FuryBSD 2020-Q3 The world’s first OpenZFS based live image

Filed under
BSD

FuryBSD is a tool to test drive stock FreeBSD desktop images in read write mode to see if it will work for you before installing. In order to provide the most reliable experience possible while preserving the integrity of the system the LiveCD now leverages ZFS, compression, replication, a memory file system, and reroot (pivot root).

13.0 coming next year will build on this by allowing further enhancements to this solution with the added ztd compression support. Work is also underway with the GhostBSD development team to see if this new methodology is a good fit for that project, and can be integrated.FuryBSD 2020-Q3 The world’s first OpenZFS based live image

Review: GhostBSD 20.08.04, Finnix 121

Filed under
GNU
Reviews
BSD

About a month ago the GhostBSD team published a new release. The GhostBSD operating system is based on FreeBSD and focuses on desktop use. It has a graphical installer, some convenient desktop utilities for handling tasks such as installing updates, and ships with the MATE desktop. There is also a community edition of GhostBSD which runs the Xfce desktop instead of MATE. Both editions run on 64-bit (x86_64) machines exclusively.

Apart from updating MATE to version 1.24.0, the new snapshot of GhostBSD introduces one big change: automated boot environment snapshots during package upgrades. This allows the administrator to have snapshots of the operating system's filesystem taken prior to each package upgrade, ensuring that if something breaks, we can reboot and rollback the system to its previous state. This should make GhostBSD secure against broken updates in a similar fashion to openSUSE when the latter is installed on Btrfs.

OpenZFS Support Merged Into Mainline FreeBSD and OpenZFS 2.0-RC1 Released

Filed under

BSD
  • OpenZFS Support Merged Into Mainline FreeBSD

    Following ongoing work for over a year on moving to OpenZFS for FreeBSD's ZFS file-system support, FreeBSD HEAD overnight has imported the OpenZFS code-base.

    Earlier this year OpenZFS saw the FreeBSD support added. In the months since OpenZFS has continued seeing BSD improvements as well as other improvements on its own like Zstd compression for OpenZFS.

    The milestone now being crossed is the OpenZFS file-system code is imported into FreeBSD HEAD.

  • OpenZFS 2.0-RC1 Released With Unified Linux/BSD Support, Zstd Compression & Much More

    The first release candidate of the forthcoming OpenZFS 2.0 is now available for testing on both Linux and BSD systems.

    OpenZFS 2.0 is a huge feature release for this well maintained, portable open-source ZFS file-system implementation. OpenZFS 2.0 brings unified support for both Linux and now FreeBSD too. FreeBSD just mainlined the OpenZFS code and has been working for many months now on transitioning over to this more maintained and active ZFS file-system code-base.

AMD and Intel (x86) in Linux

  • Linux 5.10 Adding Support For AMD Zen 3 CPU Temperature Monitoring

    The next version of the Linux kernel will allow monitoring temperatures of the upcoming AMD Zen 3 processors. While CPU temperature monitoring support may seem mundane and not newsworthy, what makes this Zen 3 support genuinely interesting is that it's coming pre-launch... This is the first time in the AMD Zen era we are seeing CPU temperature reporting added to the Linux driver pre-launch. Not only is it coming ahead of the CPUs hitting retail channels but the support was added by AMD engineers.

  • FFmpeg Now Supports GPU Inference With Intel's OpenVINO

    Earlier this summer Intel engineers added an OpenVINO back-end to the FFmpeg multimedia framework. OpenVINO as a toolkit for optimized neural network performance on Intel hardware was added to FFmpeg for the same reasons there is TensorFlow and others also supported -- support for DNN-based video filters and other deep learning processing.

  • Intel SGX Enclave Support Sent Out For Linux A 38th Time

    For years now Intel Linux developers have been working on getting their Software Guard Extensions (SGX) support and new SGX Enclave driver upstreamed into the kernel. SGX has been around since Skylake but security concerns and other technical reasons have held up this "SGX Foundations" support from being mainlined. There has also been an apparent lack of enthusiasm by non-Intel upstream kernel developers in SGX. This past week saw the 38th revision to the patches in their quest to upstreaming this support for handling the Memory Encryption Engine (MEE) and relates SGX infrastructure. [...] The Intel SGX foundations v38 code can be found via the kernel mailing list. The Linux 5.10 merge window is opening up next month but remains to be seen if it will be queued for this next cycle or further dragged out into 2021.

  • Intel SGX foundations
    Intel(R) SGX is a set of CPU instructions that can be used by applications
    to set aside private regions of code and data. The code outside the enclave
    is disallowed to access the memory inside the enclave by the CPU access
    control.
    
    There is a new hardware unit in the processor called Memory Encryption
    Engine (MEE) starting from the Skylake microacrhitecture. BIOS can define
    one or many MEE regions that can hold enclave data by configuring them with
    PRMRR registers.
    
    The MEE automatically encrypts the data leaving the processor package to
    the MEE regions. The data is encrypted using a random key whose life-time
    is exactly one power cycle.
    
    The current implementation requires that the firmware sets
    IA32_SGXLEPUBKEYHASH* MSRs as writable so that ultimately the kernel can
    decide what enclaves it wants run. The implementation does not create
    any bottlenecks to support read-only MSRs later on.
    
    You can tell if your CPU supports SGX by looking into /proc/cpuinfo:
    
    	cat /proc/cpuinfo  | grep sgx
    

Latest Progress on KDE Themes and KTechLab

  • Announcing KTechLab 0.50.0

    I’m happy to announce KTechLab release version 0.50.0. KTechLab is an IDE for microcontrollers and electronics. In this new release every user-visible functionality is the same as in previous releases, however, the codebase of KTechLab has been updated, so now it is a KF5/Qt5 application and it does not depend anymore on KDELibs4Support libraries. This release should compile and run on systems where KDELibs4Support libraries are not available. In its current state KTechLab’s codebase is ready for fixes and enhancements, as it only depends on modern libraries like KDE Frameworks 5 (KF5) and Qt5. As a side note, KF6 and Qt6 have been announced, and the first release of Qt6 has been scheduled to the end of 2020.

  • KTechLab git master doesn't depend on deprecated Qt5/KF5 API anymore

    KTechLab git master doesn’t depend anymore on deprecated Qt5/KF5 APIs. Thank you for everybody who made this possible! Using only up-to-date APIs should help with long-term maintenance of KTechLab and probably it helps distributors of KTechLab, too.

Review: Garuda Linux 200817

One of the more recent additions to the DistroWatch database is Garuda Linux, an Arch-based distribution that offers several enticing features. By default Garuda is intended to be run on the Btr file system, which offers all sorts of attractive features such as multi-disk storage volumes and snapshots. Btrfs has been paired with Timeshift on Garuda and the system is reported to take automatic snapshots before each package upgrade, making the system much easier to recover. I especially like the idea of having automated filesystem snapshots on a rolling release distribution such as Arch. The openSUSE Tumbleweed rolling release has offered automatic snapshots of the system prior to upgrades for a while now and it is nice to see this feature catching on in other projects. The Garuda distribution ships with the Calamares system installer to make setting up the operating system easier. We are also given a desktop tool for managing drivers and Garuda's website mentions proprietary NVIDIA video drivers are optionally available. Rounding out some of the key features, Garuda ships with the Zen Linux kernel with the goal of providing better desktop performance. Read more
