  • 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.

  • Easily speed up CI by reducing download size

    Every time a CI pipeline runs on GitLab, it downloads the git repository for your project. Often, pipeline jobs are set up to make further downloads (of dependencies or subprojects), which are also run on each job.

  • What you need to know about automation testing in CI/CD

    Test automation means focusing continuously on detecting defects, errors, and bugs as early and quickly as possible in the software development process. This is done using tools that pursue quality as the highest value and are put in place to ensure quality—not just pursue it. One of the most compelling features of a continuous integration/continuous delivery (CI/CD) solution (also called a DevOps pipeline) is the opportunity to test more frequently without burdening developers or operators with more manual work. Let's talk about why that's important.

  • Generics for Go

    The Go programming language was first released in 2009, with its 1.0 release made in March 2012. Even before the 1.0 release, some developers criticized the language as being too simplistic, partly due to its lack of user-defined generic types and functions parameterized by type. Despite this omission, Go is widely used, with an estimated 1-2 million developers worldwide. Over the years there have been several proposals to add some form of generics to the language, but the recent proposal written by core developers Ian Lance Taylor and Robert Griesemer looks likely to be included in a future version of Go. [...] Generics, also known as "parameterized types" or "parametric polymorphism", are a way to write code or build data structures that will work for any data type; the code or data structure can be instantiated to process each different data type, without having to duplicate code. They're useful when writing generalized algorithms like sorting and searching, as well as type-independent data structures like trees, thread-safe maps, and so on. For example, a developer might write a generic min() function that works on all integer and floating-point types, or create a binary tree that can associate a key type to a value type (and work with strings, integers, or user-defined types). With generics, you can write this kind of code without any duplication, and the compiler will still statically check the types.

  • Fixing a common antipattern when loading translations in Qt

    I’m a Polish guy working with computers, mostly on Windows. However, the lingua franca of the IT industry is English, so every time I see a tutorial for some dev tool, it’s in that language. To lessen the burden of decoding which menu entry in the tutorial corresponds to which menu entry on my PC I decided to run the system with an English display language. I still want the rest of the i18n-related stuff (date format, keyboard, currency etc.) to be in Polish however. [...] As you can see, Thunderbird and Windows Settings show up in English but Qt Linguist is encrypted with some overengineered Slavic cipher (aka Polish language). What I further noticed, is that this incorrect language selection is particularly prevalent in Qt-based applications. Subsequent digging revealed that this antipattern is widespread in Qt world, see the relevant GitHub search (requires login).

  • Android 10 has the fastest update rate ever, hits 16% of users in 10 months

    Google today dropped a blog post detailing its progress on improving the Android ecosystem's update speed. The company has been hard at work for the past few years modularizing Android, with the hope that making Android easier to update would result in device manufacturers pushing out updates faster. Google's efforts have been paying off, with the company announcing Android 10 has had the fastest rollout ever. The last few versions of Android have each brought a major improvement to Android's update system. Android 8 introduced Project Treble, which separated the OS from the hardware support, enabling easier porting of Android across devices. In Android 9 Pie, Google completed its work on Treble and started publishing Generic System Images (GSIs): drop-in versions of Android that work on any Project Treble-compatible device. Android 10 introduced Project Mainline and the new APEX file type designed for updatable lower-level system components, delivered through the Play Store. Google's stats show that all this work is actually improving the ecosystem. "Thanks to these efforts," Google writes, "the adoption of Android 10 has been faster than any previous versions of Android. Android 10 was running on 100 million devices 5 months post launch—28% faster than Android Pie."

Servers: Kubernetes, MicroK8s and Ubuntu

  • What’s up with the Kubernetes ecosystem

    This week’s acquisition of Rancher Labs by the veteran enterprise Linux firm SUSE neatly illustrates the growing momentum of container-based application deployment. It also underlines the importance of Kubernetes as the orchestration tool of choice for managing all those containers. So, what does this latest move mean for the broader Kubernetes ecosystem? When containers first garnered corporate attention six or seven years ago, Docker and its tools were the centre of attention. But the focus soon shifted to management frameworks capable of automating the deployment and scaling of containers, and Kubernetes, developed by Google from technology used in its cloud platform, quickly won out. Like many open source tools, Kubernetes has its share of rough edges and does not necessarily provide all the capabilities that users need to build a functioning container-based infrastructure. Companies such as Rancher sprang forth to provide a complete software stack built around Kubernetes for those who didn’t want to build it all themselves.
