• Fixing Rust's test suite on RISC-V

    Article image

    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.

  • The challenges behind electric vehicle infrastructure

    In 2019, electric vehicles accounted for 7.4% of total passenger car registrations in the UK. For an ever-more environmentally conscious population, this presents a very low number. Electric vehicles are often seen as a next step, or even a solution for greener transportation. Indeed, electric vehicles are becoming a more accessible option for an increasing number of consumers, and getting closer to a wider public adoption.

  • Investigating kernel user-space access

    In 2018, Codethink worked with Lukas Bulwahn from BMW on a project investigating some core functionality of the Linux kernel that is relevant to safety considerations of an assumed system. We wanted to share some of our findings from this work, as it could prove useful to communities interested in using Linux in a safety-critical context.

  • Improving RISC-V Linux support in Rust

    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...

  • Creating a Build toolkit using the Remote Execution API

    Building and testing at scale often involves codebases with millions of lines of code, worked upon by thousands of developers. One solution to the problem of building as quickly as possible is simply delegating that responsibility — not to the machine that the developer is working on, or even to a server that the CI job has been dispatched to, but to a server farm...

  • Trusting software in a pandemic

    As concerns about the privacy and security implications of contract tracing apps for COVID-19 show, establishing trust in software is still a real challenge. I’ve been following reports about these apps closely, and have been interested to read medical, technical and ethical analysis from around the world. What all of these perspectives underline for me is the critical role of public trust in the success or failure of such applications.

  • My experiences moving to remote working

    I’ve now been working at home since early March. My colleagues and I have all adapted to be able to work at home following the coronavirus outbreak and the subsequent measures taken by the UK government and other governments around the world. This shift is one that we have all had to come to terms with quickly.
