In November, I wrote about my team’s work on experimental new web design tools and introduced a survey to rank the challenges of web design and development. The insights you shared continue to inform priorities for the Firefox DevTools' 2019 roadmap. Our main takeaway: developers and designers of every experience level want a better understanding of CSS debugging. We're on it.
Multithreading allows programs to do more faster, but adds synchronization bugs and attacks. Programming languages have evolved different concurrency strategies to help developers manage both the performance and security challenges of multi-threaded applications. Diane Hosfelt explores the challenges of thread safety, and the approach that Rust takes.
Building a virtual reality experience may seem daunting, but it really isn’t. WebVR and frameworks like A-Frame make it easy to get started right. This is why we worked with Glitch to create a WebVR starter kit. Today we introduce a free, 5-part video course with interactive code examples that will teach you the fundamentals of WebVR using A-Frame.
Unsolicited volume can be a great source of distraction and frustration for users of the web. So we are making changes to how Firefox handles playing media with sound and we want to make sure web developers are aware of this new audio autoplay blocking default. With the release of Firefox 66, now in Firefox Beta/Developer Edition, the browser will block audible audio and video, and will allow a site to play audio or video aloud via the
HTMLMediaElement API only once the user has initiated the audio.
With the release of Things Gateway 0.7, Mozilla's IoT team announces experimental support for IP cameras, along with support for a wider range of sensors that track temperature, leaks, and more. Ben Francis also shares plans for evolving the Things Gateway application in 2019, and exploring the value a trusted personal agent could provide to your whole home network.
Memory safety violations leave programs vulnerable to security threats like unintentional data leakage and remote code execution. There are ways to ensure memory safety, including smart pointers and garbage collection. Research engineer Diane Hosfelt explains how Rust’s ownership system achieves memory safety while minimizing performance costs.
