Here are some things about me or by me or whatever; the informal and
always-out-of-date 5-minute guide to DHD!
My big project is OpenTRV
which has the modest aim of cutting the UK's entire carbon footprint by 10%
(and/or Europe's by 8%) at low cost
by halving space heating costs especially for homes
in a simple and fiddle-free way!
With a little effort, and no hardship, my family and home/office seems to
have managed to cut down to ~33% of average 2007 UK household
electricity and gas consumption
and indeed as of 2010 we're roughly net "zero carbon" for them.
I've had a lot of fun getting to understand a little better our energy consumption
and how it might evolve in the future, with us even possibly going
'carbon-negative' and becoming net exporters of energy...
I run ExNet Ltd, a company
focussed on networked, distributed and parallel software based in
of London (16 Willingham Way, Kingston-upon-Thames).
See my gallery of multimedia
(mainly JPEGs) for Web sites; historically one of the most popular photo/art
sites in the UK with several million vistors per year. One interesting
aspect was developing and tuning Google's AdSense contextual ads.
I give away some of the code I write in the hope that it will be useful
to others and save a few wasted hours here and there... Remember: a month
hacking code can often save an hour's reading and thinking!
I find this public-domain list of the first 100,000 primes
useful in day-to-day coding so I've put up my local copy.
