<input>on your web page, download the index you’ve specified, and display the best search results immediately to your user, as they type. The precomputed index and WebAssembly frontend module make the entire Stork engine very good, and very fast.
Get started with WebAssembly through this simple hands-on tutorial that assumes only general knowledge in web development. The only tools you’ll need to get a taste of Wasm through runnable code examples are a code editor, any modern browser, and a Docker container with toolchains for C and Rust that comes with the article.
I built a new go Playground that uses Web Assembly to run Go code right in the browser. One of the cool things about this is is that it made it way easier to build a secure server execution environment because the server doesn’t execute anything, it just compiles.
A Rust/WASM port of the Python code from the article “Writing a full-text search engine using Bloom filters”. This can be seen as an alternative to lunr.js and elasticlunr.
The idea is to generate a small, self-contained WASM module from a list of articles on your website and ship it to browsers. tinysearch can be integrated into the build process of generators like Jekyll, Hugo, zola, or Cobalt.

Firefox is mostly written in C and C++. These languages are notoriously difficult to use safely, since any mistake can lead to complete compromise of the program.
The team has thus far had 2 strategies for securing the codebase, breaking code into multiple sandboxed processes with reduced privileges and rewriting code in a safe language like Rust.
today, we’re adding a third approach to our arsenal. RLBox, a new sandboxing technology developed by researchers at the University of California, San Diego, the University of Texas, Austin, and Stanford University, allows us to quickly and efficiently convert existing Firefox components to run inside a WebAssembly sandbox.
This strikes me as a bonkers idea and kinda brilliant.
The core implementation idea behind wasm sandboxing is that you can compile C/C++ into wasm code, and then you can compile that wasm code into native code for the machine your program actually runs on.

When’s the last time you read the ECMAScript spec? Marja Hölttä on the V8 dev blog:

The Lumen Project is an alternative implementation of the Erlang VM, more known as the BEAM. It is designed to work in WebAssembly with the specific goal of bringing Elixir and Erlang to the browser with minimal overhead, tightly compiled rather than porting a full VM. Can it replace JS for some developers?
Results are in for the 2019 State of JS survey. I’ve been digging through charts to see what I can see. Here are 7 insights that jumped off the page to me.
Mozilla, Fastly, Intel, and Red Hat are forming a “Bytecode Alliance”, which is described as:
a new industry partnership coming together to forge WebAssembly’s outside-the-browser future by collaborating on implementing standards and proposing new ones.
We have a vision of a WebAssembly ecosystem that is secure by default, fixing cracks in today’s software foundations. And based on advances rapidly emerging in the WebAssembly community, we believe we can make this vision real.
Security seems to be at the dead center of this alliance. Click through for an in-depth rundown of why this is a problem and what they plan to do about it. Also, some awesome code cartoons from Lin Clark (I assume).
Jerod is joined by Chris and Desmond (co-hosts of the ElixirTalk podcast) to catch up on what’s moving and shaking in the Elixir and Phoenix communities. We discuss what’s attractive about Elixir, what it means to have the language finalized, why folks are so excited by Phoenix LiveView, the ambitious new Lumen project that’s bringing Elixir to WebAssembly, and more.
A look at a new proposal for WebAssembly that will make it possible to easily communicate between WASM and pretty much any language/runtime. This will allow seamlessly embed code from one language into another… think “native modules” except you no longer have to re-compile them on the user’s machine, not to mention you can use them “for free” on the web, and you get sandboxing built in! Wow!
Mat Ryer, Mark Bates, Johnny Boursiquot, and Aaron Schlesinger discuss web development in Go. Go is great at writing server technology, but how good is it for web development? We’ll talk about HTTP, templating, the front-end, Wasm, and we even discuss Buffalo with its creator, Mark Bates.
KBall catches up with Florian Rival about bring a C++ based game engine to the web by compiling to WebAssembly and creating a React-based frontend.
Love that they shared the actual customer-facing results too. As authors Pranav Jha and Senthil Padmanabhan say:
Technology evolves at a very rapid pace. Every day we hear new things getting launched. But only a few make a difference to customers, and WebAssembly is one of them.
WebAssembly is a powerful tool for bringing command line utilities to the web and giving people the chance to tinker with tools.
Yet another excellent use case for Wasm.
We’re talking with Syrus Akbary about WebAssembly and Wasmer — a standalone just in time WebAssembly runtime aiming to be fully compatible with Emscripten, Rust, and Go. We talked about taking WebAssembly beyond the browser, universal binaries, what’s an ABI?, running WebAssembly from any language, and what a world might look like with platform independent universal binaries powered by WebAssembly.

Wasmer is a standalone JIT WebAssembly runtime with an aim to be fully compatible with Emscripten, Rust, and Go. Check the roadmap and tune in to a future episode of The Changelog with Syrus Akbary, the creator of Wasmer.

In a post with a title borrowed from Ariana Grande, Steve Klabnik is announcing his departure from Mozilla and what he hopes could be his next moves.
Mozilla is not interested in hearing what I have to say. And that’s fine, but when I take a step back and think about things, that means it’s time to go, for both my sake and Mozilla’s. So I’ve just put in my two weeks’ notice.
The interesting thing isn’t exactly that he’s moving on from Mozilla, it’s that he’s betting big on WebAssembly.
I’ve also been enamored with another technology recently: WebAssembly. 2019 is going to be a huge year for WebAssembly, even if many people don’t know it yet, and may not see the effects until 2020.
So what’s his next move? Something different…
In terms of the actual work I would like to do, I don’t think a traditional engineering role really suits me. Don’t get me wrong, I love to write some code, but I don’t think that those kinds of roles really play to my unique strengths. What I really love to do is teaching, evangelizing, and growing something.
We’re tracking the activity around Wasm quite well, but we’re open to more suggestions if you have them. In this post Divya shares some insights and the big idea behind Wasm.
It is undeniable at this point that WebAssembly is (and will be) a huge game changer for web development. As a lower level language, it efficiently handles more computationally heavy tasks and allows us to so more, with less. Though we’re still in the early stages of WASM, the future looks bright.
How do MIDIs even work? Why won’t they play on the web anymore? Can WASM save the day (hint: yes)? How does Feross get so many eyeballs on his creations? Is Preact awesome for building sites like this? What’s the future of BitMidi look like? Don’t ask us, listen to the episode!
Very cool! I tried to get to a Command Prompt, but it seems key input has been disabled.
There’s lots of fun comments in this Twitter thread.
A lot of people wanted Steve Klabnik to elaborate on this from a recent post on WebAssembly…
Some have compared WebAssembly to Java applets; in some ways, they’re very right, but in some ways, they’re very wrong. Eventually I’ll write a post about the wrong, but for now, the right: in some sense, WebAssembly is a different way of accomplishing what the JVM set out to do: it’s a common virtual machine that can be used to build very cross-platform software.
Here’s a great take away if all you want is a tldr…
