For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Great new diagrams for our notes ... Python releases

When training, I project onto a white wall ... and I draw onto the projected image, and add extra notes and diagrams around the side too - after all, the whole wall is a whiteboard. Some of the diagrams and slides that I'll come up with are new / unique for an individual course, and I end up photographing the whiteboard or parts of it, and so do my delegates.


And I also photograph the board ....

Here's a sample diagram, showing how Python has gone through a series of updates. At version 2.3, "new style classes" were added to correct some (frankly) quite small issues - at least as far as the regular user was concerned - in the OO model / specification. And "old style classes" were retained, and still are up to release 2.6 and 2.7.

But there are other things that need(ed) changing, and without being held back by the need for ongoing source code compatibility, and so along came Python 3.0 ... now Python 3.1 ... which breaks some source code compatibility things. In Python 3.0, you can only use new style classes, print is a function which changes its syntax oh so slightly, and there are some other things. So I drew a strong read cross on the line from Python 2 to Python 3 ... but then a green line bypassing that cross to show there IS a way - an automated program - to make the change.
