First Look at MX Linux Fluxbox on the Raspberry Pi 4

MX Linux Fluxbox-RaspberryPi Respin is MX Linux’s first attempt to offer an AArch64 (ARM64) port for the Raspberry Pi single-board computer. The work is done by Jerry Bond and others, and let me tell you that it’s one of the best Linux on Raspberry Pi experiences I’ve tried so far in terms of performance and usability. I’m not a fan of the Fluxbox window manager, but I understand why Jerry Bond choose it as default graphical environment for this Raspberry Pi spin of MX Linux. It’s super fast and consumes very few resources. For example, the RAM usage is always around 300MB (without any apps running), and that’s very important for older devices, such as a Raspberry Pi 3 with 2GB RAM. Read more

  • CloudLinux expands its Extended Lifecycle Support services for Linux distributions

    CloudLinux announces the expansion of its affordable Extended Lifecycle Support (ELS) services for Linux distributions, by providing its own updates and security patches for several years after expiration of the products’ end-of-life date. For example, support for CentOS 6 from Red Hat expired November 30 last year. CloudLinux offers ELS for CentOS 6, available since November, 2020 and extends to June 2024. Oracle Linux 6 (ends March 2021) Extended Lifecycle Support service will be available starting in February 2021 and will extend to February 2025. Extended Lifecycle Support service for Ubuntu 16.04 (ends April 2021) and Debian 9 (ends June 2022) is under development.

  • Moving your applications to the cloud with Red Hat Enterprise Linux

    Red Hat Enterprise Linux (RHEL) is widely deployed on-premise to run a variety of applications, but more conservative customers may need guidance in taking their first steps toward the cloud. One of the features in RHEL 8.3 is Image Builder’s Push to Cloud capability, which can help simplify and accelerate the transformation of workloads to the cloud. Building custom images is just one way to deploy RHEL for your enterprise. [...] RHEL provides a stable, manageable platform for applications for architects, operations, developers. Though some organizations may be hesitant to deploy an open source OS, RHEL is a supported solution, and there are ways to give it a try.

  • Red Hat OpenShift Container Storage 4.6 Offers New Data Resilience Capabilities

    Red Hat OpenShift Container Storage 4.6 helps enterprises expand their existing data protection capabilities to include Kubernetes applications, without requiring additional technology or infrastructure upgrades. Red Hat OpenShift Container Storage 4.6 delivers snapshot functionality orchestrated by the Container Storage Interface (CSI) for customizable, point-in-time snapshots and clones of persistent data volumes. This makes it easier for IT administrators and application developers to more quickly return to a prior state.

  • Elastic Deep Learning in high performance multitenant cluster

    The Elastic Deep Learning capabilities of IBM Watson® Machine Learning Accelerator are designed for large-scale distributed deep learning workloads. It transforms static monolithic training into a dynamic process that is resilient to failures and automatically scales GPU allocation while training. Data scientists, deep learning developers, and administrators can use Elastic Deep Learning capabilities to simplify production deployment, improve run time efficiency, and deliver on service level agreements (SLAs).

  • How to Install Webmin on Fedora Linux

    Keeping an eye on your system’s performance is one of the essential tasks that any Linux user should undertake from time to time. This helps in diagnosing any bottlenecks that are likely to impact performance. Webmin is a free and open-source front-end monitoring and administration tool that helps Linux users have a glance at various system metrics and perform administration tasks without the need of running commands on the terminal.

Ubuntu: Design and Web, Kubernetes, and More of Canonical

  • Design and Web team summary – 27th January 2021

    The web team here at Canonical run two-week iterations. Here are some of the highlights of our completed work from this iteration.

  • Canonical & Kubernetes: 2020 highlights

    We’re now well into 2021, and as we plan ahead for our roadmap and activities around Kubernetes for the year, it helps to look back and reflect on everything that took place for Canonical in the K8s space within the year that passed. Kubernetes has always been a crucial part of Canonical’s vision and contribution to the IT world. All leading cloud providers, such as Google, Microsoft, Amazon, Cisco and IBM run cloud Kubernetes services on Ubuntu, because we focus on the latest container capabilities in modern kernels. This focus is why Ubuntu is also the top choice for on-premises enterprise Kubernetes, with MicroK8s, kubeadm and Charmed Kubernetes all supported by Canonical.

  • Magewell HDMI Capture with ffmpeg ·

    On Linux, no additional driver is needed. When attached to a USB port the Magewell device shows up under /dev/video* on Linux. There’s a few software options available to capture the stream including VLC and OBS, but I prefer to use a little script. I call it make_screencast and it lives in my /home/alan/bin folder, on the machine capturing the video. The script is below.

  • EasyOS Dunfell 2.6.1 released for the Raspberry Pi4

    The very first release of EasyOS Dunfell-series for the Raspberry Pi4 was version 2.6, released on January 19. See announcement: https://bkhome.org/news/202101/easyos-dunfell-26-released-for-the-raspberry-pi4.html Since then, some package version bumps: SeaMonkey is now version 2.53.6 and includes the IRC chat module, ffmpeg is 4.3.1. LibreOffice is still a somewhat old version, 7.0.1.2, but I recompiled it with PDF-import support, which seemed like a good thing to have. Version 2.6.1 also has Samba, which had been left out of 2.6. Also added package 'smbnetfs'. Oh yes, also added package 'tigervnc', that Forum member rufwoof reported as very fast. Added package 'libvdpau-va-gl' though don't really know why. There were some performance issues with 2.6, that have mostly been fixed. SeaMonkey was often temporarily freezing, which seems to have been fixed by changing to 'kyber' IO scheduling. Plugging in a USB-stick, the kernel now consistently recognizes it first go -- due to version bump of the kernel from 5.10.4 to 5.10.9 and update of the device-tree.

  • Build a programmable light display on Raspberry Pi | Opensource.com

    This past holiday season, I decided to add some extra joy to our house by setting up a DIY light display. I used a Raspberry Pi, a programmable light string, and Python. [...] Each light can be individually programmed using an RGB set of integers or hex equivalents. These lights can be packaged together into matrices, strings, and other form factors, and they can be programmatically accessed using a data structure that makes sense for the form factor. The light strings I use are addressed using a standard Python list. Adafruit has a great tutorial on wiring and controlling your lights. [...] The neopixel_controller Flask application, in the neopix_controller directory of the github repository (see below), offers a front-end browser graphical user interface (GUI) to control the lights. My raspberry pi connects to my wifi, and is accessible at raspberrypi.local. To access the GUI in a browser, go to http://raspberrypi.local:5000. Alternatively, you can use ping to find the IP address of raspberrypi.local, and use it as the hostname, which is useful if you have multiple raspberry pi devices connected to your wifi.
