Programming

Final Year Project

The current vogue for social networking software is being matched by an increase in academic interest. My final year project surveys this area, seeking to demonstrate that such systems are workable and can be implemented without raising unresolvable privacy concerns.

Computer technology can transform the way we think about and act on trust.

To this end a small peer-to-peer application, entitled Hearsay, is developed as a proof of concept. The aim is to provide a guide to the creation of a number of interoperable implementations on the XMPP transport layer.

Zopa Listings went live this week

Zopa Listings

We finally went live with listings this week. (See my listing.) Listing is a completely new approach at Zopa. You can select who you lend money to individually. There's still credit scoring (we discard the 'bad ones', but it's a guide rather than a rule.

Borrowers are uniquely identified by pseudonyms. Which means they can choose to promote or associate themselves with their listing. You could place your listing's URL on your blog (like me), or email it to friends & associates.

A Few Interesting Things In Building This Site

Spam

My email address is hidden from spammers without being obscuficated. I just used an image of it. (The ALT text spells my e-mail address out phonetically for accessibility.)

Robots

I've written and used a robots.txt file for the first time, so it'll be interesting to see if this stops robots from chasing down links to PDFs, etc.

Webservices Actually Work Now

I have an entire book section driven by the Amazon REST APIs (What is REST?) , so I think it's fair to say that this stuff really does work now.

My Toy Black-Litterman Optimiser

As a self-education exercise I wrote myself a crude Black-Litterman portfolio planner following the algorithms given on Willian Sharpe's site.

Derivatives == Formal Language ?

Interesting paper from MS Research tries to represent financial derivatives as a small programming language.

Seems to be a great deal more sensible than you might think, since it allows derivatives to be added or subtacted from one another. You could then take all you liablities and net them off against each other... (Counterparty risk and random happenings aside.)

Concurrency Coursework

This coursework received a 100% mark. It is a multi-threaded Eratosthenes filter written in Java, which can be shown not to deadlock.

Software Engineering Group Project

The Living Proof Timetable Information System (LPTIS) was a group project with five people. We built a system for displaying and searching timetables. I was responsible for the overall architecture, and the technical documentation.

Below are this the technical documentation, architecture diagrams (E/R + UML), sourcecode and executable jar file for this project.

LPTIS uses a model-2 MCV architecture, with the domain model having no dependencies on the GUI.
