Emacs Config

Most serious users of Emacs end up with a non-trivial configuration. This configuration is actually a software project and should be treated as such. This means that a good Emacs config uses modularisation, clean code, comments and source control.

My Emacs configuration is my attempt at doing these things well. It uses the wonderful straight.el and use-package for package management and configuration. I've even written an article about use-package.


elemental is an Emacs extension that provides elisp functions for "intelligently jumping between and transposing list/tuple/dictionary/function-parameter elements". It's hosted on GitHub:

I don't actually use this any more because I use Evil and discovered that evil-args and evil-exchange can do what elemental can do and more. It's still a decent example of how to deal with some arcane corners of elisp developement (syntax tables) and writing unit tests in elisp.

Raspberry Pi VU Meter

My wife and I once worked on a Raspberry Pi based media server with a built-in analog VU meter. There's some articles about this project on the blog whic includes descriptions of the software and electronics we created.

See to skip the articles and get straight to the code.


This is a fairly rough extension to Thunderbird that provides Mutt-like key bindings and functionality.

It is heavily used by the author every day but could do with some cleaning up, documentation etc. If you're interested in using it yourself, please email

Various PyBlosxom Plugins

A long time ago this site used to be powered by PyBlosxom. I ended up creating a few plugins for it which are recorded here for posterity.


This plugin allows the rst (reStructured Text) and readmore plugins to work together. It defines a reST "break" directive which will trigger the readmore plugin's breakpoint functionality. See the documentation at the top of the file for more information.

This simple plugin allows you to define a directory under your datadir that contains draft blog entries. Draft entries will not be displayed on the blog by default. To display drafts add a 'drafts' query parameter to the end of the page URL (for example or

spamquestion is a simple PyBlosxom plugin that helps to prevent comment spam.

A randomly selected question is shown on the comment form for a blog entry. The user must answer the question correctly in order to submit a comment. The approach works because each blog will use it's own set of unique questions that are easy for a human to deal with but are virtually impossible for a computer to answer unaided. This prevents makes automated spambots ineffective.

Unlike CAPTCHA based anti-spam systems, this approach does not disadvantage visually impaired users and works even in text only browsers.

ssh-agent-applet is a Gnome applet that allows you to conveniently keep your ssh key(s) on external media. This means that if your computer is cracked or stolen, the attacker will not have a copy of private ssh key(s).

Using ssh-agent-applet, your keys are loaded into ssh-agent as soon as you insert your "key drive" into a USB port. The drive is automatically unmounted once the key loaded so you can remove it from the USB port immediately.

For developers, ssh-agent-applet is an example of how to write Gnome applets in Python and how to interface with HAL from Python using DBUS.
