GitHub - WebAssembly/design: WebAssembly Design Documents
WebAssembly or wasm is a new, portable, size- and load-time-efficient format suitable for compilation to the web. WebAssembly is currently being designed as an open standard by a W3C Community Group that includes representatives from all major browsers. Expect the contents of this repository to be in flux: everything is still under discussion. WebAssembly is efficient and fast: Wasm bytecode is de

lawk - an awk compiler for the llvm
Introduction lawk is a jit compiler for awk that targets the llvm (http://www.llvm.org). It was born as a way of experimenting with the llvm infrastructure in a setup more complex than the tutorials. As such, its main purpose is didactic and I do not forsee it becoming a real alternative to the already available implementations of awk. Its foundation lies in GNU awk.

JavaScript in JavaScript (js.js): Sandboxing Third-Party Scripts | Princeton SNS Group
Early last fall, I started working on a project called js.js with two other graduate students, Naga Katta and Stephen Beard. We started using a public Github repository from the start, and at the beginning of January, the author of three.js found and tweeted a link to our repository to his many followers. Soon after, a post wound up on Hacker News. Unfortunately, we weren’t very far along in the p
