Untangling WebSockets
I have a confession to make. I enjoy reading RFCs. I love the ascii-art technical diagrams, the ruthless exposition of edge-cases, and the frenzied all-caps MUST, REQUIRED, and SHALL.
Let's Make a JavaScript Bundler!
WebPack, Browserify, and the billion other JavaScript bundlers out there are black boxes into which we feed source code. While these existing tools work quickly and correctly, it’s educational to see the challenges that went in to developing them. This blog will lead you through the journey of creating a JavaScript bundler. Along the way you will learn about abstract syntax trees, digraphs, code generation, traversal orders, scoping rules, and function isolation.
CMS.609 Program 0.5
A class I am taking this semester, CMS.609: The Word Made Digital, involves the creation of four to eight computer programs. These programs are intended to explore the intersection of technology with literature. I will write a blog post for each program to discuss my process and artistic intent. This first entry details the creation of Program 0.5. What follows is a story of the wonderful benefits of overdesigning a simple system.
Low-level Optimization in a High-level Language
A year ago I took Performance Engineering Optimization. The first lecture launched into a study of matrix multiplication. Starting with a simple python program, the professor ran through a series of optimization techniques that sped up the program by a factor of 52,479. However, the first step in this process was to switch to C. I began wondering what would happen if we had stayed with Python or another high-level language. I have finally followed through with JavaScript. Read on for a whirlwind tour of low-level optimizations and a few JavaScript-specific tricks.
The First Project
Phones break. Firefox OS phones break too (for now). This breaking usually leaves behind visible trails that reveal what caused the initial break. In physical terms, if something hits your window it will leave cracks that will be different based on whether the object was a golfball or a brick. If you are lucky, you may have a security camera that happened to take pictures of the window-smashing object.
Why Rust is better than C++, a case study
For the past week I have been working on transferring LLVM’s wonderful Kaleidoscope tutorial to Rust as a way to gauge the possibility of finally introducing a proper REPL into the language. I am still working on getting the JIT compiler functioning, but I thought I may as well document some thoughts about where Rust is infinitely superior to C++ and where it still needs some improvement.
Plausible Deniability in JavaScript
Plausible deniability is a wonderful characteristic to have. It would be nice to never have to choose between freedom and Freedom even when under a deluge of subpeonas and warrants. Most developers believe they can never achieve this lofty goal, choosing instead to leave themselves and their users vulnerable and exposed. I believe this is both wrong and unnecessary. To prove my point I created blowfish.js, a simple and secure client-side encryption library. Building on blowfish.js, I developed ByteHaven, an example of zero-knowledge file storage.
