#### OPEN SOURCE / COMMUNITY PROJECTS:

__wmstickynotes__  
__Volunteer C programmer__  
(2014)  

Contributed "--nowrite" flag to optionally prevent sensitive data from being
stored in the filesystem. [Project homepage](http://wmstickynotes.sourceforge.net)

__ZMap project (University of Michigan)__  
__Volunteer C programmer__  
(2013 - present)  

Ported zmap multithreaded network scanner from Linux/gcc to FreeBSD/clang.
Replaced Linux raw sockets interface with more portable pcap API and packet
crafting. Implemented portable protocol header structs using C99 stdint types
to replace Linux-specific system structs. 
[Port repository](https://github.com/coydog/zmap-freebsd)

__Gentoo Foundation__  
__Volunteer C programmer__  
(2012 - present)  

Submitted patches for legacy X11 system load monitor applications wmmon,
wmfire, and wmtop. Fixed bugs including data type issues on 64-bit
architectures with greater system resources than were possible on original i386
platform. Fixed statistics reporting issues caused by changes in the Linux
procfs API. Tracked revisions with git and submitted patches to upstream
maintainers.
*Not an offical Gentoo developer.* Resolved the following tickets: 
	[404323](https://bugs.gentoo.org/show_bug.cgi?id=404323)
	[407325](https://bugs.gentoo.org/show_bug.cgi?id=407325)

#### Independent projects
(1999 - present)

* Conducted research into HTTP server slot denial of service attacks.
  Implemented multithreaded malicious HTTP clients in Rust and C to test
  mitigation techniques.
* Developed audiosniff, a network monitor in C that represents network traffic
  as audio tones to aid network troubleshooting and development. Audiosniff
  intercepts traffic using pcap and outputs tones with the speaker driver of
  FreeBSD, NetBSD, or OpenBSD. Ported audiosniff to Linux by implementing a DSP
  sine wave tone generator using the portaudio library.
  [Repository](https://github.com/coydog/audiosniff)
* Developed fouriergen, a simple DSP synthesizer capable of harmonies, to
  enable music composition using shell scripting.
  [Repository](https://github.com/coydog/fouriergen)
* Wrote breaknode.py, a Python script to test Node.js HTTP servers for
  vulnerability to the request pipelining denial of service attack in versions
  prior to October 2013.
* Updated legacy ypsnarf security auditing tool for NIS+, for compatibility
  with modern Solaris derivatives. Ported the tool to Linux.
  [Repository](https://github.com/coydog/ypsnarf-2013)
* Developed utilities using C and Bash shell scripting for drive imaging and
  backups on Linux, BSD, and Mac OS X. Utilities wipe free space, image the
  storage device using dd, and compress with gzip or bzip2, using a
  cryptographic hash for integrity checking. 
* Conducted research into improving performance of consumer-market routers by
  offloading DHCP and DNS services onto NetBSD-current/evbarm on RaspberryPi.
* Implemented MP3 player with web browser interface for home stereo system,
  using FreeBSD 3.4, Perl CGI scripts, Apache, and MySQL on a headless PC.
