  • Systemd Has A New Logo As Other Features Build Up For The Next Release

    The newest feature of systemd is... a new logo.

    At the end of September the quiet FreeDesktop.org Wiki was updated pointing to a new logo. As of Wednesday, the GitHub README was also updated with this new logo as well.

  • VirtualBox Guest Shared Folder Support Coming To The Mainline Linux Kernel

    The mainline Linux kernel continues to see better support for Oracle VM VirtualBox with more of the guest drivers reaching the mainline kernel to provide a vastly better out-of-the-box experience.

    Red Hat's Hans de Goede has been working to nurse many of the open-source VirtualBox drivers into the mainline kernel. The most recent is getting the "VBOXSF" driver queued into Greg KH's staging-linus branch. With it hitting the staging-linus branch overnight rather than staging-next, it's likely this VirtualBox VBOXSF driver is going to be sent in shortly as a fix/addition for the Linux 5.4 kernel cycle since there is little risk of regression.

  • Intel's ANV Vulkan Driver Overhauls Its Buffer Allocation Code

    With Mesa 19.3 having been branched yesterday, hitting Git master today as an early change for Mesa 20.0 is an overhaul to the Intel "ANV" open-source Vulkan driver's buffer object (BO) allocation code.

    The set of patches by Jason Ekstrand, one of Intel's original ANV Vulkan driver developers, changes their allocation code around so that now everything is allocated from the buffer object cache. With this fundamental change all allocations are within a single sparse array struct. This change ensures relocation updates can't crash, moving from a hash set to sparse array for buffer object tracking should be much faster ("this will be much more performant," says Jason), allows a lock in their softpin code to be removed, and is a code clean-up itself. With this change the Intel Vulkan driver is also zeroing out buffers on release to ensure the memory is cleared.

Canonical Releases Major Ubuntu Kernel Updates to Address 14 Vulnerabilities

A total of 14 security vulnerabilities have been fixed in these new major Ubuntu kernel updates, including a race condition (CVE-2020-0423) that may lead to a use-after-free vulnerability, discovered in Linux kernel’s binder IPC implementation. This flaw affects Ubuntu 20.10, Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS systems, and could allow a local attacker to cause a denial of service (system crash) or possibly execute arbitrary code. Affecting all supported Ubuntu releases, this kernel update addresses a Bluetooth security vulnerability (CVE-2020-10135) discovered by Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen, which could allow a physically proximate attacker to impersonate a previously paired Bluetooth device.

5 collaboration tips for using an open source alternative to Google Docs

ONLYOFFICE Docs is highly flexible in how you can store documents. By default, you can use ONLYOFFICE Docs within an ONLYOFFICE Workspace. This provides a productivity solution for managing documents and projects. It's the clear way to use ONLYOFFICE Docs because it's included; when you install one, you get the other. However, the full ONLYOFFICE suite can be integrated with ownCloud, Nextcloud, and other popular sync and share platforms. Helpful connectors are available in your sharing platform's official app store or on GitHub. Read more
