  • Join SIG Scalability and Learn Kubernetes the Hard Way

    Contributing to SIG Scalability is a great way to learn Kubernetes in all its depth and breadth, and the team would love to have you join as a contributor. I took a look at the value of learning the hard way and interviewed the current SIG chairs to give you an idea of what contribution feels like.

  • Kong Ingress Controller and Service Mesh: Setting up Ingress to Istio on Kubernetes

    Kubernetes has become the de facto way to orchestrate containers and the services within services. But how do we give services outside our cluster access to what is within? Kubernetes comes with the Ingress API object that manages external access to services within a cluster.

    Ingress is a group of rules that will proxy inbound connections to endpoints defined by a backend. However, Kubernetes does not know what to do with Ingress resources without an Ingress controller, which is where an open source controller can come into play. In this post, we are going to use one option for this: the Kong Ingress Controller. The Kong Ingress Controller was open-sourced a year ago and recently reached one million downloads. In the recent 0.7 release, service mesh support was also added.

  • Kubernetes 1.18 release candidate available for testing

    The latest release of Kubernetes is now available for download and experimentation, with the MicroK8s Kubernetes 1.18 release candidate.

    The easiest, fastest way to get the latest Kubernetes is to install MicroK8s on your machine.

  • High Performance Computing in the Age of Coronavirus

    2020 has suddenly become the year of the coronavirus. In order to slow transmissions, save lives and dampen the economic impact of this frightful virus – governments, medical professionals, research institutes are racing around the clock to transform plans into action. Speed is key – that’s where high performance computing comes in.

    Here are a few profiles of organizations that are stepping up to the front lines of this new bio-war:

  • Stacking Up Arm Server Chips Against X86

    It is pretty clear at this point that there is going to be a global recession thanks to the coronavirus outbreak. Maybe it will be a V-shaped recession that falls fast and recovers almost as fast, and maybe it will be a sharp drop and a much more prolonged climb back to normalcy. As we have pointed out before, we think that IT technology transitions are accelerated by such trying times, and this could happen starting soon. There is no doubt that companies are going to be even more aggressive in measuring the performance per dollar and performance per watt on every piece of hardware that will still need to go into datacenters in the coming days, weeks, and months.

    As far as servers go, AMD, with its Epyc processors, is going to perhaps be the biggest beneficiary because it is the easiest drop-in replacement for the much more expensive Xeon SP processors from Intel. And while the Arm server chip upstarts, Ampere Computing and Marvell, were not planning for a global pandemic when they timed the launches of their chips on their roadmaps, they may be among the beneficiaries of the budget tightening that will no doubt start at most companies – if it hasn’t already. They would do well to get their chip samples ramped and products into the field as soon as possible.

    We have reviewed the upcoming “Quicksilver” Altra processor from Ampere Computing and its future roadmap two weeks ago and also reviewed the upcoming “Triton” ThunderX3 processor from Marvell and its future roadmap this week. And now we are going to go through the performance and price/performance competitive analysis that these two chip makers have done as they talk about their impending server chips.

LibreOffice: LibreOffice Macro Team, Writer and Impress

  • LibreOffice Macro Team: progress report

    Macros help users to automate common tasks in LibreOffice. In September 2019 we announced a new team in our community to work on macro support. A progress report was published in November 2019, so let’s review everything that happened since then. If you are interested in contributing to the macro team (development, testing or documentation), we’d love to hear from you – please send an email to and we’ll get in touch.

  • Padded numbering in Writer, part 2

    I already posted about the start of padded numbering support in Writer, there the focus was to insert 0 characters to pad up the result to 2 characters. Let’s see how that got extended in the recent past… First, thanks Nicolas Christener who made this work by Collabora possible.
