oars

A rust library for orthogonal array generation and verification. It contains constructors for orthogonal arrays as well as functions that can verify whether a given point set is a valid (strong) orthogonal array. Development is currently in progress, as we are currently working on efficiently generating strong orthogonal arrays. The library is available at crates.io.

pcg-rs

A port of the PCG random number generation library, written in pure Rust.

nib

A WIP renderer written in Rust.

ensh

Ensh stands for “Enayet Shell.” It is a basic shell written in Rust, designed to be modern and efficient. It is currently a stable viable shell for MacOS and Linux. It uses Travis CI for testing and the Cargo package manager to manage unit tests. At the time of writing (can’t always promise I’ll update this page as soon as I update the project), the ensh binary size is only 160K, which I’m working on paring down.

I originally started this project to learn Rust, and learn Rust as a systems programming language. This project also taught me about process management in Unix and a lot about maintaining and deploying a product.

cttp

A multithreaded HTTP 1.1 server written in C. I wrote this to get a better handle on BSD sockets and because I haven’t really written any code that deals with networking. The server can handle a decent number of mime types, and functions as a fairly basic HTTP server. It can receive GET requests to a particular path, and will serve the file from that path to a browser. The server is also multithreaded (using POSIX threads) and can accept multiple connections at once.

cttp uses the pthreads library and cmocka to manage unit testing. Travis CI is used for deployment and testing.

afnan.io

A personal website/blog powered by Jekyll and Travis CI. Pushing to Github triggers a build from Travis, which ensures that the website builds properly. You’re looking at it right now!

Matasano Cryptopals Challenge

I am working on the Matasano Cryptopals Challenge, a set of challenges designed to teach some of the basics of cryptography. The challenges can be found here.

tiny search engine (TSE)

For a software development class, we created a small search engine in C. It downloads the contents of a webpage, indexes it, and ranks the results of a boolean query and displays it to the user. It follows the Unix development philosophy. At the instruction of our professor and Dartmouth College, the source code cannot be made public, but I can provide the source code upon inquiry. Email me if you want to see the source.

MyRuns

A fitness/run tracker app created for a computer science class at Dartmouth College. Encourages good development practices, modularity, and MVC. Uses a variety of Google/Android services like location, accelerometer, and is multithreaded. Also uses machine learning to infer the type of activity a user is carrying out.
