Lee Goddard .net — another boring personal homepage

Homepages are boring ...

...but as my work has been programming internet applications since 1999, it would be hard to survive without one.

I work remotely or in the UK, and live in Gödöllő, Hungary, with my wife Paula (who made this background image), my children, eight-year old Ilona (in this photograph) and four-year old Jacob.

Anyway, this my homepage and not my CV, and as such here I define myself by more than my work — nothing is more boring than a computer programmer who only programs computers, and nothing is less effective in programming computers.

Interests outside of work include Zen, flamenco, modern jazz, Gong, Hillage, Hawkwind, Cézanne, Klee, Kandinsky, Japanese gardens, mountains, forests, lakes, mushrooms, wild grasses, and Indian food.

Generative Sound With L-Systems

Lindenmayer tree,
A → AB, B → A.

Computer-generated music has been an interest of mine since dissing it whilst at university in 1999, where I took a course called AI a and Creativity with the lovely and inspiring Maggie Boden OBE. However, despite the clever psuedo-music and clichés of Garage Band and Baysian networks, I find the attempt at human-sounding music to be depressingly emotionless, their lack of lyrics and lyricism removing them far even from the song machines of Orwell's 1984.

But I have always been fascinated by the idea (shared by Kandinsky, Klee, Victor Pasmore to name three of my faviourites) that paintings and images could be rendered as music, so when I cam across the extremely simple Lindenmayer System, the music application was obvious and irresistible, and the first prototype created within a day.

The appeal of the equation, generally used to model plant growth, is its simplicity, as this rough graphing demo illustrates. Without simulating varying soil, light, and weather conditions, growth is unnaturally regular, but the instantly familiar shapes produced by equations of as few as four bits encourages me to think Lindenmayer and co were closer to discovering some secrets of creation than anyone. But that's another subject.

As for the 'musical' output, it depends on your taste, and how you imagine a plant might sound. To my ear, it is often reminiscent of Terry Riley's dervish music, and thus the to Acton's own The Who's tribute to Terry Riley (and Avatar Meher Baba), and thus Talking Heads' Once In A Lifetime.

The two above sounds combined:

My current system is a mixture of HTML5, MooTools (for ease of OO), with the binary midi files being encoded by old-fashioned Perl with Moose (using MIDI-Perl kindly dontated to the world by Sean M Burke). The resluting MIDI file is the imported into Logic Pro, and mastered through a Yamaha 01X and a variety of synths and samplers. However, my work has been moving towards landscapes of Lsystem 'plants,' which would push my current paradigm to the limit, so a rewrite in Java is planned for next year. This would also allow live alteration of a loop, which could be interesting for performance.

Zen and the art of ....

Some of my work

All the work on these sites is mine, apart from the BBC Wildlife site, where I did everything apart from the graphic design and PHP. Most of my work tends to involve GUI but hides behind authentication or on intranets.

Currently...

I am looking for three- to twleve-month contract, anywhere a British citizen can work — I frequently work in my native London (freeloading on my kind family), but would welcome the change to work anywhere else at all. I am happy to work with Perl in any form, or Java (though I have yet to take a Sun/Oracle certification), but I am especially interested in HTML5 and advanced OO JavaScript, preferably using Angular, any MVC/P framework like Backbone, with or without jQuery/MooTools/Underscore, and real-time work with HTML5 audio, Web Audio API, SVG and canvas manipulation. My ideal role would be making use of Node.js — I've lots of non-commercial experience, but am still finding few contract opportunities that make use of such interesting tech, let alone in an Agile environment with dev/CI/stage VMs managed through Jira.

In the past year or so, I have been focusing my free time on using and improving the Node/HTML5 L-systems audio, described above. Personal projects include Freedharma (Backbone), an SPWA to create video subtitle files in real-time (Angular), Plonk, a (Web Sockets/Audio) rip-off of Plink, a collaborative music doodling tool, a bit like the silly brush toy which you can see in the Zen section above. From the server's point of view, it's just a chat server, for the client is a kind of musical etchasketch. It does demonstrate the power of WebSockets and weaknesses of the HTML5 canvas element. Perhaps I'll write an article. I'd let you see it, but what ISP supports WebSockets?

When Mozilla eventually completely fixe their HTML5 audio looping bug, I hope to continue development of a simple HTML5 multitrack that allows the mixing and looping, cutting and pasting, of SoundCloud and other online audio files, in the style of Logic/Cubase.

Home-life: Angular Mixer

A coupe of years ago, whilst working away from home, I started writing a sound mixer in MooTools. All went went, until I hit looping bug in Firefox and then my l-system project caught my eye again… Now I’m looking for something to work on with Angular, shortly after being handed a bunch of mp3 […]

JavaScript, Work: Prototype, Trains, Marketing

I was asked the other day if I’d ever used Prototype.js, and I completely forgot that I had used it in Train Game — the library is such a natural extension to JavaScript that its use did not stick in my mind. Although, having now looked again, I do wonder what it is doing with my […]

Home-life, JavaScript, Work: JavaScript Poster Text

Cards - 2013-10-22_14.46.35

A year or so ago, I wrote some client-side JavaScript to allow allow input text to flow around images — it worked perfectly, and was optimized through a server-side process that produced a mask map from the image, which could be sent as JSON with the choice of image being mapped. Whilst optimised, it was […]

JavaScript, Work: My First Facebook Applicaiton

(JPEG Image, 519 × 519 pixels)

This Timeline Word Cloud is my first Facebook application, written in about 16 hours — most of which were spent dealing with horrendous problems within the Facebook JavaScript SDK. On the whole, it is a pleasant SDK, with clear documentation and plenty of Stack Overflow examples (some ugly, some neat). What did bugged me was […]
