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.
Learning to write secure, maintainable PHP

We're running a PHP course this week, and as ever I went around the room on the first day checking with the delegates what their "hot points" were, noting them on a board to the side to ensure that all the points ARE covered.

Security and maintainabily came up. And came up strong. Duly noted on the board, and aspects were covered right from the start of the course. These are vital subjects and it's no good at all learning just the mechanisms of PHP without being aware of these issues. You can write a dog's dinner in which all manner of traps could lurk, or you can produce a Picasso - and you should plan which from the very first paint stroke on the canvas!

So I'm delighted that my delegates are concerned about ... security, maintainability, fitness for purpose, usability, extensability. It tells me that they're on the right PHP course, and it's a pleasure to have their early inputs.
