who we are

Jonni Bidwell More and more I find myself focusing on the not-so-smart things, so this is a really tricky question. I dunno though, Vernier calipers are pretty smart. Oh, and the people that do the Royal Institution lectures. Christian Crawley Sorting out the kids’ dance lessons, telling me where I need to be (and where to go) while working to resolve the concerns of residents as a local Councillor, the smartest thing in my life is without doubt my wife, Ceri. John Knight I don’t have any ‘smart’ gadgets at home, but I have ideas for an off-grid cabin powered by renewables. A collection of Raspberry Pis would be excellent for regulating power and lighting, and their low-power consumption would be perfect for computer usage without draining watts. Les Pounder The smartest thing in our home is…

control everything!

Sat up here in our ivory Linux Format Tower, it’s easy to pour scorn on those lesser non-Linux-using types, hopelessly switching their lights on and off with their phones, asking little round speakers what the weather is like outside their windows and checking if their milk has gone off by looking at their smart-fridge display. But why shouldn’t someone be able to remote-control their lights, control their heating or ask a system what the weather is in complete digital safety? We’re exploring how open source can solve the IoT problem by combining the Mycroft and OpenHAB projects to create a smart, secure voice-controlled open source home. Heck, it even ties into Google Home and Alexa, if that’s your thing. But digital Luddites of the world fret not, if having a smart home…

can meltdown and spectre bugs ever be fixed?

More than a year ago, the Meltdown and Spectre bugs were revealed to affect some of the most widely used processors in the world – and throughout 2018 and even into this year, new variants and threats based on the bugs have continued to be found. The vulnerabilities, which appear to be present in chips from nearly every manufacturer, enable potential malicious users to access protected data on a victim’s device, and exploit speculative execution and caching features of a CPU. While there have not been any known attacks using these vulnerabilities, their existence has caused shockwaves throughout the technology world – and beyond – due to the prevalence of the vulnerabilities. Since the revelations about the bugs were disclosed, a number of manufacturers moved quickly to release patches to mitigate the…

nginx acquired, rumours abound

Application services company F5 Networks has acquired Nginx for the princely sum of $670 million. Gus Robertson, CEO of Nginx, commented that “F5 shares our mission, vision, and values… they bring to bear a tremendous amount of additional resources and complementary technologies”, and assured Nginx customers that “F5 is committed to keeping the NGINX brand and open source technology alive. Without this commitment, the deal wouldn’t have happened for either side.” You can read his full statement at Any fears that F5 Network’s purchase will simply assimilate Nginx seem to be unfounded, with the Nginx brand remaining a separate entity. Robertson will join F5’s senior management team and continue to lead Nginx alongside Igor Sysoev and Maxim Konovalov, Nginx’s founders, while Nginx’s operations will continue at its existing offices in…

pureos embraces convergence

Purism, the team building the much-anticipated Librem 5 open-hardware smartphone, has announced that its open-source operating system PureOS will be a ‘convergent operating system’ that can run on both the smartphone and laptops. A few years ago, convergent operating systems like these seemed to be all the rage. While some software makers have dropped their convergence plans – most noticeably Canonical ditching its plans for a single version of Ubuntu to run on PCs, phones and tablets, back in 2017 – Microsoft, Apple and Google are all continuing to look at ways to have one OS on many devices. According to Jeremiah Foster, Director of PureOS, Purism has beaten its big competitors to the punch. In his blog post at, he says PureOS’s “future applications [will] run on both the Librem…

sharp openxr

“Just a few weeks ago at the Game Developers Conference (GDC) in San Francisco, the Khronos Group released the OpenXR provisional specification. And that same day, Collabora announced Monado, a free and open source XR platform, and first OpenXR runtime for Linux. OpenXR is an open standard that aims to unify and simplify the creation of experiences in augmented reality (AR) and virtual reality (VR), collectively known as mixed reality (XR). Monado enables applications and game developers to target GNU/ Linux without having to worry about hardware enablement. Monado also helps the hardware developers add support for their devices on GNU/Linux. My hope is that Monado becomes an ecosystem composed of key XR industry players and enthusiasts in the open source community. Going forward, my goal is to create a monthly update about our…
