Quick Roundup

OSS: Blockchain, DeepBrain, Redox OS, OpenBuilds, Red Hat Summit and FOSSASIA

  • It's About Time DApps Unlocked the Mass-Market Momentum for Blockchain
    There’s more to Blockchain technology than Bitcoin and other cryptocurrencies. At its fundamental level, Blockchain technology engenders trusts in inherently trustless environments. Protocol blockchains such as Bitcoin, Ethereum, EOS, GoChain, Steem and xDai have provided a launchpad for developers to work on DApps. DApps are typically open source applications not owned by anyone, immune from downtimes; and that cannot be shut down by a government or its agencies. The rapid proliferation of Decentralized Applications (DApps) powered a bull run in cryptocurrencies in 2017. Right now, there are more than 2000 DApps designed to solve specific market problems across industries such as health, data storage, finance, gaming, and governance.
  • DeepBrain Chain outlines release of DBC 0.3.6.0 beta in progress report
    DeepBrain Chain detailed the release of DBC 0.3.6.0 beta of its AI Training Net, which allows users to rent computing power to train artificial intelligence algorithms. DeepBrain Chain claimed numerous feature inclusions and and improvements, many pertaining to the scheduling and activation of tasks. In DBC 0.3.6.0, if an AI training task has been stopped a specified period of time, its storage will be deleted automatically. However, the task can be restarted at any time before deletion. If a node has been restarted, reactivation of any previous training tasks will require manual user authorization. [...] A decision was made recently by the community concerning the open source licensing of DeepBrain Chain’s code. Over 55 percent of the members polled voted to not make the code fully open source by the end of March.
  • Redox OS 0.5.0
    It has been one year and four days since the last release of Redox OS! In this time, we have been hard at work improving the Redox ecosystem. Much of this work was related to relibc, a new C library written in Rust and maintained by the Redox OS project, and adding new packages to the cookbook. We are proud to report that we have now far exceeded the capabilities of newlib, which we were using as our system C library before. We have added many important libraries and programs, which you can see listed below.
  • Redox OS 0.5 Released With New C Library Written In Rust
    It's been just over one year since the previous release of Redox OS while today this Rust-written operating system has finally been succeeded by Redox OS 0.5.  It's taken a while since the previous release of Redox OS as they have been focusing their attention on Relibc, a C library implementation written within the Rust programming language. Relibc is now used as the operating system's default C library.
  • Get Moving with New Software from OpenBuilds
    If you’re reading Hackaday, you’ve probably heard of OpenBuilds. Even if the name doesn’t sound familiar, you’ve absolutely seen something on these pages that was built with their components. Not only is OpenBuilds a fantastic place to get steppers, linear rails, lead screws, pulleys, wheels, and whatever else you need to make your project go, they’re also home to an active forum of people who are passionate about developing open source machines. As if that wasn’t enough reason to head over to the OpenBuilds website, [Peter Van Der Walt] recently wrote in to tell us about some new free and open source software he and the team have been working on that’s designed to make it easier than ever to get your creations cutting, lasing, milling, and whatever else you could possibly imagine. If you’ve got a machine that moves, they’ve got some tools you’ll probably want to check out.
  • Dive into developer-focused sessions at Red Hat Summit
    Red Hat Summit is just around the corner, and it’s shaping up to be best Red Hat developer event ever. This year, attendees will get to choose from more than 300 sessions, not to mention booth presentations, parties, labs, and training. To help you cut through the clutter, we’ve created a list of developer specific activities and sessions that will help you shape your Red Hat Summit experience. Most of these sessions are part of the Cloud-Native App Dev track, with a few other sessions that we think will appeal to you as a developer. For more information on these sessions, visit the Red Hat Summit session listing page and sort by “cloud-native app dev” track.
  • 10th year of FOSSASIA
    This FOSSASIA was special as it marked its 10th year! It was quite impressive to witness a FOSS conference to continue growing this long with growing community. The four day conference schedule was packed with various interesting talks, workshops, hackathon and other engaging activities.

Reducing sysadmin toil with Kubernetes controllers

Kubernetes is a platform for reducing toil cunningly disguised as a platform for running containers. The element that allows for both running containers and reducing toil is the Kubernetes concept of a Controller. [...] The canonical example of this in action is in how we manage Pods in Kubernetes. A Pod is effectively a running copy of an application that a specific worker node is asked to run. If that application crashes, the kubelet running on that node will start it again. However, if that node crashes, the Pod is not recovered, as the control loop (via the kubelet process) responsible for the resource no longer exists. To make applications more resilient, Kubernetes has the ReplicaSet controller. The ReplicaSet controller is bundled inside the Kubernetes controller-manager, which runs on the Kubernetes master node and contains the controllers for these more advanced resources. The ReplicaSet controller is responsible for ensuring that a set number of copies of your application is always running. To do this, the ReplicaSet controller requests that a given number of Pods is created. It then routinely checks that the correct number of Pods is still running and will request more Pods or destroy existing Pods to do so. By requesting a ReplicaSet from Kubernetes, you get a self-healing deployment of your application. You can further add lifecycle management to your workload by requesting a Deployment, which is a controller that manages ReplicaSets and provides rolling upgrades by managing multiple versions of your application's ReplicaSets.

Server: IBM, LAMP and Kubernetes

  • A HATS For Many Occasions
    IBM gives customers plenty of options when it comes to its Rational Host Access Transformation software, including several modes of operation, different runtime options, and support for different operating systems in screen modernization engagements. With last week’s launch of HATS version 9.7, the development and deployment options got even wider. Regardless of which downstream options a HATS customer ultimately chooses, it all starts out basically the same on the front side of the sausage machine: Customers come to HATS because they have a 5250 (or 3270 or VT100) application that they want to transform, but they don’t want to go through the hassle, expense, and risk of modifying the IBM i, z/OS, or Unix application’s source code.
  • Six top skills that you should acquire in 2019
    There is a growing demand for the fullstack development skill set, which is the ability to develop tech both on the front-end/client side and back-end/server side. As you can’t learn all, select combinations like MEAN or LAMP stack.
  • Kubernetes and the Enterprise
    The reason we were having this conversation was around SUSE’s Cloud Application Platform (CAP). This is our Kubernetes focused Cloud Foundry distribution. And as part of the Kubernetes focus, we have been supporting and running SUSE CAP on Azure’s AKS for the last year or so. The conversation continued with observations that Kubernetes was clearly the future across IT. Yet to date, Cloud Foundry still has a good following with the large enterprise. And the thinking was that the Cloud Foundry approach really helped the large enteprise work with their applications, even if the applications were purely ‘container’ applications. Cloud Foundry makes the container-side of managing your ‘container’ application transparent. This approach ultimately lowers the tasks, breadth of tooling, and knowledge you have to surround Kubernetes with. It was with this thought, that a light-bulb went on.

(OSS) Web Project Management Software and OSI

  • 10 Excellent Web Project Management Software

    Project management is the application of processes, methods, knowledge, skills and experience to achieve the project objectives. Project management tools encompass many different types of software such as scheduling, resource allocation, collaboration software, quality management, and cost control / budget management. This type of software is typically used by project managers looking to plan and control resources, costs and schedules to meet the objectives of a project.

    It can be very satisfying planning and delivering projects on time. One of the methods that has always helped me is PRINCE2, a de facto process-based method for effective project management. But project management software is equally as important to the success of a project.

    There are a number of different types of project management tools. One of the industry standards is the Gantt Chart, which provides a graphical displays of all the tasks that a project is composed of. Each bar on the chart is a graphical representation of the length of time the task is planned to take. Other popular tools include PERT charts (a method for analyzing the tasks involved in completing a project), Product Breakdown Structure (a hierarchical tree structure of components that make up a project deliverable), and Work Breakdown Structure (a hierarchical tree structure of deliverables and tasks that need to be performed to complete a project).

    To provide an insight into the quality of software that is available, we have compiled a list of 10 excellent web based project management software. Hopefully, there will be something of interest for anyone who wishes to organise their projects. Here’s our rating chart.

  • New Open Source Initiative Sponsors Emphasize Diverse/Broad Industry Adoption [Ed: In fact, so diverse that even companies that attack Open Source are in the Board and are sponsors, e.g. Microsoft]

    Today the Open Source Initiative® (OSI), the global non-profit formed to educate about and advocate for the benefits of open source software and communities, is pleased to announce the corporate sponsorship of Daily Fantasy Cafe and Lineups.com. The contributions from these diverse companies underscore the broad appeal and applicability of open source software across industries.

    Over 20 years of work, the OSI has constantly found adoption of, and contributions to, open source software growing, year over year, as companies realize the benefits and value of collaborative communities of practice. No longer limited to the data centers and development shops of tech-companies, open source software is now pervasive across diverse industries, all seeking to reduce costs, drive innovation, decrease time to market, increase quality, and avoid vendor lock-in.

    “The OSI is actively engaged with organizations across government, education, manufacturing, agriculture, entertainment—everywhere.  As new industries emerge, like fantasy sports, they’re choosing to be, ‘open source first,’” says Patrick Masson, General Manager of the Open Source Initiative. “Daily Fantasy Cafe and Lineups really show how broad the appeal is now, and most inspiring, how companies that benefit from open source choose to contribute back. Open source is a collaborative effort, projects need code, community, and cash.”

  • More AMD FreeSync Patches Likely Coming To Linux 5.2

    While the Linux 5.0 kernel brought initial support for the long-awaited open-source FreeSync implementation, the Linux 5.2 kernel coming out this summer will likely have additional improvements. 

    Open-source developer Mario Kleiner has been working on a set of patches this month for enabling proper vblank and page-flip time-stamping when in the FreeSync/VRR (Variable Rate Refresh) mode. This work makes the vblank timestamps as accurate as in the fixed refresh rate behavior. 

  • Primus-VK: PRIME-Style GPU Offloading For Vulkan

    For those with a PRIME style notebook or just making use of dual/multiple graphics processors in your system, Primus-VK allows for using a secondary/dedicated GPU for rendering while driving the display from the alternative (often integrated graphics) GPU. Primus-VK is implemented as a Vulkan layer as a clean approach for dealing with multiple GPUs in a Vulkan world. 

    Primus-VK pursues Vulkan GPU offloading by implementing this logic as a Vulkan layer for handling the rendering on one GPU and then when it comes to display-time it copies the image over to the integrated/primary GPU. This layer can be installed per-user or system-wide and has been tested on the likes of Debian. ENABLE_OPTIMUS_LAYER=1 is the environment variable used for activating the behavior. Primus-VK has also been tested with Windows games under Wine.

  • NVIDIA Releases Nsight Graphics 2019.2 With Vulkan Profiling Support

    Released for GDC/GTC week was Nsight Graphics 2019.2, the proprietary cross-platform, closed-source utility tool for debugging, profiling, and analyzing Direct3D, OpenGL, and other GPU-accelerated APIs. 

    With this week's Nsight Graphics 2019.2 release they finally have added Vulkan profiling support. This support allows inspecting GPU performance metrics under Vulkan workloads within the program's Range Profiler. Other new additions include improvements for running Steam games on Linux, a feedback button, and enhancements to the accelerated structure viewer and API inspector.

  • Security updates for Friday
  • Linux apps on Chrome OS will soon support Android-based VPN connections

    Google is finally fixing Chrome OS's inability to protect Linux apps with a VPN, like the ones downloadable from the Play Store.

  • BleachBit 2.2

    Designed for Linux and Windows systems, it wipes clean thousands of applications including Firefox, Internet Explorer, Adobe Flash, Google Chrome, Opera, Safari, and more. Beyond simply deleting files, BleachBit includes advanced features such as shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster. Better than free, BleachBit is open source.

  • Stand by for urgent security update

    Pwn2Own came and went and Firefox fell with it. The __proto__ vulnerability seems exploitable in TenFourFox, though it would require a PowerPC-specific attack to be fully weaponized, and I'm currently evaluating the other bug. Builds ("FPR13 SPR1") including fixes for either or both depending on my conclusions will be issued within the next couple days.

  • Steam vulnerability exposed users to account hijacking and malware [Ed: proprietary software cannot hide its holes for very long (or until it's too late to hide)]

    OpenArena, one of the most well known open-source games built atop the ioquake3 engine of what started out as id Tech 3, has now seen an independent port to the Vulkan graphics API.

    The vkOpenArena game now marks the latest vintage game seeing a port to Vulkan. Independent developer Sui Jingfeng has been working on vkOpenArena as a port of the OpenArena engine over to using the Vulkan graphics API rather than Vulkan.

Servers: Kubernetes, Docker, and Software Defined Infrastructure

Filed under
Server
  • Kubernetes End-to-end Testing for Everyone

    More and more components that used to be part of Kubernetes are now being developed outside of Kubernetes. For example, storage drivers used to be compiled into Kubernetes binaries, then were moved into stand-alone Flexvolume binaries on the host, and now are delivered as Container Storage Interface (CSI) drivers that get deployed in pods inside the Kubernetes cluster itself.

    This poses a challenge for developers who work on such components: how can end-to-end (E2E) testing on a Kubernetes cluster be done for such external components? The E2E framework that is used for testing Kubernetes itself has all the necessary functionality. However, trying to use it outside of Kubernetes was difficult and only possible by carefully selecting the right versions of a large number of dependencies. E2E testing has become a lot simpler in Kubernetes 1.13.

  • Why Docker Containers Matter, 6 Years After the Project First Started

    Docker, the eponymous name of the container technology and the company behind it, celebrated its six-year anniversary on March 20. From its earliest days, even as just a 1-year-old effort back in 2014, there was no shortage of optimism and excitement about Docker. With the Docker model, applications are more portable and run inside of containers, which are isolated instances that provide a more agile approach for development and deployment. Docker also introduced the "dockerfile" packaging format, which defines how a container image should be built.

    The container model that Docker first introduced has evolved over the past six years and is now the cornerstone of the broader cloud-native space, which includes the open-source Kubernetes container orchestration system. In this eWEEK Data Points article, we look at some of the key facts about Docker and the cloud-native revolution it has inspired.

  • Planning for a Software Defined Infrastructure

    Seems you can’t pick up an IT magazine these days without hearing the term software defined infrastructure. It’s easy to get caught up in the hype. You might be thinking ‘people are talking about so it must be something that we need.” Some of you are wincing from the pain felt in trying to adopt the latest technologies without properly looking at what will work for your environment and business.

    In a software defined world, the computing infrastructure is virtualized. That is, it is delivered as a service. Management and control of the networking, storage and/or data center infrastructure is automated by intelligent software rather than by the hardware components of the infrastructure.

  • Participating at #Scale17x

    Everytime somebody asks me about Scale I can only think of the same: Scale is the most important community lead conference in North America and it only gets better by the years. This year it celebrated its seventeenth edition and it just struck me: with me being there this year, there have been more Scales I have attended than I have not. This is my nineth conference out of 17.

    The first time that I attended it was 2011, it was the edition followed by FudCon Tempe 2010 which happened to be my first Fedora conference and it was also the first time I got to meet some contributors that I had previously collaborated with, many of which I still consider my brothers.

    As for this time, I almost didn’t make it as my visa renewal was resolved on Friday’s noon, one day after the conference started. I recovered it that same day and book a flight in the night. I couldn’t find anything to LAX -as I regularly fly- so I had to fly to Tijuana and from there I borrowed a cart to Pasadena. Long story short: I arrived around 1:30 AM on Saturday.

Python 2 support will formally reach end-of-life on 1 January 2020 and Fedora 31 is preparing for that by working to drop packages (or parts of packages) that depend upon Python 2.

Fedora has been pushing for a Python 2 to Python 3 migration for many cycles now -- as most Linux distributions have -- while with Fedora 31 they are planning a "mass Python 2 package removal" if necessary. They are planning to closely track the state of packages depending upon Python 2 to either drop the packages or allow packagers to easily abandon Python 2 parts of programs.

A preliminary review of /e/

Filed under
OS
Android

I’ve been running LineageOS on my phone for a while now (and cyanogenmod before that) and been reasonably happy overall. Still even LineageOS is pretty intertwined with the google ecosystem and worries me, especially given that google is first and foremost an ad company.
I happened to run accross mention of /e/ somewhere and since LineageOS did a jump from being based on ASOP15 to ASOP16 which required a new install anyhow, I decided to check it out.
As you may have gathered from the above, /e/ is a phone OS and platform, forked off from LineageOS14.1. It’s located at https://e.foundation based in france (a non profit) headed by Gaël Duval, who Linux folks may know from his Mandrake/Mandriva days. The foundation has a lot of noble goals, starting with “/e/’s first mission is to provide everyone knowledge and good practices around personal data and privacy.” They also have a slogan “Your data is your data!”
I downloaded and installed a 0.5 version here. Since I already had my phone unlocked and TWRP recovery setup, I just backed up my existing LineageOS install (to my laptop), wiped the phone and installed /e/. The install was painless and since (of course) there’s no google connections wanted, I didn’t even have to download a gapps bundle. The install worked just fine and I was off and exploring:

  • William Lachance: New ideas, old buildings

    Last week, Brendan Colloran announced Iodide, a new take on scientific collaboration and reporting that I’ve been really happy to contribute to over the past year-and-a-bit. I’ve been describing it to people I meet as kind of "glitch meets jupyter " but that doesn’t quite do it justice. I’d recommend reading Brendan’s blog post (and taking a look at our demonstration site) to get the full picture.

    One question that I’ve heard asked (including on Brendan’s post) is why we chose a rather conventional and old technology (Django) for the server backend. Certainly, Iodide has not been shy about building with relatively new or experimental technologies for other parts (e.g. Python on WebAssembly for the notebooks, React/Redux for the frontend). Why not complete the cycle by using a new-fangled JavaScript web server like, I don’t know, NestJS? And while we’re at it, what’s with iodide’s ridiculous REST API? Don’t you know GraphQL is the only legitimate way to expose your backend to the world in 2019?

From Trusty to Bionic - my Ultrabook story

Filed under
Ubuntu

I am happy with how the upgrade went, given that I've actually bumped the system two major releases. Apart from small issues, there was nothing cardinal in the move. No data loss, no complications, no crashes. All my stuff remains intact, and so does Windows 8, living happily together and sharing the disk with Ubuntu. Mission accomplished.

But we ain't done. I need to make the system as usable as possible. Which means Unity testing - and Plasma testing, of course, duh! Indeed, this remains a productivity box, and as such, it must fulfill some very stringent requirements. It must be stable, fast and elegant. It must work with me every step of the way, and it must allow me to transparently and seamlessly use various programs that I need. On this particular machine, that would be video editing with Kdenlive, that would be image processing with GIMP, the use of encryption and VPN tools, tons of writing on the superbly ergonomic Asus keyboard. But all that and more - coming soon.

For now, thank you Trusty for five sweet, loyal years. May you ReST in ethernet peace.

    Maxim Levitsky of Red Hat sent out a "request for comments" patch series this week introducing NVMe VFIO media storage device support for the Linux kernel.

    Levitsky is pursuing faster virtualization of storage while striving for low latency and that led to the creation of a VFIO-based mediated device driver to pass an NVMe partition or namespace to a guest. This NVMe VFIO mediated device support would allow virtualized guests to run their unmodified/standard NVMe device drivers, including the Windows drivers, while still allowing the NVMe device to be shared between the host and guest.

  • Allan Day: Parental Controls and Metered Data Hackfest

    This week I participated in the Parental Controls and Metered Data Hackfest, which was held at Red Hat’s London office.

    Parental controls and metered data already exist in Endless and/or elementary OS in some shape or form. The goal of the hackfest was to plan how to upstream the features to GNOME. It’s great to see this kind of activity from downstreams so I was very happy to contribute in my capacity as an upstream UX designer.

    There have been a fair few blog posts about the event already, so I’m going to try and avoid repeating what’s already been written…

  • Not posting here means not there is nothing done

    I looking with fears to this strange ideas Mindshare has for the future of the Ambassadors. You can not write reports if you not have an event, so I telling here now how hard it is in this country to organize an event.

    Since October 2018 I search for a place which would host the next Translation Sprint. We have tons of co-working spaces or NGO’s which have space available. But is always the same I asked e.g. Open Institute, answer we can host you just on Saturday. And I had actually to write there several times and even make calls because I got no answer for the first contact. The same on The Desk, we can host you only on Saturday. This makes no sense in Cambodia, it is a regular working day, because they have 28 holidays. So most people have to work until 2pm. What sucked on this one, I was working on it since end of January. So first meeting was setup for 11th March, I went there but nobbody there to meet me. This is normal cambodian working style I dont tell I am busy and cant meet you and give you an alternative time. Well the promised mail with an alternative time never arrived, so I had to ask for it again. Second meeting was then this Monday, I spent an hour with them with the useless result of “just Saturday”. But there is light on the horizon OpenDevelopment might host us but here just on Sunday, which is for us better then just Saturday. So six months, hundreds of mails and several meetings and achieved nothing. How easy is it to setup a Fedora Womans Day in the Pune office, compared to this and then just travel around the world to visit other events and this is then called “active”

    If you like puzzle games and marbles today is your lucky day as I came across Flux Caves, which merges them into one game.

    It's early-on in development but it has a pretty great idea. It's like piecing together an oversized marble-run, with each level having various tubes and other special blocks missing that you need to slot into place.

  • Cities: Skylines is another game having a free weekend on Steam right now

    As a reminder, it recently turned four years old and it's showing no signs of slowing down with multiple thousands on it every day. If you do decide to give it a go, I highly recommend the Clouds & Fog Toggler mod from the Steam Workshop to give you a really clear view.

    That's another thing that I love about Cities: Skylines, there's a huge amount of extra content available for it like maps, mods, scenarios and more. The mod selection is incredibly varied too from simple tools to automatically bulldoze abandoned or burned down buildings to adding in entirely new ways to play.

  • It's About Time DApps Unlocked the Mass-Market Momentum for Blockchain
    There’s more to Blockchain technology than Bitcoin and other cryptocurrencies. At its fundamental level, Blockchain technology engenders trusts in inherently trustless environments. Protocol blockchains such as Bitcoin, Ethereum, EOS, GoChain, Steem and xDai have provided a launchpad for developers to work on DApps. DApps are typically open source applications not owned by anyone, immune from downtimes; and that cannot be shut down by a government or its agencies. The rapid proliferation of Decentralized Applications (DApps) powered a bull run in cryptocurrencies in 2017. Right now, there are more than 2000 DApps designed to solve specific market problems across industries such as health, data storage, finance, gaming, and governance.
  • DeepBrain Chain outlines release of DBC 0.3.6.0 beta in progress report
    DeepBrain Chain detailed the release of DBC 0.3.6.0 beta of its AI Training Net, which allows users to rent computing power to train artificial intelligence algorithms. DeepBrain Chain claimed numerous feature inclusions and and improvements, many pertaining to the scheduling and activation of tasks. In DBC 0.3.6.0, if an AI training task has been stopped a specified period of time, its storage will be deleted automatically. However, the task can be restarted at any time before deletion. If a node has been restarted, reactivation of any previous training tasks will require manual user authorization. [...] A decision was made recently by the community concerning the open source licensing of DeepBrain Chain’s code. Over 55 percent of the members polled voted to not make the code fully open source by the end of March.
  • Redox OS 0.5.0
    It has been one year and four days since the last release of Redox OS! In this time, we have been hard at work improving the Redox ecosystem. Much of this work was related to relibc, a new C library written in Rust and maintained by the Redox OS project, and adding new packages to the cookbook. We are proud to report that we have now far exceeded the capabilities of newlib, which we were using as our system C library before. We have added many important libraries and programs, which you can see listed below.
  • Redox OS 0.5 Released With New C Library Written In Rust
    It's been just over one year since the previous release of Redox OS while today this Rust-written operating system has finally been succeeded by Redox OS 0.5.  It's taken a while since the previous release of Redox OS as they have been focusing their attention on Relibc, a C library implementation written within the Rust programming language. Relibc is now used as the operating system's default C library.
  • Get Moving with New Software from OpenBuilds
    If you’re reading Hackaday, you’ve probably heard of OpenBuilds. Even if the name doesn’t sound familiar, you’ve absolutely seen something on these pages that was built with their components. Not only is OpenBuilds a fantastic place to get steppers, linear rails, lead screws, pulleys, wheels, and whatever else you need to make your project go, they’re also home to an active forum of people who are passionate about developing open source machines. As if that wasn’t enough reason to head over to the OpenBuilds website, [Peter Van Der Walt] recently wrote in to tell us about some new free and open source software he and the team have been working on that’s designed to make it easier than ever to get your creations cutting, lasing, milling, and whatever else you could possibly imagine. If you’ve got a machine that moves, they’ve got some tools you’ll probably want to check out.
  • Dive into developer-focused sessions at Red Hat Summit
    Red Hat Summit is just around the corner, and it’s shaping up to be best Red Hat developer event ever. This year, attendees will get to choose from more than 300 sessions, not to mention booth presentations, parties, labs, and training. To help you cut through the clutter, we’ve created a list of developer specific activities and sessions that will help you shape your Red Hat Summit experience. Most of these sessions are part of the Cloud-Native App Dev track, with a few other sessions that we think will appeal to you as a developer. For more information on these sessions, visit the Red Hat Summit session listing page and sort by “cloud-native app dev” track.
  • 10th year of FOSSASIA
    This FOSSASIA was special as it marked its 10th year! It was quite impressive to witness a FOSS conference to continue growing this long with growing community. The four day conference schedule was packed with various interesting talks, workshops, hackathon and other engaging activities.

Reducing sysadmin toil with Kubernetes controllers

Kubernetes is a platform for reducing toil cunningly disguised as a platform for running containers. The element that allows for both running containers and reducing toil is the Kubernetes concept of a Controller. [...] The canonical example of this in action is in how we manage Pods in Kubernetes. A Pod is effectively a running copy of an application that a specific worker node is asked to run. If that application crashes, the kubelet running on that node will start it again. However, if that node crashes, the Pod is not recovered, as the control loop (via the kubelet process) responsible for the resource no longer exists. To make applications more resilient, Kubernetes has the ReplicaSet controller. The ReplicaSet controller is bundled inside the Kubernetes controller-manager, which runs on the Kubernetes master node and contains the controllers for these more advanced resources. The ReplicaSet controller is responsible for ensuring that a set number of copies of your application is always running. To do this, the ReplicaSet controller requests that a given number of Pods is created. It then routinely checks that the correct number of Pods is still running and will request more Pods or destroy existing Pods to do so. By requesting a ReplicaSet from Kubernetes, you get a self-healing deployment of your application. You can further add lifecycle management to your workload by requesting a Deployment, which is a controller that manages ReplicaSets and provides rolling upgrades by managing multiple versions of your application's ReplicaSets.

Server: IBM, LAMP and Kubernetes

  • A HATS For Many Occasions
    IBM gives customers plenty of options when it comes to its Rational Host Access Transformation software, including several modes of operation, different runtime options, and support for different operating systems in screen modernization engagements. With last week’s launch of HATS version 9.7, the development and deployment options got even wider. Regardless of which downstream options a HATS customer ultimately chooses, it all starts out basically the same on the front side of the sausage machine: Customers come to HATS because they have a 5250 (or 3270 or VT100) application that they want to transform, but they don’t want to go through the hassle, expense, and risk of modifying the IBM i, z/OS, or Unix application’s source code.
  • Six top skills that you should acquire in 2019
    There is a growing demand for the fullstack development skill set, which is the ability to develop tech both on the front-end/client side and back-end/server side. As you can’t learn all, select combinations like MEAN or LAMP stack.
  • Kubernetes and the Enterprise
    The reason we were having this conversation was around SUSE’s Cloud Application Platform (CAP). This is our Kubernetes focused Cloud Foundry distribution. And as part of the Kubernetes focus, we have been supporting and running SUSE CAP on Azure’s AKS for the last year or so. The conversation continued with observations that Kubernetes was clearly the future across IT. Yet to date, Cloud Foundry still has a good following with the large enterprise. And the thinking was that the Cloud Foundry approach really helped the large enteprise work with their applications, even if the applications were purely ‘container’ applications. Cloud Foundry makes the container-side of managing your ‘container’ application transparent. This approach ultimately lowers the tasks, breadth of tooling, and knowledge you have to surround Kubernetes with. It was with this thought, that a light-bulb went on.
