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.

5 tips for making documentation a priority in open source projects

Open source software is now mainstream; long gone are the days when open source projects attracted developers alone. Nowadays, users across numerous industries are active consumers of open source software, and you can't expect everyone to know how to use the software just by reading the code. Even for developers (including those with plenty of experience in other open source projects), good documentation serves as a valuable onboarding tool when people join a community. People who are interested in contributing to a project often start by working on documentation to get familiar with the project, the community, and the community workflow. Read more

5 reasons to run Kubernetes on your Raspberry Pi homelab

There's a saying about the cloud, and it goes something like this: The cloud is just somebody else's computer. While the cloud is actually more complex than that (it's a lot of computers), there's a lot of truth to the sentiment. When you move to the cloud, you're moving data and services and computing power to an entity you don't own or fully control. On the one hand, this frees you from having to perform administrative tasks you don't want to do, but, on the other hand, it could mean you no longer control your own computer. This is why the open source world likes to talk about an open hybrid cloud, a model that allows you to choose your own infrastructure, select your own OS, and orchestrate your workloads as you see fit. However, if you don't happen to have an open hybrid cloud available to you, you can create your own—either to help you learn how the cloud works or to serve your local network. Read more

  • Holger Levsen: DebConf7

    DebConf7 was also special because it had a very special night venue, which was in an ex-church in a rather normal building, operated as sort of community center or some such, while the old church interior was still very much visible as in everything new was build around the old stuff. And while the night venue was cool, it also ment we (video team) had no access to our machines over night (or for much of the evening), because we had to leave the university over night and the networking situation didn't allow remote access with the bandwidth needed to do anything video. The night venue had some very simple house rules, like don't rearrange stuff, don't break stuff, don't fix stuff and just a few little more and of course we broke them in the best possible way: Toresbe with the help of people I don't remember fixed the organ, which was broken for decades. And so the house sounded in some very nice new old tune and I think everybody was happy we broke that rule.

  • Podcast: COBOL development on the mainframe

    Nic reached out when COBOL hit the news this spring to get some background on what COBOL is good for historically, and where it lives in the modern infrastructure stack. I was able to talk about the basics of COBOL and the COBOL standard, strengths today in concert with the latest mainframes, and how COBOL back-end code is now being integrated into front ends via intermediary databases and data-interchange formats like JSON, which COBOL natively supports.

  • What I learned while teaching C programming on YouTube

    The act of breaking something down in order to teach it to others can be a great way to reacquaint yourself with some old concepts and, in many cases, gain new insights. I have a YouTube channel where I demonstrate FreeDOS programs and show off classic DOS applications and games. The channel has a small following, so I tend to explore the topics directly suggested by my audience. When several subscribers asked if I could do more videos about programming, I decided to launch a new video series to teach C programming. I learned a lot from teaching C, and in the process, I came across some meaningful takeaways I think others will appreciate. Make a plan For my day job, I lead training and workshops to help new and emerging IT leaders develop new skills. Outside of regular work, I also enjoy teaching as an adjunct professor. So I'm very comfortable constructing a course outline and designing a curriculum. That's where I started. If you want to teach a subject effectively, you can't just wing it. Start by writing an outline of what topics you want to cover and figure out how each new topic will build on the previous ones. The "building block" method of adding new knowledge is key to an effective training program.

  • Google Engineers Propose "Machine Function Splitter" For Faster Performance

    Google engineers have been working on the Machine Function Splitter as their means of making binaries up to a few percent faster thanks to this compiler-based approach. They are now seeking to upstream the Machine Function Splitter into LLVM. The Machine Function Splitter is a code generation optimization pass for splitting code functions into hot and cold parts. They are doing this stemming from research that in roughly half of code functions that more than 50% of the code bytes are never executed but generally loaded into the CPU's data cache.

  • Modernize network function development with this Rust-based framework

    The world of networking has undergone monumental shifts over the past decade, particularly in the ongoing move from specialized hardware into software defined network functions (NFV) for data plane1 and packet processing. While the transition to software has fashioned the rise of SDN (Software-defined networking) and programmable networks, new challenges have arisen in making these functions flexible, efficient, easier to use, and fast (i.e. little to no performance overhead). Our team at Comcast wanted to both leverage what the network does best, especially with regards to its transport capacity and routing mechanisms, while also being able to develop network programs through a modern software lens—stressing testing, swift iteration, and deployment. So, with these goals in mind, we developed Capsule, a new framework for network function development, written in Rust, inspired by Berkeley's NetBricks research, and built-on Intel's Data Plane Development Kit (DPDK).
