November 2019 was a busy month for the Mozilla Developer Roadshow, with stops in five Asian cities —Tokyo, Seoul, Taipei, Singapore, and Bangkok. Today, we’re releasing a playlist of the talks presented in Asia, with subtitles available for all these talks in languages spoken in the countries on this tour: Japanese, Korean, Chinese, Thai, as well as English. We covered CSS Subgrid, Mixed Reality, Web Compatibility, and more.
A behind-the-scenes look at the evolution of the Picture-in-Picture player for the Firefox Desktop browser. This feature is now available for MacOS, Linux and Windows users. From the beginning, it's been shaped by your feedback and inputs, with user agency as a core principle of our design and development.
The first annual MDN Developer Needs Assessment aims to represent the voices of developers and designers working on the web. We've analyzed the data provided by more than 28,000 completed surveys, and we've identified 28 discrete needs, sorted into 14 different themes. Four of the top ten needs relate to browser compatibility, our #1 theme. Documentation, Testing, Debugging, and Frameworks round out the top five.
Mozilla Hacks covered plenty of interesting territory in 2019. Our most popular posts introduced experiments and special projects, and described the evolution of groundbreaking platform technologies like WebAssembly and WASI. Mozilla WebThings continued to engage attention and adoption. And interest in Firefox releases and Firefox DevTools was stronger than ever. Read on.
Have you ever wanted to know where properties on objects are read or set in your code, without having to manually add breakpoints or log statements? Watchpoints are a type of breakpoint that provide an answer to that question. They are new in the updated Debugger, available now in the Firefox 72 Developer Edition release.
The Machine Learning team at Mozilla continues work on DeepSpeech, an automatic speech recognition (ASR) engine which aims to make speech recognition technology and trained models openly available to developers. In this overview of recent improvements, we'll show how DeepSpeech can transform your applications by enabling client-side, low-latency, and privacy-preserving speech recognition capabilities. Find out how you can participate.
Wasmtime, the WebAssembly runtime from the Bytecode Alliance, recently added an early preview of an API for .NET Core, Microsoft’s free, open-source, and cross-platform application runtime. This API enables developers to programmatically load and execute WebAssembly code directly from .NET programs. Although .NET Core is already a cross-platform runtime, there are good reasons for .NET developers to take a closer look at WebAssembly, as Peter Huene demonstrates in this post.
Please welcome Firefox 71 to the stage! This time around, we have a plethora of new developer tools features including the web socket message inspector, console multi-line editor mode, log on events, and network panel full text search! And as if that wasn’t enough, there are important new web platform features available, like CSS subgrid, column-span, Promise.allSettled, and the Media Session API.
Multi-value is a proposed extension to core WebAssembly that enables functions to return many values, among other things. It is also a prerequisite for Wasm interface types. Nick Fitzgerald has been adding multi-value support all over the place recently, started with the Rust and WebAssembly toolchain. Next he added support to the Wasmtime runtime, and the Cranelift code generator it’s built on top of. Here's his account of the journey.
Firefox 71, now available in Developer Edition and Beta, is an exciting release for fans of CSS Layout. Recently, we covered the arrival of subgrid in Firefox, but there is another property that we've also been keeping an eye on. Firefox 71 implements column-span from Multiple-column Layout. In this post Rachel Andrew describes the progress of the Multiple-column Layout specification.
