Sometimes my work leads in strange ways. I have just found an undocumented feature (BUG) in one of the mobile phone carrier’s systems. It is a bug that affects about 0.0001% of users, but is causing me some problems. You see, to save money, I am telling some tracking units to stop transmitting overnight. BUT, and this is a big one, the tracking units are still connected. They are just not sending any data back.

This is causing the network to think that the unit is not connected, but at the same time think that it is still connected. This is the problem with wireless systems, working out who knows what when the communications are not reliable. Also the systems get very complex so things are not as easy as they would appear.

Obviously none of the cariers is going to let me look at the internals of their systems. Even if I did I could not see the source code, since they do not have it themselves. And if I did see it then I could not tell anyway since the code is so complex with to many variables.

Welcome to my world.

I am starting to recover from todays run, and thinking that it would be nice to go running again a bit later today. I am turning into a fitness nut 🙂 No way, only kidding. But I am feeling great, and a lot fitter…
