Cargo ships are currently burning the dirtiest fuels available -- so-called bunker fuel. Regulation is finally forcing a degree of cleanup by 2020, limiting sulfer emmissions. Cargo shipping is ruthlessly cost-competitive, and fuel is curr

86% of my passwords are for low consequence sites. How much should I care if someone hacks my handle and posts ads on a chat site? Or reads registration-required articles under my registration? Or etc etc.

More farmland is lost to desert than gained to warmth. Pastureland in particular is affected, making cattle more expensive to raise. Also farming is energy-intensive and a rise in costs of fuel will pass on to food prices.

I agree. The climate science is overwhelming: temperature rise, sea level rise, and other related changes are happening on large eco-system-changing scales. There is no stopping it and even drastic action will only slightly slow the chang

It reminds me so much of the 1990's when they ripped all of the tall slides and monkey bars, all of the fast merry-go-rounds, etc. out of playgrounds for younger kids. It is just moving up the chain. Where can it go next? Employer-s

The article "Rameses II and the tobacco beetle" (PC Buckland, E Panagiotakopulu Antiquity, 2001) has a more probable take. In the century-plus these mummies were in museums, they were subjected to various insecticide treatments.

My big question (not answered in the FAQ) is will it be faster or slower than Scala 2.12? Having worked on a big Scala codebase, the slow compiler speed is one of the biggest downsides to the language.

I'm a little surprised it is as high as it is. I am used to thinking "64 bits is enough for anyone."

I don't see any reason they couldn't fly more satellites if their customer base justifies it. The problem they have relative to ground-based systems is the satellites are not stationary. So to increase coverage density on one sp

Any reason why chips couldn't be hexagonal or triangular? Either one would still tile a wafer, and go closer to a round edge.

Not really. Stock C64 plus 1mb cartridge. The big innovation was Pex's discovery of a way to output 8 bit samples by a single register write on the SID chip. The chip was never designed for outputing digital samples, and the approach

I bike-shedded in this thread about exponentiation. But taking a step back the bigger issue is there are so many poorly justified features thrown in. I don't have the feeling that the authors appreciate the appeal of C as a simple l

Idiomatic C would say: float discrim = b*b - 4*a*c; Using pow for a small integer power is a no-no: less efficient and less accurate. I agree that \ is an awkward choice. A Fortran-like double asterisk ∗∗ is out because of ambiguity

I think its much easier in a space where you already have a precisely measured framework. Disclaimer: I haven't prototyped this. I think with a good enough continuous camera movement you can track from a zoomed out or slow-pan view tha

Probably the human wasn't paying close attention. That is the problem with level 3-4 automated vehicles: a human who is not in primary control of the vehicle has trouble paying attention and is unable to take over control quickly if i

The paper says: "The adjusted population attributable fraction for all-cause mortality was 18% (95% CI 10·9–26·1), equivalent to 412 000 (95% CI 250 000–598 000) deaths each year." My opinion is still that translates better to &qu

Its amazing how little of a splash this report made in the media. I guess it is because it doesn't fit much of a narrative. The biggest sources of lead exposure were leaded automotive gas and lead-based paint, both of which were phas

The clickbait aspect is the teaser "had a deadly goal" which is designed to make you wonder "what was the deadly goal?" It's the same form as "You won't believe number 9!" in a clickbait top 20 list.
