For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

First Great Western can discuss issues relating to trains and travel in the
Thames Valley, South West of England, Cotswold and South Wales. Whilst

<br><br><i>Note - I wrote this page as a demonstration to show some features
in use on our <a href=http://www.wellho.net/course/php.html>PHP courses</a>
that we run in <a href=http://www.wellho.net/share/melksham.html>Melksham, in Wiltshire</a> - a town of 24,000 from which First have withdrawn most trains, leaving
us with just 2 each way daily. Some 40% of our customers used to arrive in the train by town ... but now it's the car, the bus or the taxi. What a shame - and what a shortsighted decision by someone (not necessarily First)!</i>
