Software Since my last post quite some progress has been made in getting KWin working on top of a Wayland compositor. My main focus of work has been on the input stack.

spooning, not forking

Software While other Free software projects drift apart, splitting up in multiple forks that stop talking to each other, differentiate based on the wrong reasons, what we see here during Akademy is projects growing closer to each other. This is a good development, so let’s look at it a bit more detailed.

KDE Manifesto: There and Back Again

Open Source Operating Systems for IoT

Over the past decade, the majority of new open source OS projects have shifted from the mobile market to the Internet of Things. In this fifth article in our IoT series, we look at the many new open source operating systems that target IoT. Our previous posts have examined open source IoT frameworks, as well as Linux- and open source development hardware for IoT and consumer smart home devices. But it all starts with the OS. In addition to exploring new IoT-focused embedded Linux-based distributions, I’ve included a few older lightweight distributions like OpenWrt that have seen renewed uptake in the segment. While the Linux distros are aimed primarily at gateways and hubs, there has been equivalent growth in non-Linux, open source OSes for IoT that can run on microcontroller units (MCUs), and are typically aimed at IoT edge devices.

New Cortex-M chips add ARMv8 and TrustZone

ARM launched its first Cortex-M MCUs with ARMv8-M and TrustZone security: the tiny, low-power Cortex-M23 and faster Cortex-M33. At the ARM TechCon show in Santa Clara, ARM unveiled two new Cortex-M microprocessors that will likely emerge as major Internet of Things workhorses over the coming decade, supplanting most existing Cortex-M designs. The Cortex-M23 and Cortex-M33 are also the first Cortex-M processors with ARMv8-M technology, enabling ARM TrustZone security, among other benefits. The TrustZone support is enabled via a new IoT-oriented CoreLink SIE-200 network-on-chip, which adds IP blocks on top of the AMBA 5 AHB5 interface. ARM also announced a TrustZone CryptoCell-312 technology for creating secure SoCs based on ARMv8-M. Read more

OpenStack in the Headlines

  • From OpenStack Summit, Red Hat Reports That the Deployment Era is Here
    As noted here yesterday, OpenStack is here to stay in enterprises. A new study by 451 Research analysts shows that about 72 percent of OpenStack-based clouds are between 1,000 and 10,000 cores and three fourths choose OpenStack to increase operational efficiency and app deployment speed. Meanwhile, in conjunction with OpenStack Summit in Barcelona, Red Hat is out with very notable results from its polling of its OpenStack user base. Its study found that production deployments increased hugely in the last year, according to a survey of 150 information technology decision makers and professionals carried out by Red Hat.
  • You can run the same programs on 16 different OpenStack clouds
    Cloud companies like to talk about about how you can avoid vendor lock-in. And OpenStack just showed how to make it happen. Sixteen different vendors did a live demo at OpenStack Summit showing that you could run the same software stack on 16 separate OpenStack platforms.
  • ​Where OpenStack cloud is today and where it's going tomorrow
    The future looks bright for OpenStack -- according to 451 Research, OpenStack is growing rapidly to become a $5-billion-a-year cloud business. But obstacles still remain.
  • ​Mirantis OpenStack: The good news and the bad news
    Mirantis recently signed a major deal with NTT, but the company is also laying off some of its employees.
  • The World Runs on OpenStack
    The OpenStack Summit keynotes got underway the morning of October 25, with Mark Collier, Chief Operating Officer of the OpenStack Foundation, declaring that the world runs on OpenStack.
  • Study: OpenStack is Marching Forward in Enterprises
    How fast is the OpenStack global cloud services market growing? Research and Markets analysts came out with a new report recently that forecasts the global OpenStack cloud market to grow at a CAGR of 30.49% during the period 2016-2020. Many enterprises now have large scale OpenStack deployments, and in conjunction with this week's OpenStack Summit in Barcelona, new study results are shedding light on exactly how entrenched this open cloud platform is in enteprises. The bottom line is: OpenStack is here to stay in enterprises. OpenStack deployments are getting bigger. Users are diversifying across industries. Enterprises report using the open source cloud software to support workloads that are critical to their businesses. These are among the findings in a recent study by 451 Research regarding OpenStack adoption among enterprise private cloud users. About 72 percent of OpenStack-based clouds are between 1,000 and 10,000 cores and three fourths choose OpenStack to increase operational efficiency and app deployment speed. The study was commissioned by the OpenStack Foundation. Here are some of the companies discussing their OpenStack deployments in Barcelona: Banco Santander, BBVA, CERN, China Mobile, Comcast, Constant Contact, Crowdstar, Deutsche Telekom, Folksam, Sky UK, Snapdeal, Swisscom, Telefonica, Verizon, Volkswagen, and Walmart. You can find some of the specific deployment stories from the companies at the OpenStack User Stories page.
