My name is Mike Lockhart, and this is my web log. I am a senior support sysadmin and larval web hacker for a well known Australian Open Source web content management company. I do mainly Linux and Matrix work, and dabble in some other languages and projects in my Copious Free Time. Before this, I worked for nearly 15 years in EDS and Hewlett Packard on lots of different systems.
I'm also married for almost 19 years and we are parents to three boys aged between 5 and 12 years. We live in Tasmania, where we grew up, returning here from New South Wales, in late 2013. We all feel very lucky to be living here, with family close at hand and an awesome, friendly and welcoming community around us.
On the Net, I go by the handle sinewalker, and while after 20 years I think I've outgrown it, it's still a unique username in most places. A newer handle I'm adopting is milohax.
On this web site you will find posts, pages, pictures and code that are in connection with my interests. I try to keep the stuff here as general as possible — any work-specific writings live behind a company firewall. This means that what you see and read here is (or was ) my own opinion and does not necessarily reflect the opinions or directions of my employers (past, present or future).
A major reason for building my blog with a static web page generator is so that
I can have fine control over type-setting. While this site is mainly a personal
blog (and so informal), I use notational conventions throughout. These are
common enough in online technical writings for the computer field but weirdly
not well supported by systems such as Blogger or Wordpress (or Matrix) which you
must fight against to use. Computer keywords are typed inline
like this, terms
and variables are italicised like that and code blocks use Colour Syntax
Highlightng. At least for the newer posts since late 2015. I may go back and
tidy old migrated posts.
You will notice that the English on this site follows Commonwealth conventions of grammar and spelling. That's a natural consequence of where I live. You will also notice frequent spelling errors which are not attributable to Commonwealth English -- that's a consequence of Rule 9. I've also recently adopted the Oxford Comma for its clarity and consistency.
This is not a "web 2.0" site: there are no comments enabled here. No-one comments anyway, and it adds a lot to the site load time and bandwidth. There's not much point in costing visitors that overhead for something that isn't used.

How this web site is made
Posts are typed using the Dvorak keyboard layout into Emacs on either an Apple PowerBook Mac, or a home made computer running openSUSE, usually on a Truly Ergonomic Computer Keyboard or a Sun Type 6 keyboard (grey version, with rearranged key caps).
Posts are generated from a mix of markup languages (typically
using the Nikola static web site and blog generator, and
published to GitHub Pages (via Nikola's
github_deploy command). The site is reachable via my own DNS, or the GitHub
