Re: N+1 Do we all need a pub bike?

I've got a Basil wire basket on the front of my bike. Brilliant - great for popping shopping in, and also gloves and such if you need to take them off mid journey. Much more convenient than panniers.

Re: What this stuff is

It's not acid - there's a reason they are called Alakaline batteries :-)

Re: Horns

Cars horns do go toot-toot if you press the horn gently twice.
It's not the horn which is aggressive - it is the person pushing it.

Re: Maps, paper or electronic?

My work involves providing GPS assistance to phones and calculating GPS positions - so I'm well aware that some models won't give a fix without assistance. It's the same reason versions of the iPad without a cellular connection have no GPS; the user experience of GPS can be very poor if there is no ...

Re: Maps, paper or electronic?

Some smart phones will not give a GPS fix unless they can contact a server to get satellite assistance data first. In theory they could do a full scan and just take longer to get a fix, but in practice they don't. That may not apply to all (I know it's not true of the iPhone, nor some of the Samsung...

Re: Maps, paper or electronic?

Many (most?) smart-phones will only give a GPS fix if they can contact a server to get assistance data - so in practice they won't work if there is no phone signal.
This can make a smart phone a lot less useful than a dedicated GPS if going off the beaten track.

Re: carrying a huge smartphone!

<pedant> Just one thing - GPS (and cell tower/wifi location) don't use triangulation. No angles involved at all. They work by computing distances to satellites or cell towers (or both), not angles. Trilateration is the word you want. </pedant> On tracking - many smartphones send back data (Cell towe...

Re: Tandem - First Ride

There's a question I've always meant to ask about tandems. Whenever I see a couple on a tandem, the woman - almost always the shorter person, is on the back. So all she can see is the back of her partner. Would it not make much more sense for the shorter of the pair to be at the front, then both can...
