This website is based on [jekyll][] (a static site generator). I store the text files for jekyll in a git repository. Here is how I setup automatic deployment of this website. Whilst a lot of this post is generally applicable, some of it (specifically the installation section) is only of relevance if, like me, you are hosted on a [Joyent][] Shared Accelerator.

Before we get started, just note that the git repository storing my website is a bare one in ~/git/design/andrewho.co.uk.git. I'll assume you're happy creating such

For a long time I've used vim as my editor for both composing messages in mutt and commit messages for git. I do this with the following line in my ~/.muttrc (and a similar one in my ~/.gitconfig:

set editor = "vim -c 'set wrap tw=76 fo=toqwal12 nonumber spell' +1"

Recently I refactored my vim configuration files using Tim Pope's excellent [pathogen][1] script. Doing so required me to place the following lines in my

I use a static site generator, specifically [jekyll][], to transform some templates into a set of static *.html files. However, I like to keep the URLs looking clean, and not display the .html extension both because I think it looks better and also so that the URLs purely reflect the content and not the underlying files or CMS used to serve that content. In short, whilst the file being served might be $DOCUMENT_ROOT/weblog/title.html, the canonical URL for that resource should be /weblog/title. Here's how I do that in .htaccess.

The ability in GNU screen to vertically split a display so that two windows are visible side-by-side (which is what GNU screen means by "vertical split") is not available in the latest stable release (4.0.3). It is, however, available in the latest HEAD slated for screen 4.1. Various distributions such as debian have merged the upstream changes into their stable versions; Mac OS X (10.7) is not one of them. Here's how to compile it in.

First, clone the latest HEAD (450e8f38 at the moment):

This post is an update to "[Deploying jekyll (on a Joyent Shared Accelerator)][old-article]".

This website is based on [jekyll][], a static site generator. I host the files for this in a bare git repository on a [TextDrive][] shared server. Here is the procedure I use to automatically deploy the site whenever I push to master. The paths used below will obviously be specific to where I have placed things. I use a bare git repository in ~/git/andrewho.co.uk.git and deploy to

This guide shows how to install debian so that it can be booted and run from a USB drive on a MacBook Air. I use this to store a copy of my PGP master keypair. Networking is deliberately not configured and all operations requiring the master keypair (such as signing other people's keys) are done only on this system. See the debian wiki for information on how to separate your key. Note that this is slightly different to using a live CD. It is not possible to tailor the base configuration of a live CD to one's own requirements, and they frequently automatically connect to the nearest local network. Nevertheless, if you wish to use a live CD instead, I recommend Tails. Arturo Filastò has written a similar guide for Tails.

The method I use requires [VirtualBox][4], which should also contain a working debian installation itself. An alternative method would be to use [debootstrap][5] b

First, install the necesssary packages:

% apt-get install libpam-oath oathtool

Generate a key and write it to /etc/users.oath (NB the key will be in hexadecimal; if you are using Authy you will want to convert it to BASE32):

% KEY=$( head -c 1024 /dev/urandom | openssl sha1 | awk '{ print $2 }' )
% echo "HOTP/T30/6 andrewlkho - ${KEY}" >> /etc/security/users.oath
% chmod 600 /etc/users.oath
