  • Openlab: what it is and why it matters

    Six months on from its announcement at Openstack Summit Sydney in late 2017, community testing project OpenLab is in full swing.

    OpenLab was initially formed by Intel, Huawei and the OpenStack foundation as a community-led project for improving SDK support and also introducing other platforms like Kubernetes and Cloud Foundry to the Openstack environment. Ultimately the idea is to improve usability in hybrid and multi-cloud environments.

    Melvin Hillsman sits on the governance board along with Dr Yih Leong Sun of Intel and Chris Hoge from the Foundation. Hillsman moved from Rackspace to Huawei to work specifically on the project.

    "The reason we think Openlab is important is, basically, Openstack for some time has been very specific about testing and integration for Openstack services, focusing only on the projects started at Openstack," Hillsman tellsComputerworld UK at the Openstack Vancouver Summit. "It's been working very well, it's a robust system. But for me as a person in the user community - my getting involved in Openstack was more on the operator-user side.

  • Open source innovation tips for the customer-driven economy

    New technologies, ranging from big data and blockchain to 3D printing, are giving rise to new opportunities and challenges for companies today. To stay competitive, organizations need to become more intelligent, customer-centric, and increasingly agile to cope with changing business demands.

    The worry for many companies which are trying to innovate is that while the speed and scope of applications are expanding rapidly, the variety and complexity of technology is increasing simultaneously, putting pressure on their IT infrastructure.

    Speaking at the SUSE Expert Days 2018 held in Singapore recently, Dr Gerald Pfeifer, VP of Products and Technology Program, SUSE, told attendees that these prevailing trends have come together to make Open Source the primary engine for business innovation.

  • Qualcomm is able to release the Snapdragon 845 source code in 6 weeks

    Qualcomm‘s latest high-end system-on-chip, the Qualcomm Snapdragon 845, was announced at the Snapdragon Tech Summit back in December. The chipset offers 4 Kryo 385 (A75 “performance”) and 4 Kryo 385 (A55 “efficiency”) CPU cores, the latest Adreno 630 GPU, the Spectra 280 ISP, the Hexagon 685 DSP, the Snapdragon X20 LTE modem, and a new Secure Processing Unit (SPU). The Snapdragon 845 SoC is a powerhouse in benchmarks and it is already available in devices like the Samsung Galaxy S9/S9+, Xiaomi Mi Mix 2S, and the OnePlus 6. Developers on our forums have been itching to get their hands on a device with Qualcomm’s latest and greatest, but there’s just one thing that has made some developers worry about the future of development on the platform: The lack of publicly available source code for the kernel, HALs, framework branches, and more on the CodeAurora Forums.

  • Kata Containers 1.0 Released, Formerly Intel Clear Containers

    Back in December was the announcement of Intel's Clear Containers being spun into a new project called Kata Containers in collaboration with other organizations. Kata Containers has now reached their version 1.0 milestone.

    Kata Containers 1.0 is now available for this container technology designed for offering a secure and scalable container experience built atop Intel VT technology.

  • What's new in OpenStack?

    As OpenStack Foundation Chief Operating Officer Mark Collier referenced in his opening keynote, the uses which OpenStack is seeing today expand far beyond what most who were involved in the early days of the project could have ever imagined. While OpenStack started out primarily in the traditional data center and found many large-scale users, particularly in the telecommunications industry, who were using it to manage huge installations of traditional x86 server hardware, the flexibility of OpenStack has today allowed it to thrive in many other environments and use cases.

    Today, we see OpenStack powering everything from academic and research projects to media and gaming services, from online retail and e-commerce to manufacturing and industrial applications, and from finance to healthcare. OpenStack is found in all of these different places not just because it is cheaper than using the public cloud, not just because it makes compliance with various regulations easier, but because its open source code makes it flexible to all sort of different situations.

  • Should Red Hat Buy or Build a Database?

    For a decade, at least, observers of the company have speculated about whether Red Hat would or should enter the database market. The primary argument, one made in this space eight years ago, has historically been that Red Hat is de facto leaving potential dollars on the table by limiting itself to operating platform and immediately adjacent markets. In a more recent piece, analyst Krishnan Subramanian adds that Red Hat is at risk because databases represent a control point, one that the company is effectively ceding to competitors such as AWS or Microsoft.

  • Tidelift Raises $15M Series A From General Catalyst, Foundry, & Others

    This morning Tidelift, a startup focused on helping developers work with open source technology, announced that it has closed a $15 million Series A round of funding co-led by General Catalyst, Foundry, and Matthew Szulik, the former CEO of Red Hat, a public open source-centered technology company.

    The subscription-powered startup has an interesting business model which we’ll dive into shortly, but it’s worth noting that the open source space as a whole is quite active. It’s something that Crunchbase News covered last year, describing how startups working with open source software have enjoyed a dramatic rise in investor interest.

    That puts Tidelift in the midst of a trend.

  • Tidelift lands $15M to deliver professional open-source support

    Tidelift Inc. is raising $15 million as it looks to boost its unique open-source software model that sees companies pay for professional support of their favorite projects, allowing those that maintain them to get compensated too.

    The Series A round was led by the investment firms General Catalyst and Foundry Group, as well as former Red Hat Inc. Chairman and Chief Executive Matthew Szulik. The company was able to attract the investment after coming up with a novel idea for maintaining the most popular open-source software projects in a way that benefits both the users and those who help to create them.

    It works like this: Companies pay a subscription fee that entitles them to professional-grade support, similar to the kind of commercial subscriptions offered by firms such as Red Hat, Cloudera Inc. and Docker Inc. A part of these fees are then used to pay the developers who maintain the software. The net result, at least in theory, is that everyone is happy, as companies enjoy the benefits of professional support at lower rates than they might expect from an established firm, and the developers of the software are finally rewarded for their efforts.

  • Ubuntu's Shuttleworth Creates Controversy with OpenStack Summit Vancouver Keynote

    The OpenStack Foundation is facing a bit of drama and controversy as it deals with issues related to a keynote delivered by Ubuntu Linux founder, Mark Shuttleworth at the OpenStack Summit here on May 21.

    Typically the OpenStack Foundation posts videos of all its session online within 24 hours, but with the Shuttleworth keynote, the video was apparently posted and then promptly removed. During his keynote, Shuttleworth took direct aim at his OpenStack competitor Red Hat, which apparently made some people in the OpenStack Summit community uncomfortable.

Finally: Historic Eudora email code goes open source

TuxMachines - Wed, 2018-05-23 20:21

The source code to the Eudora email client is being released by the Computer History Museum, after five years of discussion with the IP owner, Qualcomm.

The Mac software was well loved by early internet adopters and power users, with versions appearing for Palm, Newton and Windows. At one time, the brand was so synonymous with email that Lycos used Eudora to brand its own webmail service. As the Mountain View, California museum has noted, "It’s hard to overstate Eudora’s popularity in the mid-1990s."

gnome15 dead? G910 G-Keys Support

Reddit - Wed, 2018-05-23 19:25

Hey guys, I just bought me a new G910 Keyboard, and was looking around trying to find a way to use the G-Keys on it. I've looked just about everywhere, I even read about gnome15 and what it was. But from what it looks like some of their stuff is dead. I've even tried to compile from source using their website, and their instructions (along with the instructions from the github page that it references) are messed up and wrong. (There is literally no configure file. and there's no buildtools bash script file) Can you guys give me some advise on how to make the GKeys actually work? I'd like to get the M-Keys working eventually too. But that's in the future.

Any still-maintained distributions that use glibc 2.11 or lower?

Reddit - Wed, 2018-05-23 19:23

Are there any Linux distributions left that target glibc 2.11 or older, and that are still maintained? I'm asking this out of curiousity, as well as an extreme attention to portability for my Linux applications.

From a brief survey of distributions, most things like Debian, Arch, and Slackware target glibc 2.24 or similar. RHEL7 appears to be one of the few remaining distributions to target glibc 2.17, and RHEL6 targets 2.12.

If someone can point out other distributions that do rely on glibc 2.12, 2.11, or earlier, then I can think about how to backport my applications for those systems. Otherwise, I guess it's safe to mostly target 2.24, and 2.17 for RHEL's. That would give me a better sense of where to focus my efforts for software portability.

Ubuntu 18.04 power off and Firefox 60.0.1

Reddit - Wed, 2018-05-23 19:06

I am using Ubuntu 18.04 + Firefox 60.0.1 and whenever I turn my computer off without closing Firefox, Firefox will complain upon the next startup that it was not closed properly.

Does anybody else have the same issue and does anybody know how to fix it? It's not really a huge issue, but it is kind of annoying.

Security Leftovers, Mostly 'Spectre' and 'Meltdown' Related

TuxMachines - Wed, 2018-05-23 19:04
  • More Meltdown/Spectre Variants
  • Spectre V2 & Meltdown Linux Fixes Might Get Disabled For Atom N270 & Other In-Order CPUs

    There's a suggestion/proposal to disable the Spectre Variant Two and Meltdown mitigation by default with the Linux kernel for in-order CPUs.

    If you have an old netbook still in use or the other once popular devices powered by the Intel Atom N270 or other in-order processors, there may be some reprieve when upgrading kernels in the future to get the Spectre/Meltdown mitigation disabled by default since these CPUs aren't vulnerable to attack but having the mitigation in place can be costly performance-wise.

  • Linux 4.17 Lands Initial Spectre V4 "Speculative Store Bypass" For POWER CPUs

    Following yesterday's public disclosure of Spectre Variant Four, a.k.a. Speculative Store Bypass, the Intel/AMD mitigation work immediately landed while overnight the POWER CPU patch landed.

  • New Variant Of Spectre And Meltdown CPU Flaw Found; Fix Affects Performance
  • Ubuntu 18.04 LTS Gets First Kernel Update with Patch for Spectre Variant 4 Flaw

    Canonical released the first kernel security update for its Ubuntu 18.04 LTS (Bionic Beaver) operating system to fix a security issue that affects this release of Ubuntu and its derivatives.

    As you can imagine, the kernel security update patches the Ubuntu 18.04 LTS (Bionic Beaver) operating system against the recently disclosed Speculative Store Buffer Bypass (SSBB) side-channel vulnerability, also known as Spectre Variant 4 or CVE-2018-3639, which could let a local attacker expose sensitive information in vulnerable systems.

  • RHEL and CentOS Linux 7 Receive Mitigations for Spectre Variant 4 Vulnerability

    As promised earlier this week, Red Hat released software mitigations for all of its affected products against the recently disclosed Spectre Variant 4 security vulnerability that also affects its derivatives, including CentOS Linux.

    On May 21, 2018, security researchers from Google Project Zero and Microsoft Security Response Center have publicly disclosed two new variants of the industry-wide issue known as Spectre, variants 3a and 4. The latter, Spectre Variant 4, is identified as CVE-2018-3639 and appears to have an important security impact on any Linux-based operating system, including all of its Red Hat's products and its derivatives, such as CentOS Linux.
