Thank you for making that available! I understand why it's hard for upstream Rust to provide and I hope they'll find a solution eventually but until then not having to reinvent that wheel saved us a lot of time!

The latter is very achievable using the Relooper algorithm developed by Alon Zakai and described in the Emscripten paper: https://dl.acm.org/doi/10.1145/2048147.2048224

I don't think that's true. It was designed for its purpose by people that knew what they were doing based on experience gathered from implementing previous incremental steps including emscripten's original JavaScript output a

gn is of course a meta-build system, the initials stand for "generate ninja". ninja does the actual build execution. The Firefox build system has a similar homegrown frontend called mozbuild, which generates Makefiles for the actu

It's not really written down anywhere but you can see the gory history of how we got it together in bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=921040 We used the MacOSX SDK from Xcode, packaged up into our

Hi! Post author here, happy to answer any questions. Part 2 of this blog post should be out next week, it'll get into some more specifics of how we're using Rust.

I dunno, personally I enjoy working with Matt and like that he feels this way about us. FWIW I don't really believe it's even possible to rank people based purely on talent. I worked with some incredibly talented engineers in my

Very cool! Tangentially related, I looked into reimplementing `codesign` in Rust while I was at Mozilla. We wanted to see if we could take Apple hardware out of the loop for our release process after we had switched Mac Firefox builds to cr

This mostly matches what I've come to believe over the course of my career with one slight tweak: also make sure that your code can handle the immediate next thing you know needs to be done. Don't try to plan any farther ahead t

We're going off into the weeds here but in C this is implementation defined. In Rust you can use `#[no_std]` and the semantics are all well-defined. There's a thriving Rust embedded ecosystem that's doing just fine. Yes, the

The point isn't that it should be easy to do terrible broken things like this. The point is that you will encounter these things in the real world and have to deal with them in some way. Rust's OsStr[ing] let you do that. If you r

I'm not sure there's a meaningful distinction to be drawn there for the vast majority of usage, to be honest. A language's standard library is generally considered to be part and parcel of the language. Everyone's first

Unfortunately the web platform has failed to provide a sensible way to embed HTML content, so images and videos are how people actually share things. You can take an image and save it to your device and share it to any social media service

The web is a complex platform, so it's definitely not hard to wind up using some feature that performs well in one browser but poorly in another. I don't know that it necessarily reflects badly on any individual browser--software

I watched my kids figure out how to use a variety of Android and iOS devices they had never seen before when they were less than 2 years old, so I would argue that touchscreens are in fact more intuitive to use.

This is not entirely surprising, Rust's async I/O story isn't settled yet. tokio and futures exist, but there's some churn there that means it's a bit difficult to deal with at the moment. An RFC for async/awai

If you've got a specific site that this reproduces on that would be helpful. If you can also provide the model of the monitor you're using and the version of your OS that would help us track it down. Thanks!

Keep in mind that by parallelizing work the browser can finish the work it's doing faster, which means your CPU can spend more time idle, which is better for power consumption.

On the flip side, there's plenty of room for writing lots of shiny new stuff in Rust, which is a pretty unique Mozilla opportunity. :)

The redesigned Firefox for Android was roundly praised as the best Android browser for a while. (It's still very good!) It gained very little market share. Unfortunately it's very hard to compete with defaults these days without p
