...the Autonomous Precision Landing Navigation System might come in handy. It combines camera images with elevation maps using methods “employed by cruise missiles for decades,” although you don’t hear a lot about safe landings by cruise missiles."

I can generate all natural numbers using only a single number and a single operation: the number 0 and the S operation "add +1". Proof: 0, S0, SS0, SSS0,...

Where is my prize? (What a stupid video.)

For years iTunes is plagued by well-known bugs affecting its core function of playing music (ie it skips in the middle of a track to the next song (bug report) (demonstration)). I'm surprised they took care of this one "so quickly".

Many of my mp3-s from which iTunes jumps and skips to the next song are not VBR, but fixed bit rate mp3-s.

But thanks for the guess, for a second I hoped that this could be the source of the problem..

Between this and iTunes failing even in the most basic task of playing music, I wonder why anyone still uses Apple music services.

I second the TomTom Spark, here is a quick overview from the best sports-watch review site:

TomTom Spark impressions.

I use an earlier version of TomTom Cardio, which is really great. In case you'd want also want to have optical heart rate monitoring (which the TomTom Spark hs) then it's pretty much the only choice, as most other optical heart rate monitors are quite inaccurate when it comes to sports, see D.C. Rainmaker's review of them on the same site.

Indeed, who is going to tell what constitutes "serious emotional distress"? Are we simply witnessing the creation of "a right to be offended", or a new era of psychologist judges?

While the new info about the cockpit door mechanism seems compelling, it may be worthwhile to take a look at the tragic catastrophe of Germanwings in the light of a crude calculation that illustrates just how staggering is the number of hours flown per year.
Let's assume that on average a person faints only once in a lifetime, and that on average we spend 5 minutes a day with seeking out and using the restroom. Then on average we should expect in every 70*365*24*24*60/5 = 177 million hours that a pilot faints while another is using the restroom, assuming that these two events are uniformly distributed and independent. According to IATA the total number of flight hours in 2012 was 45 million. Dividing the two numbers we see that we should expect such a joint occurrence to happen once in every four years. That it does not happen this frequently is essentially due to the retentive heroism of the pilots, that they tend to stay put even when the urge comes until they guide the plane to safety.

The dimensions of the Prelude FLNG is 488m x 74m (1,601ft x 243 ft), and thus it is way larger vessel than the Triple E. The hull was already launched last year. The only reason it is not the largest ship is that it does not have its own engines to propel itself.

From TFA:

The study reveals nothing about the nature of the link between socialism and dishonesty. It might be a function of the relative poverty of East Germans, for example.

Although the historically observed relative poverty may indeed be causally linked to choice of an economic-political system, even that would not be sufficient to appropriately identify the economic-political system as the cause of the alleged differences in moral aptitudes.

Your calculation is way off, only 14kg of Batrachotoxin would be needed to render 38m gallon of water lethal, not 15 tons. One can carry that much in a backpack, not to mention that this is for doses that are lethal to everyone (if evenly distributed); much less would be sufficient to cause serious health issues for the majority who drinks from it.

(According to wikipedia sources 100 microgram of Batrachotoxin is lethal for a 68kg person. 100 microgram in every liter of 144,000,000 l (=38m gallon) of water requires 144,000,000*100microgram = 14.4 kg poison.)

This is of course not a justification for draining this amount of water from the pool every time the pool is micturated upon in the fair city of Portland.

As it is explained in the FAQ, the blockchain is not used for distributing user's messages. Only user registration and authentication is based on the Bitcoin protocol. The blockchain only grows in proportion with the number of registered users, with a few hundred bytes per user. Even with a widespread adoption that is still a quite managable size we are talking about.

Are there any good guesstimates on how small a tokamak-based fusion reactor (which produces more energy than consumes) can become? Theoretical limitations on size of the reactor would have obvious implications for pragmatic issues. AFAIK there is very little limitation on how small fission-based reactors can get.
