During 10 years of working with technical sales of Industrial Linux systems I have often been meet with a somewhat religious technical discussion about "which" Linux to use and currently the discussion is normally Debian vs. Yocto based Linux.
This white paper have been made primarily for managers, sales and purchasers regarding the overall (and not to technical deep) differences between Debian and Yocto based Linux usage in industrial applications.
The content of the white paper is build on the my and my colleagues own experiences, based on development of more than 100 Industrial Linux solutions and probably discussion of more than 250 Linux solutions with customers over a period of 10 years at Prevas A/S.
Jonathan Corbet - Keynote: The Kernel Reportlinuxlab_conf
A whirlwind tour of what has been happening in the kernel development community and what can be expected in the near future.
The Linux kernel is at the core of any Linux system; the performance and capabilities of the kernel will, in the end, place an upper bound on what the system as a whole can do. This talk will review recent events in the kernel development community, discuss the current state of the kernel and the challenges it faces, and look forward to how the kernel may address those challenges. Attendees of any technical ability should gain a better understanding of how the kernel got to its current state and what can be expected in the near future.

Automotive Grade Linux on Raspberry Pi: How Does It Work?Leon Anavi
Talk by Leon Anavi at Embedded Linux Conference North America 2020
Automotive Grade Linux (AGL) is a leading embedded Linux distribution for the automotive industry. The AGL Unified Code Base (UCB), using the Yocto Project and OpenEmbedded, has been already adopted by automotive manufacturers and it is present in vehicles like Toyota Camry and all-new 2020 Subaru Outback and Subaru Legacy.
Since 2016 AGL has been ported to Raspberry Pi which nowadays is a prefer getting started platform among the community. The presentation will explore the current status of AGL on Raspberry Pi, reveal war stories and practical experiences for supporting Wayland, PipeWire, libostree for software over the air updates as well as various hardware peripherals.
Guidelines and step by step instructions for building AGL image for Raspberry Pi will be revealed. We will do a deep dive in internals, such as integration of meta-raspberrypi BSP layer, Linux kernel and Mesa versions with firmware KMS to support both HDMI and the official Raspberry Pi touch screen DSI display.
The talk is appropriate for anyone, including beginners. No previous experience is required. Hopefully, the presentation will encourage more people to try AGL on Raspberry Pi and join our community.
Running Android on the Raspberry Pi: Android Pie meets Raspberry PiChris Simmonds
You can run Android on a wide range of devices, not just phones and tablets. Building Android from scratch is fun and a great way to learn about the lower levels of the operating system. Imagine - here is a chance to create ANY Android configuration you want.
In this presentation, I will show you how to take a Raspberry Pi 3 and build Android completely from scratch, using source code from the AOSP (Android Open Source Project). We will need a few things to make this work A Linux kernel that has been configured with the options that Android expects OpenGL ES graphics drivers HAL layers for graphics and networking, amongst other things
Comparison of Open Source Software Home Automation ToolsLeon Anavi
With the market grow of Internet of Things the demand for open source home automation software for controlling numerous connected appliances also increases. Open source solutions allow users to customize the setup depending their own specific needs and to manage devices manufactured by different vendors in one place.
This presentation will provide an overview of the popular open source tools for home automation and focus on some of the most popular among them: Home Assistant, OpenHAB and Domoticz. We will explore the supported embedded Linux development boards on which these platforms can be installed as well as the IoT with which they can interact out of the box. Practical examples for simple home automation will be provided.
The talk is appropriate for open source enthusiasts, makers, engineers, students and even beginners. No previous experience is required.
Software update for IoT Embedded World 2017Chris Simmonds
Many embedded Linux projects have a requirement to update the software on devices in the field. Recent security flaws in basic components such as OpenSSL and bash, combined with the interconnectedness of all things, have highlighted the problem and made it an absolute necessity
Bugs happen. Identifying and fixing them is part of the development process. This tutorial demonstrates one of the key tools in the embedded Linux developer’s toolbox: the GNU Debugger, GDB.
You will begin by using GDB to debug a program running on a target device. You will learn about debug symbols: how build them into programs and libraries, and the places that GDB will go looking for them. Next, you will perform basic debugging tasks, including setting breakpoints, stepping through code, examining variables and modifying variables. After that you will lean about GDB command files and how they can help you by automating certain tasks. You will receive a handy GDB cribsheet to help you with all of this. If time allows, we will discuss how to use GDB to analyse core dumps so that you can perform a post-mortem on a crashed program
The Yocto Project and OpenEmbedded are often used for building custom GNU/Linux distributions for powering interactive kiosk and displaying HTML5 content.
Although Chromium is the most popular choice for a web browser, it is infamous for the long build time. In this presentation you will see a practical alternative approach using the surf web browser. Surf is a simple minimalist web browser based on WebKit2/GTK+ with interface that does not include any graphical control elements. It a perfect fit for a kiosk.
The presentation will offer the exact steps how to build a minimal GNU/Linux distribution with systemd, X11, openbox window manager and the Surf web browser. Furthermore, we will discuss practical examples for software over air updates of this simple distribution. Raspberry Pi 4 will be used as a reference hardware for all demonstrations.
This presentation is suitable for beginners. It will demonstrate a practical use of the Yocto Project/OpenEmbedded for a common use case, some tips and tricks as well as examples for selection systemd as init system and software over the air mechanism.
I had a chance to talk about the history and other interesting tidbits about the LibreOffice project at the Triangle C++ Developer's Group, and here is my slides.

Making Open Source Hardware for Retrogaming on Raspberry PiLeon Anavi
Raspberry Pi, the most popular single board computer for hobbyists and students, is an affordable and widely used platform for retrogaming. Over the years the community has created numerous cool cases, add-on boards and peripherals for optimized gaming.
In this presentation you will learn how to use cutting edge free and open source technologies such as KiCAD and OpenSCAD to create a gamepad as a Raspberry Pi HAT (Hardware Attached on Top) with device-tree fragment for mapping the keys saved in an EEPROM connected via I2C. Exact steps for setting it up and playing retro games in emulators on RetroPie and Raspbian will be provided. Furthermore we will discuss the benefits of the open source hardware and the certification program of Open Source Hardware Association (OSHWA).
The presentation is appropriate for anyone interested in low-cost retrogaming and modern free and open source software technologies. No previous experience or hardware knowledge is required. Apart from retrogaming enthusiasts, the talk is appropriate for wide range of developers, makers, and students. Hopefully, the presentation will encourage the attendees to grab the soldering iron and start prototyping retrogaming compatible hardware for fun and profit.
Presented by: Elizabeth Joseph, IBM
Presented at All Things Open 2020
Abstract: Many enterprises and, as many of us learned during the COVID-19 outbreak, governments, rely on mainframes to do the bulk of their data-driven work and the modern mainframe is very good at what it does. But what if you’re looking to modernize your platform and bring in the DevOps methodologies, tooling, and practice into your organization?
Today, there is an entire product line of mainframes that exclusively run Linux (RHEL, SLES, or Ubuntu). With Linux, you get access to the vast ecosystem of open source software that’s already been ported to the mainframe architecture (s390x), with more being ported every month.
If your organization is using z/OS, the Open Mainframe Project has a series of open source projects targeted specifically at the mainframe and improving usability. Zowe, for instance, helps create a consolidated API for accessing resources and workload on your system and Feilong is a z/VM connector that allows you to manage your virtual machines with familiar open source tooling like OpenStack. There are even connectors for Jenkins that allow you to integrate CI/CD pipelines with your workloads.
In this talk I’ll explore all of this in more to show you how an automated, modern environment can thrive on today’s mainframe.
This presentation was used during a lecture I delivered in Hive Pilani 2015 on Firefox OS and Firefox OS App Development for newbies.
The presentation aims to educate the audience enough to smooth the move to actual Firefox OS Development. The presentation therefore covers topics such as - Architecture, Bootstrap Process, Layer View of the OS etc.
2. HAIKU O/S Haiku is a freeopen sourceoperating system compatible with BeOS. Its development began in 2001, and the operating system became self-hosting in 2008,[2] with the first official alpha version released in September 2009 and the second Alpha release in May 2010.
3. HISTORY OF O/S Main article: History of Haiku (operating system) Haiku began as the OpenBeOS project in 2001, the year that Be, Inc. was bought by Palm, Inc. and BeOS development was discontinued; the focus of the project was to support the BeOS user community by creating an open-source backward-compatible replacement for BeOS. The first project by OpenBeOS was a 2002 community-created "stop-gap" update for BeOS 5.0.3. In 2003, a non-profit organization (Haiku Inc.) was registered in Rochester, New York to financially support development, and in 2004, after a notification of infringement upon Palm's trademark on the BeOS name was sent to OpenBeOS, the project was renamed as Haiku. Development, however, would only reach its first milestone in September 2009 with the release of Haiku Alpha 1. This very first release was followed by Alpha 2 R1 released in May 2010 which contains more than 300 bug-fixes/improvements.
4. DEVELOPMENT Haiku is developed in C++ and provides an object-oriented API. The modular design of BeOS allowed individual components of Haiku to initially be developed in teams in relative isolation, in many cases developing them as replacements for the BeOS components prior to the completion of other parts of the operating system. The original teams developing these components, including both servers and APIs (collectively known in Haiku as "kits"), included: App/Interface – develops the Interface, App and Support kits. BFS – develops the Be File System, which is mostly complete with the resulting OpenBFS Game – develops the Game Kit and its APIs. Input Server – the server that handles input devices, such as keyboards and mice and how they communicate with other parts of the system. Kernel – develops the kernel, the core of the operating system. Media – develops the audio server and related APIs. MIDI – implements the MIDI protocol. Network – writes drivers for network devices and APIs relating to networking. OpenGL – develops OpenGL support. Preferences – recreates the preferences suite. Printing – works on the print servers and drivers for printers. Screen Saver – implements screen saver functionality. Storage – develops the storage kit and drivers for required filesystems. Translation – recreates the reading/writing/conversion modules for the different file formats.
5. COMPATIBILITY WITH BeOS Haiku aims to be compatible with BeOS at both the source and binary level, allowing software written and compiled for BeOS to compile and run without modification on Haiku. This would provide Haiku users with an instant library of applications to choose from (even programs whose developers were no longer in business or had no interest in updating them), in addition to allowing development of other applications to resume from where they had been terminated following the demise of Be, Inc. This dedication to compatibility also has its drawbacks though, requiring Haiku to use version 2.95 of the compiler GCC, which is 9 years old.[4] Switching to using the newer GCC version 4 breaks compatibility with BeOS software, therefore Haiku supports being built as a hybrid GCC4/GCC2 environment.[5] This allows the use of both GCC version 2 and version 4 binaries at the same time. Note this compatibility is only valid for x86 systems. The PPC version of BeOS R5 will not be supported. As a consequence, the ARM, 68k and PowerPC ports of Haiku use only the gcc4 compiler. Despite these attempts, compatibility with a number of system add-ons which use private APIs will not be implemented. These include additional filesystem drivers and media codec add-ons, although the only affected add-ons for BeOS R5 not easily re-implemented are Indeo 5 media decoders for which no specification exists. Driver compatibility is incomplete, and unlikely to cover all kinds of BeOS drivers. 2D graphics drivers in general work exactly the same as on R5, as do network drivers. Moreover, Haiku offers a source-level FreeBSD network driver compatibility layer, which means that it can support any network hardware that will work on FreeBSD. Audio drivers using API versions prior to BeOS R5 are as-yet unsupported, and unlikely to be so; however, R5-era drivers work.
6. Haiku Anew operating system inspired by BeOS Haiku is an open source operating system that specifically targets personal computing. It is inspired by the now defunct BeOS and reimplements both the BeOS technologies as well as the end user experience. Recently the Haiku team unveiled the first release candidate RC1 by releasing a liveCD of Haiku R1 Alpha1.The Haiku R1 Alpha1 live CD ISO is only 380MB in size. Succumbing to curiosity, and because of its tiny size, I downloaded Haiku live CD and took it for a run. Simply put, I was really impressed with the user interface and the stability of the OS. I found the Haiku Desktop interface to be unique providing a radical approach to desktop computing.Haiku live CD at present is more of a showcase and has little applications to be of any use to the lay person. However, it does bundle with it the Firefox web browser though. One thing which impressed me was the smoothness with which some of the demo OpenGL applications ran - even in a Virtual environment. Below are a few images of the Haiku operating system for your peruse
8. If you haven't heard of Haiku by now, it's probably for good reason: as of a year ago, the OS could barely connect to the internet, and certainly wasn't anywhere close to replacing your Linux build of choice. Luckily the open source replacement for the gone-but-not-forgotten BeOS of yore is maturing nicely, and it just had a bit of a coming out party at the Southern California Linux Expo this last weekend. There are still plenty of glitches to iron out, with applications like Firefox crashing and glitching frequently, and a shortage of hardware support, but the core elements of BeOS are there and just as lovable as ever. For instance, that few second start time never gets old, same for that 60MB disk image, and the most excellent processor utilization. Check out the in-depth preview on Ars for a better idea of the past future (or is it future past?) of operating systems, or just download the latest nightly on Haiku to find out for yourself.

10. Haiku Podcast was founded in April 2006 by Sikosis. I'd been toying around with the idea of doing a podcast for awhile and then one day it dawned on me, what better subject to talk about than Haiku ... ... and what is Haiku you ask ? Haiku is an open-source desktop operating system focusing on usability, innovation, and speed. The first release will be an improved version of BeOS R5, but the team have completely new ideas for the future. Development is currently underway and making steady progress towards its first release.
