Language, trees, and geometry in neural networks
Language is made of discrete structures, yet neural networks operate on continuous data: vectors in high-dimensional space. A successful language-processing network must translate this symbolic information into some kind of geometric representation—but in what form? Word embeddings provide two well-known examples…

Writing Hello World in Web Assembly (2017)
Web Assembly is written in an s-expression syntax (wast) and then needs to be translated down to binary encoded wasm. Below is a gist of wast that imports the stdlib.print function taking a memory location offset and a length, as well as importing a block of memory from the controlling runtime. We then store the…

This post is a write-up of a solution to part of a programming puzzle I did yesterday. It’s a little different than the usual “solution + theory” approach, though: I’m going to talk about the actual steps you’d need to take to get to the solution (i.e. what to google, what intermediate code looks like, etc.).
