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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

2863Writing a server in Java
My standard recommendation these days is that you don't write your own low level network code - but rather you use standard protocols and classes - i.e. that you use tried and tested ways of exchanging data.

1976Where is this IP address, IPv4 and IPv6
Do you want to know where in the world an IP address comes from? I often do and I've used a number of tools - but they tend to draw me fancy maps and lead me away from my page.
