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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

Very frequently, IT system users find they've got a data file in one format and they need to filter it and transform it.

I heard Ruby described as "Perl Five and a Half" - and I thought "how apt".

But Perl's ...
2700The same very simple program in many different programming languages
I was asked how many languages I teach yesterday - and the answer's quite a few; at times, it's almost "the more the merrier" as to a very great extent they are varieties on a theme much of the way - but different balances of features make some languages especially good for some uses. As a geek's relaxation ...
