    i thought the iphone used aGPS which utilises Cell triangulation first then gps to fine tune. Got to admit, i have worked on GPS systems in the past but not for mobile phones

    Wasn't there a story in the Guardian this week, about a woman who got a slap on the bum from a passing motorcyclist?

    No excuse for that, of course. But unsurprisingly, this hack had to call it 'casual sexism', and by implication, tar all men with the same brush.

    Good Idea, but drivers think they are giving enough room. Had one a few weeks ago, quiet road, close pass. Chased him down, and spoke with the drive.

    Who thought he had given enough room, to be honest if it was rush hour, I would have excepted the pass, but on a Sunday morning, with enough road to give me a couple go feet of space!

    I did ask him how I might have felt, and could we try the whole thing in reverse with me driving the bus!

    Sadly prevention rather than cure is more expensive and to degree, difficult to quantify the overall success for cost. I do agree entirely but we do live in a world of cure rather than prevention

    Every single study/analysis I've seen on preventative programmes, of varying kinds have shown a large net benefit to society.

    Better grade schools = Net benefit
    More socialisation activity (think youth clubs) = Net benefit
    Better skills training for school leavers = Net benefit

    The cure is very expensive, prevention is ROI positive.

    What is this 'net benefit'?

    I don't mean to be cynical (OK, I do...), but claiming that measures 'prevent crime' is a bit like claiming that every capital execution 'saves two lives'.

    It's nonsense. It is impossible to calculate crimes that are not committed.

    My view is that scum is scum, and no matter how much money you toss at a social club for teenage boys, if one of them is going to grow up to be White Van Man who kills someone in a 'punishment pass' gone wrong, then he is going to grow up to be White Van Man who kills someone in a 'punishment pass' gone wrong.

    Scum don't come from any particular class, creed or colour. But equally axiomatically, all the 'education' in the world cannot change stupidity and malice. All it can do is to impart knowledge.

  • Advice on climbing bike 5k-6k1 year 5 weeks agoWell in that case, go right

    Well in that case, go right ahead!!

    I think I see it as being that simple because it's essentially the same approach as is necessary in my work - people think that I make lots of decisions, but in reality I just try to understand all the constraints really well and the solution kind of picks itself (albeit only to a certain extent). The problem, of course, and indeed the strength of a forum, is that unless you've tried every component going, you don't necessarly know what your preferences are. If you're spending that kind of cash though, do you have a relationship with the shop such that they will let you take out some of the higher end stuff for extended test rides?

    Now if I just hadn't got married and had these pesky babies, I'd probably be buying the same kind of bikes...

    Where are you anyway? Did you see that thread on De Ver bikes? Strikes me that this kind of money could buy you anything you wanted at their prices.

    Sky could do a lot more...

    No.

    No, they couldn't.

    This is exactly the misapprehension that the councils, the government, the Mayor of London etc etc keep feeding us.

    Cycling sport does nothing whatsoever for conditions that ordinary people on bikes (not "cyclists"; people on bikes) have to suffer. It's great that we live in an era where British pros are winning Tours de France, Olympic medals, and what have you. It's great that Hoy and Boardman and Armitstead are encouraging the ordinary citizen to get on a bike, but the issue here is the commitment of local authorities to provide facilities.

    The desire to ride is there already. That's why the voices (official or sporting) that urge people to ride can make no difference; people already want to ride. It's the things that suppress the desire that are the key.

    Building real, proper facilities is the task ahead. Only this will stop the suppression. Only this will free the will of the riders-that-would-be. And that's the reason why Sky, British Cycling, the voices of the pros, and so on, cannot help us ordinary people who just want to ride from A to B. The pros can't make the councils build decent paths; the pros can't make the police enforce the law.

    The Olympics didn't improve cycle facilities in London.

    Wiggo and Froome's Tour-derived national stardom didn't increase the numbers of utility cyclists.

    The Grand Depart will not improve road conditions in Yorkshire (except for the resurfacing along the route that embarrassed councils are being compelled to carry out).

    The connection that self-aggrandising politicians make between sporting success and ordinary cycling is as preposterous as if they had said that Mo Farah's marathon wins will improve conditions for pedestrians.

    Sky's influence is limited to "serious" cyclists. The numbers that turn up for the Sunday Grovel with the local chain gang might be temporarily boosted; the CTC might get a slightly larger membership pool; the next screening of the Ghent-Wevelgem* might get more viewers. But for anyone who just wants to pop round their mate's house or go to the shop for a pint of milk and a loaf of bread, cycling numbers are not the least bit influenced by Sky or by anyone like them.

  • Shimano RS81C24 Wheels1 year 5 weeks agoI can't quantify "stiffer"

    I can't quantify "stiffer" but I have a pair of RS80s (10-speed version) and find them to be really nice wheels. They certainly feel lighter and more responsive than my RS10s.

    RS61s, previously sold as Ultegra, are very similar but without the flashy carbon laminate and are quite a bit cheaper. If I was shopping now I may well have bought these instead.

    1. What's on offer at your local shop.
    2. Can you get a proper bike fit there to determine if the bike will fit.

    adrianoconnor wrote:
    Me too. In fact, I once got a camera for using on my commute, as a gift from somebody who really meant well, but I won't use it. When I'm riding:

    #1 priority is to stay safe, and arrive in one piece
    #2 priority is to enjoy the ride (which includes riding fast and getting PBs, of course)

    Dwelling on dangerous behaviour won't help either of those goals, and if I get knocked off, the new #1 priority would be 'getting back on the bike' -- it would absolutely not be 'getting revenge on the driver' (which would be even more all-consuming than posting video of near-misses).

    And when I do get cut up by a driver who mis-judges how quickly I'm approaching, or when someone passes by too close, I just let it go. Even when I'm queuing in traffic and a car is beeping me to get out of the way (bizarrely happens once every few months on the same stretch of road -- the cars never, ever have anywhere to go -- we're literally queuing through the city centre), I'll just give the driver a big smile and a thumbs up before disappearing off down the road.

    My priorities are exactly the same, but the camera is a great idea purely to dispel the "my word against yours" scenario in the event of an incident. Brilliantly, you can even combine it with use of Strava (or whatever). Thus:

    Angryman: "You came out of nowhere, weaved all over the road, and were going far too quickly!"*
    You: "Nope."

    Police or the courts get involved, and you turn up with video evidence, GPS logs of your speed, and a smug grin.

    A happy byproduct is that it also makes me swear less, since I let the camera do it's job and I don't get as angry. I've never even transferred any footage to my laptop except when testing the camera angle and position, and certainly haven't uploaded to the web.

  • Advice on climbing bike 5k-6k1 year 5 weeks agoNo offence taken but yes I'm

    No offence taken but yes I'm genuinely doing this, tried many different bikes recently, not impressed with 11sp or any mechanical setups after using ultegra 10sp di2 for a long time. It's not as simple as your making out, I suppose I'd like to try buying a frame and choosing my own components but I'd never make my mind up!

    I'm not judging people who spend under £1,000 on a bike, there is plenty of choice for them, loads of different reviews, upgrade potential. Sorry but I'm just seeking some thoughts/opinions/advice on dura ace di2 11sp in particular. I know a few people who have bought a bike and are unhappy with it for various reasons, sizing etc, I'm just trying to make sure that's not me.
