debian GNU/Linux 10, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 16.04 LTS. While CVE-2020-12351 and CVE-2020-24490 could allow a physically proximate remote attacker to crash the system by causing a denial of service or execute arbitrary code, CVE-2020-12352 let physically proximate remote attackers to expose sensitive information (kernel memory).

Graphics: Intel, AMD and Vulkan

  • Intel Lands A Hefty Tiger Lake Graphics Optimization - Phoronix

    From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake. For Tiger Lake (and theoretically Rocket Lake as well), a new and significant optimization landed today in Mesa 20.3-devel. The optimization applies for Intel Gen12 graphics except for discrete/DG1 graphics.

  • Vulkan Specification Version 1.2.158 Brings Two New Extensions

    Version 1.2.158 of the Vulkan specification introduces VK_KHR_fragment_shading_rate that lets developers change the rate at which fragments are shaded on a per-region, per-primitive or per-draw basis and VK_KHR_shader_terminate_invocation which, together with the previously introduced VK_EXT_shader_demote_to_helper_invocation extension, lets developers do a much more specific OpKill.

  • Open-Source RADV Vulkan Driver Is Seeing Work To Allow Building It On Windows - Phoronix

    An independent party has slowly begun merging patches into mainline Mesa for allowing the open-source Radeon Vulkan driver "RADV" to build on Microsoft Windows. AMD is not behind this effort nor Valve but has been worked on in recent months for making Mesa's Radeon Vulkan driver code compatible with Windows. James Park of a little known "Lag Free Games" has been behind this initiative to bringing it to Windows and seemingly only explaining in private to upstream Mesa developers his motivations for doing so. RADV as a reminder is the Mesa Radeon Vulkan driver started out by David Airlie of Red Hat and Bas Nieuwenhuizen of Google in the time while waiting for AMD to open-source their Vulkan driver. AMD ultimately provided "AMDVLK" as their official open-source Vulkan driver derived from their internal Vulkan driver sources and built against the AMDGPU LLVM compiler back-end.
