General:

Am respected member of the Linux Opensource community

Named in Linux Magazine's (http://www.linux-mag.com) Who's Who Top 50 Developers to watch August 1999 issue.

Have managed large scale open source projects with developers spread across the world.

Know C backwards and regularly write API layers for application development in C.

Interests:

GUI:

I am very interested in improving the standards of Graphical User Interfaces, most especially on the UNIX platform, that has a powerful core, but lacks any decent interface to it. In this quest I have modified the code for RXVT to support pixmap backgrounds. This has now become the standard terminal emulator for many UNIX users. This project is now being carried on under the new name of Eterm, and a new group of developers. This sparked much of the theme development under UNIX/W-Windows.

As a continuation of this I have released Development Versions of Enlightenment (http://www.enlightenment.org/) , a Window Manager for X-Windows that re-defines the way Window Management is defined. I have written this Window Manager from the ground up, not basing it like traditionally has been done, on TWM or FVWM. In order to aid me in this goal I also wrote Imlib and now Imlib2, a shared library distributed with Enlightenment that handles image loading, scaling and rendering to any bit depth and palette as fast as possible.

Graphics:

I have written many programs directly and indirectly for my employers. Amongst these some are: Imlib2 (second generation image loading, saving, rendering and manipulation library which is faster than any of its competition and easy to use), Evas (hardware accelerated canvas abstraction on an object level with OpenGL back ends for display rendering, software accelerated MMX back ends (Imlib2), plain windowing system rendering and more), Edb (database abstraction library for data and configuration loading, saving and management with optimisations), EFM (graphical file manager - similar to Mac Finder but with much nicer graphics and more power), Enlightenment, Eterm, Ebits (macro image composition and geometry constraint engine library), Etcher (GUI tool to edit Ebits files), Ecore (event abstraction layer library with time-out wrappers and convenience layers to speed up development), Electric Eyes (image viewer), patches in X-Windows X-Server, Theme system for Widget Set (GTK+), Animation codec's and players (Eanim - never released), Network Audio mixing daemon (Esound - started from sounD) and more. Have written real-time 3D graphics engines (triangle-based, texture-mapped, with lighting) to run on low-level systems at high speed. Have dealt with most things graphical at some point, some in more detail than others.

Networking & Administration:

I administer several machine as simply a part of software development and ensure they all run smoothly and can synchronise their settings and other information over a WAN. I write many shell scripts & C programs to help with this - as well as know how to configure all the services on my systems (dhcp, dns, apache, users etc.)

Other:

I speak German fluently, and learn French also. I have both German and Australian citizenships. I enjoy speaking and learning foreign languages, as well as travel, and novel experiences. Have learnt Japanese too but am at basic conversation level.

General Experience:

I have been heavily using UNIX (Solaris, ULTRIX, IRIX and Linux) since early 1994 in capacities from a user to an administrator to developer. I have become familiar with most UNIX tools and facilities, and have used them to their fullest. Before 1994 I did hardware level programming for other systems (Amiga). I have set up several networks, administered them, and developed many applications, primarily for X-Windows. I am intimately familiar with X, Xlib and related topics, am highly proficient in C and almost any areas concerning graphics. I have been programming in various languages for over 17 years.

Have given numerous speeches about X-Windows, and the Enlightenment project at both NOVALUG in Northern Virginia and ALS (Atlanta Linux Showcase). Have spoken at LinuxWorld, San Jose twice, Linuxworld New York twice, The Bazaar, New York, NYSSA speech, New York, IT2000, Sydney, CALU Melbourne, CALU Sydney, Cal Poly University California, Santa Cruz LUG speech, LinuxTag, Stuttgart, UK Linux Developers conference London, Ottawa Linux Symposium Speech, and many others.

Projects worked on:

Enlightenment

A UNIX window manager for X-Windows. Am lead programmer, designer, team leader, author and still run this project in my spare time. A team of about 10-15 people work on this, distributed across the world. This program is written in C and consists of over 100,000 lines of original code. Development continues and the new code base is about 200,000 lines of new code.

Evas

A 2D drawing canvas library. Written in C. Handles graphics display on a higher level object basis. Does anti-aliasing and alpha blending image compositing. Highly optimised for display. Has several rendering back ends written for it (output to display, to memory, to disk, via OpenGL). Am lead developer and designer.

Imlib2

Image loading, saving, and manipulation library. It can composite images, scale and rotate them, apply filters, has a loadable modular loader/saver architecture. Written in C and x86 assembly. Handles anti-aliased truetype font rendering too. Also renders anti-aliased lines, polygons and other primitives. Can load multiple image formats and save them out too. Am lead developer and designer.

Imlib

Graphics loading, caching, rendering library designed to work with X11 generating high quality graphics quickly from source image files or data. Written in C.

Edb

Berkley database abstraction library that wraps and encapsulates these database files and makes accessing them on multiple architectures and platforms a breeze with 0 code changes. I also optimises access by caching database connections. Am lead developer and designer. Written in C.

Ecore

X11 event, file descriptor, Sys V IPC and UNIX signal abstraction and event engine library that unifies all these into 1 neat event loop. It also optimises X11 access by avoiding round trips to the server and caching state locally. Am lead developer and designer. Written in C.

Eet

A compact data encoding/decoding library as well as saving and loading engine. Very small and fast. Written in C.

Emotion

A video object library written in C allowing media streams (MPEG1/2, AVI, WMV etc. etc.) to become part of a canvas and be scaled, alpha blended on top of each other to allow of dynamic user interfaces using videos either as components or subject matter in multiple places at multiple sizes etc.

Epeg

A small extremely fast JPEG thumbailer library, that can thumbnail dozens of JPEG's per second bu taking shortcuts in the loading and thus scaling process. Allows application programmers to use it very simply to generate JPEG thumbnails. Written in C

Edje

A complex theme library written in C that virtualises and abstracts GUI layout and visual appearance from the programmer, allowing the artist to define animation, event reaction, look, feel, spacing, layout and much more. Allows for scripting (based on Embryo), simply event reaction, tweening and more. Includes compiler and de-compiler to generate compact theme files.

Embryo

This is a complete virtual machine and compiler written in C (much like the Java JVM or C#/.NET virtual machine and compiler) based on the Small language implementation. This is a small shared library that is designed to be extremely small and compact as well as portable. The VM runs about double the speed of Java's JVM.

VACM

Cluster management software & system, Wrote user interface and works on client-side libraries and modular code-base. Helped with design phase of version 3.0 before project was put on hold. Member of 5 person tam working on it at VA Linux. Written in C.

Tex
