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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

opendir(DH,".");
for $sd (readdir DH) {
next if ($sd !~ /\./);
next if ($sd !~ /[a-z]/);

I admit it ... when it comes to the "crunch" and I need a quick script to do some systems admin work, it still has to be Perl!
The script above is currently running, via another window, on one of our two dedicated servers. "It's a very old machine - you should upgrade it" said their technician as he did a hard reboot for us yesterday; hmmm - it's not *that* old, but having heard a comment like that I think I'll ensure we have a fresh mirror of each virtual host ...
Learn how to write perl PROPERLY - i.e. commented, nicely structured, maintainable, without constants hard coded ... on our Perl Programming course. That will also equip you to write 'nasty' little scripts like the one above when you have the need! (written 2009-11-19, updated 2009-11-20)
