YAMS: Awesome MIPS Server

My EECS 314 project group (Jeff Copeland, Andrew Mason, Thomas Murphy, Katherine Cass, Aaron Neyer, and myself) created a HTTP 1.0 web server, written entirely in MIPS assembly. In addition to serving static pages, it also comes with “dynamic content” courtesy of a Brainf*** interpreter also written in assembly.

PyWall—A Python Firewall

My EECS 444 project group (Jeff Copeland, Andrew Mason, Yigit Kucuk) implemented a firewall in Python. While obviously not practical for normal use, this firewall illustrates the basics of packet filtering (including TCP connection tracking) in a high-level lanugage, which is much easier to understand and extend than C.

Corvid—Static Site Generation Made Easy

For our Software Engineering project, my team (me, Jeff Copeland, and Kyle Deal) created a web application that helps people create simple static web sites. It uses Pelican under the hood, and it’s implemented in Python using the Django web framework. Unfortunately, Corvid is no longer deployed. However, a few friends are working on a sequel for their senior project – stay tuned.

KChat—In-Kernel Chat Server

A kernel module that implements a special device file that allows everyone with a file open to send each other messages in real time, like a chat server. If you think about it, it is acutally an IPC mechanism. Whatever you call it, it’s a lot of fun.

PySwizzle—A Twitter Bot

Hacker’s Society hosted an event called “Python and Pie” for incoming freshmen during Fall 2015 orientation. I gave an intermediate Python tutorial, which was all about writing a Twitter bot using Python. As a result, this bot and the accompanying tutorial are now on GitHub for others to learn from. The bot responds to any @mention with a randomly chosen Taylor Swift lyric.

A Simple Shell in C

I wrote this to illustrate the different system calls and mechanics that underlie one of a programmer’s fundamental tools: the shell. I also wrote a tutorial about it.

Tetris in C!

A 24 hour Tetris implementation written in C, using the ncurses library. I wrote an accompanying blog post about it, which also touched on how important I find my personal projects, even if some are reimplementations.

This library extends the standard C library with dynamic lists, hash tables, regular expressions, command line argument parsing, several string-handling utilities, logging, and lightweight unit testing. It’s an experiment in making an API as well as sharing code. Several of my other C projects depend on it already.

CBot–IRC Bot in C

A fun little challenge - write a functioning IRC bot in C! This little guy was a great excuse to use Libstephen’s regular expressions in the real world, as well as learn all about dynamic loading of modules and the IRC protocol. CBot currently has the basic functions necessary for a chatbot, and I’m sure I’ll return every now and then to expand on his available plugins.

A minesweeper game written entirely in C, with both a command line and graphical interface. This was a fun and short project to apply my C knowledge, as opposed to my more ambitious, long running projects above.
