If you’ve ever used the London Underground you’ll know that the beautifully presented, schematically laid out underground map is not, in fact, representative of the geographical layout of the tube lines at all. Worse still, some of these apparently disperate stations are infact a stones throw away from each other in reality, but as this isn’t represented on the map, making the requisite journey alterations needed to get anywhere on time when a line is suspended, or a station is closed or the wrong kind of leaves are on the track or some other such excuse causes the tube to slow to a crawl or stop all together, is often pure guess work and many of these short cuts are a black and secret art known only to cabbies, cockneys and underground staff.

Well, London Underground have made a really useful Flash app which shows the underground lines in their true geographical layout, over which you can superimpose the stations and, more importantly, the roads. Although it is of the central underground area and some stations are missing, so we do loose out on that but at least it’s a better orientation of London. Realistically TFL need to make it a comprehensive map as this will definately change peoples travelling habits and allow us all to optimise out journeys on the fly.

A lot of people have been asking me recently about Singletons so I thought I’d post on it. A number of developers have written on the Singleton class/pattern. Recently Grant Skinner wrote on the problems of using them in AS3, but I’ll get to that. I personally learnt my Singleton implementation methods from old skool Java developers and so far it’s been bullit proof, easily repeated, quick and reliable. But I thought I’d touch on not just what it is and how to make a Singleton work, but also some of the logic behind why a Singleton is built the way it is (so let’s hope I do a good job).

Some of you may have seen intelisea’s web site. Basically it’s a demo of an installed system which is used on luxury yatchs. Having downloaded the demo (I suggest you do the same) and tried it out, I contacted Phil Heinz (their Director of Systems Development - phew, that’s a big title Phil) and he confirmed : Read the rest of this entry »
