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.
Perl and CGI - simple form, and monitoring script.
In some ways, Perl and CGI (Common Gateway Interface) is "old hat", but some times it's still just what you need.
Over the last couple of days, I've been working with Perl, with a customer for an intermediate tutorial session on some aspects of the language such as Object Orientation and Regular Expressions, and we touched on "can I send the output through to a browser too". Yes, of course, and CGI is neat and straightforward for the task; we don't need scookies, sessions, frameworks, MVC or the like - just simple displays and perhaps the odd form (and we do need to consider the web security!
Two source code examples with links to demonstrations ...
1. A simple form which the user fills in with a height and a width. Reply gives the area, echos back inputs too. Script has "injection attack" protection to avoid use entering something silly - you need that even on the simplest of scripts. [see demo]
2. An administrator's tool to keep an eye on the server - the uptime
report, disc utilisation, and the status of another server too, checked via a ping. [see demo] (written 2011-09-17)
