An article in Weekend on Aug. 16 about walking around Manhattan misidentified the river beneath the Washington Bridge, which connects the Bronx and Manhattan. It is the Harlem River, not the Bronx River.

Can Tesla be agile to make cars ?

What many people enamored with the idea of agile fail to realize is where the limits are. Agile is efficient when the cost of making a change is lower than the cost of an iteration. In other words, your iterations have to be profitable (at least in aggregate.).

Deploying software to a server costs almost nothing, so you can iterate every five minutes and make money. Except when you make a mistake and deploy something broken, which can cost you in damaged customer reputation. In many cases these are costs that can be absorbed, but fail too often and the product is doomed.

Agile works by holding time and effort constant, but letting scope vary. That means using agile techniques to handle hardware projects where scope can't vary (like deploying routers to remote sites) can fail much more easily. If any component is delayed, the whole product is delayed, and other expenses rise: rescheduling installers often has a cascading effect on the rest of the project.

Library mis-use

This isn't to say that vulnerable people, children, and low-income families shouldn't be welcome in libraries: the monumental role they play in enabling social mobility cannot be overstated. Rather, it's to say that, when people are forced to use their local library as a replacement for child care, social care, or services for the homeless, something's gone seriously wrong.

With over 22,000 coffee shops in the UK, it's little wonder that workers-from-home flock to them in their droves. In many cases, they've got a much better shot at desk space, long opening hours and a hushed atmosphere than they could bank on at their local library today.

The sad thing is, many accept this situation without ever wondering what a generously funded library system could look like for them. You only need to visit the home page for Stockholm's public libraries for a stark comparison: bookable group study rooms, homework help, librarian appointments and well-stocked shelves. There's even, bizarrely, an electric piano available in one of them.

Strategic cycle network map, London

The strategic cycle network map

This is the capital's "strategic cycle network". The thick red lines are the existing routes - the Cycling Superhighways and Quietways, that have been spreading across the capital over the last few years. The thin red lines are those that are currently planned, and the green dotted lines are possible later connections.

If all this is delivered, the strategy says, 70 per cent of Londoners would live within 400m of a cycle route - a distance you can cycle in a couple of minutes.
