  • OpenStack Charms 19.10 – Train, Policy Overrides and more

    This release introduces support for OpenStack Train on Ubuntu 18.04 LTS (via Ubuntu Cloud Archive) and Ubuntu 19.10. Train is the 20th OpenStack release which brings a lot of interesting features on its own. One of the most important additions are telco-specific extensions to Nova live migration. The benefits of moving guest machines from one hypervisor to another without shutting down the operating system of the guest are now also available in telco-specific environments with NUMA topology, pinned CPUs, SR-IOV ports attached and huge pages configured.

    In order to upgrade your Charmed OpenStack installation to Train, please follow the procedure described in the charm release notes.

    For more information about OpenStack Train, please refer to the upstream release notes.

  • Kafka Streams and How They Work

    Kafka streams seem like a daunting subject to many learners, but they don’t have to be. Just think of a stream as a sequence of events. In fact, when I put together information for this blog post, I joked that getting all this data would be like drinking from a waterfall. Chad (the Training Architect that created our new Kafka course) was able to take it a step further, and we went off on a tangent. This will help to explain it:

  • Kubernetes Documentation Survey

    In September, SIG Docs conducted its first survey about the Kubernetes documentation. We’d like to thank the CNCF’s Kim McMahon for helping us create the survey and access the results.

GNU/Linux on Tablets: Ntablet and Beyond

  • Ntablet Linux commercial open-source tablet from $225

    The Ntablet open source tablet has been created to provide developers, enthusiasts and hobbyists with a programmable learning platform offering an all in one device for creative projects. Watch the demonstration video below to learn more about the world’s first commercial open source tablet. Launched via Kickstarter this week and is now available with earlybird pledges from $225 or roughly £176, offering a 50% discount off the recommended retail price. Full goes to plan worldwide shipping of the open source tablet is expected to take place during March 2020 “As a portable tool, it gives not only convenience to your projects, but also help to create more innovative designs as what you imagine. With it, you can start programming and developing anywhere, you can freely DIY and control TV, air conditioner, curtain, light, and even Robot. Ntablet is also a Linux based tablet, the inside core-board and motherboard are connected in the way of the socket, which enables users to change the core-board anytime, to run different operating systems or applications, like Android and Linux. 20 pins and 4 pins sockets are designed on the motherboard, to be used to connect with GPIO board, users can do kinds of debug or control after connection.”

  • FieldKit Is The Grand Prize Winner Of The 2019 Hackaday Prize

    While some are still waiting for the age of the Linux desktop, this project moves past that and achieves an open design for a Linux-based tablet. Goals of the project focus on sidestepping the OS lock-in present in many consumer tablets, and delivering a hardware design that is both repairable and upgradable — traits currently absent in all consumer tablets. Recognized for Best Design, this project is awarded a cash prize of $10,000.

3D Subscription software driving move to open source

3D software makers' move to subscription models is pushing people to use open-source software because users are fed up with the price and neurotic terms and conditions. For a while now professional 3D software like 3DMax, Maya, AutoCAD (Autodesk) and Substance Painter (Adobe) are only available on a monthly or yearly subscription basis which means that you cannot get your paws on a perpetual license for these industry-standard 3D tools anymore, cannot offline install or activate the tools, and the tools also phone home every few days over the internet to see whether you have "paid your rent". This means if you stop paying your "rent" the software shuts down, leaving you unable to even look at any 3D project files you may have created with software. But this has created so much frustration, concern and anxiety among 3D content creators that, increasingly, everybody is trying to replace their commercial 3D software with Open Source 3D tools.

Intel: oneAPI and IWD 1.1

  • Intel Releases oneAPI Base Toolkit Beta For Performance-Focused, Cross-Device Software

    The oneAPI Base Toolkit is for writing code that runs across CPUs, GPUs, and FPGAs among other possible accelerators. The primary programming language is their Data Parallel C++ and SYCL fits into the toolchain as well. OpenMP and MPI are supported with the oneAPI HPC toolkit. While other components include the oneAPI IoT Toolkit for developing IoT software and the oneAPI rendering toolkit for ray-tracing and visual rendering. The different toolkits can be found here.

  • IWD 1.1 Released For Intel's Linux Wireless Daemon

    IWD 1.0 stabilized this wireless daemon's interfaces and made it ready for embedded and desktop use-cases as an alternative to the likes of WPA-Supplicant. With IWD 1.1 are just a few changes amounting to some basic fixes while the new feature is radio resource management.
