I wonder what the real step forward is (field of view? accuracy? software?), because that is not much aperture. 1.5 square meters in all, compared to 6 square meters on Kepler and 18 square meters on Hubble.

The collecting area of HST is ~4.5 m^2. (2.4/2)^2 x pi
Collecting area of Kepler is ~0.7 m^2

You also have to consider e.g. field of view and observation durations for use in planet searches.

I work a lot with data from astronomy satellites. A lot of the first steps of the analysis, and describing the spacecraft
and its instruments are very close to the same from paper to paper of mine. (And similarly for other people doing similar
work.) This results in a lot of near (and sometimes exact) duplication of text. However, I believe this is still valid
and necessary. The heart of the paper - i.e. the new results and conclusions - does still differ of course!

I can't justify two cars, and if I own a car, it has to be able to drive 1000 miles in a day.

If you routinely have to drive so far then an electric wouldn't work for you.
However, if driving long distances is rare then an electric plus occasional rental (e.g. zip) ought to work.

And a Cochrane review of speed cameras concludes:

The quality of the included studies in this review was judged as being of overall moderate quality at best, however, the consistency of reported positive reductions in speed and crash results across all studies show that speed cameras are a worthwhile intervention for reducing the number of road traffic injuries and deaths. To affirm this finding, higher quality studies, using well designed controlled trials where possible, and studies conducted over adequate length of time (including lengthy follow-up periods) with sufficient data collection points, both before and after the implementation of speed cameras, are needed.

A Cochrane meta-analysis of red-light camera studies concludes:

Red-light cameras are effective in reducing total casualty crashes. The evidence is less conclusive on total collisions, specific casualty
collision types and violations, where reductions achieved could be explained by the play of chance. Most evaluations did not adjust for
RTM or spillover, affecting their accuracy. Larger and better controlled studies are needed

If you look at this comparison chart you can see that the iPad Mini 3 is exactly the same as the existing iPad Mini with Retina Display (now called iPad Mini 2) with the exception of two things:

  1. It's got Touch ID
  2. It's $100 more expensive

I'm not entirely convinced that Touch ID is worth the extra $100. Hopefully the IHS teardown will indicate if there is anything else of value between the two.

If there was anything else worthwhile, wouldn't apple be boasting about it rather than us having to wait for a teardown?
I am convinced that Touch ID isn't worth $100 to me...

From the NYT today:

Federal health officials effectively acknowledged the problems with their procedures for protecting health care workers by abruptly changing them. At 8 p.m. Tuesday, the Centers for Disease Control and Prevention issued stricter guidelines for American hospitals with Ebola patients.

They are now closer to the procedures of Doctors Without Borders, which has decades of experience in fighting Ebola in Africa. In issuing the new guidelines, the C.D.C. acknowledged that its experts had learned by working alongside that medical charity.

The Doctors Without Borders guidelines are even stricter than the new C.D.C. directives
