Reviews

When it comes to new laptops for the summer of 2018 that are Linux-friendly, the latest-generation Dell XPS 13 with Intel Kabylake-R processor ranks high on that list. Recent in upgrading my main production workstation, I decided to go with the Dell XPS 13 9370 while using Fedora Workstation 28 and it's been a phenomenal combination. Here are my thoughts on the current Dell XPS 13 as well as some benchmarks and other information.

Filed under
Ubuntu

One of the most attractive things about the forthcoming Ubuntu 18.10 operating system, due for release later this fall on October 18, 2018, is its new look and feel, which is provided by the so-called Communitheme that was recently renamed as Yaru, a system-wide theme for Ubuntu Desktop.

As part of this community initiative, Ubuntu 18.10 will get a brand-new look and feel that will make the popular computer operating system more modern, more accessible, and more attractive. And, today we finally have a first look at the Yaru theme on the current Ubuntu 18.10 (Cosmic Cuttlefish) development release.

  • How to be the lazy sysadmin

    The job of a Linux SysAdmin is always complex and often fraught with various pitfalls and obstacles. Ranging from never having enough time to do everything, to having the Pointy-Haired Boss (PHB) staring over your shoulder while you try to work on the task that she or he just gave you, to having the most critical server in your care crash at the most inopportune time, problems and challenges abound. I have found that becoming the Lazy Sysadmin can help.

  • What's in a container image: Meeting the legal challenges

    Container technology has, for many years, been transforming how workloads in data centers are managed and speeding the cycle of application development and deployment.

    In addition, container images are increasingly used as a distribution format, with container registries a mechanism for software distribution. Isn't this just like packages distributed using package management tools? Not quite. While container image distribution is similar to RPMs, DEBs, and other package management systems (for example, storing and distributing archives of files), the implications of container image distribution are more complicated. It is not the fault of container technology itself; rather, it's because container distribution is used differently than package management systems.

  • IBM & Google Launch 'Istio' Cloud Software, but Amazon & Microsoft Skip the Party

    Istio, an open source project backed by IBM, Google, Red Hat and others for connecting, managing and securing Kubernetes containers, hits version 1.0 Tuesday. But can Istio become ubiquitous without support from market leaders Amazon Web Services and Microsoft?

    Istio, also backed by Lyft Inc. and Pivotal , is a "service mesh," picking up where Kubernetes leaves off. Kubernetes provides orchestration to run multiple containers, manage their lifecycle, keep them available and scale them up and down as needed. Istio is software for managing how containers interact with each other.

  • The Istio service mesh hits version 1.0
  • What is Istio? The latest open source project out of Google
  • Istio sets sail as Red Hat renovates OpenShift container ship

    Red Hat is celebrating the 1.0 release of Istio, the open source microservices management project, and the arrival of version 3.10 of its OpenShift software container platform.

    Istio's 1.0 release received mention at Google Cloud Next last week, but the official bits are expected on Tuesday. The software serves as a management mechanism for distributed microservices, providing capabilities like traffic management, service identity and security, policy enforcement and telemetry among apps running across multiple Kubernetes clusters and hosts.

  • IBM, Google, Red Hat push Istio to 1.0 release

    IBM launched Istio along with Google Cloud and Lyft a little more than a year ago. The goal of Istio is to give developers a vendor-neutral way to connect, secure and manage networks of various microservices.

    Managing microservices is a critical issue since enterprises are increasingly built on them. By breaking services and applications into smaller parts developers can be more agile. The issue is that managing various microservices requires a good bit of choreography.

Story of GNOME Shell Extensions

Filed under
GNOME

A long time ago (exactly 10 years ago) it was decided that the the shell for GNOME would be written in JavaScript. GNOME 3 was still looking for its new face, a lot of UI experimentation was taking place, and JavaScript looked like the best candidate for it. Moreover it was a popular language on the web, so barriers to entry for new contributors would be significantly lowered.

When you have the shell written in JavaScript you can very easily patch it and alter its look and behaviour. And that’s what people started doing. Upstream was not very keen to officially support extensions due to their nature: they’re just hot patching the GNOME Shell code. They have virtually unlimited possibilities in changing look and behaviour, but also in introducing instability.

  • Secure NTP with NTS

    Many computers use the Network Time Protocol (NTP) to synchronize their system clocks over the internet. NTP is one of the few unsecured internet protocols still in common use. An attacker that can observe network traffic between a client and server can feed the client with bogus data and, depending on the client’s implementation and configuration, force it to set its system clock to any time and date. Some programs and services might not work if the client’s system clock is not accurate. For example, a web browser will not work correctly if the web servers’ certificates appear to be expired according to the client’s system clock. Use Network Time Security (NTS) to secure NTP. Fedora 331 is the first Fedora release to support NTS. NTS is a new authentication mechanism for NTP. It enables clients to verify that the packets they receive from the server have not been modified while in transit. The only thing an attacker can do when NTS is enabled is drop or delay packets. See RFC8915 for further details about NTS. NTP can be secured well with symmetric keys. Unfortunately, the server has to have a different key for each client and the keys have to be securely distributed. That might be practical with a private server on a local network, but it does not scale to a public server with millions of clients. NTS includes a Key Establishment (NTS-KE) protocol that automatically creates the encryption keys used between the server and its clients. It uses Transport Layer Security (TLS) on TCP port 4460. It is designed to scale to very large numbers of clients with a minimal impact on accuracy. The server does not need to keep any client-specific state. It provides clients with cookies, which are encrypted and contain the keys needed to authenticate the NTP packets. Privacy is one of the goals of NTS. The client gets a new cookie with each server response, so it doesn’t have to reuse cookies. This prevents passive observers from tracking clients migrating between networks.

  • Role of Training and Certification at the Linux Foundation

    Open source allows anyone to dip their toes in the code, read up on the documentation, and learn everything on their own. That’s how most of us did it, but that’s just the first step. Those who want to have successful careers in building, maintaining, and managing IT infrastructures of companies need more structured hands-on learning with real-life experience. That’s where Linux Foundation’s Training and Certification unit enters the picture. It helps not only greenhorn developers but also members of the ecosystem who seek highly trained and certified engineers to manage their infrastructure. Swapnil Bhartiya sat down with Clyde Seepersad, SVP and GM of Training and Certification at the Linux Foundation, to learn more about the Foundation’s efforts to create a generation of qualified professionals.

  • Integer Scaling To Come With Linux 5.11 For Intel Graphics Driver - Phoronix

    Going back more than a year there have been Intel "i915" kernel graphics driver patches implementing integer mode scaling support while finally for Linux 5.11 in early 2021 the support will have landed. Intel added integer mode scaling to their Windows graphics driver back in 2019 to provide better clarity when upscaling games (particularly pixel art type content) and other software. The Linux patches materialized in September 2019 for nearest-neighbor integer mode scaling and then seemingly forgotten about. The capability works with Gen11 / Ice Lake and newer.

  • Linux Support for Variable Refresh Rates On Gen12+ Intel GPUs Is On The Way - LinuxReviews

    Intel developer Manasi Navare has submitted a series of patches for the Linux kernel that brings support for variable refresh rates on Intel's latest graphics chips to the Linux kernels i915 driver. The feature is only enabled on Tiger Lake, Sapphire Rapids and newer Intel graphics chips. [...] You do not need a special "Freesync" monitor to use adaptive vertical synchronization, Freesync is just a marketing term used by AMD. The DisplayPort specification has included variable refresh rate (VRR) as an option feature since DP 1.4 and there are many monitors with support for it that are not marketed as "Freesync" or "gaming" monitors. Monitors that are marketed as "Freesync" support the standard DisplayPort VRR protocol so you don't need to use a AMD graphics card to get the benefits of a Freesync monitor. You will soon be able to use one of the very latest Intel CPU's with integrated graphics or one of Intel's upcoming dedicated graphics cards with Freesync monitors on Linux.

  • Salsa updated to GitLab 13.5

    Today, GitLab released the version 13.5 with several new features. Also Salsa got some changes applied to it. [...] It's been way over two years since we started to use Google Compute Engine (GCE) for Salsa. Since then, all the jobs running on the shared runners run within a n1-standard-1 instance, providing a fresh set of one vCPU and 3.75GB of RAM for each and every build. GCE supports several new instance types, featuring better and faster CPUs, including current AMD EPICs. However, as it turns out, GCE does not support any single vCPU instances for any of those types. So jobs in the future will use n2d-standard-2 for the time being, provinding two vCPUs and 8GB of RAM..

  • Firefox on Fedora with OpenH264 – Martin Stransky's Blog

    Firefox on Fedora which sits in the updates [F32][F31] right now comes with enabled OpenH264 Cisco decoder for video playback and fdk-aac-free used for audio decoding. It’s implemented by GMP (Gecko Media Plugin) API so the OpenH264 is not used through ffmpeg library but Firefox sandboxed interface, the same as Firefox uses for Widevine CDM plugin. The OpenH264 GMP video playback is a fallback solution when system ffmpeg is missing and internal ffvpx library can’t decode the stream, so ffmpeg from RPM Fusion is always a better alternative if you can install it. The video streams are decoded by system wide OpenH264 2.1.1 which is shipped by Fedora as mozilla-openh264 rpm package. Even if Mozilla OpenH264 (1.8.1) plugin is installed in your profile and claimed at about:plugins page, the Fedora system one is used.

  • Open Education and Artificial Scarcity in Hard Times

    The sudden move to remote education by universities this year has forced the inevitable: the move to an online education. While most universities won’t be fully remote, having course materials online was already becoming the norm before the COVID-19 pandemic, and this year it has become mandatory for millions of educators and students. As academia recovers from this crisis, and hopefully prepares for the next one, the choices we make will send us down one of two paths. We can move towards a future of online education which replicates the artificial scarcity of traditional publishing, or take a path which fosters an abundance of free materials by embracing the principles of open access and open education.

    The well-worn, hefty, out-of-date textbook you may have bought some years ago was likely obsolete the moment you had a reliable computer and an Internet connection. Traditional textbook publishers already know this, and tout that they have embraced the digital era and have ebooks and e-rentals available—sometimes even at a discount. Despite some state laws discouraging the practice, publishers try to bundle their digital textbooks into “online learning systems,” often at the expense of the student. However, the costs and time needed to copy and send thousands of the digital textbooks themselves is trivial compared to their physical equivalent. 

  • Hybrid open access risks limiting researchers’ publishing options

    In the case of the 34 Nature-branded journals, the first step is a “read and publish” deal with Germany’s Max Planck institutes, allowing affiliated researchers to both access the journals and to publish in them open access. The OA fee that Max Planck will pay is based on a cost of €9,500 (£8,600) per article. The publisher, Springer Nature, says that it is in discussions to allow authors worldwide to publish open access in Nature journals from next year.

    The UK alone spends more than £25 million on OA journal publishing annually, but the proportion that goes to large commercial publishers for OA in hybrid journals has increased year-on-year. The average cost for publishing in hybrid journals also continues to increase steadily.

    This trend has been evident since Springer Nature launched its leading OA journals, Nature Communications and Scientific Reports. In 2018 alone, these journals received more than £1.6 million from 30 UK research-intensive institutions. In 2019, Elsevier launched 100 new OA journals and the humanities publisher IEEE launched 13.
