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.
Who is watching you?

How would you feel if someone sat opposite you in a train, stared hard at your throughout your journey, watched what you were doing all the time yet without engaging you at all? I suspect you would find that it made your spine tingle - it certainly would with me, and it would make me wonder what that person's agenda was.

That same observation can happen on line. And that's why you hear so much concern at people putting their personal details on sites like Facebook - especially as the web crosses over into real life. And 999 times out of 1000, the person with the Facebook account won't even realise that they're having such an unhealthy interest taken in them.

I was going to post a security tip this morning ... but I've just been watching some very interesting activity indeed on our web site, so I'm posting this reminder to "keep your private parts private" to everyone - you may not know who is out there!.

Our policy has been - and remains - to make our training activities and examples available and open to our delegates, and to all comers, and we must remember that. And at times (drawing an analogy with the Olympics which seems topical!) we'll act as the pacesetter and be in the lead for much of a race just to be "pipped at the post" by someone who we've helped along all the way. A poor analogy as I don't feel I'm in a race but I suspect that someone else does.
