KDE Applications 19.04 Reaches End of Life, KDE Apps 19.08 Arrives on August 15

Thursday 11th of July 2019 07:40:00 PM
The KDE Project announced today the release and general availability of the third and last maintenance update to the KDE Applications 19.04 open-source software suite series.

Launched on April 18th, 2019, the KDE Applications 19.04 open-source software suite series received a total of three maintenance updates, the last one being released today as KDE Applications 19.04.3, which fixes some remaining issues but also marks the end of life of KDE Applications 19.04.

GNU Linux-Libre 5.2 Kernel Released for Those Seeking 100% Freedom for Their PCs

Tuesday 9th of July 2019 04:16:00 PM
The GNU Linux-libre project has released the GNU Linux-libre 5.2 kernel, a 100% free version of the Linux kernel that doesn't include any proprietary drivers, firmware, or code.

Based on the recently released Linux 5.2 kernel series, which introduces the Sound Open Firmware support for DSP audio devices, the GNU Linux-libre 5.2 kernel also ships with the open-source firmware, which wasn't included in previous versions of the GNU Linux-libre kernel because they were overlooked.

"I had not realized the SOF files were Free Software in recent earlier releases, so the requests for these files were disabled in them," said developer Alexandre Oliva in a mailing list announcement. "Only while cleaning up the new kernel module specifically devoted to SOF-supporting devices did I realize my mistake."

The GNU Linux-libre 5.2 kernel also deblobs several new drivers, including btmtksdio, iqs5xx, is... (read more)

Linux Lite Users Are the First to Try Linux Kernel 5.2, Here's How to Install It

Linux Kernel 5.2 Officially Released, Here's What's New

Sunday 7th of July 2019 11:47:00 PM
Linus Torvalds has announced today the release and general availability of the Linux 5.2 kernel series, a major release that adds several new features, updated drivers, and many improvements.

After seven RCs (Release Candidates), the Linux 5.2 kernel  series is now available and it comes with some very interesting features and enhancements. However, before we dive into what's new, you should know that this release is not a long-term supported (LTS) branch, which means that you stick with your current LTS kernel instead.

"I was somewhat pre-disposed towards making an rc8, simply because of my travels and being entirely off the internet for a few days last week," said Linus Torvalds in a mailing list announcement. "So despite a fairly late core revert, I don't see any real reason for another week of rc, and so we have a v5.2 with the normal release timing."

Ubuntu 18.10 (Cosmic Cuttlefish) Will Reach End of Life on July 18th, 2019

Friday 5th of July 2019 01:30:00 AM
Canonical announced today that the Ubuntu 18.10 (Cosmic Cuttlefish) operating system is approaching end of life later this month, urging users to upgrade to a newer release.

Released last year on October 18th, Ubuntu 18.10 was dubbed as Cosmic Cuttlefish by Canonical's CEO Mark Shuttleworth. It shipped with the GNOME 3.30 desktop environment and the Linux 4.18 kernel series, and featured a fresh new look based on the in-house developed Yaru theme, formerly Communitheme.

Ubuntu 18.10 also brought support for unlocking your PC with your fingerprint, mobile phone integration, as well as support for managing Thunderbolt devices. However, being supported for only nine months, Ubuntu 18.10 will reach end of life on July 18th, 2019, which means it will no longer receive security or software updates.

"Ubuntu announced its 18.10 (Cosmic Cuttlefish) release almost 9 months ago, on October 18, 2018.  As a non-LTS release, 18.10 has a 9-month support cycle and, as such, the s... (read more)

IPFire Open-Source Linux Firewall Now Patched Against SACK Panic Vulnerabilities

Thursday 4th of July 2019 08:48:00 PM
Michael Tremer announced the release of IPFire 2.23 Core Update 134, a new maintenance update to the open-source, hardened, and versatile Linux-based firewall that adds the latest security fixes and component updates.

These are serious flaws and could allow remote attackers to cause a so-called SACK Panic attack (denial of service).

"The Linux kernel was vulnerable for two DoS attacks against its TCP stack. The first one made it possible for a remote attacker to panic the kernel and a second one could trick the system into transmitting very small packets so that a data transfer would have used the whole bandwidth but filled mainly with packet ov...

Linux Mint 20 and Future Releases Will Drop Support for 32-bit Installations

Tuesday 2nd of July 2019 05:15:00 PM
The Linux Mint project announced today that they have decided to follow Canonical's decision to drop support for 32-bit system in future releases of their Ubuntu operating system.

As you might know, Canonical announced last month that they plan to drop support for 32-bit systems all together, not only for new installations, but they ended up realizing that some major projects like Wine and Steam still need 32-bit libraries, so starting with Ubuntu 19.10 (Eoan Ermine) they'll only build select 32-bit packages.

Many users were asking if Ubuntu-based distributions will be affected by this major change, which shoul... (read more)

  • Full Circle Magazine: Full Circle Weekly News #140
  • Christopher Allan Webber: ActivityPub Conf 2019

    That's right! We're hosting the first ever ActivityPub Conf. It's immediately following Rebooting Web of Trust in Prague. There's no admission fee to attend. (Relatedly, the conference is kind of being done on the cheap, because it is being funded by organizers who are themselves barely funded.) The venue, however, is quite cool: it's at the DOX Centre for Contemporary Art, which is itself exploring the ways the digital world is affecting our lives. If you plan on attending (and maybe also speaking), you should get in your application soon (see the flier for details). We've never done one of these, and we have no idea what the response will be like, so this is going to be a smaller gathering (about 40 people). In some ways, it will be somewhere between a conference and a gathering of people-who-are-interested-in-activitypub. As said in the flier, by attending, you are agreeing to the code of conduct, so be sure to read that.

Sysadmin Appreciation Day, IBM and Fedora

  • Gift ideas for Sysadmin Appreciation Day

    Sysadmin Appreciation Day is coming up this Friday, July 26. To help honor sysadmins everywhere, we want you to share your best gift ideas. What would be the best way a team member or customer could show their appreciation for you? As a sysadmin, what was the best gift you've ever received? We asked our writers the same question, and here are their answers: "Whilst working in the Ubuntu community on Edubuntu, I took it upon myself to develop the startup/shutdown sound scheme, which became the default in Ubuntu for, from what I can understand, the next decade. Whilst people had a love-hate relationship with my sound scheme, and rightly so, I had a love-hate relationship with my sound card during the development. At the time I had recorded all my sound samples using one sample rate, but my new sound card, as my motherboard had exploded a few days earlier, did not support it. I had two choices, resample all my samples (which I didn't really want to do) or buy a new sound card.

  • Red Hat OpenStack Platform with Red Hat Ceph Storage: Radosbench baseline performance evaluation

    Red Hat Ceph Storage is popular storage for Red Hat OpenStack Platform. Customers around the world run their hyperscale, production workloads on Red Hat Ceph Storage and Red Hat OpenStack Platform. This is driven by the high level of integration between Ceph storage and OpenStack private cloud platforms. With each release of both platforms, the level of integration has grown and performance and automation has increased. As the customer's storage and compute needs for footprints have grown, we have seen more interest towards running compute and storage as one unit and providing a hyperconverged infrastructure (HCI) layer based on OpenStack and Ceph. [...] Continuing the benchmarking series, in the next post you’ll learn performance insights of running multi-instance MySQL database on Red Hat OpenStack Platform and Red Hat Ceph Storage across decoupled and hyperconverged architectures. We’ll also compare results from a near-equal environment backed by all-flash cluster nodes.

  • The State of Java in Flathub

    For maintainers of Java-based applications in Flathub, it's worth noting that even if you consume the Latest OpenJDK extension in your application, users will not be broken by major updates because OpenJDK is bundled into your Flatpak. The implication of this for users is that they won't see updates to their Java version until the application maintainer rebuilds the application in Flathub. If you maintain a Java-based Flatpak application on Flathub, you can consume the latest version of your chosen OpenJDK stream (either LTS or Latest) simply by rebuilding; the latest version of that OpenJDK steam will be pulled in automatically.

  • Fedora Magazine: Contribute at the Fedora Test Week for kernel 5.2

    The kernel team is working on final integration for kernel 5.1. This version was just recently released, and will arrive soon in Fedora. This version has many security fixes included. As a result, the Fedora kernel and QA teams have organized a test week from Monday, Jul 22, 2019 through Monday, Jul 29, 2019.

  • Candy Tsai: Outreachy Week 6 – Week 7: Getting Code Merge

    You can’t overhear what others are doing or learn something about your colleagues through gossip over lunch break when working remotely. So after being stuck for quite a bit, terceiro suggested that we try pair programming. After our first remote pair programming session, I think there should be no difference in pair programming in person. We shared the same terminal, looked at the same code and discussed just like people standing side by side. Through our pair programming session, I found out that I had a bad habit. I didn’t run tests on my code that often, so when I had failing tests that didn’t fail before, I spent more time debugging than I should have. Pair programming gave insight to how others work and I think little improvements go a long way.

  • about your wiki page on I/O schedulers and BFQ
    Hi,
    this is basically to report outdated statements in your wiki page on
    I/O schedulers [1].
    
    The main problematic statement is that BFQ "...  is not ideal for
    devices with slow CPUs or high throughput I/O devices" because too
    heavy.  BFQ is definitely more sophisticated than any of the other I/O
    schedulers.  We have designed it that way to provide an incomparably
    better service quality, at a very low overhead.  As reported in [2],
    the execution time of BFQ on an old laptop CPU is 0.6 us per I/O
    event, against 0.2 us for mq-deadline (which is the lightest Linux I/O
    scheduler).
    
    To put these figures into context, BFQ proved to be so good for
    "devices with slow CPUs" that, e.g., Chromium OS migrated to BFQ a few
    months ago.  In particular, Google crew got convinced by a demo [3] I
    made for them, on one of the cheapest and slowest Chromebook on the
    market.  In the demo, a fast download is performed.  Without BFQ, the
    download makes the device completely unresponsive.  With BFQ, the
    device remains as responsive as if it was totally idle.
    
    As for the other part of the statement, "...  not ideal for ...  high
    throughput I/O devices", a few days ago I ran benchmarks (on Ubuntu)
    also with one of the fastest consumer-grade NVMe SSDs: a Samsung SSD
    970 PRO.  Results [4] can be summarized as follows.  Throughput with
    BFQ is about the same as with the other I/O schedulers (it couldn't be
    higher, because this kind of drives just wants the scheduler to stay
    as aside as possible, when it comes to throughput).  But, in the
    presence of writes as background workload, start-up times with BFQ are
    at least 16 times as low as with the other I/O schedulers.  In
    absolute terms, gnome-terminal starts in ~1.8 seconds with BFQ, while
    it takes at least 28.7 (!) seconds with the other I/O schedulers.
    Finally, only with BFQ, no frame gets lost in video-playing
    benchmarks.
    
    BFQ then provides other important benefits, such as from 5x to 10X
    throughput boost in multi-client server workloads [5].
    
    So, is there any chance that the outdated/wrong information on your
    wiki page [1] gets updated somehow?  If I may, I'd be glad to update
    it myself, after providing you with all the results you may ask.
    
    In addition, why doesn't Ubuntu too consider switching to BFQ as
    default I/O scheduler, for all drives that BFQ supports (namely all
    drives with a maximum speed not above ~500 KIOPS)?
    
    Looking forward to your feedback,
    Paolo
    
    
  • Should Ubuntu Use The BFQ I/O Scheduler?

    The BFQ I/O scheduler is working out fairly well these days as shown in our benchmarks. The Budget Fair Queueing scheduler supports both throughput and low-latency modes while working particularly well for consumer-grade hardware. Should the Ubuntu desktop be using BFQ by default? [...] But in addition to wanting to correct that Wiki information, Paolo pops the question of why doesn't Ubuntu switch to BFQ as the default I/O scheduler for supported drives. Though as of yet, no Ubuntu kernel developers have yet commented on the prospect of switching to BFQ.

Axiomtek has launched a fanless, Kaby Lake-U based transportation computer with a choice of power supplies designed for in-vehicle, marine, or railway applications. The rugged tBOX400-510-FL features a Qualcomm-driven, Layer 2 managed PoE switch with support for IP surveillance and video management applications. “Customers can connect IP cameras directly without installing an extra PoE switch, minimizing overall deployment costs and installation space onboard,” stated Axiomtek product manager Sharon Huang.
