Released Code

Perscon

Personal Containers are an experiment in enabling you to collate and control your digital footprint. At the moment the focus is on collecting and managing your own data; future goals include developing ways to enable others to interact with your data for mutual benefit, while still retaining ultimate control yourself. The code is available under the GPLv2.

Homework

This is an experiment using Open vSwitch and NoX to control a wireless Linux access point as part of the wider Homework project. The repository contains snapshots of both Open vSwitch and NoX (as git submodules no less), as well as the Homework specific control script which currently provides basic PERMIT/DENY functionality based on MAC address and exposed via a simple web services interface.

PyRT

I developed the Python Routeing Toolkit while at Sprint ATL, who released it under the GPLv2. It comprises code for collecting and analysing routeing data. This package currently collects BGPv4 and ISIS, and dumps and parses MRTD files including MRTD TABLE_DUMP files (as available from, e.g., RouteViews and RIPE/RIS). A number of utilities for manipulating these dumps are also provided. Since the code on Sprint’s website appears to be orphaned, I have created a github repository here for it.

Karaka

Developed at Vipadia Limited, this is a scalable software system implementing a distributed Skype-XMPP gateway released under the GPLv2. Copyright was acquired by Voxeo Corp. in January 2010.
