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.
Object Orientation in Ruby - intermediate examples

It's when you teach object orientation - the fully Monty, including inheritance, static and dynamic methods and variables, and so on - to a complete novice to programming and that person finds it's one of the easiest parts of the course that you realise:

a) Just how many bad ole habits us ancient structure programmers have gotten ourselves into and ...

b) What an excellent and natural Object system languages like Ruby have. T hat's as compared to C++ with a bevy of files, Java with so much security it obscures the simplicity, or Perl with so many options and so much ability to sidestep objects. (Python has a similar, and great, philosophy too)

Here are the 'second level' examples from today - not the basic object stuff, which you'll find if you look back a couple of days.
