As Arm wanted to enter the server market, they realized they had to provide systems that could boot standard operating system images without modifications or hacks – just as they do on x86 server -, so in 2014 the company introduced the Server Base System Architecture Specification (SBSA) so that all a single OS image can run on all ARMv8-A servers.
Later on, Arm published the Server Base Boot Requirement (SBBR) specifications describing standard firmware interfaces for the servers, covering UEFI, ACPI and SMBIOS industry standards, and in 2018 introduced the Arm ServerReady compliance program for Arm servers.
While those are specific to Arm server, some people are pushing to implement SBBR compliant for Arm PCs, and there’s one project aiming to build an SBBR-compliant (UEFI+ACPI) AArch64 firmware for the Raspberry Pi 4.
Halloween is my favorite holiday! And to celebrate, here are 7 great retro games that are perfect for the occasion. These are some great spooky-fun games to add to your RetroPie.

Autumn is just around the corner. For many participants in the GSoC 2020, a busy and instructive summer full of hacking on open source projects came to an end a few weeks ago. Commits have been contributed and final reports have been written. This year experienced Collabora Productivity developers were again mentors for various projects of the Google Summer of Code for the LibreOffice project. Here are some examples of projects our team helped to succeed!
OpenBehavior is an open-source repository for tools, software, projects and scripts that are dedicated for behavioral neuroscience research.
The main goal is to promote and accelerate the collaboration of open-source neuroscience projects, neuroscience researchers and developers.
Currently, OpenBehavior has 145 projects and active community of developers and research who are supporting this project. The project is founded and maintained by a group of researchers and professors. It started 2016 by Mark Lubach (PhD) and Alexxai Karvitz (PhD).
The project is funded by NASA DC Space Grant Consortium to ML, Summer 2017. However, It's still looking for more support as it's 100% volunteer work.
This is a deep-dive into some of the implementation details of Taskcluster. Taskcluster is a platform for building continuous integration, continuous deployment, and software-release processes. It’s an open source project that began life at Mozilla, supporting the Firefox build, test, and release systems.
The Taskcluster “services” are a collection of microservices that handle distinct tasks: the queue coordinates tasks; the worker-manager creates and manages workers to execute tasks; the auth service authenticates API requests; and so on.
VM Brasseur explains open source “drive-thru contributions” and explores how the process can be improved.
In the ongoing efforts to create a sustainable free and open source software ecosystem—one where projects receive the attention they need without burning out their maintainers in the process—a lot of attention has justifiably fallen on increasing the number of FOSS contributors.
Much of the discussion around increasing contributors assumes that the primary goal is to get contributors who will stick around and become community members and maintainers. It's certainly true that many hands make light work, and the more maintainers a project has the less likely it is that any one of them will bear the brunt of the work and burn out. But, this isn't the only way to support project sustainability through contributions. Another approach is to optimize your project for drive-thru contributors.
Security updates have been issued by Debian (linux-4.19), Fedora (tcpreplay, xen, and yubihsm-shell), SUSE (pacemaker), and Ubuntu (gosa and pam-python).
The job of a print server is to accept print requests from multiple machines, process those requests, and then send them to the specified printer for serving those requests. CUPS is a utility designed for Linux operating systems that can turn a regular computer system into a print server. This article provides a method for setting up the CUPS print server in Ubuntu 20.04.
This tutorial explains how to switch Ubuntu 20.10 user interface back to Unity rather than GNOME. This is for computer users who prefer Ubuntu with its innovative Unity appearance that found in version 10.04 LTS and 16.10. Now let's have fun!
When I started Purism in 2014 I knew I wanted to build secure computing hardware bundled with a privacy-respecting operating system that had freedom-respecting applications and services. I also knew that a computer could be a server, desktop, laptop, tablet, phone, watch, among many other form factors, and most of these have screens or at least a screen used to interact with (until we get to read/write electrical signals in our brains–what I call brain embeddables, sci-fi terminology sometimes calls “beddies”–we will continue to see devices with screens).
In early 2005 (when I started the first online cable company) I presented that the movie and television industry needed to look at all computers as TVs, since a TV is just a computing device showing videos on a screen, and the only difference was size of screen, distance to viewing, and user interaction. A “TV” in that sense was remote controlled from a couch, a laptop was keyboard and mouse controlled from close-up, a tablet and phone (realize this was 2005 so pre-smartphone) could also become a video device. All of these are “just screens” from my point of view.
Forming Purism, I knew we would iterate from laptop toward phone; but also could include servers (with monitor), desktops (with monitor), tablets, watches, routers, and all sorts of brainstorm-worthy products–nearly all containing a screen or access via a screen. It was very easy for me to “just use a screen” as a logo, and in what is probably a very rare story, I drew the first logo which was the only logo and remains our logo to this day. A simple rectangle to reference that all these screen based devices are just computers and with them we can do anything we desire.
YOLOv3 is out now through the compiler framework and we can expect it to be demonstrated in the coming weeks. By Q1 2021, it will support popular customer models and initial support for Linux-based operating system Ubuntu and CentOS.
We’ve previously covered or even tested STMicro Time-of-Flight (ToF) ranging sensors with devices like VL53L0X with up to 2-meter range or VL53L1X extending the range to a maximum of 4 meters to measure the distance to one object aka region of interest (ROI).
Real-Time Patches Updated For Linux 5.9/5.10 With The Code Not Yet Mainlined
There was talk earlier this year of mainlining the real-time Linux kernel patches after similar discussions last year didn't result in it happening. Merging the RT code didn't happen for the recent Linux 5.10 merge window but at least the out-of-tree patches were quickly re-based for Linux 5.9 stable and 5.10-rc1.
Sebastian Andrzej Siewior announced today 5.9.1-rt20 and 5.10-rc1-rt1 as the latest real-time patches for the current stable and development kernels.
Also: [ANNOUNCE] v5.9.1-rt20

The latest versions of Red Hat Software Collections and Red Hat Developer Toolset are available now in beta. Red Hat Software Collections 3.6 delivers the latest stable versions of many popular open source runtime languages, web servers and databases natively to the world’s leading enterprise Linux platform. These components are supported for up to five years, helping to enable a more consistent, efficient, and reliable developer experience.
Red Hat Enterprise Linux (RHEL) 8.3 will be available in the coming weeks. In this post we'll take a look at some of the highlights and important new features that are planned for RHEL subscribers.
A RHEL release has many constituencies. RHEL has to meet the needs of system administrators who crave system stability and predictability, and developers who want flexibility and new language and software choices. With new system roles, a major RHEL container tools update, cloud administration updates and more, RHEL 8.3 delivers for those who depend on enterprise open source to run today's businesses.
The third update since RHEL 8's release in early 2019, RHEL 8.3 continues the six-month cadence of minor releases. By offering a predictable, time-based release cycle we help drive new features in a timely fashion without compromising the reliability of RHEL that our users and customers depend on.
JDK Flight Recorder, or JFR, is an event-based production environment profiler available from OpenJDK 8u272 forward. Being a HotSpot-native feature, JDK Flight Recorder performs with extremely low overhead in terms of how it uses both space and time.
While JDK Flight Recorder collects basic Java runtime information by default, it is also possible to use JFR’s Event API to collect custom events. Developers who want to collect application-level events must actively define and instantiate them in their application source code.
In this article, we’ll show you how to use JMC Agent and the JMC Agent Plugin to instrument your application classes with event-emitting code. When you use JMC Agent with the JDK Flight Recorder Event API, you do not need to shut down the JVM and recompile the application code.
We continue to update the Red Hat Integration product portfolio to provide a better operational and development experience for modern cloud– and container-native applications. The Red Hat Integration 2020-Q3 release includes Red Hat 3scale API Management 2.9, which provides new features and capabilities for 3scale. Among other features, we have updated the 3scale API Management and Gateway Operators.
This article introduces the Red Hat 3scale API Management 2.9 release highlights, including air-gapped installation for 3scale on Red Hat OpenShift and new APIcast policies for custom metrics and upstream mutual Transport Layer Security (TLS).
StereoPi is going to Crowd Supply to pitch an open-spec “StereoPi v2” stereoscopic camera board that works with the Raspberry Pi CM4. The v2 adds a Type-C port and advances to GbE and 802.11ac.
In Dec. 2019, Russia-based Virt2real found Crowd Supply success with a StereoPi stereoscopic camera board that works with the Raspberry Pi Compute Module 3 (CM3). Now operating under the StereoPi name, the company has posted a Crowd Supply page for a second-gen model that uses the new Raspberry Pi CM4.
8 Tools to Easily Create a Custom Linux Distro
When there are so many Linux distros out there, you are probably wondering why someone would want to create their own distro instead of getting a readymade one. While in most cases a readymade distro is fine, if you want to have a distro that is 100 percent tailored to your needs (or your mum or dad’s needs), you may have to create your own custom Linux distro.
With the right tools, creating your own Linux distro isn’t as hard as it seems, though it takes time for sure. There are many tools for the purpose – some of them are universal, and some of them are distro-specific. Here are eight of them.
