  • Small computers find an industrial niche

    When Eben Upton developed the Raspberry Pi in 2012, he expected the no-frills, single-board computer to appeal mainly to schoolchildren. Consumers had other ideas. Margaret Harris spoke to him about how simple computers like the Raspberry Pi are becoming integral parts of the emerging industrial Internet of Things

  • Once a physicist: Eben Upton

    In my first year at Cambridge, the course was around 25% computer science, 25% physics, 25% materials science and 25% maths for physics. I enjoyed the experimental parts of the course, and especially the weekly sessions at the Cavendish lab. But the second year was two lots of physics, plus maths for physics, and after that it became clear that I was an engineer more than I was a physicist, so I moved across to engineering.

Zink Benchmarks - Mesa OpenGL Running Over Vulkan

With the upcoming Mesa 19.3 release one of the big new features is the "Zink" driver that provides a Mesa OpenGL implementation over Vulkan. This in theory allows for a generic OpenGL driver running over Vulkan hardware drivers, but there is a lot of work ahead before it's really a viable option. Zink is one of the OpenGL-over-Vulkan options to date that in the future could make it so hardware vendors don't need to maintain OpenGL drivers for future hardware generations but instead could just focus on Vulkan and leave it to these generic implementations. However, a lot of work is needed before it's really to that state in being able to replace existing hardware OpenGL drivers. With Mesa 19.3, Zink only fully supports OpenGL 2.1. Support for OpenGL 3.x/4.x and OpenGL ES 3.0 is still a work-in-progress likely taking at least a few months to get there if not longer. When trying to launch even the Steam client with Zink, Steam was simply crashing. Read more

Compact Ryzen V1000 system starts at $689 with pre-loaded Ubuntu

Simply NUC’s compact “Sequoia” computer features a quad-core Ryzen Embedded V1000, 0 to 60°C support, and an 8-32V input.

  • Monitoring Bandwidth On Linux: Top 5 Tools in 2019

    Don’t we all wish our networks had infinite bandwidth? The reality is, however, that it is often a severely limited resource. Add to that the fact that bandwidth over-utilization can have huge impacts on network performance and we have a recipe for disaster. The solution: set up some bandwidth monitoring system. A lot of them are available. Most of them run on Windows, though, and if your OS of choice it Linux, your options are slightly more limited. You still have plenty of options, however, and we’re about to introduce the best tools for bandwidth monitoring on Linux. We’ll begin by introducing bandwidth monitoring and explain what it is. Next, we’ll cover the ins and outs of the Simple Network Management Protocol, or SNMP, one of the most-used monitoring technology. Our next order of business will be to have a look a Linux as an operating system but, more specifically, as a platform for monitoring tools. And finally, we’ll briefly review some of the best tools for bandwidth monitoring on Linux and describe their best features.

  • Bangle.js — A Hackable Smartwatch Powered By Google’s TensorFlow

    The world of smartwatches is ruled mostly by the likes of Apple Watch and WearOS-based devices. But we have seen a few attempts from the open-source community, including PineTime and AsteroidOS. Now, the tech world has got something new to play with — an open-source hackable smartwatch called Bangle.js. It’s co-developed by NearForm Research and Espruino, which showcased its latest offering to the attendees of the NodeConf 2019. Until now, the two companies provided digital badges at the conference.

  • Can Google’s New Open Source Tool Make Kubernetes Less Painful?

    Google has pushed Skaffold – a command line tool that automates Kubernetes development workflow – out to the developer community, saying the tool is now generally available after 5,000 commits from nearly 150 contributors to the project. Kubernetes – the de facto container orchestration standard – has become the linchpin of much cloud-native computing, sitting underneath swathes of cloud-based tools to manage how applications run across a wide range computing environments.

  • Molly de Blanc: Rebellion

    We spend a lot of time focusing on the epic side of free software and user freedom: joys come from providing encrypted communication options to journalists and political dissidents; losses are when IoT devices are used to victimize and abuse. I think a lot about the little ways technology interacts with our lives, the threats to or successes for user freedom we encounter in regular situations that anyone can find themselves able to understand: sexting with a secure app, sharing DRM-free piece of media, or having your communications listened to by a “home assistant.” When I was writing a talk about ethics and IoT, I was looking for these small examples of the threats posed by smart doorbells. False arrests and racial profiling, deals with law enforcement to monitor neighborhoods, the digital panopticon — these are big deals. I remembered something I read about kids giving their neighbor a pair of slippers for Christmas. This sort of anonymous gift giving becomes impossible when your front door is constantly being monitored. People laughed when I shared this idea with them — that we’re really losing something by giving up the opportunity to anonymously leave presents. We are also giving up what my roommate calls “benign acts of rebellion.” From one perspective, making it harder for teenagers to sneak out at night is a good thing. Keeping better tabs on your kids and where they are is a safety issue. Being able to monitor what they do on their computer can prevent descent into objectively bad communities and behavior patterns, but it can also prevent someone from participating in the cultural coming of age narratives that help define who we are as a society and give us points of connection across generations.

  • FOSSA Wins CNBC Upstart 100 Award [Ed: FOSSA can be a misleading name. They merely deal with data about FOSS but are themselves not FOSS but proprietary software.]

    FOSSA, the open source management company, today announced that it has been selected for the prestigious Upstart 100 List, CNBC's annual list of 100 top startups to watch. The Upstart 100 is an exclusive collection of companies that are building brands, raising money and creating jobs on their path to becoming tomorrow's household names. CNBC's selection committee chose FOSSA from more than 600 nominees, scored across eight equally weighted quantitative metrics, including scalability, sales growth and workforce diversity.

  • Fugue Fregot is now open sourced to enhance the experience working with the Rego policy language

    Rego is part of the Open Policy Agent (OPA) policy engine, which Fugue adopted this year as its policy as code implementation for cloud security and compliance. Developed as an alternative to Open Policy Agent’s (OPA) built-in interpreter, Fregot provides error handling that is easy to understand and manage with step-by-step debugging.

  • The Relationship Between Open Source Software and Standard Setting

    Standards and open source development are both processes widely adopted in the ICT industry to develop innovative technologies and drive their adoption in the market. Innovators and policy makers assume that a closer collaboration between standards and open source software development would be mutually beneficial. The interaction between the two is however not yet fully understood, especially with regard to how the intellectual property regimes applied by these organisations influence their ability and motivation to cooperate. This study provides a comprehensive analysis of the interaction between standard development organisations (SDOs) and open source software (OSS) communities. The analysis is based on 20 case studies, a survey of stakeholders involved in SDOs and OSS communities, an expert workshop, and a comprehensive review of the literature. In the analysis, we differentiate according to the governance of SDOs and OSS communities, but also considering the involved stakeholders and subject matter. We discuss the preconditions, forms and impacts of collaboration, before we eventually focus on the complementarity of the different Intellectual Property Right (IPR) regimes. Finally, we derive policy recommendations addressing SDOs, OSS communities and policy makers.
