Down to the Wire

Zeros and Ones - TypeScript

Matthew Savage

Hey there! I’m Matthew, and for my inaugural post I’m going to start a hopefully-recurring segment called “Zeros and Ones” - essentially, opinions on a given topic broken down into zeros (negatives) and ones (positives). Today’s post will discuss a language I’ve fallen in love with over the past couple of months: Typescript.

If you’re not familiar with TypeScript, it’s a superset of JavaScript that adds the ability to annotate variables with types. It was created by and is maintained by Microsoft, who introduced it in Ocotober 2012.

Context Free Grammars and the Tyranny of Node

Zachary Wade

While language and grammar are undoubtably linguistic constructs, they have very practical uses inside the realm of computer science. However, while looking for language and grammar parsing tools written for Node, I was disappointed to find no easy-to-use and suitably-flexible libraries. In response, I began development on Tyranny, a node module that allows for the description and parsing of arbitrary context-free grammars. Here is what it is, how it works, and what it does.

Stream Based Processing in Node

Zachary Wade

Over the past few weeks, I have begun working on a set of tools called hakkit for helping me to write CTF scripts in node.js. Many of the ideas are lifted off of pwnlib, but soon after I started, I realized that by utilizing Node’s stream APIs, I could take my tools a step further than the pwnlib ones. By behaving similar to unix file descriptors, Node streams allow for powerful and extensible data manipulation.

Welcome to Down to the Wire!

In the coming weeks we will start adding posts and discussing current projects and goals, including an upcoming post about developing Down to the Wire itself. Until then, however, I wanted to share a little bit about what DttW is, and why we decided to start it.
