Submission + - Biologist creates self-healing concrete (cnn.com)

Mr.Intel writes: No matter how carefully it is mixed or reinforced, all concrete eventually cracks, and under some conditions, those cracks can lead to collapse. "The problem with cracks in concrete is leakage," explains professor Henk Jonkers, of Delft University of Technology, in the Netherlands. "If you have cracks, water comes through — in your basements, in a parking garage. Secondly, if this water gets to the steel reinforcements — in concrete we have all these steel rebars — if they corrode, the structure collapses."

But Jonkers has come up with an entirely new way of giving concrete a longer life. "We have invented bioconcrete — that's concrete that heals itself using bacteria," he says.

It's Seattle. "a new neighborhood" means "30 more minutes from work, minimum".

To be honest though, I don't see why someone would be upset about the design of the homes... the buildings look fine, and don't even look particularly out of place for Seattle architecture. They're not old, that's about it.

'Old'? I bet our European friends will be laughing their asses off at this descriptor.

Anything protected directly by user entry into a smart phone is bound to have no usable entropy by itself anyway.

Modern phones don't actually turn the PIN or pattern directly into an encryption key. Older phones do (and by "older" in the case of Android I mean, "actually quite recent but not latest gen"), but modern phones feed the PIN to a dedicated secure chip that only divulges the actual secret key when the PIN matches, along with keeping track of attempts etc. To break it you need to break the secure chip, which means either finding an exploit, or grabbing your local scanning electron microscope and beating the chips tamper resistance measures (wire mesh etc).

At least the political stuff, the spying stuff, etc. is 'stuff that matters'. This? Just bandwagon jumping clickbait. Is there no way this story could have been spun to include testing standards, analysis of effect on the game, or something even vaguely, remotely applicable to the audience of this site?

They already got a large commercial insurance policy for their drivers. Insurance companies care about money and risk, they aren't denying insurance for the period when the driver is alone but with the app switched on because of some specific high minded ideal, it's a commercial decision.

Yes, but that's a risk that the driver takes not the Uber customer. And coverage when the app is on but not being used is a relatively minor detail of insurance - it will get worked out in one way or another.

Uber isn't even cheaper than a regular taxi in many places. It can be more expensive. When I was last in SF there was never a time without surge pricing. Seems it doesn't hurt them though. Lots of people seem to prefer the Uber experience regardless of price.

Here we have an app that is putting the entire taxi industry out of work, while the apps creators become billionaires

As opposed to the owners of New York taxi medallions, who do no work at all whilst still getting rich?

Disruptive capitalism at its finest. Sure uber is cheaper for the consumer, but is it better for society? The money is feeding fewer people, and making a tiny number of silicon valley elite uber-rich.

Eh? Uber, at most, replaces the taxi cab dispatchers at the other end of the phone line. The cars still need drivers. If anything they're creating more jobs by making it easier to go everywhere by cab, so increasing the demand for the labour intensive service of driving.

Now when Uber start to phase out drivers entirely in favour of robots, then you'll have a point. But it'll be another round of the same debate that's been rolling for centuries.

As a Canadian, my taxi money isn't even staying in the country! Do taxis really need to be colonialist?

What, you only get driven by immigrants who cross the border each morning? I think you'll find plenty of the money goes to the driver and some gets kept by Uber. Well, why not use the Canadian competitor to Uber then? It's not like they have any kind of cutting edge technological advantage. It's just a mobile app and some databases.
