Upgrading our training systems to all the current stable versions
Programming languages are the eye of the storm in software development - the calm in the midst of the gales, an area where changes are gradual and gentle. It really needs to be that way, for who wants to pay for development of code when it's going to have a short shelf life?
And so developers write code that's leading edge code and algorithms, but with languages that are merely modern rather than leading edge or bleeding edge. Code needs to work rather than be too clever to work. So I find myself only difting of late into Python 3 courses and still doing a lot of Python 2, and Perl 6 still sits on the horizon.
But operating systems march on, and the version we've been running on our laptops has been getting long in the tooth, grey in the hair, and has started to have bad breath. Still a fine operting system, but it's embarrassing when it tells your delegates it's rather out of date. So I'm taking the opportunity of few days clear of customer facing work to upgrade the underlying Linux release to the most recent "Long Term Support" version on our training systems, and install recent versions of the laguages and servers we teach on them too. A useful exercise, and I'm logging it here so that I can refer back to procedures later and clarify versions and options used for our delegates. But the log will be in a summary form - you'll be able to follow it if you've been through our Linux training ;-) ... or very likely if you've not as well.

Guadalajara completed today ... Albany, Caerphilly, Edinburgh, Frankfurt, Helsinki and Manticore to be completed tomorrow. Dharhan has disc drive issues; Brugges a cracked screen (and I will probably leave it as a "control" system. Izmir and Juneau (our old internal staff systems - smart blue covers rather than smart yellow ones) may also be brought into the fold, and we have a spare system to install too; I'll probably rename Manticore into the "places I have trained" series - poetic license and I'll call in Kintbury, which is near enough to Newbury and the final machine need to start with an "L" - it's going to have to be called "Liverpool"!
