Introducing the Deterministic Construction Service (DCS) design pattern

How Codethink are using STPA for risk analysis of software-intensive systems and integrating the outputs into the engineering process.

For the last few months, the BuildTeam Community has been organising a meetup to gather like-minded community members to discuss, share and exchange innovations and relevant topics and systems in build.

Consuming open-source is only the start of the journey for many companies. Whether by design or necessity, organisations find themselves adapting from being simply open-source consumers to being full-fledged producers, contributors and maintainers, eventually working in public, following ‘open by default and ‘upstream first’ principles.

Codethink recently ran the Safety and Open Source devroom at FOSDEM 2021. Unfortunately, due to Covid-19, this was entirely virtual. However, this did make the conference more accessible to those who would otherwise be unable to attend. 2021 was the first year that the safety devroom had been run, and hopefully, it will become a regular occurrence at FOSDEM in future years.

In this episode of 'Meet the Codethings', we've asked Shaun about FOSDEM, the future of safety-critical software in automotive, and STPA. Keep up-to-date with our news about safety by just subscribing to our Safety newsletter at the end of the article.

FOSDEM is a two-day event organised by the FOSS community for FOSS the community. This event aims to gather like-minded professionals to learn, teach, and broaden their knowledge and network. This is a fun and exciting weekend for the developers and our employees since they are hosting their first devroom this year.

FOSDEM is coming, 6th and 7th of February 2021! In addition to attending the virtual event, this time Codethink engineers will be curating the Safety and Open Source Software Dev Room.

In our previous blog post we introduced the Interrogizer project. Interrogizer is a logic analyser, which means it samples binary signals and sends the samples to a host computer as fast as possible.

Interrogizer is an Open Source project, aimed at providing developers with an affordable and easily producible tool to aid troubleshooting by enabling measurement of digital signals. Started from a desire to share hardware knowledge around Codethink, the device uses a small microcontroller placed on a simple PCB that can be easily and cheaply produced; allowing for iterations of the product as development progresses.

In an evermore software-intensive world, the security of software systems has become a critical part of product design and implementation. One way in which attackers exploit software systems is by crafting malicious inputs. The defence to such attacks is a combination of defensive programming techniques including input validation.

In this post I'm going to talk about the recent tranche of work I've put into a tool I wrote called topplot, which plots graphs from the data produced by the system utility top.

Codethink is working on a project to design a fully open-source (hardware and software) research device for experimenting with shining light into skin and detecting the light that reflects, gets absorbed and passes through. This kind of technology is widely deployed for measuring heart rates.

In my previous blog post I introduced my work to improve Rust's support for RISC-V Linux systems. Since then I have fixed a couple of interesting compiler bugs. This blog post describes my process to track down these issues; explains some rustc internals; and discusses movement in the broader Rust community regarding RISC-V.

RISC-V is a new Instruction Set Architecture developed in the open and available for use without paying a license fee. This means there are no barriers to achieving open hardware implementations, which opens the door to performant (mostly) open hardware processors...

Medical Devices are utilising software more than ever before. Recent challenges from COVID-19 have outlined some of the great benefits of utilising open source within the Medical industry. Chris looks at the benefits Open Source Software and projects could bring to the industry, as well as potential drawbacks of implementing an open-source initiative

Codethink recently worked on platform libraries for the real-time M4 cores of the MediaTek MT3620, the first Azure Sphere chip certified by Microsoft focusing on the development of a set of drivers for the peripheral subsystems (SPI, I2C, I2S, ADC, PWM, GPIO and Timers).

Fortran will be turning 65 this November and, though the programming language may conjure up images of punch cards and room-sized computers, it is certainly not dead. Originally developed by IBM in the early 1950s for scientists and engineers, it found early success with the target audience and is still being used today.

Codethink’s culture stems from the world of open source software. A large part of what it means to be a Codething is taking part in the sharing of knowledge across the company and learning on a daily basis. This practice drives the development of understanding in different areas of …

Installing Linux on most PCs is easy — you pop in a DVD or a USB stick, click through the install process, and you’re most of the way there. When it comes to more specialised devices, however, installing and running an operating system isn’t quite so straight-forward.

Embedded devices …

Debian is over 20 years old now, and the venerable distro is keeping the ball rolling by releasing its latest version, 10.0 (Buster), last Saturday.

Free/Libre Open Source Software (F/LOSS) projects have always been community-driven affairs. Many of the tools that we use at Codethink are the result of years of passionate work put in by dedicated developers. They use their free time to provide the world with useful, thoughtful and creative software.

It is nearing the end of pride month, and over the course of June, here at Codethink we wanted to explore the question of inclusivity in the open source community. When we first wrote this article, we noted that the Wikipedia page on the matter was sparse, and we were surprised there was such a lack of detail. To address this, we contributed some of the research in this article, hoping to make it more easily accessible.

Here at Codethink we've recently been putting some energy into enhancing our onboarding process that we have in place for all new starters at the company. As we grow steadily in size, it's important we have a well defined approach to welcoming new employees into the company and introducing them …

Interview with Adam Jones discussing how to get into open source, and why Open source software is at the heart of Codethink.

For a project with one of our larger clients, Codethink engineers had been using a 3rd party debugging board, purchased by the customer. Engineers found that the debug board features were quite limited. Due to the delicate design of the board, the lead time for production was long and as …

The Civil Infrastructure Platform (CIP), a Linux Foundation Initiative, is attracting the attention of well known stakeholders in the Industrial Grade space.

The long term project goal is to create an Open Source base layer for industrial grade systems collaboratively to enable the creation of reusable building blocks that meet …

Over the course of three months and two PCB revisions, Codethink developed a USB 3 switch (See Image) in order to address issues regarding software deployment and continuous integration faced by one of our major customers.

Configuring Linux systems to stabilise latency

Over the course of the last few months, Codethink have conducted an investigation into whether or not Linux systems can be configured to be deterministic, so that performance over time is made to be more predictable and overall improved by tweaking the kernel in …

I attended GUADEC 2018, and really enjoyed it, and I feel that I got a lot out of it.

The talks were recorded and they should be put online some time soon, I think. They need volunteers to do some video editing first though.

There is an issue for doing …

Many embedded/automotive vendors are recommending that electronic control unit (ECU) consolidation can be best achieved by adopting an architecture with a hypervisor. The idea is to isolate functions into guest operating system virtual machines and restrict access to sensitive resources. So examples of the consolidated architecture look something like …
