Xmas Rail Chaos: Time To Stop The Holiday Works

So we have another story about how overrunning maintenance work on our railways has caused travel chaos. One of the things to remember is that we only hear about the overruns and not the successfully completed work. I would not be surprised if only a tiny minority of work overruns.

But that isn’t much comfort to those caught up in the chaos.

Somewhere within National Rail, there is a department that decides when engineering work can take place, and they will have made a calculation to determine when the least “costly” overruns can be scheduled. They probably make this calculation based on the number of travel hours lost.

But perhaps they are not considering the quality of those hours lost. Some travel is more valuable than other travel; not in simple economic terms, but including other factors such as the amount of distress caused.

Holiday travel is a bit different to everyday travel in that :-

  1. People tend to travel further and make more connections. Disrupting their travel could well leave them stranded in an unfamiliar environment.
  2. More “vulnerable” people travel for holidays – children and old people – who are less likely to cope well with the disruption.
  3. Frankly most normal people value their holiday trips higher than their work trips; missing a day’s work because you cannot get in is mildly annoying, but missing a holiday is devastating.
  4. Lastly, making alternative arrangements is much more possible during normal working hours.

Of course nothing will change because all this will make no difference to those in charge who have chauffeur driven cars to take them everywhere and who regularly get their ears bent by industry pressure groups.

Special Treatment for Former Members of the Armed Services?

Yes.

But why? Apparently there is something special about serving in the armed forces – special enough for the mythical (it has no legal basis and so is in fact not a covenant at all) Military Covenant to be a popular phrase. And even a factor in determining government policy.

But why does someone who has served 20 years in the Army catering corp deserve more and/or better services than an NHS nurse who has “fought in the trenches” (including volunteering for work in the Ebola-stricken countries in West Africa)? And who is most likely to suffer from PTSD? A nurse up to his arms in blood and gore? Or an Army cook who is up to her arms in spuds?

And when you come down to it, anyone who suffers PTSD – even a banker who has smashed up his Ferrari – needs special treatment.

Perhaps those who have been in the armed services should be first in the queue for specialist treatments but those programmes should be open to all who need them.

And perhaps the “Military Covenant” should be extended into a “Public Services Covenant” to include those other public servants whose jobs put them in harm’s way – the police, fireman, ambulance drivers, nurses, etc.

Muting Smartphones

Today I happened to come across a story about a priest who uses a signal blocker to stop phones from shrieking, bleeping, or blurting during church services. Very possibly illegal, although it’s quite understandable.

After all a church service is just like a theatrical performance and the distraction of phones is likely to put people off. We need more quiet at times – such as in the theatre, church, the quiet carriage in a train, or even a meeting room.

But a signal blocker is going too far – if there is an emergency, we need to be able to use our phones. And asking people does not work – there are always a few people who won’t bother to silence their phones. Not necessarily because they don’t care, but sometimes simply because they don’t think of it.

Rather than blocking phones, we need to tell phones to silent themselves automatically.

And it could be quite easy to do. In quiet zones, simply broadcast a well accepted SSID (“QUIETPLACE” perhaps?) and configure phones to automatically mute themselves when they see such an SSID. It would require support from phone manufacturers as most of us wouldn’t bother if we have to set something up – or even just install an App to do it, but it’s certainly possible.

Robin Knox Johnston: He’s Old. So What?

Recently, Robin Knox Johnston took part in a sailing race, and the BBC spent some time interviewing him and highlighting his progress throughout the race.

Fair enough, but why was it necessary to keep banging on about how old he is? Yes he’s old enough – after all he completed his around the world voyage in the year I was born – but it’s probably the least interesting thing about him and what he was doing.

In practically every interview with him the BBC did, his age came up … and many times it came up more than once. Anyone would think the BBC is under the impression that old people should be sitting in a rocking chair with a blanket on their knees drooling gently.

 

NATS Software Failure: Old Code or Buggy Code?

Anyone watching mainstream media for news about the software failure at NATS can be forgiven for thinking that old software is responsible for the problem that occurred recently causing many flight delays. The mainstream media seems to have clung onto the idea that the code is old and decided to blame that for the problems. You do have to wonder where they got these ideas from given that most journalists have the technology qualifications of a gnat. Perhaps from industry insiders who have a vested interest in selling new products perhaps?

Anyone who has written code can tell you that it is not old code that is responsible for software failures, but buggy code. Old code can be buggy, but so can new code. In fact as there has been less time to spend debugging it, new code is likely to have many more problems than old code.

That sounds like a recipe for leaving old code well alone. But it isn’t really. Old code needs to be updated and refreshed on a continual basis but not replaced in a “big bang” approach just because it is old.

Small changes and not big changes. Small changes are easier to do, quicker to do, and it’s feasible during testing to say that the small change is rubbish and to throw it away.

The more important a system is, the more important it is to evolve it towards the future rather than simply replace it with something newer and shinier.

And letting mainstream journalists dictate your IT strategy is always a mistake.
