For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

How does information that you enter onto forms get correlated elsewhere to reserve you a place on an airline flight, or to ship you the coffee beans you ordered? In this module, we look at the structure of the networks, such as the Internet, and the various services provided on them. This is useful background information for you if you're going to be responsible for a web site, or if you're going to be writing programs to run on computers on the Internet.

2246What difference does using the XHTML standard really make?
I enclose my HTML attributes in quotes - or at least when I remember, I do!
