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.
Using CGI and Perl to put a simple application online. Sometimes still the best way.

These days, it's fashionable to embed Perl, PHP, Python or Rails within a web framework if you want to put your application code online - in other words, if you want to take logic that's tried and tested and make it web available. And there's much to be said for this fashion - it provides a whole series of facilities and security checks which you don't have to keep re-coding yourself. If you're writing substantial systems, I'll encourage you to use such a framework, and indeed I'll introduce to you Django or Rails as an extra day on the end of your Python or Ruby course.

BUT ... if you just want to add a simple, one-page script onto your web site, there's still a lot to be said for KISS - "Keep It Simple, Stupid" - and that can be achieved through the Perl and the Common Gateway Interface.

On last week's Perl course, I wrote a complete CGI example that looks up data from within a large data file - a simple, single page filtering application. It's robust, secure, easy to use and it doesn't use any of the complicated day-to-even-start frameworks. Source code [here]; data file [here].
