Why Compute does not yet support JavaScript
Sean Leach
Building our own compiler toolchain allows Compute to be both performant and secure. It also means we have to bring developers’ most-loved language into the fold in the right way.

State at the edge
Peter Bourgon
With the introduction of Compute, Fastly provides a richer model for the CPU. WebAssembly, powered and secured by the Lucet compiler and runtime, unlocks essentially arbitrary code execution within each request lifecycle. This raises the immediate question: what would a richer model for memory, or state, look like?

Why “by developers, for developers” matters
Joshua Bixby
Developer-centricity is now a mission-critical philosophy for companies to embrace. And during COVID-19, we all know that the stakes have never been higher. We’ve seen that businesses that operate with a dev-first mindset at their core will have the strategic advantage and will only increase it, today and into the future.

How Compute is tackling the most frustrating aspects of serverless
MJ Jones
Serverless solutions are good news for developers, but they can cause plenty of headaches, including cold starts, regional latency, and a lack of observability. Compute, Fastly’s serverless compute environment — built on Wasm and run globally — can help solve those problems.

Meet AssemblyScript: your next computing language
Aaron Turner
AssemblyScript is a variant of TypeScript that produces WebAssembly binaries, the binary format that powers Fastly’s Compute@Edge. It’s a new technology supported by all major browsers, and relative to JavaScript, it offers predictable performance, making WebAssembly well suited for computationally intensive tasks. Let’s dig in on why AssemblyScript is your next computing language.

Creating an Efficient Language with Zig | Fastly
Hannah Aubry
Zig is a general purpose programming language, meaning that if you have in front of you something that looks like a Von Neumann-ish, Turing-complete machine, you should be able to comfortably program it with Zig. Lately there has been a lot of interest in two such (virtual) machines: BPF and WebAssembly.

Prevent Wasm Compiler Bugs Early | Fastly
iximeow, Chris Fallin
We recently discovered a compiler bug in part of the WebAssembly compiler that we use for Compute@Edge, that could have allowed a WebAssembly module to access memory outside of its sandboxed heap. But because of the people, processes, and tools we have in place, the bug was caught and patched on our infrastructure before it was exploited.
