  • SUSE Linux Enterprise Real Time boosts app performance

    a Linux kernel that also offers applications and tools to manage and support a real-time environment. The kernel uses different scheduler queues and makes a distinction between normal processes and real-time processes. If there is a shortage of available resources, the Linux kernel will service the real-time resources first.

  • Boltron - Fedora Modular OS playground!

    Last summer at Flock Langdon White, Ralph Bean and couple folks around them announced work on new release tools and a project called Modularity. The goal was simple but aspirational - for couple years we've talked about rings proposal, splitting applications from the core of the OS, having alternatives available and easily installable for certain components and even though for all of these usecases you could always find a way how to achieve them they weren't really supported by the build infrastructure and software management tools. Once you would update your system or install something else it would usually break or do something unexpected. Modularity goal was to come up with a straightforward way how to deliver a bulk of content thru our build pipeline, offer multiple versions of components and different installation profiles. At the same time this new approach to delivering content would not break existing workflows and will be super easy for package maintainers.

  • Fedora Modular Server "Boltron" Preview Release Now Available

    Fedora developers have announced the first preview release of Boltron, their Modular Server effort. Fedora Modular Server is aiming to separate the lifecycle of applications from each other and the operating system itself. This is part of Fedora's broader modularity efforts while this Boltron preview today is about the server components.

  • Serverless Computing May Offer Better Economics Than Virtual Machines

    Serverless computing is becoming yet another way for cloud service providers to parse out access to enterprises looking to take advantage of virtualized services. Think containers, only slightly different.

    Serverless computing architectures are designed to reduce the amount of overhead associated with offering services in the cloud. This includes the ability for a cloud provider to dynamically manage server resources.

  • This Week in Scalability: System Backups in the Container Era

    As we gear up to release our next e-book on the Kubernetes open source container orchestration engine (check with us in about a month), we have been reviewing how well K8s has been making its way into the enterprise — the true determinant of whether the software becomes an essential component of “the new stack,” so to speak.

    Reviewing our notes from Kubecon 2017, held earlier this year in Berlin, we found some powerful testimonies from both Salesforce and Comcast. Salesforce is using it in a pilot program to power three cloud-native services, with plans to be running 20 services by the end of the year. When the company’s engineers were considering different orchestration options, they immediately appreciated the smarts behind the Kubernetes. After all, many had come from other jobs managing large at-scale workloads. “We were, frankly, blown away. The development velocity was incredible, even back then,” Salesforce Principal Architect Steve Sandke said of the developers behind Kubernetes. “These people clearly knew what they were doing.”

  • Federal Cloud Computing

    Open source software (OSS) and cloud computing are distinctly different concepts that have independently grown in use, both in the public and private sectors, but have each faced adoption challenges by federal agencies. Both OSS and cloud computing individually offer potential benefits for federal agencies to improve their efficiency, agility, and innovation, by enabling them to be more responsive to new or changing requirements in their missions and business operations. OSS improves the way the federal government develops and also distributes software and provides an opportunity to reduce costs through the reuse of existing source code, whereas cloud computing improves the utilization of resources and enables a faster service delivery.

  • Docker Leads OCI Release of v1.0 Runtime and Image Format Specifications

    Today marks an important milestone for the Open Container Initiative (OCI) with the release of the OCI v1.0 runtime and image specifications – a journey that Docker has been central in driving and navigating over the last two years. It has been our goal to provide low-level standards as building blocks for the community, customers and the broader industry. To understand the significance of this milestone, let’s take a look at the history of Docker’s growth and progress in developing industry-standard container technologies.

  • The Difference Between SOA and Microservices Isn’t Size

    For those that have been in the technology industry for some time, there is a tendency to compare or even equate the current microservices phenomenon with the more archaic Service Oriented Architecture (SOA) approach. This is done implicitly in many cases, but also quite explicitly with statements such as “microservices is nothing more than the new SOA” or “Amazon is the only company to get SOA right.”

    This is unsurprising, because it’s rooted in fact. For all of its other faults, SOA was a vision of enterprises that looks remarkably like what progressive organizations are building today with cloud native architectures composed of, among other things, microservices. Stripped to its core, SOA was the idea that architectures should be composed of services rather than monolithic applications.

  • OpenSuSE Conference 2017 Nuremberg, Germany

    The event has grown and I felt a relaxed yet productive atmosphere when entering the venue. Just a few minutes after I arrived I hooked up with interesting people with even more interesting discussions. It was very nice to get together with all the Free Software friends I made over the last years. It was also pleasent to see the event becoming bigger and bigger. I take that as a sign that our community grows although it might also just be consolidation of events.

Fujitsu, SUSE, and the YaST Development Sprint

Filed under
SUSE
  • Fujitsu and SUSE unveil ‘SUSE Business Critical Linux’ support
  • Highlights of YaST development sprint 37

    We got a bug report about YaST not responding when a very long package changelog was displaying in the package manager. It turned out that some packages have a huge change log history with several thousands entries (almost 5000 for the kernel-default package). That produces a very long table which takes long time to parse and display in the UI.

    The solution is to limit the maximum number of displayed items in the UI. You cannot easily read that very long text anyway, for such a long text you would need some search functionality which the YaST UI does not provide.

    Finding the limit, that magic number, was not easy as we want to be backward compatible and display as much as possible but still avoid that pathological cases with a huge list.

  • openSUSE Tumbleweed Users Get Latest Mesa 17.1.3 Release for Better Gaming, More

    It's been only a week since our last report on the latest package updates that landed in the stable repositories of the openSUSE Tumbleweed operating system, and Douglas DeMaio is back with some fresh info.

    According to his report, only three snapshots saw the light of day since last week, but they brought some major package updated to the openSUSE Tumbleweed rolling distribution. First off, the graphics stack was updated to the latest Mesa 17.1.3 3D Graphics Library, which should add an extra layer of performance improvements for better gaming with AMD Radeon or Intel GPUs.

  • GStreamer, Mesa Packages Updated in Tumbleweed

    Three openSUSE Tumbleweed snapshots this week brought a few major release packages and a clear example for how the automated testing tool openQA can prevents a snapshot from being released.

    The unicode character map Gucharmap, which uses the gtk+ toolkit and runs on any platform that gtk+ supports, was updated to version 10.0.0 in the repositories in the 20170625 snapshot. The GNOME project updated translations and support of editors like Bluefish as well as many others. Other major release were also in the 20170625 snapshot. An update of net-tools to version 2.0 dropped the network statistics (netstat) Extended Internet Daemon (xinetd) service to phase out xinetd. Users of the proc file-system get cgroup namespaces with the arrival of the psmisc 23.0 package.

openSUSE Leap Is Now 99.9% Enterprise Distribution

Filed under
SUSE

Two years ago when openSUSE decided to move the base of openSUSE Leap to SUSE Linux Enterprise (SLE), they were entering uncharted territory. SLE is a tightly controlled enterprise ship that runs on mission critical systems. On the other hand openSUSE has been a community-driven project that, despite sponsorship from SUSE, is relatively independent.

It became clear, though, that moving to SLE source code would solve many problems for both members of the SUSE family. SLE would get a platform from where it can borrow the latest fully tested packages, and openSUSE Leap would get enterprise grade code base to move into CentOS and Ubuntu territory. SLE and openSUSE created a symbiotic relationship in which they were pulling content from each other.

Events: FOSDEM Samba Talks, USENIX Enigma, LCA (linux.conf.au) and FAST18

  • Authentication and authorization in Samba 4
    Volker Lendecke is one of the first contributors to Samba, having submitted his first patches in 1994. In addition to developing other important file-sharing tools, he's heavily involved in development of the winbind service, which is implemented in winbindd. Although the core Active Directory (AD) domain controller (DC) code was written by his colleague Stefan Metzmacher, winbind is a crucial component of Samba's AD functionality. In his information-packed talk at FOSDEM 2018, Lendecke said he aimed to give a high-level overview of what AD and Samba authentication is, and in particular the communication pathways and trust relationships between the parts of Samba that authenticate a Samba user in an AD environment.
  • Two FOSDEM talks on Samba 4
    Much as some of us would love never to have to deal with Windows, it exists. It wants to authenticate its users and share resources like files and printers over the network. Although many enterprises use Microsoft tools to do this, there is a free alternative, in the form of Samba. While Samba 3 has been happily providing authentication along with file and print sharing to Windows clients for many years, the Microsoft world has been slowly moving toward Active Directory (AD). Meanwhile, Samba 4, which adds a free reimplementation of AD on Linux, has been increasingly ready for deployment. Three short talks at FOSDEM 2018 provided three different views of Samba 4, also known as Samba-AD, and left behind a pretty clear picture that Samba 4 is truly ready for use. I will cover the first two talks in this article, and the third in a later one.
  • A report from the Enigma conference
    The 2018 USENIX Enigma conference was held for the third time in January. Among many interesting talks, three presentations dealing with human security behaviors stood out. This article covers the key messages of these talks, namely the finding that humans are social in their security behaviors: their decision to adopt a good security practice is hardly ever an isolated decision. Security conferences tend to be dominated by security researchers demonstrating their latest exploits. The talks are attack-oriented, they keep a narrow focus, and usually they close with a dark outlook. The security industry has been doing security conferences like this for twenty years and seems to prefer this format. Yet, if you are tired of this style, the annual USENIX Enigma conference is a welcome change of pace. Most of the talks are defense-oriented, they have a horizon going far beyond technology alone, and they are generally focused on successful solutions.
  • DIY biology
    A scientist with a rather unusual name, Meow-Ludo Meow-Meow, gave a talk at linux.conf.au 2018 about the current trends in "do it yourself" (DIY) biology or "biohacking". He is perhaps most famous for being prosecuted for implanting an Opal card RFID chip into his hand; the Opal card is used for public transportation fares in Sydney. He gave more details about his implant as well as describing some other biohacking projects in an engaging presentation. Meow-Meow is a politician with the Australian Science Party, he said by way of introduction; he has run in the last two elections. He founded BioFoundry, which is "Australia's first open-access molecular biology lab"; there are now two such labs in the country. He is also speaks frequently as "an emerging technology evangelist" for biology as well as other topics.
  • Notes from FAST18

    I attended the technical sessions of Usenix's File And Storage Technology conference this week. Below the fold, notes on the papers that caught my attention.

Security: Vista10 and uTorrent Holes Found by Google

  • Google drops new Edge zero-day as Microsoft misses 90-day deadline

    Google originally shared details of the flaw with Microsoft on 17 November 2017, but Microsoft wasn’t able to come up with a patch within Google’s non-negotiable “you have 90 days to do this” period.

  • Google Goes Public with Another Major Windows 10 Bug
    After revealing an Edge browser vulnerability that Microsoft failed to fix, Google is now back with another disclosure, this time aimed at Windows 10 Fall Creators Update (version 1709), but potentially affecting other Windows versions as well. James Forshaw, a security researcher that’s part of Google’s Project Zero program, says the elevation of privilege vulnerability can be exploited because of the way the operating system handles calls to Advanced Local Procedure Call (ALPC). This means a standard user could obtain administrator privileges on a Windows 10 computer, which in the case of an attack, could eventually lead to full control over the impacted system. But as Neowin noted, this is the second bug discovered in the same function, and both of them, labeled as 1427 and 1428, were reported to Microsoft on November 10, 2017. Microsoft said it fixed them with the release of the February 2018 Patch Tuesday updates, yet as it turns out, only issue 1427 was addressed.
  • uTorrent bugs let websites control your computer and steal your downloads

    The vulnerabilities, according to Project Zero, make it possible for any website a user visits to control key functions in both the uTorrent desktop app for Windows and in uTorrent Web, an alternative to desktop BitTorrent apps that uses a web interface and is controlled by a browser. The biggest threat is posed by malicious sites that could exploit the flaw to download malicious code into the Windows startup folder, where it will be automatically run the next time the computer boots up. Any site a user visits can also access downloaded files and browse download histories.

  • BitTorrent Client uTorrent Suffers Security Vulnerability (Updated)

    BitTorrent client uTorrent is suffering from an as yet undisclosed vulnerability. The security flaw was discovered by Google security researcher Tavis Ormandy, who previously said he would reveal a series of "remote code execution flaws" in torrent clients. BitTorrent Inc. has rolled out a 'patch' in the latest Beta release and hopes to fix the stable uTorrent client later this week.

KDE Says Its Next Plasma Desktop Release Will Start a Full Second Faster

According to the developer, the upcoming KDE Plasma 5.13 desktop environment release will start a full second faster than previous versions because of the removal of the QmlObjectIncubationController component, which apparently slowed down the entire desktop, and promises to let users pin apps on the panel that contain spaces in their desktop file names. Goodies are also coming to the upcoming KDE Applications 18.04 software suite this spring, which makes creating of new files with the Dolphin file manager instantaneous, improves drag-and-drop support from Spectacle to Chromium, and lets users configure the Gwenview image viewer to no longer display the image action buttons on thumbnails when they hover with the mouse cursor over them.
