  • Linux 5.2
    So 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, and with spotty internet for a few days before that [*].
    
    But there really doesn't seem to be any reason for another rc, since
    it's been very quiet. Yes, I had a few pull requests since rc7, but
    they were all small, and I had many more that are for the upcoming
    merge window. Part of it may be due to the July 4th week, of course,
    but whatever - I'll take the quiet week as a good sign.
    
    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.
    
    There's no particular area that stands out there - the changes are so
    small that the sppended shortlog really is the best description of
    last week. A few small random changes all over: drivers,
    architectures, filesystem, mm, ...
    
    So with this, the merge window for 5.2 is open.

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

    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."

  • Linux 5.2 Kernel Released As The "Bobtail Squid"

    Adding to the excitement of 7 July is the release of the Linux 5.2 stable kernel, which also means the opening of the Linux 5.3 merge window.

    Linux 5.2.0 made it out today on time without having any extra release candidates for this summer 2019 kernel release. This kicks off the Linux 5.3 merge window and its series of release candidates that then should debut as stable in September.

    See our Linux 5.2 feature overview for those wondering about all of the exciting features of this new kernel.

  • The 5.2 kernel has been released

    Linus Torvalds has released the 5.2 kernel. He originally planned for an rc8 this week, rather than 5.2, due to his travel schedule, but was pleasantly surprised at how calm things have been.

Linux Kernel 5.2 Released, This is What’s New

  • Linux Kernel 5.2 Released, This is What’s New

    Arriving pretty much bang on schedule, the Linux kernel 5.2 release was announced to the world with little of Linus Torvalds’ usual fanfare.

    Instead, the Linux founder opted for a quiet introduction when announcing the update on the Linux Kernel Mailing List.

    He writes: “…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”.

    Each and every update to the Linux kernel, be it big or small, brings a stack of welcome improvements, drivers, hardware support, graphics compatibility and more. Linux Kernel 5.2, dubbed the “Bobtail Squid” (blame Linus’ scuba diving hobby the moniker), is no exception.

  • Double delight for Linux lovers as kernel 5.2 and Debian 10 debut

    The weekend has given Linux users two big new releases to contemplate!

    Those who like new cuts of the kernel have version 5.2 to consider. Linus Torvalds signed it off on Monday, Australian time.

    The biggest feature in 5.2 is probably support for Intel’s forthcoming Comet Lake architecture, which will power the tenth generation of its Core desktop and mobile CPUs due. The new silicon is due to ship late in 2019 and appear in products early the next year. Linux 5.2 also includes many tweaks that improve its performance on laptops.

    The kernel also now supports a handful of extra ARM-powered single-board computers.

    The other big new release is Debian 10 “Buster”, which officially debuted on Sunday 7 July, Australian time. But this cut of Debian had actually already been available since 25 June as part of the new version of Raspbian OS, the Raspberry Pi Foundation’s preferred OS for its single board computers.

    The Foundation described Buster as offering “no huge differences” compared to its predecessor. “In a sad reflection of the way the world is nowadays, most of the differences are security changes designed to make Buster harder to hack,” wrote Simon Long, a senior principal software engineer at the Pi Foundation.

  • Linux Kernel 5.2 released, here is what’s new

    Despite the busy schedule of Linus Torvalds, we’re still getting a significant release in Linux Kernel 5.2 instead of just a release candidate.

    In the original news source, the king of the Linux world, Linus Torvalds, has claimed that he was possibly going to drop another release candidate as he was having internet problems for a few days and then got busy with his travels. Luckily, Linus didn’t stick to his plan owing to the lack of pull requests since rc7 and the fact that there seemed to be no real need for another release candidate. Thus, the announcement was made for the release of Linux Kernel 5.2, codenamed Bobtail Squid.

    [...]

    The key highlights of this release are new drivers, extended hardware support, performance improvements, and security fixes. However, Linux Kernel 5.2 is a mainline version, which is usually not suitable for mass deployments. Accordingly, FOSSLinux suggests its readers wait for Linux Kernel 5.2.1 to drop before upgrading their kernels.

  • What's New in Linux 5.2?

    Linux 5.2 has been released. This release includes Sound Open Firmware, a project that brings open source firmware to DSP audio devices; open firmware for many Intel products is also included. This release also improves the Pressure Stall Information resource monitoring to make it usable by Android; the mount API has been redesigned with new syscalls; the BFQ I/O scheduler has gained some performance improvements; a new CLONE_PIDFD flag lets clone(2) return pidfs usable by pidfd_send_signal(2); Ext4 has gained support for case-insensitive name lookups; there is also a new device mapper target that simulates a device that has failing sectors and/or read failures; open source drivers for the ARM Mali t4xx and newer 6xx/7xx have been added. Many other new drivers, features and changes can be found in the changelog.

    Kernel Kitten here, defender of the Linux kernel, commander of the Kitten Army, sworn to protect Commander Torvalds' intellectual property, and look dead cute while we do it.

    We cats aren't designed for summer. All we want to do is try and hide from the sun as much as possible. It starts with leaving the back door open to give us options, but will they? Oh no. Typical.

    Anyway, I've stepped away from the battalion in order to give you details of the latest updates, so hopefully, in line with my new calm, empathetic, zen persona, I'll be able to keep my temper and get on with telling you what you need to know for once.

  • Linux 5.2 releases with inclusion of Sound Open Firmware project, new mount API, improved pressure stall information and more

    Two days ago, Linus Torvalds, the principal developer of the Linux kernel announced the release of Linux 5.2 in his usual humorous way, describing it as a ‘Bobtail Squid’. The release has new additions like the inclusion of the Sound Open Firmware (SOF) project, improved pressure stall information, new mount API, significant performance improvements in the BFQ I/O scheduler, new GPU drivers, optional support for case-insensitive names in ext4 and more. The earlier version, Linux 5.1 was released exactly two months ago.

    Torvalds says, “there really doesn’t seem to be any reason for another rc, since it’s been very quiet. Yes, I had a few pull requests since rc7, but they were all small, and I had many more that are for the upcoming merge window. 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.”

    Linux 5.2 also kicks off the Linux 5.3 merge window.

Ubuntu/Debian: Comparison of Memory Usages, Ubuntu 18.10 (Cosmic Cuttlefish) End of Life and More

  • Comparison of Memory Usages of Ubuntu 19.04 and Flavors in 2019

    Continuing my previous Mem. Comparison 2018, here's my 2019 comparison with all editions of Ubuntu 19.04 "Disco Dingo". The operating system editions I use here are the eight: Ubuntu Desktop, Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio, Ubuntu Kylin, and Ubuntu Budgie. I installed every one of them on my laptop and (immediately at first login) took screenshot of the System Monitor (or Task Manager) without doing anything else. I present here the screenshots along with each variant's list of processes at the time I took them. And, you can download the ODS file I used to create the chart below. Finally, I hope this comparison helps all of you and next time somebody can make better comparisons.

  • Ubuntu 18.10 (Cosmic Cuttlefish) End of Life reached on July 18 2019
    This is a follow-up to the End of Life warning sent earlier this month
    to confirm that as of today (July 18, 2019), Ubuntu 18.10 is no longer
    supported.  No more package updates will be accepted to 18.10, and
    it will be archived to old-releases.ubuntu.com in the coming weeks.

  • CMake leverages the Snapcraft Summit with Travis CI to build snaps

    CMake is an open-source, cross-platform family of tools designed to build, test and package software. It is used to control the software compilation process and generate native makefiles and workspaces that can be used in any compiler environment.  While some users of CMake want to stay up to date with the latest release, others want to be able to stay with a known version and choose when to move forward to newer releases, picking up just the minor bug fixes for the feature release they are tracking. Users may also occasionally need to roll back to an earlier feature release, such as when a bug or a change introduced in a newer CMake version exposes problems within their project. Craig Scott, one of the co-maintainers of CMake, sees snaps as an excellent solution to these needs. Snaps’ ability to support separate tracks for each feature release in addition to giving users the choice of following official releases, release candidates or bleeding edge builds are an ideal fit. When he received an invitation to the 2019 Snapcraft Summit, he was keen to work directly with those at the pointy end of developing and supporting the snap system.

  • Latest Huawei 'Smoking Gun' Still Doesn't Prove Global Blackball Effort's Primary Justification

    We've noted a few times now how the protectionist assault against Huawei hasn't been supported by much in the way of public evidence. As in, despite widespread allegations that Huawei helps China spy on Americans wholesale, nobody has actually been able to provide any hard public evidence proving that claim. That's a bit of a problem when you're talking about a global blackballing effort. Especially when previous investigations as long as 18 months couldn't find evidence of said spying, and many US companies have a history of ginning up security fears simply because they don't want to compete with cheaper Chinese kit. That said, a new report (you can find the full thing here) dug through the CVs of many Huawei executives and employees, and found that a small number of "key mid-level technical personnel employed by Huawei have strong backgrounds in work closely associated with intelligence gathering and military activities."

  • No love lost between security specialists and developers

    Unless you've been under a rock, you've noticed hardly a day goes by without another serious security foul-up. While there's plenty of blame to go around for these endless security problems, some of it goes to developers who write bad code. That makes sense. But when GitLab, a DevOps company, surveyed over 4,000 developers and operators, they found 68% of the security professionals surveyed believe it's a programmer's job to write secure code, but they also think less than half of developers can spot security holes.

  • GitLab Survey Surfaces Major DevSecOps Challenges Ahead

    A report based on a survey of 4,071 software professionals published this week by GitLab, a provider of a continuous integration and continuous deployment (CI/CD) platform, found that while appreciation of the potential value of DevSecOps best practices is high, the ability to implement those practices is uneven at best.

  • GitLab Survey Reveals Disconnect Between Developer And Security Teams

    In a survey conducted by GitLab, software professionals recognize the need for security to be baked into the development lifecycle, but the survey showed long-standing friction between security and development teams remain. While 69% of developers say they’re expected to write secure code, nearly half of security pros surveyed (49%) said they struggle to get developers to make remediation of vulnerabilities a priority. And 68% of security professionals feel fewer than half of developers are able to spot security vulnerabilities later in the lifecycle.

  • Doctorow's novella "Unauthorized Bread" explains why we have to fight DRM today to avoid a grim future

    Salima has a problem: her Boulangism toaster is locked down with software that ensures that it will only toast bread sold to her by the Boulangism company… and as Boulangism has gone out of business, there's no way to buy authorized bread. Thus, Salima can no longer have toast. This sneakily familiar scenario sends our resourceful heroine down a rabbit hole into the world of hacking appliances, but it also puts her in danger of losing her home -- and prosecution under the draconian terms of the Digital Millennium Copyright Act (DMCA). Her story, told in the novella “Unauthorized Bread,” which opens Cory Doctorow’s recent book Radicalized, guides readers through a process of discovering what Digital Restrictions Management (DRM) is, and how the future can look mightily grim if we don’t join forces to stop DRM now. “Unauthorized Bread” takes place in the near future, maybe five or ten years at most, and the steady creep of technology that takes away more than it gives has simply advanced a few degrees. Salima and her friends and neighbors are refugees, and they live precariously in low-income housing equipped with high-tech, networked appliances. These gizmos and gadgets may seem nifty on the surface, but immediately begin to exact an unacceptable price, since they require residents to purchase the expensive approved bread for the toaster, the expensive approved dishes for the dishwasher, and so on. And just as Microsoft can whisk away ebooks that people “own” by closing down its ebook service, the vagaries of the business world cause Boulangism to whisk away Salima’s ability to use her own toaster.

  • New Linux Malware Called EvilGnome Discovered; First Preview of Fedora CoreOS Now Available; Germany Bans Schools from Using Microsoft, Google and Apple; VirtualBox 6.0.10 Released; and Sparky 5.8 Has New Live/Install Media for Download

    Germany has banned its schools from using cloud-based productivity suites from Microsoft, Google, and Apple, because the companies weren't meeting the country's privacy requirements. Naked Security reports, that the statement from the Hessische Beauftragte für Datenschutz und Informationsfreiheit (Hesse Commissioner for Data Protection and Freedom of Information, or HBDI) said, "The digital sovereignty of state data processing must be guaranteed. With the use of the Windows 10 operating system, a wealth of telemetry data is transmitted to Microsoft, whose content has not been finally clarified despite repeated inquiries to Microsoft. Such data is also transmitted when using Office 365." The HBDI also stressed that "What is true for Microsoft is also true for the Google and Apple cloud solutions. The cloud solutions of these providers have so far not been transparent and comprehensible set out. Therefore, it is also true that for schools, privacy-compliant use is currently not possible."
