• My exciting journey into Kubernetes’ history

  Choosing the right steps when working in the field of data science is truly no silver bullet. Most data scientists might have their custom workflow, which could be more or less automated, depending on their area of work. Using Kubernetes can be a tremendous enhancement when trying to automate workflows on a large scale. In this blog post, I would like to take you on my journey of doing data science while integrating the overall workflow into Kubernetes. The target of the research I did in the past few months was to find any useful information about all those thousands of GitHub issues and pull requests (PRs) we have in the Kubernetes repository. What I ended up with was a fully automated, in Kubernetes running Continuous Integration (CI) and Deployment (CD) data science workflow powered by Kubeflow and Prow. You may not know both of them, but we get to the point where I explain what they’re doing in detail. The source code of my work can be found in the kubernetes-analysis GitHub repository, which contains everything source code-related as well as the raw data. But how to retrieve this data I’m talking about? Well, this is where the story begins.

• Myriad X based AI accelerator module has a built-in 12MP, 4K camera

  Luxonis is crowdfunding an open source, $169 “megaAI” AI acceleration and camera module with an up to 4-TOPS Intel Myriad X VPU, a USB 3.0 port, and a 12-megapixel, 4K camera. When Luxonis launched its Intel Movidius Myriad X DepthAI AI acceleration module last November, an external 4K camera was optional. Now, Luxonis has gone to Crowd Supply to successfully launch a $169 megaAI module, which is like a DepthAI with an integrated 12-megapixel, 4K camera.

OSS and Other Leftovers

• Release notes for the Genode OS Framework 20.05

  Genode 20.05 takes our road map's focus on the consolidation and optimization of the framework and its API to heart. It contains countless of under-the-hood improvements, mostly on the account of vastly intensified automated testing, the confrontation of Genode with increasingly complex software stacks, and stressful real-world work loads. You will find this theme throughout the release notes below. The result of this overhaul is captured in the updated version of the Genode Foundations book (Section New revision of the Genode Foundations book). [...] Even though Genode is able to run on top of the Linux kernel since the very beginning, Linux was solely meant as a development vehicle.

• Genode OS 20.05 Adds Capability-Based Security Using SECCOMP, Drops Python 2 + Rust

  Version 20.05 of the Genode open-source operating system framework is now available with many improvements. Genode OS 20.05 contains various work particularly on the consolidation and optimization front. There is also better 64-bit Arm support, documentation improvements, and capability-based security using SECCOMP on Linux. Genode OS 20.05 has improvements to its consistent block encrypter, retired its Noux runtime environment, removed Rust support after no one has been maintaining its support in years, dropping Python 2 given its EOL status and Python 3 support being in good shape, MSI-X support on x86, and various other updates.

• Talk 9: big step forward for team calls, efficient work flows and open source back-end

  Nextcloud GmbH is glad to announce the upcoming major release of Nextcloud Talk that will include significant improvements for teams collaborating remotely, including easy document sharing with drag’n’drop, in-call collaborative document editing and significant modifications to facilitate calls with more participants. Together with this release, our partner Struktur AG makes the high-performance back-end available under the AGPL license. A first release candidate of Talk 9 is available today and the final release is expected in about two weeks. Most of the improvements in the area of performance and scalability have been backported to the stable Talk 8 series, making them available to users right now.

• COVID-19 Crisis: FOSS Responders Raises $115,000 To Support Community

  Conference cancellations have caused financial loss, unmet fundraising trajectories and missed business opportunities. For example, the Open Source Institute, the organisation that ratifies open source licences, has indicated that it needs $600,000 to meet its funding goals for 2020 while the Drupal Association has had to layoff employees after cancelling events and needs to fundraise $500,000.

• GNUnet Hacker Meeting 2020

  We are happy to announce that we will have a GNUnet Hacker Meeting from 17-21 of June 2020 taking place online. For more information see here.

• It’s Time to Get Back Into RSS

  A lot of people who were on the internet in the early 2000’s remember something called RSS. It stands for really simple syndication, and it allowed content creators to publish updates to the world in a well-understood format. The idea—which seems strange to type out—is that millions of people in the world could create and publish ideas, thoughts, and content…and then people who enjoyed that content would collect sources into a reader, which was called, well, an RSS Reader. [...] But perhaps most devastating was the web’s move to an advertising model, which RSS runs directly counter to. With RSS you get the content itself, which your reader can choose to display in different ways. Advertisers hate that. They want you to see the original website so they can show you ads the way they want you to see them. I’m sure social media sites had an effect too, because—like aggregators—they were singular watering holes that guaranteed something exciting when you showed up. The common denominator is the move from more effort to less. It’s like in WALL-E, where we turn into morbidly obese people on hoverchairs being shuttled between stimuli. Regardless of the percentages, all those factors combined to destroy the model of getting raw content directly from the source. Well, it’s time to bring that back. It’s time to return to RSS. Google Reader is still dead, but if I remove my nostalgia glasses, feedly is probably better now than Reader ever was. It’s what I’ve been using for years now.

• Building a successful open source community: How coordination and facilitation helps projects scale and mature

  We tend to think of the primary goals of the Linux Foundation’s projects as producing open software, open hardware, open standards, or open data artifacts — the domain of participating programmers & engineers, system architects, and other technical contributors. However, successful projects engaging a broader ecosystem of commercial organizations, particularly when raising funds, benefit from active leadership besides pure technical contributions. Contributors often have work outside the project that often puts demands on their time. It takes real time to build and coordinate a commercial ecosystem, ensure stakeholders are engaged, recruiting and onboarding members, create a neutral governance culture (often amid competitors competing), and to keep various aspects of the ecosystem aligned such as when end users begin to participate. Many Linux Foundation projects fundraise to provide resources for their community. This is an excellent benefit for the technical community when the business ecosystem comes together to invest and help the community obtain resources to build a thriving community and ecosystem. A typical fundraising model in our community is to offer an annual membership structure that provides a yearly fund for the project.

• Oracle’s open-source alter ego behind some of its most popular products

  Open-source innovation may not be the words evoked by a legacy technology company such as Oracle, a company turning 43 years old next month. But the fact is that — like many companies — Oracle’s paid products and services are actually loaded with ingredients from open-source communities, including Linux, to which it is also a contributor. This circular ecosystem of contributing and borrowing back enables some of the versatility and cross-environment compatibility in the company’s latest database and hybrid-cloud offerings.

• Christian Schaller: Into the world of Robo vacums and Robo mops

  So to conclude, would I recommend robot vacuums and robot mops to other parents with you kids? I would say yes, it has definitely helped us keep the house cleaner and nicer and let us spend less time cleaning the house. But it is not a miracle cure in any way or form, it still takes time and effort to prepare and set up the house and sometimes you still need to do especially the mopping yourself to get things really clean. As for the question of iRobot versus other brands I have no input as I haven’t really tested any other brands. iRobot is a local company so their vacuums are available in a lot of stores around me and I drive by their HQ on a regular basis, so that is the more or less random reason I ended up with their products as opposed to competing ones.
