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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

It's great to use current and new technologies on your web site, but you want
to be able to suppot older browsers and more cautious users too; not everyone
has Flash, so you have to compromise?   Not really - you CAN sense whether or
not Flash is loaded onto a browser ... and call up alteratives (different links
and different images, for example) depending on what you find.<br><br>
<b>This demonstration tells you whether or not the Flash plugin is installed
on your browser.</b><br>
<SCRIPT LANGUAGE="Javascript">
<!--
document.write('Flash Status is '+flashinstalled+'<br>');
if (flashinstalled == 2)
        document.write('i.e. you do have Flash<br>');
if (flashinstalled == 2)
        document.write('and it is version '+flashversion+'<br>');
if (flashinstalled == 1)
        document.write('i.e. you do NOT have Flash<br>');
if (flashinstalled == 0)
        document.write('i.e. you MAY have Flash<br>');
// -->
</SCRIPT>
<br>Result of test should be above. You will not see any result at all
if you do not have JavaScript!<hr />
Now let's call up a static image if we're unsure of our Flash, or a flash
movie if we know we can (later that version 6)!<br><br>
<SCRIPT LANGUAGE="Javascript">
<!--
function writeOneScreen(sURL){
