I guess it had to come – I’ve tried out SMS systems for locating hotels, petrol stations and hotspots.  Now, one of the London Boroughs has started a system to help mobile phone users to locate the nearest public toilet.

Actually the area covered would appear to be still rather small, but if the rest of the capital joins in then it could be a useful resource.

But will it be any good in rural areas, where public toilets are often locked – the key being kept in local shops?

I’d like to suggest extending the system – to allow such toilets to be unlocked using the same SMS system.  Any vandalism would be easily traced back to the mobile phone owner that unlocked the toilet.

Does anyone else think that this is a good idea?

Today’s news shocked me at first: Toshiba has effectively conceded defeat for the HD-DVD format and Blu-ray is the winner.

It was a battle that, although it had interested me, was not one that I was going to let affect me. I am currently quite happy with the DVD standard for video and data, and although it’s interesting to see where the technology is going, I already see enough problems with the DVD subformats to worry too much about any new ones.

That said, I am worried that in the not too distant future, we will not be able to read the DVDs that we write today.

When I got married I archived all of the digital pictures on a CD and gave copies of this CD to our relatives. One of my friends asked me if I was sure that I would always be able to read them. At the time I thought that the CD format was pretty much standardised, and the pictures were in JPEG format – something that I couldn’t see dying out too quickly.

And yet now I find myself really wondering if I will be able to read the CDs in 10 or 20 years time. What will come after Blu-ray? Will the drives read the ‘old’ CDs? Or will reading a CD then become like reading a disc today.

Actually I still use 3.5″ discs as one bank that I deal with accepts DTA files on them. I also use one when I want to print flyers at the local copyshop.

So currently I find myself using 3.5″ discs, CDs and DVDs for my data, not to mention my USB stick and the SD card in my PDA and the MMC card in my mobile phone.

Is Blu-ray going to be just another format to add to the list?

I remember the VHS/Betamax time at the beginning of the 1980s – the current discussion has often been compared to this. At home we had VHS, at school Betamax. At least one person I knew had betamax at home, but everyone else had VHS – and eventually my school changed as well. Whatever happened to those betamax recorders?

The fact is, that I still use VHS cassettes. Yes, I can record a DVD instead, but when I want to play it somewhere else there are always compatibility questions: is it +R, -R, +RW, or -RW? Has the last session been closed? These two simple questions determine whether or not I can watch my recording on other equipment. VHS does not, normally, have this problem (although I did once have an SVHS recorder…)

Will Blu-ray bring the compatibility that VHS once did?

Here’s a fun sport to try out: Speedcabling.

The idea is that you try to untangle a jumbled up mix of computer wires, and do this against the clock.  The first competition of this kind has been held in Los Angles, the article reports.

It’s the sort of thing that I often do for my customers – labelling all the cables and them removing them all, only to replace them with a much neater arrangement, preferably using new, colour-coded cables.

But once I remember doing this in the server room of a company with about 50 employees.  I spent an entire Saturday morning re-wiring all the patch fields to make the system more presentable and understandable.

Another time I had to remove old network cable out of the ducts in the wall, and back then this was so-called BNC-cabling, where everything was joined to one big circuit – not like the structured cabling used today.

Again, I spent several hours trying to rescue as much cable as possible to be able to re-use it later.  But sometimes there was not other way than to cut through it, especially where the plugs had been attached after the cable had been put through specially-made holes in the wall.

So how would I fare in a speedcabling challenge?  I think I’d be pretty good.  When the sport makes it Europe, maybe I’ll have a got!
