​Beyond Kubernetes: Istio network service mesh

Filed under

First, Docker transformed how we ran applications. Then, Kubernetes changed how we managed containers. Now, the open-source project Istio is building on both to add a network service mesh.

Istio is built on the open-source Envoy proxy. This service mesh enables microservices sharing distributed applications to communicate and work with one another. As Matt Klein, Envoy's creator wrote, Istio provides modern microservice and cloud-native applications with a "unified control plane that ties the pieces together in a coherent way."

Istio also enables DevOps. In a soon-to-be-released blog, Google Cloud's Eric Brewer, VP Infrastructure, and Eyal Manor, VP of Engineering, point out that Istio provides vital DevOps framework "such as a common system for monitoring, logging, authorization, and billing."

What the open source community means to me

Filed under

Every time I tell my friends about my hobby—which became my career as the executive director at The Document Foundation—I face lots of questions. A worldwide community? Contributors around the globe? An open source community? Can you eat that?!

Well, actually sometimes you can eat it. But seriously, today, I'd like to share my very personal view about what the open source community means to me and why being active is not only fun but also benefits your whole life.

IPFire Hardened Linux Firewall Gets 802.11ac Wi-Fi Support, Security Updates

Filed under

Packed with lots of bug fixes and cleanups, the IPFire 2.21 Core Update 125 patch is here to introduce support for the 802.11ac Wi-Fi standard in the IPFire Access Point add-on, which should allow for better wireless coverage and higher network throughputs, especially in home environments. Of course, the machine running IPFire should have a network interface supporting the 802.11ac wireless protocol for this to work.

"Although IPFire might not be the first choice as a wireless access point in larger environments, it is perfect to run a single office or apartment," said Michael Tremer. "Additionally, a new switch allows disabling the so-called neighborhood scan where the access point will search for other wireless networks in the area. If those are found, 40 MHz channel bandwidth is disabled leading to slower throughput."

Google Open-Sources Speaker Diarization AI Technology, Claims 92% Accuracy

Filed under

Google has developed a research paper called Fully Supervised Speaker Diarization where they introduced a new model that uses supervised speaker labels in a more effective manner over traditional approaches. Within this model, an estimation takes place which identifies the number of speakers that participate in a conversation, which increases the amount of labeled data.

As part of NIST SRE 2000 CALLHOME benchmarking, Google’s techniques achieved a diarization error rate (DER) as low as 7.6% where DER is defined as a “percentage of the input signal that is wrongly labeled by the diarization output.” The recent results are improvements over the 8.8% DER achieved using a clustering-based method or the 9.9% DER achieved using deep neural network embedding methods.

  • OECD: open-source software pivotal in artificial intelligence


    Open-source software plays an important role in artificial intelligence (AI). This includes specific software libraries, editors and development environments, and machine learning platforms. So say the authors of the latest OECD Science, Technology and Innovation (STI) Outlook (2018), who identified AI and (big) data as the most prominent disruptive developments in innovation.

  • No More Tab Clutter On Chrome, Engineer From Google Confirms Work On Scrollable Tabstrips

    Google Chrome is undoubtedly one of the more used and popular browsers to the common man. One huge problem that Chrome suffers from is tab cluttering. Tab cluttering happens when a user opens new tabs, one after another, and after a certain number of tabs Chrome automatically reduces the width of all the open tabs in the browser’s UI to make space and accommodate all the new tabs that are being opened.

    This often leads into hiding the webpage header which you would normally see on your tab and then switching between these tabs and looking for your desired tab can become annoying and even mildly infuriating at times.

  • Raptor Blackbird Micro-ATX POWER9 Motherboard Pre-Orders Open Up At $799 USD

    At the start of October, Raptor Computing Systems announced Blackbird as a lower-cost POWER9 motherboard built on a micro-ATX footprint. We now have the firm specs on this motherboard as well as the current pricing as the pre-order window has just opened. 

    Raptor Blackbird is the lowest-cost POWER9 board we've seen to date while being quite promising on the feature front. Earlier this month they probed their customer base about Blackbird potentially coming in at just under $900 USD while today the pre-order period has begun. Raptor is running a Black Friday / Cyber Monday special where this micro-ATX motherboard can be pre-ordered for $799 USD.

  • RcppEigen

    Another minor release of RcppEigen arrived on CRAN today (and just went to Debian too) bringing support for Eigen 3.3.5 to R.

    As we now carry our small set of patches to Eigen as diff in our repo, it was fairly straightforward to bring these few changes to the new upstream version. I added one trivial fix of changing a return value to void as this is also already in the upstream repo. Other than that, we were fortunate to get two nice and focussed PRs since the last release. Ralf allowed us to use larger index values by using R_xlen_t, and Michael corrected use of RcppArmadillo in a benchmarking example script.

Askbot – Create Your Own Q&A Forum Like Stack Overflow

Filed under

Askbot is an open source, simple yet powerful, fast and highly-customizable software for creating a question and answer (Q&A) forum. It is inspired by StackOverflow and YahooAnswers, and written in Python on top of the Django web framework.

It allows for efficient question and answer knowledge management, thus organizations such as Fedora’s Q&A forums and LibreOffice’s Q&A Forums are making good use of it. Askbot can work as a standalone application or can be integrated with your existing Django apps or other web platforms.

  • Picam360-SurfaceWalker: The Open Source Aquatic Drone

    Features called OpenCoralMap and OpenCyanoMap are currently being developed, which automatically upload underwater images filmed during autonomous navigation and data collected with the drone's measuring devices to a server, and display the collected data on a map. 

  • SD Times Open-Source Project of the Week: Acumos AI

    Last week, the LF Deep Learning Foundation announced the first release of its Acumos AI Project. Acumos AI is an open-source framework for building, sharing, and deploying AI applications. It provides a standardized stack and components so that data scientists can “focus on the core competencies and accelerate innovation.”

    Dubbed Athena, this release offers one-click deployment via Docker or Kubernetes, the ability to deploy models into public or private cloud infrastructures, a design studio, security tokens to allow simple onboarding of models into an Acumos AI repository, and an advanced user portal.

  • Kubernetes in production vs. Kubernetes in development: 4 myths

    We recently cleared up some of the common misunderstandings people have about Kubernetes as they start experimenting with it. One of the biggest misunderstandings, though, deserves its own story: Running Kubernetes in production is pretty much the same as running Kubernetes in a dev or test environment.

    Hint: It’s not.

    “When it comes to Kubernetes, and containers and microservices in general, there’s a big gap between what it takes to run in the ‘lab’ and what it takes to run in full production,” says Ranga Rajagopalan, cofounder and CTO of Avi Networks. “It’s the difference between simply running, and running securely and reliably.”

    There’s an important starting point in Rajagopalan’s comment: This isn’t just a Kubernetes issue, per se, but rather more widely applicable to containers and microservices. It is relatively “easy” to deploy a container; operating and scaling containers (and containerized microservices) in production is what introduces complexity.

  • Community is key to open source success and possibly profit

    Open source companies like Redis Labs and MongoDB may be looking to cordon off code to ensure commercial success, but the correct path to open source project success is openness. Thus spake Kubernetes co-founder Brendan Burns, and thus it is. As he noted in a recent interview, "...especially in the infrastructure space, the [open source projects] that make room for other people to be successful are the ones that ultimately win."

How I uncovered my inner geek

Filed under
Red Hat

I'm beginning to feel old. A few months ago, somebody called me a "gray beard" in a comment in an IRC channel. You might have thought my lack of actual beard and the fact that they used the US spelling, rather than the correct "grey," would have meant that I was unaffected, but no, I was. I've been around for a long time, and I've played with more protocols than are probably good for me, so when I briefly told how I'd started out, and a friend replied, "that story is so good," I realised that maybe my experience differs enough from that of many who've joined the profession more recently than me1 that it might be of interest.

So, here goes. I should preface this account by saying that I was quite a geek at school—and by school, I mean "school," not "university"2—doing basic stick-figure animation, writing Mandelbrot set generators, learning PASCAL and Assembly language, trying to hack the very basic school network, that sort of thing. By the time I went to university in 1990, I'd decided to do something a bit different,5 so I spent two years studying English literature (mainly pre-1840) and another two years studying theology (mainly pre-1640). But I kept up some geekery and had a laptop or PC throughout my time at university. Well, I say laptop, but my first PC-compatible was an 8088 Hitachi luggable with an orange screen. Now, that was a computer.

And I had email. This may not seem like a surprise, but as a humanities6 student in a UK university in the early '90s, it took some doing. In order to get access to email at all, you needed a signed form (it was on yellow paper, I think) from your director of studies and your college computing officer to say you had need of it—and even then you were allowed to send emails only to other people on the UK academic network. And my email address used the standard UK academic addressing scheme: Yes, I know this looks backwards. You youngsters: I don't know.

  • buzzes open source projects with free CI service

    Some mark Thanksgiving by helping out at a shelter or pardoning a Turkey, but Drone.IO and Packet have decided to donate a free Continuous Integration service to open source projects.

    Packet is providing “a substantial multi-year donation to support Drone Cloud and therefore help any open source project with a GitHub repository,” Drone founder Brad Rydzewski explained in a blog post.

    The Drone Cloud will support Continuous Delivery Pipelines on bare metal x86 and 32-bit and 64-bit ARM servers, Rydzewski explained.

  • Pioneers in Open Source--Eren Niazi, Part II: the Untold Story

    It was 2014, and everything seemed fine with Eren Niazi and the company he founded, Open Source Storage or OSS, although at the time, both the industry and the market were changing. Not only were open-source technologies used in every form and fashion to enable what has become the cloud, its users also were connecting in droves to take advantages of the many services it offered. We matured into an always connected society.

    As markets evolved and consumer needs evolved, OSS needed to do something to continue to be relevant. Eren and his team came up with a solution to enable more involvement within the Open Source community by building a never-done-before social platform that closed the gap between file sharing and social networking. It also added a gamification component to help encourage participation on top of quality.

Games: Desert Child, KKnD, Twice Circled

  • Desert Child Now Available on Linux, PC, and Mac OS
    Akupara Games is here with an all-new game that blends a mix of hoverbikes with shooting and racing alongside high-resolution pixel art. It's odd to see a game try so many different genres, but Desert Child does that and more. Adventure games are also covered, as you have to go from place to place and explore the world. Your overall goal is to leave Earth before it blows up, and winning the Grand Prix allows you to go to Mars and escape the planet.
  • The KKnD remake using the OpenRA engine has a first release out
    KKnD, the classic strategy game is being revived and the new open source project has the first release out. I was going to write this up last night, but it seems I jumped the gun a bit before they had all the bits in place. Nice to see such quick and polite communication from their team though. Unlike Red Alert and the other titles served by OpenRA, KKnD and KKnD 2 were not made freeware. You will still need the games for the full experience. However, this remake will download the demo files for you to get you going.
  • The lovely aquarium building game Megaquarium just had a big update

Debian Installer Buster Alpha 4 release

The Debian Installer team[1] is pleased to announce the fourth alpha release of the installer for Debian 10 "Buster". Foreword ======== I'd like to start by thanking Christian Perrier, who spent many years working on Debian Installer, especially on internationalization (i18n) and localization (l10n) topics. One might remember graphs and blog posts on Planet Debian with statistics; keeping track of those numbers could look like a pure mathematical topic, but having uptodate translations is a key part of having a Debian Installer that is accessible for most users. Thank you so much, Christian! Read more Also: Debian Installer Buster Alpha 4 Released
