Welcome to Andrew Benham's Web Site
This site is updated fairly regularly, but times on the web have moved
on, so I don't see the need for the once ever-present "under construction"
Who am I ?
I'm a retired software engineer. I lived on the northern edge of London for
most of my life, but I'm now living in Wiltshire. My most recent job was
working for Demon Internet/THUS in Finchley, but a realignment
of the business in early 2010 removed my role.
My initials are ADSB, hence the domain name. There are several Andrew
Benhams on the Internet, so I didn't want to use my name for the domain.
Who am I not ?
I am not the UK branch of the Abu Dhabi Ship Building Company, despite
the many e-mails I get :-) (I suspect they mean adsb.co.ae).
There was a small fishing lake nearby when I lived in London and I
now live close to an Avon, but it would seem slightly impractical to
float a super-tanker on either body of water...
Note that the river is called the Avon and not the
River Avon. Avon is derived from a Celtic word meaning
river, so River Avon is tautology. In Welsh, a Celtic
language, the word for river is afon.
Am I the Andrew Benham you know ?
Well, that depends.
I've been associated with the following establishments:
- Eversley Junior School, Southgate
- Haberdashers' Aske's School, Elstree
- Southampton University
- Radiomobile, Hemel Hempstead and Neasden
- Marconi Instruments, St. Albans
- STC, New Southgate
- STL/BNR Europe/Nortel Networks, Harlow
- Demon Internet/THUS, Finchley
Am I one of the (insert place name here) Benhams ?
I've been doing a little research on my branch and twigs of
the Benham family tree. I'd be pleased to hear from anyone I'm related to.
We seem to be based in Battersea in the 1830-1860 period, near East Grinstead
in the 1870s, and Islington in 1890-1920.
In particular, I'm interested if there's any connection between our being in
Battersea and "Benham Street" shown in that area in
Charles Booth's Poverty Maps of 1898/9
(the site now occupied approximately by
Benham Close, SW11).
About 10% of the male population have deficiency of colour vision, most
frequently "red-green colour blindness". I'm one of the 10%. It doesn't
mean not seeing red or green, just that shades of colours look different
to me. The spectrum around red brown yellow orange green gets complicated.
There are some good descriptions out there -
Colour Vision Simulator Examples
Colour blind image correction being two of them. At least,
that's what I've been told - some of the pictures look identical to me!
The BBC Microcomputers were very popular in their time. Some people even
believe that time is not over yet... If you're in that number, you might
find my pages useful - for example, the BBC Master's real time
clock only understands the 20th century - unless you fix it!
One of my areas of interest is date and time issues (timezones, calendars,
week numbering, etc.).
Config files etc for DVB-T applications for the main London transmitter.
Not a blog but a collection of thoughts,
Various bits and pieces (or bits and bytes).
