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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

When you have a web application running, you'll be providing ...
3698How to stop forms on other sites submitting to your scripts
From time to time, many of us web site authors and maintainers put a form on our site which submits data to another site. It might be something as simple as a Google seach box or a webmail login page. If you're developing a page / form which you do not want to be filled in remotely in this way, you ...
2238Handling nasty characters - Perl, PHP, Python, Tcl, Lua
Are your writing or maintaining a web based application that uses forms? If so, you have better be aware of some of the nasty characters that are around! The < character, when echoed back from a users's input 'unchallenged', may form the start of a tag. So that in a relatively benign case, a user ...
