Qt3D, QtOpenCL Spark New Interest

Filed under
Development

Qt3D is the Qt component that adds 3D support to Qt Quick for easily integrating 3D functionality. Qt3D has been in development for some time and was going to be an "essential" module to Qt 5.0 before being moved to just an add-on as part of Nokia's Qt changes prior to selling it to Digia. Qt3D offers up a lot of potential for 3D user-interfaces and applications, but hasn't seen too much work recently -- the last time we got to mention it was when talking about OpenGL taking on a greater role within Qt in late 2012.

Fedora 21 Will Likely Make Java 8 The Default Runtime

Filed under
Development
Red Hat

Proposed last week was the feature of Java 8 for Fedora 21. This feature comes down to packaging up and shipping java-1.8.0-openjdk in Fedora 21. Part of this feature that's making it contentious among Fedora stakeholders is that OpenJDK/Java 7 will be obsoleted and removed.

Introducing rr ( Firefox Development)

Filed under
Development
Moz/FF

Many, many people have noticed that if we had a way to reliably record program execution and replay it later, with the ability to debug the replay, we could largely tame the nondeterminism problem. This would also allow us to deliberately introduce nondeterminism so tests can explore more of the possible execution space, without impacting debuggability. Many record and replay systems have been built in pursuit of this vision. (I built one myself.) For various reasons these systems have not seen wide adoption. So, a few years ago we at Mozilla started a project to create a new record-and-replay tool that would overcome the obstacles blocking adoption. We call this tool rr.

  • 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.

  • 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.

  • [Older] Linux Systems Performance

    Systems performance is an effective discipline for performance analysis and tuning, and can help you find performance wins for your applications and the kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. This talk summarizes the topic for everyone, touring six important areas of Linux systems performance: observability tools, methodologies, benchmarking, profiling, tracing, and tuning. Included are recipes for Linux performance analysis and tuning (using vmstat, mpstat, iostat, etc), overviews of complex areas including profiling (perf_events) and tracing (Ftrace, bcc/BPF, and bpftrace/BPF), and much advice about what is and isn't important to learn. This talk is aimed at everyone: developers, operations, sysadmins, etc, and in any environment running Linux, bare metal or the cloud.

  • Basic Data Types in Python 3: Booleans

    Welcome back to our ongoing series of blog posts on basic data types in Python 3! Last time, we explored the functionality of strings. Today, we dive in to another key data type - booleans. Booleans (and "boolean logic") are an important concept in programming, representing the concept of "true" and "false". If you're learning Python, you might also want to check out TwilioQuest 3. You'll learn about basic data types like the boolean, and much more about Python programming. Ready to learn how to use booleans in Python 3? Let's get started!
