Originally tit for tat was a stylised way (ie slang) for saying "this for that". (Interestingly "titfer" became rhyming slang for a hat).

The word 'tat' is also used colloquially in the UK to describe something of poor quality (I believe it came from something falling to tatters). Something described as 'cheap tat' is usually near to wothless / meretricious rubbish.

How well this applies to mobile operating systems is left to the reader to decide :-)

If you believe a London Underground train could get to 120mph, I've got a nice set of title deeds to the Houses of Parliament I can sell you at a very reasonable price :-)

This isn't a new thing - it's been done before...

I was working in Copenhagen about 8 years ago and the metro there was driverless; the London Docklands Light Railway (DLR) has been driverless for years.

One thing that's been conspicuous by its absence in all discussions is nationality. Will the Scots get their own passports? and how will they be allocated? By residence - how to handle ex-pat Scots in England and English in Scotland? How to establish the foundations for applying for nationality? Rescinding of UK citizenship when becoming a Scot?

Then how will Scotland pay for and staff up embassies around the world? they surely wouldn't want to use the existing ones would they? after all they are escaping from us - to want to ride on our backs would be hypocritical in the extreme.

If they do split and things go well for them - that's great; if things go badly and the evil English aren't available, who are they going to take the blame?

As I said - there's been a deafening silence over this.

I've had a similar experience - many times.

First of I am not a lawyer - but I can read Wikipedia :-)

So when we get to "we've detected a problem with your computer" I ask "how?" and get a stream of babble about seeing data which looks like a virus.

Then I ask innocently -- "so you can look at my traffic?" "oh yes and you definitely have a virus - we can see from how your PC is behaving" "so you can look at my PC?" "Oh yes"

I always ask - "are you sure about this?" to allow them to dig themselves even deeper into a hole and then ask for their name/company name (claiming I misheard at the start).

At this point I inform them that either (a) they are probably committing offences under one or more of Computer Misuse Act 1990, Data Protection Act 1998 or Regulation of Investigatory Powers Act 2000 -- or (b) if they want to own up (and I do know that they are lying because I'm not running Windows and my firewall is pretty tight) that attempting to obtain money through false pretences is an offence under the Fraud Act 2006.

"Which one do you want to choose?"

They usually hang up at this point having spent around 15 minutes with me when they could have been hitting another victim -- though one did ring back and shout abuse.

I went into my bank recently and got the hard sell about switching to internet banking.

This is something I've resisted, but I was told it was "quite safe" and "millions of people do it".

They had a so-called free cash-back offer on the debit card. I looked at the sign-up process and was told by the counter staff it needed a password of 6-8 characters - case insensitive and letters/numbers only.

For some reason they were surprised when I informed them that this was incredibly weak password scheme and that I wanted nothing to do with it.

Needless to say, I'm still refusing to sign up for any internet based banking and automated money transfers.

"People should have to work....." many of them DO.

A large proportion (possibly the majority - I don't have the stats to hand -- of those claiming benefits are in work but in low paid jobs.

Someone on minimum wage (or just over) cannot afford to live in large parts of the country. I know of a head chef who works 60 - 70 hours a week yet has no prospect of affording to rent [let alone buy] a small flat where I live -- and that even without food, heating, lighting..... Before we get the "free market will fix this, go and live elsewhere" arguments, without people doing jobs such as cleaning, catering... society would collapse.

Effectively the benefits system is subsidising those employers who pay low wages. However this argument is drowned out in the "reckless, lazy wilfully unemployed" messages put out (especially by some newspapers who could give lessons in propaganda techniques).

The politicians would probably not care.

Voter apathy is at an all time high in the UK. This can be read in many ways ('they are all the same', 'a pox on both your houses', 'they only care about getting re-elected and their cronies - not about us'...) but the net result of a lack of political party output would probably be welcomed by all sides:

  1. for the people at large, it's a pause from hearing someone spouting forth about how they'll promise a wonderful future [right up until 24 hours after the results are declared when promises spontaneously evaporate]
  2. for the politicians, less kept on public accessible records the better - they can then bury history and past broken promises [as the Tories did in taking their past web history off-line recently] - al less well informed populace is easier to bamboozle and less likely to think critically
  3. for the news media [who are pushing for this -- those most vocal are also those who delight in publishing the very stuff they'd like to see banned] it's less competition for eyeballs

If this seems cynical - it probably is: there is precious little to choose between the parties nowadays. After the expenses scandal (thankfully we don't have quite the scale of campaign contribution corruption over here [yet]) politicians in general are not highly regarded by many and a period of quiet while some other group gets bad publicity would be welcomed by them -- is this the hidden agenda behind this? ;-)

I know I'm never likely to do it but as a thought experiment...

Install a small photocell linked to a servo motor (via an Arduino/Raspberry Pi if you want to get into fine tuning).

Have the servo flip a mirror (nothing fancy, just plain glass -- could be coloured red for the rear facing one) which is sited by the windscreen and back window. Think of a SLR camera mechanism but larger.

Then when the antisocial idiot doesn't dip head lights (oncoming) or tailgates on full beam (behind) the mirror would flip up and give 'instant feedback' * allowing them to modify their behaviour.

The simpler implementation of a hinge on the dash/parcel shelf plus mirror plus piece of string to pull would be too obvious if stopped by police or your vehicle was examined after an accident.

* OK I know it's not truly instant, but close enough when considering human perception/reaction times

The points you raise are absolutely correct. When I first read about it [wish I could remember where], it was very much a Gedankenexperiment and was quoted in the form of a very long metal bar in deep space (so no oxidation, constant temperature...) with the sum of human knowledge in one scratch

Even so, as X becomes larger, the scratch gets closer and closer to the end, so that the loss or movement of individual atoms would significantly alter the value.

Actually measuring it, without introducing energy (and thus heat, and thus expansion and/or evaporation effects) is left as an exercise for the reader.

Knowing how to decode the bit string is yet another puzzle.

The transposition to rocks (and consequent introduction of further real-life error sources) was entirely my own fault ;-)

I cannot recall where I read about this approach so apologies to the originator for not granting credit where it is due.

A long piece of rock (or other material) can be used to encode a huge amount of data with just one mark.

You need a long flat rock and the means of measuring length very accurately. **

First, encode data as a string of bits.
Then take that enormous binary string and treat it as a really big number X and put the mark to divide the length of the rock into the ratio 1:X

The accuracy limits will be governed by the size of the rock, thermal and other causes for expansion/contraction and deformation and (depending on how accurately you make the cut / how much compression you want to achieve) quantum effects on the fine grained positioning.

Multiple marks on the same rock provide extra "layers" of recording.

Just imagine - the whole of Slashdot's debates reduced to a single scratch ;-)

** Actually you need a means of defining what you mean by length first - take into account surface irregularities... [cf lengths of coastlines - thanks Mandelbrot!!]
