Title: Analyze and fix your Large Software Architecture with Codevis
Abstract: Codevis is an open source tool that enables the user to study, analyse, and fix large scale software architecture flaws.
The software currently understands C, C++ and Fortran. Codevis’ main use case is to display relationship graphs between libraries, structures (such as classes or pure “c” structures), functions (including traits, functions or methods), and files. Codevis offers several tools that help find problems on large scale designs, such as a Knowledge Island (a visualisation that showcases who originates the source code per file, module, class) to find cycles.
Codevis aims to help corporations visualise all of their software architecture in one single tool. This ensures that faster and more confident action can be taken during development, or during architecture decision-making.
LLVM is a core part of this project for the C++ and Fortran parser. It has been proven to work. It fixes architectural issues within the KDE Frameworks Libraries - a collection of 80+ libraries combining millions of lines of code.

SOOCON24, London
Title: Testing in a Box: Streamlining Embedded Systems Testing with Open Hardware
Abstract: At Codethink we believe in testing hardware as early in the development lifecycle as possible, automating this testing makes it efficient and reproducible. We invariably need a number of connections to hardware devices for both development and automated testing which ends up with a birds nest of wires, dongles and peripherals, we put our minds to putting all of these together in one box containing a SBC, an open source USB switch, Can interface and an open source I/O board for everything else, including a USB hub, serial connection, GPIO switches, optocouplers and HID emulation.
This talk is about the concept, design and implementation of the Testing in a Box project along with some of the use cases that we're already using it for.

CES 2024, Las Vegas
Title: A Glimpse into the New Generation
Abstract: Electrification is the accelerant for connected electric vehicles and will bring an end to fossil fuel.
John explored:
- the role of software and technology in digitisation, demonetisation, democratisation
- what this looks like in a software-first organisation
- what this means for the automotive industry building ‘software defined vehicles’
- what this could lead to between now and 2050

Codethink proudly sponsored Advent of Code which took place between 1-25 December 2023.
"Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as interview prep, company training, university coursework, practice problems, a speed contest, or to challenge each other."
November 2023
SDV Europe, Berlin
Codethink proudly sponsored SDV Europe which took place between 26-28 November in Berlin.
SDV Europe is a conference that provided a forum for leaders across the automotive world to discuss the transition from hardware to software within the sector. Topics discussed included software architecture, DevOps, testing and validation, and much more.
Mini-DebConf, Cambridge
Title: A journey from kernel testing to testing Debian unstable
Abstract: Testing is an integral part of the software lifecycle. For software which are in continuous development it's even more important to have regular testing so that any bugs or errors can be detected early. In this talk, I will present how I started testing the Linux Kernel in a personal capacity and the status of Kernel testing that is now being done as part of Codethink. I will also present how that testing infrastructure has evolved to test Debian Sid on a RPI4 from a CI pipeline and the problems we had to overcome.
Watch the talk here.
October 2023
XDC Europe, A Coruña
Title: Automated graphical testing on real hardware: adventures with OpenQA
Abstract: OpenQA is a powerful testing tool developed originally for openSUSE and now used by various major distributions for integration testing. Within Codethink we're also using it to test mainline Linux on hardware across several CPU architectures and GPU stacks.
This talk will show how to create screenshot tests that can quickly verify your graphics pipeline is working. First I'll show how to quickly run the tests in a developer laptop using the QEMU backend. Then we'll look at a pipeline that builds a custom kernel and tests it on real hardware, using the same OpenQA testsuite.
September 2023
Embedded Recipes, Paris
Codethink proudly sponsored the 2023 edition of Embedded Recipes. Embedded Recipes brings together core developers and thought leaders to create a space for in-depth technical discussions and collaboration.
Kernel Recipes, Paris
This year was the 10th anniversary of Kernal Recipes which, Codethink proudly sponsored. Kernal Recipes is the informal conference covering all topics relating to the Linux kernal.
You can learn more about this event via the blog.
All Systems Go, Berlin Germany
Title: Building image-based OSes with BuildStream, in collaboration with Valentin David
Abstract: BuildStream is a tool for building / integrating software stacks. In a way, it has a similar goal to bitbake / yocto and Android repo, but takes a completely different approach. It can be used to take software from various sources, build it with various buildsystems in a reproducible sandbox, and cache results for speedy rebuilds.
This talk gives a brief overview of Buildstream, how it is used to build GNOME OS, and the challenges we face in using it. It also goes over freedesktop-sdk which is a base runtime that can be used as a base to build your own system.
It also discusses the challenges we encountered with using buildstream with ostree and the steps we're taking to support updating with systemd-sysupdate.
August 2023
Wuthering Bytes, Hebden Bridge, UK
The annual conference of the Open Source Hardware User Group, featuring talks and hands-on workshops covering a diverse range of topics related electronics, hardware hacking, open source, tools, techniques and more. A number of Codethings attended this event, as well as Codethink featuring as an event sponsor.
July 2023
GUADEC 2023, Riga, Latvia
Title: The best testing tools we've ever had: an introduction to OpenQA for GNOME
Abstract: How do you write the testsuite for an entire graphical desktop environment?
Desktop and distribution teams have been struggling with this question for more than a decade, and our combined efforts are starting to pay off. The combination of Gitlab, BuildStream, GNOME OS and OpenQA is the most powerful toolset we’ve ever had for ensuring high quality GNOME releases.
Akademy 2023, Thessanlonki, Greece
Title: An OSS Tool for Comprehending Huge Codebases
Abstract: Maintaining large C++ codebases with hundreds of developers is a complex problem.
In the KDE community, work is being undertaken to improve documentation, as well as to automate and systematize internal processes such as testing and QA (see current KDE Goals). Our tool, currently under development sponsored by Bloomberg, supports these processes, making it possible for developers to visualize and, therefore, better comprehend existing C++ architectures. This visualization, analysis, and development tool is based on the ideas from John Lakos' book "Large Scale C++ Software Design".
Our presentation has two parts. In the first, we explain how the ideas from John's book are implemented in the tool; in the second, we demonstrate how we've been using the tool to understand KDE projects, improve their code quality, and fix architectural suboptimalities.
June 2023
Embedded Open Source Summit, Prague
In June, a number of Codethings attended the Embedded Open Source Summit (EOSS) in Prague. It was a great event where those working on embedded open source projects and developer communities came together to collaborate and learn.

State of OpenCon
Title: "Automated testing with open source hardware", delivered by Mudit Sharma and Ben Dooks
Abstract: At Codethink we’re focused on automation and we’re focused on open source.
As part of our efforts to automate testing on embedded Linux projects (in our case, large automotive projects), we wanted to be able to programmatically switch between different USB ports. For example, to switch from an empty port to a port with a new system image, or to mimic plugging in a USB device such as a smart phone.
We couldn’t find a suitable, cost effective or open-source solution, so we decided to develop one ourselves.
In this talk we will introduce the USB Switch: a feature rich, bi-directional USB-C switch. We’ll go into detail on the features and the typical use cases.
AGL All Members Meeting
Title: OpenQA Testing on Hardware: Automated Full System Tests
Abstract: Testers on embedded projects lose time running and re-running the same manual tests, and some Automotive projects can require hundreds of people dedicated to manual testing.
Codethink has helped to automate end-to-end testing on hardware within a large automotive project using OpenQA and some additional custom tools.
In this talk, we will explain how it was done how it can be adapted for other projects, including AGL.
