How Kubernetes' Founder is Building an Un-Distribution at Heptio

Filed under
Server
Interviews
OSS

Unlike other software vendors that are part of the Kubernetes community, Heptio doesn't want to build a software distribution of Kubernetes. Rather, the Heptio Kubernetes Service (HKS) is about support and services to help organizations deploy and manage upstream Kubernetes. It's an approach that Heptio has referred to as being an Un-Distribution.

"Our goal with the whole idea of the un-distribution is we want to provide the best parts of a distribution without necessarily some of the downsides that come along with that," Beda said.

Beda said that generally what happens with a distribution of an open source project is that a software vendor takes the upstream code, cleans it up so it's fit for enterprise consumption and then shipping a combination of tools that are prove to work well together.

"Upstream Kubernetes doesn't need a lot of clean up, because the community is so strong and we want to keep it that way," he said.

As such, a lot of the work that Heptio is involved with is all upstream with effort to make Kubernetes easier to install and use. Beda said that Heptio is putting a lot of effort into the kubeadm installer effort from the upstream project as well as the cluster API effort. As part of HKS, Beda said that Heptio is developing a set of validated designs, which integrate best practices for deployment.

Linux
Interviews
OSS

Linus Torvalds is no longer worried about what happens to Linux if he gets hit by a bus, as he's confident there is a work flow process in place that guarantees the success of Linux. Torvalds, the creator of Linux, shared his views on the future of Linux in a conversation with Dirk Hohndel, Chief Open Source Officer at VMware at the Open Source Summit here Aug. 31

Torvalds exchanged lively banter with Hohndel on a wide variety of topics ranging from the recent Meltdown and Spectre vulnerabilities, the state of hardware performance, the Linux development process and the future of Linux without Torvalds' guiding hand.

"What I really worry about is the flow of patches and the workflow is more important than the code," Torvalds said. "If you have the right work flow, code will sort itself out and if a bug happens, we know how to deal with it."

Interviews

Lennart Jern is a Swedish-speaking Finn, who has been living in Umeå, Sweden, for about three years. He was born and raised in southern Finland where he obtained his master’s degree in applied mathematics. His time at university exposed Lennart’s true passion. “While at the university, I realized that computer science was really what I wanted to work with.” In order to follow his dream of working in computer science he moved to Sweden with his wife to pursue a master’s program in computer science. After a short while he had learned enough to land a job with a local startup. “I’m working with cloud/distributed systems, specifically with tools like kubernetes and OpenShift.”

Lennart’s first contact with Linux was in 2006. Some of the computers in his high school were running OpenSuse. He installed Ubuntu’s Hardy Heron in 2008 and has been using Linux ever since.

  • [Podcast] PodCTL #44 – Looking at 3yrs of Kubernetes

    With Kubernetes recently celebrating it’s 3rd anniversary, we thought it would be a good idea to look back at what has made the project successful, the growth of the ecosystem, the adoption by companies around the world, as well as areas where the market feels that there is still room for improvement.

  • Ars on your lunch break: Tim O’Reilly on why the future doesn’t have to suck

    In today’s installment, Tim rejects the fashionable forecast that automation will eradicate all human jobs next week. Being closer than most of us to Jeff Bezos, he knows a thing or three about operations at Amazon, which presents a fascinating case in point.

    The company began a hugely successful two-year robot buying spree in 2014. The robots automated countless repetitive and dangerous human tasks. And during that time, the company hired more than 100,000 new people in its warehouses. It turns out, these robots amplify the productivity of the folks who work with them. And when bosses get more bang for their buck from a category of worker, they tend to hire more of them.

Review: The Linux Podcast Scene – all the movers and shakers

Filed under
Interviews

Podcasts are shows, similar to radio or TV shows, that are produced by professionals or amateurs and made available on the internet to stream and/or download. They have entered into a more mature phase.

Linux blogs and web sites carry a huge library of information to tap into about the Linux scene. Podcasts have some advantages (and disadvantages) over these resources. Portability is a key advantage of podcasts. You can be driving across states, or walking down the street, and keep up to date with the latest Linux scene.

It’s been a long time since we covered Linux podcasts. Sadly, some great shows have podfaded, but there’s new ones entering the scene. We’ve therefore compiled a fairly comprehensive roundup of active Linux-related podcasts. We don’t feature in this article podcasts that have stopped releasing new shows.

Ars on your lunch break: Tim O‘Reilly discusses the birth of “open source”

OSS

Below, you’ll find the second installment of the After On interview with legendary tech publisher and prognosticator Tim O’Reilly. Please check out part one if you missed it. Otherwise, press play on the embedded player, or pull up the transcript—both of which are below.

O’Reilly and I start off today talking about The Whole Internet User’s Guide & Catalog, which he published in 1992. And yup—that’s a two at the end of that number. As in, a full year before the first release of the Mosaic browser. Of course, there was a World Wide Web before Mosaic—and all 200 of its sites are listed in this book (along with various non-WWW Internet stuff that was around back then).

Jumping forward many years, O’Reilly tells us about convening a small summit of tech honchos, which quite literally named open source software. The nameless-ish phenomenon was already a big deal by then and was destined to become a huge one. But names do matter (and their lack even more so). The summit’s real purpose was to stridently promote this new approach to code to the both industry and the press in hopes of terminating the suffocating reign of Microsoft and others.

  • Awards roll call: Red Hat awards, June to October 2018
    Depending on the weather in your region, it’s safe to say that the seasons are changing so it’s a good time to look back at what was a busy few months for Red Hat, especially when it came to industry awards for our technical and product leadership. In recent months, Red Hat products and technologies took home twenty awards, highlighting the breadth and depth of our product portfolio as well as the expertise that we provide to our customers. In addition, Red Hat as a company won five awards recognizing its growth and culture as a leader in the industry.
  • More advice from a judge - what it takes to win a Red Hat Innovation Award
    Last year I penned the below post to provide insight into what the judges of the Red Hat Innovation Awards are looking for when reviewing submissions. Looking back, I would give almost the identical advice again this year...maybe with a few tweaks. With all the stellar nominations that we receive, the question I often get is, “how can we make our entry standout?” There’s no magic formula for winning the Red Hat Innovation Awards, but there are things that the other judges and I look for in the entries. Overall, we’re looking for the project that tells a compelling story. It’s not just about sharing what Red Hat products and services you used, we want to hear the full narrative. What challenges did you face; how you implemented the project; and ultimately, what was the true business impact and transformation that took place? Submissions that are able to showcase how open source culture and values were key to success, or how the project is making a difference in the lives of others, are the entries that most often rise to the top.

  • Blockcerts Updates Open Source Blockchain Architecture
    Learning Machine is making changes to its Blockcerts Credential Issuer, Verifier and Wallet to enable native support for records issuance and verification using any blockchain. Blockcerts was launched by Learning Machine and MIT Media Lab in 2016 as new way to allow students to receive digital diplomas through an app, complementing a traditional paper degree. Blockcerts was originally designed to be blockchain-agnostic, which means that open standards can be used to anchor records in any blockchain. The Blockcerts Universal Identifier recognizes which blockchain is being used and verifies accordingly. Currently, the open source project has added support for bitcoin and Ethereum blockchains, but anyone can add support through the project's GitHub page.

  • On the low adoption of automated testing in FOSS
    A few times in the recent past I've been in the unfortunate position of using a prominent Free and Open Source Software (FOSS) program or library, and running into issues of such fundamental nature that made me wonder how those issues even made it into a release. In all cases, the answer came quickly when I realized that, invariably, the project involved either didn't have a test suite, or, if it did have one, it was not adequately comprehensive. I am using the term comprehensive in a very practical, non extreme way. I understand that it's often not feasible to test every possible scenario and interaction, but, at the very least, a decent test suite should ensure that under typical circumstances the code delivers all the functionality it promises to. [...] Most FOSS projects, at least those not supported by some commercial entity, don't come with any warranty; it's even stated in the various licenses! The lack of any formal obligations makes it relatively inexpensive, both in terms of time and money, to have the occasional bug in the codebase. This means that there are fewer incentives for the developer to spend extra resources to try to safeguard against bugs. When bugs come up, the developers can decide at their own leisure if and when to fix them and when to release the fixed version. Easy! At first sight, this may seem like a reasonably pragmatic attitude to have. After all, if fixing bugs is so cheap, is it worth spending extra resources trying to prevent them?

  • Teaching With an Index Card: the Benefits of Free, Open-Source Tools
  • Decentralized Authentication for Self-Sovereign Identities using Name Systems
    The GNU Name System (GNS) is a fully decentralized public key infrastructure and name system with private information retrieval semantics. It serves a holistic approach to interact seamlessly with IoT ecosystems and enables people and their smart objects to prove their identity, membership and privileges - compatible with existing technologies. In this report we demonstrate how a wide range of private authentication and identity management scenarios are addressed by GNS in a cost-efficient, usable and secure manner. This simple, secure and privacy-friendly authentication method is a significant breakthrough when cyber peace, privacy and liability are the priorities for the benefit of a wide range of the population. After an introduction to GNS itself, we show how GNS can be used to authenticate servers, replacing the Domain Name System (DNS) and X.509 certificate authorities (CAs) with a more privacy-friendly but equally usable protocol which is trustworthy, human-centric and includes group authentication. We also built a demonstrator to highlight how GNS can be used in medical computing to simplify privacy-sensitive data processing in the Swiss health-care system. Combining GNS with attribute-based encryption, we created ReclaimID, a robust and reliable OpenID Connect-compatible authorization system. It includes simple, secure and privacy-friendly single sign-on to seamlessly share selected attributes with Web services, cloud ecosystems. Further, we demonstrate how ReclaimID can be used to solve the problem of addressing, authentication and data sharing for IoT devices. These applications are just the beginning for GNS; the versatility and extensibility of the protocol will lend itself to an even broader range of use-cases. GNS is an open standard with a complete free software reference implementation created by the GNU project. It can therefore be easily audited, adapted, enhanced, tailored, developed and/or integrated, as anyone is allowed to use the core protocols and implementations free of charge, and to adopt them to their needs under the terms of the GNU Affero General Public License, a free software license approved by the Free Software Foundation.

  • RApiDatetime 0.0.4: Updates and Extensions
    The first update in a little while brings us release 0.0.4 of RApiDatetime which got onto CRAN this morning via the lovely automated sequence of submission, pretest-recheck and pretest-publish. RApiDatetime provides seven entry points for C-level functions of the R API for Date and Datetime calculations. The functions asPOSIXlt and asPOSIXct convert between long and compact datetime representation, formatPOSIXlt and Rstrptime convert to and from character strings, and POSIXlt2D and D2POSIXlt convert between Date and POSIXlt datetime. This releases brings asDatePOSIXct as a seventh courtesy of Josh Ulrich. All these functions are all fairly useful, but not one of them was previously exported by R for C-level use by other packages. Which is silly as this is generally extremely carefully written and tested code.
