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.

I admit it ... when it comes to the "crunch" and I need a quick script to do some systems admin work, it still has to be Perl!

The script above is currently running, via another window, on one of our two dedicated servers. "It's a very old machine - you should upgrade it" said their technician as he did a hard reboot for us yesterday; hmmm - it's not *that* old, but having heard a comment like that I think I'll ensure we have a fresh mirror of each virtual host ...

Learn how to write perl PROPERLY - i.e. commented, nicely structured, maintainable, without constants hard coded ... on our Perl Programming course. That will also equip you to write 'nasty' little scripts like the one above when you have the need!
