And I thought the stuff I work on was complex

With all the stuff I've been doing today, I realise that in railway terms it's like a heritage line on which just about all the pieces of rolling stock have their own differences and foibles and if you try to relay the tracks so many complex issues come up.
I have probably made a rod for my own back during two decades of teaching by having examples on the main site in the server in just about every open source language which helps create Electric Train's complexity. So I'm finding I need ... an odd Apache module I had forgotten about, Expect, the LWP.pm module ...
Few hours sleep now and I will probably switch over the image engine ... let me see ...






Guess I can add a "guess where THAT was" to the above ... though I have forgotten some!
