Plasma Mobile Gear 21.12 is Out

The Plasma Mobile team is happy to introduce the Plasma Mobile updates for September to December 2021 Since its inception, Plasma Mobile has used the oFono stack for telephony functions (mobile data, calling, SMS), but with this Plasma and Gear release, we are transitioning our telephony stack to ModemManager. oFono is a Nokia/Intel project started in 2009 with the Nokia N900. It integrates with the higher-level ConnMan connection manager, and is currently used by projects like Ubuntu Touch and Sailfish, which maintain their own series of patches on top of the stack in order for it to work for their use cases. ModemManager is a FreeDesktop project started in 2008 with the goal of providing USB dongle support for desktops. It integrates with the higher-level NetworkManager network management daemon. It is currently used on Plasma Desktop and the GNOME desktop to provide support for USB modems, as well as on Phosh for telephony functions. Read more

  • Imagination introduces Catapult RISC-V CPU cores - CNX Software

    As expected, Imagination Technologies is giving another try to the CPU IP market with the Catapult RISC-V CPU cores following their previous unsuccessful attempt with the MIPS architecture, notably the Aptiv family. Catapult RISC-V CPUs are/will be available in four distinct families for dynamic microcontrollers, real-time embedded CPUs, high-performance application CPUs, and functionally safe automotive CPUs.

  • AS5600 support for moteus auxiliary encoders

    The initial implementation of auxiliary encoders for moteus supported exactly one encoder, the AS5048B. The hardware can support any I2C based encoder, so supporting additional encoders has always been on the TODO list.

    I’m excited to announce, that as of firmware release 2021-12-03, AS5600 encoders are now supported as well. They are a lot cheaper than the AS5048 as they have a much lower update rate and resolution, but that isn’t necessarily a problem if it is only used to disambiguate a modest gear reduction.

Catapult CPUs are also available in different families for dynamic microcontrollers, real-time embedded CPUs, high performance application CPUs, and automotive CPUs.

  • This system classifies different types of clouds using tinyML | Arduino Blog

    At the basis of each weather forecast is data — and a lot of it. And although the vast majority of atmospheric data collection is fully automated, determining cloud volumes and types are still done manually. This problem is what inspired Swapnil Verma to create a project that utilizes machine learning to categorize six different classes of clouds. The hardware for this system consists of an Arduino Portenta H7 due to its powerful processor and array of connectivity features, along with a Portenta Vision Shield for the camera. Both of these boards were mounted to a custom base on top of a tripod and powered by a battery bank over USB-C.

  • Use dmseg to check your Linux system's kernel message buffer | Network World

    The dmesg command displays the content of the kernel's message buffer since the system's most recent boot. It displays a lot of details on how the system is working and problems it might be running into that you won't normally see. That can be a lot of data, but there are several tricks for paring it down. For example, Even though the system queried below has only been up a little more than three days, it's collected more than a thousand lines of data.

  • Working with gnome-boxes - Unixcop the Unix / Linux the admins deams

    In my PC I’ve worked with Virtual box for years. Then virtual box, for some reason, was removed from the Debian repository.

Few months ago I need some virtual machines on my PC, so I began working with gnome-boxes.

  • How To Install Terminalizer on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Terminalizer on Ubuntu 20.04 LTS. For those of you who didn’t know, Terminalizer is a very useful terminal recording tool designed for different distributions of the Linux operating system. Terminalizer works in the same way as a desktop screen recorder but instead runs in your terminal. It has the capability to record all the activities that you perform on the Linux terminal and then save them in the form of an animated GIF. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Terminalizer on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to use monitoring to troubleshoot Ansible Automation Platform | Enable Sysadmin

    Running an Ansible automation controller in OpenShift provides an easy way to scale an Ansible automation controller. However, as with any virtualization platform, you need to enable the Ansible automation controller to run as efficiently as possible. Often, OpenShift runs on top of another virtualization platform, and understanding how resources are used at the various virtualization levels is essential. Overcommitting CPU and memory resources in your virtualization platform can impact OpenShift performance. Therefore, it is important to have a 1:1 commit ratio for CPU and memory in your virtualization platform and let OpenShift manage resource overcommitment. In addition to looking at CPU and memory overcommitment, you need to understand what other pods are running on the OpenShift instances in order to prevent resource conflicts. Proper management of OpenShift guarantees the availability of the Ansible automation controller and other applications running in the OpenShift environment. Quotas on namespaces set the maximum amount of CPU and memory resources a project can consume, limiting the impact one project can have on other projects. In addition, the request and limit settings for the task container set the CPU and memory resources the Ansible automation controller has for running jobs. By default, the Ansible automation controller installer sets the CPU request to 1,500 millicores and the memory request to 2GBs. You can use the task_cpu_request and task_mem_request variables to set request sizes for the task container in the Ansible automation controller installer inventory. These settings directly impact the number of forks an Ansible automation controller instance has available for running jobs.
