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.
Coloured text in a terminal from Perl

If you're looking to do something in Perl and the back of your mind tells you that, surely, someone's done this before then there are two things to note:
• Someone probably HAS and
• It's probably available on the CPAN or as a built in module.

Thus when I was asked the question "How do I get coloured text in a terminal window in Perl" last week, I know there was going to be a module out there - and there is - Term::ANSIColor.

As ever, there's an excellent set of reference notes on th CPAN, but no complete cut-and-paste-this sample for you to try out, so I've written one and it's available here.
