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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Performance Test
This page is used to test our web server's performance.

The provision of a web page is no longer as simple as just feeding out a flat file when requested. Small adjustments need to be made to content on every page - for example, to give our phone number as you would dial it to reach us. And then on other pages, the names of examples from our training notes will be added in dynamically, allowing further material to be added to our delegate support pages simply by copying files onto the server.

This is a "typical" sample page - just a few things change on it, but it does run through all our mechanisms and so can be used to see how much resource each stage is using. It's of internal use to Well House Consultants staff (and perhaps as a demonstration of a technique to our delegates) ... but the following table won't convey specific phase details to our visitors.
